Literature review, focusing on recent and contemporary tenancy structures in Asia, Africa, and Latin America. Tenancy for purposes of this review is broadly defined to include different leasing arrangements such sharecropping, labor tenancy, fixed cash rentals, and reverse leasing. Authors have limited our discussion to private leasing of agricultural land, thereby ignoring issues pertaining to leasing of public, forest, and other noncrop lands.

Synthesizes the results of more than 140 economic models analyzing the causes of tropical deforestation. Raises significant doubts about many conventional hypotheses in the debate about deforestation. More roads, higher agricultural prices, lower wages, and a shortage of off-farm employment generally lead to more deforestation. How technical change, agricultural input prices, household income levels, and tenure security affect deforestation—if at all—is unknown.

Land and forestry-based activities could in principle play important roles as climate change mitigation strategies. In practice, however, several questions have been raised about their feasibility. Therefore, understanding the processes and determinants of land use changes is critical. This paper aims to contribute to such understanding in the larger part of a larger project on sustainable development and economic growth. It begins with a dynamic model of land use.

The advance of the agricultural frontier constitutes the biggest source of deforestation in Central America today. This conversion of tropical forests into agricultural land and pasture is the direct result of individual land use decisions. This paper presents a simple analytical model of household land use, followed by an econometric analysis of household survey data from the Río San Juan region of Nicaragua in order to test for consistency with the model.
