Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Species level mapping of forest canopy height in Nepal using GEDI with Sentinel-1 and Sentinel-2

Frontiers in Remote Sensing
Forest canopy height mapping is critical for mapping and modeling bio-geophysical and ecological factors, including forest aboveground biomass, carbon reserves, forest carbon emissions, habitat diversity, forest degradation, and restoration success.

Impacts of Climate Change on Food Security: Land Management–Based Strategies Within a Nature‐Based Solutions Framework

Land Degradation &Development, EarlyView.
ABSTRACT Climate change poses serious threats to food security by affecting agricultural production processes in multiple ways. This study aims to analyze land management–based solution strategies that can be developed in response to this threat and presents a systematic and holistic framework through the relationship these strategies establish with ...

Canopy height damage by Typhoon Songda in Northern Hokkaido, Japan, in 2004

Environmental Research: Ecology
The increasing need for the risk assessment of disastrous wind disturbance, especially by tropical cyclones (TCs), has been emphasized because the number of intense TCs is projected to increase due to global warming, though there are some discrepancies ...

Post-drought decline of the Amazon carbon sink [PDF]

, 2018
Amazon forests have experienced frequent and severe droughts in the past two decades. However, little is known about the large-scale legacy of droughts on carbon stocks and dynamics of forests.

Uncertainties in Forest Canopy Height Estimation From Polarimetric Interferometric SAR Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
The random volume over ground (RVoG) model has been widely applied to estimate forest tree height from polarimetric synthetic aperture radar (SAR) interferometry (PolInSAR) data for the past two decades. Successful application of the RVoG model requires certain assumptions to be valid for the imaged forest and the acquisition scenarios in order to ...

A Field Guide for Soil Erosion Risk Assessment in Olive Orchards Across Mediterranean Conditions for End‐Users and Stakeholders

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion control poses a crucial challenge to the sustainability of Mediterranean olive groves. To facilitate field‐level decision‐making, we have developed a field guide oriented to use in any type of olive orchard across the Mediterranean.

The use of sun elevation angle for stereogrammetric boreal forest height in open canopies

Remote Sensing of Environment, 2017
Stereogrammetry applied to globally available high resolution spaceborne imagery (HRSI; < 5 m spatial resolution) yields fine-scaled digital surface models (DSMs) of elevation. These DSMs may represent elevations that range from the ground to the vegetation canopy surface, are produced from stereoscopic image pairs (stereopairs) that have a variety of ...

Breynia phuongiana (Phyllanthaceae), a new species from the Central Highlands of Vietnam

Nordic Journal of Botany, EarlyView.
A new species, Breynia phuongiana (Phyllanthaceae subgen. Sauropus), is described and illustrated from the Central Highlands of Vietnam. It is morphologically similar to B. beillei, B. bonii, and B. thorelii, but differs in having oblong‐elliptic leaves, sepals marked with reddish striations, an androphore exceeding 1 mm in length, and distinctly ...
