Esta investigación analizó la relación entre variables productivas y la huella hídrica en la producción primaria de leche en fincas a pequeña escala en la zona central del departamento de Boyacá. Se llevó a cabo un estudio cuantitativo y correlacional en 50 sistemas ganaderos cuyo principal objetivo es la producción de leche. Se calcularon los parámetros: porcentaje de hembras en ordeño, producción por área y por hembra, y carga animal. Se estimó la huella hídrica dividida en tres categorías: azul, verde y gris. Los datos fueron procesados por RStudio, se realizó el test de Shapiro-Wilk, el coeficiente de correlación de Spearman y análisis de regresión lineal múltiple. En los resultados se identificaron la Huella Hídrica Total (x&#772; 1,01 m3/L), Huella Azul (x&#772; 0,01 m3/L), Huella Verde (x&#772; 0,19 m3/L) y Huella Gris (x&#772; 0,81m3/L). Las variables Porcentaje de hembras, Productividad Kg/Hembra/año y Productividad Kg/Ha/año muestran los más altos coeficientes de correlación, siendo más fuertes con la Huella Azul. Se evidencia potencial para mejorar la sostenibilidad ambiental de la producción lechera mediante la adopción de prácticas eficientes, especialmente en el componente animal.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In recent decades, water use in livestock production has emerged as a significant topic within the discourse on sustainable food systems and competition for water resources. This research examines the relationship between productive variables and the water footprint in primary milk production on small-scale farms in the central zone of the department of Boyacá. A quantitative and correlational study was conducted involving 50 livestock systems primarily focused on milk production. The following parameters were assessed: the percentage of milking females, production per area, production per female, and stocking rate. The water footprint was estimated and categorized into three distinct types: blue, green, and gray. Data analysis was performed using RStudio, incorporating the Shapiro-Wilk test, Spearman's correlation coefficient, and multiple linear regression analysis. The results revealed a Total Water Footprint of (x&#772; 1.01 m3/L), a Blue Footprint of (x&#772; 0.01 m3/L), a Green Footprint of (x&#772; 0.19 m3/L), and a Gray Footprint of (x&#772; 0.81 m3/L). The variables Percentage of Females, Productivity Kg/Female/Year, and Productivity Kg/Ha/Year exhibited the highest correlation coefficients, with the strongest correlation observed with the Blue Footprint. The findings suggest potential avenues for enhancing the environmental sustainability of dairy production through the implementation of efficient practices, particularly in relation to the animal component.]]></p></abstract>
