The sector most economically affected by climate change is expected to be agriculture, being affected by the decline in economic income. The objective of the research was to know the impact of climate change on agriculture in Irrigation District 005, located in the state of Chihuahua, through the application of surveys in 2020. Chi-square tests were performed, of the respondents, 40% [X2(138.32) p< 0.001] has more than 20 ha, 65% grows mainly pecan tree (Carya illinoinensis), 97.89% [X2(187.17) p< 0.001] has heard of climate change and 44.09% [X2(155.33) p< 0.001] defines it as pronounced climatic variation between seasons. The multiple correspondence analysis estimated that the variables that presented greater inertia for the first dimension were: zero tillage (M1), change of type of crop (M3), water collection techniques (M4), others (M5) and percentage of contribution (cmedidas), for the second dimension, those that presented greater inertia were: those who have suffered economic losses (peconomicas), most affected period (periodo), cause of the impact (causa), percentage of economic losses (pp). Two multinomial logistic regression models were run, the measures applied to reduce the effects of climate change were zero tillage and the use of organic products. The results obtained showed that as the age of the producers increases, the possibility that they know about climate change, its causes and choose to take out insurance decreases. Finally, more than one mitigation/adaptation measure needs to be applied to counteract climate change.
