Arabica coffee Endangered in 70 Years

Earth's average temperature increases of about 0, 74 degrees Celsius lasting impact on the ability of living organisms on Earth. One of the rising world temperatures will affect the population duni arabica coffee.

LONDON, KOMPAS.com? The study, conducted by scientists from the Royal Botanic Gardens, Kew (UK), and Ethiopia, reported that Arabica coffee (Coffea arabica) endangered wild in 70 years because of climate change. The study results were published in the journal PLoS ONE, Wednesday (11/07/2012).

"Worst case scenario, as obtained from our analysis, wild arabica be extinct by 2080. This should be a warning to policy makers against the vulnerability of this species," said Justin Moat, Head of Spatial Information in the Royal Botanic Garden, which is involved in the research.

Arabica coffee is important for the survival of wild coffee industry because genetic diversity owned. Arabica grown in plantations is fairly poor will have less genetic diversity that resilience to climate change and other problems, such as pests and diseases.

Extinction of arabica not only costly in terms of biodiversity. Extinction also affected economically because coffee is the most traded commodity after oil, and a source of income for some countries, such as Ethiopia.

Conclusion endangerment arabica coffee obtained from computer modeling. Data modeling material obtained from the museum (including herbarium) and field. This is the first study to measure the impact of climate change on coffee.

Two analyzes were conducted in the local and regional study. The study was conducted by comparing the spread of Arabica coffee today and that predicted by the year 2080. Three time intervals specified for analysis, ie 2020, 2050, and 2080.

The results of the analysis revealed that locally, the reduction of arabica coffee distribution locally is 65 percent-99, 7 percent. Meanwhile, the regional analysis shows that the distribution of the reduction was 38 percent-90 percent.

The threat of climate change on coffee may be worse. This analysis does not yet include the factors of deforestation around the habitat of wild arabica coffee and other factors, such as pests, diseases, changes in flowering time, and a reduction in bird populations that serve as pollinators.

Field studies in modeling tests were performed at the Boma Plateau, Sudan, in April 2012. Based on the test results, the factors include deforestation, wild arabica could be extinct by 2020. It makes sense to lower the quality of health of wild arabica now. 

Aaron Davis, Head of Research at the Royal Botanic Garden Coffee, Physorg quoted as saying on Wednesday, said, "The purpose of this study is not to make people afraid. Prediction is certainly cause for concern, but we should be able to make it as a basis for the necessary steps."
