EFFECTS OF CLIMATE CHANGE ON THE PRODUCTION AND YIELD OF TWO AGRICULTURAL CROPS IN PIURA, PERU 1973-2018

Abstract

Global warming has altered climate change; For this reason, the behavior of the minimum temperature, maximum temperature, rainfall and their impact on lemon and hard yellow corn crops was investigated. To carry out the research, the Production Function was used as a methodology and as part of the results, the first partial derivative was calculated to find the optimal threshold and the second derivative to find its convex or concave behavior. In the case of lemon, it was found that Rainfall and Maximum Temperature had a negative impact on the production and yield of lemon, all this happened in the short term since in the long term it was the opposite. In the case of hard yellow corn, when the minimum temperature exceeds the threshold, production and yield decrease, on the other hand, when rainfall exceeds the threshold, it increases.

Keywords: climate change, agricultural production function, optimal thresholds, climatic variables.
