Integrated watershed management (IWM) is emerging as an alternative to the centrally planned and sectoral approaches that currently characterize the planning process for dam construction in Ethiopia. This report clarifies the concept of IWM, and reviews the major social, environmental and economic problems caused by dams in Ethiopia and elsewhere. Dams are planned from a top-down perspective in Ethiopia, some people are relocated against their will, haphazard landuse changes can occur, and soil erosion and reservoir sedimentation can increase. Many communities affected by dam constructions have not been sufficiently recognized or compensated, and environmental protection measures such as land-use planning and soil and water conservation have not been adopted in watersheds in which construction of dams is occurring. Furthermore, revenues generated from hydropower and water supplies often benefit urban dwellers, or the national economy, at the expense of rural inhabitants in watersheds. Creation of a multistakeholder platform, integration of soft system methodology with hard system tools, and completion of environmental protection measures should be among the major components of an improved planning methodology for construction of new dams in Ethiopia. This translates into an environment wherein science and knowledge can help watershed inhabitants create a diversity of locally appropriate resource management solutions. Effective implementation of environmental policies and strategies could improve the quality of watershed-based developments. The conclusion is that the IWM approach is a good alternative to effectively address the social, environmental and economic problems associated with planning and constructing new dams in Ethiopia.

Developing models to predict on-site soil erosion and off-site sediment transport at the agricultural watershed scale represent an ongoing challenge in research today. This study attempts to simulate the daily discharge and sediment loss using a distributed model that combines surface and sub-surface runoffs in a small hilly watershed (< 1km2). The semi-quantitative model, Predict and Localize Erosion and Runoff (PLER), integrates theManning–Strickler equation to simulate runoff and the Griffith University Erosion System Template equation to simulate soil detachment, sediment storage and soil loss based on a map resolution of 30m 30m and over a daily time interval. By using a basic input data set and only two calibration coefficients based, respectively, on water velocity and soil detachment, the PLER model is easily applicable to different agricultural scenarios. The results indicate appropriate model performance and a high correlation between measured and predicted data with both Nash–Sutcliffe efficiency (Ef) and correlation coefficient (r2) having values>0.9. With the simple input data needs, PLER model is a useful tool for daily runoff and soil erosion modeling in small hilly watersheds in humid tropical areas.

The Northern Uplands of Vietnam form one of the largest ecological regions in the country, characterized by complex biophysical conditions and a high diversity in ethnic minorities, cultures, and farming systems. The Doi moi (“renovation”) program has, since the early 1980s, resulted in significant changes in agriculture production and related economic trends. However, poverty, low agricultural productivity, and land degradation are still major problems. This article illustrates the factors that drive these problems by analyzing agricultural land use in Suoi Con, a small agroforestry watershed in the Northern Uplands. We first identified the current land-use systems and analyzed constraints on agricultural production. The results indicate that although low soil fertility and land degradation are considerable problems, availability of household capital, low technology levels, and land fragmentation are major constraints on agricultural development. These constraints were analyzed from different points of view to identify mismatches between the implementation of top-down government policies and specific conditions that may explain why actual land-use change in the Northern Uplands deviates from the government's development plans. Results of land-use analysis in the Suoi Con watershed suggest that participatory and bottom-up approaches are needed to better understand problems and opportunities in household agricultural production in order to develop appropriate land-use plans and policies.
