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.\n\nThe 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).\n\nThe 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.\n\nOwing 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.","metadataDate":"2026-06-29T16:35:29","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/45cb218c-b050-4ee8-8c87-73d3895a111f","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/45cb218c-b050-4ee8-8c87-73d3895a111f.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Dalin","givenName":"C.","organisationName":"University College London","organisationIdentifier":"https://ror.org/02jx3x895","role":"pointOfContact","email":"c.dalin@ucl.ac.uk","fullName":"Dalin, C.","pointOfContact":"University College London"}],"publicationDate":"2023-01-26T00:00:00.000Z","publishers":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"relationships":[{"relation":"http://purl.org/dc/terms/relation","target":"76f8c5c0-6dde-407a-9710-2bca2e041512"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/45cb218c-b050-4ee8-8c87-73d3895a111f"},{"code":"10.5285/45cb218c-b050-4ee8-8c87-73d3895a111f","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Tuninetti","givenName":"M.","organisationName":"Politecnico di Torino ","organisationIdentifier":"https://ror.org/00bgk9508","role":"author","email":"marta.tuninetti@polito.it","nameIdentifier":"https://orcid.org/0000-0003-2619-8783","address":{"country":"Italy"},"fullName":"Tuninetti, M."},{"familyName":"Tamea","givenName":"S.","organisationName":"Politecnico di Torino","organisationIdentifier":"https://ror.org/00bgk9508","role":"author","email":"stefania.tamea@polito.it","nameIdentifier":"https://orcid.org/0000-0001-6388-3283","address":{"country":" Italy"},"fullName":"Tamea, S."},{"familyName":"Dalin","givenName":"C.","organisationName":"University College London","organisationIdentifier":"https://ror.org/02jx3x895","role":"author","email":"c.dalin@ucl.ac.uk","nameIdentifier":"https://orcid.org/0000-0002-2123-9622","address":{"country":"UK"},"fullName":"Dalin, C."},{"organisationName":"Natural Environment Research Council","organisationIdentifier":"https://ror.org/02b5d8509","role":"rightsHolder"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"familyName":"Dalin","givenName":"C.","organisationName":"University College London","organisationIdentifier":"https://ror.org/02jx3x895","role":"pointOfContact","email":"c.dalin@ucl.ac.uk","fullName":"Dalin, C.","pointOfContact":"University College London"}],"rightsHolders":[{"organisationName":"Natural Environment Research Council","organisationIdentifier":"https://ror.org/02b5d8509","role":"rightsHolder"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["grid"],"spatialResolutions":[{"distance":"6548","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2000-01-01","end":"2000-12-31"}],"title":"Water debt for the annual production of nine major crops globally at 5 arcmin resolution for the year 2000","topicCategories":[{"value":"inlandWaters","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/inlandWaters"},{"value":"farming","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/farming"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/9","http://onto.nerc.ac.uk/CEHMD/topic/18"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/45cb218c-b050-4ee8-8c87-73d3895a111f","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}]}
