矿产资源开发区水污染经济损失实证研究——以甘肃省庆阳市为例

运用修正的人力资本法和市场价值法估算了庆阳市水污染引起的对人体健康经济损失和对农业的经济损失,并在广泛收集资料的基础上估算了工业经济损失和城市供水与水环境污染的治理成本损失.庆阳市2007年水污染经济损失达45225.45万元,水污染情况较严重.其中,水污染对人体健康损失和对工业损失的影响较大,对农业损失和对城市供水与水环境污染治理成本损失的影响相对较小.鉴于部分数据没有直接相关的统计资料以及计算中的保守性,其经济损失数据可视为庆阳市水污染经济损失的下限值.     

成渝地区大气污染生命统计价值评价研究——基于单边界二分式的条件价值法

大气污染生命统计价值是进行大气污染造成的人体健康损失核算和大气污染防治政策成效评估的关键指标。本文运用条件价值方法的单边界二分式函数模型,对成渝地区降低大气污染健康风险的平均支付意愿和生命统计价值进行了计算。主要结论如下:①成渝地区大气污染的平均支付意愿是1974.2元,生命统计价值为394.8万元。其中,四川部分地区和重庆地区的生命统计价值分别为402万元和392.8万元。②性别、家庭年收入和自我认知的身体健康状况等指标对平均支付意愿影响较大。③在生命价值评估方法中,国内普遍使用人力资本法,而国外主要使用条件价值法。条件价值法计算的生命统计价值高于人力资本法计算的结果,但与发达国家相比,我国成渝地区的生命统计价值相对较低。

国家《大气污染防治行动计划》健康效益评估

为了提高空气质量改善进程,2013 年国家发布了《大气污染防治行动计划》。本文基于空气污染与健康效益评估模型(BenMAP),对人口分布资料、大气污染与人体健康影响的暴露反应关系等进行了本土化修正,采用“支付意愿法”与“疾病成本法”相结合的方法,系统评估了《大气污染防治行动计划》实施后,PM_2.5 污染变化引起的环境健康效益。研究结果表明,《大气污染防治行动计划》的实施将在一定程度上降低PM_2.5 环境浓度,改善环境空气质量。如果《大气污染防治行动计划》空气质量目标全面实现,可以避免城镇8.9 万居民的过早死亡,减少12 万人次住院治疗以及941 万人次的门诊和急诊病例,实现的全国健康效益约为867 亿元/ 年,说明了《大气污染防治行动计划》实施的健康有益性。本文对政府部门开展污染损失评估及制定环境健康政策具有重要的参考价值。     

区域环境污染造成的经济损失估算——以银川市为例

通过研究银川市的环境监测资料、国民经济统计资料等,借鉴与银川市实际情况比较符合的参数,运用人力资本法、市场价值法、土地价值损失法、收益还原法、机会成本法等环境经济学方法,以2009年为例估算了大气污染、水污染、固体废弃物污染、噪声污染对银川市造成的经济损失。初步估算出银川市2009年因环境污染造成的直接经济损失为45.279亿元,环境污染状况严峻,城市环境保护成为银川市经济可持续发展的基础。     

《大气污染防治行动计划》实施的投融资需求及影响评估

当前我国大气污染形势严峻,严重损害人民群众身体健康,影响社会和谐稳定。为切实改善空气质量,国务院于2013年9月印发了《大气污染防治行动计划》(简称《行动计划》)。本研究测算了实施该行动计划所需投入资金,并定量评估了可能给中国带来的社会、经济、健康等影响。结果表明,《大气污染防治行动计划》直接投资共计需要资金约1.84万亿元,其中优化能源结构、移动源污染防治、工业企业污染治理、面源污染治理的投资需求约分别为2844亿元、14 067.66亿元、915.44亿元和615.72亿元;2017年全国因实施《大气污染防治行动计划》而减少的慢性死亡人数平均约为11.06万人,占人口总数的0.15‰,各地损失寿命年限均有所下降,即寿命有延长趋势;带来的社会经济影响为正效应,在2013—2017年,计划的实施将拉动我国GDP增长约20 403.01亿元,增加就业岗位约291.13万个。本研究对政策评估研究及未来大气污染治理发展方向具有重要参考价值。

利用衡水市环境监测站2005—2007年度大气例行检测的数据，对衡水市大气中主要污染物SO^2、NO^2、PM10体积质量值的逐日数据进行统计分析，得出了衡水市空气污染的现状和时间变化规律：（1）污染物体积质量值的月变化曲线呈槽型分布，非取暖期的空气状况明显好于取暖期，取暖期SO^2平均体积质量是非取暖期的2．45倍；（2）污染物体积质量值的日变化曲线基本为两高两低型，其中取暖期污染指数早晨出现极高值的时间比非取暖期明显偏晚；（3）污染物体积质量值的年变化表明了SO^2的体积质量在降低，而NO^2的体积质量却有了小幅增长。     

Measuring the gains from improved air quality in the San Joaquin Valley

Many regions worldwide are experiencing rapid urbanization, and often along with growth in the local economy and population comes worsening air quality. Such regions typically find that addressing the additional challenge of polluted air is difficult. This paper reports the results of an assessment of the present health and related economic costs of poor air quality in the San Joaquin Valley of California. Further, it suggests how such assessments can support strategies to pursue pollution reductions that offer the largest near-term gains, by rigorously modeling the associations between pollution levels, demographic groups, and recognized adverse health effects.

Mortality and morbidity benefits of air pollution (SO2 and PM10) absorption attributable to woodland in Britain

Forests in Britain produce social and environmental benefits, in addition to marketable timber outputs. One such non-market benefit is the reduction in air pollution, linked to health impacts (mortality and morbidity). This study assesses the benefits of SO2 and PM10 absorption by trees in terms of extending life expectancy of the population and reducing hospital admissions. Working at a resolution of 1 km2 with woodland over 2 ha, it is estimated that, for Britain as a whole, woodland saves between 5 and 7 deaths, that would otherwise have been brought forward, and between 4 and 6 hospital admissions each year. The economic value of the health effect of woodland is estimated to be at least 900,000 pounds Sterling per year. Smaller areas of woodland, often located closer to population, sometimes strategically planted close to pollution sources, will generate additional air pollution absorption benefits to those estimated here. Researching such benefits would require more detailed data than is available at present for a national study. However, the health benefits of woodland are relatively small in comparison to other non-market forestry benefits.     

Continuing Issues in the Limitations of Pesticide Use in Developing Countries

The rationale for pesticide use in agriculture is that costs associated with pesticide pollution are to be justified by its benefits, but this is not so obvious. Valuing the benefits by simple economic analysis has increased pesticide use in agriculture and consequently produced pesticide-induced “public ills.” This paper attempts to explore the research gaps of the economic and social consequences of pesticide use in developing countries, particularly with an example of Nepal. We argue that although the negative sides of agricultural development, for example- soil, water, and air pollution; pest resistance and resurgence; bioaccumulation, bio-magnification; and loss of biodiversity and ecosystem resilience caused by the use of pesticides in agriculture, are “developmental problems” and are “unintentional,” the magnitude may be increased by undervaluing the problems in the analysis of its economic returns. Despite continuous effort for holistic system analyses for studying complex phenomena like pesticides impacts, the development within the academic science has proceeded in the opposite direction that might have accelerated marginalization of the third world subsistence agricultural communities. We hypothesize that, if these adversities are realized and accounted for, the benefits from the current use of pesticides could be outweighed by the costs of pollution and ill human health. This paper also illustrates different pathways and mechanisms for marginalization. In view of potential and overall negative impacts of pesticide use, we recommend alternative ways of controlling pests such as community integrated pest management (IPM) along with education and training activities. Such measures are likely to reduce the health and environmental costs of pesticide pollution, and also enhance the capabilities of third world agricultural communities in terms of knowledge, decision making, innovation, and policy change.     

Industry's role in air quality improvement: Environmental management opportunities for the 21st century

More than 200 years ago, Adam Smith, the founder of modern economics, wrote in the Wealth of Nations that “…consumption is the sole end and purpose of all production; and the interest of the producer ought to be attention to…that of the consumer.” In recent years, the rapid growth of the world economy has given Adam Smith's maxim new meaning. The age-old desire for consumption grows unabated and increasing numbers of consumers around the world are attaching new value to the environmental quality of goods and services and expressing concern over the environmental impacts of industrialization. That concern is growing because more than 70 percent of the world's urban population live in areas where the air is seriously polluted and as many as 750,000 people—the majority in developing countries—die each year of ailments caused by air pollution.¹ Over the past 25 years, corporations throughout the world have made dramatic changes in the way they do business as more people come to understand how the ecological system works and how polluted air and water endanger human health. The key to increasing industry's participation in the drive for higher standards of air quality is the growing realization that effective environmental management, technological development, and technology dissemination are cost-effective and profitable business strategies. Global competition is making firms around the world more customer-conscious and, to the extent that consumers demand products that minimize environmental degradation and enhance the quality of their lives, businesses in every industry must respond in order to survive.² This article examines how changes in business practices, driven by a better understanding of how natural environments function, are converging to provide new opportunities for environmental management that go beyond regulatory compliance to reduce air pollution. Although sound and well-enforced environmental regulations are an essential foundation for improving air quality, command-and-control systems alone are unlikely to achieve the lower levels of pollution that will be necessary to achieve sustainable development in the 21st century. In cooperation with government, businesses in every industry can play crucial roles in achieving higher standards of air quality while at the same time maintaining acceptable levels of economic growth. We explore three ways in which corporations can contribute to environmentally sustainable development: (1) by adopting proactive environmental management systems that focus on air pollution prevention; (2) by developing new technologies for air pollution control and reduction; and (3) by transferring air pollution control and prevention technologies through international trade and investment.
