Develop a good Comparative Risk Assessment (CRA) Methodology.

Grand challenge: Develop a good Comparative Risk Assessment (CRA) Methodology. CRA provides a systematic way of looking at environmental problems that pose different types and degrees of health risk. It combines information on the inherent hazards of pollutants, exposure levels, and population characteristics to predict the resulting health effects. Using data from available sources, rapid, inexpensive comparative risk assessments can identify the most significant health problems. Together with consideration of costs, technical feasibility, and other factors, the results of comparative risk assessment can be used to set priorities for environmental management. Thus, Comparative risk assessment provides a general

framework for evaluating environmental problems that affect human health,

In the past USAD has completed CRAs in Cairo ,Egypt; La Paz, Bolivia; the Caspian Sea; Bangkok, Thailand; and Lima, Peru -among others.

This experience combined with a new awareness would allow USAID to develop a streamlined approach to CRAs that can quickly offer field assessments of the impacts of various environmental problems.
