Biodiversité

Watercourses are intensively managed in many areas around the world and face serious problems such as increasing population in urban areas i.e. over 50% of the global population lives in cites. In short, and quoting recent papers published, it is expected that the number of people affected by organic pollution will increase from 1.2 billion in 2000 to 2.5 billion in 2050. Wastewater discharges from cities, specially megacities, and intensive livestock due to increased demand on food supply can be considered as main sources of pollution of our rivers and groundwaters.
