Trends of climate change at the mid-low Nazas-Aguanaval inland basin based ona geographical approach

Abstract

An integrated geographical climate change evaluation is pre-sented to identify regional patterns of variability in maximum and minimumtemperatures, and precipitation at the mid-low Nazas-Aguanaval basin withinthe States of Durango and Coahuila in Central Northern Mexico by usingdecadal mean values from 1961-2020. The historical data were acquiredfrom 26 field meteorological stations. The data were organized by the geo-graphical features of elevation, longitude and latitude, and in three groupseach. From the overall analysis, the southern and eastern low elevation sitesresulted to be the most vulnerable in facing climatic change. By downscalingthe meteorological variation, it was possible to improve the understandingof those mechanisms relying on regional climate variability and climatechange at a local level. This evaluation can be further incorporated into themanagement strategies of different stakeholders in arid and semi-arid lands,particularly within the Chihuahuan Desert.
