The water footprint of Spanish grapefruit production has decreased by 36.9% over the past 30 years

Spain’s pomelo has managed to reduce its water footprint to 203 m³/t, positioning itself as the fruit with the lowest water footprint among all the fruits grown in the country, according to the Water footprint of Spanish grapefruit production report produced by the Interprofessional Lemon and Grapefruit Association (AILIMPO).

“Grapefruit cultivation is an example of how advances in irrigation and fertilization have optimized water use and management while increasing farm productivity over the past 30 years. to achieve higher production per amount of water used.”

“The calculation of the water footprint of a crop is part of AILIMPO’s sustainability policy in the environmental field, aimed at aligning with points 6 and 12 of the United Nations Sustainable Development Goals (SDGs) ( UN) to ensure the availability and sustainable management of water and sanitation. for all, and to promote responsible consumption.”

This innovative work carried out by the interprofessional organization has followed the methodology established by the Water Footprint Network (WFN), a world reference organization, and offers information on the water footprint of the grapefruit produced in Spain by province. In addition, the data obtained was compared with information from other years to see the evolution of the water footprint of pomelo over the last 30 years and to compare it to the footprint of other fruits.

The report quantifies the water footprint of Spanish grapefruit production at around 203 m³/t. Its blue water footprint was 79 m³/t, its green water footprint 54 m³/t and its gray water footprint 70 m³/t.

However, despite the positive data collected in the report, Spanish grapefruit growers continue to work to further reduce their water footprint, increasing investment in precision farming technologies to maximize productivity and minimize the use of water. water with different techniques, such as monitoring water in soils, placing padded plastics in crop lines, covering irrigation ponds and reducing the use of inputs, among others.
