Water is one of the most precious natural resources of our planet. Only 2% of the world’s water resources are made up of freshwater. This scarce resource however plays a crucial role in all segments of nature, society and economy. In view of the projected growth in popular demand for water and an accelerating climate change it is expected that by 2030 some 40% of the world’s population will suffer from water shortages. Europe and Hungary, too, will be affected: access to water is likely to become a fundamental issue of prosperity and peace at the individual and national level alike.
