1. Livestock interventions for building climate change resilience in the drylands TCI Investment Days 16-17 December 2014 Pierre Gerber, Anne Mottet, Giulia Conchedda

2. Coordinator: World Bank 1.Characterize current and future challenges to reducing vulnerability and increasing resilience in drylands 2.Identify main interventions to enhance resilience, estimate their costs, and assess their effectiveness 3.Provide an evidence-based framework to improve decision making on alternative options to enhance resilience 4.Promote sharing of regional and global knowledge on resilient development in drylands Complementarity with governments and partners’ current engagements especially in in the Sahel and the Horn of Africa The economics of resilience in the African Drylands

3. Coordinator: Cees de Haan, WB Action Contre la Faim, CIRAD, FAO, IFPRI and ILRI Modelling likely trends of livestock systems in the drylands of Sub- Saharan Africa a)What are the likely impact of climate change on feed availability and animal productivity? b)How to improve the resilience of livestock systems?  assess the potential of a set of technical interventions a)What are the opportunities for the drylands to contribute to projected increase in demand for animal products? Livestock background report to the Flagship report on the economics of resilience

14. At “grazing shed” level: enough resources to support livestock sector growth but local shortages  animal mobility or feed transportation Baseline 2012-2030: use 2.5 times more available (but not necessarily accessible) resources. In some scenarios, this may go up to 3.5 times. This calls for interventions in the areas of animal mobility (corridors, security, border regulations, health, tenure, ….) and feed management (storage, processing, transport, …) Animal health interventions need to be coupled with interventions that increase access to feed. Otherwise, full benefits may not be achieved and conflicts over resources may increase. Maps produced by this assessment can support targeting intervention for increased feed accessibility Livelihoods: how many people will the sector support in the future? Conclusion
