Watershed-Based Systems for Sustainable Agriculture and Resource Management: Case Studies Across Continents

This project involves a thorough review of watershed-based systems with a focus on sustainable agriculture and natural resource management. It includes 8 in-depth case studies covering various regions, analyzing success factors, and sharing information with investigators to submit proposals. The project aims to develop case studies, identify critical issues, and provide guidance for solving water resource problems in developing countries.

  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
