Water quality is influenced by urbanization. Nearly half of the global population lives in urban areas. By 2025, it will reach 60%, i.e. 5 billion people. This evolution is particularly important in underdeveloped countries as in 30 years it has increased by 350 %, versus 54% in developed countries.
Management of water is ineluctably affected by the North-South divide: every country encounters water issues, but only the most developed ones can solve them. In most of Third-World countries, only half of the needs in water are satisfied, and the lack of infrastructure to manage waste water and rain water is substantial. Hence, the proliferation of various diseases and the constant pollution of water by industrial and domestic products cannot be treated as well as in developed countries.
Urbanization and water have always been intimately linked, influencing one another. And the right balance between both has to be found in a constantly moving world.
