Pressure over water resources is expected to increase rapidly as a result of climate change and growing demand. Therefore, water shortages are expected in the near future. In this context, we need to develop and propose new methods, approaches, and tools to contribute to improving the management of groundwater resources under the current context of global change. This special issue comprises extended abstracts of the submitted contributions to the session HS8.2.1 (Groundwater management in the context of global change: integrating innovative approaches) organized in the General Assembly 2024 of the European Geosciences Union.
