Groundwater Cooperation Crucial for Global Water Security and Climate Resilience
Groundwater cooperation is essential for water security, climate resilience, food production, and sustainable management of shared aquifers across national borders.
Groundwater cooperation is becoming increasingly important as countries face growing water scarcity, climate change impacts, population growth, and rising demand for freshwater resources. As the world’s largest source of liquid freshwater, groundwater plays a vital role in sustaining communities, supporting agriculture, protecting ecosystems, and ensuring long-term water security.
Recognizing its global significance, leading international organizations are convening experts and policymakers to discuss how cooperation can improve groundwater governance and strengthen multilateral efforts for sustainable water management.
Why Groundwater Matters
Groundwater is the water stored beneath the Earth’s surface in soil, sand, and rock formations known as aquifers. It represents one of the most valuable natural resources on the planet.
Unlike surface water sources such as rivers and lakes, groundwater often remains available during droughts and periods of water stress, making it a critical buffer against climate variability.
Experts emphasize that protecting groundwater resources is essential for achieving sustainable development and ensuring water availability for future generations.
The World’s Largest Source of Freshwater
Groundwater accounts for the largest share of liquid freshwater available on Earth. Billions of people rely on groundwater every day for drinking water, sanitation, and domestic use.
Key benefits of groundwater include:
- Reliable drinking water supply
- Support for urban and rural communities
- Water availability during droughts
- Long-term freshwater storage
- Protection against climate-related water shortages
As global populations continue to grow, groundwater resources will become even more important in meeting future water demands.
Groundwater and Food Security
Agriculture remains one of the largest users of freshwater worldwide, and groundwater plays a critical role in food production.
Farmers depend on groundwater for:
- Crop irrigation
- Livestock production
- Agricultural resilience during dry seasons
- Protection against rainfall variability
Without sustainable groundwater management, agricultural productivity could decline, threatening food security and rural livelihoods.
Experts warn that excessive groundwater extraction in many regions is already placing significant pressure on aquifers, making cooperative management increasingly necessary.
Supporting Climate Change Adaptation
Climate change is altering rainfall patterns, increasing drought frequency, and intensifying water scarcity across many parts of the world.
Groundwater serves as an essential climate adaptation resource because it:
Provides Drought Resilience
Groundwater supplies remain available even when surface water resources decline.
Enhances Water Security
Stored groundwater offers a dependable source of freshwater during periods of climate uncertainty.
Supports Ecosystem Health
Many wetlands, rivers, and natural habitats depend on groundwater flows to maintain ecological balance.
Reduces Climate Vulnerability
Communities with secure groundwater resources are often better equipped to adapt to changing environmental conditions.
Experts increasingly view groundwater management as a cornerstone of climate resilience strategies.
Shared Aquifers and International Cooperation
One of the most important reasons why groundwater cooperation matters is that many aquifers extend across national borders.
These transboundary aquifers are shared by multiple countries, requiring cooperation to ensure:
- Fair and equitable water access
- Sustainable resource management
- Conflict prevention
- Long-term water security
- Environmental protection
Without coordinated policies, over-extraction or pollution in one country can negatively affect neighboring states that depend on the same groundwater system.
International cooperation therefore plays a crucial role in preventing disputes and promoting shared benefits.
Groundwater in Multilateral Processes
Groundwater is receiving increasing attention in global water governance discussions.
International organizations are working to strengthen:
- Groundwater monitoring
- Data sharing
- Policy coordination
- Scientific research
- Capacity building
These efforts aim to improve decision-making and ensure that groundwater resources remain available for future generations.
Experts argue that groundwater must be fully integrated into climate adaptation plans, sustainable development strategies, and international water agreements.
Global Experts to Discuss Groundwater Cooperation
To advance dialogue on this critical issue, leading international organizations are organizing the second webinar in the Groundwater Matters series.
Event Details
Title: Groundwater Matters for Cooperation and in Multilateral Processes
Date: 17 June
Time: 14:00–15:30 CEST
The webinar is being organized by:
- International Association of Hydrogeologists (IAH)
- UNESCO
- World Bank
- World Meteorological Organization (WMO)
- International Atomic Energy Agency (IAEA)
- UN-Water Expert Group on Groundwater
The event will bring together experts, policymakers, researchers, and practitioners to explore how groundwater cooperation can contribute to sustainable water management and international collaboration.
Strengthening Water Security Through Collaboration
Water security challenges are becoming increasingly complex due to climate change, urbanization, population growth, and environmental degradation.
Groundwater cooperation offers an opportunity to:
- Improve water governance
- Enhance climate resilience
- Support sustainable agriculture
- Protect ecosystems
- Promote regional stability
Experts believe that stronger collaboration among governments, international organizations, and local stakeholders will be essential for safeguarding groundwater resources in the coming decades.
Conclusion
Groundwater cooperation is fundamental to achieving global water security, climate resilience, and sustainable development. As the world’s largest source of liquid freshwater, groundwater supports billions of people, sustains food production, and protects ecosystems.
Because many aquifers cross national boundaries, international cooperation is critical for ensuring equitable access and responsible management. By strengthening multilateral engagement and promoting sustainable groundwater governance, countries can secure this invaluable resource for current and future generations.
