Overview

Here we provide outputs of the global simulation of water footprints of crops with a process-based gridded crop model ACEA (see model description in the references). The model is based on FAO’s AquaCrop and covers 175 widely-grown crops in the 1990–2019 period at a 5 arcminute resolution (10 x 10 km). We partition water footprints into green (water from precipitation) and blue (from irrigation or capillary rise) and differentiate between rainfed and irrigated production systems. The outputs cover several variables, including unit water footprints (expressed in m3 t-1 yr-1), water footprints of crop production (m3 yr-1), and crop water use (mm yr-1).

Version History

2025-05-16 (v3): new files added to provide global gridded datasets for all individual crops & years:

> unit_wf_175_crops_annual_1990_2019.zip – unit water footprints per crop in 1990–2019 for all combinations of production systems (rainfed, irrigated, total) with water types (green, blue, total)

> cwu_175_crops_annual_1990_2019.zip – same but for crop water use

> harvested_area_175_crops_annual_1990_2019.zip – rainfed, irrigated, and total harvested areas per crop in 1990–2019

> production_175_crops_annual_1990_2019.zip – same but for crop production

> classification_of_175_crops.csv – crop classification for user convenience, based on FAOSTAT


2024-02-28 (v2): new files added to provide representative data for the current state of water footprints:

> global_wf_175_crops_average_2010_2019.csv – global average values per crop over 2010–2019

> national_wf_175_crops_average_2010_2019.csv – same but for individual countries


2023-08-16 (v1): dataset uploaded for the first time (as described in the data descriptor paper)
