  1. Watershed-based Systems Saied Mostaghimi Biological Systems Engineering Virginia Tech

  2. Scope • Review literature on the state of the science in watershed-based systems • Hired a part-time research associate • Two graduate students • Identified relevant watershed protection and restoration projects • Sustainable agriculture and natural resource management • Cross-system linkages • Selected 15 major projects for detailed review • Shared information with several investigators who submitted bridge proposals and planning grants

  3. Scope • Identify Projects for case study analysis • Develop case studies characterizing critical SA & NRM system issues • Eight case studies were analyzed • Added articles to SANREM metadata bank • Water supplies quantity and quality • Factors that defined success or failure

  4. Case Studies Sub-Saharan Africa • Senegal River Basin integrated • management model • Small dam protection in • Zimbabwe

  5. Case Studies Europe and Eurasia • Operation Twinkling Star: • Pronya River Watershed, Russia • Mountain watersheds in the • Czech Republic

  6. Case Studies Asia and the Near East • Watershed management in • Karnataka, India • Erosion control in the Upper • Mahaweli in Sri Lanka

  7. Case Studies Latin America & the Caribbean • Water budget model for the • Cabuyal watershed in Columbia • Economic model for the Rio Chiquito • watershed in Costa Rica

  8. Scope • Draft synthetic review of the state of the art and science • A first draft completed • Chapter 4

  9. Purpose To provide guidance in solving water resources problems at the watershed scale in developing countries.

  11. USDA-NRCS Planning Process PHASE I Collection and Analysis PHASE II Decision Support PHASE III Application and Evaluation

  12. I. Collection and Analysis • Forming a stakeholder • committee • Agree on the nature of problems • Developing objectives • Measurable and obtainable • Basic data needs • Tools for collecting and • analyzing data

  13. II. Decision Support • Suggestions for developing • alternatives • Cost-effectiveness and implementation • Tools for evaluating alternatives • Stakeholders, rather than • program funding, should drive • the selection process.

  14. III. Application and Evaluation • Encourage farmers to provide feedback on the practices • Refine the objectives • Example criteria are listed • The problem with incentives • Benefits not evident for several years • Incentives used to prime implementation • Stakeholder evaluation of practices

  15. Additional Study Needs • Handbook of field measurement • and estimation methods • Development and access of • basic GIS layers • Documentation of long-term • results

  16. Keys to Success • Stakeholder-driven process • Availability of basic data • Measurable and obtainable objectives • Practices with obvious short-term • benefits to the producer • Cautious use of incentive payments • Means for evaluating and improving • strategies
