The Scientists Fighting to Save Us From a World Without Coffee

Climate change is threatening your morning caffeine fix.

While Washington debates whether climate change is a hoax or an imminent threat, the world coffee industry is not waiting for the American government to take action to protect its business.

Coffee crops are under siege from deforestation, abnormally high temperatures, a lack of precipitation, and disease. The global market is heading for its fourth straight year of deficit, according to estimates from Rabobank International. At the same time, global demand for the beloved beverage is expected to reach an all-time high this year, led by demand from younger American consumers. Production will need to increase at least 50 percent by the middle of this century to keep pace with the demand, says Conservation International, an environmental organization. To cope, the industry is rushing to develop plants that can adapt with the changing environment.

Land suitable to grow the arabica beans favored by Starbucks Corp. and other specialty roasters will be cut in half worldwide by 2050, according to the World Coffee Research institute, a group sponsored by the industry. In Brazil’s Espirito Santo state, output has fallen precipitously, particularly for the robusta variety of coffee bean. In the last three years, the region has received just 50 percent of its average rainfall, while temperatures soared to 3 degrees Celsius above normal. “It was the worst drought in 80 years,” Romario Gava Ferrao, a researcher at the state-run research institute, Incaper, told Bloomberg. Some farmers have moved to other regions or have invested in other crops such as pepper, he said.

Hugo Ramos, a meteorologist at Incaper, isn’t sure if the warmer, dryer weather is a permanent change for the region. “We have to study more to understand what will happen in the next years.” The situation has become so dire that the nation is considering importing lower-quality robusta beans from Vietnam in order to meet demand, an option that has met strong opposition from local farmers.

Leaf rust, a fungal disease that affects both arabica and robusta plants, is also devastating the industry. About 18.2 million bags of coffee worth about $2.5 billion were lost to the disease from 2011 to 2016, according to WCR. The loss put 1.7 million people out of work. A warmer planet means producers will be forced to contend with more frequent threats to their beans.
