Analysis and perspectives on water stress reduction: territorial implications and innovative approaches. – Ensuring water sustainability through technological innovation is crucial, especially for groundwater, a vital component linked to the hydrological cycle. It plays a pivotal role in supplying drinking water for various purposes, including agriculture and industry. Climate change pose significant threats to groundwater conservation, raising concerns about both quantity and quality with significant socio-economic implications. Effective preservation requires hydrogeological monitoring of underground basins, coupled with dynamic water balance modelling to provide predictive insights. These modern tools are essential for proper physical resource management. Implementing innovative technologies and strategic political and management planning for underground aquifers are imperative for initiating a robust program to mitigate risks and achieve a sustainable balance for this precious resource.
