Climate change has harmed not only environment and animals but also human's life. As people know, Brazil is the largest coffee producer in the world. Many other countries import Brazil's good quality product and enjoyed. However, rise in global temperature has a negative impact on coffee farms.
Coffee rust called la roya, disease has spread widely across Central America and infected coffee plantation. Warm weather helps fungus (la roya) thrive, which attacks the leaves of coffee bush. In particular, the Arabica beans that occupy about 70% of coffee produce in Brazil has been affected by even 1degree rise on temperature because their proper temperature is between 18c and 22c.
Many people living in Central America has income from their small coffee farms in rural areas and depends on it. The loss in coffee production due to fungus outbreak leads to hiring less coffee picker, paying not enough wages, raising coffee price.
When is the first appearance of Coffee rust? The advent of la roya was in 1970 , which caused by the climate change. Usually coffee farms located in higher altitude above from 800meteres to 1200meters but the fungus was able to reach coffee leaves in this area because weather helped them.
Fortunately, there is good news! There are roya-resistance trees planted in Colombia. These trees named Castillo roya-resistant tree will be prepared to distribute their seedlings to famers across the South America. Furthermore, there are emergency programs that agronomist visit the coffee farms and help them against roya.

I think we have to improve the title of this article because technically speaking, in agricultural plant pathology, coffee rusts are caused by fungi and not climate change. However, this article is very timely because it clearly demonstrates how climate change can accelerate the growth of these pathogens, spread the disease faster, and eventually impact the production.

Everything and every being is affected by the climate change and coffee can remain no exception. But is good news that Castillo roya-resistant tree will be used for distribution of seedlings across South America.
Thank you for informative report dear Luiz :)

Rahul, coffee is also one of my favourite drinks. Moreover, Brazil's coffee production is very significant in the world economy and consumption. =)

Harmanjot, you are right. The roya resistance is great news!! Thanks for the comment mate. =)

Coffe is my favourite drink.
Coffee rust is serious issue so are the other plant diseases which has become a challenge for the agriculturalist. Plant disease is one of the major cause of lower yield. Thanks to global warming and Climate change, the condition have become optimum for such disease pest to brooding and attacking.
But we have some resistant varieties of different crops at the brighter side. Like one we had for coffe :D ^_^
Thanks for the report Luiz :)

Climate change and global warming indeed have far reaching effects and impacts.Even coffee plantations are indirectly affected as said in the report thus affecting those people whose livlihood depends on coffee plantations.But roya resistance plants are a good news.Thanks for sharing!

Rising temperatures resulting from climate change are fuelling the growth of rust, ravaging the coffee plantations . It's unfortunate that this impacts the lives of all those who thrive on coffee production for their living. Glad to know about roya-resistance trees and emergency programs being worked. Thanks for another informative report , Luiz.
