This unique ownership model, where the Indian Government owns the forested land, but trees on that land are customarily owned by the households or community, plays a critical role in community participation in Participatory Forest Management (PFM). No study has yet quantitatively analyzed the relationship between customary ownership over trees and participation in PFM activities. Therefore, this study fills this gap by analyzing the relationship between households' participation in PFM, the number of trees under customary ownership on forested public lands, and socioeconomic variables in Jharkhand, India. Data were collected through semi-structured interviews and participatory rural appraisal. Factor analysis and multivariate linear regression were employed to analyze this relationship. We found that households' customary ownership over a higher number of trees enabled them to earn a higher income and motivated them to relocate for better education and healthcare access, resulting in reduced PFM participation. Households with larger forest landholdings participated more regularly in PFM activities, motivated to legalize ownership of their long-used forestlands. Displaced households experienced reduced PFM participation. Higher caste and wealth groups were associated with greater PFM participation due to better resource access and stronger decision-making power. The study findings inform policymakers to improve inclusive participation in PFM activities and provide a pathway for achieving India's environmental commitments by reducing socioeconomic disparities, improving tribal livelihoods, and promoting sustainable management of forestry resources.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143472125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dissolved organic carbon (DOC) transport from forests significantly impacts drinking water quality since it interacts with chlorine to form disinfection byproducts. Although the Soil and Water Assessment Tool-Carbon (SWAT-C) has been widely used to understand carbon fluxes at the watershed scale, the model has been primarily evaluated in non-forested watersheds and loading to aquatic systems, often overlooking terrestrial carbon fluxes from forested regions within watersheds of interests. This study assessed the applicability of SWAT-C in simulating carbon fluxes in both terrestrial and aquatic systems in the forested Big Creek watershed located in the south-central United States (U.S.), which also serves as a drinking water source, and analyzed dominant pathways of DOC transport across the landscape. Additionally, three management scenarios (i.e., forest conversion, raking in forests, and adjusting biomass harvest in croplands) aimed at reducing DOC transport were evaluated. Calibration efforts using remotely sensed as well as datasets demonstrated the proficiency of SWAT-C in simulating both terrestrial and aquatic carbon fluxes in forest-dominated regions. Results emphasize the importance of initializing and calibrating the parameters of dominant land use/cover types to enhance model performance in simulating carbon fluxes. The study found that all evaluated management scenarios can reduce DOC transport into streams, with the conversion of the dominant loblolly pine forests to restored longleaf pine forests achieving a 40% reduction in forest-derived DOC yields. These findings offer valuable insights for watershed-scale carbon cycling modeling and inform management strategies in forest-dominant watersheds to mitigate DOC yields.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explore these challenges in Nepal, where more than 450 EIAs have been approved since 1997. However, existing EIA evaluations and procedures are widely recognized as failing to deliver on-the-ground. We provide the first public dataset of hydropower projects with approved EIA's, as a basis for characterizing the state of EIA implementation in Nepal. Based on a purposive sample of hydropower EIA reports, we highlight 26 commonly-proposed mitigation measures, and examine the thoroughness of these reports as written. We then also evaluate whether and how these proposed mitigation measures were implemented, based on independent, field-based evaluations of 9 projects, including interviews with field staff and local residents. The results show strong patterns of incomplete and non-compliance EIA reports, particularly as relates to mitigation measures. In the field, we document low levels of implementation of proposed mitigation measures, as well as blatant violations of best practices, and very low rates of government monitoring (~15% of approved projects).

Utilizing a cross-sectional research design, we collected primary data from 162 households affected by mining activities through systematic random sampling. Additionally, qualitative data were gathered through four focus group discussions (FGDs) and twelve key informant interviews (KIIs). Quantitative data were analyzed using descriptive statistics, while qualitative data underwent narrative analysis. The findings indicate low levels of public involvement in land allocation, ESIA processes, and decision-making related to mining investments. Furthermore, weak institutional monitoring has hindered effective implementation of ESMEP by mining companies. Consequently, affected communities face significant risks of adverse social and environmental impacts that threaten their sustainable development. To address these issues, the study recommends that the regional government establish robust institutions for monitoring and evaluating ESIA and ESMEP implementation, thereby ensuring accountability among mining companies and fostering sustainable development within host communities.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, clean growth initiatives can create cumulative effects. Moreover, such initiatives are evolving rapidly and it is unclear if conventional environmental assessments are sufficient. The assessment of cumulative effects of clean growth remains a relatively novel activity, yet is seemingly important given that some of the emerging actions and technologies could themselves yield a variety of unanticipated environment impacts. To support evidence-based policy development for clean growth, we conducted a policy scan at subnational and national levels in Canada supported by targeted scans in other jurisdictions to assess the scope at which cumulative effects are assessed for renewable clean growth projects, and to identify best practices, approaches, and/or methods for assessing the cumulative effects of clean growth. Our policy scan revealed that approaches for assessing cumulative effects of renewable clean growth activities are inadequately developed across Canada. Though we confirmed few existing cumulative effects frameworks in practice, we found a diverse set of cases where cumulative effects have been effectively identified and managed (in Canada and afar) for projects predominately in the natural resource sector. Four policy insights were generated for assessing cumulative effects of renewable clean growth in Canada; (1) adopt a regional approach that considers local context, (2) support the development of valued ecosystem components, (3) conduct rigorous and comprehensive baseline monitoring, and (4) prioritize collaborative governance including with Indigenous governments and communities. Failure to consider cumulative effects during the early phases of renewable clean growth could impede the ability to meet targets and yield the environmental and socio-economic benefits that are promised by the clean growth movement.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose a schema for measuring cumulative effects relative to a safe operating space grounded in ecological resilience. We then explore practical considerations for implementing this schema in CEA based on six attributes of a resilient ecosystem: diversity, connectivity, modularity, memory, openness, and feedbacks. We posit that a safe operating space may serve as a powerful tool to understand how our collective footprint may be undermining the ability of ecosystems to adapt and respond to future disturbances.
