Abstract

Climate change is impacting on the agricultural sector in several ways, and the effects on yields are generally among the most observable ones. Open fields crops, such as cereals, are very vulnerable to climate change. We study the historical data on yields of main cereals, namely barley, maize, oats, rice, rye, wheat, to conclude on the long run impacts of temperature and precipitation, over the period 1920-2015. Yields are found to be inversely correlated with temperatures and positively with precipitation, in both cases the relationships are non-linear, as expected.
