Conceptualizing Forest Degradation

Trends in Ecology & Evolution, 2015
Forest degradation is a global environmental issue, but its definition is problematic. Difficulties include choosing appropriate reference states, timescales, thresholds, and forest values. We dispense with many such ambiguities by interpreting forest degradation through the frame of ecological resilience, and with reference to forest dynamics ...

Restoration of Degraded Tropical Forest Landscapes

Science, 2005
The current scale of deforestation in tropical regions and the large areas of degraded lands now present underscore the urgent need for interventions to restore biodiversity, ecological functioning, and the supply of goods and ecological services previously used by poor rural communities. Traditional timber plantations have supplied some goods but have

Effects of Tropical Forest Degradation on Amazon Forest Phenology

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
Anthropogenic disturbances in tropical forests cause short-and long-term alterations in forest structure, species composition, and successional processes. However, improved understanding of the impacts of disturbance on forest functioning is needed to support forest management and conservation.

Forests to the People: Decentralization and Forest Degradation in the Indian Himalayas

World Development, 2010
Summary This paper assesses degradation of forests managed by local communities (Van Panchayats (VPs)), relative to state protected and open access forests in the Indian state of Uttaranchal. It is based on ground-level ecological measures of forest quality (including canopy cover, biomass, lopping, and regeneration) in forest areas adjoining a ...

The degradation of 2,4-D in forest litter

Bulletin of Environmental Contamination and Toxicology, 1967
These studies have shown that 2,4-D is rapidly degraded in forest litter and that the rate of degradation varies with the type of litter, herbicide formulation and the presence of DDT. The degradation of 2,4-D varies slightly in litter from different vegetation types when incubated under similar environmental conditions.

Sensor capabilities for deforestation and forest degradation

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The FCT Task focuses on demonstrating through coordinated Earth Observations data acquisitions and the development of standardised processing and analytical techniques by researchers in different countries under what are called 'National Demonstrator' programs that remotely sensed products can provide the information needed for national forest ...
