Climate changes and food security impacts and vulnerability of rural and urban populations

The picture is bleak for food security in West Africa, due to the expected impacts of climate changes. Indeed, increased intensity of extreme weather events, droughts and water stress, warming of water and decreasing fish production, land degradation, changes in the distribution of animal and human vector-borne diseases, etc. are anticipated (IPCC, 2013). These effects are aggravated by a significant degradation of land and natural resources by human activities. Despite a possible increase in precipitation in some areas, West Africa is in a delicate situation because of its environmental, economic, and political vulnerabilities. Among others, key vulnerabilities are dependence on agriculture, low incomes, and the already significant variability in climate. Crops in West Africa are already affected by drought and depletion of water resources. Pests and diseases are common, and livestock is affected by regular outbreaks. Pastures rarely produce enough forage. People are dependent on markets and thus undergo changes in local and global food prices. The diet of the population is generally poor in animal proteins, sometimes in vegetables. According farming systems, specificities emerge in terms of vulnerability, such as: • Risks of significant flooding in irrigated farming system; • Low adaptation investments in farming systems based on tubers and cereals; • Isolation, high land degradation, and silting up of ponds in agro-pastoral farming systems based on millet and sorghum; • Drying up of water sources, bush fires, conflicts, and adverse terms of trade for cattle ranchers in pastoral farming system; • Shortages of drinking water in urban and peri-urban areas. Successful adaptation practices do exist. Some of them are presented in another note
