| Summary: | Indonesia is a prominent example where crossbreeding with European breeds has been promoted to intensify beef production. It is implemented throughout the country regardless of the different agro-ecological conditions, of which the available feed resources are the main element. Crossbreeding at farm level in Central Java showed that crossbreeding has not changed the farming systems or motivations for keeping cattle. These results lead to our hypothesis that we expect no differences in global warming potential (GWP) of local and crossbred cattle production systems in Central Java. Life Cycle Assessment (LCA) is acknowledged method to assess the contribution of livestock production to GWP. Expressed per kg live weight, GWP of local and crossbred cattle was 29.1 kg CO2 and 32.1 kg CO2. These results were higher compared to the GWP of beef cattle production systems in European countries and Japanese. Future LCA’s of smallholder systems should pay more attention to the multi-functional aspects of a production system, because the GWP’s mitigation depending on the multi-functions included.
