NERC EDS Environmental Information Data Centre 10.5285/45cb218c-b050-4ee8-8c87-73d3895a111f Gridded data of water debt for year 2000. The water debt expresses the number of years required by the hydrological cycle to replenish the water source (soil moisture, surface water, ground water) that have been used to accomplish the annual production of nine major crops. The considered crops are: wheat, maize, rice, soybean, sugar cane, sugar beet, cotton, barley, sorghum.

The annual renewability rate is calculated as a long-term average along the period 1987–2013. In this way, we obtain an average measure of the water availability in the cell, which smooths out potential extremely dry or extremely wet years. The water footprint (WF) estimates are computed for year 2000 because this is the most referenced year in agricultural datasets available in the literature. The WFs, cr, l estimate is obtained as the product of the local crop water footprint (CWF) by source, (CWFs, cr, l, expressed in cubic meters per ton of crop), and the annual crop production (Pr), (Pcr, l, expressed in tons of crop). The total WD of the sources, arising from all the crops cultivated in the grid cell, WDs, l, equals the sum of debts generated by each crop. Owing to the simultaneous replenishment of soil water, surface water, and groundwater by precipitation, the crop WD across the threes sources, WDcr, l, is given by the maximum WDs, l, cr value across sources s.
