Agri-Food System Water Use Database
2023
International Food Policy Research Institute
This database provides information about the amount of water use in agriculture food systems covering all sectors from farming to food processing industries. The data are presented at the country level with sectoral disaggregation following the Nexus Social Accounting Matrix (SAM) sectoral specifications. The database also differentiates the type of water in each sector based on water sources. The green water refers to type of water originated from precipitation or rain, while the blue water refers to all water that comes from irrigation covering both surface and groundwater. Both types of water are consumed by plants or animals during the production process. The grey water on the other hand is the amount of water generated as an implication from production activities that cause the water polluted. Since it has loads of pollutants created from production activities, this type of water can be seen as a waste in the whole production system.
