Effect of lifestyle changes and consumption patterns on environmental impact: a comparison study of Pakistan and China

Increased economic development and industrialization put strain on environment, hence causing pollution and destroying ecosystem. Generally, many different factors affect the environment. These factors include GHG emissions, deforestation, and others. These are all related to human activities on Earth. Other factors that affect environment include population, consumption patterns, and changing life styles of people due to increased income. This study involves the comparison analysis of Pakistan and China on the basis of environmental impact caused by some major driving factors. China is the second largest CO₂ emitter in the world with a population of 1.37 billion in 2016 and the second largest economy in the world. Pakistan is ranked as 40th on the basis of nominal GDP. Both the countries observed noticeable growth in economic development for over 55 years, i.e. 1960–2016. This study identifies how population, affluence, consumption, and emissions as the major factors affect environmental pollution and use ImPACT equation, or I = PACT, to calculate the environmental impact and to determine which factors affect the environment the most. The study suggests that the people of both China and Pakistan have experienced increased income for the past 50 years and this increase has led to the changes in their lifestyles, from suitable clothing and quality food to comfortable living and increased energy consumption, thus affecting environment.     

The environmental impacts of regional disparity in population and wealth distribution in Nigeria

The disparity in both population and wealth distribution in Nigeria by geo-political zones is well recognized. There is also the recognition that some of the environmental problems in certain sections of the country can be attributed to the imbalance in both population and wealth distribution. Hence the various agitations for environmental resource control in the country. What is lacking however is the research that shows the magnitude of the linkages between the disparity and the environmental degradation in regional context. This provides the basis for this research. To achieve the aim of the research, a STIRPAT model was employed as an analytical tool. The findings show that the southern geopolitical zones are generally more densely populated and wealthier than the northern zones. The south is also experiencing a higher degree of environmental resource degradation attributable to anthropogenic factors. Thus, there is congruence between population density, wealth distribution and environmental degradation in Nigeria. Therefore the achievement of sustainable environment and development in Nigeria requires deliberate policies to mitigate the impact of population concentration and wealth creation on the environment.

Floating Population Increase and Its Influence on the Urban Population Situation: A Case Study in Beijing

Abstract

Floating population is a special population group in China resulting from the implementation of household registration system. This paper uses a set of floating population survey data, population censuses data and statistical data to analyze the increase and influence of floating population on the urban population situations in Beijing. It is found that Beijing has experienced a rapid increase of floating population since the 1990s and that the increase of this group has become the key factor of the current population expansion in the city. Its distribution in the urban regions intensified and extended the suburbanization process of the capital. In addition, the population structures of sex, age, education and employment in Beijing have changed to some extent due to the influx of floating population.     

Putting consumers first in design for sustainable behaviour: a case study of reducing environmental impacts of cold appliance use

To slow down the increasing environmental degradation, design for sustainable behaviour (DfSB) has emerged in sustainable design aiming to promote behavioural change through design innovations to reduce environmental and social impacts from the demand side or consumer side. This paper presents a practice-based journey to investigate the process and results of the application of social-psychological theories into sustainable design. Focusing on the behaviour-related impacts of products and services during the use stage, a Design Behaviour Intervention Model (DBIM) is developed through the analysis and synthesis of the social-psychological theories and behaviour-changing strategies. The DBIM indicates that an in-depth study of consumer behaviour is the preliminary step in DfSB, which determines the application of design strategies and potentially the effectiveness of design interventions. A case study is presented to demonstrate the application of the model. The results show that consumer behaviour insights offer rich resources to assist designers in sustainable design innovation. Product-based design suggestions and a proposed solution highlight that the application of DBIM coupled with consumer involvement throughout the design process could produce desirable and sustainable patterns of household fridge use. Finally, the structured consideration of behavioural change and their possible application in DfSB are discussed.     

环境财税政策的治污效应研究——基于区域和门槛效应视角

首先参照投入—产出比,利用环保财政投入占GDP比重与环境污染综合指数之比对各区域环境财政政策治污效应系数进行测算,按系数值域把中国30个省(市)分成两个区域,区域1包括北京、甘肃、贵州等19个省市,区域2包括上海、浙江、福建等11个省市。其次分析环境财政政策、环境税收政策和中国式环境分权的治污效应并分区检验,最后对中国式环境分权和经济发展水平的门槛效应进行实证检验。结果表明:环境财政政策治污效应显著,区域1财政政策取得了更好的治污效果,中国目前车船税、城市维护建设税、土地使用税、耕地占用税、资源税及排污费等"近似"环境税种总体治污效应不显著,中国式环境分权与污染物排放显著正相关,中国式环境分权和经济发展水平对财政政策的治污效应具有显著的门槛效应,当中国式环境分权度低于-0.164、经济发展水平低于4.174时,环境财政政策具有更好的治污效果。样本期内以中国式环境分权为门槛变量时,有安徽、广西等15%的观测值位于低门槛区域,以经济发展水平为门槛变量时,有贵州、云南等10%的观测值位于低门槛区域。中国目前的能源消费结构和工业结构是加剧环境污染的重要原因,城镇化和对外开放在一定程度上助推了高污染和高排放。鉴于此应加大环境保护财政支出,提升环保财政支出占GDP的比重,单独开征环境保护税种,中央政府适度地环境集权,全面提升环境质量。     

环境司法专门化视阈下环境法庭之检视与完善

随着环境问题日益凸显,我国积极推进环境司法专门化进程,从最高人民法院到基层人民法院初步形成了具有中国特色的环境法庭体系。这一体系由环境保护审判庭、环境保护合议庭、环境保护巡回法庭以及为数不多的基层环境保护派出法庭构成。目前的环境法庭主要采用三加一模式、三合一模式、二合一模式以及单一模式等四种审理方式,在缓解环境案件审判压力、公正审理环境案件、推进环境公益诉讼、提高环境司法水平等方面发挥了一定的作用。但同时亦应注意到,现有的环境法庭存在诸多问题:基层人民法院缺少法定权限,中级以上人民法院缺少设立环境法庭的程序性依据,致使法律依据不足;缺乏合理的机构建制,级别管辖和地域管辖制度不甚科学;受案范围有限和受害者起诉意愿不足,致使案源不足;特别程序缺失,监测评估机构缺乏中立性,审判人员专业性不强,致使支持保障机制不健全。为此,应从如下几个方面完善我国的环境法庭:首先,为环境法庭建设提供明确的法律依据,规范环境法庭的设立、职责定位及基本权限等事项,将环境法庭建设全面纳入法制轨道;其次,健全环境法庭体系,着重健全环境法庭审级设置,同时完善地域管辖;再次,改进审判模式,健全多审合一程序;再次,拓宽案件来源,合理确定环境公益诉讼的起诉主体,扩大受案范围,完善鼓励起诉机制;最后,完善支持保障机制,针对一审程序设立专业陪审员,针对二审程序设立专家委员会。     

Urban development,environmental vulnerability and CRZ violations in India: impacts on fishing communities and sustainability implications in Mumbai coast

Coastal Regulations in India are traced back to the UN Conference on Human Environment, held in Stockholm in 1972. The Environment Protection Act (EPA) 1986 was enacted to implement India’s commitments as a signatory. The Coastal Regulation Zone (CRZ) Notification of 1991 was made under the provisions of the EPA in order to protect coastal environments and social and livelihood security of fishing community. This paper assesses the effects of CRZ rules and violations in the Mumbai Metropolitan Region, which has experienced tremendous growth due to the rapid industrialization and urbanization. This process has led to the destruction of mangroves and other important species of fish which play a crucial role in sustaining the coastal ecology and urban biodiversity; high population density and uneven growth have exacerbated adverse environmental and socioeconomic consequences. The Koli (fishing community) in this region faces huge problems of survival and sustenance in small-scale fishing, due to the rampant commercial fishing by big trawlers and large-scale dumping of waste materials by the industries surrounding the vicinity into the sea. In small but significant ways, the fishing communities through their traditional commons-based resource management and livelihood systems protect the coastal ecology and help the cities in reducing their carbon footprints. On the basis of primary field research in Thane–Mulund Creek Bhandup, Chimbai, and Sewri, this paper attempts to assess CRZ violations taking place on coastal areas and is causing damage to the coastal ecology. The research specifically has focused on the particular fishing-related activities and spaces—such as: jetties, parking of boats, access to sea, weaving and drying of nets, landing grounds, drying and cleaning of fish that are more affected by encroachment of seashore area and by CRZ rules violations. It evaluates the actions taken by Maharashtra Coastal Zone Management Authority and Bombay Municipal Corporation while implementing rules and making Integrated Coastal Zone Management plan for management of marine environment. It raises broader issues relating to the contradictions and complementarities involved in ICZM plans vis-a-vis management of biodiversity, within a larger context of rapid urbanization and demands for real estate growth. The paper argues that urban biodiversity management requires clear valuation of the long-term ecological and socioeconomic benefits of sustenance of coastal ecology and related livelihoods.     

Population, environment and poverty in Pakistan: linkages and empirical evidence

This study explores the interlinkages among population, environment and poverty and presents empirical evidence in a developing country like Pakistan. It gives alternative views on population environment linkages. It explains poverty trap, market based harmony, and dual effect of poverty on the basis of a link between population growth and natural resource degradation. In addition, the paper also highlights social and political instability through population-poverty-environment spiral. It also presents empirical evidence on population-environment-poverty nexus in Pakistan. It also compares environmental sustainability index and human development index for selected Asian countries. The paper also gives scores for different components of environmental sustainability index for Pakistan and compares these with India. The paper concludes that the causal relationship between poverty and environment works in both directions, often through changes in GDP and population. Population stress does not have any significant direct effect on all aspects of environmental status in Pakistan.

Review,assessment and recommendations on environmental policies in Western China

Reviewing the existing environmental policies in Western China,we find that:in time sequence,the characteristics of China's western environmental policies shift from"development drive governance"to the full implementation of environmental protection and construction;and in spatial sequence,the ecological,social,and economic development of Western China reach to coordination through the nature reserve setting,ecological migrants,fiscal transfer payment and differentiated ecological environmental policies.Due to the implementation of the policies and projects,environmental degradation trends in the western ecological environment were alleviated significantly,the living conditions of farmers and herdsmen were improved,and many successful experiences were explored.However,future ecological environmental construction in Western China requires further improvement in integrated planning,eco-compensation mechanism,and policy assessment.This paper concludes with specific recommendations such as drawing up ecological environment construction planning,strengthening environmental law enforcement and incentive mechanisms,improving policy assessment and scientific support,enhancing environmental protection capacity,improving eco-compensation mechanism,and refining the environmental policies for key areas.     

Polychlorinated dibenzo-p-dioxins and dibenzofurans pollution in China: sources, environmental levels and potential human health impacts

This review represents an assessment of the pollution status of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in China (the mainland, Hong Kong and Taiwan). During the past decades, seven PCDD/Fs pollution hotspots have been found: (a). Ya-er Lake, Hubei Province, with 'total PCDD/Fs' level reaching 177,427 pg g(-1) (dry weight) in lake sediments; (b). Chinese Schistosomiasis affected areas of Jiangxi Province with 33,660 pg g(-1) in soil; (c). e-waste recycling area of Yangtze River Delta, with 2726 pg g(-1) in paddy soil; (d). e-waste recycling area of Guiyu (eastern part of Guangdong Province), with 967,500 pg g(-1) in mixture of burnt residue and soil (the highest level among all hotspots); (e). Pearl River Delta with 2630 pg g(-1) in coastal sediment. (f). Kwun Tong, Victoria Harbour, Hong Kong with 10,999 pg g(-1) in coastal sediment; and (g). southern Taiwan with 606,000 pg g(-1) in soil near the vicinity of a pentachlorophenol manufacturing factory. The main sources of PCDD/Fs in China were formed from impurities during the production of polychlorophenol, hexachlorobenzene, polychlorinated biphenyls, organic chlorinated pesticide and triclosan. In addition, sources of PCDD/Fs included municipal waste incineration, mineral fuel usage, open burning of electronic waste and crop residues, industrial waste discharge and vehicle exhaust emission. Due to potential human health risks from long-term exposure to PCDD/Fs at these hotspots, body loadings of these contaminants should be monitored.     

上市企业环保信息披露与股票投资者社会环境偏好

本文分析了2008—2014年A股市场对强制披露的企业社会责任报告中环保信息的反应,展示了我国股票投资者社会环境偏好的变化过程。虽然近年来我国人均收入已经处于环境库兹涅茨曲线的排放拐点附近,但是目前鲜有国内研究对公众的社会环境偏好变化过程进行分析。本文分三个部分对股票市场投资者的社会环境偏好进行检验:首先,利用事件分析法展示了7年间股票投资者的整体态度,发现由环保信息披露引起的累积超额回报率显著大于零,说明投资者平均持积极态度。其次,使用倾向得分匹配双重差分法检验环境监管政策加强带来的影响,一方面《大气污染防治行动计划》的实施使得投资者态度从负面向正面转变,说明投资者环境偏好受政策影响显著;另一方面《大气污染防治行动计划》的实施显著提高了国有企业环保行为的水平。最后,通过对政策效应的形成机制进行检验发现,我国上市公司的环保行为在投资者眼中并不只是为了完成社会责任信息披露的政策指令而实施,而是股票投资者已经形成社会环境偏好,使得企业具有构建"绿色企业形象"的需求。另外,由于本文的研究对象是强制披露的企业社会责任报告,所以有效规避了西方相关研究中自愿披露导致的自我选择问题,但同时西方学者普遍对我国强制披露的企业社会责任报告所包含的信息持怀疑态度,因此本文通过利用情绪分析程序对环保信息的信息有效性进行检验,结果显示文本情绪的强弱与股票价格波动幅度有正相关关系,说明企业环保信息是投资者决策信息集的一部分,即强制披露的企业社会责任报告包含有效信息。     

基于环境介质的生态底线指标体系构建及考核评价

建立反映维护基本生态系统服务和生态安全的考核指标体系,量化生态环境保护绩效评估,形成环境污染控制和环境质量改善的倒逼机制,对于促进环保目标从单一目标向双目标的实现具有重要的战略意义。文章从解析生态底线的内涵和表征着手,基于环境介质,选取大气、水体、植被、土壤、能源5个方面共17项指标,构成生态底线指标体系的基本框架。提出评估模型和方法,通过测量值与底线值的比较,反映环境保护和生态建设的实际绩效,考虑到各行政区各功能区的生态特点及环境初始状态的差异,引入历史数据进行修正,对单个指标及综合绩效分为优良、改善、恶化、极差四个基本等级进行考核鉴定。不同于以往许多以污染物排放控制作为指标体系的思路和地方实践,所建立的生态底线指标体系更关注生态环境的本底条件,指标测度从常规的过程和终端标准转向自然生态环境的质量状况,有效化解污染排放都达标,但环境质量日益恶化的难题。建议各地结合当地特点明确本地区的生态底线,加强各参与部门的交流协调以提供全面而一致的统计与监测信息,加强信息发布平台的建设等基础工作;处理好底线考核机制与原有年度考核机制的关系,生态底线考核结果与相应的奖惩制度和晋升制度等挂钩,将其作为领导干部选拔任用及"五好"班子评选的重要依据;加强配套制度的建设;建立公众参与的相关机制。     

Climate change and natural disasters: macroeconomic performance and distributional impacts

Commonly occurring natural events become natural disasters when they affect the population through death and injury, and/or through the destruction of natural and physical capital on which people rely for their livelihood and quality of life. Climate change plays a role in that it tends to increase the frequency and intensity of weather-related natural disasters. Additionally, climate change may put people at risk by influencing access to water, coastal flooding, disease and hunger, and leaving them with a more degraded environment, leading, in turn, to increased vulnerability. The purpose of this paper is to present a review and synthesis of the literature and case studies addressing differential impacts of climate change-related natural disasters on a society and its economy. Developed and developing countries show different vulnerabilities to natural disasters. Even within countries, impacts vary significantly across population and economic sectors. When losses from natural disasters are large, their cumulative effect can have notable macroeconomic impacts, which feed back to further pronounce existing income inequalities and lower income levels. Impacts tend to be most pronounced for women, the young and elderly, and people of ethnic or racial minorities.

Comparing environmental product footprint for electronic and electric equipment: a multi-criteria approach

Electronic and electric devices are now applied in most human activities: their diffusion is increasing worldwide; furthermore, most of them are characterized by a high replacement rate due to technological obsolescence. Consequently, environmental problems due to their diffusion are increasing; several aspects are involved from the energy consumption derived from their manufacturing processes and their use phases to their end-of-life (EOL) management. Such legislative (e.g. the European Energy Efficiency directive for household appliances) or voluntary interventions (e.g. based on the ISO standards) have been introduced for such devices: the aim is to incorporate environmental considerations in product design and manufacturing in order to benefit the environment. Some attempts are focusing on defining standardized models for the overall lifecycle including waste management. The aim of this paper is to introduce a reference model for comparing environmental product footprint of electrical and electronic equipment (EEE). All life cycles of EEE will be evaluated: a specific focus is on the EOL management process as their waste management represents a complex problem for developed and developing countries. A multi-criteria decision-making model will be developed based on the well-known analytical hierarchy process (AHP) method: differently from traditional AHP applications, an absolute model has been proposed in order to compare EEE effectively from an environmental point of view. A case study validation regarding large household appliances is proposed.

Debating ecological justice: implications for critical environmental education

This article will briefly discuss the implications of recognition of ecological justice in relation to environmental education (EE) and education for sustainable development (ESD). It is argued that the present conception of environment taught through EE and ESD negates the subjectivity of non-human species and ignores the ethical imperatives of ecological justice. Evocating environmental ethics, major directions integrating ecological justice into EE and ESD are proposed.
