Coffee, a victim of climate change: Crops at risk due to ‘excessive’ heat, study warns

he human-induced climate change It can be grown on land where coffee, an important crop for the economy of the producing region, is grown.

This has been warned by research published in more climatesexplains that while coffee trees are sensitive to climate variability and change, the impact of simultaneous climate risks occurring in multiple key regions for coffee production is unknown.

Research led by Doug Richardson of CSIRO Oceans & Atmosphere, Australia, to better understand how large-scale weather events such as the El Niño Southern Oscillation (ENSO) can cause coffee crop failures in multiple countries simultaneously conducted a systematic analysis. of climate disasters and compound events in coffee-growing regions from 1980 to 2020.

They identified 12 climate risks that threaten coffee crops in 12 major producing countries. The maximum temperature a coffee tree can withstand.

They found an increase in the number of climate disasters and complex events in all coffee-growing regions between 1980 and 2020. They point out that more research is needed to find out if it can be mitigated.

According to the authors, “These results suggest that, at both global and regional scales, El Niño is the main way to explain the variability of complex climate events. , indicating a systemic risk to coffee production rather than a local risk.”

“As with other crops, simultaneous crop failures pose systemic risks to the global coffee trade,” they added. Given that climate change projections indicate that warming in the tropics is likely to continue, coffee production is likely to experience continued systemic shocks in response to spatially exacerbating climate risks. I believe that you may experience “

The authors conclude: “Since 1980, global coffee production has been increasingly at risk of synchronous crop failures, which may be due to climate risks affecting several key growing regions simultaneously.” points out.
