The Water-Energy-Food-Ecosystem (WEFE) Nexus advocates for integrated management to address interconnected challenges, particularly in water-scarce regions
What we do
The Knowledge Hub for Water supports informed decision-making by EU policymakers and stakeholders by:
- Assessing and disseminating high-quality knowledge on water resources availability and quality, leveraging the JRC's expertise
- Analyzing data and research on water resources, including water scarcity, pollution, and ecosystems, to identify solutions for water resilience and climate adaptation
- Bringing together scientific evidence to address the interlinkages of water with energy, food and ecosystems, and to promote a comprehensive approach to water management
- Providing scientific support and enhancing the knowledge base, through the development of tools, reports and analyses on key topics such as water balance, nutrient pollution, and nature-based solutions.
