The most pressing problem facing the Songkhla Lake Basin is land degradation and water pollution caused by land use changes and shrimp farming expansion. Action was taken to combat these issues and an Integrated Environmental Management approach was applied. The key lesson of this case is that replacing blueprint master planning approaches with process oriented planning frameworks increased sustainability significantly.
The Yangtze River Basin has been severely affected by climate change. To address this, the Yangtze River Basin Climate Change Vulnerability and Adaptation Report has been drafted to evaluate the impact on representative ecosystems and water resources, and pinpoint adaptation strategies. The experience has demonstrated that good adaptation measures should consider not only climate itself, but also other factors, such as economy, technology, as well as social and cultural norms.
Climate change and the increasing number of competing water users have led to the overexploitation of the Pangani river basin resources. Action has been taken to establishing environmental, economic and social implications of different river flow scenarios under expected climatic conditions. This helped to prioritize the allocation of water resources to meet basic human needs and those of ecosystems. The main lesson learnt was that providing a platform for dialogue between key stakeholders and increasing knowledge about the climatic variability and future risk are essential for successful water management solutions.
Toward water security and climate resilience
Mining is an important industry in West Africa. It contributes to economic and social development, but it also disrupts the natural and human balance, raising questions about the risk it poses to communities living near mining sites.
After the USSR was dissolved, Romania has experienced water scarcity for agriculture. The World Bank and USAID are providing loans/funds for irrigation projects and to strengthen water users associations. This case thus illustrates that irrigation subsidies may be needed to support agriculture until farming efficiency improves and returns from the sale of agricultural products can cover costs.
The 2nd High-Level Regional Policy Workshop focusing on “Adapting to Climate Change Induced Water Stress in Nile River Basin,” kicked off in Rwanda’s capital, Kigali, Thursday, 4th April 2013.
Le continent africain possède le plus grand nombre de bassins fluviaux transfrontaliers qui, collectivement, couvrent 64% de la superficie de l’Afrique et contiennent un peu plus de 93% de ses ressources en eau de surface. Même si une ressource en eau partagée est source potentielle de conflits, elle représente également un immense potentiel en termes de croissance économique du continent africain où, par exemple, moins de 4% de l’eau disponible est utilisée et moins de 7% du potentiel hydroélectrique est développé.
