The FarmTreeTool is a modelling tool that quantifies the production (fruit, wood, etc.) and services (soil conservation, carbon, etc.) provided by agroforestry systems, at plot, farm or landscape level. It can gauge a wide range of effects of agroforestry at multiple levels, from farm level to landscape level to national level.

The FarmTree® Model generates different types of indicators for up to 50 years

Field-level evidence is translated into cause-effect relations that capture trends and generate agronomic, financial, ecological and social indicators for forecasting future farming scenarios. These scenarios can be tailored and made more precise by adding local data to the global defaults, and thus agroforestry systems’ performance can be estimated.

You appear to have by far the most sophisticated system in place to model the performance of mixed tropical systems in terms of yield and ecosystem services.  Roeland Kindt, World Agroforestry (ICRAF) and Centre for International Forestry Research (CIFOR)
