Global climatic change, water resources, and food security

Gleick, P.H.
Alterations in climate due to increasing atmospheric concentrations of carbon dioxide and other trace gases must be viewed with concern, if not alarm, because of the risk of adverse impacts on the availability and quality of water resources. Hydrologic changes may lead to alterations in pressure on food resources in many regions of the world. This paper explores the mechanisms by which food security - defined here as the ability of a region to produce or otherwise provide food without threatening the well-being of either the population or the existing political systems - could be affected by climate-induced changes in water resources. Shifts in the timing, magnitude, or location of major hydrologic phenomena, such as runoff, soil moisture, or monsoons, are discussed, together with the important vulnerabilities of agricultural productivity to changes in water availability. Some of the concomitant political and socioeconomic implications are also presented, with suggestions for ways to enhance the reliability of food resources dependent on uncertain water supplies.

Abstract: This report addresses issues related to public concern about the safety of continued reliance on pesticides in agricultural production. Topics discussed include: the lack of understanding of how food is grown; the role of pesticides in food production; the risk assessment, regulating processes, and alternatives to pesticide use; and the limits on citizen participation in food safety debates and agricultural decision making. This publication was produced for individual citizens and organizations concerned about agriculture and food safety and interested in raising their community's awareness of the topic.
