SEDAC Goddard Institute for Space Studies Crop-Climate Database Query

Project Description
In an effort to better understand the potential global impacts of climate
change on agriculture, in 1990 the U.S. Environmental Protection Agency
contracted the Goddard Institute for Space Studies to coordinate a major study
of the effects of changing temperature and precipitation regimes and increased
CO2 concentrations on crop production and its economic implications. The
central aim of the study was to provide an assessment of potential climate
change impacts on world crop production, including quantitative estimates of
yield changes of major food, cash and industrial crops, prices, trade and risk
of hunger. Agricultural scientists from 18 countries estimated potential
changes in crop growth and production at 125 key agricultural sites using
compatible crop models and consistent climate change scenarios. The study
assessed the implications of climate change for world crop yields taking into
account uncertainty in the level of climate change expected, physiological
effects of CO2 on plant growth, and different adaptive responses. Projected
yields at the agricultural sites were then aggregated to major trading regions,
and fed into a global trade model (the Basic Linked System or BLS) in order to
produce regional estimates of potential price increases, food shortages, and
risk of hunger.
