Throughout the “Age of Aid” (1944–1989)4 development has been seen as essentially economic in nature. Increasingly, however, it has become apparent that it is economic only in its consequences. It is something else - entitlements, democratization … social capital - that makes development possible. A different paradigm is therefore needed, and we begin by sketching that by way of the various “experiments” - nationalization, privatization and communitization - with Nepal's forests over the past half-century. Nationalization and privatization turned out to be abysmal failures; communitization a great, and continuing, success. We relate all this to the differing patterns of interaction between four fundamental forms of social solidarity - individualism (eg markets), hierarchy (eg governments and aid donors), egalitarianism (eg activist groups) and fatalism (eg carriers of the “double burden”: poverty and social exclusion) - and go on to show that only when each is (a) able to make its “voice” heard and (b) is following its dharma5 (acting according to its distinctive morality rather than undermining it) do we get development. REDD+6, we then show, using examples of its implementation in Africa, is unremittingly hierarchical and does not satisfy these two conditions. We conclude with some suggestions for remedying these policy defects.
在整个 "援助时代"(1944-1989 年)4 ,发展一直被视为本质上是经济性的。然而,人们越来越清楚地认识到,发展只是经济的结果。使发展成为可能的是其他东西--权利、民主化......社会资本。因此,我们需要一种不同的模式,我们首先通过过去半个世纪对尼泊尔森林进行的各种 "试验"--国有化、私有化和社区化--来勾勒这种模式。国有化和私有化最终都以失败告终,而社区化则取得了巨大的、持续的成功。我们将这一切与四种基本的社会团结形式--个人主义(如市场)、等级制度(如政府和援助捐赠者)、平等主义(如激进团体)和宿命论(如 "双重负担":贫困和社会排斥的承载者)--之间不同的互动模式联系起来,进而表明,只有当每种形式(a)都能够发出自己的 "声音",(b)都遵循自己的法则5 (按照自己独特的道德行事,而不是破坏它),我们才能获得发展。REDD+6 在非洲的实施实例表明,REDD+6 是等级森严的,不符合这两个条件。最后,我们提出了一些弥补这些政策缺陷的建议。

Integrating gender-disaggregated data and adopting a gender-focused perspective are crucial for a comprehensive understanding of climate change issues. This study provides empirical evidence from two ethnic minorities in Vietnam, highlighting how perceptions of livelihood resilience vary by gender, geographical context, and ethnicity, with a particular emphasis on their intersections. Over 13 months, data were gathered through 3 focus group discussions, in-depth interviews with 9 key informants, field observations, and surveys of 136 households. The findings revealed a low average Household Livelihood Resilience (HLR) score of 0.434, indicating limited resilience among forest-dependent households facing external shocks. Notably, a significant gender gap was evident, with men demonstrating higher resilience levels than women, a disparity attributed to entrenched social norms and cultural practices. Women, often confined to domestic roles, faced barriers to community involvement and access to financial resources, which weakened their ability to cope with and recover from adverse events. To address these issues, the study advocates for climate actions that prioritize gender equality and aim to enhance women's resilience. This includes amplifying their voices through tailored training programs and initiatives such as women-managed microfinance groups. The study also emphasizes the policy implications for advancing gender equality, sustainable forest management, and livelihood resilience. However, this work has limitations, including a small sample size and reliance on self-reported data, which may introduce biases. Future research should involve a larger, more diverse sample of forest-dependent communities and examine various dimensions of vulnerability to provide a more nuanced understanding of resilience factors.
整合按性别分列的数据并采用性别视角对于全面了解气候变化问题至关重要。本研究提供了来自越南两个少数民族的经验证据,强调了不同性别、不同地理环境和不同民族对生计恢复能力的看法是如何不同的,并特别强调了它们之间的交叉点。在 13 个月的时间里,通过 3 次焦点小组讨论、对 9 位关键信息提供者的深入访谈、实地观察以及对 136 户家庭的调查收集了数据。调查结果显示,家庭生计复原力(HLR)平均得分较低,仅为 0.434 分,这表明依靠森林为生的家庭面对外部冲击时的复原力有限。值得注意的是,性别差距明显,男性的复原力高于女性,这种差距归因于根深蒂固的社会规范和文化习俗。妇女往往局限于家庭角色,在参与社区活动和获得财政资源方面面临障碍,这削弱了她们应对不利事件和从不利事件中恢复的能力。为解决这些问题,本研究倡导采取以性别平等为优先事项、旨在增强妇女复原力的气候行动。这包括通过量身定制的培训计划和妇女管理的小额信贷团体等举措来扩大她们的声音。该研究还强调了促进性别平等、可持续森林管理和生计恢复力的政策影响。然而,这项工作也有局限性,包括样本量较小和依赖自我报告数据,这可能会带来偏差。未来的研究应涉及更大、更多样化的以森林为生的社区样本,并研究脆弱性的各个层面,以提供对复原力因素更细致入微的理解。

Ports are increasingly ‘greening’ operations to protect their ‘license to operate’ by integrating social-environmental considerations into their management and reporting on their sustainability performance. In this research, we develop a novel method for port sustainability performance (PSP) assessment that combines science-based knowledge with place-based contextualisation. Specifically, we address a recognised challenge of combining global (‘top-down’) techno-scientifically oriented indicators with place-based locally relatable (‘bottom-up’) contexts in sustainability performance, in addition to addressing limitations encountered in empirical verification. First, a critical evaluation of the international literature on port sustainability assessments is undertaken to distil commonalities in global performance indicators, and to identify typical frames used in the design of sustainability performance indices. We apply this learning, together with place-based experiential knowledge, to develop a science-based framework for a Port Sustainability Performance (PSP) Index that is explicitly aligned with the Sustainability Development Goals (SDGs). We then apply a co-design process to demonstrate local customisation of the index to derive place-based quantifiable measures and targets. Further, for easy-to-use empirical verification, a simple spreadsheet is applied to develop a flexible weighted scoring matrix. The matrix uses place-based rating systems for selected measures and associated targets, and aggregates allocated scores into informative outputs. Finally, the concept of Circles of Sustainability is adapted for ports to visually display sustainability performance, in alignment with related SDGs. This research contributes to bridging the science-practice divide in reporting on port sustainability performance.
港口正日益 "绿化 "其运营,通过将社会环境因素纳入其管理并报告其可持续发展绩效来保护其 "运营许可"。在这项研究中,我们开发了一种新的港口可持续发展绩效(PSP)评估方法,该方法将科学知识与地方背景相结合。具体来说,除了解决经验验证中遇到的局限性之外,我们还解决了一个公认的难题,即如何将可持续性绩效中以技术科学为导向的全球指标("自上而下")与以地方为基础的地方相关指标("自下而上")相结合。首先,我们对有关港口可持续性评估的国际文献进行了批判性评估,以提炼出全球绩效指标的共性,并确定在设计可持续性绩效指数时使用的典型框架。我们运用所学知识和基于地方的经验知识,为港口可持续发展绩效(PSP)指数制定了一个以科学为基础的框架,并明确与可持续发展目标(SDGs)保持一致。然后,我们采用共同设计流程来展示该指数的本地定制,从而得出基于地方的可量化措施和目标。此外,为了便于使用经验验证,我们还采用了一个简单的电子表格来开发一个灵活的加权评分矩阵。该矩阵对选定的措施和相关目标采用基于地方的评级系统,并将分配的分数汇总为信息输出。最后,根据相关的可持续发展目标,对可持续发展圈的概念进行了调整,以直观地显示港口的可持续发展绩效。这项研究有助于弥合港口可持续发展绩效报告中科学与实践之间的鸿沟。

<div><div>The purpose of this study is to develop a new concept of livability as "livable housing" in order to identify the factors that determine the subjective satisfaction of residents with the internal and surrounding environment of the housing and to estimate its level among urban neighborhoods with subjective and objective data. In order to fill the knowledge gap in livability studies, especially housing livability, the present study has looked at the link between livability and housing indicators and has evaluated this link among the residents of urban neighborhoods with different socio-economic contexts. This study has been evaluated the indicators of livable housing in an empirical analysis among the neighborhoods of Karaj metropolitan area (as a leading city) with the cluster sampling method and choosing 8 neighborhoods (as the scope of the research) as well as 402 cases (as a sample statistics derived from Cochran's formula).In this evaluation, the questionnaire with (72 sub-indicators in 15 groups) is the main criterion for data collection, and the analyzes are using statistical and spatial combined methods. The statistical analysis of the questionnaire includes preparing the data for weighting and determining the important and influential factors with the exploratory factor analysis method in the SPSS environment. The stratification of neighborhoods is done with the multi-criteria decision-making model (TODIM) by combining the raw data and the weight of indicators extracted from the EFA method. Also, the accuracy of the results has been measured with the RMS method and the use of spatial methods in (GIS).The results showed environmental, social, economic and physical macro-factors respectively have the greatest effects on the livability of housing. The indicators of facilities and infrastructures, open and public space, cleanliness and pollution were the indicators of increasing livability and satisfaction, and the indicators of place connection and belonging, access and transportation, personal and social security were the indicators of decreasing livability. In general, the neighborhoods are in different conditions of housing livability and without continuity and principles of regularity. This difference in the different effects of indicators in neighborhoods is due to the inherent differences of neighborhoods and people's mental filters. The (89%) overlap obtained from the validation of the results indicates the existence of a very insignificant difference and acceptable agreement of the results of the two methods of spatial-spatial analysis. Considering the importance of the relationship between man and the urban environment and the quality of human life, it is recommended to pay special attention to community-orientedness and local assets and a bottom-up approach in livability surveys at any scale. Also, this study suggests important policy implications for achieving urban sustainability by improving housing livability.</div></d
本研究的目的是提出 "宜居住房 "这一新的宜居概念,以确定决定居民对住房内部和周边环境主观满意度的因素,并通过主观和客观数据估算城市街区的宜居水平。为了填补宜居性研究,尤其是住房宜居性研究方面的知识空白,本研究探讨了宜居性与住房指标之间的联系,并对不同社会经济背景的城市街区居民的这一联系进行了评估。本研究采用聚类抽样法,在卡拉杰都市区(作为主要城市)的居民区中选择了 8 个居民区(作为研究范围)和 402 个案例(作为根据科克伦公式得出的样本统计),对宜居住房指标进行了实证分析评估。问卷的统计分析包括准备加权数据,以及在 SPSS 环境下使用探索性因素分析方法确定重要和有影响的因素。通过结合原始数据和从 EFA 方法中提取的指标权重,利用多标准决策模型(TODIM)对街区进行分层。结果显示,环境、社会、经济和物理宏观因素对住房宜居性的影响最大。设施和基础设施、开放和公共空间、清洁和污染等指标是提高宜居性和满意度的指标,而地方联系和归属感、通达性和交通、个人和社会安全等指标则是降低宜居性的指标。总体而言,这些街区的住房宜居性状况各不相同,没有连续性和规律性原则。邻里之间指标影响的差异是由于邻里之间的内在差异和人们的心理过滤造成的。从结果验证中获得的(89%)重合度表明,两种空间分析方法的结果存在着非常不明显的差异和可接受的一致性。考虑到人与城市环境的关系以及人类生活质量的重要性,建议在任何规模的宜居性调查中都要特别关注社区导向性和地方资产,以及自下而上的方法。此外,本研究还提出了通过提高住房宜居性实现城市可持续性的重要政策含义。

Addressing the ecological impacts of transport corridors while planning any transport network is paramount for a better of understanding ecological processes, biodiversity distribution, and ecosystem resilience. Here, we evaluated the impacts of railway edges on edaphic parameters, plant diversity, and composition in the northwestern Himalaya as a function of perpendicular distance from the railway track. In 2014 and 2017, we sampled vegetation plots across 31 sites distributed along 119 km of the Kashmir railway to test the effect of railway tracks on edaphic and vegetative parameters in short-term periods. T-shaped plots were laid comprising four sub-plots, one parallel to the track and the other three perpendiculars to it. We adopted the Mountain Invasion Research Network road survey methodology for data collection. We found (i) an increasing trend in all soil parameters (electrical conductivity, salinity, organic carbon, available nitrogen, and available phosphorus), except pH, as the distance from the railway track increased; (ii) significant railway edge effects on the importance value index of plant growth forms, life span, nativity and taxonomic group across space (distance of plots from the track) and time (2014–2017); and (iii) a significant spatiotemporal railway edge effects on plant species composition. Our results are pioneering in showing that railway tracks crossing through different ecosystems alter the edaphic conditions, resulting in direct and indirect edge effects on key abiotic and biotic factors, which in turn impact the vegetation of the surrounding natural habitats on both sides of the railway track. Our study contributes toward a better understanding of the role of anthropogenic edges like railways on edaphic parameters and vegetation distribution.
在规划任何交通网络时,解决交通走廊对生态的影响对于更好地了解生态过程、生物多样性分布和生态系统恢复能力至关重要。在此,我们评估了铁路边缘对喜马拉雅山西北部的土壤参数、植物多样性和组成的影响,以及与铁路轨道垂直距离的函数关系。2014 年和 2017 年,我们在克什米尔铁路 119 公里沿线分布的 31 个地点进行了植被地块采样,以检验铁轨在短期内对土壤环境和植被参数的影响。T 型地块由四个子地块组成,其中一个与铁轨平行,另外三个与铁轨垂直。我们采用山区入侵研究网络道路调查方法收集数据。我们发现:(i) 除 pH 值外,所有土壤参数(电导率、盐度、有机碳、可利用氮和可利用磷)都随着与铁轨距离的增加而呈上升趋势;(ii) 在不同空间(地块与铁轨的距离)和时间(2014-2017 年)内,铁路边缘对植物生长形式、寿命、原生性和分类群的重要价值指数具有显著影响;(iii) 铁路边缘对植物物种组成具有显著的时空影响。我们的研究结果开创性地表明,穿越不同生态系统的铁轨会改变土壤条件,从而对关键的非生物和生物因素产生直接和间接的边缘效应,进而影响铁轨两侧周围自然栖息地的植被。我们的研究有助于更好地理解铁路等人为边缘对土壤环境参数和植被分布的作用。

Mangrove forests along the Vietnamese coastline provide multiple ecological, environmental, and economic services, including being a habitat for different flora and fauna, shoreline protection from erosion, storms, and waves, and providing several raw materials for industries. The coast of Quang Ngai province in Central Vietnam didn't get much attention from the research community, particularly on the mangrove reforestation programs and coastal environmental changes in the province. In the present study, we investigated the shoreline changes in Quang Ngai Province since the late 1980s, recent mangrove reforestation initiatives, and its progress in the area using medium-resolution Landsat imagery series and Sentinel-2 data. The results were compared with mangrove areas estimated from high-resolution RapidEye and PlanetScope imagery for accuracy analysis. There has been a slight increase in the area occupied by mangroves along the Quang Ngai coast between 2007 and 2022 compared to the area of mangrove patches in the 1980s. An increase in the area of inland mangroves offers various ecosystem services to the regional community, improvement in livelihood, and quality of environment. Our results indicated that the erosion-accretion changes along the coast of Quang Ngai were not unique and that some areas, such as the urbanized northern part, have eroded higher than southern areas except where sediment supply from larger rivers in the province is high. The mangroves planted in Bau Ca Cai wetlands indicated a success and such initiatives can be conducted throughout the south-central coast of Vietnam for long-term coastal protection.
越南海岸线上的红树林提供了多种生态、环境和经济服务,包括不同动植物的栖息地,保护海岸线免受侵蚀、风暴和海浪的侵袭,以及为工业提供多种原材料。越南中部广义省的海岸并未受到研究界的广泛关注,尤其是该省的红树林造林计划和海岸环境变化。在本研究中,我们利用中分辨率 Landsat 影像系列和 Sentinel-2 数据调查了广义省自 20 世纪 80 年代末以来的海岸线变化、近期的红树林造林计划及其在该地区的进展情况。研究结果与根据高分辨率 RapidEye 和 PlanetScope 图像估算的红树林面积进行了比较,以进行精度分析。与 20 世纪 80 年代的红树林斑块面积相比,2007 年至 2022 年期间广义沿海地区的红树林面积略有增加。内陆红树林面积的增加为该地区社区提供了各种生态系统服务,改善了生计和环境质量。我们的研究结果表明,广义省沿海地区的侵蚀-增生变化并非独一无二,除了该省较大河流的泥沙供应量较高的地区外,一些地区(如城市化的北部地区)的侵蚀程度高于南部地区。在 Bau Ca Cai 湿地种植的红树林取得了成功,此类举措可在越南中南部沿海地区推广,以实现对海岸的长期保护。

Given that the existing literature has rarely considered gender inequality when assessing the social forces affecting biodiversity loss, this paper examines whether biodiversity loss can be reduced by improving women's employment opportunities in the labor market. We used a comprehensive cross-national dataset of 84 countries to examine the pathways by which female labor force participation rates (Flfpr) reduce biodiversity loss. It was found that there is an inverted U-shaped curve relationship between Flfpr and biodiversity loss, and the conclusion still holds after a series of robustness tests and validation by machine learning methods. The mechanism of Flfpr on biodiversity loss varies by economic level and geographic location and Flfpr is underutilized as an important tool to address biodiversity loss in developing countries. The transmission channels through which Flfpr reduces biodiversity loss are not the same, and the high-tech industry sector exhibits significant heterogeneity. The effect of reducing biodiversity loss is more pronounced in regions with high levels of female political participation. This paper shows that improving gender inequality and increasing Flfpr around the world may have synergistic effects on curbing biodiversity loss. Our study provides new insights into the relationship between active females in the labor market and biodiversity loss from both macro-regional and micro-industry perspectives, enriching the case for gender-responsive biodiversity practices under the UN Convention on Biological Diversity.
鉴于现有文献在评估影响生物多样性丧失的社会力量时很少考虑性别不平等问题,本文探讨了是否可以通过改善女性在劳动力市场的就业机会来减少生物多样性的丧失。我们利用 84 个国家的综合跨国数据集,研究了女性劳动力参与率(Flfpr)减少生物多样性损失的途径。研究发现,Flfpr 与生物多样性损失之间存在倒 U 型曲线关系,经过一系列稳健性检验和机器学习方法验证后,该结论仍然成立。Flfpr对生物多样性丧失的影响机制因经济水平和地理位置而异,Flfpr作为发展中国家解决生物多样性丧失问题的重要工具还未得到充分利用。Flfpr 减少生物多样性损失的传导渠道不尽相同,高科技产业部门表现出显著的异质性。在女性参政程度较高的地区,减少生物多样性损失的效果更为明显。本文表明,在全球范围内,改善性别不平等和提高 Flfpr 可能会对遏制生物多样性丧失产生协同效应。我们的研究从宏观区域和微观行业两个角度为活跃于劳动力市场的女性与生物多样性丧失之间的关系提供了新的见解,丰富了《联合国生物多样性公约》下促进性别平等的生物多样性实践的案例。

Prior studies suggest that climate disasters increase corruption due to the windfall of donations. However, is it possible that corruption increases the probability of occurrence and consequences of climatic disasters? This paper investigates the intricate relationship between corruption and climate risk using a comprehensive panel dataset spanning 171 countries from 2006 to 2019. Employing robust econometric methodologies, including fixed effects and a two-step generalised method of moments, we explore whether corruption exacerbates the probability and severity of climate-related disasters. Our findings reveal a significant positive association between corruption levels and climate risk, indicating that corruption amplifies both the frequency and consequences of climate disasters. Importantly, this relationship holds across diverse geographical locations and development statuses, with a particularly pronounced impact observed in developing countries where corruption compounds existing infrastructural vulnerabilities. These findings highlight the imperative for policymakers to address corruption alongside environmental and geographical factors in crafting effective strategies to mitigate climate-related disasters and enhance global resilience.

先前的研究表明,气候灾害会因捐赠的意外之财而增加腐败。然而,腐败是否有可能增加气候灾害的发生概率和后果呢?本文利用 2006 年至 2019 年横跨 171 个国家的综合面板数据集,研究了腐败与气候风险之间错综复杂的关系。我们采用稳健的计量经济学方法,包括固定效应和两步广义矩方法,探讨了腐败是否会加剧气候相关灾害的发生概率和严重程度。我们的研究结果表明,腐败程度与气候风险之间存在明显的正相关关系,表明腐败会扩大气候灾害的频率和后果。重要的是,这种关系适用于不同的地理位置和发展状况,在发展中国家观察到的影响尤为明显,因为腐败加剧了现有基础设施的脆弱性。这些发现突出表明,决策者在制定有效战略以减轻与气候有关的灾害和提高全球抗灾能力时,必须同时考虑环境和地理因素以及腐败问题。

In contemporary literature, extensive research has focused on the influence of environmental taxation on the environmental performance of industrial sectors. However, it is still uncommon in the existing literature how corporate statutory tax rate (CTR) affects environmental performance. Therefore, this study aims to empirically investigate the relationship between CTR and environmental quality (ENQ) as well as environmental innovation (EIN). To conduct this analysis, we utilized 19 years of financial data spanning from 2001 to 2019 across all 48 Asian economies. Our research employed both panel quantile regression (PQR) and system GMM models for the regression analysis. The empirical findings reveal that the corporate statutory tax rate has a positive impact on CO2 emissions, leading to deterioration of the environmental quality, while simultaneously exerting a negative influence on environmental innovation, inhibiting green innovation. These effects of the CTR on ENQ and EIN remained consistent even when controlling for factors such as economic growth, foreign capital, financial development, and environmental taxation. These findings have significant policy implications, suggesting the need for a reevaluation of current tax policies and the introduction of tax rebates for companies striving to enhance their environmental sustainability. This study contributes to the literature by shedding light on the adverse consequences of high taxation on the environmental performance of businesses.

在当代文献中,大量研究集中于环境税对工业部门环境绩效的影响。然而,企业法定税率(CTR)如何影响环境绩效,在现有文献中仍不多见。因此,本研究旨在实证研究企业法定税率与环境质量(ENQ)和环境创新(EIN)之间的关系。为了进行分析,我们使用了从 2001 年到 2019 年的 19 年财务数据,涵盖了所有 48 个亚洲经济体。我们的研究采用了面板量化回归(PQR)和系统 GMM 模型进行回归分析。实证研究结果表明,企业法定税率对二氧化碳排放有正向影响,导致环境质量恶化,同时对环境创新有负向影响,抑制绿色创新。即使控制了经济增长、外资、金融发展和环境税等因素,公司法定税率对 ENQ 和 EIN 的影响仍然是一致的。这些研究结果具有重要的政策意义,表明有必要重新评估现行税收政策,并为努力提高环境可持续性的企业提供退税。本研究阐明了高税收对企业环境绩效的不利影响,为相关文献做出了贡献。

Urban development in African countries significantly impacts environmental sustainability and city resilience, particularly in flood risk management. The Accra Metropolis, in particular, faces increasingly prevalent annual floods that disproportionately affect the urban poor living in informal settlements, resulting in significant loss of life and disruption of livelihoods. This study developed a GIS-based flood risk mapping framework that integrates artificial neural network (ANN) and cellular automata (CA) modelling with multi-criteria decision analysis. This hybrid approach was employed to predict flood scenarios for the Metropolis in 2032 and 2042. The framework incorporated six hydro-geomorphological indicators influencing extreme events: LULC, slope, elevation, drainage density, soil type, and proximity to rivers. The study analysed LULC projections, revealing a trend of substantial urban expansion with an estimated 10.9% increase in built-up areas within the next 20 years. This growth is expected to significantly heighten future flood risk in both the central upstream and downstream portions of the Metropolis, particularly in low-lying informal settlements close to the Odaw River and Korle Lagoon. Model performance was validated by ROC curve analysis, with AUC values of 0.927 and 0.922 for 2032 and 2042, respectively, which resonates with the records of previous flood distribution studies of the area. This study highlights the crucial need for sustainable urban development, improved infrastructure, and proactive flood mitigation measures in Accra to assist urban planners, policymakers, and stakeholders in managing flood risks effectively.

非洲国家的城市发展极大地影响了环境的可持续性和城市的抗灾能力,特别是在洪水风险管理方面。尤其是阿克拉大都市,每年面临的洪灾越来越普遍,对居住在非正规住区的城市贫民造成了极大的影响,导致重大生命损失和生计中断。本研究开发了一个基于地理信息系统的洪水风险绘图框架,该框架将人工神经网络(ANN)和单元自动机(CA)建模与多标准决策分析相结合。采用这种混合方法预测了大都会在 2032 年和 2042 年的洪水情况。该框架包含影响极端事件的六个水文地质指标:土地利用、土地利用变化、坡度、海拔、排水密度、土壤类型和靠近河流的程度。研究分析了土地利用、土地利用变化(LULC)预测,揭示了城市大幅扩张的趋势,预计未来 20 年内建成区面积将增加 10.9%。预计这一增长将大大增加大都会中心区上游和下游地区未来的洪水风险,尤其是在靠近奥多河和科勒泻湖的低洼非正规住区。通过 ROC 曲线分析验证了模型的性能,2032 年和 2042 年的 AUC 值分别为 0.927 和 0.922,这与该地区以前的洪水分布研究记录相吻合。这项研究强调了在阿克拉进行可持续城市发展、改善基础设施和采取积极的洪水缓解措施的迫切需要,以帮助城市规划者、决策者和利益相关者有效管理洪水风险。
