Sips: Site updates
First, a general housekeeping update. A couple months ago, I had to re-do the appearance of C&C due to a theme implosion. The temporary one was awful, but I’ve now tidied things up considerably. There are no doubt still a fair number of startling font sizes, misaligned bullet points, peculiar spacing, and the like, but progress has been made. As I worked on code, I also edited and refreshed posts and links. A lot of this would not be obvious unless you came upon a post in which I made updates. Thus, I will provide some highlights by resurrecting the “Sips” news briefs, and link to the older material. I’ll begin with research that has been highlighted in the excellent Daily Coffee News by Roast Magazine.
- Daily Coffee News had a story (January 2025) about recent research confirming that the fungicides used to combat coffee leaf rust (Hemileia vastatrix), known as “la roya”, have health risks to farm workers applying them to coffee in Brazil. Full use of personal protective equipment was reported by only 23% of farm workers, and health impacts revealed disruption to endocrine and metabolic functions. My posts on coffee leaf rust include this overview of the disease, the impact it has had on organic coffee, and other overall impacts. The study summarized by Daily Coffee News is cited below, and is open access.
- Sticking with Brazil, the journal Nature Conservation (January 2026, citation below) published a lengthy and detailed review of the dire habitat destruction in the Brazilian cerrado region. I wrote an overview of coffee growing in the Brazilian cerrado, and in the ensuing years the crisis has grown. Over 55% of the native vegetation has now been destroyed. Agricultural expansion, especially in the coffee growing regions, is an important reason, although coffee is not the only agricultural product grown there. The paper provides an excellent analysis of the biodiversity of the area, which unique species are at risk, the extent and source of threats, impediments to conservation, etc.
- Although arabica coffee is self-pollinating, cross-pollination by insects improves fruit set and yields. I’ve written several posts on this topic, including how coffee grown in shade provides habitat for pollinators, how shade coffee specifically benefits suites of bees in Mexico, and even the status of bees as pollinators of robusta coffee in India. This story, again at Daily Coffee News (January 2026) and featuring Brazilian research, summarizes the use of managed colonies of a species of stingless bees on sun coffee farms, their impact on yield (it increased), and the uptake (traces were found) in coffee leaves, pollen and nectar of neonicotinoid pesticide applied to the soil (citation below). The Daily Coffee News story also referenced another meta-study (2022) of the impacts of bees and other pollinators on coffee yield worldwide. I’ve included that citation below as well.
- I have also written an overview of coffee growing in China, as well as an update. Daily Coffee News (Janaury 2026) summarized how models utilizing machine learning can analyze satelite images to map land growing coffee. Also cited below.
