Water science is essential for understanding and managing groundwater resources. It provides knowledge that should be accessible to all, especially those without access. It is the basis for agricultural self-sufficiency, health, and dignity. Our experience recovering wells and water bodies corroborates its importance in facing droughts with sustainable facilities.

The heat absorbed by cities affects the health of their inhabitants, alters local weather, and pollutes water. Fighting this phenomenon is possible and necessary for a future in which more than 70% of the population will live in cities. Bringing nature back into the asphalt and concrete is the solution.

Recycling plastic waste to build schools and sanitation facilities introduces a valuable environmental and educational factor. In one of the most neglected areas of Côte d'Ivoire, we are collaborating on an innovative project to reverse the loss of quality education for young people, the basis for curbing migration.

Obtaining data on the water status at a given time and place is crucial for effective management. New technologies make it possible to develop transboundary monitoring programs that disseminate scientific knowledge, promote a common understanding of the problems, and convince us that we can do better together.

The IPCC forecasts continue to be fulfilled, and droughts are affecting regions where they were rare. The Mediterranean Basin, especially in its western area, is experiencing an exceptional lack of rainfall. A new climatic frontier is emerging there, and the solutions generated will be of utmost importance for future water management on Earth.

Healthy soil is the best tool for addressing the climate crisis and food insecurity. Regenerative agriculture and proper water management make it possible to reverse the alarming deterioration of agricultural land worldwide. It is a critical element in the fight against desertification and the empowerment of the most disadvantaged farmers.

The pollution of water by intensive agriculture and livestock farming has a high health and environmental cost. This problem's solution is as complex as it is urgent. We must be able to provide food security for 8 billion people without damaging the environment. Water free of pollutants will indicate that we have achieved this.

The search for solutions to the pollution caused by mercury used in artisanal gold mining reveals how difficult it is to deal with a semi-clandestine activity widespread in many developing countries, often generating an informal economy. Mercury causes death and keeps more than one million people worldwide chronically and silently ill. Developing global ethics for the gold market is essential to end dumping and provide justice for miners.
