Quelques réussites dans la réduction de la déforestation: Des pays tropicaux où les politiques de protection de la forêt et de reboisement ont fonctionné

This report highlights successes of developing countries and their strategies for reducing deforestation and as a result, their emissions of greenhouse gases. The authors note that decreases in deforestation are primarily a result of REDD+ programs, including payments for ecosystem services, better law enforcement, governance reforms, moratoria on deforestation practices, and incorporating the environment in development efforts. Other successes come from policy changes and programs that have had intended and unintended positive impacts on forests.

Ouragans et diversite biologique dans les forets tropicales. L’exemple de la Guadeloupe (Hurricanes and diversity in tropical forests: the example of Guadeloupe).

The authors examined the relationship between hurricane disturbances and biodiversity and found that diversity of forests increased their resistance to hurricane disturbances. They concluded that recurrence of strong hurricanes could lead to extirpation of rare or vulnerable non-pioneer species.

Local Knowledge Helps Select Species for Forest Restoration in a Tropical Dry Forest of Central Veracruz, Mexico

background

This paper presents a participative approach to species selection in forest restoration in the tropical dry forest in Mexico. Recent shifts in government programming now favor the planting of native speices over exotic timber species that have historically been used in reforestation projects.

Mapping Species Composition of Forests and Tree Plantations in Northeastern Costa Rica with an Integration of Hyperspectral and Multitemporal Landsat Imagery

background

This article discusses the improvement in accuracy of remote sensing to monitor and evaluate reforestation projects by combining moderate-resolution and hyperspectral imagery with multi temporal, multispectral data. The combination of these technological monitoring methods allows researchers to accurately classify general forest types and tree plantations by species composition.

Actitudes de los productores ganaderos de El Petén, Guatemala, respecto a la implementación de sistemas silvopastoriles (Cattle farmers’ attitudes toward the implementation of silvopastoral systems in El Petén, Guatemala)

 

Español

antecedentes

Hay evidencia que sugiere que los sistemas silvopastoriles son ecológicamente sustentables, económicamente rentables y contribuyen a la mitigación de riesgos a nivel finca. No obstante, productores ganaderos en Centroamérica han tardado en adoptar e implementar estos sistemas. Este estudio presenta la interrogativa y explora las razones por las cuales ganaderos no han adoptado sistemas silvopastoriles de manera más amplia.

Live Fences and Landscape Connectivity in a Neotropical Agricultural Landscape

Background

This article describes the role and importance of live fences in the tropical regions of Central America. The study site covered an area of 4483ha and is located in a wet tropical forest zone in the Province of Heredia, Costa Rica. The landscape is dominated by cattle pasture and possesses a small, fragmented and homogenous structure with small patches of forests.

Designing Pest-Suppressive Multistrata Perennial Crop Systems: Shade-Grown Coffee in Central America

background

This paper analyzes opportunities to realize the benefits of the presence microflora and fauna in coffee plantations by considering species selection, complimentary characteristics, density, and spatial arrangement of tree species . This study addresses reducing the presence of pests and pathogens such as  leaf rust, coffee leaf minor, berry borer, and the American leaf spot. The authors hypothesize that for every soil and climate for coffee, a multistrata system creates a micro-environment that can create a complex ecosystem to resist pests as a whole as opposed to a pest-by-pest strategy.
