In the lush coffee-growing region of Huatusco, Veracruz, a groundbreaking study is shedding light on the often-overlooked water footprint of coffee production. Lead researcher Sergio Sánchez Hernández has made significant strides in understanding how much water goes into cultivating and processing one of the world’s favorite beverages—Coffea arabica L.
Using the innovative CROPWAT 8.0 software developed by the Food and Agriculture Organization (FAO), Sánchez and his team calculated a staggering virtual water footprint of 1132.73 cubic meters per kilogram of parchment coffee. This figure includes both green and gray water, with the latter accounting for the water required to dilute pollutants generated during processing. “Our findings are a wake-up call,” Sánchez noted. “They highlight the pressing need for sustainable practices in coffee farming, especially in regions where water resources are becoming increasingly scarce.”
The research reveals that the green and gray virtual footprint for coffee production alone stands at 977.61 m3/kg. When it comes to the wet processing phase, where cherries are transformed into dry parchment coffee, two of the five mills surveyed reported water expenditures of 566 m3/kg and 162 m3/kg, respectively. The average consumption across the mills was 155.13 m3/kg. The striking takeaway? The blue virtual footprint—representing water sourced from irrigation—is nonexistent in this area, as local farmers typically rely on rainfall.
This pioneering study is more than just a collection of numbers. It serves as a crucial reminder of the environmental impacts tied to coffee production, which is particularly pertinent given the growing global demand for this beloved brew. As the coffee industry faces mounting pressure from consumers who are becoming increasingly mindful of sustainability, the data presented by Sánchez could spur a shift towards more responsible farming practices.
Sánchez emphasized the importance of awareness, stating, “Understanding our virtual water footprint is the first step in making informed decisions that can lead to more sustainable coffee production.” This sentiment resonates deeply as coffee producers, processors, and consumers alike grapple with the implications of their choices on water resources.
With this research published in the journal ‘Tropical and Subtropical Agroecosystems’, it opens the door for further studies in the region. It’s a clarion call for agribusinesses to innovate and adapt, potentially leading to the development of new techniques that minimize water usage while maintaining product quality.
As Huatusco’s coffee producers look to the future, they may find themselves at a crossroads—one that could redefine their practices and ensure that coffee remains not just a staple of our mornings, but a sustainable crop for generations to come.
