Population distribution:
most of population lives on the eastern half of the island; significant clustering is found in the central highlands and eastern coastline

Natural hazards:
periodic cyclones; drought; and locust infestation

volcanism: Madagascar's volcanoes have not erupted in historical times

Environment - current issues:
erosion and soil degredation results from deforestation and overgrazing; desertification; agricultural fires; surface water contaminated with raw sewage and other organic wastes; wildlife preservation (endangered species of flora and fauna unique to the island)

Environment - international agreements:
party to: Biodiversity, Climate Change, Climate Change-Kyoto Protocol, Desertification, Endangered Species, Hazardous Wastes, Law of the Sea, Marine Life Conservation, Ozone Layer Protection, Ship Pollution, Wetlands
signed, but not ratified: none of the selected agreements

Geography - note:
world's fourth-largest island; strategic location along Mozambique Channel; despite Madagascar’s close proximity to the African continent, ocean currents isolate the island resulting in high rates of endemic plant and animal species; approximately 90% of the flora and fauna on the island are found nowhere else
