Manuel Sauri – CEO of Agua Segura
When we think about the importance of water for our lives and development, we likely picture rivers, seas, and lakes that provide us with nourishment, energy, and recreation. If we delve a bit deeper, we might also reflect on the significance of wetlands and ecosystems that help mitigate the effects of climate change, contributing their biodiversity and richness. However, there’s a place where nearly all of the planet’s liquid freshwater is found: beneath the earth. Groundwater is crucial to human society, and its protection and sustainable management are the foundation of any development strategy.
Access to safe water is a basic human right. We only need to recall the “water cycle” we learned in school to understand that what we do on the surface directly affects what happens below. If the water cycle doesn’t function properly, terrestrial ecosystems can’t sustain themselves, leading to climate variations that impact the levels of rivers, lakes, seas, and oceans. Groundwater is the backbone of drinking water supplies, sanitation systems, agriculture, industry, and ecosystems. If, for example, it’s depleted due to excessive irrigation pumping or contaminated by pesticides or hazardous substances, the availability of this essential public good for human life is severely compromised. This, in turn, triggers a chain of challenges, including the degradation of productive soils and the wealth they generate daily. Agriculture is the largest consumer of freshwater resources worldwide, and the ability to feed the growing global population depends heavily on this resource and the health of the land we cultivate, irrigate, and harvest.
According to the UN, to feed a global population that could reach 9 billion by 2050, food production must increase by 60%, and today, 40% of all irrigation water comes from aquifers. Therefore, to prevent groundwater depletion, sustainable policies must be adopted that provide information on its location, availability, and condition; focus on efficient resource management; and protect its quality to preserve its diverse functionality, adding value to the human and productive development of any community. Groundwater knows no borders, and a global, collaborative, and long-term perspective is necessary to address the challenges we face.
Another critical aspect is the importance of ecosystems in creating safe environments for life on the planet. Groundwater protects our coasts from seawater intrusion and plays a key role in mitigating climate change by safeguarding ecosystems such as wetlands and rivers. The water crisis has also exacerbated the aridity of some regions that now rely almost exclusively on groundwater for survival.
We’re talking about a hidden treasure beneath our feet that we must care for, monitor, and manage with great responsibility. It’s about making the invisible visible—the infinite value of our groundwater.
