World Water Day is celebrated every March 22 to remember the relevance of this essential liquid. Despite the fact that all social and economic activities depend heavily on the supply of fresh water and its quality, 2,200,000 people live without access to drinking water.
This celebration aims to raise awareness about the global water crisis and the need to seek measures to address it so that we achieve Sustainable Development Goal No. 6: Water and sanitation for all by 2030.
This 2022 the focus of attention is on groundwater, invisible water whose effects can be seen everywhere. This is water found underground, in aquifers (formations of rocks, sand and gravel that contain significant amounts of water). After feeding springs, rivers, lakes, and wetlands, groundwater eventually seeps into the oceans. Its main source of recharge is rain and snow that infiltrate the ground and can be extracted to the surface by means of pumps and wells.
Life would not be possible without them. Most of the arid areas of the planet depend entirely on this resource, which supplies a large proportion of the water we use for consumption, sanitation, food production and industrial processes.
Likewise, groundwater is decisive for the proper functioning of ecosystems, such as wetlands and rivers.
That is why we must protect them from overexploitation - extracting more water than is recharged with rain and snow - and the pollution that currently haunts them, since it can lead to the depletion of this resource, making its treatment more expensive. and regeneration and until the cessation of its use.
This year, let us claim the study, protection and use of groundwater in a sustainable way to survive climate change and meet the needs of a constantly growing population.
