Uncertainty communication in environmental assessments: views from the Dutch science-policy interface

Scientific assessments of environmental problems, and policy responses to those problems, involve uncertainties of many sorts. Meanwhile, potential impacts of wrong decisions can be far-reaching. This article explores views on uncertainty and uncertainty communication in the Dutch science-policy interface and studies several issues concerning presentation of uncertainty information. Respondents considered uncertainty communication to be important, but it should be concise and policy relevant. Several factors influence policy relevance, including the place of an issue in the policy cycle, and its novelty, topicality and controversiality. Respondents held particular interest in explicit communication on the implications of uncertainty. Related to this, they appreciated information on different sources and types of uncertainty and qualitative aspects of uncertainty (e.g. pedigree charts). The article also studies probability terms, particularly for IPCC's 33–66% probability interval (‘about as likely as not’). Several terms worked reasonably well, with a median interpretation of 40–60%. Finally, as various target groups have different information needs and different amounts of attention for various parts of a report or communication process, it is important to progressively disclose uncertainty information throughout the communication. Improved communication of uncertainty information leads to a deeper understanding and increased awareness of the phenomenon of uncertainty and its policy implications.     

The need for ecocentrism in biodiversity conservation

Over the past 5 decades, scientists have been documenting negative anthropogenic environmental change, expressing increasing alarm, and urging dramatic socioecological transformation in response. A host of international meetings have been held, but the erosion of biological diversity continues to accelerate. Why, then, has no effective political action been taken? We contend that part of the answer may lie in the anthropocentric ethical premises and moral rhetoric typically deployed in the cause of conservation. We further argue that it is essential to advance moral arguments for biodiversity conservation that are not just based on perceived human interests but on ecocentric values, namely, convictions that species and ecosystems have value and interests that should be respected regardless of whether they serve human needs and aspirations. A broader array of moral rationales for biodiversity conservation, we conclude, would be more likely to lead to effective plans, adopted and enforced by governments, designed to conserve biological diversity. A good place to start in this regard would be to explicitly incorporate ecocentric values into the recommendations that will be made at the conclusion of the 15th meeting of the parties to the Convention on Biological Diversity, scheduled to be held in October 2020.     

The Concept and Theoretical Implications of Carbon Emissions Rights Based on Individual Equity

Abstract

Climate change has become a hot topic in international environmental negotiations. For post-Kyoto international climate regime negotiations, many countries have proposed a variety of frameworks to share the emission reduction responsibilities and allocate carbon emission rights, and have tried to quantify the emission reduction obligations of all countries based on the perspectives of international equity and individual equity. In this paper, the authors have distinguished the concepts of carbon emissions rights based on these two perspectives respectively, have analyzed the relationship between carbon emissions per capita and economic development, and have calculated and compared the proportion of cumulative emissions per capita of different countries in history and future, and then authors conclude that emission reduction obligations should be allocated based on each country’s conditions, including historical emissions, development stage, and future demands. Developed countries should take the initiative to significantly reduce their emissions because they have already accomplished their industrialization process. However, developing countries are still in the process of industrialization, which requires more emission rights to meet their development needs. For China, the concept of carbon emissions based on individual equity can be used as a theoretical tool for the allocating the international carbon emissions rights.

Disasters and disabled persons: An examination of the safety needs of a neglected minority

Disasters do not affect everyone in the same way. Safety needs of the ten per cnet of the population who are disabled prior to disaster must be ascertained; contingency plans and preparations should be made to ensure that disabled persons. Consideration of the safety needs of disabled persons in disasters seems to have beenlargely neglected by emergency services and those voluntary and statutory organizations directly concerned with disablement.     

基于价值取向的城市森林游憩服务需求研究

在调查南京城市森林游憩者的基础上,以森林价值取向为预测变量,对城市森林游憩服务需求进行了研究.研究表明,市民的森林价值取向包括生态取向、健康取向、文化取向、产品取向和消极取向五种类型;城市森林游憩服务需求则包括基本需求、拓展需求和个性需求三个层次.通过典型相关分析发现,对森林资源持“健康”、“文化”和“生态”价值取向的市民对森林游憩的“基本服务”需求明显,更重视森林的自然和文化环境保护;而持有“产品”和“消极”取向的市民,则希望森林游憩地能提供更多“拓展”和“个性”服务.在此基础上,提出了积极引导城市森林游憩者的政策建议.     

行人违规过街行为的激励理论模型

为减少行人违规过街现象,提高行人过街的安全性,从社会心理学角度研究行人违规过街行为的动因。基于内容型激励理论和过程型激励理论对行人违规过街的行为机理进行研究。首先,将行人过街需求按照不同的层次和类别划分为安全需要、省时省力需要、社会认同需要、尊重需要和自我实现需要。然后,基于期望理论,对行人违规过街行为激励水平、效价、期望值进行建模,得出行人违规过街的行为机理。最后,对模型结果的应用分析发现,通过降低违规过街需要的效价、增加交通规则制裁的期望和增加危险感知的期望能够减少行人的违规过街行为。     

DATA REQUIREMENTS OF A WATER QUALITY MANAGEMENT PROGRAM1

ABSTRACT: Routine data collection currently consumes a large amount of the total resources devoted to water quality management. All too often data collection becomes an end in itself, with little thought given to the purpose of the data collection. The problem generally stems from a lack of proper routine surveillance system design and a failure on the part of the designers to initially identify the data needs of the management program. This study attempts, in a general way, to delineate the data needs of a water quality management program. This first required an identification of the activities involved in water quality management. The activities were then discussed in terms of the types of information needed to successfully complete their assigned tasks. Several detailed examples are given. The results of the discussion are summarized and several strategies are proposed to relate the results to surveillance system design.     

FORECASTING INDUSTRIAL WATER REQUIREMENTS IN MANUFACTURING1

ABSTRACT Procedures used to establish current and prospective manufacturing water withdrawals in a river basin are described. The needs study incorporated a computerized analysis of industrial requirements at basin, county and county subarea levels. Current usage in the universe of industries was examined preparatory to the determination of probable future withdrawals, to facilitate plan formulation with constraints involving large masses of data. In preparing the needs estimates, it was assumed that employment data on an establishment basis would provide a reasonably current, consistent and continuing basis for relating the water demands of an industry to the operating rate of its establishments, when changes in employment were related to the trend in output per employee, and intake per employee was related to water use technology by analysis of reuse, and use by function. The forecasting technique described employs a well-defined data base, accounts for the major share of self-supplied needs generally disregarded in per-capita demand estimates, and differentiates between the “once-through” and recycled components of initial withdrawal.     

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.
