CARRASCO CHOQUE, Freddy. Effects of climate change in production and performance in quinua Juli district, period 1997 - 2014. Comuni@cción [online]. 2016, vol.7, n.2, pp.38-47. ISSN 2219-7168.

By the method of agricultural production function, is economically estimates the effects of climate change in the production and performance of quinoa, it is concluded that climatic variables if they affect the production and performance of quinoa, these account for more than 60% and 35% respectively . The climate factor influencing the production and performance is the maximum temperature at a significance level of 10%. The optimum temperatures are 15.2 ° C maximum temperature, minimum temperature -5 ° C and rainfall of 765.5 mm. The behavior of climatic factors shows an increasing trend, and the effect toward production and performance are negative, because as the temperature rises exceeding the optimal threshold required for the cultivation, production and performance of quinoa is reduced. According to the forecast of quinoa production for the next 16 years, the effects will be detrimental not only for quinoa, but for the entire agricultural sector, with risks from declining production and food quality, lower incomes and rising prices. It is important, the implementation of adaptation and mitigation measures for the agricultural sector.

Palabras clave : Climate Change; Production function; optimal threshold temperature; quinoa production; climatic variables.
