How Climate Change Threatens Kenyan Coffee and Tea Crops

Kenyan coffee and tea farmers are grappling with the harsh realities of a warming planet—where once-reliable growing regions are becoming hostile, and diseases are climbing to new elevations. For a global specialty coffee market that prizes Kenya’s bright, complex beans, these shifts aren’t just local news; they’re a warning for the future of origin flavors.

By 2050, some of Kenya’s key tea and coffee farming areas may become unviable due to permanent climate changes, forcing growers to abandon traditional plots or risk failed crops.

The Shifting Geography of Coffee and Tea

Scientists warn that Kenya’s climate trends—hotter, drier spells in the central highlands and increased rainfall in the west—are reshaping where coffee and tea can thrive. Central regions, historically ideal for coffee, are growing drier and less suitable, while western areas, now wetter, could support more coffee. But moving farms isn’t simple: shifting elevations bring new disease risks. Coffee leaf rust, once confined to low altitudes, has moved to mid-elevations, while coffee berry disease is spreading to lower areas.

Tea’s Uphill Battle—and the Forest Barrier

Tea farmers, too, are being pushed to higher ground to escape heat and dryness. Yet many of those higher-altitude zones are protected forest reserves, effectively blocking further expansion. This geographical squeeze threatens the long-term viability of tea production in its traditional heartlands.

Frost, Drought, and the New Pest Threat

Farmers are already seeing the impacts: frost—caused by sharp nighttime drops after warm days—is damaging crops, and combined with dry weather, it’s cut tea yields by 20%. The Tea Traders’ Partnership (ETP) warns that climate change will also introduce new pests and crop disasters. In response, ETP is collaborating with the Tea Research Foundation to develop drought-resistant, pest-hardy clonal tea varieties.

Frequently Asked Questions

Which Kenyan coffee-growing regions are most affected by climate change?

Central highland areas, traditionally ideal for coffee due to cooler temperatures and high altitudes, are becoming drier and less suitable, while western regions are getting wetter and potentially more viable for coffee farming.

What diseases are moving to new altitudes because of climate change?

Coffee leaf rust, once a low-elevation disease, has shifted to mid-elevations, and coffee berry disease is spreading to lower-altitude areas as the climate warms and farming zones move.

Why can’t tea farmers just move higher up the mountains?

Many higher-altitude areas suitable for tea are designated forest reserves, which limits or prevents expansion and puts long-term tea production in those zones at risk.

How much has tea yield been reduced due to frost and dry weather?

Tea yields have dropped by 20% in some areas due to a combination of frost and dry conditions caused by shifting climate patterns.

What is the Tea Traders’ Partnership doing to address climate challenges?

The ETP is working with the Tea Research Foundation to breed clonal tea varieties that are resistant to drought and pests, aiming to adapt to future climate conditions.
