The development of terroir(as used in winegrape producing regions) derived bio-climatic indicators linked
withtraditional agriculture knowledgein long-standing tea farmer communities, is very important in developingprecision
agriculture systemfor adapting to climate change. Indicators such as Heliothermal Index, THSW Index, Cool Night Index,
Dryness Index, as well as Soil Respiration Index can be retranslated into indicators for evaluating optimal conditions for growing
quality teas. Selection of the most appropriate land, cultivars and cultivation methods for quality tea production can be applied
and conducted as these indicators are likely to become a powerful tool for monitoring the impacts of climate change and adapting
pro-actively to the environmental transformation, while maintaining and enhancing the values of the teas produced.The
development of bio-climatic indicators will not only be useful for Uji area, but also in other tea growing regions in the world
