WaNuLCAS was developed (using Stella) 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 tree and crop, elementary tree and crop physiology and soil science (daily water, N, P and SOM balance for 4 soil layers and 4 horizontal zones). The model can provide a coherent way of evaluating sustainability indicators, C stocks and profitability for a range of land use systems, considered as 'alternatives to slash and burn'. A new module describes the effects of slash-and-burn land clearing on soil C, N and P transformations.
