Summary of "Funding a Water-Secure Future: An Assessment of Global Public Spending"

Core Content

This report, Funding a Water-Secure Future: An Assessment of Global Public Spending, evaluates global public spending on water-related infrastructure and services, highlighting the need for increased investment to achieve water security and sustainable development goals (SDGs). It is part of the World Bank Group's Water Global Practice, supported by the Global Water Security & Sanitation Partnership (GWSP) and various international donors.

The report is structured into four main parts, each addressing different aspects of water sector funding, from the role of government to the efficiency of spending and recommendations for improvement.

Main Findings

• Government's Role in Water Sector: Governments play a critical role in leading investments in the water sector due to its unique characteristics such as merit goods, positive externalities, monopoly in service provision, and common-pool risks in production.
• Global Public Spending on Water: Public spending on the water sector is significant but insufficient to meet the SDG targets. The report provides four estimates of global infrastructure spending, ranging from $588.8 billion to $2.2 trillion annually.
• Water Sector Spending Gaps: There are substantial gaps in public spending to achieve universal access to safely managed water, sanitation, and hygiene (WASH) services and to meet SDG targets for water supply and sanitation (6.1 and 6.2). These gaps are particularly pronounced in low-income and middle-income countries (LICs and MICs).
• Efficiency and Productivity: The report assesses the efficiency and productivity of water sector spending using metrics like the Malmquist Productivity Index (MPI) and stochastic frontier analysis. It finds that inefficiencies in the water sector are widespread and have significant financial implications.
• Budget Execution Challenges: Budget execution rates in the water sector are generally low and vary by region, income level, and governance. Poor execution is linked to weak governance, regulation, and institutional capacity.
• Role of Subsidies: Subsidies in the water sector are unevenly distributed, often failing to reach the most vulnerable populations. Benefit incidence analysis reveals inequities in access to piped water and highlights the need for more targeted approaches.
• Public-Private Partnerships (PPPs): While PPPs are seen as a potential solution for funding and efficiency, their performance remains mixed and underutilized, with challenges in implementation and risk management.

Key Recommendations

1. Enhance Public Investment Management: Improve the efficiency and utilization of public spending through better management practices, including cost recovery and demand management.
2. Strengthen Governance and Regulation: Develop robust regulatory systems to facilitate long-term financing and risk pooling, ensuring sustainable and equitable investment.
3. Increase Domestic and International Funding: Encourage greater domestic investment and support from international donors to bridge the funding gap.
4. Promote Transparency and Data Access: Improve data transparency and communication to support informed decision-making and accountability.
5. Support State Capacity and Human Resources: Invest in building the capacity of governments to manage water sector investments effectively.
6. Address Inequities in Service Access: Ensure that subsidies and investments target the most vulnerable populations to improve access and reduce disparities.

Key Information

• The report includes detailed data and analysis from multiple sources, including the World Bank's own databases and external datasets.
• It presents a range of estimates for global public spending on water infrastructure and services, with variations based on different methodologies.
• The analysis covers both capital and recurrent expenditures, and explores the relationship between these expenditures and human development outcomes.
• The report also discusses the impact of climate change on water sector spending and the need for adaptive investment strategies.

Structure of the Report

Part 1: Statecraft – The Role of Government in Water

• Discusses the historical role of governments in water management.
• Highlights the importance of infrastructure investment in the water sector.
• Emphasizes the need for an integrated approach to water sector planning.

Part 2: Money Matters – What Is Spent and What Is Needed

• Examines the challenge of estimating public spending in the water sector.
• Provides detailed estimates of spending requirements and current spending levels.
• Analyzes the spending gaps to achieve SDG 6.1 and 6.2, and SDG 2 for irrigation.

Part 3: Liquid Ledger – Dissecting the Anatomy of Water Spending

• Focuses on the sources of funding, including ODA, public entities, and private sector contributions.
• Analyzes budget execution rates and their determinants.
• Assesses the efficiency of water utilities and the impact of inefficiencies on public spending.
• Investigates the distribution of subsidies and their effectiveness in improving access.

Part 4: Progress Not Perfection – Recommendations for Enhancing the Flow of Funds into Water

• Offers actionable recommendations to improve funding and investment in the water sector.
• Suggests reforms in public financial management, regulation, and governance.
• Emphasizes the importance of long-term financing and sustainable development.

Conclusion

The report underscores the critical need for increased and more efficient public spending in the water sector to achieve global water security goals and support sustainable development. It calls for a multi-faceted approach that includes better governance, improved budget execution, and targeted investment strategies to address both the quantity and quality of public spending.
