Combining post-disturbance land cover and tree canopy cover from Landsat time series data for mapping deforestation, forest degradation, and recovery across Cambodia

International Journal of Digital Earth, 2022
Mapping of deforestation, forest degradation, and recovery is essential to characterize country-level forest change and formulate mitigation actions. Previous studies have mainly used a simple forest/non-forest classification after forest disturbance to ...

Proximate Causes of Forest Degradation in the Democratic Republic of the Congo Vary in Space and Time

Frontiers in Conservation Science, 2021
Forest degradation, generally defined as a reduction in the delivery of forest ecosystem services, can have long-term impacts on biodiversity, climate, and local livelihoods. The quantification of forest degradation, its dynamics and proximate causes can

The drivers and impacts of Amazon forest degradation [PDF]

Science, 2023
Approximately 2.5 × 10 6 square kilometers of the Amazon forest are currently degraded by fire, edge effects, timber extraction, and/or extreme drought, representing 38% of all remaining forests in the region. Carbon emissions from this degradation total up to 0.2 petagrams of carbon per year (Pg C year −

Detecting Forest Degradation in the Three-North Forest Shelterbelt in China from Multi-Scale Satellite Images

Remote Sensing, 2021
Detecting forest degradation from satellite observation data is of great significance in revealing the process of decreasing forest quality and giving a better understanding of regional or global carbon emissions and their feedbacks with climate changes.

Monitoring intra and inter annual dynamics of forest degradation from charcoal production in Southern Africa with Sentinel – 2 imagery

International Journal of Applied Earth Observations and Geoinformation, 2020
The contribution of forest degradation to changes in forest carbon stocks remains poorly quantified and constitutes a main source of uncertainty in the forest carbon budget.

Monitoring Approach for Tropical Coniferous Forest Degradation Using Remote Sensing and Field Data

Remote Sensing, 2020
Current estimates of CO2 emissions from forest degradation are generally based on insufficient information and are characterized by high uncertainty, while a global definition of ‘forest degradation’ is currently being discussed in the scientific arena ...

Spatial Determinants of Forest Landscape Degradation in the Kilimanjaro World Heritage Site, Tanzania

Central European Journal of Geography and Sustainable Development, 2022
Forest degradation occurs in natural World Heritage Sites (WHS) in the Global South despite the implementation of various strategic policies and the World Heritage Convention (WHC) on forest protections of the sites and this poses challenges to improve

Forest Degradation and Deforestation

, 2023
AbstractTropical forests are being disturbed by deforestation and forest degradation at an unprecedented pace (Hansen et al. in Science 342:850–853, 2013; Bullock et al. in Glob Change Biol 26:2956–2969, 2020). Deforestation completely removes the original forest cover and replaces it with another land cover type, such as pasture or agriculture fields.
