Aid Flows to the Water Sector: Summary

Core Content

This report, prepared for the High Level Panel on Water, provides an analysis of aid flows to the water sector, focusing on the role of grant funding and concessional financing in achieving the Sustainable Development Goal 6 (SDG 6) on water. It outlines the trends, distribution, and challenges in international aid and offers recommendations to improve the aid architecture and mobilize more effective financing for water-related development.

Main Findings

1. Overview of Aid Flows

• Official Development Finance (ODF) includes both Official Development Assistance (ODA) and Other Official Flows (OOF).
• ODA is grant-based or concessional, with a minimum grant element of 25% (calculated at a 10% discount rate).
• OOF includes nonconcessional loans and other forms of financing that do not meet ODA criteria.
• ODF to the water sector nearly tripled from $6 billion in 2003 to $18 billion in 2014, driven by the Millennium Development Goals (MDGs) and the International Water Decade (2005–2015).
• ODA to the water sector increased from $6.8 billion in 1995 to $12.9 billion in 2014, but grew at a slower rate than overall ODA, which rose from $42 billion to $140 billion over the same period.

2. Types of Aid Flows

• Concessional loans make up the bulk of ODF flows.
• Grants account for 28% of ODF (2010–2014), while nonconcessional loans make up 42%.
• Philanthropic funding for water remains modest, with grants representing less than 2% of total ODA to the water sector.

3. Allocation of Aid to the Water Sector

• Water supply and sanitation (WSS) receives the largest share of aid, accounting for ~57% of ODA and ~52% of nonconcessional financing from multilateral development banks (MDBs).
• Irrigation and hydropower make up the remainder of ODF and ODA flows.
• Grants are more prevalent in WSS (31%) compared to loans (69%).
• Irrigation is mostly funded through loans (82% of financing is in the form of loans).

4. Geographic Distribution

• Sub-Saharan Africa and South and Central Asia received over half of ODA for water, with 29% and 25% respectively.
• Public sector agencies account for ~70% of ODA to the water sector, while public-private partnerships represent only 1%.
• 91% of aid flows are directed toward specific projects, with 5% for core contributions and pooled programs, 3% for budget support, and 1% for technical assistance.

5. Funding Sources

• Bilateral donors account for ~70% of ODA to the water sector, with the top contributors being Japan, Germany, and the United States.
• Multilateral development banks (MDBs) now account for ~50% of ODF, up from 2003.
• World Bank Group (via IDA and IBRD) is the largest multilateral funder, with $920 million in annual ODA and $1.86 billion in annual nonconcessional loans.
• Inter-American Development Bank (IADB) and Asian Development Bank (ADB) are major contributors to nonconcessional financing.

6. Climate Finance

• Climate finance has increased significantly, but the water sector has captured only a modest share.
• From 2011 to 2014, seven major MDBs committed $23–$28 billion annually to climate finance.
• Water and wastewater management received 27% of adaptation finance, or $1.32 billion in 2015.

Key Challenges

• Aid flows to water have not kept pace with overall concessional financing.
• Fragmentation of aid flows is high due to the involvement of many agencies.
• Lack of coordination between agencies in allocating funds to different subsectors of water.
• Limited climate finance directed to the water sector.
• Few bankable projects exist, especially in the water sector.
• Ineffective use of development finance to catalyze private sector investment.
• Weak conditionality and results focus in aid programs.
• Limited knowledge and tracking of aid trends and modalities.

Recommendations

• Increase aid volumes to the water sector to meet SDG 6 targets.
• Align aid strategies with the SDG framework, improving coordination and targeting.
• Enhance climate finance mobilization, focusing on resilience and mitigation.
• Reduce fragmentation by creating platforms for collaboration and aligning objectives.
• Improve project preparation and provide more upstream policy support.
• Use guarantees and blending structures to leverage private financing.
• Increase focus on results and strengthen monitoring and reporting.
• Improve tracking mechanisms and establish regular "aid reviews" to better understand trends and modalities.

Data and Methodology

• The report uses data from the OECD/DAC and WASHfunders.org databases.
• CRS (Common Reporting Standard) is the main data source for ODF and ODA flows.
• The analysis covers a 20-year period (1995–2014), with some short-term assessments.
• The water sector is defined broadly to include WASH, WRM, irrigation, hydropower, and policy, administration, and management activities.

Conclusion

This report highlights the critical role of aid flows in supporting the water sector, particularly in achieving SDG 6. It emphasizes the need for increased funding, better alignment with SDG goals, and more effective use of development finance to catalyze private investment and improve outcomes. The recommendations aim to strengthen the aid architecture and ensure that the water sector receives the support it needs to meet global development objectives.
