8. MUS Development Domestic & Irrigation –Surplus water for irrigation 28 community systems 1,000 households Cost –$100 (tap) –$10-$35 (irrigation equip) Benefit –Income >$200/yr –Health & nutrition MUS with dual tap for drip irrigation and domestic use.

9. How it Works … The Value Chain Input Supplier Producer Output Markets

10. Supply-chain development: A key supporting investment for MUS Appropriate inputs for agriculture, drinking water (and sanitation) Embedded services Results: 240 agrovets 5 tap/micro irrigation manufactures 2 drip assemblers 133 micro-irrigation dealers 7 extension services (7 districts) Sales of 26,230 micro-irrigation systems Note: Only 1,280 purchased via micro-credit

11. Producer Build capacity of early adopters Facilitating access to inputs and credit Education Results: 31,000 households (200,000 people) in 1500 farmer groups $7.3 million in increased incomes (BCA 3:1) Year 1: $100/hh for 16,000 households Year 2: $195/hh for 26,000 households

12. Market development: Critical for economic opportunities linked to MUS Results: 43 market collection centers Established value chains across 9 districts serving 3 million

13. Government: key role Strategic investments Focus on market failures

14. Conclusions Economic valuation of alternative uses can serve as a decision making tool Opportunity cost of non-integrated management can be high Linking value chain approach to MUS can increase economic returns and reduce subsidies
