A study conducted by the University of Southern Queensland in collaboration with the World Meteorological Organisation and the International Centre for Tropical Agriculture has found that climate change is impacting the production of robusta coffee, a variety that accounts for nearly 40% of the world's coffee supply. The research, which analyzed data from nearly 800 robusta coffee farms across South East Asia, discovered that the crop performs best at an average temperature of 20.5 degrees Celsius, rather than the previously assumed optimal range of 22-28 degrees Celsius. Each degree above 20.5 degrees results in a yield decline of around 14 per cent, indicating that robusta coffee is more temperature-sensitive than previously believed. The findings have implications for coffee production and the livelihoods of millions of farmers in South East Asia.

It's known - and named - for its robust nature, but a University of Southern Queensland (USQ) investigation has found climate change is impacting production of popular coffee bean variety, robusta. Millions of farmers grow robusta coffee around the world, supplying nearly 40 per cent of the world's coffee - second only to the arabica bean. As part of the 'De Risk South East Asia' collaboration project with the World Meteorological Organisation and the International Centre for Tropical Agriculture, USQ researchers are looking at ways to increase the resilience of agricultural producers in the region, including the impact of climate change on coffee growers. Dr Jarrod Kath from USQ's Centre for Applied Climate Sciences said the project used a decade of yield observations from nearly 800 robusta coffee farms across South East Asia in conjunction with rain and temperature data to find the perfect temperature range for peak production. Robusta is a common crop in South East Asia due to ...
