3 Trials and Tribulations Within the Hydrosocial Cycle

In the future, shifting precipitation patterns and the dwindling sustainability of groundwater aquifers will hit urban regions of Sub-Saharan Africa and Asia—home to 28 of 39 megacities with populations of 10 million or more—where the majority of people live in slums not served by piped water systems and generally do not have reliable access to WSS due to pollution, overexploited groundwater insufficient water infrastructures and ineffectual governments (Calow & Mason, 2014). By 2050, the Organisation of Economic Cooperation and Development (OECD), an intergovernmental organization with 35 members representing the wealthiest and most developed countries in the world, estimates that upwards 3.9 billion people, over 40 percent of global population, will live in areas of severe water stress.(Calow & Mason, 2014)
