    Abstract


    Chuong My is a suburban district of Hanoi with a rapid development of pig farming, accompanied by the problem of environmental pollution. For the sustainable development of livestock production, besides improving production efficiency, it is necessary to reduce environmental pollution. This study measured production efficiency considering environmental factors (environmental efficiency) to assess the sustainability of pig farms in the district. This study used the data envelopment analysis (DEA) model with undesirable output (COD emissions) to measure environmental efficiency in pig production. The research results showed that the average production inefficiency score was 1.07, while the average environmental inefficiency score was 1.19. This shows that if environmental factors are not considered, the measurements of production efficiency are biased. Using Tobit regression, the study showed that the factors that increased environmental efficiency were the installation of biogas digesters and the pollutant removal efficiency of manure treatment facilities. Meanwhile, increases in the volume of wastewater discharging into the treatment plants reduced environmental efficiency. These findings confirm the importance of biogas plants in manure treatment in Vietnam. To improve environmental efficiency, it is necessary to enhance the efficiency of treatment facilities and apply water-saving technologies in livestock production.
