Sénégal

Senegal gives access to a particularly interesting diversity of ecological contexts of livestock and agriculture. Precipitation fluctuates between more than 1000 mm in the south and less than 300 mm in the north. Overall, rainfall has declined in Senegal by 35% over the last 50 years, an evolution that allows to address adaptation issues fully to the many changes under way.

The PPZS, through national and international projects that closely involve local development actors and with the support of ISRA regional research centers (Dahra, Kolda), builds and maintains experimental historical and pluri  disciplinary data in the main agro-ecological zones on mobile pastoral and agrosylvopastoral livestock systems that are a major component of the development of landscapes .

  •  Senegal River Valley (200-300 mm): Around the irrigated perimeters of Richard Toll, Dagana, Lac de Ghuiers: Dairy sectors and development of dairy farming in the Waalo and Diéri  interaction with current agroindustrial dynamics: rice, sugar cane, horticulture ...) The numerous projects Milky ways, AnimalChange Glofood are conducted in partnership with actors such as GRET, LDB, SAED, UGB, ...
  • Ferlo: in the silvopastoral reserve (300-400 mm rainfall), around water boreholes network that has structured the use of the landscape for some 40 years: the PPZS teams conduct ecological monitoring and deploy support to the governance of the Pastoral Units (dynamics of local knowledge and evolution of income in communities and settlements, carbon footprint and greenhouse gas emissions from the Widou PU ). These activities are supported by the SIPSA, Animal Change, PRAPS projects
  • Groundnut Basin, in close partnership with the IRD and Niakhar Long-Term Observatory, PPZS analyzes the interactions between livestock farming and traditional peanut cultivation, farm evolution trajectories and nutrient flows at the farm level Territory subject to strong demographic dynamics. Activities are supported by the CERAO, WAAP projects.
  • Casamance (> 1100 mm): In Kolda, at the Sara Yero Bana site, with the support of the ISRA Zootechnical Research Center, PPZS capitalizes about 20 years of follow-up on herd dynamics and Spatialization of the use of resources by animals during the year. The data allow to trace the evolution of nitrogen and carbon balances and animal contributions to the flows of these elements essential for the equilibrium and durability of cereals maize sorghum rice cultivation and of the food security of family farms. Projects such as the ABT program, or more recently WAAP-EFFEFAECES, contribute greatly to the maintenance of the experimental system.
