An integrated sustainability indicator in specialized dairy index (IISLE) is proposed for the evaluation of these production systems in four dimensions (financial, technical, social, and environmental). This index was validated in a study carried out with information from 18 dairy farms in Antioquia, a Colombian milk production region. The analytic hierarchy process (AHP) method was applied to prioritize criteria and sub-criteria. According to the proposed dimensions, four criteria were established (financial (ISDF), technical (ISDT), social (ISDS), and environmental (ISDA)) and 30 sub-criteria were analyzed. A multiple correlation analysis was performed to determine the intensity of the relationship among these four criteria and the overall index. The methodology includes a cluster analysis for the calculated IISLE. R software was used in the analysis. The proposed indicator is a powerful and useful planning and control tool for the evaluation of sustainability levels in dairy farms and is highly influenced by financial and technical criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
