Facultad de Ciencias Agropecuarias
El 21 de abril de 1982, por resolución del Honorable Consejo Universitario se establece la Facultad de Ciencias Agropecuarias, de la Universidad de Cuenca. La Facultad de Ciencias Agropecuarias es una institución formadora de talento humano en el área agronómica, a través de una educación de calidad, centrada en la investigación y vinculación con la colectividad. Los futuros profesionales médicos veterinarios zootecnistas e ingenieros agrónomos, durante su permanencia en las aulas y estudio de campo, desarrollan conocimientos científicos-tecnológicos, competencias y destrezas en procesos de producción agropecuaria. Se los prepara con el fin de preservar la salud de los animales y recursos naturales, fomentando la seguridad alimentaria, respetando el medio ambiente dentro del marco del Buen Vivir, englobado en las necesidades de la región y el país.

    Drivers of woody dominance across global drylands
    (2024) Castro Quezada, Patricio Salvador
    Increases in the abundance of woody species have been reported to affect the provisioning of ecosystem services in drylands worldwide. However, it is virtually unknown how multiple biotic and abiotic drivers, such as climate, grazing, and fire, interact to determine woody dominance across global drylands. We conducted a standardized field survey in 304 plots across 25 countries to assess how climatic features, soil properties, grazing, and fire affect woody dominance in dryland rangelands. Precipitation, temperature, and grazing were key determinants of tree and shrub dominance. The effects of grazing were determined not solely by grazing pressure but also by the dominant livestock species. Interactions between soil, climate, and grazing and differences in responses to these factors between trees and shrubs were key to understanding changes in woody dominance. Our findings suggest that projected changes in climate and grazing pressure may increase woody dominance in drylands, altering their structure and functioning.
