"The revelation shows water shortages, one of the most dangerous challenges the world faces, is far worse previously than thought. This causes migration."
According to World Economic Forum, water crisis is rated as one of the three great risks of harm to people and economy in the next decade, on par with climate change and migration.
Between 2000 and 2010, around 40 million people are estimated to have migrated out of drylands, most of them in Asia. Migration from rural areas to cities can be associated with population growth, environmental degradation, increased water stress and a lack of perspective. The perceived opportunities in cities pull young people from economically less developed regions. Living conditions will deteriorate, especially in the drier areas of the world.
