More milk, meat and fish by and for the poor

Livestock and Fish CGIAR Research Program(CRP 3.7)

Mark van Wijk

3.7 Livestock and Fish: Aim

To increase the productivity of small-scale livestock and fish systems in sustainable ways, making meat, milk and fish more available and affordable to poor consumers across the developing world

Themes

• Technology Development: Improved technologies to sustainably increase productivity and efficiency of livestock and fish production (health, genetics, feeding)

• Value Chain Development: Development strategies for pro poor, gender equitable ‐ ‐value chains for livestock and fish products

• Targeting, gender and impact assessment

Targeting

• LCA’s• Ex-ante impact assessment across scales

(livestock subsystem, farm, livelihood, community, landscape)

• Tradeoffs between productivity and environment

Targeting: trade off across scales/levels

Community

Farm livelihood

Environment

Targeting: trade off across scales/levels

Community

Farm livelihood

Environment

Farm models: simulation and optimization

Multi-agent models,land use models

rangeland, hydrology, soil C and GHG models

Approaches envisaged: heavy computing

ALLEVIATION!

Toys are in place, but…

• (rapid) parameterization / model testing across sites

• Upscaling/outscaling• Models good for strategic analyses, but how

meaningful on the ground
