Forest vs Savanna dynamics in the contact zones of French Guiana

Revue Française de Photogrammétrie et de Télédétection, 2014
Savannas and tropical forests delineated by sharp boundaries are two alternative stable ecosystems. What is the natural evolution of forests over savannas in coastal savanna in French Guiana?

Application of Object Based Classification and High Resolution Satellite Imagery for Savanna Ecosystem Analysis

Remote Sensing, 2010
Savanna ecosystems are an important component of dryland regions and yet are exceedingly difficult to study using satellite imagery. Savannas are composed are varying amounts of trees, shrubs and grasses and typically traditional classification schemes ...

Reframing tropical savannization: linking changes in canopy structure to energy balance alterations that impact climate

Ecosphere, 2020
Tropical ecosystems are undergoing unprecedented rates of degradation from deforestation, fire, and drought disturbances. The collective effects of these disturbances threaten to shift large portions of tropical ecosystems such as Amazon forests into ...

Terrestrial Laser Scanning for Vegetation Analyses with a Special Focus on Savannas

Remote Sensing, 2021
Savannas are heterogeneous ecosystems, composed of varied spatial combinations and proportions of woody and herbaceous vegetation. Most field-based inventory and remote sensing methods fail to account for the lower stratum vegetation (i.e., shrubs and ...

Savanna burning methodology for fire management and emissions reduction: a critical review of influencing factors

Carbon Balance and Management, 2016
Savanna fire is a major source of global greenhouse gas (GHG) emissions. In Australia, savanna fire contributes about 3% of annual GHG emissions reportable to the Kyoto Protocol.

A model inter-comparison study to examine limiting factors in modelling Australian tropical savannas [PDF]

Biogeosciences, 2016
The savanna ecosystem is one of the most dominant and complex terrestrial biomes, deriving from a distinct vegetative surface comprised of co-dominant tree and grass populations.

Identification of hydropedological flowpaths in Stevenson–Hamilton catena from soil morphological, chemical and hydraulic properties

Koedoe: African Protected Area Conservation and Science, 2020
In highly variable water regimes of semi-arid savannahs, water is the key driving force for biotic and abiotic processes. Understanding and measuring components of the hydrological cycle at landscape scale is however difficult because of the ...

Challenges and opportunities in modelling savanna ecosystems [PDF]

, 2016
Abstract. The savanna complex is a highly diverse global biome that occurs within the seasonally dry tropical to sub-tropical equatorial latitudes. Savannas are open-canopy environments that encompass a broad demographic continuum, often characterised by a dynamically changing dominance between C3-tree and C4-grass vegetation, where frequent ...
