NON-EFFICIENCY OBJECTIVES AND DECISION-MAKING IN WATER RESOURCE DEVELOPMENTS1

ABSTRACT: In spite of the rather large volume of literature suggesting that non-efficiency objectives ought to be incorporated into water resource planning frameworks, little has been done to date. A partial explanation is that when goals are in conflict we have no “objective” criteria upon which to make the trade-offs. Also, there are problems of measuring the degree to which various policy actions lead to achievement of various goals. Nevertheless, this paper argues that given the magnitude of the possible gains from incorporating these considerations, considerable effort to overcome these problems is justified. Accordingly, we outline some procedures for making these trade-offs and suggest an alternative (practical) planning framework.     

DISTRIBUTIONAL IMPACTS OF ENVIRONMENTAL MANAGEMENT: FEDERAL GRANTS FOR WATER POLLUTION CONTROL1

ABSTRACT: The income redistribution effects of waste water treatment grants are estimated for each state participating in five federal programs. Both gross and net effects per state and per capita are discussed. The impact of the tax structure used to finance such grants and the grant formulae are investigated.     

Washing away poverty: Water, democracy and gendered poverty eradication in South Africa

This article discusses ways in which the South African Government and grassroots organizations envisage and implement democracy achieved since 1994 in the field of water resources management. The focus is on the democratic, political and economic freedom and equality in resource rights for poor black women, who are central to poverty eradication. While the new water policy and law provide an enabling framework for achieving these goals, implementation on the ground encounters both new opportunities and constraints. This is illustrated by several cases of establishing South Africa's new water management institutions: catchment management agencies and water user associations. The important nexus between state‐led democratization of water resources management and bottom‐up grassroots movements is also discussed. The article concludes that the Government's affirmative and targeted intervention is indispensable for redressing gender inequalities and eradicating poverty.     

Using public procurement to achieve social outcomes

The use of public procurement to achieve social outcomes is widespread, but detailed information about how it operates is often sketchy and difficult to find. This article is essentially a mapping exercise, describing the history and current use of government contracting as a tool of social regulation, what the author calls the issue of ‘linkage’. The article considers the popularity of linkage in the 19^th century in Europe and North America, particularly in dealing with issues of labour standards and unemployment. The use of linkage expanded during the 20^th century, initially to include the provision of employment opportunities to disabled workers. During and after World War II, the use of linkage became particularly important in the United States in addressing racial equality, in the requirements for non‐discrimination in contracts, and in affirmative action and set‐asides for minority businesses. Subsequently, the role of procurement spread both in its geographical coverage and in the subject areas of social policy that it was used to promote. The article considers examples of the use of procurement to promote equality on the basis of ethnicity and gender drawn from Malaysia, South Africa, Canada, and the European Community. More recently, procurement has been used as an instrument to promote human rights transnationally, also by international organizations such as the International Labour Organisation. The article includes some reflections on the relationship between ‘green’ procurement, ‘social’ procurement, and sustainable development, and recent attempts to develop the concept of ‘sustainable procurement.’     

The Gandhian approach to swadeshi or appropriate technology: A conceptualization in terms of basic needs and equity

This is an examination of the significance of Gandhi's social philosophy for development. It is argued that, when seen in light of Gandhi's social philosophy, the concepts of appropriate technology (A.T.) and basic needs take on new meaning. The Gandhian approach can be identified with theoriginal "basic needs" strategy for international development (Emmerij, 1981). Gandhi's approach helps to provide greater equity, or "distributive justice," by promoting technology that is appropriate to "basic needs" (food, clothing, shelter, health and basic education). Gandhi's social philosophy (Erikson, 1968; Roy, 1985) has been neglected by most development specialists, with only a few exceptions (e.g., Chambers, 1983; Charles, 1983). This analysis attempts to draw out some aspects of M.K. Gandhi's background and his thinking aboutswadeshi (i.e. local self-reliance and use of local knowledge and abilities) andswaraj (i.e. independent development that leads to equity and justice). Gandhi's ideas, which emerged out of an "Indic" meta-cultural background, are based on an emphasis on equity. Gandhi's syncretic Indic background includes a belief in what Bateson (1972), writing about Bali, Indonesia, has called the "steady state." Development activities should be carried out in a phased manner that does not disturb the beneficial aspects of dynamic equilibrium, but that does promote "positive development." A.T. is particularly useful within the context of a basic needs approach to international development because use of A.T. is probably more likely to lead to equitable growth. The "economic growth" strategy, utilizing "advanced technology" (or even "high tech") exclusively, has caused unemployment and has not led to effective "trickle down," much less "high mass consumption." In many developing countries the poorest 20% of the population are worse off in 1990 than they were in 1980. By making use of the "advantage of backwardness" (Veblen, 1966) and viewing development in terms of long-term impacts, a basic needs approach using A.T. is more likely to lead to a positive impact on third world food systems than a pure "economic growth" strategy.Paper presented at the Guelph Ethics & Technology Conference: Workshop on Technology and Ethical Choice in the Food Systems: Agriculture Workshop on The Impact of Agricultural Technology on Third World Food Systems.

Gender aspects of work-related injuries in a Swedish municipality

The purpose of this study was to investigate gender aspects of work-related injuries in a Swedish municipality (population 41,000). All unintentional injuries treated at in- and out-patient facilities were recorded during a period of 1 year. The work-related injuries were mapped out in more detail with the help of standardized and structured surveys via telephone interviews and hospital records. The rate of work-related injuries among the gainfully employed was 33 per 1000. Males were observed to suffer more work-related injuries than females (46 compared to 12 per 1000 gainfully employed persons), and there were gender differences with regard to work-related injuries and injury event patterns. Young men showed the highest rate of injuries. Injuries caused during machine operation were the most common for both males and females, amounting to almost one quarter of all injuries. Injuries caused by falls were most common amongst females in the age groups 15–24 (25%) and 45–64 (28%). More attention should be given to gender aspects of work-related injuries and their prevention.     

Pollution perception: A challenge for intergenerational equity

In this article we extend the recent literature on overlapping generations and pollution by allowing generations to perceive the level of pollution differently than the actual level of pollution. We call this pollution perception. Pollution perception can visualize itself as either a concern for the flow of pollution only, or for the stock, or a combination of both. We derive this extension based on empirical evidence from recent advances in behavioural economics.Pollution perception has not only significant consequences for the steady state levels of pollution and capital, but we also find a qualitative change in the dynamics from similar models without pollution perception [A. John, R. Pecchenino, An overlapping generations model of growth and the environment, Econ. J. 104 (1994) 1393–1410]. Specifically, we derive optimal non-linear dynamics through complex eigenvalues and Hopf or Flip bifurcations for a large set of parameters. This leads to violations of two standard criteria of sustainability, suggesting that pollution perception can be another source of intergenerational inequity.     

基于环境基尼系数的控制单元水污染负荷分配优化研究

将基尼系数这一福利经济学概念引入松花江流域水污染物负荷分配过程,综合考虑水循环的社会-经济-资源-环境因素,从社会经济发展、科技进步水平、水污染治理水平和资源禀赋差异角度出发,遴选出人均GDP、重污染行业总产值比重、人均水污染物产生强度、工业水污染物去除率、生活水污染物去除率、单位国土面积水资源量、国控劣Ⅴ类断面占比7项指标,以COD及NH_3-N负荷为控制因子,辅以贡献系数这一表征外部不公平性参数,构建了以基尼系数为度量标准的流域水污染负荷优化分配模型,并据此制订了松花江流域33个控制单元基于公平性的水污染负荷分配方案。研究表明,2012年松花江流域基于7项指标的基尼系数值均大于0.4,超过了基尼系数合理警戒线,说明流域控制单元间COD及NH_3-N排放在社会经济和资源环境方面存在不公平现象,其中松花江干流和第二松花江流域是不公平性特征最为突出的两个流域。在Lingo模型优化分配得到的2020年流域各单元COD削减方案中,单元21的年削减量最大,为1.82万t/a,单元10的年均削减率最高,达8%;在相应NH_3-N削减方案中,单元21的年削减量及削减率均为最大,分别达到0.08万t/a及8%。     

Regression models to estimate total concentrations of polybrominated diphenyl ethers: data from NHANES 2003–2004

The objective of this study was to develop regression models to estimate the total concentration of polybrominated diphenyl ethers in serum based on the known concentrations of a limited number of congeners. Because of the possible adverse health effects associated with the exposure to polybrominated diphenyl ethers, it is of interest to know their total concentrations. Data from the National Health and Nutrition Examination Survey for 2003–2004 (N = 1859) were used to develop regression models to estimate both wet weight and lipid-adjusted total concentrations. Only the knowledge of three congeners, namely, 2,2′,4,4′-tetrabromodiphenyl ether, 2,2′,4,4′,5-pentadibromodiphenyl ether, and 2,2′,4,4′,5,5′-hexabromodiphenyl ether was required to use these models. Other than the concentrations of these three congeners, age, gender, and smoking status were the only information needed to use these models. Optionally, models were developed that could also use the race/ethnicity of the participants. All models explained more than 98% of the known variability in the observed total concentration levels. Over 98% of the model generated, predicted values were found to be within 5% of the observed values.     

Intergenerational equity and discounting

A standard framework is presented as an underlying model for the discounting debate. Views and proposals for the techniques and rates of discounting are assessed. Alternative modeling frameworks for studying intergenerational equity issues are evaluated with the result that the basic insights they provide do not differ very much. Results from model experiments involving different discount rate proposals show that fudging the discount rate does not lead to efficient climate policy. Three major clusters of opinions are identified regarding the applicability of cost-benefit analysis to the climate change problem and the appropriate discount rate to use. It is concluded that under some very special circumstances the cost-benefit rule should be abandoned and cost-effective strategies implying standard discount rates should be sought to reach clearly defined and justified environmental targets.
