Niger
First 4 BFPs nearing completion
Niger
6 remaining BFPs started in 2008
Broad review of basins
• Development context
– Overall situation
• Water availability / use
• Water productivity
• Intervention and impact analysis
– Intervention: what ‘they can do’
– Impact: what ‘you’ can do
• Knowledge management
– Not much to show at this stage

• Irrigated crops
• Rainfed
• Livestock
• Fisheries

– Aquaculture

poverty
Measurable livelihood impacts

Seasonal water shortage, poor soils, low rice productivity

Impact pathway and
Knowledge management
• All impact pathways done
– All honest efforts
• Pathway depends on basin scale,
organization, existing network makers,
etc..
• Getting better engagement with CPWF
– Some more work needed with Topics
