They regulate climate, air quality and water flow, and contribute to protection against natural hazards and the impacts of extreme events. The Convention was designed to address global concerns regarding wetland loss and degradation.Sustainable Use of Biodiversity in Dryland Biosphere Reserves in West Africa Regional Project on building scientific and technical capacity for effective management and sustainable use of biodiversity in dryland biosphere reserves in West Africa.Island and coastal areas biosphere reserves around the world have different natural, cultural, socio-economic and political characteristics. Drylands also contribute a number of high-value products of global economic importance, at least 30% of the world’s cultivated plants and many livestock breeds originate in drylands.
On the east slopes of the Wienerwald there is a geological rupture zone, with hot springs and impressive marine terraces of a former sea. UNESCO-MAB assesses the impacts of global and climate change on fragile mountain ecosystems, using mountain biosphere reserves as sites for study and monitoring. km.

They, therefore constitute an important genetic reservoir that is becoming increasingly valuable for climate change adaptation.The World Network of Biosphere Reserves extended to West Africa in 1977 by the creation of the park Taï in Côte d'Ivoire. This Convention is the sole legally binding international agreement linking environment and development to sustainable land management.UNESCO-MAB assesses the impacts of global and climate change on fragile mountain ecosystems, using mountain biosphere reserves as sites for study and monitoring.Focal point at the MAB Secretariat: Maria Rosa CárdenasWetlands are ecosystems saturated with water, either seasonally or permanently. This already takes into account some biosphere reserves that have been withdrawn or revised through the years, as the program's focus has shifted from simple protection of nature to areas displaying close interaction between man and environment.
