  1. Valuing the Multiple Uses of Irrigation Water Ruth Meinzen-DickInternational Food Policy Research InstituteWashington D.C., USA

  2. Multiple productive uses of water • Agriculture • Field crops • Gardens • Permanent vegetation • Livestock (including waterfowl) • Fisheries in reservoir, canals, fields • Aquatic plants: lotus, reeds, etc. • Non-agricultural enterprises • Brick making, dyeing, retting, etc. • Tourism, ecotourism

  3. Other essential uses of water • Domestic water supply • Drinking water • Bathing, washing • Environmental uses • Wildlife • Groundwater recharge • Recreation • Religion

  4. Stakeholder Analysis • Identify multiple users of water, interest groups • By occupational • By gender • By generation within the household • Inside and outside the irrigation system • Look for marginalized groups • Government agencies dealing with each use

  5. Management issues • Improving “efficiency” may cut off some uses, reduce overall value of output • Attention to water quality effects, interactions between uses • Infrastructure requirements (e.g. lining for livestock access)

  6. Institutional issues • Can government agencies or “user groups” accommodate all needs? • Recognizing formal and informal rights • rights defined by time, space, quantity, quality • Especially important with water transfers

  7. Multiple Water Uses in Kirindi Oya, Sri Lanka

  8. Economic issues • Capturing value of all uses • in project evaluations • in financing projects • in all prospective water transfers

  9. Production and revenue, Tamil Nadu irrigation tanks

  10. Conclusions • Irrigation water produces more than just grain • Identify all uses, users • Information on value of all uses leads to better policies • Providing access to “marginal” users, for livelihood security • Implications for water rights, especially in transfers • Opportunities, but also trade-offs in optimizing joint product of all uses, users
