per 100 ppm elevation in CO2 but declines of 4.6% per degree Celsius and 2% per 10% decrease in rainfall . Jennings et al.  projected an overall increase in global potato production, but only if widespread adoption of adaptation measures is achieved. Although increases in CO2 could produce positive yield responses, the effects of temperature may offset these potential benefits . Warming offers the potential of longer growing seasons but can also have negative impacts through disrupted phenology and interactions with pests .
