Scientists and government officials are collaborating with communities to test out new approaches to reversing land degradation—methods that might have potential to change the status of the entire highlands region from vastly degraded to successfully restored.
If we utilize our water better upstream, what will happen downstream? Will water availability decrease? Is watershed improvement a zero-sum game with the gains upstream deducted from the situation downstream, or is it an overall system improvement? Or if we take a broader view of water-related ecosystems services, how does more intense upstream water use have an impact on all relevant ecosystem services in the entire area? Who are the winners and who are the losers? Frank van Steenbergen, Tesfa-alem Gebreegziabher Embaye and Eyasu Hagos take a crack at answering these questions.
A a new tool, still under development, will 'triangulate' available plant traits linked to ecosystem processes to guide restoration efforts while facilitating to practitioners’ and other relevant stakeholders' selection of locally adapted species for restoring ecosystem services.
Water wars have been announced by media and policy analysts over the last twenty years and the Nile has always been one of the rivers spotted as “up for grab”. However, in spite of these prophecies what we have been mostly witnessing is a process of difficult, uneven, slow, sometimes contradictory but still peaceful negotiation among the riparian countries.
Users of wetlands in the Nile River basin are increasingly confronted with tough trade-offs, as wetland areas become overexploited, deteriorate and ultimately fail to provide the benefits that communities and ecosystems depend on.
In the Gash Spate Irrigation Scheme of Sudan, farmers are able to cultivate watermelon as a second crop in the end of October – long after the rains have fallen and the floods have been diverted. So where does the water come from?
The Nile Water Lab is a new web platform that presents a wide range of views on irrigation projects along the Nile, both views from people on the ground and views that are usually hidden away in policy reports and journal articles.
The number of Africans at risk of malaria who live near dams will nearly double to 25 million by 2080 as areas where the disease is not currently present will become transmission zones due to climate change, researchers said on Monday.
