Summary of "An Impact Evaluation of India’s Second and Third Andhra Pradesh Irrigation Projects"

Core Content

This report presents an impact evaluation of the Second and Third Andhra Pradesh Irrigation Projects (AP II and AP III), focusing on their role in poverty reduction and economic returns. It highlights the dual nature of these projects: while they have had significant poverty-reducing impacts, their economic returns have been disappointingly low.

Main Points

• Poverty Reduction Impact: The projects have contributed to substantial poverty reduction, particularly in the first year of irrigation. The poverty headcount in villages that received irrigation dropped by about 25%. The poorest households also saw some benefits, though indirect ones, such as increased seasonal employment, which helped reduce poverty.

• Income Distribution: The direct benefits from higher farm income were concentrated among the top quarter of beneficiaries, while indirect benefits, like employment, were more evenly distributed. However, the poorest still received fewer benefits.

• Economic Returns: The economic rate of return (ERR) for the projects was significantly lower than initially estimated. The ERR for the Srisailam Right Branch Canal (SRBC) was found to be close to zero, while the rehabilitation component had a return of less than 10%. These returns were well below the appraisal estimates of 24% and 24% for AP II and AP III respectively.

• Construction Delays and Cost Overruns: Both projects faced severe delays and cost overruns, which severely impacted their economic viability. The SRBC project, in particular, saw its first water delivery nearly 20 years after construction began.

• Cropping Patterns: The projects led to increased crop yields and cropping intensity, but the expected diversification into high-value crops did not materialize. Irrigated farms remained focused on water-intensive crops like paddy, which limited the economic benefits.

• Participatory Irrigation Management (PIM): Andhra Pradesh has been a leader in PIM, with over 10,000 water user associations (WUAs) established. However, WUAs are not fully capable of managing the operations and maintenance (O&M) of irrigation systems due to lack of technical and financial capacity. They also struggle with water allocation issues, especially between communities.

• Government Role: The government remains essential in managing irrigation systems, particularly in addressing technical and financial challenges. The lack of effective water pricing and the inability of WUAs to manage water distribution effectively underscore the need for continued government involvement.

• Policy Implications: The evaluation supports the World Bank's shift towards institutional reforms and community involvement in irrigation management. However, it also highlights the need for more rationalized project selection, planning, and design to avoid cost overruns and delays.

Key Information

• Project Overview:

  • AP II and AP III aimed to irrigate 393,000 hectares of land.
  • SRBC was a new command area, while the Sriramasagar Project (SRSP) was a rehabilitated one.
  • These projects were expected to benefit over 300,000 farm households.

• Methodology:

  • The study used a quasi-experimental design with survey data and reanalysis of existing data.
  • It included both quantitative and qualitative data collection.

• Challenges:

  • Cost overruns and delays.
  • Poor water pricing structures leading to excessive water use.
  • Limited effectiveness of WUAs in managing O&M and water allocation.

• Lessons Learned:

  • Large-scale irrigation projects can have significant poverty-reducing impacts.
  • Efficient implementation is crucial for the economic viability of such projects.
  • WUAs are important but require support and guidance from the government.
  • There is a need for more realistic appraisals and better planning to ensure project success.

Structure

• Introduction: Sets the context of the study and its relevance to poverty reduction and irrigation policy.
• The Irrigation Paradox: Discusses the tension between poverty reduction and low economic returns.
• The Andhra Pradesh Context: Provides background on the state and the irrigation projects.
• Evaluation Questions and Approach: Outlines the key questions and the methodology used.
• Project Implementation: Details the implementation of AP II and AP III.
• Water User Associations (WUAs): Explores the role, structure, and effectiveness of WUAs.
• Economic Benefits: Analyzes the direct and indirect economic impacts of the projects.
• Social Impacts: Discusses the social effects, including the role of WUAs and the distribution of benefits.
• Summary and Lessons Learned: Concludes with the main findings and policy implications.

Conclusion

The evaluation shows that while the Second and Third Andhra Pradesh Irrigation Projects have had a positive impact on poverty reduction, their economic returns have been low due to delays, cost overruns, and inefficiencies in water management. The role of WUAs in promoting community involvement is significant, but their capacity to manage O&M and ensure equitable water distribution is limited. The findings support the need for improved project planning, realistic appraisals, and continued government involvement in irrigation management.
