PrefaceHuman beings have a powerful effect on the environment, as is becoming increasingly clear. Demographic factors are commonly recognized as one of the primary global drivers of human-induced environmental change, along with biophysical, economic, sociopolitical, technological, and cultural factors. Concerns about demographic effects on the environment are fueled by demographic trends such as global population growth and the exponential growth of urban areas. These trends have spawned a body of literature regarding the connections between demographic trends and natural resources, such as water, much of which has taken an alarmist view. The reports often limit themselves to looking at the effects of population growth, and treat water supplies as static and population as ever increasing, inexorably leading to a crisis of water availability. This monograph attempts to present a more holistic view of the interaction between demographic factors and water resources by considering a wider range of demographic variables as well as a set of mitigating factors that influence the availability of water at the local level. The monograph focuses primarily on conditions in developing countries, since that is where the forces of demographics and natural resources intersect with the fewest social and economic resources to mediate their impacts. This monograph should be of interest to anyone concerned with the interaction between demographic issues and water and other environmental issues, including policymakers and academics.The funding for this project was provided by a grant to the RAND Corporation from the Compton Foundation. This research iv Liquid Assets was conducted for Population Matters, a RAND project to synthesize and communicate the policy-relevant results of demographic research. Through publications and outreach activities, the project aims to raise awareness and highlight the importance of population policy issues and to provide a scientific basis for public debate over population policy questions.The Population Matters project is being conducted within RAND Labor and Population, a program of the RAND Corporation.For further information on the Population Matters project, contact Julie DaVanzo Population Matters RAND
