Abstract

Whenever disaster threatens, and large numbers of people are put at risk, the availability of drinking water is crucial. But safe water is rare in most of Africa. Limited development of potential sources of safe supplies, and inadequate distribution systems are the problem. Several operational satellite systems provide image data that are useful for efficient water exploration. Except for the humid tropics, cloud-free data are available for most of Africa. Remote-sensing missions, notable the Landsat Thematic Mapper, and ASTER, are specifically designed to reveal soil- and rock-related information, which Earth scientists can use to assess potential water resources and suggest the best sites for extraction, storage and distribution. In this way timely, reliable information can be provided during disasters and preventative measures taken.
