Two studies on the effect of climate change on coffee production published recently give scientific evidence that highlights the need for sustainable coffee production in Uganda. This was revealed by the research partners and members of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).
A study by Alessandro Craparo and colleagues, reveals that at present climate change is already impacting Arabica coffee yields in the East African Highlands region.
The study observed that over the last 49 years, there has been a +1.42 °C increase in night temperatures, which has led to yield decrease in Arabica coffee of approximately 40 percent.
Every 1°C rise in minimum temperature will result in annual yield loss of roughly 60 percent of an average smallholder farmer’s current production in Tanzania. Although there are currently no country specific numbers,
