ABSTRACTThe G7 nations is a major global consumers of natural resources and energy. These nations are confronted with substantial obstacles in their pursuit of sustainable growth through energy transition, while upholding their status as global economic leaders. As a result, this current study conducted an aggregated and disintegrating analysis on the heterogeneous role of green energy innovation on energy transition in G7 nations. Green energy innovation was disintegrated into hydro, solar and wind energy. Moreover, the heterogeneous effects of green innovation in solar, hydro and wind on energy transition was investigated, an analysis that has not been previously examined. For the econometric estimation, we adopted the Quantile-on-Quantile Regression (QQR) and the quantile causality method. The results of the QQR indicates that the positive role of green energy innovation on energy transition in all of the G7 nations. However, this positive role is more dominant in five G7 nations, namely Italy, Germany, Japan, the UK and the USA. Additionally, the result also highlights that the connection between green energy innovation and energy transition is differs across the various quantiles for different nations. Moreover, the quantile causality analysis indicates that green energy innovation has the potential to predict future values in energy transition within the G7 nations.

ABSTRACTIn contemporary times, emerging economies are intended to achieve higher economic growth via foreign direct investment and technological innovation. However, due to increased environmental challenges, these economies are adopting green energy as the key source of environmental recovery and net zero emissions. The present study investigates the influence of FDI, technological innovation, green energy, and trade on carbon emissions in BRICS economies during 1990–2022. This study also considers the role of economic expansion in identifying the environmental Kuznets curve (EKC). Using several panel diagnostic and cointegration tests, this study validates the slope heterogeneity and the existence of the cointegration between variables. Due to the non-normal data dispersion, this study uses novel moments quantile regression, while bootstrap quantile regression is used for the robustness. The results examined asserted the presence of the EKC hypothesis in the region, where the initial growth enhances emissions while after reaching at a threshold level, the emission level tends to reduce and environmental quality improves. Besides, this study observed that foreign trade and technological innovation are the key drivers of environmental degradation as these indicators significantly enhances pollution emissions. In contrast, foreign investment, energy efficiency, renewable electricity output, and renewable’s consumption significantly improve environmental quality by declining carbon emissions. Following the empirical results, the policy recommendations asserted enhanced investment in renewable and energy efficiency sectors while attracting more foreign investment for sustainable development.KEYWORDS: Foreign direct investmentgreen energyenvironmental Kuznets curvetradetechnological innovationcarbon emissions Disclosure statementNo potential conflict of interest was reported by the authors.
当代,新兴经济体希望通过外国直接投资和技术创新来实现更高的经济增长。然而,由于日益严峻的环境挑战,这些经济体正在采用绿色能源作为环境恢复和净零排放的主要来源。本研究调查了1990-2022年金砖国家FDI、技术创新、绿色能源和贸易对碳排放的影响。本文还考虑了经济扩张对环境库兹涅茨曲线(EKC)识别的作用。通过面板诊断和协整检验,本研究验证了斜率异质性和变量之间协整的存在。由于数据的非正态离散性,本研究采用了新颖的矩分位数回归,而鲁棒性采用了自举分位数回归。研究结果证实了EKC假设在该区域的存在,该区域的初始增长增加了排放,而在达到阈值水平后,排放水平趋于减少,环境质量得到改善。此外,研究发现,对外贸易和技术创新是环境退化的关键驱动因素,这些指标显著增加了污染排放。相比之下,外商投资、能源效率、可再生能源发电量和可再生能源消费通过降低碳排放显著改善了环境质量。根据实证结果,政策建议主张增加对可再生能源和能源效率部门的投资,同时吸引更多的外国投资促进可持续发展。关键词:外商直接投资绿色能源环境库兹涅茨曲线贸易技术创新碳排放披露声明作者未发现潜在利益冲突。

ABSTRACTIdentifying climate change risks, vulnerabilities of exposed populations, and implemented responses to climate change are crucial for developing effective strategies to mitigate climate hazards. However, existing climate change assessment indexes still have some limitations, such as insufficient consideration of policy response, limited coverage of countries, and lack of a multidimensional perspective. In this study, we developed a novel climate change impacts and responses (CCIR) index that incorporates comprehensive information on climate risks, disease burden, and mitigation actions in response to climate risks and damage. To our best knowledge, the CCIR index is the first of its kind that explores variations in climate risks, impacts, and responses across countries to identify vulnerabilities and find more targeted solutions. A positive correlation was found between the CCIR index and national Gross Domestic Product per capita, indicating that wealthier countries might allocate more resources toward mitigating climate impacts. Moreover, countries with better climate education tended to have a lower carbon footprint, highlighting the importance of climate education. Furthermore, countries with lower risks of emerging infectious diseases were more likely to consume more renewable energy. The results highlight the value of using a multidimensional CCIR framework to analyze the interactions among socioeconomic factors, environmental policies, and climate change risks in 158 countries. This comprehensive approach provides actionable insights to mitigate climate impacts and improve national climate resilience. It also streamlines monitoring efforts and promotes joint climate action across international boundaries. By identifying climate risks and opportunities, the CCIR index can help policymakers design, refine, and implement adaptation policies and measures to respond to the impacts of climate change.Key policy highlights CCIR index evaluates countries’ climate change mitigation and adaptation efforts.Wealthier countries invest more in mitigating climate change.Lower-income and coastal nations are vulnerable to climate change impacts.Countries at lower risk of emerging infectious diseases consume more renewable energy.Climate change education is associated with a lower carbon footprint.KEYWORDS: Climate risksclimate adaptationvulnerabilitygreenhouse gas emissiondisease burdenequity considerations Acronyms CART=Classification and Regression TreesCCPI=Change Performance IndexDALYs=Disability-Adjusted Life YearsDSR=Drivers-State-ResponsesEPI=Environmental Performance IndexFAO=Food and Agriculture OrganizationGBD=Global Burden of DiseaseGDIS=Geocoded DisastersGDP=Gross Domestic ProductGHG=Greenhouse GasIEA=International Energy AgencyIRENA=International Renewable Energy AgencyVIF=Variance Inflation FactorWOS=Web of ScienceCCIR=indicatorsAHO=Air Pollution-related Health OutcomeCCE=Climate Change EducationCCIR=Climate Change Impacts and Response
识别气候变化风险、暴露人群的脆弱性以及实施应对气候变化的措施,对于制定有效的缓解气候灾害战略至关重要。然而,现有的气候变化评估指标仍存在一定的局限性,如对政策响应考虑不足、覆盖国家范围有限、缺乏多维度视角等。在这项研究中,我们开发了一个新的气候变化影响和响应(CCIR)指数,该指数综合了气候风险、疾病负担和应对气候风险和损害的减缓行动的综合信息。据我们所知,CCIR指数首次探讨了各国在气候风险、影响和应对方面的差异,以确定脆弱性并找到更有针对性的解决方案。CCIR指数与国家人均国内生产总值之间存在正相关关系,这表明较富裕的国家可能会分配更多的资源来缓解气候影响。此外,气候教育更好的国家往往碳足迹更低,这凸显了气候教育的重要性。此外,新发传染病风险较低的国家更有可能消耗更多的可再生能源。研究结果强调了使用多维CCIR框架分析158个国家的社会经济因素、环境政策和气候变化风险之间相互作用的价值。这种综合方法为减轻气候影响和提高国家气候适应能力提供了可行的见解。它还简化了监测工作,促进了跨国界的联合气候行动。通过识别气候风险和机遇,CCIR指数可以帮助决策者设计、完善和实施适应政策和措施,以应对气候变化的影响。CCIR指数评估各国减缓和适应气候变化的努力。富裕国家在减缓气候变化方面投入更多。低收入和沿海国家容易受到气候变化的影响。新发传染病风险较低的国家消耗更多的可再生能源。气候变化教育与低碳足迹有关。关键词:气候风险气候适应脆弱性温室气体排放疾病负担公平性考虑首字母缩写CART=分类与回归树ccpi =变化绩效指数dalys =残疾调整寿命年sdsr =驱动因素-状态-响应epi =环境绩效指数fao =粮食及农业组织bd =全球疾病负担dis =地理编码灾害gdp =国内生产总值ghg =温室气体iea =国际能源机构rena =国际可再生能源机构vif =方差通货膨胀因子wos =科学网ecr =指标saho =空气污染相关健康结果ecce =气候变化教育ccir =气候变化影响与应对ccr =气候变化风险sctf =气候金融egu =能源使用eeid =新发传染病exw =极端天气frn =森林资源ge =温室气体排放shit =健康影响shri =热相关疾病rcc =应对气候变化eu =可再生能源使用披露声明作者未报告潜在的利益冲突。谢思:概念化、数据策展、形式分析、调查、方法论、软件、验证、可视化、写作-原稿、写作-审稿编辑。李慧敏:概念化,数据管理,形式分析,调查,验证,写作-审查和编辑。刘敬姝:概念、软件、验证、写作-评审与编辑。韩乐飞:软件,验证,写作-审查和编辑。张晓曦:概念化、数据策展、形式分析、写作-评审与编辑。郭晓奎:审稿、写作、评审、编辑。周晓农:验证、写作、评审、编辑。乐山修:方法论、监督、验证、撰写-原稿、撰写-审稿、编辑。郝茵:概念化、数据策展、形式分析、方法论、监督、验证、写作-原稿、写作-评审与编辑。尹坤:概念化、形式分析、资金获取、调查、方法论、项目管理、监督、验证、写作—初稿、写作—评审与编辑。同意发表作者愿意允许杂志发表这篇文章。本研究得到国家自然科学基金项目(项目号:22104090)和上海市自然科学基金项目(项目号:22ZR1436200)的资助。本研究由国家自然科学基金项目(71904104)资助。

ABSTRACTMalaysia’s commitment to ecological quality is evident in its agendas for achieving a sustainable environment by 2030. However, hindrances like challenges towards energy transition efforts, stable political institutions, unclean economic globalization practices, and transiting to a complex economy could potentially delay the nation’s attainment of its environmental goals. Against this backdrop, the current study focuses on examining the roles of political risk, economic globalization, energy transition, and economic complexity on ecological sustainability in Malaysia. In contrast to previous studies, this study innovatively incorporates a dummy variable to account for potential structural breaks that may occur during the study period. Furthermore, this study used an innovative environmental proxy which incorporates both the demand and supply aspect of the environment during computation. Using the time series data from 1984 to 2018 and employed the ARDL estimator method, the empirical results indicate that economic globalization is associated with ecological deterioration in Malaysia in the long run. On the other hand, economic complexity, political stability, and energy transition are shown to promote ecological sustainability in Malaysia in the long run. Moreover, the bootstrap time varying causality method demonstrates that each of the regressors has the capacity to predict the load capacity factor during distinct sub-periods.KEYWORDS: Malaysiaeconomic complexitypolitical stabilitybootstrap time varying causalityenergy transition Disclosure statementWe can assert that there are no conflicts of interest concerning this research.Ethical ApprovalThe ethical standards and practices required were been observed in this research.Authors ContributionAll the authors contributed equally to the final manuscript.Availability of dataThe corresponding author can provide you with the data upon request.Additional informationFundingNo specific funding was granted for this study
摘要马来西亚对生态质量的承诺体现在其到2030年实现可持续环境的议程中。然而,能源转型努力面临的挑战、稳定的政治制度、不清洁的经济全球化实践以及向复杂经济的过渡等障碍可能会推迟国家实现其环境目标的时间。在此背景下,本研究将重点研究政治风险、经济全球化、能源转型和经济复杂性对马来西亚生态可持续性的影响。与以往的研究相比,本研究创新性地采用了一个虚拟变量来解释研究期间可能发生的潜在结构断裂。此外,本研究使用了一种创新的环境代理,在计算过程中结合了环境的需求和供给方面。利用1984 - 2018年的时间序列数据,采用ARDL估计方法,实证结果表明,经济全球化与马来西亚生态恶化存在长期关联。另一方面,从长远来看,经济复杂性、政治稳定性和能源转型将促进马来西亚的生态可持续性。此外,自举时变因果关系方法表明,每个回归量都有能力预测不同子周期的负荷能力因子。关键词:马来西亚,经济复杂性,政治稳定,自举,时变因果关系,能源转型,披露声明,我们可以断言,在这项研究中没有利益冲突。伦理批准本研究符合伦理标准和实践要求。作者的贡献所有作者对最终稿件的贡献相同。数据的可用性通讯作者可根据您的要求提供数据。本研究未获得专项资金

ABSTRACTThe nexus of tourism and sustainability has emerged as a catchphrase in academic literature in recent years. The present study employed an integrated path model to investigate the increasing significance of sustainable tourism, which is attributed, in part, to the penchant of domestic tourists to consume locally sourced food. The investigation additionally ascertains the potential influence of local food products on the various dimensions of sustainability, including economic, cultural, social, and environmental aspects. Data is collected using a purposeful sample technique, with 462 responses from domestic tourists to the Kashmir Valley being screened and analyzed using SPSS and partial least squares structural equation modeling (PLS-SEM). The findings derived from PLS-SEM analysis demonstrate that the act of domestic tourists consuming locally produced food has a considerable and statistically significant influence on sustainability-focused tourism. Furthermore, the consumption of locally grown foods has a positive influence on various dimensions of sustainability, including the economic, social, cultural, and environmental aspects. The present study contributes to the existing scholarly literature on the subjects of regional gastronomy and sustainable tourism. In the current work, the authors aim to present the potential of local food to promote sustainable tourism in the tourist host regions.

ABSTRACTAligned with the recent trend of climate change mitigation and adaptation to rapid urbanization, sustainable urban development is crucial for creating resilient communities. Various international green building councils have developed Neighborhood Sustainability Assessment (NSA) tools that played an effective role in the urban growth of neighborhoods. However, there is no current NSA tool that includes all the categories required to achieve sustainability. Therefore, ten NSA tools were selected, analyzed, and compared. For an applicable comparative analysis, re-categorization and unifying processes of the selected NSA tools were performed. As a result, new integrated criteria were developed including seven main categories offering a valuable resource for evaluating neighborhood sustainability. The results also revealed that WELL Community V2 Q4, Fitwel CM V2.1, and BREEAM-CM V2012 tools demonstrate the highest efficiency by possessing six out of the seven integrated categories. The other NSA tools need to be improved with regard to the dimensions of sustainability. Furthermore, it was noted that all the selected NSA tools give major attention to the environmental conditions and facilities; however, other aspects such as the social, economic, and institutional features are being ignored. To sum up, the study proposes a novel approach that addresses these shortcomings by providing a more comprehensive framework that aims to support policy development and improve the effectiveness of neighborhood sustainability assessments.KEYWORDS: Sustainabilitygreen building rating systemsNeighborhood Sustainability Assessment (NSA) toolsintegrated criteriaurban development Disclosure statementNo potential conflict of interest was reported by the author(s).Authors’ contributionsElkamhawy was responsible for the literature review, data analysis, writing, review, and editing of the manuscript.

ABSTRACTThe continuously increasing demands of food, feed and various corn-derived products accelerate the concern about the corn production on environment. Nevertheless, few researches simultaneously address the issue from different perspectives of carbon, water and energy as well as their temporal variations. Herein, a systematic cradle-to-gate life cycle assessment of maize production was conducted with a case study in Shandong, China. Different midpoint and endpoint indices including 10-year average data from 2011 to 2020 and their temporal variations were investigated. The contribution analysis of different processes to these indices revealed that irrigation dominated the midpoint of water scarcity, whereas the sum of direct consumption, fertilizer and diesel production contributed more than 80% to all the other indices. The sensitivity analysis also illustrated that these environmental indices can be reduced by as high as 4% when the aforementioned inputs were individually decreased by 5%. The temporal variation of the global warming potential, aquatic eutrophication and fossil depletion demonstrated that all the three indices were decreased by about 25.0%–31.7% over the last decade. Further persistent efforts to enhance mechanized operation efficiency and explore green and efficient methods for fertilizer and diesel production were highlighted. Moreover, implementations of rational agricultural management such as scientific fertilization and water-efficient irrigation were suggested, in order to have an eco-friendly maize production system.KEYWORDS: Life cycle assessmentmaize productioncarbon footprintwater footprintenergy footprinttemporal variation AcknowledgmentsThis work was supported by the National Natural Science Foundation of China under Grant No. 21868011 and the Foundation of Guangxi Key Laboratory of Plant Functional Phytochemicals and Sustainable Utilization under Grant FPRU2020-2.Author contributionsXuan Wang: Investigation, data processing, data curation, writing – original draft.Lei Xiao: Visualization, data curation.Zhenyan Fan: Methodology, formal analysis.Yueyuan Chen: Investigation, funding acquisition.Zhifang Cui: Conceptualization, writing – review and editing, supervision, and funding acquisition.

摘要随着人们对食品、饲料和各种玉米衍生产品需求的不断增加,人们对玉米生产对环境的担忧日益加剧。然而,很少有研究同时从碳、水和能源的不同角度及其时间变化来解决这一问题。本文以山东省为例,对玉米生产从摇篮到大门的生命周期进行了系统评估。研究了2011 - 2020年10年平均数据的不同中点和终点指数及其时间变化。不同过程对这些指标的贡献分析表明,灌溉在水资源短缺的中点占主导地位,而直接消费、化肥和柴油生产的总和对其他所有指标的贡献都超过80%。敏感性分析还表明,当上述投入单项减少5%时,这些环境指标最高可降低4%。全球变暖潜势、水体富营养化和化石耗竭的时间变化表明,近10年来这3个指标均下降了约25.0% ~ 31.7%。进一步坚持不懈地提高机械化作业效率,探索绿色高效的化肥和柴油生产方法。在此基础上,提出实施科学施肥、节水灌溉等合理的农业管理措施,构建生态友好型玉米生产体系。关键词:生命周期评估玉米产量碳足迹水足迹能源足迹时间变化王轩:调查、数据处理、数据整理、写作——原稿。雷晓:可视化,数据管理。范振岩:方法论,形式分析。陈月媛:调研,资金获取。崔志芳:概念、写作、审编、监督、资金获取。所有作者都对研究的构思和设计做出了贡献。所有作者共同审阅并批准稿件发表。数据和材料的可获得性本研究中使用或分析的数据集可根据通讯作者的合理要求提供。披露声明作者未报告潜在的利益冲突。项目资助:国家自然科学基金(No. 21868011)、广西植物功能化学物质与可持续利用重点实验室(FPRU2020-2)和山东科技大学资助。

ABSTRACTGovernments, companies and citizens around the world consider necessary to adopt a new circular economy (CE) model that allows solving the planet’s environmental challenges and guaranteeing sustainable economic growth. Europe advocates this philosophy, but there is no widely accepted index to measure CE implementation at a macro level. This paper proposes a new index based on principal component analysis for European Union countries that use all information available without losing any information by the dimensionality reduction and consider objective weights based on the percentage of variance that each one retains. Moreover, we develop a disaggregated analysis considering the CE dimensions set out in the ‘CE monitoring framework’, allowing a more comprehensive analysis than when using a single indicator of CE implementation. This method is also used to build an index of the degree of achievement of the sustainable development goals (SDGs) to see how they relate to the CE; the relationships between CE dimensions; and between SDGs. The results by geographical areas reveal a higher level of CE implementation in western European and EU-15 countries, with Luxembourg, Austria, Denmark, the Netherlands and Belgium alternately holding the top positions depending on the CE dimension considered. Therefore, the new European countries and the countries in the east must encourage measures to improve the implementation of the economy. In addition, there is a positive, strong and significant relationship with SDGs 8, 9 and 11, with both the overall CE implementation index and the disaggregated indices, and a negative one with 7 and 15.KEYWORDS: Circular economysustainable development goalssynthetic indicatorprincipal component analysisEuropean Union Highlights We propose new synthetic indices of the CE implementation and achievement of the SDGs.This proposal accounts for all existing information, leaving nothing out, however, irrelevant it may seem, and uses objective weights.The results show that Luxembourg, Austria, Denmark, the Netherlands and Belgium hold the top positions.Western European countries and those that make up the EU-15 are the ones that present the highest levels of CE implementation.There is a clear relationship between the SDGs 8, 9 and 11 and CE implementation.AcknowledgmentsSpecial thanks to the editor and the anonymous reviewers for their suggestions regarding this paper.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the Department of Applied Economics I, University of Castilla-La Mancha, Spain [grant numbers 00421I126].
摘要世界各国政府、企业和公民都认为有必要采用一种新的循环经济(CE)模式,以解决地球的环境挑战并保证可持续的经济增长。欧洲倡导这一理念,但没有一个被广泛接受的指标来衡量宏观层面的CE实施情况。本文提出了一种新的基于主成分分析的欧盟国家指数,该指数利用所有可用信息而不因降维而丢失任何信息,并根据每个国家保留的方差百分比考虑客观权重。此外,我们发展了一个分解的分析,考虑到“行政长官监测框架”中规定的行政长官维度,比使用单一的行政长官执行指标进行更全面的分析。该方法还用于建立可持续发展目标(sdg)实现程度指数,以了解它们与行政长官的关系;CE维度之间的关系;在可持续发展目标之间。按地理区域划分的结果显示,西欧和欧盟15国的CE实施水平较高,根据所考虑的CE维度,卢森堡、奥地利、丹麦、荷兰和比利时轮流位居榜首。因此,新欧洲国家和东方国家必须采取鼓励措施,改善经济的实施。此外,与可持续发展目标8、9和11的总体CE执行指数和分类指数均存在正相关、强相关和显著相关,与可持续发展目标7和15呈负相关。关键词:循环经济;可持续发展目标;综合指标;这个建议考虑了所有现有的信息,没有遗漏任何看起来不相关的信息,并且使用了客观的权重。结果显示,卢森堡、奥地利、丹麦、荷兰和比利时位居前列。西欧国家和组成欧盟15国的国家是执行CE水平最高的国家。可持续发展目标8、9和11与执行行政长官之间存在明确的关系。特别感谢编辑和匿名审稿人对本文的建议。披露声明作者未报告潜在的利益冲突。本研究由西班牙卡斯蒂利亚-拉曼查大学应用经济I系资助[资助号00421I126]。

ABSTRACTRecent rapid economic and infrastructure growth in India has led to degraded environmental conditions. Congested and densely populated urban areas have seen increased pollution, water pollution, and habitat and biodiversity loss. Urban green spaces (UGSs) are vital for improving such environmental qualities and coping with environmental challenges within cities. UGSs provide numerous tangible and intangible environmental, recreational/social, and economic benefits, also acknowledged as ecosystem services. This study assessed residents’ perceptions of UGSs ecosystem services in Delhi, India. The main objectives were to (1) understand residents’ visiting patterns of UGSs and corresponding socio-economic correlations (2) assess residents’ knowledge and perceptions of ecosystem services and disservices, and (3) ranking of ecosystem services provided by UGSs based on significance to the residents. This study is based on a survey of 620 randomly selected respondents in UGSs throughout the city. Most respondents knew about ecosystem services in UGSs and believed the ecosystem services outweighed any ecosystem disservices. The results also showed the importance of improving urban microclimate and environmental quality was emphasized. Interestingly, ecosystem services like improve mental health and aesthetic beauty rated high. The improvement of wildlife habitat, fresh water, water flow regulation & runoff mitigation and the collection of fuelwood, fruits, honey and medicine were not seen as important by the respondents. Residents more readily recognized UGSs’ direct benefits over the indirect benefits. Awareness of economic benefit was relatively high. Results from this research could help urban planners and developers to consider residents’ perceptions and expectations when designing UGSs.KEYWORDS: Ecosystem servicesEcosystem disservicesSurveyUrban treesUrban forestryParks AcknowledgmentsWe, authors, like to thank everyone who helped and participate in this research.

摘要近年来印度经济和基础设施的快速发展导致了环境状况的恶化。拥挤和人口密集的城市地区出现了日益严重的污染、水污染以及栖息地和生物多样性的丧失。城市绿地(UGSs)对于改善城市环境质量和应对城市环境挑战至关重要。地表生态系统提供了许多有形和无形的环境、娱乐/社会和经济效益,也被认为是生态系统服务。本研究评估了印度德里居民对UGSs生态系统服务的看法。研究的主要目标是:(1)了解居民对uggs的访问模式和相应的社会经济相关性;(2)评估居民对生态系统服务和危害的认识和认知;(3)根据对居民的重要性对uggs提供的生态系统服务进行排名。这项研究是基于对整个城市ugs中随机选择的620名受访者的调查。大多数受访者了解uggs中的生态系统服务,并认为生态系统服务大于任何生态系统损害。研究结果还显示了改善城市小气候和环境质量的重要性。有趣的是,生态系统服务,如改善心理健康和审美美的评价很高。答复者认为,改善野生动物栖息地、淡水、水流调节和径流缓解以及收集薪材、水果、蜂蜜和药品并不重要。居民更容易认识到UGSs的直接效益,而不是间接效益。经济效益意识较高。本研究的结果可以帮助城市规划者和开发商在设计UGSs时考虑居民的看法和期望。关键词:生态系统服务;生态系统损害;调查;城市树木;城市森林公园致谢我们,作者,感谢所有帮助和参与这项研究的人。第一作者也要感谢Chindu Chandran女士、Ishita Mathur女士和Prabhakar先生,感谢他们最初编制问卷。第一作者感谢印度政府为研究工作提供博士奖学金。这组作者还感谢印度大学环境管理学院(USEM)院长Gobind Singh Indraprastha大学提供的研究设施。披露声明作者未报告潜在的利益冲突。本论文的第一作者获得了印度政府大学教育资助委员会颁发的国家计划种姓(NFSC)博士研究奖学金,奖学金编号[201718-RGNF-2017-18-SC- DEL-48200],由印度政府社会正义和赋权部资助。

The improvement of wildlife habitat, fresh water, water flow regulation & runoff mitigation and the collection of fuelwood, fruits, honey and medicine were not seen as important by the respondents. Residents more readily recognized UGSs’ direct benefits over the indirect benefits. Awareness of economic benefit was relatively high. Results from this research could help urban planners and developers to consider residents’ perceptions and expectations when designing UGSs.KEYWORDS: Ecosystem servicesEcosystem disservicesSurveyUrban treesUrban forestryParks AcknowledgmentsWe, authors, like to thank everyone who helped and participate in this research.
