Hydrogeology: Quo vadis…? A survey on the future of hydrogeology and seven ways forward in the light of global challenges
摘要
Groundwater faces increasing pressures from climate change, urbanization, land-use change, and emerging contaminants. To assess current challenges, future strategies, and priorities, the international survey “Hydrogeology: Quo vadis…?” gathered responses from the hydrogeology community across four continents. Key concerns included groundwater contamination, impeded recharge and water availability, insufficient regulation of new chemical substances, climate-related extremes, fragmented governance, and limited data accessibility. Strategic priorities focused on strengthening interdisciplinary cooperation, enhancing monitoring and data integration, ensuring sustainable resource allocation, and improving education and public awareness. However, a persistent gap between goal-setting and implementation emerged, driven by weak enforcement, governance and research silos, and resource constraints. To address this gap, seven possible ways forward are outlined: (1) strengthening implementation and enforcement, including improving legislation to protect groundwater; (2) improving cross-level and cross-sector coordination; (3) building networks; (4) investing in education and public engagement; (5) enhancing data integration; (6) tackling emerging challenges proactively; and (7) cultivating political will with long-term resources. The results provide a benchmark for global hydrogeology perspectives and a practical roadmap to advance more effective groundwater governance and protection.
