People’s livelihoods in developing countries are often directly dependent on wetlands and watersheds for the provision of food, water, fuel, wood, fibre, and genetic resources. The high rural population density within the Lake Victoria basin is facilitating the rapid conversion of land to settlement and agriculture. These activities have resulted in the depletion of wetland resources to the extent that they cannot replenish naturally, thus threatening the Nyando wetland ecosystem, potential recreational opportunities, and the livelihoods of local communities. This paper, therefore, examines the implication of Nyando wetland utilisation in provisioning ecosystem services. A case study survey design approach was employed for data collection. Both quantitative and qualitative data were collected to answer the study objectives. Stratified random sampling was conducted to collect data from 391 households using a structured questionnaire. An interview guide was also used to collect data from stakeholder representatives at the national and county governmental level, non-governmental organisations, and members of the local community. Descriptive statistics were used to analyse the quantitative data, while qualitative data were analysed through content analysis by ordering distinct themes into similar categories. A land-use change analysis was performed using an unsupervised classification technique. The results show that the local community depends on the wetland for farming, firewood, settlement, roofing and mat-making materials, and fishing for domestic and commercial use. The local community’s increased demand and utilisation of Nyando wetland resources has contributed to a reduction in the size of the wetland and consequently affected the availability of ecosystem services. Thus, sustainable utilisation of the wetland is needed.
发展中国家人民的生计往往直接依赖湿地和流域来提供食物、水、燃料、木材、纤维和遗传资源。维多利亚湖流域的高农村人口密度促进了土地向定居和农业的快速转变。这些活动导致湿地资源枯竭,无法自然补充,从而威胁到Nyando湿地生态系统、潜在的娱乐机会和当地社区的生计。因此,本文研究了Nyando湿地利用在提供生态系统服务中的意义。数据收集采用了案例研究调查设计方法。收集了定量和定性数据来回答研究目标。采用结构化问卷对391户家庭进行分层随机抽样,收集数据。访谈指南还用于从国家和县政府层面的利益相关者代表、非政府组织和当地社区成员那里收集数据。描述性统计用于分析定量数据,而定性数据则通过内容分析进行分析,将不同的主题划分为相似的类别。使用无监督分类技术进行了土地利用变化分析。结果表明,当地社区依赖湿地进行农业、木柴、定居点、屋顶和垫子制作材料,以及家庭和商业用途的渔业。当地社区对Nyando湿地资源的需求和利用增加,导致湿地面积缩小,从而影响了生态系统服务的可用性。因此,需要对湿地进行可持续利用。

Beaches are multidimensional environments, and their management must include the ecological, sociocultural and economic aspects. The continuous occupation of this ecosystem combined with the scarcity of adequate management plans has reduced the quality of coastal sceneries. Therefore, strategies are needed to ensure the perpetuity of resources and delivery of ecosystem services. The objective of this study was to assess the coastal scenery quality at three sandy beaches of Rio de Janeiro, Brazil. A quali-quantitative approach was applied using measurable aspects, considering eight categories as accessibility, water quality, scenic quality, infrastructure, safety and environmental education, based on 67 indicators. The beaches commonly presented higher values for water quality, while environmental education had the lowest ranks, indicating that this category should be prioritised in management strategies. In addition to the low cost of this effective tool for beach management, it is quick to apply, easy to analyse and represents an advancement in important issues about the use of integrative indicators to evaluate coastal sceneries, providing a scientific base that can offer evidence about the main management priorities in areas where coastal tourism has a significant role.
海滩是多层面的环境,其管理必须包括生态、社会文化和经济方面。这种生态系统的持续占用,加上缺乏适当的管理计划,降低了沿海景观的质量。因此,需要制定战略来确保资源的永久性和生态系统服务的提供。本研究的目的是评估巴西里约热内卢三个沙滩的海岸风光质量。在67项指标的基础上,利用可测量的方面,考虑到可及性、水质、景观质量、基础设施、安全和环境教育等八个类别,采用了定性定量方法。海滩的水质通常较高,而环境教育的排名最低,这表明在管理策略中应优先考虑这一类别。除了这种有效的海滩管理工具成本低之外,它应用迅速,易于分析,在使用综合指标评估沿海景观的重要问题上取得了进展,为沿海旅游业发挥重要作用的地区的主要管理重点提供了科学依据。

This study investigates the determinants of efficiency in the energy sectors of China and Singapore. It examines three possible futures for the electricity industry in China and Singapore: business as usual, energy efficiency improvement, and regulation and incentive improvement. A panel dataset was subjected to cross-sectional analysis using data envelopment analysis and Tobit regression. In the last 10 years, the electric power sector has reduced carbon dioxide, sulfur dioxide, nitrogen dioxide, and mercury emission rates by 90%, 88%, and 95%, respectively, as a result of imperatives for the closing of small coal-fired power stations, air emissions regulations and the utilisation of renewable energy initiatives. Finally, it is suggested that the maximum capabilities of such expenditures can only be achieved if they are considered and involved in the project discovery process, rather than just as an add-on to initiatives initially planned as demand initiatives.
本研究调查了中国和新加坡能源部门效率的决定因素。它考察了中国和新加坡电力行业的三种可能的未来:照常营业、提高能源效率、改善监管和激励。使用数据包络分析和Tobit回归对面板数据集进行横断面分析。在过去10年中,由于必须关闭小型燃煤发电站、制定空气排放法规和利用可再生能源举措,电力部门的二氧化碳、二氧化硫、二氧化氮和汞排放率分别降低了90%、88%和95%。最后,有人建议,只有在项目发现过程中考虑并参与这些支出,而不仅仅是作为最初计划的需求计划的附加计划,才能实现这些支出的最大能力。

This paper investigates the relationships between carbon emissions, health outcomes, and economic growth. It has been argued that carbon emissions negatively affect health outcomes, which influences the aggregate productivity of countries. A general equilibrium model is constructed, with health and educational outcomes presented as inputs of human capital. The empirical part assesses the impact of health on economic development using carbon emissions and employs the IV model (2SLS) to avoid potential endogeneity. The analysis uses the data of 178 worldwide countries from 2010 to 2016. The findings suggest substantial effects of health as an input of human capital on per capita income. The results form the basis of important policy recommendations for policy- and decision-makers to increase the stock of human capital and sustainable economic growth.
本文研究了碳排放、健康结果和经济增长之间的关系。有人认为,碳排放对健康结果产生负面影响,从而影响各国的总生产率。构建了一个一般均衡模型,将健康和教育成果作为人力资本的投入。实证部分使用碳排放来评估健康对经济发展的影响,并采用IV模型(2SLS)来避免潜在的内生性。该分析使用了2010年至2016年全球178个国家的数据。调查结果表明,作为人力资本投入的健康对人均收入有重大影响。研究结果为政策制定者和决策者提供了重要的政策建议基础,以增加人力资本存量和促进可持续的经济增长。

Accurate implementation of eco-innovation in Sub-Saharan Africa (SSA) to mitigate climate change and related environmental turmoil emanating from economic activities is always ignored. The study seeks to investigate the role of eco-innovation in enhancing environmental sustainability; the effect of eco-innovation on carbon dioxide (CO[Formula: see text] emissions for the aggregated Sub-Saharan Africa panel of 35 countries and low-income and middle-income countries sub-panels over the period 1990–2017 is investigated. Bearing in mind the potential occurrence of residual cross-sectional reliance and heterogeneity, this extant study employed second-generation estimation approaches which include the cross-sectional Im, Pesaran and Shin and the cross-sectional augmented Dickey–Fuller unit root tests together with the Westerlund and Edgerton as well as the Durbin–Hausman panel cointegration tests. The augmented mean group long-run estimation method was finally employed to estimate the long-run liaison amid variables. Based on the outlined robust approaches, the main outcomes are elaborated as follows: (i) eco-innovation significantly reduces environmental pollution in all the panels Sub-Saharan Africa; (ii) income is revealed to have insignificant effect on environmental pollution across all panels, although a positive effect occurred in both the middle-income panel and aggregated panel, whereas an adverse effect is noted in the low-income panel of SSA nations; (iii) energy consumption and urbanisation contribute to environmental pollution in all the panels; (iv) trade openness contributes significantly to environmental pollution in the SSA aggregated panel but has insignificant effect in the sub-panels; and (v) foreign direct investment has no effect on carbon emissions among all panels. The findings also reveal invalid environmental Kuznets curve hypothesis in the various country groups. Based on the findings, we recommend a solid policy framework for investments in more innovation activities that facilitate sustainability transition, prioritise green investments, reduce the importation of emissions-intensive technologies and encourage green production processes which in turn could guarantee sustainable development.
在撒哈拉以南非洲(SSA)准确实施生态创新,以缓解经济活动引发的气候变化和相关环境动荡,一直被忽视。该研究旨在调查生态创新在增强环境可持续性方面的作用;生态创新对二氧化碳(CO)的影响[公式:见正文]对1990-2017年期间由35个国家组成的撒哈拉以南非洲综合小组以及低收入和中等收入国家小组的排放量进行了调查。考虑到剩余横截面依赖和异质性的潜在发生,这项现有研究采用了第二代估计方法,包括横截面Im、Pesaran和Shin,横截面增广Dickey–Fuller单位根检验,以及Westerlund和Edgerton以及Durbin–Hausman面板协整检验。最后采用增广均值群的长期估计方法来估计变量之间的长期联系。根据所概述的强有力的方法,主要成果阐述如下:一生态创新大大减少了撒哈拉以南非洲所有小组的环境污染;(ii)收入对所有面板的环境污染影响不大,尽管中等收入面板和汇总面板都产生了积极影响,而撒哈拉以南非洲国家的低收入面板则出现了不利影响;(iii)能源消耗和城市化导致所有面板的环境污染;(iv)贸易开放对SSA聚合面板中的环境污染有显著贡献,但对子面板的影响不大;以及(v)外国直接投资对所有面板的碳排放没有影响。研究结果还揭示了不同国家群体中无效的环境库兹涅茨曲线假说。根据研究结果,我们建议为更多创新活动的投资制定一个坚实的政策框架,以促进可持续性转型,优先考虑绿色投资,减少排放密集型技术的进口,并鼓励绿色生产流程,从而保证可持续发展。

Sustainability assessment at a national scale is a complex task that ought to be seen with a range of conflicting indicators and multicriteria analysis (MCA) is the best approach that can address these conflicts. The study aims for a comprehensive sustainability assessment of renewable energy (RE) technologies in India based on MCA and examines the impact of associated social and environmental risks on the overall sustainability ranking. Large hydropower is evaluated as the most sustainable RE technology in context to India under selected indicators. Contrary to this, large hydropower has also been identified with the highest social and environmental risks. Therefore, in a developing country like India, the techno-economic advantages of large hydropower with its significant untapped potential cannot be overlooked. Hence, there arises a need to enhance the environmental impact assessment (EIA) process. Thus, the study recommends a transparent process for public participation in EIA for comprehensive and effective social and environmental risk management of the project to achieve the goal of sustainable development.
国家层面的可持续性评估是一项复杂的任务,应该用一系列相互冲突的指标来看待,多标准分析(MCA)是解决这些冲突的最佳方法。该研究旨在基于MCA对印度可再生能源(RE)技术进行全面的可持续性评估,并考察相关社会和环境风险对整体可持续性排名的影响。根据选定的指标,大型水电被评估为印度最可持续的可再生能源技术。与此相反,大型水电也被认为具有最高的社会和环境风险。因此,在印度这样的发展中国家,大型水电的技术经济优势及其巨大的未开发潜力不容忽视。因此,有必要加强环境影响评估程序。因此,该研究建议公众参与环境影响评价的透明程序,以便对项目进行全面有效的社会和环境风险管理,以实现可持续发展的目标。

This research aimed to identify the factors that influence farming households’ decisions on adaptation strategies and the highest priority strategy in South-Western coastal Bangladesh. Seven unions in Koyra Upazila were surveyed, and 60 households were interviewed from each union. The binary logit and multinomial logit models were used to analyse the data. The findings indicate that 58.6% of farming households adopted climate-related adaptation strategies, with seasonal migration being the most top priority. Similarly, the data suggested that years of education of the household heads, number of household members, land tenure, farming experience, climatic event risk perception, and farmer-to-farmer extension influenced both farming households’ adaptation decisions and the likelihood of choosing the highest priority adaptation strategies. Public–private partnerships (PPPs) can integrate funds, knowledge, and power structures. It can also balance expenses, liabilities, and opportunities. So, the development of PPPs may promote suitable adaptation strategies.
这项研究旨在确定影响孟加拉国西南沿海农户适应战略和最高优先战略决策的因素。对Koyra Upazila的七个工会进行了调查,每个工会采访了60户家庭。使用二元logit和多项式logit模型对数据进行分析。调查结果表明,58.6%的农户采取了与气候相关的适应策略,季节性移民是最优先考虑的问题。同样,数据表明,户主的教育年限、家庭成员数量、土地保有权、农业经验、气候事件风险感知和农民对农民的扩展都会影响农业家庭的适应决策和选择最优先适应战略的可能性。公私伙伴关系可以整合资金、知识和权力结构。它还可以平衡开支、负债和机会。因此,发展公私伙伴关系可以促进适当的适应战略。

The Role of Social Impact Assessment (SIA) in the Development of a Mine Closure Plan in Regional Australia 社会影响评估(SIA)在制定澳大利亚区域关闭矿山计划中的作用
Q1 Social Sciences Pub Date : 2022-05-14 DOI: 10.1142/s1464333222500156

Mine closure is an integral part of the lifecycle of a mining project. The closure of a mine has social impacts on the surrounding community and employees who have gradually become dependent on the mine financially, culturally and emotionally. By recognising the consequences of mine closure on local communities, companies respond to the assessment and management of the social impacts. While there are applications of social impact assessments (SIAs) for areas available in different sectors, there are limited practices of SIA for mine closure planning, and there is a lack of information on the role of SIA in mine closure planning. Importantly, there is a dearth of information on how SIA can play an important role to make a mine closure plan by bringing all stakeholders together. This empirical study investigated the contribution of SIA on the development of a coal mine closure plan in regional Queensland in Australia. By integrating social issues and community concerns into the closure planning process, through SIA of the closure planning, the mining company, its employee and the local community were collectively able to formulate the mine closure. This study shows how the SIA can be used to bring relevant stakeholders together to formulate the plan for mine closure and make it acceptable to the stakeholders including company, local communities and employees. Practical policy implications include community engagement through SIA and an assurance of the socioeconomic security of the local community and employees of the mine. It is crucial to undertake SIA at the beginning of the closure planning process and involve the relevant stakeholders to formulate closure plan acceptable to all relevant parties. For the development of a mine closure plan, particular attention is required to address the community’s concerns and the development of a solid relationship with the community through negotiations. It is expected that the findings of this study will be useful to researchers, practitioners and other interested persons, not only in Australia but also in other countries with a similar context.
矿山关闭是矿山项目生命周期的重要组成部分。煤矿的关闭会对周围的社区和雇员产生社会影响,他们逐渐在经济、文化和情感上依赖煤矿。通过认识到煤矿关闭对当地社区的影响,企业对社会影响的评估和管理做出了回应。虽然社会影响评价在不同部门的可用地区有所应用,但是社会影响评价在关闭矿山规划方面的做法有限,而且缺乏关于社会影响评价在关闭矿山规划中的作用的资料。重要的是,缺乏关于SIA如何通过将所有利益相关者聚集在一起,在制定矿山关闭计划方面发挥重要作用的信息。本实证研究考察了SIA对澳大利亚昆士兰地区煤矿关闭计划制定的贡献。通过将社会问题和社区关注的问题纳入关闭计划过程,通过关闭计划的SIA,矿业公司、其雇员和当地社区能够共同制定矿山关闭计划。本研究展示了如何利用SIA将相关利益相关者聚集在一起制定矿山关闭计划,并使其为包括公司,当地社区和员工在内的利益相关者所接受。实际的政策影响包括通过SIA进行社区参与,并确保当地社区和矿山员工的社会经济安全。在关闭计划过程的开始就进行SIA,并让相关利益相关者参与制定所有相关方都能接受的关闭计划是至关重要的。为了制订一项关闭地雷计划,必须特别注意解决社区的关切问题,并通过谈判与社区建立牢固的关系。预计本研究的结果将对研究人员、从业人员和其他感兴趣的人有用,不仅在澳大利亚,而且在其他具有类似背景的国家。

Strategic environmental assessment (SEA) has the potential to play a crucial role in addressing global food insecurity. This paper presents the results of an evaluation of 17 recent Canadian SEAs, conducted for offshore petroleum exploration, exploring the extent of consideration for food security in current SEA practice. Document analysis was used to appraise consideration of eight core food security elements and conformity to procedural and analytical elements recommended for effective food security assessment in regional SEA. Performance variation among the SEAs in was observed. Notable deficiencies include lack of explicit consideration for food security and lack of transparency around public participation, as well as limited characterisations of the socio-political environment. Some encouraging findings, however, suggest that food security can be successfully addressed in regional SEA. In particular, the ‘system analysis’ approach typically employed in SEA in the offshore petroleum exploration industry is well-suited to food security assessment. Certain aspects of food security are already indirectly considered and incorporated in SEA; yet, there is considerable scope for improvement of integrating food security effectively in SEA.
战略环境评估(SEA)有可能在解决全球粮食不安全问题方面发挥关键作用。本文介绍了对加拿大最近17个海上石油勘探SEA的评估结果,探讨了当前SEA实践中对粮食安全的考虑程度。采用文献分析的方法,评价了对8个核心粮食安全要素的考虑,以及是否符合区域SEA建议的有效粮食安全评估的程序和分析要素。观察到不同sea的性能差异。值得注意的不足包括缺乏对粮食安全的明确考虑,公众参与缺乏透明度,以及对社会政治环境特征的有限描述。然而,一些令人鼓舞的发现表明,粮食安全可以在区域东南亚成功解决。特别是,海上石油勘探工业中SEA通常采用的“系统分析”方法非常适合粮食安全评估。粮食安全的某些方面已被间接考虑并纳入战略评估;然而,在将粮食安全有效地纳入东南亚战略方面仍有相当大的改进空间。

Economic Impacts of Carbon Tax in a General Equilibrium Framework: Empirical Study of Japan 一般均衡框架下碳税的经济影响:日本的实证研究

This study tries to find new insights of implementations of carbon tax policy as a suitable way to reach the long-term zero-carbon plan. This paper explores how carbon tax can affect the macroeconomy in Japan through the structural vector autoregression (S-VAR) technique conducted for the quarterly data throughout 2005–2020. A theoretical general equilibrium model backs the empirical analysis. The major findings reveal that any increase in energy price from the carbon tax will lead to an increase in interest rate, exchange rate, and consumer price index while there is a negative relationship between energy price increase from carbon tax and real gross domestic product (GDP) in Japan. Carbon Policy Refolution ([Formula: see text]), refunding carbon tax revenues, and adaptation of long-term policy of net zero GHG emissions by 2050 with the current situation of Japan’s power sectors are the major practical policies of this study.
本研究试图寻找碳税政策实施的新见解,作为实现长期零碳计划的合适途径。本文通过对2005-2020年季度数据进行的结构向量自回归(S-VAR)技术,探讨了碳税如何影响日本的宏观经济。理论一般均衡模型支持实证分析。研究发现,碳税导致的能源价格上涨将导致利率、汇率和消费者价格指数的上升,而碳税导致的能源价格上涨与日本实际国内生产总值(GDP)呈负相关关系。碳政策革命([公式:见文])、碳税收入退还、2050年温室气体净零排放长期政策与日本电力行业现状的适应是本研究的主要实践政策。
