La restauración de bosques andinos tropicales: Avances, desafíos y perspectivas del futuro

Español

Antecedentes

La degradación ambiental y la pérdida de biodiversidad ponen en riesgo los medios de vida de habitantes de países andinos  tropicales. Respondiendo a esta amenaza, Colombia, Ecuador, Perú y Bolivia han definido metas cuantitativas de restauración ecológica y consecuentemente formulado programas para alcanzar estas metas. No obstante, esto ha presentado retos de distintas magnitudes variando de país en país.

Insectos vs suelo: la importancia de elegir indicadores para el monitoreo de la restauración ecológica.

 

Español

Antecedentes

Amenazados por la degradación de suelos y la sobreexplotación de recursos naturales, los bosques andinos han sido objetos de mutiples proyectos e iniciativas de restauración forestal. Para ser exitosos, los proyectos de restauración deben incluir un plan de monitoreo comprensivo que evalúe indicadores relevantes y sensibles a cambios en el ecosistema. La selección de estos indicadores de monitoreo debe ser juiciosa y hecha en función a los objetivos de la restauración.

Growth of native tree species planted in montane reforestation projects in the Colombian and Ecuadorian Andes differs among site and species

BACKGROUND

Tropical Andes in Columbia and Ecuador have been affected by forest clearance and degradation for several centuries. Agriculture has been the primary driver of land use change as well as mining to a lesser extent. To restore the degraded sites, native species have been used in various projects, however with little information on growth performance of the planted tree species in relation to site and soil nutrient status. A greater part of the northern Andes has volcanic ash derived soils.

Pest management through tropical tree conservation

Background

Deforestation and crop monocultures in Veracruz, Mexico are leading to the disappearance of indigenous trees and the animal species that depend on them. This is particularly troubling to local agricultural workers who benefit from species like hymenopteran parasitoids that attack pest fruit flies. This research evaluates the relationship between hymenopteran parasitoids, pest fruit flies and their fruit hosts and proposes potential strategies for conservation and pest management.

Safety Nets, Gap Filling and Forests: A Global-Comparative Perspective

BACKGROUND

This paper seeks to prove how forests and wildlands are utilized in developing countries as safety nets to shocks, and how they provide resources for seasonal gap filling. The study was carried out in various developing countries in different continents. Areas where there is no forest at all were excluded and those completely forest covered such as those dominated by hunter- gatherers were not considered.

Leaf litter arthropod responses to tropical forest restoration

Background

Soil and litter arthropods play critical roles in tropical ecosystem function including driving organic matter decomposition and nitrogen mineralization. With the increasing need for forest restoration projects, it is important to know how these arthropod communities respond to a variety of restoration strategies and techniques in order to maintain healthy ecosystem function. This study was conducted in a mixed-use agricultural landscape in southern Costa Rica, in an effort to contribute to local restoration research efforts.

Ecosystem-based adaptation for smallholder farmers: Definitions, opportunities and constraints

background

Ecosystem-based Adaptation (EbA) or the use of biodiversity and ecosystem services has been gaining recognition as being a vital part of the overall strategy to help people adapt to the adverse effects of climate change. This study recognizes the importance of EbA in helping smallholder farmers adapt to climate change while providing co-benefits such as livelihood, continued provision of a variety of ecosystem services, and conservation of existing resources.

Participatory research for restoration and agro-ecological production

Background

This chapter describes the process and outcomes of a 25-year participatory research project that was carried out in partnership between CIPAV and farmers of a local community in El Dovio, Valle del Cauca, Colombia. The project was guided by integrated land management and the need to combine biodiversity conservation, ecological restoration, and sustainable use of natural resources.
