This paper examines the causes of agricultural land expansion and deforetstion in Tanzania. In the theoretical section, two different -- and partly contradicting -- sets of hypotheses are outlined. These are based on a subsistence approach, emphasising the food or income requirements of farm hous...

Economic theory and empirical evidence suggest that building or improving roads near forests encourage forest clearing for land speculation, agriculture and other activities. Policies used to mitigate the dangers of forest road projects have failed in many countries. Practically all countries now...

Indonesia is among the world's leading wood products exporters, and is the leading plywood exporter. The forest sector has grown rapidly in the last three decades to 487 concessions occupying 56 million hectares. A notable change in recent years has been the rapid growth of the pulp and paper ind...

The objective of this study is to better understand the complexity of deforestation processes in southern Cameroon by testing a multivariate, spatial model of land-cover change trajectories associated with deforestation. The spatial model integrates a spectrum of independent variables that charac...

The rate of forest clearing by small farmers in the humid forest zone (HFZ) of Cameroon increased significantly in a period of economic crisis dating from 1986. A random sample survey of 648 households was conducted in 54 villages in the HFZ to understand the effect of the crisis and of a 1996 cu...

Popular concern about tropical deforestation largely drove the rapid growth in forestry assistance in recent years. Nevertheless, forestry assistance has had limited impact on forest clearing and much of it has gone to address other problems. To reduce inappropriate deforestation requires a combi...

This chapter attempts to systematically examine some of the main analytical arguments and empirical evidence regarding the impact of technological progress in agriculture on deforestation. Three factors have been highlighted that are important in determining deforestation outcomes: (1) the type o...

This chapter spells out the theoretical framework for the discussion and case studies of the book. First, it provides precise definitions of technological change and classify technological change into different types based on their factor intensities. The discussion starts off with a single farm ...

What policy lessons derive from the half-century of banana expansion in the coastal region? For that whole period bananas had a catalytic role in promoting coastal deforestation. At first, this was mostly through direct banana frontier expansion. Later the gradual settlement effects proved key. M...
