Full-text available
While the potential of agroforestry products to contribute to rural livelihoods is well-recognized, the quantification of their yields, incomes, and value for domestic consumption (VDC) and knowledge about their relationships with biodiversity are still scarce. This information is crucial for choosing the best strategy for growing cocoa in tropical...

Full text can be downloaded here: https://authors.elsevier.com/a/1aw2v_5y7z4rS2 Crop losses caused by pests and diseases decrease the incomes and threaten the livelihoods of thousands of families worldwide. A good example of the magnitude of these impacts are the massive crop losses experienced by coffee farmers in Central America due to coffee le...

The cocoa tree (Theobroma cacao L.) is cultivated typically in agroforestry systems in close association with a rich list of tree species and other useful plants on the same plot. Cocoa based agroforestry systems are credited for stocking significant amounts of carbon and hence have the potential to mitigate climate change. Since cocoa yields decre...

The goal of sustainable coffee production requires multiple functions from agroforestry systems. Many are difficult to quantify and data are lacking, hampering the choice of shade tree species and agronomic management. Process-based modelling may help quantify ecosystem services and disservices. We introduce and apply coffee agroforestry model CAF2...
Article
Significance Food production depends on biodiversity and ecosystem services (ES) such as pest control and pollination. Our knowledge about biodiversity benefits to crop production has increased in recent decades, but most studies treat ES separately and then add up their values. Ignoring that these services, being part of the same system, likely in...

A bstract Cocoa farmers must decide on whether to rehabilitate (Rh) or to renovate (Re) a cocoa orchard when its productivity declines due to ageing, disease outbreaks or other causes. Deciding on Rh/Re is often a complex, expensive and conflictive process. In this review, we (1) explore the diversity of contexts, driving forces, stakeholders and r...

The coffee sector in the Dominican Republic is in crisis due to attacks by pests and diseases, high production costs, adverse weather conditions and limitations on the integration of the chain actors. A large part of the coffee growers (70%) have begun to rehabilitate their coffee plantations and / or renew them with varieties resistant to coffee r...

Latent effects of climate variability on coffee development and productivity have generated uncertainty in the coffee sector in Costa Rica. Given this problem, COOCAFE consortium implemented an evaluation and monitoring process for a group of associated farms, located in the provinces of Guanacaste, San José, and Puntarenas. This study applied the...

Article
The outbreak of frosty (Moniliophthora roreri) and black pod (Phytophthora palmivora) in Central American cacao agroforests throughout the 1980s led to the breeding of Theobroma cacao clones resistant to these diseases. However, while clonal disease resistance has been well-documented, clonal adaptability to contrasting pedoclimates remains less un...
Article
Full-text available
Despite many years of research, there is still a lack of consensus as to the nature of the relationship between shade trees and agronomic intensification in coffee agroforestry systems. While some studies find unshaded intensively managed coffee is the most productive, other studies find no trade-off between shade characteristics and productivity....

Using knowledge of leaf functional traits, such as those forming the leaf economics spectrum (LES), to understand plant responses to environmental change is well-established and now being more widely applied to agroecosystems. Yet, little is known about how farm managers invoke leaf functional traits to inform management decisions. The objectives o...

Thesis
Crop losses due to pests and diseases are a major threat to incomes and food security of thousands of rural families worldwide. The assessment of crop losses (yield and economic losses) and their causes is needed to improve the development of agroecosystems capable to offer good crop yields, regulation of pests and diseases, and other ecosystem ser...

Full-text available
The assessment of crop yield losses is needed for the improvement of production systems that contribute to the incomes of rural families and food security worldwide. However, efforts to quantify yield losses and identify their causes are still limited, especially for perennial crops. Our objectives were to quantify primary yield losses (incurred in...

Trees-on-Farms (TonF) are ubiquitous. Farmers obtain numerous goods and services from their trees, which help them to cope with their livelihood needs and contingencies, climate change, and other stresses. Some benefits from trees on farms are extensive to the global society. Decision and policy makers as well as development leaders are not conscio...

Full-text available
Sustainable food production in home gardens should be developed considering the effects of climate change. By focusing not only on long-term productivity, but also on the socioecological sustainability of the production systems, agroecology contributes ideas that foster agricultural systems that are both more environmentally friendly and socially s...

In the humid tropics, the rapid rate of deforestation has resulted in a race to protect remaining forest patches that are increasingly isolated within a rapidly expanding agricultural matrix. In these landscapes, a significant area consists of complex agro-forestry systems with high structural and functional plant diversity, providing critical reso...

Cocoa–timber systems have been proposed as viable alternative for simultaneously satisfying the livelihood needs of the farmers (in terms of production of cocoa and other goods for family use or sale) while improving the capacity of the cocoa agroforestry system to provide other ecosystem services at both the plot and landscape level. In this paper...

We analyzed the relationship of pollinating insects Ceratopogonidae (Atrichopogon, Dasyhelea, Forcipomyia) with shade canopy and land cover characteristics of cocoa agroforestry systems (AFS) for cocoa and cocoa production potential through the action of flowers pollinated naturally by pollinators. Pollinators were found in 60% of cocoa-AFS evaluat...

Project
Our overall goal is to help conserve Neotropical migratory birds by promoting bird-friendly management of coffee farms in the birds’ overwintering range. We aim to demonstrate the economic benefits to coffee farmers of bird-friendly management practices, via two complementary ecosystem services: pest control and pollination. Our research project is designed to build capacity and awareness of these ecosystem services among coffee farmers and those who support them.
Project
To enhance Latin American capacities to develop nature-based solutions and technologies to mitigate climate change.
