CANO-VILLEGAS, Omag et al. Trends of climate change at the mid-low Nazas-Aguanaval inland basin based on a geographical approach. Ecosistemas y recur. agropecuarios [online]. 2021, vol.8, n.3, e2704.  Epub Oct 31, 2022. ISSN 2007-901X.  https://doi.org/10.19136/era.a8n3.2704.

An integrated geographical climate change evaluation is presented to identify regional patterns of variability in maximum and minimum temperatures, and precipitation at the mid-low Nazas-Aguanaval basin within the States of Durango and Coahuila in Central Northern Mexico by using decadal mean values from 1961-2020. The historical data were acquired from 26 field meteorological stations. The data were organized by the geographical features of elevation, longitude and latitude, and in three groups each. From the overall analysis, the southern and eastern low elevation sites resulted to be the most vulnerable in facing climatic change. By downscaling the meteorological variation, it was possible to improve the understanding of those mechanisms relying on regional climate variability and climate change at a local level. This evaluation can be further incorporated into the management strategies of different stakeholders in arid and semi-arid lands, particularly within the Chihuahuan Desert.
