In the Amazon basin, few studies have focused on environmentally sound
land-use alternatives that are linked to markets. This paper analyzes
land uses carried out by traditional inhabitants (ribeirinhos) on thr
ee islands in the Amazon estuary. Management of the native floodplain
forest is the most extensive form of land use on these islands. Such m
anagement varies in response to local economic and ecological conditio
ns but invariably targets key nontimber forest resources destined for
local markets, requires minimal input of labor and capital, and mainta
ins a considerable stock of biotic resources. While restricted to a sp
ecific forest type, this form of land use is associated with relativel
y high population densities and, if supported by appropriate developme
nt policies, could provide an environmentally sound land-use alternati
ve for hundreds of thousands of rural inhabitants of Amazonia.
