That paper presented 6 recommendations “to support action by coffee stakeholders committed to increasing water security at origin”. I want to highlight one of the key SCA recommendations, and how it links to an exciting new report on water security.
The Measure of Coffee’s Water Footprint Needs to Be Revised
This 2003 study on coffee’s water footprint reported that it requires 140 liters of water to produce one cup of coffee. This metric is quoted so frequently (including by this blog) that it’s almost assumed to be a fact.
However, the study needs a critical review because it is based on some critical conceptual and methodological flaws. These flaws distort our understanding of coffee’s impact on water resources, and may mislead management and policy decisions within the coffee industry.
