Summary of Reducing Inequalities in Water Supply, Sanitation, and Hygiene in the Era of the Sustainable Development Goals

Core Content

This report, Reducing Inequalities in Water Supply, Sanitation, and Hygiene in the Era of the Sustainable Development Goals: Synthesis Report of the WASH Poverty Diagnostic Initiative, is a synthesis of country-level analyses from 18 low- and middle-income economies, including the West Bank and Gaza. It focuses on the inequalities in access to water, sanitation, and hygiene (WASH) services and how these impact human development and health outcomes. The report is led by the World Bank's Water and Sanitation Program and supported by the Swedish International Development Cooperation Agency.

The Sustainable Development Goals (SDGs) emphasize the need for universal access to safe and affordable WASH services by 2030, with a focus on improving service quality and ensuring long-term sustainability. This requires not only expanding access but also addressing the root causes of inequality in service delivery, such as political and institutional barriers, and the uneven distribution of resources.

Main Points and Key Findings

1. Inequalities in Access to WASH Services

• Inequalities exist between rural and urban areas, and among different income and wealth groups.
• In many countries, the poorest 40% have significantly less access to improved sanitation and water services compared to the wealthiest 60%.
• In Guatemala, only 33% of indigenous populations have access to improved sanitation, versus 70% of non-indigenous populations.
• In Niger, 90% of rural people defecate in the open, and 51% lack access to improved water.
• In Tunisia, the bottom 20% receive only 11% of water subsidies and 10% of sanitation subsidies, while the top 20% receive nearly 27% and 33%, respectively.

2. The Role of WASH in Human Development

• WASH services are critical to achieving SDG 2 (Zero Hunger) and SDG 3 (Good Health and Well-being).
• Poor WASH conditions are linked to malnutrition and diarrheal diseases, which have long-term negative impacts on children.
• In several countries, including Guatemala, Niger, the Democratic Republic of Congo, Mozambique, Yemen, and Bangladesh, over 40% of children under 5 are stunted, with WASH-related undernutrition contributing to this issue.
• Improved WASH services can reduce the risk of diarrheal disease and support better health outcomes.

3. Service Delivery Challenges

• In many countries, the provision of piped water is declining, even as demand increases.
• In Nigeria, piped water access in urban areas dropped from 29% in 1990 to less than 10% by 2015.
• In the Democratic Republic of Congo, it fell from 48% to 17% in the same period.
• Poor service delivery is often due to a lack of coordination, limited planning, and misaligned resource allocation.

4. The Need for Better Data and Diagnostics

• The report emphasizes the importance of using data to identify inequalities and inform targeted investments.
• It introduces the Human Opportunity Index, which highlights how time spent on WASH-related activities affects human development.
• The WASH Poverty Risk Model helps assess the impact of WASH on nutrition and health outcomes.

5. Policy and Institutional Constraints

• Policy commitments often do not match actual implementation.
• Institutional arrangements, political will, and local norms influence the effectiveness of WASH interventions.
• There is a need for a problem-driven approach to diagnostics, which identifies binding constraints and guides context-specific reforms.

6. Investment and Funding

• Meeting SDG targets will require a fourfold increase in WASH investments, which is beyond the capacity of most governments.
• Private capital and public-private partnerships (PPPs) are becoming increasingly important, especially in urban areas where cost recovery is more feasible.
• Better-targeted and more efficient investment is essential due to limited fiscal space in many countries.

Key Recommendations

• Shift toward coordinated, multisectoral investments to improve human development outcomes.
• Improve data collection and analysis to better understand spatial and social inequalities.
• Engage with local stakeholders and institutions to align policy with implementation and ensure accountability.
• Enhance the efficiency of resource allocation and prioritize investments in areas with the greatest need.
• Adopt a problem-driven approach to diagnostics, which identifies specific service delivery challenges and constraints.

Conclusion

The report underscores that the SDGs demand a more inclusive and equitable approach to WASH service delivery. It highlights the need for a deeper understanding of the political, institutional, and social contexts that shape service access and quality. While it does not offer one-size-fits-all solutions, it encourages a dialogue on how to rethink WASH strategies and work differently to address the challenges of inequality in service delivery. The insights from this initiative are critical for achieving the SDGs and improving the lives of the poor and vulnerable.
