According to a research published in Science Advances, at least 60% of coffee types are threatened with extinction, 45% are not in any germplasm collection, and 28% are unknown to exist in any protected region. Coffee conservation measures currently in place are insufficient.
In addition, a recent research published in the journal PLOS One predicts how the growing circumstances of three common crops (coffee, cashews, and avocados) will alter over the next 30 years.
Coffee is the most affected by global warming of the three crops: the study forecasts that the number of regions where coffee can be cultivated would decrease across the board by 2050. Higher yearly temperatures in coffee-producing nations such as Brazil are the primary cause of the reduction.
Arabica coffee is one of the two major plants from which coffee beans are harvested. This plant developed in Ethiopia’s high-altitude tropics and is extremely vulnerable to climate change.
However, how can coffee bean production continue in the face of global warming? Scientists from the Royal Botanic Gardens say in a recent analysis published in Nature Plants that Liberian coffee, previously the second most traded coffee crop type, might re-emerge to help maintain coffee production in a changing environment.
According to the authors, there are three approaches to assist coffee farming in adapting to climate change: Relocate coffee manufacturing to more favourable locations. Adapt coffee cultivation practises. Creating coffee crops that are more resistant to future climate change. They believe that switching crop kinds is the least disruptive and most cost-effective option.
The Liberian coffee species was formerly widely farmed in the second half of the nineteenth century because it was prolific, resistant to pests and illnesses, and could thrive in warmer terrain that Arabica coffee could not. However, interest in this coffee faded in the early twentieth century due to variable quality and profitability, among other difficulties.
According to the writers, the first Liberian coffee fruit and seeds were difficult to prepare and hence unpopular with coffee dealers. Across contrast, excelsa coffee (a Liberian variety of coffee) has recently expanded in Africa. This coffee bean and fruit are comparable to Arabica in that they create a moderate and smooth coffee with little acidity and bitterness, but they have the same amount of caffeine.
Researchers think that under a changing environment, at a lower altitude and warmer temperature than Arabica, the Liberian species has the potential to produce a commercially viable and perhaps more valuable coffee.
A cup of comfort, a burst of vitality when we need it most. However, coffee is both influencing and being influenced by climate change and global warming. A two-cup-a-day habit would add 311 kilogrammes (685 pounds) to your carbon footprint.
