Abstract
Though it has been widely asserted that recent deforestation in the Gran Sa bana is a result of intensified shifting cultivation, no supporting communi ty-specific data oil rates of vegetation and land use changes has previousl y been provided. Mapping of vegetation and land use in Kavanayen, the large st indigenous community in the Gran Sabana, and comparison with similar ear lier data, indicate that in areas of intensive cultivation there has in fac t been substantial forest loss and deflection to secondary none forest vege tation. The deforestation in these valleys is directly associated with inte nsive agriculture and abbreviation of the fallow period and indirectly with the increasing use of fire that accompanies cultivation and the increase i n combustible secondary vegetation. Changes in the indigenous culture, name ly; increases in population size and density and, for sonic cultivators, ch anges in agricultural site selection characteristics that now emphasize log istical as opposed to the more traditional environmental factors, are intim ately connected with the more to more spatially and temporally intensified cultivation arid the resultant deforestation in the fallow period.
