Agriculture in the dry savannas is intensifying in response to increasing populations of humans and livestock. As a result, increased productivity demands are placed upon integrated crop-livestock systems and more emphasis is on the roles of legumes such as cowpea. Cowpea has the potential to fun...

Bolivia's structural adjustment policies, initiated in 1985, increased poverty among certain groups, but this did not lead to widespread migration to the agricultural frontier. Nor did adjustment greatly affect the average area planted in annual crops by small lowland farmers. Structural adjustme...

Special section: land use options in dry tropical woodland ecosystems in Zimbabwe: introduction, overview and synthesis
Despite considerable international attention in the field of forest conservation, tropical forests are still disappearing at an unaltered pace. This book gives an economic perspective on the analysis of deforestation. Following a survey of different deforestation definitions, theories and empiric...

The main challenge that the Amazon region poses is what should be done to avoid that the region will follow the fate of other tropical regions: forest destruction and poverty. The fact that most of 80 percent of the region remains as forest leaves us the opportunity to build the way towards susta...

That forest people intimately depend on forests for their livelihoods is widely accepted and, so it is predicted, the rapid pace of deforestation in the humid tropics will soon lead them into utter destitution or, worse, drive them into cities. Socio-economic studies recently carried out among Pu...
