The World Water Map Insights: visualizing global water demand and supply

Together with National Geographic and ESRI, we have developed the World Water Map: insights (https://livingatlas.arcgis.com/wwm-insights/) which provides modelled historical, current, and projected data of freshwater availability by source and use by sector to inform research, conservation, policy, and journalism.

This World Water Map insights provides robust open-source data sets and visualization of freshwater supply and demand that can be queried by source, sector, region and country, and by past, present, and projected future climate models. Users can gather data and create visualizations that inform research and tell stories of freshwater use, investigate what’s driving demand, and inspire sustainable adaptations and solutions.

The ‘insights Version’ compiles 40+ years of hydrological data from the global hydrological model PCR-GLOBWB 2, a grid-based global hydrology and water resources model and GRACE satellite data to chart global freshwater supply and demand to a scale of 100 square kilometres.

This service allows users to make data summaries, obtain time series data and acquire direct access to state-of-the-art climate projections and large-scale hydrological data that is otherwise not accessible for a larger scientific and policy community.
