Resilience of Sahelian ecosystems

2009-05-14 - 2009-05-14

Seminar with Christian Valentin, Thursday 14 May, 1400-1500.

Seminar title: "Resilience of Sahelian ecosystems through the uneven spatial distribution of natural resources"

The Sahelian region that spans the entire continent from the Atlantic Ocean to the Red Sea is one of the major world hot-spots in term of population growth, poverty, food security, water demand, land degradation and climate risk.

The area and its peoples suffered several devastating droughts and famines in 1972-1973 and in 1983-1984 with dramatic consequences on water, soil and vegetation resources associated with massive losses in livestock.

Many studies have shown a remarkable resilience of the Sahelian ecosystems since. This presentation demonstrates this resilience and draws lessons for land and water management in the semi-arid regions taking the tiger bush as an example.
