World Water Day is celebrated today, this year under the theme "Groundwater: making the invisible visible". Invisible groundwater is found underground, in aquifers, and is decisive for the proper functioning of "Groundwater Dependent Ecosystems". If you want to know an exceptional case of a terrestrial ecosystem of this type in the arid Mediterranean areas, you can visit our "Climate Change Route", in the coastal plain of the Cabo de Gata-Nijar Natural Park. Through it you can discover how these ecosystems work, and the impact that climate change may have on them and on groundwater.
In this link you will find more information about this route and its relationship with groundwater.
