This change in livestock productivity is induced by recurrent droughts, scarcity and distance from pastoral areas and water points. This situation is the result of global warming and abnormal biomass withdrawals that significantly affect the already very fragile level of food insecurity. The convergence of these different factors affects the way in which herds are managed, with in particular the development of peri-urban farming and the implementation of breed improvement programs. Impacts on habitat, urban planning and spatial planning concern the risks of intrusion of marine waters and flooding of coastal infrastructures and cities, including Nouakchott and Nouadhibou, respectively political and economic capitals.
