Effects of Climate Change on Global Food Production from SRES Emissions and Socioeconomic Scenarios
Entry ID: CIESIN_SEDAC_MVA_ECCGFPSRES


Summary
Abstract: Effects of Climate Change on Global Food Production from SRES Emissions and Socioeconomic

Scenarios is an update to a major crop modeling study by

the NASA Goddard Institute for Space Studies (GISS). The initial study was published in 1997, based on output of HadCM2 model forced

with greenhouse gas concentration from the IS95

emission scenarios in 1997. Results of the initial study are presented at SEDAC's Potential Impacts of Climate Change on World Food

Supply: Data Sets from a Major Crop Modeling Study,

released in 2001. The co-authors developed and tested a method for investigating the spatial implications of climate change on crop

production. The Decision Support System for

Agrotechnology Transfer (DSSAT) dynamic process crop growth models, are specified and validated for one hundred and twenty seven

sites in the major world agricultural regions. Results

from the crop models, calibrated and validated in the major crop-growing regions, are then used to test functional forms describing

the response of yield changes in the climate and

environmental conditions. This updated version is based on HadCM3 model output along with GHG concentrations from the Special Report

on Emissions Scenarios (SRES). The crop yield

estimates incorporate some major improvements: 1) consistent crop simulation methodology and climate change scenarios; 2) weighting

of model site results by contribution to regional and

national, and rainfed and irrigated production; 3) quantitative foundation for estimation of physiological CO2 effects on crop

yields; 4) Adaptation is explicitly considered; and 5)

results are reported by country rather than by Basic Linked System region. The data are produced by A. Iglesias and C. Rosenzweig and

the maps are produced by the Columbia University

Center for International Earth Science Information Network (CIESIN).


Purpose: To provide an assessment of potential climate change impacts on world crop

production.
