Abstract In the context of climate change and sustainable development, there has been numerous researches studying influence land use policies on carbon sequestration. However, most them focus specific experimental area to explore impact fixation, or their impacts a certain aspect, lacking comprehensive explanation both internal mechanism external effects. Therefore, this article presents review results show that scientific have capacity increasing net sinks soil organic realize environmental sustainability. addition, these low‐carbon can not only bring out mitigation influence, but also effects cities food security, ecological protection, economic disparities promote development. if fail adapt local natural socio‐economic conditions, overlook potential negative they could pose, cannot facilitate achievement development even impede progress.

A growing world population means more food that needs to be provided. This in turn forces agriculture increase production and thereby emit greenhouse gases (GHG). study reveals there is a worldwide decrease climate environmental unit costs of producing agricultural raw materials, understood this article as the relationship between volume amount GHG emitted. In least developed countries (LDCs), land productivity was significantly lower over period 1961–2018 compared rest world. The reasons included adverse natural conditions capital shortages. Average consumption also lower, increased accompanied by population. contrast, were higher. differences dynamics phenomena are related its costs, both LDCs globally, reveal key solving conflict need necessity protection mainly modernisation providing it with appropriate technical equipment techniques such way satisfy most important irreducible nutritional purpose while minimising costs.

Estimation of carbon stock in the reed wetland of Weishan county in China based on Sentinel satellite series

Carbon Research, Journal Year: 2025, Volume and Issue: 4(1)

Published: March 11, 2025

Abstract Reed wetlands in Weishan County, Shandong provinces, are typical and representative wetland ecosystems with exceptional carbon sequestration potential. Evaluating the spatial temporal characteristics of land use stock these reed wetlands, exploring their sink value is crucial for climate change mitigation adaptation, provides a potential to as solution neutrality China. Using Sentinel active passive remote sensing data within Google Earth Engine (GEE) platform, we employed random forest classification method identify features County. By combining density obtained from bibliometric sources InVEST model, evaluated dynamics well other types. The results indicated that optical more effective than radar classification, achieving mean overall accuracy 89%. contribute significantly stock, accounting 28% total Other major contributors include forest, water body, agricultural land, artificial unused mudflat land. highest concentration found along shores four lakes northeastern mountainous areas capacity County expected generate 4.95–54 × 10 8 RMB, up 1%–12% county’s GDP. These findings provide scientific foundation subsequent restoration management efforts offer valuable insights developing relevant strategies.

Remote sensing and integration of machine learning algorithms for above-ground biomass estimation in Larix principis-rupprechtii Mayr plantations: a case study using Sentinel-2 and Landsat-9 data in northern China

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 13

Published: April 2, 2025

Estimating above-ground biomass (AGB) is important for ecological assessment, carbon stock evaluation, and forest management. This research assesses the performance of machine learning algorithms XGBoost, SVM, RF using data from Sentinel-2 Landsat-9 satellites. The study influence significant spectral bands vegetation indices on accuracy AGB estimate. results presented in paper indicate that were more effective than data. mainly because it had higher spatial resolution, which enabled model gradients structural attributes accurately. XGBoost performed best with an R 2 0.82 RMSE 0.73 Mg/ha 0.80 0.71 Landsat-9. In current study, SVM also showed a substantial 0.79 0.76 For Sentinel-2, random achieved 0.74 0.93 Mg/ha, Landsat 9 yielded 0.72 0.88 Mg/ha. Thus, variable importance analysis, have predicting AGB. As expected their application research, these predictors consistently emerged as highly across models datasets. demonstrates potential integrating remote sensing to achieve accurate efficient assessment.
