IRACHETA-LARA, Ireyli Zuluamy et al. Modeling of risk in the cow-calf system of the state of Chihuahua with socio-economic and environmental indicators. Rev. mex. de cienc. pecuarias [online]. 2017, vol.8, n.2, pp.193-200. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v8i2.4443.

Overgrazing, changes in land use and inadequate management that supports it exposes the cattle-beef systems to an imminent vulnerability. The aim of this research was to develop an integrated model of environmental and socioeconomic indicators of three ecoregions, identifying vulnerability factors and patterns of cow-calf system in the grasslands of the State of Chihuahua that affects the livestock density (LD). The estimation showed that the increasing of LD in the Ejido lands raises the production costs 0.0358 units, by demanding a higher materials and forage intake. The difference in animal units between farm types (considering a technical program of training livestock) decreases depending the areas, and shows that the Ejidos lands are less vulnerable in time of drought. This report will generate useful information for analyzing the potential economic, social and environmental risks in the ecoregions of the state of Chihuahua.
