Freshwater sustainability. Secrets that became open: the previously unknown or underestimated facts and principles

Freshwater sustainability. Secrets that became open: the previously unknown or underestimated facts and principles relevant to water quality.
New conceptualization: how ecosystems improve water quality. A series of publications that provided a clear scientific analysis and picture.

The scientific problem and its scientific solution.

There is a water crisis: a deficit in freshwater supply in many countries. In future, the deficit will increase. Necessity for a solution of the problem of food supply, and the problem of energy supply will increase the deficit even to a greater extent. 1,000 litres of water is used to produce one kilogram of wheat.  Moreover, an additional problem is that what we need is  more than just some amount of water. We need not only some amount of water but also we want the water to be of proper quality. It is really very important that we need water of good quality. Is there any solution at all? One of prerequisites in finding a way out is to get a better insight into how the proper water quality is formed by the natural forces of aquatic ecosystems. An innovative analysis was made in a series of scientific publications which provide a clear system of factors and processes that lead to improving water quality (water self-purification). To exploit this system and to benefit from it, we need to understand it.
