Preventing contamination of natural waters and controlling the volume and improving the quality of drain and wastewater from the reclaimed territories of the Non-Chernozem Zone of Russia requires applying a set of measures as well as developing new technical solutions.
Cooperative management of transboundary river basins is widely recognized as important. Emphasis on joint management of shared aquifers has also grown in recent years. Perhaps surprisingly, despite abundant focus on transboundary surface water and growing focus on shared groundwater, there is scant focus on their intersection.
Soil and water conservation (SWC) practices like that of erosion control and soil fertility measures were commonly practiced in the semiarid region of southern Mali since the 1980s. The SWC practices were mainly meant to increase water availability in the subsurface, reduce farm water runoff and gully formation and improve nutrient content of the soil, thereby increasing crop yield.
Study region : Transboundary aquifers (TBAs) of Africa.
Study focus: Review of work on TBAs in Africa, including an overview of assessments and management efforts that have taken place over the last half century.
Land degradation is a major challenge limiting crop production in Ethiopia. Integrated soil and water conservation is widely applied as a means to reverse the trend and increase productivity. This study investigated the effects of such integrated approaches at two sites, Jeldu and Diga, in Western Ethiopia.
