Objective: To develop a high resolution dataset on physical, regulatory and reputational Water Risks for all sub-basins in Spain to be incorporated in the WWF Water Risk Filter 5.0, released in November 2018.

How we did it: A data gathering process took place first to collect data for 32 indicators on water scarcity, droughts, climate change, floods, quality, regulatory or reputational risks from official sources like the Spanish Ministry of Environment, National Drought Plans, Climate Change studies from the National Hydrographic centre and from the River Basin Management Plans (RBMP) from 17 River Basin Authorities in Spain. Description of data sources can be found here. Next step was to use Geographic Information Systems (GIS) to perform spatial integration of data from different sources to the WWF Water Risk Filter sub-basin delineation. The former sub-basin delineation was the one developed by Hydrosheds at its level 7 (with 256 sub-basins in Spain) and the data was integrated to the sub-basin delineation of Hydrosheds level 12 (more than 5000 sub-basins in Spain).
