Crop Livestock Enterprise Model released
The Crop Livestock Enterprise Model (CLEM) has recently been released under the aegis of the APSIM Initiative. CLEM is a biophysical model that enables researchers in developed and emerging-economy countries to examine the effects at the farm scale of different management practices, and to assess the risk and variability of practices over the medium (10+ year) term.
CLEM can be used to examine trade-offs between crops, livestock, labour and economic components of the farm business. CLEM can account for and output multiple variables including crops, animals, economics, residue, products, labour, nutrition, feed, water and greenhouse gases. It has built-in user-friendly graphics.
CLEM has the potential to:
- Examine farming system production risk and variability under different allocations of labour, crop and livestock resources
- Show the overall benefits or costs of management changes such as: increased rumen efficiency; fly strike vaccines and chemical solutions; pest and disease control options
- Consider the effect of new digital technologies such as virtual fencing or measuring feed
- Inform policy makers and industry bodies about the likely effects of changes to farm-scale management at a district or regional level
CLEM has been developed out of the Northern Australian Beef Systems Analyser (NABSA) and the Integrated Assessment Tool (IAT) models. It uses a tree structure similar to APSIM and is user-friendly and easy to navigate.
