Development History

ES and policy Ecosystem Services increasingly underpinning international policy development. Watershed-scale ecosystems as the focus of political and economic activity. Framework for spatial targetting and landscape planning MEA vision: Local institutions are strengthened and local ecosystem management strategies are common; societies develop a strongly proactive approach to the management of ecosystems

Rainfed problem sets 1.Recapitalising African soils and reducing land degradation (water, nutrients, biota and C) 2.Revitalising productivity on responsive soils (information, value chains and incentives based) 3.Increasing agricultural production whilst enhancing biodiversity- intensification and trade-offs 4.Enhancing availability and access to water and land for pastoralists (trade-offs) 5.Reducing risk by provision of supplemental irrigation (resilience) CRP links 1.1, 1.2, 2, 7

Rainfed- Basins SRP’s: Synergies and Gaps Synergies Ecosystem approach based on stocks and flows Common platforms Continuum to irrigated agro-ecosystems Gaps Other basin land uses: Trees, urbanisation Basin scenarios for future development trajectories Critical thresholds/ tipping point metrics?

Possible Scenarios What ES can a basin produce? What does society want it to produce? How will this vary, with different drivers: – Population –Climate Change
