| Abstract: | The underlying causes of forest area variation were studied by using data from the original forest assessments between 1970 and 1991 of FAO FORIS database representing 477 subnational geographical units in 67 tropical countries. Multiple regression modelling was applied to measure the effects. Five ecological variables were used to control the varying ecological conditions in the subnational units. Three variables were used to control the varying reliability of forest inventory data. Population and income variables were found to be significant factors explaining forest area variation after controlling for ecological variation. In particular population density and income per capita turned out to be significant underlying factors of deforestation. The overall conclusion is that determining the factors behind forest area variation helps explaining the causes of deforestation. |
