Despite its recognized conservation threat, limited information exists on the bushmeat trade dynamics in sub-Saharan African savannas. This study conducted interviews with 133 illegal hunters and 40 anti-poaching field rangers in Southeastern Zimbabwe, using semi-structured questionnaires. We explored the characteristics, motivations, methods, species targeted, and perceptions of wildlife law enforcement in Save Valley Conservancy (SVC). Overall, illegal bushmeat hunting in SVC is mainly done by less educated and unemployed young to middle aged men (15-40 years old). The motives behind illegal bushmeat hunting mainly included household consumption (96%), the desire to raise income (96%), unemployment (78%), retaliation for wildlife induced losses (62%), culture (29%) and poor benefit sharing (8%). The common hunting methods reported were hunting with dogs (87%), and snaring (65%). Targeted animal species included impala (96%), wildebeest (53%), eland (53%), African buffalo (51%) among other 12 animal species. Illegal bushmeat hunting was generally conducted all year round. The law enforcement penalties were considered less deterrent, and most of the hunters intended to continue with illegal hunting. Measures suggested to minimize illegal bushmeat hunting in the SVC included investing and strengthening wildlife law enforcement, provision of community conservation-based incentives and enhancing environmental education and awareness.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143596033","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}

{"title":"A Review of Hawaii and Plastic Pollution: Potential Innovations within Circular Economy?","authors":"Prisca Ayassamy","doi":"10.1007/s00267-025-02134-0","DOIUrl":"https://doi.org/10.1007/s00267-025-02134-0","url":null,"abstract":"<p><p>The study presents a comprehensive literature review focused on the impacts of plastic pollution within the Hawaiian ocean ecosystem. The analysis is organized into three primary sections to facilitate a structured understanding of the issue. First, the research identifies and categorizes the various types of plastics that contribute to pollution in the marine environment. This includes an exploration of single-use plastics, microplastics, and abandoned fishing gear, among others, each presenting unique challenges to marine ecosystems. Second, the review investigates the multifaceted effects of these plastics on the ocean ecosystem. It examines how plastics, particularly fishing nets and microplastics, have become prevalent elements of marine debris. The literature highlights the intricate ways plastics interact with marine life, including ingestion by various species, entanglement of wildlife, and the introduction of hazardous chemicals that can leach into the ocean. These interactions can lead to significant adverse effects on biodiversity, disrupt food chains, and pose health risks to human populations reliant on marine resources. Third, the paper advocates for the adoption of a circular economy approach as a strategic framework to mitigate the widespread impacts of plastic pollution. It outlines innovative recycling methods, the reduction of plastic production, and the promotion of sustainable alternatives as potential solutions. The findings from the literature review indicate that marine debris, particularly fishing nets, are the most frequently reported items, emphasizing the need for targeted interventions in these areas. Moreover, the study reveals that marine debris often interacts with hazardous chemicals, exacerbating the detrimental effects on both marine biodiversity and human health. Interestingly, it notes that while the presence of plastics can create slicks that might have certain benefits, such as providing microhabitats for some species, these benefits are overshadowed by the overall negative impacts on ecosystems. Additionally, the study discusses the role of wind energy factors in dispersing debris patches identified throughout the Pacific Ocean, illustrating the complex dynamics at play in oceanic pollution. While the paper proposes various sustainable innovations aimed at addressing the plastic crisis, it emphasizes the necessity for further research to thoroughly evaluate the feasibility and resilience of these proposed solutions. This call for more in-depth studies aims to ensure that the strategies developed are both practical and effective in restoring and preserving the Hawaiian ocean ecosystem amidst ongoing challenges posed by plastic pollution.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143596026","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}

Some of the most compelling aspects for public decision making are the inclusion of diverse values in the selection of objectives and the opportunity to create a shared understanding of the system, both the context and potential tradeoffs of different strategies. While the technological requirements of the most rigid SDM processes are out of reach of most public agencies and interested publics, governance structures may enable the use of different stages of SDM to improve decisions, without relying on complete datasets and extensive statistical knowledge. Building upon a 4-year participatory research project, we analyze the use of SDM with four different watershed groups to understand the governance factors that facilitated the use of SDM as a decision support tool. All groups aimed to add human wellbeing objectives to existing natural resource health objectives when making decisions. We found that who defines the objectives and required outputs of planning as well as how decisions were made influenced the extent to which groups completed SDM steps. We also demonstrate that decisions can be improved by engaging in each step of the SDM process, and the perfect decision may not depend on completing all steps.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143596040","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}

While it is widely acknowledged that integrative solutions can bring co-benefits and synergetic outcomes for different sectors, empirical studies that systematically explore cross-sector integration at the operational level are rare. Drawing from two case studies with a high potential for reducing the environmental impacts of energy production and agriculture while restoring nature in the Dutch rural context, this exploratory study aims to provide an improved understanding of the institutional factors that influence the fulfillment of integrative potential in rural areas. To understand how institutional factors influence integrative outcomes, we use the operational level rules that guide actions and interactions among the actors of the Institutional Analysis and Development (IAD) framework. Our analysis shows that the potential of integrative solutions is not fully recognized and realized in Dutch rural areas. Key institutional factors that hamper integration are diverging perceptions of desired outcomes (scope rule), exclusion of important actors from decision-making (position rule), and imbalances in the sharing of costs and benefits (payoff rule). We conclude that agreement on the rules of actions and interactions between the actors is necessary for fulfillment of integrative potential.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571832","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}

This information provided the basis for developing four governance models (Monocentric, Polycentric, Community-based and Networking). Most of the sites presented a dominant governance model, but also incorporated some dimensions of the other models to a lesser degree.

The success of FLR efforts depends on the interests, perceptions, and actions of local communities, extension services, Non-Governmental Organizations, and policymakers. While much research focuses on the direct ecological and economic impacts of FLR, limited attention has been given to how stakeholder perceptions influence the design and implementation of restoration efforts. Understanding these perspectives is crucial for shaping effective policy interventions and ensuring long-term FLR success. This study uses Q methodology to examine stakeholder viewpoints on key considerations and priorities for designing and implementing FLR in Tchamba Prefecture, Togo. The analysis reveals three distinct perspectives: (1) Incentive-Driven Restoration, emphasizing financial incentives and private-sector partnerships as essential for FLR success; (2) Comprehensive and Collaborative Restoration, advocating for an inclusive, multidisciplinary approach that integrates community participation and long-term monitoring; and (3) Incentive-Driven Community Restoration, highlighting the importance of economic incentives in fostering local engagement. Across all perspectives, stakeholders strongly agreed on the importance of biodiversity conservation, stakeholder involvement, and conflict resolution in land use. The findings underscore the need to tailor FLR policies to local contexts and stakeholder preferences, suggesting that flexible, participatory approaches can enhance sustainability and effectiveness.

In this paper, we examine the impact of not only access but also level of use of climate information on adoption intensity of sustainable practices. Based on a large sample data, we used double-hurdle model to account for not only the hurdle farmers need to grapple with to access climate information but also decisions on the actual use (level) of information to probe into the determinants of adoption. Using dose-response function moreover, we consider both access and intensity of use of climate information to estimate the impact on adoption intensity of adaptation and CSA practices. We found the presence of significant differences in the determinants of adoption intensity when accounting for not only access but also actual use of climate information. Specifically, labor endowments such as education and physical labor and sources of information and learning (extension and community groups) were positively correlated with higher adoption. Dose-response function results indicate that intensity of use of climate information increased adoption of CSA practices.

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).
