How to measure urban water security? An introduction to the Water Security Assessment Tool (WATSAT)

Abstract

The objective of the project was to develop a web-based digital tool called the Water Security Assessment Tool (WATSAT) to help city authorities and decision-makers make an objective evaluation of the water security situation in the city. It uses an indicator-based methodology that measures five distinct dimensions (broad elements) of water security: “Water supply and sanitation”, “Water productivity”, “Water-related disasters”, “Water environment”, and “Water governance”, which together culminate into a Water Security Index (WSI). The tool is developed based on the water security assessment framework developed by Babel, Dang, Sharma, and Shinde (2015). WATSAT results in a quantitative assessment of water security in a city, wherein the WSI provides an overall picture of the water security situation in a city, while the evaluation of the various dimensions helps identify areas of concern. WATSAT aids city authorities in having a holistic understanding of water security and interconnections of various factors affecting it and assists them in informed decision-making to arrive at system-based interventions to tackle water security threats in the cities.

Understanding contemporary challenges for water security in Ulaanbaatar, a semi-arid region in Mongolia

“…These assessments are based on the selection and categorisation of a set of indicators to create an operational water security index based on a weighted aggregate score from these indicators [19,[53][54][55]. Another tool for assess urban water security in Ulaanbaatar drawing from this study's findings could be the recently developed WATSAT tool [56] which enables city-planners and decisionmaking authorities to independently evaluate the water security situation in their city.…”
