Carbon Storage and Carbon Dioxide Sequestration by Urban Tree Cover: Case Study From Varanasi, India

Tree species in urban areas have a huge ability to reduce emissions due to carbon sequestration. However, only a few studies on the quantification of carbon stock in urban vegetation are so far out. For improved monitoring and management of regional carbon stock, there is also the need to quantify the amount of sequestered carbon in urban tree canopy for improved monitoring and management. We examine the possibility of carbon dioxide sequestration in trees at a few locations in Varanasi's densely populated city. Both above-ground and below-ground biomass in various locations had averaged 1901 metric tonnes of carbon per hectare, with carbon dioxide sequestration of 6977 tonnes per hectare, according to our report. Urban tree plantations have a significant ability to sequester anthropogenic carbon locally grown and to store it in their biomass for long stretches of time, according to this.

Variations in trade-off of carbon storage and growth in subalpine larch across an elevational gradient

For subalpine larch trees to thrive at the treeline, a ratio of storage to expansion of at least 8. 4 and a balancing storage-growth relationship could be advisable. Abstract At their upper elevation range limits, cold-adapted trees tree trees exhibit acclimation in the trade-off between carbon storage and expansion under freezing conditions. We investigated the spatial distribution of treeline tree species Larix chinensis along an elevation gradient in north-central China's Qinling Mountains, looking at the physiological mechanism of treeline generation from carbon exchange. According to this, we found that a ratio of storage to growth of at least 8. 4 could be important for subalpine larch trees to survive at their low-temperature edge. Therefore, for subalpine larch trees to survive and grow in the altitudinal treeline ecotone, a proper carbon storage-growth ratio and a balanced storage-growth relationship may be required.

A global assessment of the mixed layer in coastal sediments and implications for carbon storage

Both particulate and dissolved matter in coastal interfaces are controlled by processes in the sediment mixed layer. Here we map the global distribution of the coastal SML based on excess 210 Pb data and then use a neural network model to upscale these results. Organic matter preservation and SMLs are inversely related as mixing encourages oxidation in sediments, which promotes organic matter decomposition. Lower organic carbon absorption rates and total organic carbon/specific surface area ratios are found at sites with SML thickness > 60 cm.
