The Impact of Climatic Variations on Agriculture: Volume 2: Assessments in Semi-Arid Regions

Review `It is an admirable book in its breadth and depth. It is authoritative, up-to-date, extensively referenced and illustrated. There are many tables of data ... Put it high on your list of recommendations for library purchase.' E. Linacre, Australian Geographer, November 1989 `... this is a book which should be read by all planners and policy makers as well as agricultural scientists who are endeavouring to have a complete knowledge of their subject.' W.J. Ridgman, Journal of Agricultural Science, Vol. 113, 1989 `In addition this volume contains a lot of data about climatic and other site factors influencing biomass production as well as about economic conditions in the different regions. Together with volume 2 this volume provides an important basis for ecologists as well as for economists for studying the interaction between climate and plant growth and biomass production in the different regions of the world.' Agroforestry Systems, 10, 1990 Product Description Three important studies were initiated in the 19708 to investigate the relation­ ship between climatic variations and agriculture: by the National Defense University (1980) on Crop Yields and Climate Change to the Year eooo, by the U.s. Department of Transportation (1975) on Impacts 0/ Climatic Change on the Biosphere and by the U.s. Department of Energy (1980) on Environmental and Societal Consequences 0/ a Possible CO -Induced Climatic Change (the ClAP 2 study). These were pioneering projects in a young field. Their emphasis was on measuring likely impacts of climatic variations rather than on evaluating possible responses, and they focused on first-order impacts (e.g., on crop yields) rather than on higher-order effects on society. A logical next step was to look at higher-order effects and potential responses, as part of a more integrated approach to impact assessment. This was undertaken by the World Climate Impact Program (WCIF), which is directed by the United Nations Environment Program (UNEP). The WCIF is one of four aspects of the World Ciimate Program, which was initiated in 1979.
