Methodology to Estimate Water Stress

The Stockholm Environment Institute presents an updated computational method and a corresponding WEAP tool plugin to estimate seasonal water stress by spatially separating regions to avoid double-counting freshwater resources.

• The research introduces an updated computational method for the spatial separation of regions to prevent the double-counting of freshwater resources, which enhances the consistency of water estimates across various geographic levels.
• A Water Stress Plugin for the Water Evaluation and Planning System (WEAP) was developed to implement this methodology across various management and climate scenarios, allowing water managers to analyze water supply by season and sub-basin.
• The methodology supports UN Sustainable Development Goal Target 6.4, which focuses on reducing water scarcity through increased water use efficiency, noting that regional water stress disparities are often hidden by national averages in larger countries.
