The Volta River Basin covers a region of about 400 000 km2 with a population of approximately 29 million. The Volta Basin runs through the semi-arid to sub-humid areas of six countries: Benin, Burkina Faso, Côte d’Ivoire, Ghana, Mali and Togo. The Basin is highly vulnerable to meteorological and hydrological events. Baseline socio-economic issues in the region are today exacerbated by considerable changes in the climate over recent decades – a reduction in precipitation and temperature increase.

The Earth’s atmosphere's main cleansing mechanism removes chemicals from the air and deposits them onto land and water surfaces. While the effects of these removal processes are mostly beneficial, some can have negative impacts on human health, ecosystems and food security. For example, acid rain – the acidification of rainwater due to nitrogen and sulfur emissions – damages forests, kills insects, corrodes industrial metal structures, etc. Such adverse impacts of deposition are of great interest to society as a whole and more particularly to policymakers, thus, WMO decided to undertake the...
