Management of watersheds with Landsat TM data: a case study of the Volta River in Ghana

Notwithstanding the huge national achievement of Ghana supplying the main focus of its independence in the early years, the Volta River Project continues to have many negative consequences which impact large parts of the country. Remote sensing methods are introduced to show how information about these impacts may be obtained and used in sensible management programs. The monitoring literature suggests that a surprising range of relevant and remotely sensed information may be provided. In this study, this information is discussed and evaluated for its significance and its potential value for the evolution of Ghanaian policy.
