Why is water sustainability important?

No one on this earth does not need water. Approximately 71% of the Earth's surface is water-covered, and the oceans hold about 96.5% of all Earth's water. There is thus less than 5% fresh water available. Of the freshwater on Earth, much more is stored however in the ground than is available in rivers and lakes. As well known, water security is very much linked to energy and food security. Actions in any one particular area often can have effects in one or both of the other areas.

The problem is getting out of hand

Water is a precious resource, but can also be a threat. In some places, water is too much, too little and too dirty.  Now more than ever, clean water demand is rising, aquifers are being depleted and the threat of extreme weather is increasing.  Many cities are therefore nowadays struggling and many more are vulnerable with changing landscape around them.

Studies showed that there are at least three (3) elements for sustainable water, which are:

  • Resiliency,

  • Efficiency and

  • Quality

  • Resiliency

    The indexes include water space, green space, water-related disaster risk, flood risk, water balance and water reserves.

  • Efficiency

    The indexes include leakage, water charges, service continuity, wastewater reuse, metered water, drinking water, and sanitation.

  • Quality

    The indexes include drinking water, sanitation, treated wastewater, water-related disease, water pollution, and threatened freshwater species.

Water sustainability impacts the quality of life

Water sustainability does impact the quality of life. Cities need to satisfy their citizens’ water demand while increasing impermeable areas can potentially contribute to flooding. Taking into account unexpected circumstances, Modern planning practices have to be adaptive and risk-based for the mid- and long-term future. 

We, ECADIN Researchers, aim to be enablers for policymakers, planners, academia and scholars to collaborate in providing the modern planning in practices.
