This report has been prepared in response to growing concerns about the impacts of climate change on Latin American economies, agriculture, and people. Findings suggest that because of the climate change impacts on agricultural production (yield change) and international food prices, unless...

Water plays a major role in the climate system and in mediating impacts of climate variability and change on all sectors of the economy. The incorporation of water resources modeling into integrated assessment models (IAMs) to study climate–hydrology processes, related water impacts and...

The world population is expected to grow to 7.7 billion in 2020, from 5.3 billion in 1993 (UN, 1996). Although the latest population projections represent a slowdown from past estimates, the large absolute increase in population raises serious concerns about how food demand will be met in the...

Two possible adaptation options to climate change for Sub-Saharan Africa are analyzed under the SRES B2 scenario. The first scenario doubles irrigated areas in Sub-Saharan Africa by 2050, compared to the baseline, but keeps total crop area constant. The second scenario increases both rainfed and...

Substitution of irrigation water with other agricultural inputs could be an important means to conserve water in the face of growing pressures on water resources from both nonagricultural water demands and environmental water requirements. This paper discusses the potential of such substitution...

Approximately 80 percent of poor people in Sub-Saharan Africa continue to depend on the agricultural sector for their livelihoods, but-unlike in other regions of the world-agriculture in Sub-Saharan Africa is characterized by very low yields due to agroecological features, poor access to...
