Aragón (Spain), Herefordshire (United Kingdom) and Lower Saxony (Germany) have become areas with a very high density of intensive farms. An international investigation reveals the dynamics behind the expansion and the pollution of rivers, aquifers and even tap water that it brought along. 

Pork production for export has been one Spain and Germany’s big economic successes in this first quarter of the century. Chicken is a keystone seller for Tesco, the British supermarket giant. Cheap meat allows for large profits, but its low-cost production model, based on reducing costs specially on transport, has implied unprecedented farm concentration. The areas where these farms have been established are no longer able to cope with the water damage caused by animal excrements. An international investigation led by DATADISTA and The Guardian, disseminated in collaboration with elDiario.es and counting on the financing by Journalismfund.eu, locates areas with very high concentration of intensive livestock farming, digs into how these territories were grabbed by the meat business, big supermarkets, and world's pork megaproducers and unveils the degree to which water resources have been already damaged.


  • Premio Gabo 2023Journalists Ana Tudela and Antonio Delgado were part of a team who showed how areas of extremely high concentration of intensive macro-farms in Europe have polluted rivers, aquifers and even drinking water. They won the Premio Gabo 2023 in the category "Coverage". The Gabo Festival will be the opportunity to honour the best journalistic work in Ibero-America at the Gabo Award Ceremony.
  • This investigation won the 2023 Climate Journalism Award in the Data Category.
