Summary of "Argentina: Valuing Water"

Core Content

This report, Argentina: Valuing Water, is part of the World Bank's Water Security Diagnostic, aimed at assessing water security in Argentina and providing recommendations for a more sustainable and resilient water sector by 2030. It highlights the importance of water in Argentina's economic, social, and environmental development, as well as the challenges posed by climate change, water scarcity, and inadequate infrastructure.

Main Points

Water Security as a Priority: Water security—ensuring an acceptable, affordable, and sustainable supply of water for health, livelihoods, ecosystems, and production—is central to Argentina's sustainable development.
Economic Importance:
- Argentina is a major grain exporter and a net contributor to global food security.
- Agriculture accounts for 6% of GDP and 87% of the sector's value, with irrigation contributing 13% of the sector's value and generating $5.67 billion annually.
- Droughts can significantly impact GDP, with a 10% drop in productivity in key provinces representing a 0.7% drop in GDP.
Social and Health Impacts:
- 17% of Argentina's population lacks access to safely managed water, and more than double lack access to safely managed sanitation.
- Poor and vulnerable populations, especially in peri-urban areas, are most affected by these service gaps.
- Water quality issues pose public health risks and are exacerbated by climate change.
Environmental Considerations:
- Climate change is increasing the frequency and severity of floods and droughts.
- Environmental degradation, such as pollution and water overuse, affects water quality and limits recreational use of rivers like the La Plata.
- The report emphasizes the importance of the water cycle in linking resource management, service delivery, and risk mitigation.

Key Challenges

Water Scarcity and Droughts:
- Droughts are a growing threat, particularly in provinces like Buenos Aires, Santiago del Estero, Entre Ríos, Santa Fe, and Córdoba.
- Climate change is increasing the stress on water resources, making the need for adaptation more urgent.
Flood Risks:
- Floods affect both rural and urban populations, with significant impacts on social sectors and economic stability.
- Vulnerable communities, especially in low-income quintiles, are disproportionately affected.
Institutional and Policy Gaps:
- The water sector faces challenges in governance, infrastructure, and financing.
- There is a need for stronger institutions, better policies, and increased investments to improve water services and infrastructure.

Key Recommendations

Water Governance:
- Strengthen institutional frameworks and promote inclusive and efficient water services.
- Develop and implement comprehensive water policies that integrate climate change adaptation and mitigation.
Water Infrastructure:
- Invest in improving irrigation efficiency and expanding complementary irrigation to 4.7 million hectares.
- Enhance water supply and sanitation infrastructure, especially in underserved areas.
- Improve the National Water Network Information System (SNIH) and other monitoring tools.
Resilience Building:
- Develop strategies to manage water-related risks, including floods and droughts.
- Improve the resilience of agricultural production and other sectors that depend heavily on water.
Policy and Investment Integration:
- Align water investments with the 2030 Sustainable Development Goals (SDGs).
- Leverage the World Bank's expertise and partnerships to support these initiatives.

Key Partners and Support

The report was supported by the Global Water Security & Sanitation Partnership (GWSP), a multidonor trust fund.
It was developed in collaboration with various institutions, including the Universidad de La Plata, CUNY, UNESCO, FAO, and others.
The report was prepared with the support of the World Bank's Global Practices, including Water Resources Management, Water Supply and Sanitation, Resilience, and others.

Methodology and Contributions

The report uses a conceptual framework to evaluate the economic, social, and environmental outcomes of water.
It includes:
- Hydrological and hydro-economic modeling with climate change projections.
- A public expenditure review of water and sanitation services.
- An updated analysis of irrigation viability in Argentina.
- Compilation of water quality data and initial steps toward assessing surface water quality.

Conclusion

The Valuing Water report underscores the critical role of water in Argentina's development and the need for integrated, forward-looking strategies to address water security challenges. It provides a comprehensive diagnostic of the current water sector and outlines actionable recommendations to enhance resilience, improve service delivery, and support sustainable economic growth by 2030.
