Can Science Contribute to Smallholder Management of Complex Systems? Lessons from Agroecological Intensification of Multi-Strata Coffee with Banana por Staver, Charles, Siles, P., Bustamante, O., Castellon, N., Cerdan, C., Garming, H., Burkhardt, J.

“…Five agroecosystem-based decision tools to intensification resulted – optimisation of light resource partitioning among trees, banana and coffee; macronutrient input-output analysis, including nitrogen contribution of leguminous trees; banana bunch, stem and mat management; landscape, farm and plot management of Fusarium wilt to reduce impact on Gros Michel, the preferred market banana; and strategies for increased banana prices and margins. The process of prototype development bringing together seven grower groups, advanced institute and local banana and coffee scientists and German and Latin American students was analysed to identify lessons for the contribution of science to farm household management of the complex field and farm coffee agroforestry-based agroecosystem. …”
