The Impacts of Climate Change on Tea Production: a Review
Climate change has been an inconvenient truth attracting much attention from the public, decision makers and scientists.IPCC (2013) reported that almost the entire globe has experienced surface warming.The global surface temperature data show a warming of 0.85 ℃, especially in the Northern Hemisphere, 1983-2012 was likely the warmest 30-year period of the last 1400 years.CO2 concentrations have increased by 40% since pre-industrial times.In the future, continued emissions of greenhouse gases will cause further warming with a likely range of 0.4 to 2.4 ℃ during 2046-2065 (relative to the reference period of 1986-2005).The frequencies of heat waves and heavy precipitation events are very likely to raise with a more uneven regional distribution.IPCC (2013) also believed that crop productivity is projected to increase slightly at mid-to high latitudes for local mean temperature increases of up to 1-3℃ depending on the crop, and then decrease beyond that in some regions.At lower latitudes, especially seasonally dry and tropical regions, it is projected to decrease for even small local temperature increases (1-2 ℃), which would increase the risk of hunger.Interestingly,the impacts of climate change on tea production have never been mentioned in any IPCC assessment report, and few existing studies focus on this issue.Tea production, however,has close relationship with climate and its change.Thus, making a literature review of the impacts of climate change on tea production and adaptation measures, and proposing some future research needs become very necessary.
