It may come as a paradox that while interest in tropical forests worldwide has been steadily growing in the last century, this has in no way halted the continued loss and degradation of one of earth's grandest terrestrial ecosystems. In fact, the extent and rate of degradation is accelerating. Some places have completely lost their original forests, while in others the structure and biomass of the forest have been irreparably damaged. Concern for this loss is not limited to the extinction of animal and plant species.

FAO Investment Centre environmental reports are directed to environment and natural resources specialists. They address environmental issues associated with the formulation of investment projects for the agricultural/rural sector. This report describes an environmental assessment that contributed to improvements in the project design for the Aberdares Natural Resources Development Project in Kenya. The objective of this six-year project was to conserve and develop the natural resources of the Aberdares region based on an integrated management approach involving local communities.

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.
