The goal of this study was to compare the productivity and ecological sustainability of an integrated crop and animal production system to that of a single crop production system using an emergy analysis technique. This study was carried out in 2019 utilizing data obtained from smallholder agricultural land and livestock systems in Boland village, Sistan area, Iran. The quantity of emergy used to support Boland Sistan village's agricultural and integrated production systems was 4.41E+18 and 9.43E+18 sej/yr, respectively. Specific emergy (SpE), emergy yield ratio (EYR), emergy investment ratio (EIR), environmental loading ratio (ELR), emergy exchange ratio (EER), net profit density (NBD), and output to output ratio (O/I) demonstrated that the integrated system generates a higher net profit than individual crop systems due to positive interactions between agricultural and livestock components as well as high environmental sustainability. Because of its favorable climate and abundant natural resources, the Sistan area can produce a wide range of crops throughout the year, and there are several potential to combine crops and cattle in this region. According to the findings of this study, crop and livestock integration has the potential to reduce economic risk and increase profitability, as well as provide many benefits for the protection of soil and water resources and nutrient cycle productivity. As a result, an integrated crop production system is recommended as a suitable option for producers to diversify agricultural operations in order to avoid hazards, improve crop production, and prevent environmental damage.
