Tasks

The person recruited will be responsible for developing a generic module for modelling livestock farming systems, which will be integrated into the MAELIA platform.

This module must be designed to show the structure, operation and diversity of livestock production systems. It will aim to cover a wide range of livestock production systems, from intensive indoor farming systems to extensive, mobile systems on rangelands.

Whatever the context, livestock farming can play an important role in the circularity of agri-food systems through its ability to

i) use uncultivated land, co-products and other residues for animal feed, and

ii) produce livestock manure with a high fertilising value for soils and crops.

The aim of this module will be to represent the dynamic interactions between livestock farming and

i) the production of resources from crops, grasslands, rangelands and agro-industry, and

ii) the use of livestock manure by returning it directly to the soil (during grazing) or possibly via an intermediate processing stage in biorefineries (composting, methanisation, etc.).

The generic module will be based on 4 generic sub-models (feeding, nutrition, animal performance and manure production) which will be coded in MAELIA on the basis of existing modelling work.

Finally, this livestock farming module will be designed to be integrated into stock-flow models in order to simulate the effect of livestock farming systems on the associated nitrogen and carbon cycles, GHG emissions and carbon storage. This module will complement other modules that are either already in existence or under construction in MAELIA, so as to enable modelling of the functioning, and assessment of the carbon footprint, of crop-livestock agroecosystems or agri-food systems.
