Located in semi-arid zone, oasis basins of east-central Niger are high potential agroecosystems. They represent the last areas where farming is possible throughout the year. These oasis basins have experienced many investments from several NGOs and projects in these recent years.

This thesis aims to: • Evaluate the performance of three image classification methods in detecting these oasian basins in the Department of Goure. The methods are pixel analysis, textural analysis and object analysis. They are applied to SPOT 5-THX 2.5 m resolution images. • Characterize the oasis basins shape with t...
