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.

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.

The 26 December 2004 earthquake and tsunami devastated the lives of millions. With considerable determination, local communities have joined national and international organizations and governments to bring relief and start the recovery work. FAO has been involved in assisting the affected countries in numerous ways so that agricultural activities may be resumed. While short-term assistance is indispensable, strategic planning for medium and long-term rehabilitation in collaboration with partners and governments is required for appropriate intervention.
