LUCIA modules

The soil water, organic matter and plant modules are built on concepts of established models, namely KINEROS (Woolhiser et al 1990) and SPAW (Saxton and Rawls 2006), CENTURY (Parton et al 1987) and the Crop Growth Monitoring System CGMS (Supit 2003), which is based on the World Food Studies (WOFOST) model.

Model coupling with LUCIA

The livestock simulator LIVSIM is now a built-in module of LUCIA. LUCIA-LIVSIM has also been soft-coupled to the multi-agent model MPMAS (see Table 1).

Table 1: Coupled models in MLL (MPMAS-LUCIA-LIVSIM), from Marohn et al. (2022)
Model MPMAS - Mathematical Programming-based Multi Agent Systems LUCIA - Land use change impact assessment tool LIVSIM - Livestock Simulator
Domain Agents Soil, plants, landscape Animal herds
Processes Production decisions Plant growth and competition, nutrient cycling, hydrology, erosion Feed-manure conversion, meat /milk production, reproduction
Applications Adoption of innovations Resource base sustainability, environmental impacts of land use Herd performance
Space Explicit Distributed Non-spatial
Timestep Monthly Daily Monthly
Language C++ Python Python
