WaNuLCAS was developed to represent tree-soil-crop interactions in a wide range of agroforestry systems where trees and crops overlap in space and/or time (simultaneous and sequential agroforestry).

The model is based on above and below ground architecture of trees and crops, elementary tree and crop physiology and soil science. It can be used for exploring positive and negative interactions for different combinations of trees, crops, soil, climate and management by the farmer.

WaNuLCAS makes use of the STELLA modelling environment and thus allows users to modify parameters between simulations and add model structure and relations of specific interest. It can be used for teaching as well as research.
