@lal_rattan@acharyaumesh7 There are limited studies on the carbon footprint (CFP) of coffee. The published literature demonstrates that coffee production (even with shade & organic systems) produces net carbon emissions. However, CFP ranges vary widely due to the use of different methodologies and tools.
@lal_rattan@acharyaumesh7 Most coffee CFP calculations omit key components that are critical to accurately assessing the CFP for coffee. Using a proposed new accounting system that includes missing components will result in more accurate figures than prior existing carbon estimation tools would generate.
@lal_rattan@acharyaumesh7 A revised approach to calculating carbon footprints that takes into account missing factors would provide coffee growers and roasters an improved protocol for identifying the best management practices for growing coffee.

A new research paper confirms that South Sudan is a center of evolutionary origin for Coffea arabica, and the plant populations in the area possess unique genetic diversity. The open-access paper can be found here: frontiersin.org/articles/10.33…

The paper is based on a study led by Dr. @KrishnanSarada, who was the lead author of the Global Coffee Conservation Strategy, co-published by World Coffee Research and the Crop Trust.

Another installment of Lessons from Plant Pandemics 🦠 //thread
The first ingredient in any epidemic? The pathogen. Coffee leaf rust is a dastardly disease of coffee caused by a fungus. Read more about it over at @apsapsnet.org/edcenter/disan…
Just like Covid19 is a disease caused by a viral pathogen called SARS-CoV-2, coffee leaf rust is a disease caused by the fungal pathogen H. vastatrix, just one in a massive family of crop-affecting rusts (like SARS-CoV-2 is one of a large family of coronaviruses)
A few highlights from the epic new report from the Columbia Center of Sustainable Investment: "Achieving Sustainable Development in the Coffee Sector" (thread)
