ClearSpatiotemporal Differences in Marine Environment Quality in China and the Influencing Factors
Researchers analyzed panel data from 2011 to 2020 across China's coastal cities and provinces using the entropy method and Theil index to construct marine environment quality (MEQ) indicators and measure regional heterogeneity. The study applied a geographic detector model to identify driving factors and found MEQ increased in waves but remained relatively low, with a spatial pattern of higher quality in northern and southern regions.
Measurement and temporal and spatial characteristics of agricultural eco-efficiency under climate change: a case study of Anhui, China
Researchers applied super-efficient DEA-SBM analysis to measure agricultural eco-efficiency across Anhui Province, China, quantifying non-point source pollution from livestock breeding and chemical fertilizers. They found that eco-efficiency followed an 'inverted N' trend over time and exhibited spatial agglomeration patterns, with significant north-south regional differences driven by climate change and the 'Matthew effect.'
Integrating the water-energy-food nexus and LCA + DEA methodology for sustainable fisheries management: A case study of Cantabrian fishing fleets
Researchers evaluated the environmental efficiency of fishing vessels in northern Spain's Cantabrian fleet by combining life cycle assessment — a method that tallies all environmental costs from fuel to catch — with a statistical efficiency model. They found that over one-third of vessels were operating below peak efficiency, and that improving those inefficient boats could cut their environmental impact, including carbon emissions, by up to 65%.
The Driving Effect of Marine Industry on Marine Pollution: An Empirical Study from China
Researchers empirically examined the relationship between major marine industries and marine pollution levels in China, using national seawater quality classification data from the Ministry of Ecology and Environment. They found that marine industry activity has a measurable driving effect on marine environmental degradation, with different industries contributing distinct pollution impacts.
Green Efficiency Measurement of Seaweed Culture in China under the Double Carbon Target
This study measured the green efficiency of seaweed aquaculture in China in the context of carbon sequestration goals, finding variation across production regions. Sustainable seaweed cultivation can serve as an alternative to plastic-intensive conventional aquaculture, reducing ocean plastic inputs.
Conditions of Mainland China’s Island Ecosystems and Associated Influencing Factors: Integrated Assessment of 42 Typical Island Ecosystems
Researchers assessed the ecological condition of 42 representative islands along China's coast using a framework integrating environmental quality, biological structure, and landscape patterns, finding that island ecosystem health varied significantly by size, location, and human land use intensity.
Research on Financial Support, Technological Improvement and Marine Economic Development for China’s Coastal Regions
This study analyzed the relationship between financial support, technological improvement, and marine economic development in China's coastal regions. Despite significant government investment and technological advancement, marine industries still lag behind other sectors. The findings suggest that better targeted investment and technology transfer strategies are needed to fully develop China's blue economy.
Understanding the social–ecological systems of non-state seafood sustainability scheme in the blue economy
This review analyzed non-state seafood sustainability schemes as social-ecological systems, examining how eco-certifications and voluntary standards function within the blue economy and what factors determine their effectiveness at improving resource sustainability.
Can a “doughnut” economic framework be useful to monitor the blue economy success? A fisheries example
A doughnut economic framework was applied to assess the sustainability of purse-seiner fisheries in the northwestern Mediterranean Sea, revealing both ecological overshoot and shortfalls in basic social needs. The analysis demonstrated that achieving a sustainable sector requires not just technical and financial solutions but also sufficient social capacity for managing transition.
Spatiotemporal Evolution Characteristics and Obstacle Factors of the Coordinated Development between the Tourism Industry and Ecological Security
Researchers constructed an evaluation index system to measure the coordinated development between the tourism industry and ecological security in Zhejiang Province, China, analysing spatiotemporal evolution characteristics and identifying key obstacle factors. Findings revealed that tourism expansion initially exerts a coercive pressure on ecological security, with significant spatial heterogeneity shaped by population density and economic activity.
Multi-Criteria Relationship Analysis of Knowledge, Perception, and Attitude of Stakeholders for Engagement towards Maritime Pollution at Sea, Beach, and Coastal Environments
Researchers used multi-criteria analysis to assess the knowledge, perceptions, and attitudes of stakeholders toward marine pollution governance, finding persistent gaps between awareness and action, and identifying barriers to mobilizing the level of engagement needed for effective protection of vulnerable coastal ecosystems.
Ecological Security Evaluation of Marine Ranching Based on DEMATEL-Fuzzy Comprehensive Evaluation
This study developed a multi-factor scoring system to evaluate the ecological health and security of marine ranching areas in China. Marine ranching ecosystems are increasingly threatened by microplastic pollution, making ecological security assessments important for sustainable fisheries management.
Towards a meaningful assessment of marine ecological impacts in life cycle assessment (LCA)
Researchers reviewed how life cycle assessment (LCA) methods — used to quantify industrial environmental impact — currently lack adequate indicators for marine biodiversity loss, and identified pathways to build quantitative cause-effect models for seven major ocean stressors including plastic debris, ocean acidification, and seabed damage.
Analysis of the spatio-temporal evolution of sustainable land use in China under the carbon emission trading scheme: A measurement idea based on the DID model
Researchers applied a difference-in-differences estimation model to assess the effect of China's carbon emission trading scheme on sustainable land use across provinces from a spatio-temporal perspective. The scheme improved sustainable land use in pilot areas from both economic and environmental dimensions, with effects concentrated in eastern regions and urban agglomerations including the Pearl River Delta.
Assessing the impact of governance and health expenditures on carbon emissions in China: Role of environmental regulation
Researchers analysed the relationship between governance quality, health expenditures, environmental regulation, and carbon emissions in China from 1984 to 2018, finding an inverted U-shaped environmental Kuznets curve and that stronger environmental regulation helps decouple economic growth from carbon output.
Spatiotemporal Evolution of the Coupled and Coordinated Development of the Low-carbon Economy, Green Finance, and Ecological Environmental Quality: Evidence from China
Despite its title referencing low-carbon economy and ecological quality, this paper studies the coordinated development of green finance, carbon reduction, and environmental quality indicators across Chinese provinces — not microplastic pollution. It examines regional economic and environmental policy dynamics using statistical modelling, and is not relevant to microplastics or human health.
Development of a framework and toolbox for measuring and evaluating ecosystem interactions of seaweed aquaculture
This Dutch-language study (mostly in Dutch) developed a framework and toolbox for measuring ecosystem integrity in seaweed cultivation areas off the Dutch coast, relevant to scaling up sustainable aquaculture. Healthy coastal ecosystems with minimal microplastic contamination are important for sustainable seaweed production.
