Tree species diversity and vegetation structure in shade coffee farms in Veracruz, MexicoBackgroundWhile some studies have argued that shade coffee enables similar biodiversity to remnant forest fragments, others contest that the ecological functions of shade coffee can be assumed to be the same or that policies promoting shade coffee will also benefit remnant forest fragments. Not all taxa have been thoroughly studied in shade coffee. This study reports on tree species diversity and vegetation structure in shade coffee farms in Veracruz, Mexico.

Tree biodiversity in farmer cooperatives of a shade coffee landscape in western El SalvadorbackgroundConservation of tropical biodiversity in agricultural landscapes has become more important as the area covered by natural ecosystems decreases. Understanding the types of biodiversity common in agriculturally managed lands, and involving farmers in conservation planning, is important for regional conservation goals.

Coffee Agroforestry Systems in Central America: I. A Review of Quantitative Information on Physiological and Ecological ProcessesBackgroundCoffee (Coffea arabica, L.) is the most widely grown cash crop in Central America. While previous research identified various environmental factors that affect its growth and yield, the authors believe that quantitative knowledge of coffee and other tropical agroforestry systems is still limited. This article provides both a literature review and a summary of quantitative data necessary to develop process-based models for coffee agroforestry systems in Central America.

Coffee Agroforestry Systems in Central America: II. Development of a Simple Process-Based Model and Preliminary ResultsBackgroundGlobally, coffee (Coffea arabica, L.) is an important cash crop. In past decades, there was a growing trend in Central America towards high-input monocultures, but most recently, agroforestry is again becoming a common system. However, it is difficult to optimise the selection of shade tree species in an agroforestry system. This article provides information on a simple dynamic model for coffee-agroforestry systems in Central America. Available with subscription or purchase |

Biodiversity Conservation in Traditional Coffee Systems of MexicoBackgroundThis article discusses the capacity of traditional coffee agroforestry systems for maintaining biodiversity levels. Research Goals & MethodsThe authors describe five coffee plantation systems based on differing vegetational and structural complexity: (1) traditional rustic, (2) traditional polyculture, (3) commercial polyculture, (4) shaded monoculture, and (5) unshaded monoculture.

Shade management in coffee and cacao plantationsBackgroundShade trees reduce the stress of coffee (Coffea spp.) and cacao (Theobroma cacao) by ameliorating adverse climatic conditions and nutritional imbalances and increase the biodiversity of coffee farms, but they may also compete for growth resources. This review summarizes the literature on ecological aspects of shade-grown coffee and cacao and on management of shade trees, but does not address economic and social aspects of shade-grown coffee and cacao.

ITTO Guidelines for the Restoration, Management, and Rehabilitation of Degraded and Secondary Tropical ForestsbackgroundThis guide provides detailed information on the tools and concepts for rehabilitating and managing degraded forests and secondary forests. These lands have an often unrecognized ability and potential for providing valuable ecosystem services and provisioning timber, NTFPs, and other goods. Open access copy available |
Multifunctional Shade-Tree Management in Tropical Agroforestry Landscapes – A ReviewbackgroundThis article discusses the benefits of shade systems in the production of cacao and coffee crops, with a particular focus on the long-term cycle of cacao production. Open access copy available |
Performance of an Improved Fallow System in the Peruvian Amazon—Modelling ApproachbackgroundThis research compares the ecological and economic potential of an improved leguminous tree fallow (using Inga edulis) to the traditional grass fallow (dominated by Imperata brasiliensis) in central Peru.
