The study was caried out in Peru in 2003 and 2004. The study aims to increase the chances of future success of forest rehabilitation efforts by identifying the strategies that best contribute to long-term sustainability with minimal negative effects on stakeholders. Specifically, the study derives strategic lessons from the past and ongoing initiatives. The study identifies and disseminate the most promising approaches and incentives for rehabilitation in different ecological and socio-economic situations.

Land degradation due to soil erosion is a major issue in the Ethiopian Highlands. Deforestation leads to ongoing gully erosion during the rainy season (June to September) and thus the hydrology of a watershed changes as dense gully networks cause direct drainage of rain water. To better understand watershed scale gully processes in the Ethiopian Highlands, three gauging stations were installed in the 56 km2 large Gumara-Maksegnit catchment in the northern Amhara region, to monitor discharge and sediment load in the gullies during rainy season.

This issue of Water Policy Briefing is based on research presented in When ?Conservation? Leads to Land Degradation: Lessons from Ban Lak Sip, Laos (IWMI Research Report 91) by Guillaume Lestrelin, Mark Giordano and Bounmy Keohavong. The research was carried out by the Managing Soil Erosion Consortium (MSEC)?a multi-country collaborative effort to better understand land degradation, and potential solutions, in upland areas of Southeast Asia. MSEC is coordinated by IWMI with substantial contributions from France?s Institute of Research for Development (IRD).

The atlas provides a pictorial overview of the application of land degradation surveillance a science-based approach to land health monitoring and assessment. Systematic sampling and observation of ground conditions are combined with new technology for rapid soil characterization and with fine to moderate resolution satellite imagery to provide powerful inference about soil, vegetation and socioeconomic conditions at local to regional scales.

Extensive land degradation in the Ethiopian Highlands jeopardizes rural livelihood. Intensified by increasing population pressure, farmers are forced to expand their arable land by deforestation and thus worsening the soil erosion problem. Through the application of various soil conservation measures, farmers and authorities try to prevent against further land degradation.

Soil organic carbon and nutrient contents are not influenced by exclosures established in communal grazing land in Nile Basin, northern Ethiopia

Land degradation through extensification of agriculture and overgrazing is an increasing problem across large expanses of the Ethiopian highlands that give rise to a loss in a range of ecosystem services. Ecological restoration through exclosure establishment has become increasingly important approach to reversing degraded ecosystems in Ethiopia and particularly in the Amhara regional state, northern Ethiopia.
