While the engagement of large corporations in sustainability policy has been widely studied, the potential role of small and medium-sized enterprises (SMEs) in this area remains underexplored. This qualitative study aims to clarify how SMEs can participate in sustainability-related policymaking within the context of political corporate social responsibility (CSR). To that end, interviews were conducted with 14 pioneering Japanese SMEs that had received recognition through one of two government-sponsored award programs for their implementation of the Sustainable Development Goals (SDGs). To analyze the political activities of these firms, this study adopts the framework proposed by Westman et al. (2020), which conceptualizes SME political engagement through formal political participation, activism, civic engagement, and involvement. Based on this framework, the collected data were classified and analyzed to identify how SMEs engage in political processes. The findings reveal that SMEs influence both sustainability policymaking and informal rule-setting within sectors such as production and healthcare, often through participation in advocacy groups and other collective actions. These results suggest that SMEs are not merely passive recipients of policy but have the capacity to shape it through diverse forms of engagement, acting as policy actors. By positioning SMEs as a previously underexamined unit of analysis, the study contributes to the literature on political CSR and sustainability governance, offering a new perspective on the ways in which smaller firms can participate in and help shape public policy, particularly within the sustainability domain.
虽然大公司参与可持续政策的问题已得到广泛研究,但中小型企业在这一领域的潜在作用仍未得到充分探讨。本定性研究旨在阐明中小企业如何在政治企业社会责任(CSR)的背景下参与与可持续发展相关的政策制定。为此,我们采访了14家开创性的日本中小企业,这些企业因实施可持续发展目标(sdg)而获得了两个政府资助的奖励计划之一的认可。为了分析这些企业的政治活动,本研究采用了Westman等人(2020)提出的框架,该框架将中小企业的政治参与概念化为正式的政治参与、行动主义、公民参与和参与。基于这一框架,收集的数据被分类和分析,以确定中小企业如何参与政治进程。研究结果表明,中小企业通常通过参与倡导团体和其他集体行动,影响生产和医疗保健等部门的可持续性政策制定和非正式规则制定。这些结果表明,中小企业不仅是政策的被动接受者,而且有能力通过各种形式的参与,作为政策行动者来塑造政策。通过将中小企业定位为以前未被充分研究的分析单元,该研究为政治企业社会责任和可持续性治理的文献做出了贡献,为小型企业参与和帮助制定公共政策的方式提供了新的视角,特别是在可持续性领域。

Coastal litter remains a significant environmental and public health concern, negatively affecting tourism, marine ecosystems and the livelihoods of coastal communities. Despite ongoing sanitation interventions, many beach-cleaning initiatives in Ghana are externally driven and lack long-term sustainability. This study examined the role of informal women's community groups in maintaining beach cleanliness in Ghana's Greater Accra Region and explored strategies to strengthen their contributions to sustainable, community-driven sanitation. Data were collected using a structured questionnaire administered to 192 respondents, comprising 155 beach users and 37 community residents, alongside ten key informant interviews and eight focus group discussions conducted across nine purposefully selected beaches. Quantitative data were analysed using descriptive statistics (frequencies and percentages) and chi-square tests to examine associations between sociodemographic characteristics, participation in clean-up activities, and perceptions of beach cleanliness. Qualitative data were analysed thematically. The results show that although over 80 % of respondents regarded beach cleanliness as highly important, only approximately one-third had ever participated in organised clean-up activities. Approximately 70 % reported that existing women's groups were not actively involved in beach-cleaning efforts, largely due to limited recognition, inadequate resources, and weak institutional coordination issues. Chi-square analyses indicated that participation in clean-up activities was significantly associated with stronger perceptions of shared responsibility for beach cleanliness, whereas educational level showed a modest association with pro-cleanliness attitudes. Qualitative findings further revealed that women's groups—often organised around religious, trade, and community networks—possess substantial social capital, organisational capacity, and culturally grounded commitments to cleanliness that remain largely underutilised. The study concludes that repositioning informal women's associations through targeted capacity building, material and financial support, and stronger institutional partnerships can enhance sustainable community-led coastal sanitation in Ghana.
沿海垃圾仍然是一个重大的环境和公共卫生问题,对旅游业、海洋生态系统和沿海社区的生计产生负面影响。尽管正在进行卫生干预,但加纳的许多海滩清洁举措是由外部驱动的,缺乏长期可持续性。本研究考察了加纳大阿克拉地区非正式妇女社区团体在保持海滩清洁方面的作用,并探讨了加强其对可持续的、社区驱动的卫生设施的贡献的战略。我们以结构化问卷的方式收集了192名受访者(包括155名泳滩使用者和37名社区居民)的数据,并在9个有目的地选择的泳滩进行了10次重要的信息访谈和8次焦点小组讨论。使用描述性统计(频率和百分比)和卡方检验对定量数据进行分析,以检验社会人口特征、参与清洁活动和对海滩清洁度的看法之间的关联。对定性数据进行专题分析。调查结果显示,虽然超过八成受访者认为泳滩清洁非常重要,但只有约三分之一的受访者曾参与有组织的清洁活动。大约70%的人报告说,现有的妇女团体没有积极参与海滩清洁工作,主要是由于认识有限、资源不足和机构协调薄弱等问题。卡方分析表明,参与清洁活动与更强烈的海滩清洁共同责任观念显著相关,而教育水平与支持清洁态度有适度关联。定性研究结果进一步表明,妇女团体——通常是围绕宗教、贸易和社区网络组织起来的——拥有大量的社会资本、组织能力和基于文化的清洁承诺,但这些承诺在很大程度上仍未得到充分利用。该研究的结论是,通过有针对性的能力建设、物质和财政支持以及更强有力的机构伙伴关系,重新定位非正式妇女协会,可以促进加纳社区主导的可持续沿海卫生。

Economic and environmental prospects of implementation of waste management systems in higher educational institutions (HEIs): A study on IIT Indore campus 高等教育机构实施废物管理系统的经济和环境前景:印度理工学院印多尔校区的研究
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2026-01-25 DOI: 10.1016/j.envdev.2026.101439

Waste management at HEIs presents peculiar challenges as an educational institution operates like a mini municipality. Therefore, this work will discuss the waste management practices at IITIand the quantification of both organic and inorganic waste. Residential hostels, on average, produce 68 kg of waste per day, but married scholar residences exceed this mark, thus demanding suitable and effective management strategies. Advanced time series models, including SARIMA, Prophet, and Holt-Winters, were utilized to predict waste trends; ARIMA was the most accurate of the three (RMSE = 27.24 kg). A techno-economic analysis of the proposed on-site waste treatment facilities revealed that the biogas plant could achieve a payback period of 20 months, with a cumulative cash inflow of INR 3.14 Million (approximately 35,356.18 USD) over three years. Similarly, a Material Recovery Facility (MRF) is expected to break even in four years with a Net Present Value (NPV) of INR 15.18 Million (170,894.28 USD) over a decade. The results indicate that, in HEIs, source segregation, stakeholder engagement, and infrastructure development for integrated waste management systems minimize environmental impacts and are financially viable. The proposed predictive waste management framework will integrate cost-effective treatment options with waste reduction strategies to promote a circular economy. These results can serve as recommendations for policymakers and campus administrators to enhance sustainability in their waste management practices.
作为一个像迷你城市一样运作的教育机构,高等学校的废物管理面临着特殊的挑战。因此,本工作将讨论iit的废物管理实践以及有机和无机废物的量化。宿舍平均每天产生68公斤的垃圾,但已婚学者宿舍超过了这个数字,因此需要适当和有效的管理策略。利用SARIMA、Prophet和Holt-Winters等先进时间序列模型预测废弃物趋势;ARIMA是三者中最准确的(RMSE = 27.24 kg)。对拟议的现场废物处理设施的技术经济分析显示,沼气厂可以实现20个月的投资回收期,三年内累计现金流入为314万印度卢比(约合35,356.18美元)。同样,材料回收设施(MRF)预计在四年内实现收支平衡,十年内净现值(NPV)为1518万印度卢比(170,894.28美元)。结果表明,在高等教育机构中,污染源隔离、利益相关者参与和综合废物管理系统的基础设施发展可以最大限度地减少对环境的影响,并且在财政上是可行的。拟议的预测性废物管理框架将把具有成本效益的处理方案与减少废物战略结合起来,以促进循环经济。这些结果可以作为政策制定者和校园管理人员的建议,以提高其废物管理实践的可持续性。

Cities in developing countries are rapidly urbanizing, often in ways that undermine urban livability. Yet, in Ghana, evidence on geographic disparities in livability conditions remains limited. We developed a comprehensive single-index urban livability (ULI) score based on 18 contextually relevant factors for Greater Kumasi in Ghana. Physical environmental factors were derived from Landsat 8 imagery; particulate matter (PM2.5) was extracted from the Socioeconomic Data and Application Center (SEDAC). All other variables were derived from data obtained from OpenStreetMap. We used principal component analysis (PCA) to weight our variables and a weighted sum function to develop the final models. We then modeled population exposure to unlivable conditions and geographic disparities in the ULI scores. Results indicate that 39.7 % of Greater Kumasi falls within the high to very high livability range, while 40 % is categorized as unlivable. Kumasi Metro ranks highest overall, though it exhibits significant disparities in livability, with an entropy score of 2.67 (SD: 0.32). Social amenities and convenience were the strongest predictors of livability, with R2 values of 85.6 % and 76 %, respectively, while the health sub-model showed weaker correlations (R2 = 14 %). We found pronounced geographic inequalities, especially in access to social services and environmental quality, with central areas enjoying more benefits than the outskirts. Based on the study's findings, we offer recommendations for policymakers and urban planners to address these disparities and enhance urban livability.
发展中国家的城市正在迅速城市化,但城市化的方式往往会破坏城市的宜居性。然而,在加纳,关于宜居条件的地理差异的证据仍然有限。我们基于18个背景相关因素为加纳大库马西开发了一个综合的单指数城市宜居性(ULI)评分。物理环境因子来源于Landsat 8图像;颗粒物(PM2.5)数据来自社会经济数据与应用中心(SEDAC)。所有其他变量均来自OpenStreetMap获得的数据。我们使用主成分分析(PCA)对变量进行加权,并使用加权和函数来开发最终模型。然后,我们在ULI得分中模拟了人口暴露于不适宜居住条件和地理差异的情况。结果表明,39.7%的大库马西地区属于高至非常高宜居范围,而40%的地区被归类为不适宜居住。库马西地铁在总体上排名最高,但在宜居性方面存在显著差异,熵值为2.67 (SD: 0.32)。社会便利和便利是宜居性的最强预测因子,R2值分别为85.6%和76%,而健康子模型的相关性较弱(R2 = 14%)。我们发现明显的地域不平等,特别是在获得社会服务和环境质量方面,中心地区比郊区享受更多的福利。根据研究结果,我们为政策制定者和城市规划者提供建议,以解决这些差异并提高城市宜居性。

A meta-analysis of waste sorting behavior: Examining the Theory of Planned Behavior (TPB) and the role of contextual factors 垃圾分类行为的元分析:计划行为理论与情境因素作用的检验
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2026-01-02 DOI: 10.1016/j.envdev.2025.101426

Although waste sorting has been widely recognized as a key aspect of solid waste management and extensively studied using the TPB, previous empirical findings remain varied and inconsistent, particularly regarding the relationships among TPB variables, which limits the formulation of constructive insights for stakeholders and policymakers. This article aims to quantitatively synthesize the relationships among the core constructs of the TPB in relation to waste sorting behavior and to examine whether income level and continent moderate these relationships. A meta-analysis was conducted to identify and statistically integrate 39 empirical studies comprising 26,001 respondents, all of which were related to waste sorting intention and behavior. These studies were retrieved from two reputable databases, namely Scopus and Web of Science (WoS), and were evaluated using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The results of the analysis indicate that the TPB effectively explains both the intention (INT) and behavior (BHV) associated with waste sorting. Attitude toward the behavior (ATB), subjective norm (SN), and perceived behavioral control (PBC) all exhibit a positive and significant influence on waste sorting intention. Intention is also found to be a significant predictor of actual behavior. However, the analysis of moderating variables reveals that the core constructs of TPB are significantly related only in upper-middle income countries and in Asia. This study successfully synthesizes and statistically integrates the factors influencing waste sorting intention and behavior, thereby providing greater clarity regarding the core constructs of the TPB in this context. This study also demonstrates the influence of contextual factors, namely income level and continent, highlighting the need for waste sorting policies to consider the unique characteristics of each location.
尽管废物分类已被广泛认为是固体废物管理的一个关键方面,并使用TPB进行了广泛的研究,但先前的实证研究结果仍然存在差异和不一致,特别是关于TPB变量之间的关系,这限制了利益相关者和政策制定者的建设性见解的形成。本文旨在定量地综合城市垃圾分类的核心结构与垃圾分类行为之间的关系,并考察收入水平和大陆是否调节了这些关系。通过荟萃分析,对39项涉及26001名受访者的与垃圾分类意愿和行为相关的实证研究进行识别和统计整合。这些研究从两个著名的数据库,即Scopus和Web of Science (WoS)中检索,并使用系统评价和荟萃分析首选报告项目(PRISMA)协议进行评估。分析结果表明,城市规划有效地解释了与垃圾分类相关的意图(INT)和行为(BHV)。行为态度(ATB)、主观规范(SN)和感知行为控制(PBC)对垃圾分类意愿均有显著正向影响。意向也被发现是实际行为的重要预测因子。然而,对调节变量的分析表明,TPB的核心结构仅在中高收入国家和亚洲显著相关。本研究成功地综合并统计整合了影响垃圾分类意愿和行为的因素,从而更清楚地了解了在这种背景下城市垃圾处理中心的核心构建。本研究还显示了环境因素的影响,即收入水平和大洲,突出了废物分类政策需要考虑每个地点的独特特征。

Unraveling anthropogenic and climate stressors in the Sundarbans and their ripple effects on livelihoods and ecosystems, and adaptation strategies for a sustainable future – A systematic review 揭示孙德尔本斯地区的人为和气候压力源及其对生计和生态系统的连锁反应,以及可持续未来的适应战略——系统综述

The Sundarbans, the largest continuous mangrove forest on Earth and a UNESCO World Heritage Site, is under growing threat from human activity and climate change. Over the last two decades, the region has faced rising sea levels, increasing salinity, biodiversity loss, more frequent cyclones, deforestation, and poorly planned development. These issues are affecting the ecosystem and also making life harder for local communities. Although researchers have studied the area extensively, there is still a lack of a unified analysis that brings together research trends and key knowledge areas. This study aims to fill that gap by offering a systematic review followed by a bibliometric analysis of studies from 2000 to 2024. It explores how human and climate-related pressures interact and affect both the environment and people living in the Sundarbans, while also looking for ways to support long-term sustainability. Here, we followed PRISMA guidelines and used tools like VOSviewer, Bibliometrix (based on R), and content analysis to review peer-reviewed articles (n = 269), screened out from the Web of Science database. Findings indicate a growing body of work, but one that is often fragmented. Common themes included climate change, degradation of ecosystem services, vulnerability to disasters, human migration, and policy approaches. Interestingly, studies that cross disciplines or focus on community-based solutions are still relatively rare, even though they are essential for sustainable outcomes. The study, further, points to the need for stronger, more connected governance, cooperation across borders, and better use of traditional local knowledge to improve adaptability. It also stresses the importance of inclusive, grassroots planning and smart policies that protect biodiversity while also promoting fairness and equity.

Agri-Environmental Schemes (AES) are a key policy tool within the European Union's Common Agricultural Policy (CAP) aimed at promoting sustainable farming practices and mitigating environmental externalities. However, their effectiveness in reducing input use in high-value, resource-intensive sectors such as viticulture remains uncertain. This study evaluates the impact of AES participation on input expenditures in Hungary's wine sector, focusing on fertilizer use, crop protection costs, and energy consumption. Using a robust econometric approach - Propensity Score Matching (PSM), Entropy Balancing (EB), and Inverse Probability Weighting (IPW) - the analysis addresses selection bias and estimates the causal effects of AES participation. Findings indicate that AES participation significantly reduces crop protection costs, suggesting a shift towards more sustainable pest management practices. However, no significant effects are observed on fertilizer or energy expenditures, highlighting potential gaps in AES design concerning these critical inputs. Additionally, results suggest that AES participants manage larger, resource-abundant farms, raising concerns about the inclusivity of the scheme. These findings underscore the need for targeted policy refinements to enhance the effectiveness of AES in viticulture, particularly by improving accessibility for smaller farms and strengthening incentives for input reduction. The study contributes to the broader discourse on agri-environmental policy by providing empirical evidence to inform the design of more effective and inclusive sustainability interventions in the European wine sector.
农业环境计划(AES)是欧盟共同农业政策(CAP)中的一项关键政策工具,旨在促进可持续农业实践和减轻环境外部性。然而,它们在减少高价值资源密集型部门(如葡萄栽培)投入使用方面的有效性仍不确定。本研究评估了AES参与对匈牙利葡萄酒行业投入支出的影响,重点关注化肥使用、作物保护成本和能源消耗。使用稳健的计量经济学方法-倾向得分匹配(PSM),熵平衡(EB)和逆概率加权(IPW) -分析解决了选择偏差并估计了AES参与的因果效应。研究结果表明,AES的参与显著降低了作物保护成本,表明向更可持续的病虫害管理做法转变。然而,没有观察到对肥料或能源支出的显著影响,突出了AES设计在这些关键投入方面的潜在差距。此外,结果表明,AES参与者管理着更大、资源丰富的农场,这引起了人们对该计划包容性的担忧。这些发现强调需要有针对性地完善政策,以提高AES在葡萄栽培中的有效性,特别是通过改善小型农场的可及性和加强减少投入的激励措施。该研究通过提供经验证据,为欧洲葡萄酒行业更有效和更具包容性的可持续性干预措施的设计提供信息,从而有助于更广泛地讨论农业环境政策。

Stuck between strategy and practice: Why ESG fails to take root in tunisian firms 战略与实践之间的困境:为什么ESG未能在突尼斯公司扎根
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2025-12-25 DOI: 10.1016/j.envdev.2025.101418

In many emerging economies, ESG commitments remain largely symbolic, signaling alignment with global sustainability norms without transforming organizational practices. This study examines how this dynamic unfolds in Tunisia, where voluntary ESG reporting guidelines introduced in 2021 created early regulatory momentum but lacked effective enforcement. Drawing on 18 semi-structured interviews and internal documents from six publicly listed firms across diverse sectors, the study explores how mid-level ESG implementers navigate ambiguous mandates and weak organizational infrastructures.
An integrated framework combining implementation theory, institutional decoupling, and role conflict theory is used to explain how symbolic board-level commitments (macro) produce organizational fragmentation (meso) and role ambiguity (micro) sustaining a cycle of symbolic adoption.
Four mechanisms are identified: symbolic board compliance, unclear ESG roles, fragmented interdepartmental coordination, and leadership ambivalence reinforced by cultural resistance. Sectoral differences reveal that banks exhibit more sophisticated reporting but remain largely symbolic in practice, while manufacturing and retail firms engage minimally.
The study highlights policy levers—such as stronger enforcement, targeted ESG literacy initiatives, and empowered mid-level actors—that can shift ESG from reputational signaling to operational integration.
在许多新兴经济体,ESG承诺在很大程度上仍然是象征性的,表明与全球可持续发展规范保持一致,而没有改变组织实践。本研究考察了这一动态如何在突尼斯展开,该国于2021年推出的自愿ESG报告准则创造了早期的监管势头,但缺乏有效的执行。通过18次半结构化访谈和来自不同行业的6家上市公司的内部文件,本研究探讨了中层ESG实施者如何应对模棱两可的授权和薄弱的组织基础设施。本文采用了一个整合了执行理论、制度解耦理论和角色冲突理论的框架来解释象征性董事会层面的承诺(宏观)如何产生组织碎片化(中观)和角色模糊(微观),从而维持象征性采用的循环。研究确定了四种机制:象征性的董事会合规、不明确的ESG角色、支离破碎的部门间协调,以及因文化阻力而强化的领导矛盾心理。行业差异表明,银行表现出更复杂的报告,但在实践中基本上仍是象征性的,而制造业和零售企业参与的程度最低。该研究强调了政策杠杆——例如更强有力的执法、有针对性的ESG扫盲计划和赋权中层行为者——可以将ESG从声誉信号转变为业务整合。

This study aims to evaluate the spatiotemporal impacts of climate-induced drought on crop production across the USA from 2003 to 2023, with a focus on understanding how different climatic factors influence agricultural yield in drought-prone regions. This study exclusively considered climatic factors, including precipitation, temperature, and drought severity, with no anthropogenic influences. To understand the different aspects of drought, four drought indices were selected: Standardized Precipitation Index (SPI) for short-term precipitation anomalies; Standardized Precipitation Evapotranspiration Index (SPEI) for temperature-adjusted drought; Evaporative Demand Drought Index (EDDI) for atmospheric demand; and Palmer Drought Severity Index (PDSI) for long-term drought conditions. These indices were quantified using Google Earth Engine, providing a consistent and large-scale geospatial dataset. Factors such as surface temperature and precipitation distributions were also investigated. Investigating surface temperature and precipitation helps explain their direct role in driving drought variability and crop yield changes, thereby strengthening the study's objective of assessing climate-induced impacts on agriculture. The results revealed an increase in drought-prone and wet-attributed areas along with expanded croplands (corn, cotton, soybeans, wheat, and rye) during study period. Surface temperatures have increased across the southwestern regions, while precipitation rates have increased across the eastern regions. Further, using Shapley Additive Explanations (SHAP) algorithms, the climate-induced drought impacts on crop yield were investigated more in consideration of the magnitudes of factors, which suggests that the impacts of drought and climatic factors varied in different years, while precipitation had the highest impact on crop fields in almost every phase. Furthermore, spatiotemporal trend analysis and classification of precipitation regimes were conducted using Google Earth Engine to detect shifting patterns over the past two decades. The impact of precipitation on crop yield has intensified over time, particularly in regions with declining rainfall. It also shows how the precipitation impact changed from high precipitation to low precipitation over the last 20 years using geospatial analysis. The study also characterized drought events based on their frequency, duration, intensity, and spatial extent across different U.S. regions. Findings revealed an increase in the occurrence and severity of moderate to extreme droughts, especially in the western and central parts of the country. Overall study demonstrates the significant impacts of climate-induced drought on crop production as well as food security across the USA, highlighting the need for targeted water management and adaptive agriculture practices.
本研究旨在评估2003 - 2023年气候干旱对美国作物生产的时空影响,重点了解不同气候因素对干旱易发地区农业产量的影响。本研究专门考虑了气候因素,包括降水、温度和干旱严重程度,没有人为影响。为了了解干旱的不同方面,选择了4个干旱指数:用于短期降水异常的标准化降水指数(SPI);温度调整干旱的标准化降水蒸散发指数(SPEI)大气需求的蒸发需求干旱指数(EDDI)帕尔默干旱严重指数(PDSI)用于长期干旱条件。利用谷歌Earth Engine对这些指标进行量化,提供了一致的大尺度地理空间数据集。研究了地表温度和降水分布等因素。调查地表温度和降水有助于解释它们在驱动干旱变异性和作物产量变化方面的直接作用,从而加强了评估气候对农业影响的研究目标。结果显示,在研究期间,随着农田(玉米、棉花、大豆、小麦和黑麦)的扩大,干旱易发和湿润地区增加。西南地区的地表温度上升,而东部地区的降水率上升。此外,利用Shapley加性解释(Shapley Additive Explanations, SHAP)算法对气候干旱对作物产量的影响进行了更多的研究,考虑了各因子的大小,结果表明,干旱和气候因子的影响在不同年份有所不同,而降水对作物产量的影响几乎在每个阶段都是最大的。在此基础上,利用谷歌Earth Engine对近20年降水进行了时空趋势分析和分类。随着时间的推移,降水对作物产量的影响越来越大,特别是在降雨量减少的地区。利用地理空间分析显示了近20年降水影响由高降水到低降水的变化过程。该研究还根据美国不同地区干旱事件的频率、持续时间、强度和空间范围来描述干旱事件。调查结果显示,中度至极端干旱的发生和严重程度有所增加,特别是在该国的西部和中部地区。总体研究表明,气候引起的干旱对美国各地的作物生产和粮食安全产生了重大影响,强调了有针对性的水资源管理和适应性农业实践的必要性。

Evaluating public policy effectiveness in reducing wildfires in Brazil 评估巴西减少野火的公共政策有效性
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2025-12-05 DOI: 10.1016/j.envdev.2025.101413

Wildfires in Brazil have intensified over the past two decades, posing escalating threats to biodiversity, public health, and climate stability. In response, the Brazilian government has enacted several public policy interventions aimed at curbing wildfire incidence. This study evaluates the causal impact of two major federal interventions—the PPCerrado Plan (2010) and the Forest Code reform (Law No 12.651/2012)—on national wildfire activity between 2003 and 2017. Using Bayesian structural time-series models, we estimated counterfactual wildfire trends in the absence of policy interventions and compared these to observed records, adjusting for key climatic variables and temporal confounders. Results reveal that both policies produced statistically significant reductions in wildfire activity, particularly during peak fire months such as August. The PPCerrado Plan was associated with an average monthly reduction of 5120 wildfires (−54.2 %) during effective periods, while the Forest Code yielded an average reduction of 28,880 wildfires per month (−73.1 %) across selected months. However, these effects were temporally limited and not consistently sustained across all post-intervention years. Our findings suggest that while policy frameworks can mitigate wildfire risks, their long-term success is contingent on effective implementation, cross-scale coordination, and alignment with local socioeconomic realities. We conclude that integrating legal enforcement with economic incentives, institutional capacity-building, and culturally adaptive fire management is essential to achieving durable reductions in wildfire activity in Brazil.
过去二十年来,巴西的野火愈演愈烈,对生物多样性、公众健康和气候稳定构成了日益严重的威胁。作为回应,巴西政府制定了几项旨在控制野火发生率的公共政策干预措施。本研究评估了2003年至2017年期间两项主要联邦干预措施——PPCerrado计划(2010年)和森林法改革(第12.651/2012号法律)对国家野火活动的因果影响。利用贝叶斯结构时间序列模型,我们在没有政策干预的情况下估计了反事实的野火趋势,并将其与观测记录进行了比较,调整了关键的气候变量和时间混杂因素。结果显示,这两项政策在统计上都显著减少了野火活动,特别是在8月等火灾高峰期。PPCerrado计划在有效期内平均每月减少5120起野火(- 54.2%),而《森林法》在选定月份平均每月减少28,880起野火(- 73.1%)。然而,这些影响是暂时有限的,并不是在干预后的所有年份都持续存在。我们的研究结果表明,虽然政策框架可以减轻野火风险,但其长期成功取决于有效实施、跨规模协调以及与当地社会经济现实的一致性。我们的结论是,将执法与经济激励、机构能力建设和文化适应性火灾管理相结合,对于实现巴西野火活动的持久减少至关重要。
