A System Dynamics Model of Soil Carbon Stock and Flows in Grasslands Under Climate and Grazing Scenarios.
<p>Carbon sequestration is paramount to reducing climate change. Grasslands, representing 40% of all terrestrial area, can serve as a primary sequestration location if optimal management strategies can be realized. This study used system dynamics modeling to examine the temporal dynamics of carbon …

Assessment of carbon stock and selected soil fertility indicators in a bush encroached savanna at Erichsfelde farm, Namibia
… bush encroachment offers potential woody carbon stock storage, which can render Namibia a net carbon sink. This study was, therefore, aimed at quantifying potential woody carbon stock storage from different pools and assessing selected soil fertility indicators in low, medium and high …

Anthropogenic impacts on Cerrado conservation and biodiversity and carbon restoration of Atlantic Forest
… for changes in ecosystem functions, including carbon stock, which is important for mitigating climate change. However, anthropogenic impacts on biodiversity conservation of Cerrado and Atlantic Forest restoration, two Brazilian hotspots for biodiversity conservation in the world, remains poorly …

A study on above- and belowground biomass and carbon stocks as well as sequestration of mountain birch (Betula pubescens Ehrh.) along a chronosequence in southern Iceland
… because vegetation represents an important carbon sink. The aims of the study are how above- and belowground woody biomass and organic carbon is accumulated along a chronosequence in South Iceland and how afforested and remnant mountain birch areas react as carbon sinks. In summer 2009, 31 …

Accelerating the delivery of climate targets: Technology and behaviour in the road to net zero
… the recent growth of wind power. Future decarbonisation will be more challenging. Interdisciplinary collaboration, between scientists, engineers and economists among others, is necessary to overcome our carbon addiction. This thesis asks how best to achieve urgent mitigation. It focuses on …

Spatiotemporal dynamics of carbon cycling and thermokarst in response to climate and fire-regime changes in the Arctic tundra biome
… functions of tundra ecosystems, including soil carbon stock, permafrost stability and vegetation types. However, it remains poorly understood how tundra ecosystems will feedback to the combined forces of changing climate and fire disturbance. In this study, I integrated paleoecology, numerical …

Forest and woodland regeneration dynamics and persistence in the human- modified landscape of Greater Gombe Ecosystem, Tanzania
… persistence and recovery of forest structure, carbon stock, and feeding habitat quality for vulnerable species, such as chimpanzees. To properly assess the influence of this management strategy, we need to take into account other factors likely to affect forest attributes, including, …

An assessment of critical carbon services and water resources in South Africa’s terrestrial protected area network
… protected area network in protecting strategic carbon and water services, which are important for climate change resilience. My first question investigated how well the country's PAs perform regarding the area coverage of carbon stocks and Strategic Water Source Areas (SWSA). My second question …

Optimising carbon storage by land-management
… recognising the importance of soil organic carbon (SOC), and its need for preservation. To establish if land-management could be optimised to increase carbon storage, ‘The Wallington Carbon Footprint Project’ was implemented. This study aimed to measure the Wallington Estate’s carbon stock, …

The role of NGOs and sustainability standards in oil palm developments in Gabon and Cameroon
… are in the process of being reviewed. The 'High Carbon Stock' concept is being adapted by a group of companies and the accompanying carbon stock thresholds somewhat relaxed. It is vital to understand the potential spatial implications of these changes in terms of environmental outcomes and to be …

SOIL ORGANIC CARBON IN MID-ATLANTIC REGION FOREST SOILS: STOCKS AND VERTICAL DISTRIBUTION
… contains the largest terrestrial pool of organic carbon (Boschi et al., 2018) and temperate forest soils have been a major sink for atmospheric carbon; however, determining the size of the soil organic carbon stock can be problematic. Sampling practices vary for sampling depth, and determining the …

Carbon fluxes from tropical peatlands : methane, carbon dioxide, and peatland subsidence
… peatlands in Southeast Asia have sequestered carbon over thousands of years and are an important global carbon stock. In natural peat swamp forests, high water levels inhibit decomposition due to anoxic conditions. However, they are being rapidly deforested and drained, releasing stored carbon …

Tree-ring analysis and stem biomass estimation of limba (Terminalia superba Engl. & Diels) in the framework of sustainable forest management
… data on tree growth, wood production and carbon stocks hampers the implementation of sustainable forest management and possible financing by Kyoto Protocol related tools like REDD+ and Clean Development Mechanisms. Africa is the continent with the lowest percentage of sustainably managed …

Variabilité de la respiration hétérotrophe du sol dans des écosystèmes agricoles: Analyse à différentes échelles spatiales et temporelles.
… CO2 fluxes in the incubation experiment, where carbon substrate was limited, suggested that temperature played a role both directly (enzymatic response) and indirectly (labile carbon stock depletion) at a relatively short term, and confirmed the hypothesis of occurrence of abiotic fluxes linked …

Real Options Analysis of Carbon Forestry Under the New Zealand Emissions Trading Scheme
… Trading Scheme (NZETS), designed to create a carbon price in the economy. Under the NZETS, new forests planted on and after 1st January 1990 (known as post-1989 forests) are eligible to earn carbon credits and sell them domestically and internationally, with a condition that the credits will …

Tracking Forest Height Growth Over Time with ICESat-2 ATL08
… for forest inventory, growth prediction, and carbon stock estimates. Since late 2018, the ICESat-2 mission has employed a photon-counting LiDAR system to estimate along-track ground and canopy heights above the WGS 84 ellipsoid. This mission provides repeat coverage in 100 m data segments …

EVALUATING THE PERFORMANCE OF BIOMETRIC APPROACHES FOR VERIFICATION AND MONITORING IN COMMERCIAL FOREST CARBON ACCOUNTING
Of the strategies to increase land carbon storage and avoid GHG emissions through natural ecosystem management, Forest-based Climate Solutions (FbCS) are believed to offer the greatest mitigation potential. As more funds are allocated towards FbCS deployment, questions arise regarding their actual …

LINKING ALLOMETRIC SCALING THEORY WITH LIDAR REMOTE SENSING FOR IMPROVED BIOMASS ESTIMATION AND ECOSYSTEM CHARACTERIZATION
Accurate quantification of forest carbon stocks and fluxes is critical for the successful modeling and mitigation of climate change. This research focuses on forest carbon stock quantification, both in terms of testing emerging remote sensing approaches to forest carbon modeling, and examining …
