Madagascar

Madagascar is an island country in the Indian Ocean off the southeastern coast of Africa, separated from the mainland by the Mozambique Channel. It is the fourth-largest island in the world and, by most geological accounts, one of the oldest. Its population is roughly 30 million, most of whom speak Malagasy, an Austronesian language that is unrelated to the languages of the nearby African mainland. The country's identity rests on a combination of physical isolation, long-term evolutionary history, and a cultural mix of Southeast Asian, African, Arab, and European influences.

The island matters to science and policy for two main reasons. First, its long separation from other landmasses produced an exceptionally high share of biodiversity found nowhere else, including the lemurs, and it is therefore treated as one of the world's priority conservation regions. Second, its recent history, from French colonial rule and the post-independence republics to the political crisis that began in 2025, shows how governance, energy and water supply, and economic inequality interact. The entry explains the island's geological origins and climate, its ecosystems and species, the settlement of its people and precolonial kingdoms, the colonial and independence periods, and the constitutional and political system, including the 2025–2026 transition. It then covers the economy, population and society, language and culture, health and education, infrastructure, environmental threats and conservation, the history of scientific exploration, and Madagascar's place in regional and international affairs.

Geography and climate

Madagascar lies in the western Indian Ocean, separated from southeastern Africa by the Mozambique Channel, approximately 400 km wide at its narrowest crossing to the island. It is the world’s fourth-largest island, after Greenland, New Guinea, and Borneo. The country, including smaller offshore islands, covers approximately 587,000 km². The main island extends about 1,570 km from north-northeast to south-southwest and reaches approximately 570 km in width; its southern extremity lies south of the Tropic of Capricorn. (fao.org)

The central highlands form the island’s principal topographic axis, with extensive uplands approximately 800–1,800 m above sea level. Rather than a continuous level plateau, they comprise hills, intermontane plains, deeply incised valleys, and mountain massifs. The capital, Antananarivo, occupies the central highland region. To the east, steep escarpments descend towards a narrow coastal plain, whereas the western side slopes more gradually through broken country into broad lowlands facing the Mozambique Channel. The southern and southwestern lowlands include sandy plains and dunes. Maromokotro, in the northern Tsaratanana massif, is the highest summit, at 2,876 m. (fao.org)

The highlands also divide the major drainage basins. Westward-flowing rivers include the Betsiboka and its tributary the Ikopa, the Tsiribihina, Mangoky, and Onilahy; their longer courses cross broad plains before reaching the Mozambique Channel. Eastern rivers, including the Mangoro, Mananara, and Maningory, generally have shorter courses and can carry substantial flows down the steep eastern slopes. The Maningory drains Lake Alaotra. In the far south, many watercourses are seasonal or ephemeral, flowing after heavy rainfall but becoming dry during the dry season. (wildmadagascar.org)

These rivers transfer material produced by inland erosion to floodplains, estuaries, and the sea. The Betsiboka carries conspicuous reddish sediment from the central plateau into Bombetoka Bay, where deposition and tidal currents form islands and sandbars. Intense storm rainfall can greatly increase this transport: after Cyclone Gafilo crossed northern Madagascar on 7–8 March 2004, photographs from the International Space Station recorded widespread flooding and a large red sediment plume entering the estuary and adjacent ocean. Sediment movement therefore links upland processes directly to coastal landforms and waterways. (eol.jsc.nasa.gov)

The annual climatic cycle comprises a hot, rainy season from November to April and a cooler, generally dry season from May to October. Northwestern monsoon circulation contributes to summer rainfall, while southeastern trade winds are especially influential during the cooler season. Moist oceanic air rises against the eastern slopes, cools, and produces abundant rainfall; locations farther west receive less moisture after the air crosses the highlands. Elevation also lowers temperatures in the interior. The main tropical cyclone season broadly coincides with the November–April rainy period, bringing episodes of strong winds, heavy rainfall, and flooding, particularly along exposed coasts. (earthwise.bgs.ac.uk)

Rainfall varies sharply across the island: the humid eastern coast commonly receives approximately 1,500–3,500 mm annually, with northeastern locations exceeding 3,000 mm, while parts of the semi-arid southwest receive less than 400 mm. The east remains comparatively wet even during the island’s cooler season; the west has a more pronounced dry period, and the south experiences prolonged water scarcity. These gradients help distinguish eastern evergreen rainforest and upland moist forests from western seasonally dry vegetation and southern drought-adapted formations. They provide the climatic framework for regional differences in habitats and biodiversity, although soils, elevation, and land-use history also shape the vegetation found at individual sites. (fao.org)

Geological origins and isolation

Madagascar is a fragment of the former supercontinent Gondwana, rather than an island built entirely by oceanic volcanism. Its separation from Africa began about 165 million years ago during the Jurassic, when Madagascar and India remained joined within eastern Gondwana. Rifting and seafloor spreading opened intervening ocean basins, while the Madagascar–India block moved southward relative to Africa along the Davie fracture system. By approximately 118 million years ago, Madagascar had reached roughly its present position relative to Africa. A second breakup separated it from India around 88 million years ago, accompanied by extensive volcanic activity. These dates identify stages in prolonged plate-tectonic processes, not instantaneous separations. (sciencedirect.com)

The island’s crystalline basement preserves a much older history. Approximately its eastern two-thirds consist predominantly of Precambrian and early Paleozoic rocks, including gneisses, other metamorphic rocks, and granitoids. The Antongil–Masora craton contains rocks about 3.3 billion years old, while much of the central Antananarivo terrane consists of approximately 2.5-billion-year-old gneisses. These crustal blocks were subsequently assembled and reworked during the Pan-African mountain-building events associated with Gondwana’s formation. Younger sedimentary rocks dominate the western third, particularly the Morondava, Mahajanga, and Antsiranana basins. Their sequences extend from the Carboniferous to recent deposits and record continental sedimentation, marine incursions, and the development of rifted margins. (academic.oup.com)

Volcanism occurred in several distinct episodes. Late Cretaceous lava flows and dykes, linked to the India–Madagascar breakup and the proposed influence of the Marion hotspot, occur along both eastern and western margins. Much younger volcanic centres include the Ankaratra massif in the central highlands and the nearby Itasy field. Ankaratra developed over approximately the last five million years; dating reported in 2021 identified southwest Ankaratra eruptions approximately 45,000–110,000 years ago. Weathering of volcanic material produced the dark, fertile soils around Antsirabe, contrasting with soils developed on the older crystalline basement. (agupubs.onlinelibrary.wiley.com)

Long isolation does not mean that all living Malagasy organisms were present before continental breakup. Molecular evidence indicates that lemurs, tenrecs, native carnivorans, and nesomyine rodents colonized after Madagascar became an island, probably from Africa. A 2013 synthesis placed lemur arrival at approximately 50–54 million years ago, tenrecs at 25–42 million years ago, and carnivorans and rodents mainly in the early Miocene. Rare colonizations followed by speciation therefore helped generate the island’s distinctive fauna. In 2010, Jason Ali and Matthew Huber modelled Paleogene ocean circulation and found eastward currents capable of transporting vegetation rafts from northeast Mozambique and Tanzania toward Madagascar. Such rafting provides a mechanism by which small terrestrial animals could cross the sea without a continuous land connection. (journals.plos.org)

Land-bridge hypotheses nevertheless remain part of the scientific debate. A 2021 study argued for temporary Cenozoic connections or stepping-stone chains across the Mozambique Channel, whereas Ali and S. Blair Hedges’s 2025 review favoured overwater dispersal for 26 of 30 terrestrial-vertebrate lineages examined, identifying only two as Gondwanan remnants and leaving two unresolved. Distinguishing these explanations requires combining seabed geology with phylogenetic estimates of colonization dates. Direct fossil testing is constrained by an approximately 65-million-year gap in Madagascar’s terrestrial vertebrate record; lemurs have no known pre-Pleistocene fossil record on the island. (doi.org)

The Late Cretaceous Maevarano Formation in northwestern Madagascar preserves an earlier fauna. Its seasonally dry floodplain deposits contain *Majungasaurus crenatissimus*, an approximately 6–7-metre-long abelisaurid predator, represented by numerous teeth, skulls, and partial skeletons. Mammals also inhabited this dinosaur-era landscape: Adalatherium hui, described in 2020 from a remarkably complete skeleton, belonged to the extinct Gondwanatheria and dates to the Maastrichtian, approximately 72.1–66 million years ago. Its unusual anatomy was interpreted as consistent with more than 20 million years of insular evolution. Much younger cave deposits preserve a different mammalian assemblage: late Holocene remains at Ankilitelo include giant lemurs alongside tenrecs, rodents, carnivorans, and bats. (sites.ohio.edu)

Biodiversity and endemism

Madagascar’s endemism—the restriction of organisms to a particular geographical area—extends beyond individual species to entire evolutionary lineages. A 2022 synthesis led by botanist Alexandre Antonelli recorded 11,516 described native vascular plant species, 82% of them endemic, and 1,314 native terrestrial and freshwater vertebrate species, with approximately 90% endemism. All native amphibians and non-flying terrestrial mammals occur naturally nowhere else. These figures describe specified groups of native organisms, rather than a single percentage applicable to the island’s entire biodiversity. Fungi and many invertebrate groups remain much less completely documented. (kew.org)

Lemurs constitute Madagascar’s endemic non-human primate fauna. Their recognized diversity has increased through discoveries and taxonomic revisions: the national profile published by the Convention on Biological Diversity lists 104 species and subspecies, whereas IUCN referred to 112 known species in 2023. The 2020 IUCN Red List assessment covered 107 surviving species, of which 103 were threatened with extinction, including 33 classified as Critically Endangered. This exceptionally high concentration of threatened species places lemurs among the most threatened mammal groups. The figures refer to different inventories and assessment dates; a newly recognized species does not necessarily receive a conservation assessment immediately. Habitat destruction and hunting are major pressures, although their extent and severity differ between species. (cbd.int)

Other mammals include the endemic families Eupleridae, encompassing the fossa and other native carnivorans, and Tenrecidae. The fossa (Cryptoprocta ferox) is a lemur-hunting predator whose cat-like appearance does not indicate membership of the cat family. Hedgehog tenrecs likewise evolved their defensive spines independently of hedgehogs. Endemic bird families include the ground rollers, asities and Malagasy warblers, while mesites form an endemic order. (tbguedes.com) Chameleons illustrate endemism at a finer geographical scale: many dwarf species of Brookesia occupy very small ranges. In 2021, Frank Glaw and colleagues described Brookesia nana from northern Madagascar; its adult male specimen measured 13.5 millimetres from snout to vent, excluding the tail. (nature.com)

Adaptive radiation has produced ecological differentiation within several Malagasy lineages. The island’s vangas diversified into birds with markedly different bill sizes, shapes and feeding strategies, allowing related species to exploit different foraging niches. Molecular studies support their diversification from a common ancestral lineage rather than repeated assembly of unrelated colonists. (pmc.ncbi.nlm.nih.gov) Plant specialization is conspicuous in the southern spiny forest. Alluaudia procera, a member of Didiereaceae, stores water in fleshy stems and sheds its leaves during the dry season; its spiny, upright form can exceed 15 metres in height. Madagascar also supports six endemic baobab species, including Grandidier’s baobab (Adansonia grandidieri). (kew.org)

Regional diversity is not interchangeable. Eastern humid forests and northern mountain massifs contain much of the island’s recorded species richness, whereas southwestern spiny vegetation supports distinctive endemic assemblages despite lower overall richness. Western dry forests contain numerous organisms absent from eastern rainforest, including characteristic baobabs, tortoises and dry-forest birds. Major rivers have helped separate western centres of endemism, while past expansion and contraction of forests under changing rainfall regimes further differentiated their biotas. National endemism therefore differs from local endemism: a species confined to Madagascar may inhabit several regions, whereas another may occur only within one small forest or mountain system. (tbguedes.com)

Published percentages vary with the organisms counted, the geographical boundary and the treatment of taxonomy. The Convention on Biological Diversity’s country profile gives 96% endemism for vascular plants and 37% for birds, compared with 82% for described native vascular plants and 56% for native terrestrial and freshwater birds in the 2022 synthesis. Such inventories differ in coverage and date; including introduced organisms, migrants or occasional visitors changes the denominator. Undescribed species also matter: the synthesis estimated that incorporating approximately 2,550 undescribed vascular plants could raise plant endemism to 87%. These estimates distinguish documented diversity from projected diversity rather than establishing one universal “percentage endemic” for Madagascar. (cbd.int)

Settlement and precolonial kingdoms

The date of first human arrival remains disputed because evidence of occasional visits does not necessarily establish continuous settlement. A 2018 study interpreted marks on elephant-bird bones as evidence of butchery more than 10,000 years ago; other researchers have questioned such interpretations and proposed much later chronologies. A 2019 review of radiocarbon dates documented estimates differing by roughly 9,000 years. More securely dated settlements and crop remains place established communities within Indian Ocean networks during the late first millennium CE: a 2016 archaeobotanical study identified Asian crops, including rice and mung bean, at sites in Madagascar and the Comoros. These finds provide material evidence for connections with Southeast Asia rather than a precise date for the island’s first occupation. (pmc.ncbi.nlm.nih.gov)

Austronesian-speaking migrants supplied the basic vocabulary and grammatical foundations of Malagasy, whose closest linguistic affinities include Ma’anyan and related languages of southeastern Borneo. This relationship does not mean that all Asian settlers belonged to a single present-day Bornean population. Migrants from East Africa, including Bantu-speaking groups, also contributed substantially to the population’s formation. A 2017 genetic study sampling 2,704 people from 257 villages found shared Bantu and Austronesian ancestry across Madagascar, with regional differences in their proportions. Linguistic ancestry and genetic ancestry therefore record related but distinct processes of migration and intermarriage. (nature.com)

Arab and Swahili commercial contacts linked the northern and northwestern coasts with the Comoros, East Africa and western Asia. Mahilaka, on Ampasindava Bay, developed around the tenth century into a major port; archaeological investigations have identified fortifications, imported goods, stone-bowl production and glass-bead manufacture. Its urban development resembled that of Swahili and Comorian towns. Islam spread through these maritime networks and coastal communities, rather than through the conversion of a unified island-wide state. Muslim settlements such as Mahilaka and, later, Kingany formed part of a changing network of ports connecting local production with overseas exchange. (doi.org)

From the seventeenth century, western Sakalava rulers built expansive kingdoms, notably Menabe and Boina. Their power depended partly on controlling overseas trade through Swahili and Indian intermediaries, with captives exchanged for firearms and other imports. On the eastern coast, Ratsimilaho captured Fénérive in 1712 and subsequently united coastal communities into the Betsimisaraka confederation. Demand for provisions and enslaved people from European settlements in the Mascarene Islands strengthened these eastern trading centres. Neither Sakalava nor Betsimisaraka political organization constituted a permanently unified government for Madagascar; the highlands contained competing principalities that subsequently became the base of Merina expansion. (onlinelibrary.wiley.com)

Andrianampoinimerina reunited the principalities of Imerina during the 1790s and continued expanding until his death in 1810. Rice cultivation, cattle, markets and captive labour underpinned the kingdom’s economy: improvements in rice production generated surpluses, while the crown sought direct control over trade routes and the exchange of captives for weapons. His son Radama I, who ruled from 1810 to 1828, extended this strategy toward coastal outlets; by 1825 Merina armies controlled much of the eastern littoral and had secured access to Mahajanga in the west. The British agreement of 1817, renewed in 1820, linked restrictions on slave exports to military, financial and technical assistance. It did not abolish domestic slavery, and warfare continued to supply captives. (assets.cambridge.org)

British connections also brought teachers and artisans. David Jones of the London Missionary Society arrived in 1818, established a school in Antananarivo in 1820, and helped develop the Latin-script orthography approved by Radama in 1823. Ranavalona I, who succeeded Radama in 1828, prohibited Christian practice and ordered missionaries to leave in 1835. Later French pressure restricted the monarchy’s diplomatic independence: the treaty of December 17, 1885 provided for a French resident to control foreign relations and imposed an indemnity of 10 million francs, while formally excluding interference in internal administration. On August 5, 1890, Britain recognized France’s claimed protectorate, substantially weakening the monarchy’s ability to balance the two European powers. (dacb.org)

Colonial conquest and rule

French conquest followed a decade of disagreement over the protectorate claimed by France under the 1885 treaty. Britain recognized that claim in 1890, but the Merina government continued to resist effective French control. In 1895, an expedition under General Jacques Duchesne advanced inland from Mahajanga and reached Antananarivo on 30 September, compelling Queen Ranavalona III to accept another protectorate treaty. Disease killed thousands of French expeditionary troops during the campaign. France formally declared Madagascar and its dependencies a colony by the law of 6 August 1896. General Joseph Gallieni, governor from 1896 to 1905, suppressed resistance and extended colonial administration beyond the former kingdom’s effective reach. In February 1897, he abolished the Merina monarchy and exiled Ranavalona III, initially to Réunion. Annexation thus preceded, rather than followed, the monarchy’s dissolution. (larousse.fr)

Colonial administration combined the abolition of slavery in 1896 with compulsory labour obligations. Gallieni extended the royal fanompoana system across the island in 1896–1897, requiring able-bodied Malagasy men aged 16–60 to provide fifty days of unpaid work annually. Labour requisitions supplied road construction and other public works, while settlers and concessionary enterprises also depended on coercive recruitment. In 1926, Governor-General Marcel Olivier instituted the Service de la main-d’œuvre des travaux d’intérêt général (SMOTIG), which selected workers from men not incorporated into military service. These arrangements transferred agricultural labour to colonial infrastructure projects and enterprises, often disrupting household cultivation. (maktaba.org)

Commercial policy favoured metropolitan interests: the annexation regulations admitted goods arriving directly from France or French colonies duty-free, while other foreign imports initially remained subject to a 10 per cent tariff. Agricultural and forestry concessions allocated extensive land to French settlers and companies, including fertile areas of the eastern coast and central highlands. Coffee, vanilla, cloves, sugar and other export products expanded through both plantations and Malagasy cultivation. Vanilla exports illustrate the change in scale: production was approximately one tonne in 1896, whereas annual exports averaged nearly 900 tonnes during 1929–1938. The Antananarivo–Toamasina railway, completed in 1913, and the Fianarantsoa–Manakara line, completed in 1936, connected producing regions to coastal outlets. (history.state.gov)

Land concessions, timber extraction and plantation expansion contributed to forest clearance. In some regions, the appropriation of fertile land and demands for plantation labour displaced cultivators toward forested slopes, linking commercial development with further clearance for subsistence farming. Conservation nevertheless became an early colonial administrative concern. The authorities treated forests as state property and restricted tavy, the clearing and burning of vegetation for cultivation, notably through the 1913 legislation. In 1927, they established ten strict nature reserves, including Andringitra. These protected areas were designed principally for scientific preservation and excluded ordinary resource use, creating a contrast between protection within selected boundaries and commercial exploitation elsewhere. (open.uapress.arizona.edu)

During the Second World War, Madagascar remained under Vichy authority until British operations in 1942. The campaign began with the seizure of the northern naval base at Diego-Suarez, now Antsiranana, in May. British forces subsequently landed at Mahajanga and advanced toward the capital in September; the King’s African Rifles participated in the inland operations. The British occupation did not terminate French colonial rule. An agreement signed with Charles de Gaulle’s French National Committee on 14 December 1942 preserved French sovereignty and provided for the transfer of civil administration from British to French hands. (history.state.gov)

After the war, Madagascar became a French overseas territory in 1946, while nationalist demands intensified. The Malagasy uprising began during the night of 29–30 March 1947 on the eastern side of the island. French repression included executions, arrests and the burning of villages; surviving military orders document attempts to restrict village destruction after the initial months. The authorities dissolved the Mouvement démocratique de la rénovation malgache (MDRM), founded in 1946, and prosecuted its leadership in 1948. Estimates of deaths vary substantially: figures approaching or exceeding 100,000 circulated in earlier accounts, while later archival studies produced much lower counts. The distinction between people killed directly and those who died from disease or deprivation during displacement is essential; the overall human losses are generally described as numbering tens of thousands. (larousse.fr)

Independence and the post-independence republics

Madagascar became independent on 26 June 1960 as the Malagasy Republic, with Philibert Tsiranana as president. His Social Democratic Party dominated the First Republic, while cooperation agreements preserved close connections with France in defence, finance, administration, and education. French military access included the naval base at Diégo-Suarez, and French personnel continued to provide technical and educational services. Independence therefore transferred political sovereignty without immediately dismantling the institutional and economic relationships established under colonial rule. (mjp.univ-perp.fr)

The First Republic ended amid student and labour unrest in 1972. Students demanded the replacement of French-oriented curricula with Malagasy teaching and wider access to secondary education; workers and public servants joined the movement. After security forces fired on demonstrators on 13 May, Tsiranana transferred full powers to General Gabriel Ramanantsoa on 18 May. An October referendum confirmed the military-led transition. Ramanantsoa revised relations with France but struggled with political and military divisions. He transferred power to Colonel Richard Ratsimandrava on 5 February 1975; Ratsimandrava was assassinated six days later. A military directorate subsequently selected Didier Ratsiraka as head of state, and the referendum of 21 December 1975 approved a socialist charter, a new constitution, and his presidency, inaugurating the Democratic Republic of Madagascar. (countrystudies.us)

Ratsiraka’s Second Republic combined nationalization, economic planning, and restricted political competition. His AREMA party dominated the National Front for the Defence of the Revolution: other parties existed, but electoral participation required membership in this front and acceptance of the socialist charter. It was thus a dominant-party system rather than a formally exclusive single-party state. State control expanded over banking, agriculture, and formerly French-held enterprises, while shortages and economic deterioration prompted a gradual shift towards market reforms supported by the International Monetary Fund. Political liberalization began in 1989, but strikes and mass protests intensified in 1991. Presidential guards fired on demonstrators approaching the presidential palace on 10 August. The agreement of 31 October established a power-sharing transition involving Ratsiraka and an opposition-led High State Authority headed by Albert Zafy. (countrystudies.us)

A new constitution was approved on 19 August 1992 by approximately 75 percent of participating voters. Zafy defeated Ratsiraka in the February 1993 presidential runoff with nearly 67 percent, becoming the first president of the Third Republic. His presidency ended through impeachment in 1996; Norbert Ratsirahonana served as interim president before Ratsiraka returned following that year’s election. The December 2001 contest between Ratsiraka and Antananarivo mayor Marc Ravalomanana produced rival claims to victory and parallel administrations in 2002. Ravalomanana claimed an outright first-round majority, while Ratsiraka insisted on a runoff. On 29 April, a High Constitutional Court recount awarded Ravalomanana 51.46 percent. Ratsiraka nevertheless continued to resist until July, when he left the country and Ravalomanana consolidated control. (countrystudies.us)

Ravalomanana was reelected in 2006, but conflict with Andry Rajoelina, elected mayor of Antananarivo in 2007, escalated after the government closed Rajoelina’s Viva television station in December 2008. Opposition demonstrations, lethal confrontations, and military defections followed. On 17 March 2009, Ravalomanana relinquished power to the military, which transferred authority to Rajoelina’s High Transitional Authority rather than following the constitutional succession procedure through the Senate president. The High Constitutional Court accepted the transfer, but the African Union treated it as an unconstitutional change of government and suspended Madagascar. Subsequent power-sharing negotiations repeatedly stalled over cabinet appointments, electoral arrangements, and Ravalomanana’s return from exile. (larousse.fr)

A November 2010 constitutional referendum established the Fourth Republic, although transitional rule continued. A September 2011 regional mediation roadmap eventually led to presidential and parliamentary elections in 2013. Hery Rajaonarimampianina, formerly Rajoelina’s finance minister, defeated Jean-Louis Robinson, supported by Ravalomanana, and took office on 25 January 2014. Rajoelina subsequently defeated Ravalomanana in the 2018 presidential runoff, returning through an election rather than a military-backed transfer. The November 2023 election again generated a political standoff: ten of the thirteen candidates called for a boycott, and the electoral commission reported turnout of 46.4 percent. Rajoelina won reelection amid the opposition boycott. (larousse.fr)

Political system and institutions

The Fourth Republic’s constitution, approved by referendum on 17 November 2010, established a semi-presidential system with a directly elected president, a prime minister and a bicameral legislature. The president is elected for five years, renewable once; an absolute majority is required, with a runoff between the two leading candidates if necessary. The constitutional framework must be distinguished from the transitional arrangements introduced after the military takeover of October 2025, which interrupted the normal operation of several institutions. (mjp.univ-perp.fr)

Executive authority is divided but not evenly balanced. The president chairs the Council of Ministers and determines the state’s general policy, while the prime minister directs its implementation and heads the administration. Article 54 requires the president to appoint a prime minister presented by the majority party or coalition in the National Assembly; other ministers are appointed on the prime minister’s proposal. Under Article 60, the president may dissolve the Assembly after consulting the prime minister and the presidents of both parliamentary chambers. Elections must then occur within 60–90 days, and another dissolution is prohibited for two years. The Assembly can remove the government through a motion of censure, but Article 103 requires signatures from half its members and approval by two-thirds, rather than a simple majority. (constituteproject.org)

Parliament consists of the National Assembly and the Senate. Deputies are directly elected for five-year terms. The election of 29 May 2024 filled 163 Assembly seats: Isika Rehetra Miaraka amin’i Andry Rajoelina (IRMAR), the presidential political grouping, won 84, while the opposition Firaisankina platform, led by former president Marc Ravalomanana, secured 22. Parties and coalitions therefore matter both for legislation and for the constitutional nomination of the prime minister. The Senate represents decentralized territorial authorities and economic and social organizations; the constitution allocates two-thirds of its membership to elected representatives distributed equally among the provinces and one-third to presidential appointees. It also gives the chamber a consultative role on decentralization and economic and social policy. (data.ipu.org)

The High Constitutional Court is separate from the Supreme Court within the judiciary. Its nine members serve non-renewable seven-year terms: three are appointed by the president, two elected by each parliamentary chamber, and two elected by the Superior Council of the Magistrature. It reviews legislation before promulgation, resolves institutional competence disputes, adjudicates presidential and parliamentary electoral disputes, and proclaims election and referendum results. Its decisions are binding and not subject to appeal. The Supreme Court instead comprises the Court of Cassation, the Council of State and the Court of Accounts, covering judicial, administrative and financial jurisdiction respectively. The Court of Accounts assists parliament and government in scrutinizing implementation of finance laws. (hcc.gov.mg)

The constitution recognizes provinces, regions and communes as decentralized territorial authorities. Legislation creating Ambatosoa in 2023 recorded six provinces, 24 regions and 1,695 communes. Ambatosoa combined the northeastern districts of Maroantsetra and Mananara Nord, with Maroantsetra as its capital. Constitutionally, regions coordinate economic and social development, territorial planning and development programmes; communes provide the framework for local administration and community services. The legal commitment to decentralization does not necessarily describe administrative practice: the constitution provides for elected regional heads, whereas regional governors have in practice been appointed by the central government. (cnlegis.gov.mg)

Disputes over prime-ministerial appointments illustrate the boundaries of institutional checks. In its decision of 11 February 2015 concerning the appointment of Jean Ravelonarivo, the High Constitutional Court held that the president’s appointment power under Article 54 was conditional, not discretionary: nomination by the Assembly majority was a prerequisite. Yet the same ruling described the prime minister as subordinate to the president within the executive and recognized presidential authority to dismiss the prime minister for serious fault or manifest failure. It thus identified a dual accountability—to the Assembly constitutionally and to the president in practice—within a system whose allocation of authority depends substantially on constitutional interpretation. (hcc.gov.mg)

The 2025–2026 political crisis and transition

Youth-led demonstrations began in Antananarivo on 25 September 2025 over recurrent electricity cuts and water shortages. Mobilized through social media under the name “Gen Z Madagascar,” protesters subsequently demanded President Andry Rajoelina’s resignation, raising concerns about living costs, employment opportunities and alleged corruption. Demonstrations spread to eight other major cities, according to the United Nations human rights office. Rajoelina dismissed Prime Minister Christian Ntsay and the cabinet on 29 September, but this did not end the protests. His subsequent invitation to dialogue was rejected by the youth movement. (time.com)

On 29 September, United Nations High Commissioner for Human Rights Volker Türk reported at least 22 deaths and more than 100 injuries during the unrest. The statement distinguished protesters and bystanders killed by security personnel from people killed during subsequent violence and looting by individuals and gangs unconnected with the demonstrators. It reported beatings, arrests, tear gas and some use of live ammunition, and called for independent investigations. The government disputed the figures: by 11 October, Reuters reported that Rajoelina had given a lower total of 12 deaths. These were competing accounts, rather than an agreed casualty count. (madagascar.un.org)

The decisive military intervention began on 11 October, when soldiers from CAPSAT, the army’s personnel and administrative services corps, joined demonstrators and announced that they would not obey orders to shoot protesters. Its commander, Colonel Michael Randrianirina, subsequently asserted control over the armed forces. On 13 October, Rajoelina publicly confirmed that he had left Madagascar, citing threats to his life. The following day, legislators proceeded with an impeachment vote despite his decree dissolving the National Assembly. Randrianirina then announced that the military had assumed state power and that a military council would govern during a transition before elections. (monitor.civicus.org)

Randrianirina was sworn in at the High Constitutional Court on 17 October 2025, following the court’s endorsement of the transfer of presidential authority. The new administration described its programme as the “Refoundation of the Republic” and initially promised elections within approximately two years. A mostly civilian cabinet announced on 28 October under Prime Minister Herintsalama Rajaonarivelo included 25 civilians and four military or paramilitary officers. Prominent Rajoelina opponents received portfolios: former National Assembly president Christine Razanamahasoa became foreign minister, and Fanirisoa Ernaivo became justice minister. On 9 March 2026, Randrianirina dismissed the prime minister and cabinet without publicly explaining the decision; on 15 March, he appointed anti-corruption official Mamitiana Rajaonarison as prime minister. (youtube.com)

The transitional leadership faced both supply problems and challenges through the courts. On 7 April 2026, the cabinet declared a nationwide energy emergency lasting 15 days, attributing disrupted supplies to the Middle East conflict. The declaration authorized exceptional measures to restore energy supplies and maintain public services, amid reports of widespread fuel shortages. On 28 May, the High Constitutional Court rejected deputy Antoine Rajerison’s application to remove Randrianirina and transfer presidential authority to another military leadership. It ruled the application procedurally inadmissible: an individual deputy’s petition did not satisfy the constitutional mechanisms for ending a head of state’s tenure, and the court’s October 2025 decision had created no separate removal procedure for the military authority. The ruling did not adjudicate the substantive allegations. (uk.marketscreener.com)

The electoral timetable remained a programme of future steps rather than a completed settlement. A roadmap submitted on 28 February 2026 envisaged consultations, constitutional reform and elections during a 24-month process. In a United Nations radio interview given on 24 September 2026, Randrianirina reaffirmed his commitment to an election in 2027. The programme envisaged a constitutional referendum or constitutional election between May and July 2027, followed by a presidential election before year-end. Preparatory questions included a revised electoral law and whether to modify or reorganize the Independent National Electoral Commission. Conclusions from political consultations were expected in November 2026, while the constitutional ballot also depended on the outcome of the broader national consultation process.

Economy and state finances

Agriculture is Madagascar’s principal source of employment, but its contribution to output is much smaller than its share of the workforce. The World Bank’s 2024 poverty assessment attributed approximately 70% of employment and 29% of gross domestic product to agriculture, reflecting the predominance of low-productivity subsistence farming. Rice is the staple crop: a World Bank assessment published in 2024 reported that it occupied about 1.3 million hectares and supplied roughly half of daily caloric intake. Domestic production is supplemented by imports, principally from India and Pakistan. Limited access to agricultural inputs, degraded irrigation infrastructure and weak water management constrain yields and farm incomes. (worldbank.org)

Export agriculture centres on vanilla, cloves and other spices. Vanilla production is concentrated in the northeastern SAVA region, where farmers’ access to collectors and export markets depends heavily on roads and bridges. Madagascar’s reported vanilla exports in the World Bank’s WITS trade database totalled approximately US$231.6 million and 4,544 tonnes in 2024; France and the United States were the largest destinations. Cloves, cinnamon and other agricultural products broaden the export base, but dependence on specialty commodities exposes earnings to international demand and price fluctuations. Preliminary central-bank figures indicated that total merchandise export earnings fell by 17.2% in 2024, with lower receipts from vanilla, cloves, nickel and other major exports. (blogs.worldbank.org)

Large-scale mining provides a separate export channel. Ambatovy began operations in 2012 and reached commercial production in January 2014. Its lateritic mine near Moramanga supplies a processing plant and refinery near Toamasina through a 220-kilometre slurry pipeline; refined nickel and cobalt are exported through Toamasina’s port. In the southeast, QIT Madagascar Minerals, a joint venture between Rio Tinto and the Malagasy government, extracts ilmenite near Fort Dauphin. Ilmenite is a source of titanium dioxide, used chiefly as a white pigment in paint and paper, and is shipped through the public deep-water port of Ehoala. (ambatovy.com)

The informal economy absorbs much of the workforce outside regular salaried employment. An International Labour Organization report, citing Madagascar’s 2013 national statistics, put informal employment at approximately 80% of the working population, particularly in agriculture and livestock. Small-scale, unregulated enterprises also provide irregular employment where formal job creation is insufficient. These livelihoods coexist with widespread poverty: the 2022 household survey placed 75.2% of the population below the national poverty line of 1,477,565 ariary per person annually. The corresponding rates were 79.9% in rural areas and 55.5% in urban areas; these figures use the national threshold rather than an international dollar-per-day measure. (ilo.org)

Limited revenue collection restricts state finances. The February 2025 economic update reported a tax-to-GDP ratio of 10.8%, identifying weak trade flows and generous tax exemptions as constraints on receipts; transfers and subsidies also crowded out capital investment. On 9 October 2026, the Ministry of Economy and Finance, headed by Aimé Herinjatovo Ramiarison, launched TOROHY through the Directorate-General of Taxes. The platform accepts reports of suspected tax fraud and corruption involving either tax officials or taxpayers, alongside feedback from users. Its stated purpose is to strengthen accountability and revenue mobilisation; the announcement described a reporting mechanism, not demonstrated reductions in corruption or tax losses. (documents1.worldbank.org)

Tourism generates foreign-exchange earnings and demand for accommodation, restaurants, transport and guiding. Ministry of Tourism figures reproduced by the World Bank recorded approximately 308,000 arrivals in 2024, up from 260,000 in 2023. Wildlife viewing in protected areas such as Ranomafana and coastal recreation around Nosy Be and Nosy Tanikely connect visitor expenditure to local businesses and households. Access infrastructure is a practical constraint: a transport project approved in April 2026 included safety, security and climate-resilience improvements at regional airports in Toamasina, Fort Dauphin and Tulear to maintain domestic connectivity and support tourism. (documents1.worldbank.org)

Population and society

Madagascar’s population was estimated at 32.7 million in 2025, with annual growth of approximately 2.4%. The May–June 2018 population census counted 25.67 million residents and recorded average annual growth of 3.01% between 1993 and 2018. Its median age was 18 years. UNFPA’s 2025 estimates placed 39% of the population below age 15 and only 3% at age 65 or older; people aged 10–24 accounted for 32%. The population remained predominantly rural: under the census classification, 80.7% lived in rural areas in 2018. Average household size was 4.2 people, ranging from 3.5 in Diana to 5.2 in Atsimo Atsinanana. (data.worldbank.org)

Population distribution is uneven, with major concentrations in the central highlands and selected coastal agricultural regions. Analamanga, which contains Antananarivo, held 14.1% of the national population in 2018 and had a density of 208.9 inhabitants per square kilometre, compared with 43.3 nationally. Antananarivo’s expansion involves substantial rural immigration and informal settlement: an estimate made by the International Organization for Migration in 2019 put rural-to-urban movement nationwide at more than 100,000 people annually, with the capital a principal destination. IOM’s 2024 assessment described 60–70% of new construction there as occurring in slum-like conditions, illustrating the gap between urbanization and the extension of serviced housing. (instat.mg)

Malagasy society is conventionally described as comprising 18 major ethnoregional groups, although these categories contain internal subdivisions and reflect histories of political consolidation as well as ancestry. The Merina are associated with the central highlands around Antananarivo, and the Betsileo with the southern highlands around Fianarantsoa. Betsimisaraka communities occupy much of the eastern coastal belt; Sakalava identities extend across western Madagascar; and the Antandroy are associated with the dry southern region around Ambovombe. These are not exclusively bounded populations: migration has established communities outside their ancestral regions. Anthropological accounts also distinguish Malagasy identity at the national level from these more localized affiliations, rather than treating the groups as separate national populations. (academic.oup.com)

Kinship connects households to ancestral places through descent, marriage, landholding, and collective burial. Among the Merina, affiliation with a family tomb can unite relatives living in different settlements, and kinship reckoning includes both maternal and paternal connections rather than following an exclusively paternal rule. Maurice Bloch’s Placing the Dead (1971) examined how tombs and ancestral villages organize these relationships. The famadihana ceremony may transfer remains to an ancestral tomb or involve reopening a tomb and renewing the shrouds of previously buried relatives. Contributions toward tomb maintenance and ceremonies sustain obligations among geographically dispersed kin. Descent can also preserve social hierarchy: Denis Regnier’s research among southern Betsileo communities documented avoidance of marriage with descendants of enslaved people, including families possessing land and ancestral tombs. Genealogical funeral speeches and investigations before marriage maintain knowledge of inherited status. These findings describe particular regional communities, not a uniform island-wide hierarchy. (doi.org)

Social inequality has a strong rural–urban dimension but is not confined to rural deprivation. The World Bank’s February 2024 poverty assessment found that 75.2% of residents lived below the national poverty line in 2022: 79.9% in rural areas and 55.5% in urban areas. Urban poverty had risen from 42.2% in 2012, with particularly pronounced deterioration in secondary cities. The assessment identified limited access to land, transport, electricity, water, sanitation, and education as constraints on household opportunities. A September 2024 World Bank account reported electricity access for approximately 30% of Malagasy people, with rural communities, poorer households, and female-headed households disproportionately excluded. (worldbank.org)

Internal migration includes seasonal livelihood movements and more permanent relocation from drought-affected southern districts. Menabe is one destination for households seeking agricultural land and livestock-based livelihoods outside the Great South. International migration includes study, employment, and family reunification; France is a principal destination, while Mauritius and Middle Eastern countries also receive Malagasy workers. An IOM assessment reported that more than 13,000 people had travelled to the Middle East and Mauritius through accredited employment agencies in the years covered by its 2016 reporting. Diaspora connections extend beyond remittances: more than 240 Malagasy associations were established in France during the decade preceding 2016, including organizations supporting education and health projects in Madagascar. (dtm.iom.int)

Language, religion, and cultural life

Malagasy belongs to the Austronesian language family and is closely related to Maanyan of southeastern Borneo. Regional varieties differ in pronunciation and vocabulary; standardized written Malagasy is based principally on the Merina variety of the central highlands. Its Latin-script orthography developed through cooperation between Radama I’s government and British missionaries during the 1820s. Malagasy serves everyday communication, broadcasting and religious life across the island, while French has important administrative, educational and commercial functions. Article 4 of the 2010 constitution names Malagasy and French as official languages. English is taught and used in international education and professional training but does not share that constitutional status. Malagasy and French coexist as teaching languages, with classroom code-switching between them; French is also widely used in business documentation. (countrystudies.us)

Christianity includes Roman Catholic, Reformed or Presbyterian, Lutheran and Anglican churches, alongside Adventist and evangelical communities. Islam is particularly established in northwestern and southeastern coastal areas, and most Muslims are Sunni. Religious affiliation does not necessarily exclude inherited practices: Christian or Muslim observance may coexist with ancestor veneration and Indigenous beliefs. The United States Department of State’s 2023 religious-freedom report explicitly notes this overlap and records substantially different demographic estimates from survey researchers and local religious organizations. Ancestors remain significant in family ceremonies and sacred places; the famadihana reburial rite, described elsewhere in this article, is one expression of that relationship. (ecoi.net)

Oral tradition places particular emphasis on indirect expression, proverbial knowledge and skilled public speaking. Kabary is structured, poeticized oratory incorporating proverbs, maxims, rhetorical figures and wordplay. Usually conducted as a dialogue between two speakers, or mpikabary, it accompanies weddings, funerals, official ceremonies and public gatherings. Elaborate performances can last several hours, whereas funeral speeches may use an abbreviated structure of about ten minutes. Formerly associated especially with older men, kabary is increasingly performed by women and younger speakers. Ohabolana, or proverbs, also inform hainteny, a form of poetry associated particularly with the Merina and characterized by metaphor and allusion. Jean Paulhan published Malagasy texts with French translations in Les Hain-teny merinas in 1913. (ich.unesco.org)

Instrumental traditions include the valiha, a plucked bamboo tube zither whose strings traditionally were raised from the bamboo’s outer surface; modern versions can use metal strings. Regional popular music includes salegy in northern Madagascar, represented by performers such as Eusèbe Jaojoby, and tsapiky in the southwest. Tsapiky combines fast-paced rhythms with electric guitars, drums, accordions and local instruments such as the small guitar-like kabosy and the marovany zither. Its songs address love, everyday life and social concerns, and its performances accompany weddings, funerals and festivals. Musicians commonly learn through listening, observation and participation in family, neighbourhood or professional ensembles. (metmuseum.org)

In the central highlands, hiragasy combines singing, dance and speech in public performances. A typical presentation involves two troupes and lasts approximately ninety minutes, proceeding through drumming, greetings, storytelling, dancing and folk songs. Its lyrics convey moral, civic and cultural themes. Historically used to communicate between rulers and their subjects, hiragasy later also provided a setting for expressing Christian faith outside church buildings. Transmission remains largely informal: children accompany performing parents on tours and gradually join their troupes. UNESCO inscribed kabary on its Representative List of the Intangible Cultural Heritage of Humanity in 2021, hiragasy in 2023 and tsapiky in 2025. Zafimaniry woodcrafting knowledge entered the list in 2008, following its proclamation in 2003. (ich.unesco.org)

The Royal Hill of Ambohimanga, inscribed on UNESCO’s World Heritage List in 2001, preserves a fortified royal settlement, burial places and a sacred landscape. Its complex includes fourteen fortified stone gateways, two palaces, sacred basins and royal tombs. Its cultural significance extends beyond surviving architecture: fountains, woods, sacrificial stones and royal trees remain associated with royal and ancestral traditions. Ambohimanga continues to function as a pilgrimage destination where visitors seek blessings, protection and spiritual renewal. (whc.unesco.org)

Health and education

Malaria transmission varies markedly across Madagascar: it is perennial along the humid eastern coast, seasonal in the west and north, and unstable and epidemic-prone in the central highlands and semi-arid south. Control programmes combine insecticide-treated nets, indoor spraying, rapid diagnostic tests and preventive treatment during pregnancy. Tuberculosis services face substantial geographical barriers despite a policy of free care; an initiative launched in rural southern Madagascar in September 2019 used community health workers and motorcycle-based mobile clinics to bring diagnosis and treatment closer to patients. (pmi.gov) Plague is endemic principally in the central highlands, but outbreaks can spread beyond these areas. Between 1 August and 22 November 2017, the Ministry of Health reported 2,348 confirmed, probable and suspected cases, including 202 deaths; 1,791 cases were classified as pneumonic plague. Unlike flea-associated bubonic plague, the pneumonic form permits person-to-person respiratory transmission, helping explain the outbreak’s spread into major cities and non-endemic districts. (iris.who.int)

Malnutrition compounds infectious-disease mortality. UNICEF’s country indicators recorded stunting in 39% of children under five in 2022 and wasting in 7% in 2021. The under-five mortality rate was 66 deaths per 1,000 live births in 2021, including a neonatal mortality rate of 24 per 1,000; the estimated maternal mortality ratio was 392 deaths per 100,000 live births in 2020. These indicators measure different outcomes and reference periods rather than a single annual snapshot. (data.unicef.org) UNICEF’s 2024 country programme identified particularly large caseloads of severe acute malnutrition in the Great South and increasingly in the southeast. It also reported that only 46% of births were attended by a qualified professional. Poor sanitation contributes to the burden of diarrhoeal disease: open defecation affected 54% of the rural population, compared with 24% in urban areas, while access to improved water sources remained incomplete. (unicef.org)

The health system links village-level community health workers to centres de santé de base (CSBs), district referral hospitals and higher-level regional and university hospitals. Rural CSBs provide the first level of facility-based care, but distance, staffing shortages and unreliable supplies constrain their use. Health-system strengthening in rural districts has therefore combined recruitment and training with medicine procurement, ambulance networks, community services and removal of user fees. (pmc.ncbi.nlm.nih.gov) The World Health Organization supports surveillance, emergency preparedness, maternal care and coordination of external assistance. A health-partner coordination platform established with WHO support brought together UNICEF, UNFPA, the World Bank, the Global Fund and Gavi; WHO also supported mobile clinics and personnel training following cyclones. (who.int)

General education comprises preschool, five years of primary schooling, four years of lower secondary schooling and three years of upper secondary schooling. Access does not necessarily translate into completion or literacy: a World Bank assessment published in 2025 estimated that 6% of primary-school-age children were not enrolled, while the 2019 PASEC assessment found that 83% of pupils at the end of primary school lacked basic reading competencies and 78% lacked basic numeracy competencies. Urban pupils and those attending private schools performed better than their rural and public-school counterparts. (documents1.worldbank.org) Remote schools rely heavily on parent-financed FRAM community teachers, many of whom lack adequate training. In 2024, the education ministry distributed Malagasy-language and mathematics textbooks to pupils in grades one and two and supplied teachers with lesson plans and in-service training in foundational reading and numeracy. (documents1.worldbank.org)

Higher education has expanded geographically and in participation. Provincial colleges initially attached to the University of Antananarivo became independent universities in 1982, extending the public system beyond the capital. (documents1.worldbank.org) UNESCO’s education-financing profile records an increase in the tertiary gross enrolment ratio from 2.02% in 2000 to 6.15% in 2022. This ratio counts students of all ages relative to the population of the corresponding tertiary-age group; it is not the proportion of all adults holding a degree. Public universities offer need-based scholarships, while private institutions provide an additional channel of access. (gem-report-education-profiles.unesco.org)

Infrastructure, energy, and transport

Madagascar’s road network is sparse and predominantly unpaved, making access to markets and public services sensitive to rainfall and cyclone damage. A 2023 World Bank assessment reported road density of only 5.4 km per 100 km²; just 11.4% of rural residents lived within 2 km of an all-season road, leaving approximately 17 million people outside that access threshold. The main corridors include RN2 between Antananarivo and Toamasina, RN7 through Antsirabe and Fianarantsoa to Toliara, and RN44 into the rice-producing Alaotra region. Road rehabilitation can substantially shorten journeys: improvements to 40 km of RN44 during 2020–2022 reduced travel between Marovoay and Vohidiala from eight hours to three. Flooding, landslides and bridge failures interrupt these corridors during the rainy season; a July 2025 financing package specifically supported replacement or rehabilitation of the cyclone-damaged Mahavavy and Ifasy bridges on RN6 and Manambery bridge on RN5a. (worldbank.org)

The limited railway network comprises two disconnected systems. The northern network links Antananarivo with Toamasina and includes branches toward Antsirabe and Lake Alaotra. The separate, approximately 163-km Fianarantsoa–Côte Est line connects Fianarantsoa with Manakara on the southeastern coast. Toamasina is the principal seaport and the coastal terminus of the country’s main capital–port transport corridor. In April 2026, the World Bank announced a project to rehabilitate key sections of the 371-km Tananarive–Côte Est railway and develop a rail–road dry port and logistics platform near Antananarivo. The same project included rehabilitation of port infrastructure at Mahajanga and Toliara, with measures intended to maintain year-round access and improve resistance to cyclones. (afdb.org)

Electricity supply combines hydropower with oil-fired thermal generation, but connections and reliable service remain limited. An International Monetary Fund study published in 2025 reported electricity access of approximately 36% in 2022. In 2023, national installed capacity totalled 718 MW: fossil-fuel plants accounted for 53%, hydropower for 33%, and solar installations for 14%. Installed capacity does not indicate actual generation or dependable output. JIRAMA, the state-owned water and electricity utility established in 1975, generated 1,953 GWh in 2023; the IMF described its production mix as approximately 54% heavy fuel oil and diesel, 45% hydropower, and 1% other renewables. Poor maintenance, inefficient fuel consumption, network losses and tariffs below costs weakened service and finances. Antananarivo experienced an average of six hours of outages daily in October 2024. Persistent electricity and water interruptions were the immediate grievances behind protests beginning on September 25, 2025. (imf.org)

Water infrastructure also displays a pronounced urban–rural divide. A 2022 World Bank project assessment reported access to at least basic water services for 85.8% of urban residents but only 36.3% of rural residents. Within JIRAMA’s water-service area, 69% of supplied customers depended on public standpipes rather than household connections. The $220 million National Water Project, signed in June 2022, provided for additional production capacity of 40,800 m³ daily in Greater Antananarivo and renewal of distribution networks to reduce losses. In the drought-prone south, groundwater supports domestic supply and livelihoods. UNICEF-backed multiple-use systems combine drinking-water, agricultural and livestock needs, with resource monitoring, protection of drinking-water quality and payments for operation and maintenance incorporated into their design. (documents1.worldbank.org)

Imported petroleum products supply both transport and thermal power plants, connecting electricity costs to overseas fuel procurement. Trade data for 2024 recorded refined-petroleum imports worth approximately $648 million from Oman and $125 million from the United Arab Emirates. The IMF identified high imported-fuel costs, alongside inefficient thermal generation, as important contributors to JIRAMA’s operating expenses. This dependence creates a transmission channel from fuel costs into electricity-production costs and the utility’s financing needs; road and bridge disruptions separately impede goods movements and can increase food prices in isolated communities. (wits.worldbank.org)

Environmental threats and conservation

Deforestation is driven by agricultural expansion, fuelwood and charcoal production, timber extraction, and livestock-related land clearance. Slash-and-burn cultivation, commonly called tavy, converts wooded land into fields, while logging removes commercially valuable trees even where the forest is not completely cleared. Grazing and repeated burning can inhibit woody regeneration. A 2018 study led by Ghislain Vieilledent, combining historical maps with satellite observations, estimated that natural forest declined from 16.0 million hectares in 1953 to 8.9 million hectares in 2014—a loss of 44%. Annual loss reached approximately 99,000 hectares in 2010–2014, and 46% of the remaining forest lay within 100 metres of an edge. These dated measurements are distinct from the frequently repeated claim that Madagascar has lost 90% of its “original” forest: reconstructing prehuman vegetation remains contested, and research on native grasses shows that not all open landscapes represent cleared forest. (documents1.worldbank.org)

Highland erosion includes the formation of lavaka, steep-sided gullies excavated into deeply weathered rock beneath a harder surface layer. Groundwater seepage, slope collapse, and storm runoff enlarge these features; vegetation clearance, roads, burning, and grazing can contribute locally. Their sediment enters rivers and accumulates in valley floors, floodplains, and coastal deltas, altering channels and aquatic habitats. However, lavaka existed before human settlement, and their recent dynamics are disputed. A 2022 Lake Alaotra study found substantially more newly formed than stabilized gullies and linked accelerating erosion partly to human pressure. A separate 2024 analysis found a declining proportion of highly active gullies despite increasing population and livestock density, emphasizing geological controls, including seismicity. Gully abundance alone therefore does not establish recent human-caused degradation. (sciencedirect.com)

Protected areas conserve forest blocks, watersheds, and habitats for endemic species, but legal designation does not eliminate agricultural encroachment, illegal timber harvesting, or wildlife hunting. The Rainforests of the Atsinanana, a UNESCO World Heritage property comprising six national parks, illustrates both these pressures and subsequent conservation measures. In 2010, UNESCO placed the property on its List of World Heritage in Danger amid illegal logging and hunting, particularly in Masoala and Marojejy national parks. It was removed from that list in July 2025 following conservation improvements. UNESCO described work linking forest protection with community water access and livelihoods, addressing conditions that had encouraged logging and agricultural clearance around parks such as Andohahela. (whc.unesco.org)

Tropical cyclones and floods produce episodic vegetation damage and sediment pulses, whereas prolonged drought places the south and southwest under sustained water stress. During the 2019–2020 and 2020–2021 rainy seasons, the Grand Sud received about 60% of normal rainfall. A World Weather Attribution analysis found no statistically significant human-induced increase in the probability of that particular rainfall deficit, distinguishing event attribution from longer-term projections. The World Bank’s 2024 climate assessment projected continued warming and greater rainfall variability, with fewer cyclone landfalls but more intense storms. For coastal ecosystems, rising sea temperatures increase coral-bleaching risks, while sea-level rise threatens mangroves and other low-lying habitats. (worldweatherattribution.org)

Conservation financing combines government institutions, international donors, and nongovernmental managers. The Madagascar Protected Areas and Biodiversity Fund, established in 2005, provides continuing financial support rather than relying exclusively on short project cycles. Its partners include Germany’s KfW, the French Development Agency, the World Bank, Conservation International, and WWF. In 2024, the fund reported annual financing for 70 protected areas covering approximately 6.04 million hectares; total protected-area support through its various mechanisms reached 33.75 billion ariary, reported as about US$7.59 million. Funding included regular grants, emergency assistance, equipment investment, and landscape conservation projects around Ankarafantsika and western baobab forests. (fapbm.org)

Community management also regulates resource use outside conventional state-run parks. At Andavadoaka in southwestern Madagascar, residents began a temporary octopus-fishing closure in 2004 with support from Blue Ventures and other partners. Increased catches after reopening encouraged neighbouring villages to adopt closures and establish the Velondriake community-managed marine area in 2006. Management combined temporary and permanent no-take zones, restrictions on destructive fishing, ecological monitoring, and dina, locally agreed customary rules. The approach tied conservation decisions to a measurable livelihood benefit while assigning enforcement and management responsibilities to a community association supported by technical partners. (blueventures.org)

Scientific exploration and research history

European contact with Madagascar began with the Portuguese navigator Diogo Dias in 1500, but detailed published descriptions of its natural history appeared considerably later. Étienne de Flacourt, governor of the French settlement at Fort Dauphin, now Tolagnaro, from 1648, assembled observations of animals, plants, and Malagasy society in Histoire de la grande isle Madagascar (1658). Its natural-history chapter described birds, fishes, and other animals alongside the island’s vegetation. These accounts preceded systematic specimen collecting and scientific classification; they represent an early European documentary record rather than the beginning of local knowledge of Madagascar’s environment. (en.wikisource.org)

Nineteenth-century exploration increasingly combined collecting, anatomical comparison, and geographical surveying. Alfred Grandidier first visited Madagascar in 1865 and continued his explorations until returning to France in 1870. His collections supported descriptions of living lemurs, reptiles, and birds, as well as investigations of extinct vertebrates. Working with the zoologist Alphonse Milne-Edwards, he published studies of sifakas, aye-aye nesting, and elephant-bird anatomy; their illustrated treatment of Madagascar’s birds contained 400 plates. His wider publishing enterprise, Histoire physique, naturelle et politique de Madagascar, brought together zoological and geographical documentation. Specimens retained in the Muséum national d’Histoire naturelle in Paris include material from Ambolisatra, the southwestern marsh deposit associated with his discovery of extinct hippopotamus remains. Such collections provided reference material through which later researchers could compare newly collected specimens with the originals used in naming species. (academie-sciences.fr)

Twentieth-century primate research added sustained observation of animals in their natural habitats to this collection-based tradition. In 1986, Patricia Wright and her research team located greater bamboo lemurs at Ranomafana and identified the golden bamboo lemur, previously unknown to science. Her subsequent work helped bring about the establishment of Ranomafana National Park in 1991. Research initially operated from tents and cabins, supporting studies of behaviour, ecology, and taxonomy. In 2003, Centre ValBio was established near the park, with Stony Brook University, the University of Helsinki, the University of Antananarivo, and the University of Fianarantsoa among its founders. The station institutionalized long-term fieldwork and training, while programmes linking landscape ecology, anthropology, and behavioural research examined how human resource use affected rainforest environments. (mariecolvincenter.org)

Research in paleontology reconstructed a substantially different recent fauna, including giant lemurs, elephant birds, hippopotamuses, and giant tortoises. Grandidier’s discoveries in the 1860s were followed by skull descriptions of Megaladapis, Palaeopropithecus, and Archaeolemur during 1903–1907. Later investigations combined radiocarbon dating with examination of bones for human modification: a 2005 study documented butchery marks on Palaeopropithecus ingens remains from Taolambiby. These findings established direct exploitation of giant lemurs, without by themselves demonstrating that hunting alone caused extinction. In 2019, Laurie Godfrey and colleagues proposed the “subsistence shift hypothesis,” connecting megafaunal collapse with expanding farming, herding, settlement, and human populations. This approach tested extinction mechanisms through the chronology of ecological and economic change rather than assuming an immediate disappearance after the first human arrival. (lemurs.linnaeus.naturalis.nl)

Modern molecular research has extended both historical reconstruction and the measurement of genetic diversity. A 2013 study led by George Perry analysed whole-genome sequences from 12 aye-ayes in northern, western, and eastern Madagascar, identifying pronounced differentiation of the northern population. In 2023, Alicia Grealy and colleagues recovered mitochondrial genomes from approximately 1,000-year-old elephant-bird eggshells, combining DNA with shell morphology, stable isotopes, and geographical provenance to identify a previously unrecognized northern lineage. A broader lemur study published online in December 2024 and in a January 2025 journal issue analysed 162 individuals representing 50 species. Its genomic reconstructions detected substantial declines in effective population size within the past 2,000 years, corresponding to human population expansion. These estimates concern genetically inferred breeding-population histories, not direct counts of animals alive at particular dates. (pubmed.ncbi.nlm.nih.gov)

Foreign relations and regional integration

Madagascar joined the United Nations on 20 September 1960, less than three months after independence. Its continental membership dates from 25 May 1963, when it became a founding member of the Organization of African Unity, the predecessor of the African Union (AU). UN agencies operating in Madagascar cooperate with the government, private sector, and civil society on development, humanitarian assistance, human rights, and peace and security. Continental participation is also subject to the AU’s rules against unconstitutional changes of government, which became directly consequential after the military takeover of October 2025. (madagascar.un.org)

Regional integration connects Madagascar to both mainland African markets and neighbouring island states. It joined the Southern African Development Community (SADC) in 2005 and participates in the Common Market for Eastern and Southern Africa (COMESA). Madagascar was among the initial participants in COMESA’s free-trade area, launched on 31 October 2000: participating states removed customs tariffs on qualifying goods originating within the bloc, rather than on all goods shipped through member countries. Madagascar, Mauritius, and Seychelles founded the Indian Ocean Commission (IOC) through the Port Louis Declaration of 21 December 1982; the Victoria Agreement institutionalized it in 1984. Comoros and France, representing Réunion, joined in 1986. IOC cooperation includes maritime security, fisheries, public health, ecosystem protection, and disaster-related environmental programmes. (sadc.int)

Relations with France combine French-language cultural connections, development assistance, commercial ties, and defence cooperation. Bilateral trade amounted to €984 million in 2024, when France was Madagascar’s third-largest export customer and third-largest supplier. French development assistance is channelled principally through the Agence Française de Développement, which authorized nearly €310 million in loans and grants during 2014–2018. Diplomatic engagement continued after the 2025 change of government: Emmanuel Macron met transitional president Michael Randrianirina in Paris on 24 February 2026, and cooperation projects worth approximately €70 million were announced. China is another substantial partner. Diplomatic relations began on 6 November 1972, and the relationship was designated a comprehensive strategic partnership in September 2024. According to China’s foreign ministry, bilateral trade reached approximately US$1.67 billion in 2025, principally Chinese exports of textiles, electronics, and machinery, and imports of Malagasy minerals and agricultural products. Investment-protection and joint economic-cooperation agreements provide additional institutional channels for the relationship. (diplomatie.gouv.fr)

The military seizure of power on 14 October 2025 prompted distinct institutional responses. On 15 October, the AU Peace and Security Council suspended Madagascar’s participation in all Union activities until constitutional order was restored; it demanded a civilian transitional government and credible elections, and warned that further military interference could trigger targeted sanctions. UN Secretary-General António Guterres condemned the unconstitutional change of government on 16 October while offering support for national efforts to address the causes of instability. SADC’s extraordinary Organ Troika summit that day offered mediation, authorized a fact-finding mission, and directed coordination with the AU, UN, and IOC. These measures combined exclusion from AU proceedings with continuing diplomatic engagement, rather than a uniform severance of international relations. (w.peaceau.org)

Maritime cooperation gives Madagascar an operational role beyond its domestic waters. A 2024 fisheries report submitted to the Indian Ocean Tuna Commission placed its exclusive economic zone at approximately 1.14 million square kilometres. Antananarivo hosts the Regional Maritime Information Fusion Centre, which exchanges maritime information and alerts the Seychelles-based Regional Coordination Operations Centre to abnormal activity; the latter coordinates joint operations at sea. Both centres formed core components of the EU-funded MASE regional security programme. Fisheries diplomacy also links access rights to financial and management support: the EU–Madagascar fisheries agreement and its 2023–2027 implementing protocol provisionally applied from 1 July 2023 and entered into force on 12 December 2023, providing an annual EU contribution of €1.8 million.
