Matcha, a long-time popular drink in Japan, has gone global. Major chains now serve it, and coffee start-ups are competing to offer their own photogenic takes on the vivid green drink.

But the growing craze exposes bigger problems for the wider tea industry.

Tea is a delicate crop, highly sensitive to changing weather conditions. Around the world, farmers are reporting falling yields, altered growing seasons and a higher risk of disease due to climate change. Labour shortages and economic issues are also affecting supply chains, creating uncertainty for producers and consumers.

From drone technology helping to monitor remote fields to the extraordinary claim that tea could one day grow on the moon, scientists and growers are exploring bold new solutions.

Is trouble brewing for the worldwide tea industry?
