Tea drinkers may soon face a harsher, more inconsistent cup as climate change disrupts the environmental conditions vital for maintaining tea quality. Christian Aid’s recent report highlights how rising temperatures and erratic rainfall in key tea-producing countries like Kenya, India, and Sri Lanka are undermining the delicate balance of flavor that customers expect.
The report details how fluctuating weather patterns, including droughts and floods, already impact tea harvests by reducing leaf size and altering taste. Small-scale farmers such as Reuben Korir from Kenya describe unpredictable rainy seasons and extended dry spells that affect crop quality and revenue. Such volatility creates challenges not only for growers but also for the global tea supply chain, leading to price spikes and inconsistent availability for consumers and brands striving for flavor uniformity.
Experts add that as climate variability intensifies, achieving the familiar taste profile that tea brands promise will become increasingly difficult. Dr Neha Mittal, a climate scientist, explains that stable temperature and rainfall are essential to maintaining the consistent flavor that consumers recognize and value.
The report also underscores the instability in tea markets tied to climate shocks. These disruptions can cause unexpected fluctuations in tea output and pricing, which affect both farmers’ livelihoods and consumer costs. For instance, Sri Lanka faced a significant decline in tea production following a fertilizer import ban, which exacerbated the negative effects on harvests beyond climate factors.
Christian Aid’s recommendations to counter these impacts include reducing carbon emissions globally, expanding climate finance from wealthier to poorer nations, and promoting organic tea production as a sustainable alternative. The emphasis remains on mitigating climate change to preserve the economic and sensory value of tea worldwide.
