Desertification poses a substantial threat to livelihoods and regional stability. An estimated 50-200 km southward shift of the boundary between semi-desert and desert has occurred since rainfall and vegetation records were first held in the 1930s. The remaining semi-desert and low rainfall savannah on sand, which represent some 25% of Sudan’s agricultural land, are at considerable risk of further desertification.
Possible impacts on agriculture include a 70% drop in yields of sorghum (maize). This is against the backdrop of a long-term decline in rainfall that, coupled with overgrazing, has seen deserts encroach in some regions of Sudan by 100 kilometres over the past 40 years. Agricultural production comprises 26% of Sudan’s annual GDP, a figure which has plummeted from 42% in 2000 (World Bank, 2008). The interaction of climate change with ongoing environmental degradation has the potential to exacerbate a wide range of conflicts, undermining efforts to build a basis for long-term peace and human security.
