Cereal crop farming in South Africa is critical in supplying staple foods and for generating export revenue. However, intensified farming practices are tied to significant greenhouse gas (GHG) emissions, challenging national climate goals. This study employs the Environmental Kuznets Curve (EKC) hypothesis to analyze time-series data (1961–2021) and identify the cereal yield threshold where emissions begin to decline. The main goal is to find a turning point that balances food security with climate mitigation actions. Employing both parametric and nonparametric techniques, the analysis finds an inverted U-shaped link between cereal yield and emissions, with a turning point at 3.40 tonnes per hectare. The results confirm a nonlinear relationship, with linear and quadratic yield terms statistically significant at the 1 % and 5 % levels, respectively. Above the turning point, higher cereal yields correlate with lower emissions, supporting the feasibility of sustainable intensification strategies. These findings reveal a crucial emissions-reduction benchmark, linking mitigation measures with policy and supporting yield-linked carbon credit schemes to promote sustainable agriculture and lower emissions. The study advances EKC research in agriculture and offers actionable insights for integrating food security with the Nationally Determined Contributions (NDCs). This research contributes to discussions on sustainable development and climate-smart agriculture.
南非的谷类作物种植对于供应主食和创造出口收入至关重要。然而,集约化耕作方式与大量温室气体(GHG)排放有关,对国家气候目标构成挑战。本研究采用环境库兹涅茨曲线(EKC)假设对时间序列数据(1961-2021)进行分析,并确定排放开始下降的谷物产量阈值。主要目标是找到一个转折点,在粮食安全和减缓气候变化行动之间取得平衡。采用参数和非参数技术,分析发现谷物产量和排放量之间呈倒u型关系,转折点为每公顷3.40吨。结果证实了一种非线性关系,线性和二次产量项分别在1%和5%的水平上具有统计学显著性。在拐点以上,较高的谷物产量与较低的排放相关,支持可持续集约化战略的可行性。这些发现揭示了一个关键的减排基准,将缓解措施与政策联系起来,并支持与产量挂钩的碳信用计划,以促进可持续农业和降低排放。该研究推进了EKC在农业领域的研究,并为将粮食安全与国家自主贡献(NDCs)相结合提供了可行的见解。这项研究有助于讨论可持续发展和气候智能型农业。

The Human–Nature Connection (HNC) has gained increasing relevance as a psychological construct linked to environmental behavior, particularly within rapidly urbanizing societies such as Indonesia. Despite growing research interest, variations in measurement models, cultural adaptation, and behavioral relevance remain insufficiently synthesized. This study conducted a systematic review and meta-analysis of 42 eligible empirical studies published between 2010 and November 2025 to evaluate the psychometric performance, structural validity, and behavioral associations of HNC measurement instruments, with a particular emphasis on their adaptation in Indonesia. Searches were performed across Scopus, Web of Science, PubMed, PsycINFO, and regional repositories using PRISMA-based screening criteria. Reliability statistics demonstrated strong measurement stability across instruments, with Cronbach's Alpha ranging from 0.84 to 0.90 and Composite Reliability from 0.86 to 0.92. Exploratory Factor Analysis revealed a four-factor structure, explaining 57.6 % of the variance, with the affective and cognitive dimensions contributing the highest loadings. Meta-analytic modeling yielded a pooled correlation of r = 0.42 between HNC and pro-environmental behavior, with subgroup results indicating the most potent effects among children and young adults (r = 0.45–0.48) and among individuals with at least 120 min of weekly nature exposure. The findings suggest that HNC serves as both a measurable psychological construct and a meaningful behavioral predictor in educational and sustainability contexts. Overall, this review underscores the importance of culturally grounded measurement and highlights opportunities to integrate HNC into environmental education, policy design, and longitudinal intervention research, thereby strengthening ecological engagement across Indonesian society.
人与自然的联系(HNC)作为一种与环境行为相关的心理结构,尤其是在印度尼西亚等快速城市化的社会中,已经获得了越来越多的相关性。尽管研究兴趣不断增长,但测量模型、文化适应和行为相关性的变化仍然没有得到充分的综合。本研究对2010年至2025年11月发表的42项符合条件的实证研究进行了系统回顾和荟萃分析,以评估HNC测量工具的心理测量性能、结构效度和行为关联,并特别强调了它们在印度尼西亚的适应性。使用基于prisma的筛选标准,在Scopus、Web of Science、PubMed、PsycINFO和区域存储库中进行搜索。可靠性统计表明,不同仪器的测量具有很强的稳定性,Cronbach's Alpha在0.84至0.90之间,复合信度在0.86至0.92之间。探索性因子分析揭示了一个四因素结构,解释了57.6%的方差,其中情感和认知维度贡献了最高的负荷。荟萃分析模型显示,HNC与亲环境行为之间的相关性为r = 0.42,亚组结果表明,儿童和年轻人(r = 0.45-0.48)以及每周接触自然至少120分钟的个体的影响最大。研究结果表明,在教育和可持续性背景下,HNC既是一种可测量的心理结构,也是一种有意义的行为预测因子。总体而言,本综述强调了基于文化的测量的重要性,并强调了将HNC整合到环境教育、政策设计和纵向干预研究中的机会,从而加强了印度尼西亚社会的生态参与。

Climate change has intensified the occurrence of natural hazards, leading to widespread forced relocations across the globe. These events have significantly reshaped socio-economic and livelihood pathways in both rural and urban landscapes. This study explores the gendered impacts of climate-induced migration and how women cope with and navigate these challenges in Muhokya resettlement village, Rwenzori region of western Uganda. A cross-sectional research design comprising of a survey of 171 households, 4 focus group discussions, and 20 key informant interviews was used. Quantitative data were analyzed using frequencies and one-sample t-test, while thematic and content analysis were applied to qualitative data. The findings reveal that most women were forcibly displaced after losing their homes to floods. The consequences of displacement have been severe, including increased school dropout rates among girls, early marriages, heightened vulnerability to HIV/AIDS, engagement in transactional sex, denial of conjugal rights, and rising cases of gender-based violence. Limited access to healthcare services, particularly antenatal, sexual, and reproductive health care has further exacerbated women's vulnerability. The coping mechanisms, such as survival-based practices like “sex for fish,” have proven unsustainable and harmful. The study proposes strengthening local women-led self-help groups to enhance access to livelihood assets, integrating gender-responsive livelihood training within resettlement programs, increasing access to government livelihood initiatives, and improving healthcare and psychosocial support services. Establishing inclusive community decision-making platforms can also enhance women's agency in adaptation planning. These interventions offer practical pathways for reducing gender disparities and promoting equitable resilience in line with Sustainable Development Goals 11 and 13.
气候变化加剧了自然灾害的发生,导致全球范围内广泛的被迫搬迁。这些事件极大地重塑了农村和城市景观的社会经济和生计途径。本研究探讨了气候导致的移民对性别的影响,以及乌干达西部鲁文佐里地区Muhokya安置村的妇女如何应对和应对这些挑战。采用横断面研究设计,包括对171个家庭的调查、4个焦点小组讨论和20个关键信息者访谈。定量数据采用频率分析和单样本t检验,定性数据采用主题分析和内容分析。调查结果显示,大多数妇女在洪水中失去家园后被迫流离失所。流离失所的后果非常严重,包括女童辍学率上升、早婚、更容易感染艾滋病毒/艾滋病、从事交易性行为、剥夺夫妻权利以及性别暴力案件增多。获得保健服务,特别是产前保健、性保健和生殖保健的机会有限,进一步加剧了妇女的脆弱性。应对机制,如以生存为基础的做法,如“为鱼做爱”,已被证明是不可持续和有害的。该研究建议加强当地妇女领导的自助团体,以增加获得生计资产的机会,在重新安置方案中纳入促进性别平等的生计培训,增加获得政府生计倡议的机会,并改善医疗保健和社会心理支持服务。建立包容性社区决策平台也可以增强妇女在适应规划中的能动性。这些干预措施为根据可持续发展目标11和13减少性别差异和促进公平抵御力提供了切实可行的途径。

Responses to risk have been insufficiently incorporated into sustainable development pathways. Development interventions can both generate new socio-ecological risks and fail to mitigate the risks experienced by rural communities. We analyse perceptions of socio-ecological risks within community forest user group households in Bagmati province in central Nepal across a three-year period. Community forestry has successfully returned the forest to the middle hills of Nepal, helping to mitigate landslide risks and conserve biodiversity, but other risks are being produced and reinforced within the forest as it transitions. Households are becoming less active in community forest management and are accessing smaller percentages of their income from agriculture and forestry. At the same time, wild animal and wildfire risks are increasing. Climate change is seen to be a key driver of a range of new risks in association with the forest. Perceived household food self-sufficiency has declined recently within all municipalities, with increasingly high levels of households going into debt to support food security. People are valuing the forest for the ecosystem services they provide, including improving biodiversity, supporting subsistence agriculture and stabilising landscapes, but most respondents were not using the forest either to mitigate food insecurity or generate financial incomes. Forests must be managed to continue to be part of the solution, not the problem. As new levels of risk become apparent, knowledge of risk perceptions and interactions with the forest need to be integrated reflexively within policy and practice to guide sustainable development outcomes.
对风险的反应没有充分纳入可持续发展途径。发展干预措施既可能产生新的社会生态风险,也无法减轻农村社区面临的风险。我们分析了尼泊尔中部巴格马蒂省社区森林用户群体家庭在三年期间对社会生态风险的看法。社区林业成功地将森林恢复到尼泊尔的中部山区,帮助减轻了山体滑坡的风险,保护了生物多样性,但随着森林的过渡,其他风险正在产生并加剧。家庭在社区森林管理中的活跃程度越来越低,农业和林业收入所占比例也越来越小。与此同时,野生动物和野火的风险也在增加。气候变化被视为与森林有关的一系列新风险的关键驱动因素。最近,所有城市的家庭粮食自给率都有所下降,越来越多的家庭为支持粮食安全而负债。人们重视森林提供的生态系统服务,包括改善生物多样性、支持自给农业和稳定景观,但大多数受访者既没有利用森林缓解粮食不安全,也没有利用森林创造经济收入。必须对森林进行管理,使其继续成为解决方案的一部分,而不是问题本身。随着新的风险水平变得明显,需要将对风险的认识和与森林的相互作用的知识反射性地纳入政策和实践,以指导可持续发展成果。

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。

Background

Bhubaneswar, a rapidly developing smart city in eastern India, faces persistent air quality challenges primarily due to vehicular emissions, construction, and industrial activities. Conventional monitoring in the city has been limited to a few fixed stations, providing insufficient spatial coverage to represent citywide pollution variability.

Methodology

To address this gap, a dense low-cost sensor (LCS) network comprising 21 stations was deployed across Bhubaneswar's residential, traffic, and industrial zones. The network operated continuously for one year (2022–2023), and the LCS-based PM2.5 and PM10 data were validated against co-located gravimetric reference measurements and compared with MERRA-2 reanalysis datasets to assess performance and spatial representativeness.

Major findings

The LCS-based PM2.5 measurements showed strong agreement with reference gravimetric data (r ∼ 0.92), confirming the reliability of the network for long-term urban monitoring. The observed PM2.5/PM10 ratio (∼0.92) indicated a dominant contribution from fine anthropogenic particles. The network identified pollution hotspots near major highways and dense traffic corridors, where pollutant concentrations exceeded the National Ambient Air Quality Standards (NAAQS) for more than 50 % of the observation period. A notable positive weekend effect was observed across most stations, in contrast to trends reported for other Tier-II Indian cities.

Conclusions

This study provides the first high-resolution, yearlong characterization of PM pollution in Bhubaneswar using a citywide LCS network. The results highlight the potential of low-cost sensing systems for cost-effective, scalable urban air-quality surveillance and support the formulation of targeted mitigation strategies for rapidly urbanizing regions in the Global South.
印度东部快速发展的智慧城市布巴内斯瓦尔面临着持续的空气质量挑战,主要是由于车辆排放、建筑和工业活动。城市的传统监测仅限于几个固定站点,无法提供足够的空间覆盖来反映全市的污染变化。为了解决这一差距,在布巴内斯瓦尔的住宅区、交通和工业区部署了一个由21个站点组成的密集低成本传感器(LCS)网络。该网络连续运行了一年(2022-2023),基于lcs的PM2.5和PM10数据与同一位置的重力参考测量数据进行了验证,并与MERRA-2再分析数据集进行了比较,以评估性能和空间代表性。主要发现:基于lcs的PM2.5测量结果与参考重力数据非常吻合(r ~ 0.92),证实了该网络长期城市监测的可靠性。观测到的PM2.5/PM10比值(~ 0.92)表明细微的人为颗粒占主导地位。该网络确定了主要高速公路和密集交通走廊附近的污染热点,这些地区的污染物浓度超过国家环境空气质量标准(NAAQS)的时间超过50%。与印度其他二线城市的趋势相反,大多数车站都观察到明显的周末效应。本研究利用全市LCS网络,首次提供了布巴内斯瓦尔市全年高分辨率的PM污染特征。研究结果突出了低成本传感系统在具有成本效益、可扩展的城市空气质量监测方面的潜力,并支持为全球南方快速城市化地区制定有针对性的缓解战略。

This article addresses the management of socially sensitive environmental projects that pose significant risks to human health, society, and the environment. Such projects require a careful balance between the interests of diverse stakeholders, as well as the evaluation of complex environmental, health, and economic impacts. We propose a unique systems engineering (SE) framework that integrates both established and innovative methods to improve project management, mitigate risks, and facilitate informed decision-making.
The methodology involves an interdisciplinary analysis of two actual case studies in Israel: the removal of friable asbestos from a school in Haifa and the proposed establishment of a phosphate mine in Sde Barir, near the city of Arad. Employing the systems thinking (ST) approach, the study integrates both conceptual and technical perspectives. ST provides an overarching worldview for understanding interdependencies, feedback loops, and social dynamics, while SE contributes structured processes, analytical rigor, and lifecycle management methods.
The study integrates a tailored combination of engineering and decision-support tools – including, but not limited to, After Action Review (AAR), the Systems Theoretic Accident Model and Processes (STAMP), and Value-Oriented Requirements Analysis (VORA) – to construct a comprehensive framework for managing complex environmental risks and addressing diverse stakeholder concerns. The primary research question is: How can systems engineering frameworks and tools improve the management of socially sensitive environmental projects?
The framework evolved through two carefully selected case studies, each providing an in-depth examination of complex, socially sensitive environmental projects. These cases demonstrate the framework's potential and its capacity to be further strengthened through future applications in additional contexts. The findings indicate that integrating ST with a coordinated set of SE tools significantly improves the balance between competing objectives and enhances decision-making processes. This combined approach promotes a more holistic understanding of project dynamics, enabling better management of environmental, technical, and social dimensions within socially sensitive projects.
本文讨论了对人类健康、社会和环境构成重大风险的社会敏感环境项目的管理。这类项目需要在不同利益攸关方的利益之间谨慎平衡,并对复杂的环境、健康和经济影响进行评估。我们提出了一个独特的系统工程(SE)框架,该框架集成了已建立的和创新的方法,以改善项目管理,减轻风险,并促进知情决策。该方法涉及对以色列的两个实际案例研究进行跨学科分析:从海法的一所学校拆除易碎石棉和拟议在阿拉德市附近的Sde Barir建立磷矿。采用系统思维(ST)的方法,该研究整合了概念和技术的观点。ST为理解相互依赖、反馈循环和社会动态提供了一个总体的世界观,而SE则提供了结构化的过程、分析的严密性和生命周期管理方法。该研究整合了工程和决策支持工具的定制组合,包括但不限于行动后审查(AAR)、系统理论事故模型和过程(STAMP)以及价值导向需求分析(VORA),以构建一个全面的框架,用于管理复杂的环境风险和解决不同利益相关者的关注。主要的研究问题是:系统工程框架和工具如何改善社会敏感环境项目的管理?该框架是通过两个精心挑选的案例研究演变而来的,每个案例都对复杂的、具有社会敏感性的环境项目进行了深入研究。这些案例表明了该框架的潜力及其通过今后在其他情况下的应用而得到进一步加强的能力。研究结果表明,整合科技与一套协调的科技工具显著改善了竞争目标之间的平衡,并增强了决策过程。这种结合的方法促进了对项目动态的更全面的理解,从而在社会敏感项目中更好地管理环境、技术和社会层面。

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. Overall, this paper offers an improved understanding of the complex environmental and socio-economic challenges in the Sundarbans by bringing together two decades of research. The insights can help guide local conservation efforts, as well as global conversations on climate justice, delta sustainability, and resilience in vulnerable ecosystems.
孙德尔本斯是地球上最大的连续红树林,也是联合国教科文组织的世界遗产,它正受到人类活动和气候变化日益严重的威胁。在过去的二十年里,该地区面临着海平面上升、盐度增加、生物多样性丧失、更频繁的气旋、森林砍伐和规划不周的发展。这些问题正在影响生态系统,也使当地社区的生活更加艰难。尽管研究人员对该领域进行了广泛的研究,但仍然缺乏将研究趋势和关键知识领域结合起来的统一分析。本研究旨在通过对2000年至2024年的研究进行系统回顾和文献计量分析来填补这一空白。它探讨了人类和气候相关的压力是如何相互作用并影响孙德尔本斯的环境和居民的,同时也在寻找支持长期可持续性的方法。在这里,我们遵循PRISMA的指导方针,使用VOSviewer、Bibliometrix(基于R语言)和内容分析等工具,从Web of Science数据库中筛选出同行评议的文章(n = 269)。研究结果表明,这方面的工作越来越多,但往往是零散的。共同的主题包括气候变化、生态系统服务退化、对灾害的脆弱性、人类迁移和政策方法。有趣的是,跨学科或以社区为重点的解决方案的研究仍然相对较少,尽管它们对可持续成果至关重要。此外,该研究还指出,需要更强有力、更紧密的治理、跨境合作以及更好地利用传统的地方知识来提高适应性。它还强调了包容性的基层规划和明智政策的重要性,这些政策既要保护生物多样性,又要促进公平和公正。总的来说,本文通过汇集二十年的研究,对孙德尔本斯地区复杂的环境和社会经济挑战有了更好的理解。这些见解可以帮助指导当地的保护工作,以及关于气候正义、三角洲可持续性和脆弱生态系统恢复力的全球对话。

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。

Mining is a significant driver of economic development in developing countries, fueling industrialization, employment, and infrastructure growth. Bangladesh, despite its limited geographic size, relies heavily on fossil fuels, with coal as a primary energy source for electricity generation. The Barapukuria Coal Mine, Bangladesh's only operational coal mine, underscores this dependency on coal. However, coal extraction is associated with substantial carbon emissions and environmental degradation. This review synthesizes current knowledge on the environmental impacts of coal mining in Bangladesh, identifying critical research gaps and addressing key dimensions such as water and stream sediment quality, soil and mine tailings management, and temperature fluctuations with cascading ecological effects. The analysis also examines public health implications, socio-economic impacts, land cover and land use changes, and air quality. The review further explores sustainable mitigation and management strategies to address these challenges. Comparative analyses with global case studies and advanced modeling approaches are recommended to enhance predictive understanding of the long-term environmental impacts of coal mining and to inform effective mitigation planning.
采矿业是发展中国家经济发展的重要推动力,促进了工业化、就业和基础设施的增长。孟加拉国尽管地理面积有限,但严重依赖化石燃料,煤炭是发电的主要能源。巴拉普库里亚煤矿(Barapukuria Coal Mine)是孟加拉国唯一一家运营中的煤矿,突显了该国对煤炭的依赖。然而,煤炭开采伴随着大量的碳排放和环境退化。本综述综合了目前关于孟加拉国煤炭开采对环境影响的知识,确定了关键的研究空白,并解决了水和河流沉积物质量、土壤和矿山尾矿管理以及具有级联生态效应的温度波动等关键方面的问题。该分析还审查了公共卫生影响、社会经济影响、土地覆盖和土地利用变化以及空气质量。本审查进一步探讨了应对这些挑战的可持续缓解和管理战略。建议采用全球案例研究和先进建模方法进行比较分析,以加强对煤炭开采长期环境影响的预测性认识,并为有效的缓解规划提供信息。
