Recently, urban floods have become more frequent and severe worldwide. It is exacerbated by rapid urbanization, extreme rainfall variations, and inadequate drainage systems. This trend poses significant threats to life, property, and ecosystems. Therefore, it requires widespread adoption of low impact development (LID) strategies. However, this systematic review examines the efficacy, challenges, and prospects of LID approaches in mitigating urban flood hazards intensified by climate change. It synthesizes findings from 96 peer-reviewed studies, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The analysis reveals that LID strategies reduce flood peaks with environmental benefits and sustainable urban development. Quantitative analysis shows LID techniques minimize peak runoff with an average of 42 % (range: 15–75 %) and runoff volume by 34 % (range: 10–75 %) across diverse climatic regions. It demonstrates the efficiency of LID for reducing flood frequency, peaks, and runoff. This review identifies critical knowledge gaps necessitating further LID adaptation and effectiveness research. The implications of the present study emphasize the urgent need for integrated urban planning incorporating LID as a fundamental component of climate resilience strategies. Policymakers and urban designers are inspired to prioritize LID in infrastructure development to enhance flood mitigation efforts and promote sustainable urban environments.

近年来，城市洪水在世界范围内变得越来越频繁和严重。快速城市化、极端降雨变化和排水系统不足加剧了这一问题。这一趋势对生命、财产和生态系统构成了重大威胁。因此，它需要广泛采用低影响发展（LID）战略。然而，这篇系统综述探讨了LID方法在缓解气候变化加剧的城市洪水灾害方面的功效、挑战和前景。它综合了96项同行评议的研究结果，遵循了系统评价和荟萃分析（PRISMA）指南的首选报告项目。分析表明，LID策略降低洪峰具有环境效益和城市可持续发展。定量分析表明，在不同的气候区域，LID技术将峰值径流平均减少42%（范围：15 - 75%），径流量平均减少34%（范围：10 - 75%）。它证明了LID在减少洪水频率、峰值和径流方面的效率。本综述确定了需要进一步开展LID适应和有效性研究的关键知识缺口。本研究的意义强调了综合城市规划的迫切需要，将LID作为气候适应战略的基本组成部分。政策制定者和城市设计师受到启发，在基础设施发展中优先考虑LID，以加强防洪工作，促进可持续的城市环境。

This study examines how climatic and socioeconomic variables influence native vegetation across 108 municipalities along the Araguaia Biodiversity Corridor (ABC), a strategic region in Brazil that connects Amazonian and Cerrado biomes. The corridor was defined as a 40-km-wide buffer along the Tocantins and Araguaia Rivers (20 km each side), based on ecological connectivity principles and supported by federal bill PL 909/2024. We characterized municipalities using land use, climate, and socioeconomic indicators, then modeled native vegetation with a spatial error model to account for spatial dependence. A Socioenvironmental Pressure Index (SPI) was derived to flag municipalities with less or more vegetation than expected after accounting for covariates. Current SPI was also compared with long-term changes (1985–2024) in some predictors. On average, municipalities retained 47 % native vegetation, with variation across the corridor. Land use was the strongest determinant of native vegetation, with larger shares of soybean and pasture associated with less vegetation cover. Higher gross domestic product and population density also correlate with lower vegetation cover. Protected area had a modest positive effect, and climatic predictors had no effect. The SPI flagged five pressure hotspots and two resilience hotspots, and was weakly dependent of long-term change, indicating that it captures deviations from socioeconomic and environmental baselines. Combining spatial econometrics with a residual-based pressure index yields decision-ready evidence at the municipal scale. These results indicate where restoration, regularization, and enforcement should be focused and support place-based policies and federal bill PL 909/2024 to formalize the ABC and align conservation with development.

这项研究考察了气候和社会经济变量是如何影响阿拉瓜亚生物多样性走廊（ABC）沿线108个城市的原生植被的。阿拉瓜亚生物多样性走廊是巴西连接亚马逊和塞拉多生物群落的战略区域。该走廊被定义为沿托坎廷斯河和阿拉瓜亚河（每边20公里）的40公里宽的缓冲区，基于生态连通性原则，并得到联邦法案PL 909/2024的支持。我们使用土地利用、气候和社会经济指标来描述城市特征，然后用空间误差模型对原生植被进行建模，以解释空间依赖性。社会环境压力指数（SPI）在考虑协变量后，用于标记植被比预期少或多的城市。目前的SPI也比较了一些预测指标的长期变化（1985-2024）。平均而言，各市保留了47%的原生植被，在走廊上有所不同。土地利用是原生植被的最强决定因素，大豆和牧草的比例越大，植被覆盖越少。较高的国内生产总值和人口密度也与较低的植被覆盖有关。保护区有一定的积极作用，而气候预测因子没有作用。SPI标记了五个压力热点和两个弹性热点，并且对长期变化的依赖性较弱，表明它捕获了与社会经济和环境基线的偏差。将空间计量经济学与基于残差的压力指数相结合，可以在市政规模上产生决策就绪的证据。这些结果表明，恢复、规范化和执法应该集中在哪里，并支持基于地方的政策和联邦法案PL 909/2024，以使ABC正式化，并使保护与发展保持一致。

Sustainable agriculture depends on effective water management in arid and semi-arid regions facing water scarcity and salinity challenges. This study develops a multi-scale system dynamics model to evaluate the interactions between irrigation policy scenarios and regional economic balances across the Shapour River Basin, comparing infrastructure-oriented, demand management, and hybrid scenarios. The model simulates salinity accumulation and soil-water dynamics at the district level, while capturing basin-wide crop yields, agricultural economics, and water use. Computational results reveal that while demand management alone (scenario 4) outperforms the first three irrigation technology-focused scenarios (scenarios 1–3) with 10 % more enhancements in net economic profit and water economic value and reflects rebound effect of these infrastructure-only policies, the hybrid scenario (scenario 5) that combines both demand management and technology improvement proves most effective, delivering the highest economic returns with 77 % improvements and achieving significant reductions in water use up to 56 % compared to the status quo. These findings showcase the diminishing effectiveness of infrastructure-focused approaches while highlighting the superior performance of the integrated strategies. This demonstrates that the combination of demand management, irrigation technology, and regional economic equity leads to sustainable outcomes. They offer not only actionable guidance for policymakers in the study region, but also a valuable contribution to the global discourse on moving beyond infrastructure-centric approaches in arid and semi-arid agriculture.

可持续农业依赖于干旱和半干旱地区面临缺水和盐度挑战的有效水资源管理。本研究建立了一个多尺度系统动力学模型来评估沙普尔河流域灌溉政策情景与区域经济平衡之间的相互作用，并对基础设施导向、需求管理和混合情景进行了比较。该模型在区域一级模拟盐度积累和土壤-水动态，同时捕获整个流域的作物产量、农业经济和水利用。计算结果表明，虽然单独进行需求管理（情景4）比前三种以灌溉技术为重点的情景（情景1-3）在净经济利润和水经济价值方面的提高高出10%，并反映了这些仅基于基础设施的政策的反弹效应，但将需求管理和技术改进结合起来的混合情景（情景5）被证明是最有效的。与现状相比，提供最高的经济回报，改善了77%，并显著减少了56%的用水量。这些发现表明，以基础设施为重点的方法的有效性正在下降，同时强调了综合战略的卓越表现。这表明需求管理、灌溉技术和区域经济公平相结合可以产生可持续的结果。它们不仅为研究区域的政策制定者提供了可操作的指导，而且还为在干旱和半干旱农业中超越以基础设施为中心的方法的全球论述做出了宝贵贡献。

This study focuses the development of a zero waste center as the flagship project of an initiative to boost sustainable development and in-bound tourism in Kamikatsu, Japan. Undertaking a system-wide impact analysis that was grounded in stakeholder interviews and an assessment of economic data pertaining to the zero waste center and other cascading developments, the case study concludes that the project shows signs of delivering initial modest returns while serving as a promotional beacon for further sustainable development initiatives in the township. However, returns are not promising enough to ensure sustainable revitalization of the town. This will require a more rigorous inflow of economic activity primarily through attracting entrepreneurial investment. Consequently, the paper extends the analysis by introducing a framework to: i) entice entrepreneur interest, ii) encourage business start-ups, iii) boost demand for local products and services, iv) support teething pains associated with the start-up phase, v) enhance business capacity development through workshops and networking events; and vi) develop infrastructure to smooth the settling in process for entrepreneurs.

本研究的重点是在日本上胜町发展零废物中心，作为促进可持续发展和入境旅游的旗舰项目。通过对利益相关者的访谈和对与零浪费中心和其他级联发展相关的经济数据的评估，对整个系统的影响进行了分析，该案例研究得出结论，该项目显示出初步适度回报的迹象，同时为该镇进一步的可持续发展倡议起到了促进作用。然而，回报并不足以保证小镇的可持续振兴。这将需要主要通过吸引企业投资更严格地引进经济活动。因此，本文通过引入一个框架来扩展分析：i)吸引企业家的兴趣，ii)鼓励创业，iii)促进对当地产品和服务的需求，iv)支持与创业阶段相关的磨砺，v)通过研讨会和网络活动加强业务能力发展；六、发展基础设施，使企业家顺利落户。

Land degradation is a pervasive global challenge that undermines ecosystem functions and human well-being, yet evidence remains limited regarding how local communities interpret its drivers, respond to it, and define restoration outcomes. This study assesses these perspectives across twelve community watersheds participating in Ethiopia's national Sustainable Land Management Program—six high-performing “land restoration bright-spots” and six low-performing sites—through semi-structured interviews with 123 key informants and twelve facilitated group discussions. Applying the Driver–Pressure–State–Impact–Response (DPSIR) framework and the Analytic Hierarchy Process (AHP), we assessed how communities interpret degradation drivers and impacts and compared their restoration choices and intended outcomes. The analysis revealed significant differences (P < 0.001): bright-spot communities primarily attributed degradation to socioeconomic and institutional factors, whereas low-performing groups emphasized biophysical causes. Their restoration approaches and desired outcomes also varied: five of the six bright-spots prioritized vegetation regeneration, and all intended to pursue farming-system transformation as their intended outcome, while low-performing communities showed inconsistent priorities and largely aimed to revert to pre-degradation conditions as their outcome. The findings highlight that communities with stronger environmental stewardship orientations are better positioned to adapt to persistent biophysical constraints by addressing human-induced drivers and adopting innovative restoration practices, enabling more transformative and sustainable landscape restoration outcomes.

土地退化是一个普遍存在的全球性挑战，它破坏了生态系统功能和人类福祉，然而，关于当地社区如何解释其驱动因素、如何应对以及如何确定恢复结果的证据仍然有限。本研究通过对123名关键信息提供者的半结构化访谈和12个促进小组讨论，评估了参与埃塞俄比亚国家可持续土地管理计划的12个社区流域（6个表现优异的“土地恢复亮点”和6个表现不佳的地点）的这些观点。应用驱动-压力-状态-影响-响应（DPSIR）框架和层次分析法（AHP），我们评估了群落如何解释退化的驱动因素和影响，并比较了它们的恢复选择和预期结果。分析揭示了显著差异（P < 0.001）：亮点群落主要将退化归因于社会经济和制度因素，而表现不佳的群体则强调生物物理原因。他们的恢复方法和期望结果也各不相同：六个亮点中有五个优先考虑植被再生，并且都打算追求农业系统转型作为他们的预期结果，而表现不佳的社区表现出不一致的优先考虑，并且主要旨在恢复到退化前的状态作为他们的结果。研究结果强调，具有更强环境管理导向的社区能够更好地适应持续的生物物理限制，通过解决人为驱动因素和采用创新的恢复实践，实现更具变革性和可持续性的景观恢复结果。

The synergistic effects of economic growth, development, and a rapidly increasing population have significantly increased the demand for energy and food, leading to greater utilization of resources and environmental consequences. Therefore, policymakers must assess environmental sustainability and its impact on sustainable development. The present study aims to quantify and analyze the environmental carrying capacity of the Fars Province in Iran through the application of a comprehensive fuzzy methodology. The results reveal distinct patterns of environmental and economic capacity across different counties. In Shiraz, the carrying capacity, determined through a combined weighting system, was found to be significantly low, mainly because of the high population pressure and urbanization. Approximately 70 % of the province's land area is characterized by medium to low environmental carrying capacity, particularly in southern and central urban regions. Moreover, a model focusing on the degree of obstacles was applied to examine the relationship between environmental quality and the various factors that influence it. The research outcomes emphasize that the quality of habitats and the level of vegetation coverage are the principal factors that limit the province's carrying capacity, with the frequency of obstacles recorded at over 85 %. This underscores the importance of targeted intervention. Thus, counties in critical conditions should prioritize investments in these aspects to enhance their environmental quality and subsequently move towards developmental efforts.

经济增长、发展和人口迅速增长的协同作用大大增加了对能源和粮食的需求，导致更多地利用资源和环境后果。因此，决策者必须评估环境可持续性及其对可持续发展的影响。本研究旨在运用综合模糊方法，对伊朗法尔斯省的环境承载力进行量化分析。结果表明，不同县域的环境和经济能力存在明显差异。在设拉子，通过联合加权系统确定的承载能力明显较低，主要是由于高人口压力和城市化。该省约70%的土地面积具有中低环境承载力的特点，特别是在南部和中部城市地区。此外，还采用了一个以障碍程度为重点的模型来研究环境质量与影响环境质量的各种因素之间的关系。研究结果强调，生境质量和植被覆盖水平是限制我省承载力的主要因素，障碍物发生的频率在85%以上。这强调了有针对性干预的重要性。因此，处于危急状况的国家应优先考虑在这些方面的投资，以提高其环境质量，并随后转向发展努力。

This study reviews the systemic failures and opportunities in Nigeria's waste management landscape. Nigeria's solid waste crisis reflects structural deficiencies in governance, infrastructure, and behavior, with cascading effects on public health and ecosystems. Using a scoping review methodology guided by Arksey and O’Malley (2005) and reported in line with PRISMA-ScR standards, 84 multidisciplinary studies were synthesized to (i) map institutional and environmental risks, (ii) appraise regional disparities and the role of informal waste pickers, and (iii) evaluate the feasibility of circular economy pathways suited to Nigeria's context. The findings show that fragmented mandates, weak enforcement, and data scarcity entrench open dumping and burning, driving leachate and air-pollution burdens and elevating disease risks, especially in informal settlements. Nonetheless, significant opportunities exist in decentralized organics management, inclusive recycling ecosystems, and targeted waste-to-energy niches. Evidence was translated into a phased governance roadmap that prioritizes a unified national policy with enforceable Extended Producer Responsibility, formal integration of informal workers with safety and finance provisions, city-level digital registries and route optimization, and community-based separation of organics and plastics. While finance, infrastructure gaps, market development, and social acceptance constrain scaling, addressing these challenges can enable a transition from linear disposal to a resilient and circular waste system. Overall, the review concludes that Nigeria's path forward lies in linking governance reform with culturally sensitive, inclusive, and scalable circular economy solutions aligned with SDGs 6, 11, and 12.

本研究回顾了尼日利亚废物管理领域的系统性失败和机遇。尼日利亚的固体废物危机反映了治理、基础设施和行为方面的结构性缺陷，对公共卫生和生态系统产生了连锁效应。使用由Arksey和O’malley（2005）指导并根据PRISMA-ScR标准报告的范围审查方法，综合了84项多学科研究，以(i)绘制制度和环境风险图，（ii）评估区域差异和非正规拾荒者的作用，以及（iii）评估适合尼日利亚背景的循环经济途径的可行性。调查结果表明，分散的授权、薄弱的执法和数据匮乏加剧了露天倾倒和焚烧，加剧了渗滤液和空气污染的负担，并增加了疾病风险，特别是在非正式住区。尽管如此，在分散的有机管理、包容性的回收生态系统和有针对性的废物转化为能源的生态位方面存在着重大机遇。证据被转化为分阶段的治理路线图，该路线图优先考虑统一的国家政策，具有可执行的延伸生产者责任，非正式工人与安全和融资规定的正式整合，城市一级的数字登记和路线优化，以及基于社区的有机和塑料分离。虽然资金、基础设施差距、市场发展和社会接受程度制约了规模的扩大，但解决这些挑战可以实现从线性处置向弹性和循环废物系统的过渡。总体而言，报告的结论是，尼日利亚的前进道路在于将治理改革与符合可持续发展目标6、11和12的具有文化敏感性、包容性和可扩展的循环经济解决方案联系起来。

Arguments based on the ‘land crunch’ phenomenon and its projection to further intensify in the future, thus exacerbating land use demands for food production has prompted calls and at the same time concerns on converting sacred groves (SG) for croplands or plantations. To establish the full benefits of SG beyond its primary intent of providing a religious and cultural heritage-based protected forest, we examined the potential co-benefits of SG. Consequently, the aboveground biomass (AGB), belowground biomass (BGB), amount of carbon, soil physiochemical properties in three land-use systems were empirically measured. Plantation and Cropland with scattered trees (CLST) were used as controls to the SG. The land use systems examined were from three communities in the Guinea Savanna zone of Ghana. The plot technique was used for the vegetation sampling. From the results, it was established that SG recorded the highest AGB, BGB and carbon stock with 620.6 Mg/ha, 161.4 Mg/ha and 391.0 MgC/ha respectively while the carbon stock for CLST was 341.7 MgC/ha and 124.8 MgC/ha for plantation. Similarly, SG had the highest soil carbon stock (81.5 tC/ha), compared to 66.1 tC/ha for plantation and 44.4 tC/ha for CLST. Finally, the paper then presents a decision-outcome framework, highlighting the dual pathways of intended and unintended environmental externalities for the establishment of SG. The paper demonstrates and suggests that the SG do not just deliver religious-based and socio-cultural-based (intended consequence), but they also generate co-benefits outcomes (unintended benefits) through its provision of eco-system services and helping in enhancing climate change mitigation.

基于“土地紧缩”现象及其在未来将进一步加剧的预测的争论，从而加剧了粮食生产的土地使用需求，这引发了呼吁，同时也引发了对将圣林（SG）转化为农田或种植园的担忧。除了提供一个以宗教和文化遗产为基础的保护森林的主要目的外，为了确定SG的全部利益，我们研究了SG的潜在共同利益。在此基础上，对3种土地利用系统的地上生物量（AGB）、地下生物量（BGB）、碳量、土壤理化性质进行了实证研究。以人工林和散林田（CLST）为对照。研究的土地利用系统来自加纳几内亚稀树草原地区的三个社区。植被取样采用样地法。结果表明，SG的AGB、BGB和碳储量最高，分别为620.6 Mg/ha、161.4 Mg/ha和391.0 MgC/ha， CLST的碳储量最高，分别为341.7 Mg/ha和124.8 MgC/ha。同样，SG的土壤碳储量最高（81.5 tC/ha），人工林为66.1 tC/ha， CLST为44.4 tC/ha。最后，本文提出了一个决策结果框架，强调了建立可持续发展的预期和非预期环境外部性的双重途径。该论文论证并建议，SG不仅提供基于宗教和社会文化的（预期结果），而且还通过提供生态系统服务和帮助加强减缓气候变化产生共同效益结果（意外效益）。

This paper aims to assess the effects of the educational level of a country on the climate actions (adaptation and mitigation) that it adopts, and measure the extent to which social inequality, educational quality and access to schooling contribute to such actions. To achieve this aim, the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique was applied to a sample of 195 countries from 18 indicators related to education, income inequality, adaptation and mitigation that exist in global databases. The main results are a) the level of education has a positive effect on adaptation (.824) and mitigation (.927) actions; b) inclusion of the quadratic term for educational level further underscores its central importance in explaining mitigation action (.460); c) Likewise, the quadratic effect of income inequality emerges only as a propensity to mitigate carbon emissions (−.140); d) in absolute values, the difficulty of accessing education has an indirect effect (−.721) that is greater than that of educational quality (.302). These results indicate that, in addition to the need to guarantee education for all, countries also need to reduce their inequalities. Furthermore, developing countries should prioritize actions to include children and young people in climate change education initiatives, so that the indirect effects of climate change adaptation are realized, while reducing inequality can help to foster carbon emissions mitigation efforts. The policy implications of this paper are twofold. First, the paper highlights that improving access to education is more impactful than reducing income inequality for climate adaptation and mitigation. Second, policymakers should prioritize expanding educational opportunities, particularly in vulnerable regions, to enhance climate resilience and sustainable practices. Investments in education can drive long-term climate action more effectively than income redistribution alone.

本文旨在评估一个国家的教育水平对其采取的气候行动（适应和减缓）的影响，并衡量社会不平等、教育质量和受教育机会对此类行动的影响程度。为了实现这一目标，从全球数据库中存在的与教育、收入不平等、适应和缓解有关的18个指标中，对195个国家的样本应用了偏最小二乘结构方程建模（PLS-SEM）技术。主要结果是：a)教育水平对适应（.824）和减缓（.927）行动有积极影响；B)列入教育水平的二次项进一步强调了其在解释缓解行动方面的核心重要性（.460）；c)同样，收入不平等的二次效应仅表现为减少碳排放的倾向（- 0.140）；D)在绝对值上，获得教育的困难的间接影响（- .721）大于教育质量的间接影响（.302）。这些结果表明，除了需要保障全民教育外，各国还需要减少不平等现象。此外，发展中国家应优先采取行动，将儿童和年轻人纳入气候变化教育倡议，以便实现适应气候变化的间接影响，同时减少不平等现象有助于促进减少碳排放的努力。本文的政策含义是双重的。首先，本文强调，在适应和减缓气候变化方面，改善受教育机会比减少收入不平等更有影响力。其次，政策制定者应优先考虑扩大教育机会，特别是在脆弱地区，以增强气候适应能力和可持续实践。教育投资比单纯的收入再分配更能有效地推动长期气候行动。

The rapid growth in global e-waste production presents profound social challenges for developing nations like Ghana, where informal recycling practices remain a major economic activity, albeit being detrimental to the environment and human health. This paper examines the potential of Circular Economy (CE) principles, particularly reduction and reuse, in addressing the social challenges associated with e-waste. Drawing on interviews with key informants, including e-waste workers and government officials, as well as insights from Nigeria's Extended Producer Responsibility (EPR) program, the paper identifies critical lessons and opportunities for improving Ghana's approach to e-waste. The paper reveals that while CE offers environmental benefits, it often neglects the social inequities embedded in informal sectors. We argue that an equitable CE transition in Ghana requires integrating social protections, alternative livelihoods, international cooperation, and environmental reforms.

全球电子废物产量的迅速增长给加纳等发展中国家带来了深刻的社会挑战，在这些国家，非正式的回收做法仍然是一项主要的经济活动，尽管对环境和人类健康有害。本文探讨了循环经济（CE）原则的潜力，特别是减少和再利用，在解决与电子废物相关的社会挑战方面。通过对包括电子废物工人和政府官员在内的关键线人的采访，以及来自尼日利亚扩展生产者责任（EPR）计划的见解，本文确定了改进加纳处理电子废物方法的关键教训和机会。该论文揭示，虽然环保带来了环境效益，但它往往忽视了嵌入非正式部门的社会不平等。我们认为，加纳公平的经济转型需要整合社会保护、替代生计、国际合作和环境改革。
