The SCAA Chronicle had an interesting article on what sustainable coffee really is.
An excerpt from the article:
One reason it’s difficult to define sustainable coffee is, in truth, it’s hard to say decisively that coffee as an industry is not sustainable. We can certainly see sustainability challenges and even risks in the coffee sector. At a macro-level, the world is readying to feed a population of 9+ billion—demand for agricultural commodities is rising faster than supply, which may very well bleed over into coffee. Water and phosphorous resources are strained. Challenges for coffee farmers are well documented, namely around food insecurity, and the next generation of farmers are migrating to cities.
