Current United Nations predictions estimate that the world population will reach 9 billion in 2050. The exponential growth in population and the more intensive use of water per capita are among the leading key drivers behind hydrologic change and its impact. It is a huge challenge on an already resource-limited planet to meet the various needs of the people, especially of those who already lack access to clean water.
