How can you assess water risk for a manufacturing firm using geospatial data?

• A. Focus on desalination costs only.
• B. Ignore regulatory rights.
• C. Map water stress indicators, watershed boundaries, facility water intakes, regulatory rights, and model drought scenarios and supply disruption risk.
• D. Model only historical rainfall.

Answer: (C)

Assessing water risk with geospatial data means linking where a facility sits to the availability, governance, and variability of water in that location. The best option does exactly that by mapping water stress indicators, watershed boundaries, facility water intakes, regulatory rights, and by modeling drought scenarios and supply disruption risk. This combination captures how much water is realistically accessible at a site, who has legal access to it, and how future droughts or interruptions could affect supply. For example, a plant in a water-stressed basin with certain regulatory allocations may face competing demands or permit constraints during drought, making its water risk higher than a plant in a more abundant area. Using layered GIS data allows you to visualize exposures, compare sites, and run scenario analyses to plan for water efficiency, diversification of supplies, or relocation as needed. In contrast, focusing only on desalination costs misses supply reliability and legal access, ignoring regulatory rights leaves legal constraints unaddressed, and modeling only historical rainfall fails to capture future climate variability and disruption risks.
