Abstract : Crop losses caused by pests and diseases threaten the food security and income of thousands of families worldwide. In Latin America and the Caribbean, coffee losses have caused severe crises since 2012. Most of coffee farmers manage diverse types of coffee agroforestry systems (CAF); therefore, it is important to know: what shade canopy and management characteristics are able to reduce coffee losses due to pests and diseases, but also provide other ecosystem services such as provisioning, maintenance of soil fertility and carbon sequestration? We worked with two-year data of 61 coffee plots in Costa Rica: firstly, we estimated primary yield losses and secondary yield losses; secondly, we assessed the relationships (trade-offs) between yield losses and indicators of the other ecosystem services; finally, we identified the CAF which had the lowest losses and provided high levels of agroforestry products, soil fertility and carbon sequestration. We identified six CAF as the most promising ones for reducing losses while providing other ecosystem services. One of these systems was a simple CAF; three were medium diversified CAF; and two were highly diversified and dense CAF. For each of these CAF, we described the structure and compo-sition of their shade canopies, management and costs, and the levels of ecosystem services they provide (see Figure). The six CAF represent different options to offer for the design of new CAF or re-design of old and/or unproductive CAF.
