Research on the Spatiotemporal Evolution and Driving Factors of Forest Carbon Sink Increment—Based on Data Envelopment Analysis and Production Theoretical Decomposition Model

Forests, Journal Year: 2025, Volume and Issue: 16(1), P. 104 - 104

Published: Jan. 9, 2025

Forest carbon sinks play a crucial role in mitigating global climate change and enhancing ecological sustainability. This study utilizes the production theoretical decomposition analysis (PDA) model to develop framework for analyzing drivers of input–output dynamics within forest sink system. The specifically focuses on plant diseases insect pests as undesirable output indicators. We thoroughly analyzed development increment across Chinese provinces regions from 2010 2021, along with key influencing these changes. Policy recommendations are provided enhance scientific management promote sustainable development. results indicate following: (1) China its three major have increased annually, dynamic fluctuations increments. overall center gravity has shifted southwest northeast. (2) rate varies regions, 93.548% all showing positive growth. eastern region is significantly higher than western central regions; (3) Technological changes positively impacted enhancement China. However, technical efficiency had significant negative effect, intensity may become driver inhibiting future enhancement.

Multi-scenario land use change simulation and spatial-temporal evolution of carbon storage in the Yangtze River Delta region based on the PLUS-InVEST model

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(1), P. e0316255 - e0316255

Published: Jan. 24, 2025

Influenced by urban expansion, population growth, and various socio-economic activities, land use in the Yangtze River Delta (YRD) area has undergone prominent changes. Modifications have resulted adjustments to ecological structures, leading subsequent fluctuations carbon storage. This study focuses on YRD region analyzes characteristics of changes using data from 2000 2020, with a 10-year interval. Utilizing InVEST Model’s Carbon Storage module combination PLUS model (patch-generating simulation), we simulated projected future patterns storage across under five scenarios including natural development (ND), (UD), protection (EP), cropland (CP), balanced (BD). Upon comparing levels predicted for 2030 those stocks decrease initial four then increase fifth scenario. In declining scenarios, CP scenario had least reduction storage, followed EP The implementation policies aimed at safeguarding preserving integrity can efficaciously curtail expansion developed into woodland cropland, enhance structure use, mitigate loss

Analysis of the Spatiotemporal Changes in Cropland Occupation and Supplementation Area in the Pearl River Delta and Their Impacts on Carbon Storage

Land, Journal Year: 2024, Volume and Issue: 13(8), P. 1195 - 1195

Published: Aug. 3, 2024

In recent years, the “dual carbon” issue has become a major focus of international community. Changes in land use driven by anthropogenic activities have profound impact on ecosystem structure and carbon cycling. This study quantitatively assesses spatiotemporal changes cropland occupation supplementation Pearl River Delta from 2000 to 2020 using InVEST model, analyzing spatial clustering storage caused variations area. The PLUS model was employed simulate land-use patterns distribution four future development scenarios. results indicate following: (1) From 2020, net change rate area −0.81%, with decrease 16.49 km2 area, primarily converted built-up forest land. (2) Carbon exhibited pattern lower values center higher periphery. terrestrial 534.62 × 106 t 2000, 518.60 2010, 512.57 showing an overall decreasing trend. conversion main reason for decline total regional storage. (3) sequestration lost due significantly greater than loss compensated new cropland, indicating imbalance quality as crucial factor contributing loss. (4) Under ecological priority scenario, expansion reduction such were effectively controlled, resulting minimal soil organic pool is most active ecosystems significant Clarifying relationship between “cropland protection measures–land changes–ecosystem storage” will improve policies, provide references enhancement, support sustainable socio-economic development.

Constructing Soils to Mitigate Land Occupation by Urban Expansion and Metabolism to Improve Healthy Cities

Land, Journal Year: 2024, Volume and Issue: 13(9), P. 1383 - 1383

Published: Aug. 28, 2024

The number of city residents worldwide is increasing at the same that soil consumption around cities, which can be mitigated using technosols. Urban areas need to provide a healthy environment for residents, but this threatened by climate change. Mitigating adverse impacts change does not involve one-size-fits-all global solutions; cities face varying economic and social contexts. Cities offer ecosystem services in order operate as urban ecosystems. soils’ environmental are often overlooked, leading public administrations having little no awareness about land management policies services. Technosols, artificial or human altered soils, have potential benefits natural soils do require much time develop perform their functions. Additionally, technosols enhance circular economy waste materials. In sense, policy makers should incorporate strategy health address Our perspective on needs altered, included policies, serve crucial component providing acting carbon sink well-being.

Enhancing Forestation Carbon Sinks in China: A Comparative Analysis of New and Traditional Market Incentive Frameworks

Published: Jan. 1, 2024

New markets for ecosystem services have been proposed as a way to diversity landowner's revenues from forestation. This study examines differences in China's forestation carbon sinks under new and traditional market incentive frameworks. We found that China could biophysically sequester 209.77 Mt CO2 annually through forestation, but due lower prices, only less than 40% of this potential was currently investable. Under the scenario, investable area, sink potential, costs were roughly double, 1.32 times, half those observed market, respectively. intensity reforestation 1.54 times great afforestation, with its being about afforestation's. These findings can provide valuable recommendations policymakers.
