Environmental managers need current, accurate information upon which to base decisions. Viable information, especially in developing countries, is often unavailable. Satellite remote sensing is an appropriate and effective data source for mapping the surface of the earth including a variety of environmental features. Remote sensing derived information is enhanced by being one component within a Geographic Information System (GIS). These techniques were employed to study an expanding delta in East Africa. The Omo River flows from the Ethiopian Highlands into the northern end of Lake Turkana creating a large delta extending between Ethiopia and Kenya. This isolated and unique wetland feature has expanded by over 500 sq. km in the last fifteen years as measured by spaceborne remote sensing techniques and corroborated by low altitude aircraft reconnaissance flights. The growth of the delta appears to be a function of both increased sedimentation and decreased lake levels and river flows. Within the delta there has been a selective decline in wildlife and an increase in human activity, both pastoral and agricultural. The uniqueness of this isolated delta suggests that consideration be given to its possible protection and management.
