Livestock interventions for building climate change resilience in the drylands

Pierre Gerber, Anne Mottet, Giulia Conchedda TCI Investment Days 16-17 December 2014

The economics of resilience in the African Drylands

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

Livestock background report to the Flagship report on the economics of resilience

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?

FEED AVAILABILITY Biogenerator Total and accessible biomass GLEAM Crop production & crop residues (GAEZ) BAU: 1999-2011 Scenarios: ≠ sequence 2000 adjusted to Conforti projections for 2012-2030 ANIMAL REQUIREMENTS Gridded Livestock of the World MMAGE Requirement/ animal categoryv Conforti projections & scenarios (interventions & droughts)

FUTURE 2012-2030

GLEAM Feed & system modules -

GLEAM fills up the requirements: First by-products (if system and cohort allow) Then crops residues Then leaves from non agricultural biomass up to a maximum % Then other natural vegetation (grass) At pixel level, zero mobility

- Feed “balances” and maps - TLU not meeting requirements

At grazing shed level, full mobility

- Feed balances - Feed rations & digestibility - GHG emissions IMPACT Meat & Milk Supply, demand & prices ECORUM Financial and economic rates of return

Define a new functional geographical unit

Drylands defined based on the Aridity Index, which is consistent with UNCCD practice Particular emphasis is given to the vulnerable areas in West and East Africa 10

Relative merits of policies to reduce feed deficit

Conclusion

• • • • • • 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?
