How Sustainability Correlates to Household Water Security Disparity

In order to evaluate household water security disparity and the variables influencing it, a group of scientists from Cardiff, Birmingham, North Carolina and Midwestern Universities have examined over 7,600 houses in 22 low- and middle-income countries.

According to the academics, the “Kuznets Curve,” which is used to outline the route of economic development, is mimicked by this water security inequality.

The Kuznets Curve postulates that when economies first start to grow, market forces intensify economic disparity; then over time, the same forces are shown to reduce it. A similar model was then created about 30 years later which substitutes economic disparity for environmental pollution. Researchers found that it is possible to demonstrate that inequality begins to grows before decreasing by utilising water security disparity as the dependent variable.

Generally, people believe that there is a positive correlation between pollution and economic disparity, however “non-economic factors such as sustainable development levels may also be able to indicate or alter the distribution of resources and services”.
Dr Feng Mao, lead author of the study, said that “This research extends the conventional Kuznets Curve concept and encourages a more general rethink of development beyond economic terms.”

David Hannah, Professor of Hydrology, added that this discovery may have “practical implications for understanding and taking action on water security to achieve fairer, more inclusive and sustainable development of water for all.”
