Yet, the behavioral drivers of protective measures remain poorly understood, particularly in North India, where intensive agriculture has degraded the agroecosystem. This study investigated farmers' protective behavior (PB) through the Health Belief Model (HBM) using an integrated framework that combines Partial Least Squares Structural Equation Modeling (PLS-SEM) with Fuzzy-Set Qualitative Comparative Analysis (fsQCA). Field survey data from the Hindon River Basin revealed widespread use of hazardous insecticides (WHO Class Ia, Ib, and II; &gt;7 applications/season), poor adoption of personal protective equipment (PPE), and unsafe handling and disposal practices, leading to acute health symptoms including skin and eye irritation, headaches, and dizziness. Although most farmers recognized the health risks from pesticide exposure, awareness of environmental impacts remained limited. PLS-SEM findings indicated that cues to action (β = 0.228, <em>p</em> &lt; 0.01), self-efficacy (β = 0.188, <em>p</em> &lt; 0.05), and perceived benefits (β = 0.182, p &lt; 0.05) significantly promoted PB, whereas higher perceived barriers and perceived severity had negative effects; perceived susceptibility showed no direct effect. fsQCA demonstrated its indirect role and identified combinations of high perceived susceptibility, perceived benefits, self-efficacy, and education as the most effective pathways for strengthening PB. Self-efficacy emerged as a core condition for safe behavior, while the absence of cues to action was linked to unsafe practices. These findings highlight the need for targeted, group-specific interventions such as training, awareness, and regulatory measures to inform integrated environmental health policies in similar agricultural contexts across developing countries.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"117 ","pages":"Article 108193"},"PeriodicalIF":11.2,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145155230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spatially, the degree of isolation exhibited a distinct pattern, being higher in ecological sources near built-up urban areas and lower in densely clustered ecological sources. In addition, divergent characteristics were observed among urban growth patterns (UGPs). Outlying growth contributed the most to habitat isolation, with a steadily increasing share over time. In contrast, edge-expansion and infilling growth showed relatively smaller and gradually declining contributions.

The framework is used to further optimize the ESP through <em>finite-element simulations</em> via multiple scenario analyses. Corridors with potential instability (e.g., high stress concentration and deformation) are identified through structural analysis, with corridor B exhibiting the maximum deformation (0.734 m) and significant stress concentration (200 MPa), indicating vulnerability to environmental disturbances. Multi-scenario simulations reveal that stepping stones enhance corridor resilience, but their placement may destabilize adjacent corridors, necessitating strategic spatial planning.

While the traditional Environmental Kuznets Curve (EKC) hypothesis is rejected, the AEKC is confirmed, suggesting that environmental improvements can eventually occur with continued agricultural growth. The sectoral analysis reveals varying environmental impacts: the standard EKC is observed exclusively in the fishery sector, while the AEKC is validated solely in the crop sector. The animal sector is U-shaped, becoming significant in the long run.

In this paper, we developed an updated time-series (yearly from 2005 to 2023), bottom-up (using source-level emission profile), full-scale (including fossil fuel combustion sectors, and industrial processes and indirect emissions sectors) CO₂ emission inventory covering all Chinese cities (including 339 prefecture-level cities), by using a hybrid method covering big data analysis, remote sensing applications, and GIS technology. It showed that overall CO₂ emissions in Chinese cities grew steadily from an average of 20.64 million tons in 2005 (95 % CI 0.25–88.68 million tons) to 37.80 million tons in 2020 (95 % CI 1.39–164.36 million tons), driven mainly by emissions from industrial and indirect sectors (increase by 12.45 and 21.63 million tons). We also identified an unexpected reversal in emission status from 2020 to 2023, with 65 cities shifting back from previously decline or plateau status to growth status, reversing earlier progress. Meeting China's 2030 peak emissions target will require stricter emission reduction scenarios, with significant reductions in emissions from the industrial and power sectors, as well as indirect emissions (collectively accounting for 1739 million tons of reductions between 2023 and 2035), aiming to achieve at least the 60th percentile of the corresponding benchmark. Our paper advocates for the implementation of a real-time carbon emission monitoring system at the local government level and suggests that high-emission cities could achieve noticeable reductions in emissions by adopting benchmark emission performance standards from their peer cities, while simultaneously exploring low-carbon development pathways.

Carbon mineralization presents a promising pathway for emission reduction across the lifecycle of cement and cement-based materials (CCM). This study systematically evaluates the mineralization potential of CCM by integrating reaction mechanisms, sequestration efficiencies, techno-economic constraints, and policy considerations. The process is thermodynamically favorable and kinetically tunable, converting CO<sub>2</sub> into stable CaCO<sub>3</sub> through reactions with Ca(OH)<sub>2</sub>, C-S-H, and unhydrated clinker. Distinct carbonation mechanisms operate at different stages—early-age carbonation during mixing, strength and durability gains during curing, and pore filling in recycled aggregates at end-of-life. Sequestration efficiency varies by stage: low in mixing (0.616–2.21 kg/m<sup>3</sup>), high in curing (35.0–113.47 kg/m<sup>3</sup>), and moderate in RCA treatment (16.9–58.0 g/kg aggregates). Co-sequestration of NO<sub>x</sub> and SO<sub>x</sub> further enhances environmental performance, though challenges such as gas diffusion limitations and competitive adsorption persist. While natural carbonation offsets 30–55 % of process emissions, fully scaled accelerated carbonation could sequester up to 483 Mt. CO<sub>2</sub> annually. Industrial application remains limited by CO<sub>2</sub> capture logistics, flue gas purity, and infrastructure demands. High capital costs—especially for curing systems—require supportive policy, carbon pricing, and optimized logistics. Life cycle assessments (LCA) confirm environmental benefits, especially with CO<sub>2</sub> curing. However, successful large-scale implementation will require coordinated innovation in materials science, process design, and regulatory frameworks to realize the full mitigation potential of CCM-based mineralization technologies.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"117 ","pages":"Article 108171"},"PeriodicalIF":11.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145105786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
