The scarcity of water resources is a chronic problem in many southern regions of the European Union which, according to the forecasts of water resources models that incorporate the effects of climate change, will worsen and will spread to the northernmost regions.
These water resources maintain the environmental quality of rivers and wetlands, whose loss due to human activity is being very rapid, as reported in forums such as the Ramsar Convention. Therefore, prioritizing the environmental health of our aquatic ecosystems, as well as the multiple services they provide, is a strategy that could give good results in the medium and long term.
The generation of good quality water resources from unconventional sources in a sustainable and economically viable way is an option that is gaining more and more strength.
