Tata Global Beverages announced on Monday it has commissioned the Tea Research Association (TRA) to identify indicators of climatic changes that will impact tea growing regions in Assam in the next 50 years."The company as part of its association with Ethical Tea Partnership (ETP), has commissioned TRA to identify and capture indicators of climatic changes that will impact India's tea growing regions in the next 50 years," a statement said...The company said the report aimed at identifying those areas that would continue to remain suitable for tea cultivation and those areas that would require adaptation and those that might become unsuitable and hence, might need to switch from tea to other crops... "The predicted probability distribution of tea in the future shows that by 2050, the suitability of these tea growing regions of Assam will reduce drastically, and tea production could shift towards comparatively higher and cooler altitude areas," a release said."Tea growing regions are likely to be severely susceptible by 2050 to changing climate, if adaptation measures for combating the change are not adopted," said company managing director and CEO Ajoy Misra.
