Dryland peoples face uncertain futures, including drought, climate change, ecosystem degradation, and market failures
Drylands are areas exposed to arid, semi-arid or dry-sub-humid climate and therefore threatened by desertification. These climatic conditions are defined easily by a simple coefficient reflecting the ratio of potential evaporation and precipitation (0.05 - 0.65). About 40% of Sub-Saharan Africa is covered by drylands, in which 206 million people or 36% of the total population lives. Poverty levels are extremely high-the average Human Development Index in Sub-Saharan African countries that have large dryland areas is as low as 0.35.
do you prefer Ecosystem approach to Drylands Environmental Management,
based on adaptive management?
Ecosystem approach recognizes the need to maintain provisioning services of ecosystems (such as food, fibre, fuel, freshwater) through maintenance of ecosystem supporting and regulating services (such as hydrological regulation, nutrient cycling, and biodiversity). Adaptive management of ecosystems aims to promote, within national development processes, more reliable and efficient learning from project experience through use of scientifically rigorous testing of policy and management interventions. A regional approach is needed to help ensure that solutions match the scale of the dryland environmental problems and that scarce resources are wisely targeted to where they are most needed. At a local level, there is need to build capacity of communities for adaptive management strategies based on income-generating agroforestry practices integrated with other soil conservation practices and local land use planning.
