ABSTRACT

In the context of climate change and ecological disruptions, this study focuses on the diagnosis of the changes taking place in the microtidal environment of the Southeast lagoon ecosystems of Togo. To do this, a diachronic analysis of soil classification occupation of two Land sat satellite images (TM and ETM 1986 to 2011) was performed with ground verification. This analysis on two dates revealed the successive states to characterize the main environmental changes that have affected the lagoon ecosystems. The results revealed significant changes both natural and anthropogenic who achieved water resources and their buffer zones, plant cover and the frame of the study area. During 25 years, terrestrial vegetation around wetlands decreased by 26.28% and aquatic plants showed a surface increase of 13.2%. This study is a knowledge contribution to the lagoon ecosystems state in Togo through an ecological analysis which reveals some environmental changes in order to anticipate the loss of ecosystem goods and services of these wetlands.
