Popis: There is increasing evidence that climate change will strongly affect tea cultivation. It will be one of the challenging issues, particularly for the tea plantations of Assam, India. Based on a questionnaire survey carried out in four major tea-growing regions of Assam, viz., Upper Assam, South Bank, North Bank and Cachar, the study analyses tea growers' awareness of climate change, its impact on tea, adaptive approaches undertaken and future strategies. Majority of respondents were aware of climate change and its effect on tea production. Tea growers attributed prolong drought, excessive precipitation within a short period, temperature extremes, increase in insect and disease infestation, the emergence of new insect pest species, increased weed infestation and wind velocity as underlying effects of climate change. Results also specified that tea growers had a positive approach towards adaptive management strategies to mitigate climate change. Adaptive measures executed to combat climate change included rainwater harvesting, irrigation, afforestation, biodiversity conservation, soil mulching and creation of wind barriers. As future management strategies, tea growers have opted to gradually replace synthetic fertilisers with organic manures and pesticides, construct anti-erosion measures along riversides and embankments, generate awareness programs among the workers and other residents on conserving biodiversity, generate clean energy for tea production and cultivate climate tolerant/resistant cultivars. The present study will be helpful to make more informed future strategies regarding best practices for tea cultivation under a changing climate for tea-growing regions all over the world.
