This module is about water resources, their complex relationship with the environment and the economy and the growing problem of water scarcity and the various options that exist to deal with this problem. The module examines how water is allocated between various competing demands and explores t...
This article presents an analysis of ERS-1 wind-scatterometer (WSC) data acquired over a region located in the northern Sahel. The considered period extends from January 1992 to December 1995, that is, covering four vegetation cycles. Experimental observations show that WSC responses at 45° of i...

Extensive areas of forest in the tropics have been legally classified as protected areas: however, in many cases it has been difficult to achieve their conservation. This paper argues that the priority for forest conservation should not be maximising the area totally protected but rather to focus...

Living on the edge: evaluating options for people and ecosystems at the forest edge.
This publication compiles and synthesises information on forest ecosystems with a view to transferring this knowledge to professionals and institutions involved in research and training. The chosen references provide an up-to-date picture of achievements in sustainable management of forest resour...
Tropical forest ecosystems represent a common heritage with livelihood portfolios shared by a great majority of people especially in developing countries but are now threatened by climate change. In spite of their contribution to poverty alleviation and food security, and also for climate change ...
