Exploring the spatial distribution of land use/cover change (LUCC) and ecosystem carbon storage under future climate scenarios can provide scientific basis for optimizing resource redistribution formulating policies sustainable socioeconomic development. We proposed a framework that integrates patch-generating use simulation (PLUS) model integrated valuation services tradeoffs (InVEST) to assess spatiotemporal dynamic changes in LUCC Guangdong based on shared pathways representative concentration (SSP-RCP) provided by Coupled Model Intercomparison Project 6 (CMIP6). The results showed patterns were similar SSP126 SSP245 scenarios, but artificial surface expanded more rapidly, increase forest slowed down SPP245 scenario. Conversely, SSP585 scenario, sharply resulted continuous decrease land. Under three population, elevation, temperature, distance water highest contributing driving factors growth cultivated land, grassland, surface, respectively. By 2060, terrestrial ecosystems increased from 240.89 Tg 2020 247.16 243.54 respectively, which 17.65 15.34 Tg, respectively; while it decreased 226.54 due destruction accounted 81.05% total storage. Overall, an important recommendation this study is be controlling population economic growth, balancing urban expansion ecological conservation, as well increasing area.

Effects of land use/cover change on carbon storage between 2000 and 2040 in the Yellow River Basin, China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 151, P. 110345 - 110345

Published: May 11, 2023

Land use/cover change (LUCC) is the primary source of carbon storage changes in ecosystem. Up to now, there are few studies about impacts and driving mechanisms LUCC for ecosystem at spatial–temporal scales. Characterizing Yellow River Basin (YRB) its role very important necessary elucidate results human activities on ecosystems. The policies address potential future risks should be formulated advance achieve effective development. In paper, we regarded YRB as study area, analyzed during 2000 2020, predicted land use patterns 2040 under scenarios natural trend (NT), ecological degradation (ED), restoration (ER) using Markov model with Patch-generating Use Simulation (PLUS) model, quantified ecosystems over last 20 years according Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model. outcome was follows: (1) During 2040, changed markedly, cropland being transformed into woodland, grassland built-up land; (2) an upward a mean annual increase 1.93×106Mg C, woodland answer increasing storage, while unused could induce decrease; (3) Carbon varied different degrees three scenarios, but premise not causing large-scale damage, conversion means improving greatly enhancing sequestration efficiency capacity YRB. conclusion, environmental management continuously oriented protection low-carbon development, so that basin will able develop benign direction.

Nature-based Solutions can help restore degraded grasslands and increase carbon sequestration in the Tibetan Plateau

Communications Earth & Environment, Journal Year: 2024, Volume and Issue: 5(1)

Published: March 26, 2024

Abstract The Tibetan grassland ecosystems possess significant carbon sink potential and have room for improved sequestration processes. There is a need to uncover more ambitious coherent solutions (e.g., Nature-based Solutions) increase sequestration. Here, we investigated the rationale urgency behind implementation of Solutions on sequestering using literature review meta-analysis. We also project changes in terrestrial Plateau model simulations with different future emissions scenario. results show that Solution projects are expected by 15 21 tetragrams 2060. defined conceptual framework integrates initiatives restoration degraded grasslands Our consists four stages: theory, identification, practice, goal. Traditional knowledge plays an important role reframing proposed framework. apply this optimize ecological techniques evaluate annual under socioeconomic pathway scenarios.

Published: March 1, 2021

The past decades were witnessing unprecedented habitat degradation across the globe. It thus is of great significance to investigate impacts land use change on quality in context rapid urbanization, particularly developing countries. However, rare studies conducted predict spatiotemporal distribution under multiple future scenarios. In this paper, we established a framework by coupling simulation (FLUS) model with Intergrated Valuation Environmental Services and Tradeoffs (InVEST) model. We then analyzed Dongying City 2030 four scenarios: business as usual (BAU), fast cultivated expansion scenario (FCLE), ecological security (ES) sustainable development (SD). found that City, driven urbanization agricultural reclamation, was mainly characterized transfer land, construction unused land; area significantly reduced. While showed degradative trend from 2009 2017, it will be improved 2017 high-quality distributed Yellow River Estuary coastal areas, areas low-quality concentrated central southern regions. Multi-scenario analysis shows SD have highest quality, while BAU lowest. interesting ES fails capacity protect which may related excessive saline alkali land. Appropriate reclamation conducive protection food security, but also improving giving play versatility multidimensional value landscape. This comprehensive coordination urban development, an effective way maintain biodiversity.

The Tibetan Plateau has a large area of marshes which play crucial part in the global carbon cycle. vegetation aboveground biomass (AGB) is critical indicator storage marsh ecosystems. Due to limitations field investigation, spatiotemporal variation AGB and its influencing factors remain unclear. By using normalized difference index (NDVI), climate measured data, this study investigated temporal spatial response change during 2000–2019. results showed good correlation between annual maximum NDVI (NDVImax), can be accurately estimated from power function equation NDVImax (Y = 343.08 × NDVImax0.7363). Based on equation, we found that density increased significantly (4.10 g·C/m2/decade) 2000 2019 over Plateau, with an average value 184.71 g·C/m2. In terms effects, precipitation July could increase AGB, while other months no significant effect Plateau. This first asymmetric impact night day temperature marshes: warming day-time no-significant night-time marshes. Considering background nighttime daytime, more attention should paid different impacts temperatures
