Abstract:

Farm management decisions can be complex, involving allocation of limited resources to competing tasks, each of which influences the final outcome. This makes it difficult to evaluate the impact of different practices on farm resources, including labour and machinery, fodder, crops, livestock and water, as well as whole farm income and externalities such as greenhouse gas emissions. The Crop Livestock Enterprise Model (CLEM) is a dynamic, bio-economic model developed to simulate the effect of diverse activities on whole of farm resources and at scales ranging from large farm businesses to smallholder subsistence farms. CLEM is a modular simulation tool included within the Agricultural Production Systems sIMulator (APSIM next generation) modelling framework. CLEM highlights the outcomes of practice change by providing simulated information to support better-informed management decisions such as identification of: the profitability of alternative practices, the likelihood of resource shortages, and the changes in labour required from adopting new technologies.
