"Deforestation rates and land-use changes related to environmental factors (slope angle and soil type), in addition to some local population and economic attributes, were estimated from Landsat MSS satellite images of two municipalities of different sizes and for a greater portion of the highlands of Chiapas, Mexico. Annual deforestation rates for 1974-84 and 1984-90 were 1.58 and 2.13%, respectively, in the central highlands of Chiapas; 1.84 and 1.10% in the highly populated Huistan; and 0.46 and 3.42% in the relatively unpopulated Chanal.
