In the Extremadura region of southern Spain, agriculture is responsible for nearly 90% of water use. With rains both seasonal and scarce, strong water management is key. We have worked with stakeholders throughout the local tomato supply chain to improve water use techniques. This has included installing new technologies such as buried irrigation, humidity sensors and flow meters. Additionally, we have analyzed the soil to optimize fertilizer use. As a result, water consumption has reduced from 79 m3 per tonne in 2012 to 46 m3 per tonne today. This has helped our Miajadas facility in Extremadura to become the first European food factory to achieve AWS gold-level certification in 2020.
