There's been a severe drought in Brazil that's driven up the price of coffee. Isa Soares has the story.
It's strong enough to give you a jolt and keep you wired for the rest [of] the morning,
but at this coffee exhibition in London, little do these customers know there may be a storm brewing in their coffee cup.
According to the Intergovernmental Panel on Climate Change, or the IPCC,
pests, rising heat, extreme temperatures resulting from climate change may impact the supply of coffee, and the industry, it seems, is worried.
I am very concerned. I would say climate change is the most serious threat to the sustainability of the coffee supply chain right now.
The IPCC says that a temperature rise of 2 to 2.5 centigrades [centigrade]
means some coffee-growing countries could run out of cool mountainsides on which to grow their coffee by 2050.
It also predicts that by 2020, coffee production could decline by 34 percent with profits shrinking from $200 per acre to less than $20.
In Brazil, for example, the biggest producer of coffee in Arabica coffee,
a rise in temperature would cut the area suitable for coffee-growing by two thirds,
and that basically means that Brazil would need to look beyond their principal growing areas of Minas Gerais and San Paulo [Sao Paulo] for their coffee.
More importantly, it will impact millions of livelihoods.
We're talking about at least 25 million farmers.
And this means if you think about their families, it's probably 100 million people.
It's a vast, vast number of people who depend directly on coffee as the number-one source of cash.
Though whilst this may prove challenging and devastating for many coffee-growing countries, it can also be an opportunity for others.
Vietnam, for example, has become a much, much bigger player and is now the second largest exporter of coffee or producer of coffee worldwide now after Brazil.
India is now developing its own coffee industry, and as is China.
A dramatic change of landscape for an industry that for years has depended on Brazil, among others, for their economic coffee fix.
