Mangroves produce a number of very valuable ecological benefits. However, these benefits are largely intangible and do not provide income or revenue for the managers of the mangroves or for other stakeholders living in and around them. Therefore, they are often considered as “wasteland” rather than as highly prized ecosystems. In order to capture the interest and understanding of all stakeholders in and around mangroves, it is important to try to convert some of this intangible ecological value into a monetary value.

This report summarizes the findings of the e-mail conference that took place from 9 October to 4 November 2002 and which was organized by the Land Degradation Assessment in Drylands project (LADA). The report contains exchanges of views on data sets and methods that may be used to assess land degradation and a discussion on the biophysical, socio-economic and institutional indicators that explain the root causes, driving forces, status, impact and reponses to land degradation at various scales.

The Project was created as a result of an urgent need to protect cultivated land against the severe degradation caused by wind and water erosion in the Korqin Sandy Lands, to improve the socio-economic well being of the inhabitants of the region and for the need to sustainable produce wood for all sorts of uses.

Light textured sandy soils are ubiquitous throughout the tropics and constitute an important soil resource on which millions are dependent for their livelihoods. Spanning a range of rainfall regimes from the arid to the humid tropics, they present unique sustainability and environmental challenges to resource managers. Physical, chemical and biological characteristics of sandy soils often act as a severe limitation in crop production.

EPWS begins with the identification of a water problem (quantity and/or quality) downstream. this problem has significant financial impact for water users (domestic, industrial, commercial). causes of the problem are located upstream as a consequence of unsustainable land use (subsistence agriculture) by poor farmers who degrade the ecosystem.
