The main causes of deforestation of the Amazon rainforest are human settlement and development of the land. In the nine years from 1991 to 2000, the area of Amazon rainforest cleared rose from 415,000 to 587,000 km 2 (160,000 to 227,000 sq mi), comparable to the total land area of Spain, Madagascar or Manitoba.n the nine years from 1991 to 2000, the area of Amazon rainforest cleared rose from 415,000 to 587,000 km 2 (160,000 to 227,000 sq mi), comparable to the total land area of Spain, Madagascar or Manitoba.
Forest degradation and loss from the spontaneous expansion of people's activities into forest lands is notoriously difficult to quantify. Shifting agriculture is the primary cause of deforestation, accounting for about 45 per cent of the 7.5 million ha losses in tropical forests in 1976-1980. In 1980 it accounted for 35 per cent of deforestation in Latin America, 70 per cent in Africa, and 49 per cent in South-East Asia (notably Sri Lanka, Thailand, north-east India, Laos, Malaysia, and the Philippines) (Tolba et al., 1992).
