An Assessment of Climate Change, Water Resources, and Policy Research
A significant climate change can affect water resources and result in social and/or environmental impacts that can become policy issues. Review of the research in this emerging field of climate, water and policy reveals certain key issues that affect the transfer of information to policymakers. It also reveals the necessity for interdisciplinary analyses, a lack of information about parts of the hydrologic cycle, and the limited views many hydrologists have about climate changes and how to deal with them. The emphasis of recent research has been on effects on precipitation of CO, induced global warming on how climate changes might alter extreme events (droughts and floods), the relationship of climate alterations and water quality, and development of methods to better ascertain linkages of climate, water, and society. Policymakers attempting to address the effects of climate change on water resources generally ask six questions including: (1) the type of climate change apt to occur; 2) the changes beyond our recent (100-year) experience; 3) whether the changes can be predicted; 4) the certainty of change/s predicted; 5) the effects (social and environmental) that will occur; and (6) the potential adjustments needed.
Efforts to address adequately these questions are often hindered by four problem areas that need attention. First, climate impacts research is still in the developmental stage. Second, knowledge about certain hydrologic cycle variables is lacking and in particular, the interactions between climate and water quality. Third, many hydrologists assume stationarity in climate and find it difficult to accept and utilize climate change concepts. Finally, the impact of information on climate-water issues on the policy process is less than adequate often because scientists poorly understand the policy process.
