Multi-Criteria Decision Analysis to Evaluate Sustainability and Circularity in Agricultural Waste Management

Sustainability, Journal Year: 2023, Volume and Issue: 15(20), P. 14878 - 14878

Agriculture is a major contributor to global anthropogenic emissions, such as waste production and greenhouse gases. In order reduce these negative impacts, circular economy should be applied agriculture management. Processes for evaluating treatment valorization options are fundamental the implementation of long-term, economically viable, ecologically sound, socially acceptable policies practices. this field, multi-criteria decision analysis methods (MCDAs) can offer holistic perspective on decision-making processes. This study deeply explores area research by conducting an extensive critical review studies that have used MCDA approaches support agricultural The aim better understand how been (in integrated manner or complementary approaches) stakeholders involved. conducted underlines MCDAs now widely in area, well being increasingly multi-methodologies. part ongoing Next-Generation-EU-integrated, large-scale, multi-disciplinary program, National Research Centre Agricultural Technologies.

Integrated approach for ecological restoration and ecological spatial network optimization with multiple ecosystem functions in mining areas

Ecological Indicators, Journal Year: 2023, Volume and Issue: 156, P. 111141 - 111141

Published: Oct. 31, 2023

The transformation of the landscape structure in mining cities is influenced by a combination various factors, resulting decline ecological quality and an increased vulnerability environment. ecology directly impacts flow transmission ecosystem functions, underscoring need for careful consideration establishment networks. In this study, analysis was conducted using land-use data from 2005 to 2020 Linfen City, Shanxi Province, China. A network optimization strategy established, focusing on capacity self-restoration connectivity patches. Additionally, spatiotemporal characteristics risk between were examined. Taking into account influence value resilience ecosystem, Minimum Cumulative Resistance (MCR) model employed construct network. structural explored complex methods. addition, based functionality (EC) adopted, comparing robustness before after optimization, it found that method enhanced smoothness energy transfer interconnectivity among nodes network, significantly stability Within study area, local levels due coal urban expansion.

Flood risk transfer analysis based on the “Source-Sink” theory and its impact on ecological environment: A case study of the Poyang Lake Basin, China

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 921, P. 171064 - 171064

Published: Feb. 23, 2024

Driven by climate change, the frequent occurrence of regional destructive floods poses a grave threat to socio-economic systems and ecological environments. Previous flood risk studies have disregarded transfer within region, resulting in inadequate assessment ineffective disaster prevention mitigation outcomes. Therefore, this study introduced "Source-Sink" theory into field constructing model. Flood was conducted Poyang Lake Basin, China, where impacts initial statuses on ecosystem service values were quantified. The results showed that Basin relatively low, with high spatial distribution characteristics central-north areas but low surrounding areas. High-risk zones mainly distributed southwest Lake. lower-risk exhibited contiguous surrounded higher-risk zones. Following completion transfer, high-risk increased significantly; there few transferred other zones, thereby lowering their risks. occurs primarily low- medium-risk being most important growth targets. change evident area Lake, while Upper Gan River lower less sensitive effect. Accounting for risk, decreased 8.18 %, significant observed environment After value declined 24.66 %. This provides reference point management sustainable development account transfer.

Since 2016, the Ministry of Ecology and Environment Beijing Municipal Government have adjusted minimum concentration limit for ambient air dustfall several times, indicating that they attach great importance to dustfall. To grasp pollution characteristics sources dustfall, in this work, filtration method was used determine insoluble water-soluble urban area Beijing. From our analysis, influence meteorological parameters on found, chemical components were determined. The positive matrix factorization (PMF) model also utilized analyze results indicated average amount 2021–2022 4.4 t·(km2·30 d)−1, proportion deposition 82.4%.
