    Modeling of crop supply frequently adopts separate treatment of area and yield variables. The advantage of this approach is that it conveniently imposes the property of land being a quasi-fixed factor, at least on the aggregate. Given an agricultural land frontier, total supply of land may be fixed in the short run. Various crop multi-market models either ignore this property, thus foregoing the advantage of the area x yield formulation, or impose the aggregate land constraint in an ad hoc fashion.

    Afrique sub-saharienne

    Water, food and energy are fundamental to African development. However, several crucial issues need to be addressed. Are African resources used to meet African needs or are they being exploited to satisfy the needs of other actors facing food and energy insecurity?

    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.

    The Climate Action Tracker (CAT) compares and assesses national and global action against a range of different climate targets across all relevant time frames. This report assesses whether Mexico’s current policies and climate action pledges meet the country's targets and approach the targets required for a global 2°C or lower pathway. According to the report, Mexico is among the countries most advanced in reducing emissions from deforestation and ensuring afforestation through payment for environmental services.

    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.

    Nicaragua, Amérique latine et Caraïbes

    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.

    The core thesis is that Western neoclassical economics and law (particularly Anglo-American) have a peculiar cultural history that biases Western-trained economists and lawyers against common property systems like those found among Africans and American Indians. This Western cultural bias is expressed through the recurrent focus on individuals as atomistic and independent of each other in contract and property law, as well as in economic theory.

    Éthiopie, Afrique sub-saharienne

    There is a common view and belief that women are the ones that do the farming in Africa while the men do not work much. This paper seeks to find explanations to why land productivity is lower on land rented out by female landlord households than on land rented out by male landlord households in the Ethiopian highlands. The authors find that female landlords have tenants who are older, own less oxen, are more related, and under longer-term contracts.

    This report argues that land reform, both tenancy reform and redistribution of ceiling surplus lands to the landless, is important to poverty alleviation.The paper argues that in addition to production benefits, land reform helps to change the local political structure by giving more voice to the poor. Re-distributive land reform, whether through market-assisted land reform programmes or otherwise, should remain a substantive policy issue for poverty reduction.
