Comparative carbon footprints of buffalo milk produced at smallholder and organised farms in Hisar district of Haryana, India

Abstract

The present study was conducted to compare the carbon footprint of milk produced in 75 smallholder farms and two organised buffalo farms in Hisar district of Haryana using Life Cycle Assessment approach. Primary data was collected from farmers and farm managers for the study. Functional unit was one litre of milk with system boundary being ‘Cradle-to-farm gate’. Methodology prescribed by Intergovernmental Panel on Climate Change was used for estimation of emissions from different sources. Secondary data was also relied upon for synthetic fertilizers and seeds, combustion of fossil fuel, production of concentrates and dry fodders. The average carbon footprint of milk produced in rural smallholder and organised farms were 3.54 and 4.53 kg CO₂-eq./L milk, respectively, indicating superiority of village level production systems. Methane from enteric fermentation was estimated to be contributing nearly half of the total greenhouse gas emissions. It is suggested that rural smallholder production systems should be favoured over organised ones given the lower greenhouse gas emissions.
