Summary of the Methodology for Ranking Irrigation Infrastructure Investment Projects in the Republic of Uzbekistan

Core Content

This document outlines the methodology for ranking irrigation infrastructure investment projects in the Republic of Uzbekistan, developed by the World Bank in collaboration with the Government of Uzbekistan (GOU) and local stakeholders. The purpose is to provide a systematic and transparent approach to selecting projects for rehabilitation and modernization of the irrigation and drainage systems, which are critical for agricultural productivity and rural development.

The report is part of a broader effort to address the urgent need for infrastructure repair and to prioritize projects among the 180 proposals available. It emphasizes the importance of a national strategy for the water sector, including a 15-20 year perspective plan and a 5-10 year medium-term investment plan. The methodology aims to ensure that investment decisions are based on a comprehensive analysis of economic, social, environmental, technical, financial, and legal factors.

Main Points

1. Background and Context

• The irrigation and drainage infrastructure built under the Former Soviet Union (FSU) serves 4.3 million hectares of agricultural land and many villages.
• The infrastructure is in urgent need of repair and rehabilitation due to years of underfunding and inefficiencies in water resource management.
• The country loses approximately US$1.7 billion annually due to poor water management, and agricultural production is decreasing by about US$2.0 billion per year.

2. Data Collection and Challenges

• Initial data collection was slow and inconsistent as many project proposals were not well-defined.
• The TWG (Technical Working Group) used the Investment Project Data Sheets (IPDS) to standardize and collect relevant information from Sub-Basin Authorities (BAISs).
• Only 26 projects were fully analyzed and ranked, while the remaining 154 were not deemed suitable for evaluation due to insufficient data.

3. Ranking Methodology

• The ranking process is based on Multi-Criteria Decision Analysis (MCDA), which includes the following criteria:

  • Economic Performance
  • Social Impact
  • Environmental Impact
  • Technical Considerations
  • Financial Considerations
  • Legal Considerations

• The Weighted-Average Model is used, which allows for the integration of multiple criteria into a single ranking score.

• Projects with pumping heights exceeding 15 meters typically do not yield a positive economic return and may be ranked lower unless they score highly in social or environmental impact.

4. Key Findings and Recommendations

• A National Rural Development Strategy is recommended to ensure coherence in investment decisions and to address strategic issues holistically.
• The preparation of such a strategy is estimated to take 5 years and require significant financial resources.
• The GOU is advised to seek grant assistance from the international community to support the development of this strategy.
• Until a national strategy is in place, the ranking methodology should be used to guide annual investment budgets for the irrigation and drainage sector.
• Donor coordination should be strengthened to avoid overlaps and contradictions in policy dialogue with the GOU.

Key Information

• Currency Equivalent: 1 Soum = $0.00095, 1 USD = 1,304 Soums (End 2007)

• Project Count: 26 projects were considered for ranking.

• Annexes:

  • Annex 1: Ranking Matrix
  • Annex 2: Projects' Location Map
  • Annex 3: Projects Considered for Ranking
  • Annex 4: Basin Authorities for Irrigation System - Investment Project Proposals
  • Annex 5: Investment Project Data Sheets ("Project Passport")

• Methodology Sources: The ranking methodology is adapted from international literature and includes a Project Cycle framework.

Strategic Issues Identified

• Water Resources Assessment: Requires regional cooperation and a clear, flexible water allocation plan that considers long-term sustainability.
• Sustainability: Emphasis on preserving natural flows and ecosystems through research, flow meters, and awareness campaigns.
• Institutional Reforms: Need for a clear division of roles between policy formulation, regulation, and service delivery to reduce political interference.
• Land Property Rights: Current land tenure systems may not incentivize investment in land improvement, and the use of land as collateral for credit should be revisited.
• Data Reliability: Much of the data used in the study comes from outdated records, and updated data collection is essential for accurate decision-making.
• Pump Station Rehabilitation: About 5,100 pump stations exist, with many operating above the 15-meter economic threshold. The GOU must decide whether to continue subsidizing these or phase them out based on demographic and economic grounds.

Conclusion

The methodology provides a structured and transparent way to prioritize irrigation projects, ensuring that investments are made in a manner that maximizes economic and social returns while considering environmental and legal factors. It highlights the need for a long-term, integrated national strategy for the water sector, which should be supported by international assistance and donor coordination. The report serves as a guide for future project selection and management in Uzbekistan's irrigation infrastructure development.
