Climate change and coffee: Blog Action Day

by on October 15, 2009

The theme this year for Blog Action Day is climate change, and it is an extremely relevant topic for coffee. More people rely on agriculture for a living than any other occupation, with millions of them being small coffee growers. As an agricultural crop, coffee is, of course, profoundly affected by weather and climate.

Examining crop and climate models, experts at the International Center for Tropical Agriculture (CIAT) have a prediction about the future of coffee in several Latin American countries: “without adaptation, the prospects are bleak.”  They go on to note adaptation must being now and,

“…planting shade trees today can buffer the impacts of climate change and buy a farmer a couple of extra decades to diversify production.”

I’ve written a number of posts on various aspects of climate change and coffee. I’ll provide a list here, as well as a list of other links and resources.

  • Coffee growing and climate change. A brief overview.
  • Coffee, climate change, and Rainforest Alliance. How Rainforest Alliance is evaluating criteria to choose which improve carbon storage and mitigate climate change as an add-on to their certification.
  • Shade coffee buffers against climate change. Research revealing that shade cover helps to moderate changes in microclimates on coffee farms. with the potential to mitigate climate change impacts.
  • Climate change and coffee pests. This posts discusses recent research on the coffee berry borer, and potential changes (increases) in this small beetle, one of the world’s worst coffee pests. Authors note that shade trees can help mitigate temperature increases and perhaps reduce the impact of this pest.
  • Coffee farms and carbon sequestration. How coffee farms can serve to mitigate climate change via carbon sequestration. Includes a number of estimates on how much carbon can be stored on coffee farms, and a list of additional reading.
  • Carbon credits with coffee: a how-to guide. Describes a document that outlines methods for verifying carbon stored on coffee farms and a mechanism for producers to receive payments for carbon credits.
