Sustainability indicators for Brazilian dairy livestock: the perception of professionals in the sector

Abstract

The objective of this study was to analyze the perceptions of professionals in relation to the importance of indicators used to assess the sustainability of Brazilian dairy cattle. A survey method was used through a questionnaire. The target audience was professionals related to dairy cattle: researchers, professors, consultants, farmers, and other professionals. The total number of respondents to the survey was 347. Cluster analysis resulted in the formation of four distinct groups: G1 ("Holistic"), participants agreed that all indicators are very important or, at least, important; G2 ("Technician") considered the indicators important and desirable, except for some environmental indicators which were assessed as non-priority and expendable; G3 ("Socioenvironmentalist") assessed the indicators as desirable, but environmental indicators received more importance; and G4 ("Skeptic") generally believed that indicators were non-priority and expendable. The groups showed significant differences in relation to knowledge about technical, economic, social, and environmental aspects of dairy cattle. More than 60% of professionals consider milk production per area, reproductive index, production costs, profit from the activity, milk quality, quality of life of the producer and employees, succession, protection of water courses, and soil management as very important indicators of the sustainability of dairy cattle. On the other hand, important environmental indicators such as emissions of gases and substances, energy use, nutrient balance, and land use were neglected by most respondents. These results can help select and implement policies and strategies for decision making, aiming at producing milk in a more sustainable way.
