Abstract

The present study aims at assessing consequences of salinization during the last three decades in this estuary with regard to land, biodiversity and water degradation. In this respect, Landsat images (1984, 1992, 1999 and 2010) were used to investigate regional time series land use/land cover. These were classified into eight land-use/land-cover types: water bodies, high mangrove, low mangrove, denuded and salty soils (locally called "Tan"), savannah, rainfed agriculture, forestland and urban or built-up land. Change detection analysis of land and mangrove degradation was assessed using GIS techniques. Spectral analysis indicated that from 1984 to 2010, low and high mangroves, rainfed agriculture and savannah are converted to "tan" (denuded and salty soils).
