The climate's long-term impact on New Zealand infrastructure (CLINZI) project - a case study of Hamilton City, New Zealand

Infrastructure systems and services (ISS) are vulnerable to changes in climate. This paper reports on a study of the impact of gradual climate changes on ISS in Hamilton City, New Zealand. This study is also the first of its kind to be applied to New Zealand ISS. In the future, the CLINZI project will extend to other areas of New Zealand. Using historical climate data and four climate change scenarios, we modelled the impact of climate change on aspects of water supply and quality, transport, energy demand, public health and air quality. Our analysis reveals that many of Hamilton City's infrastructure systems demonstrated greater responsiveness to population changes than to gradual climate change.

Processes in Pollution Management: An Australian Model

/ This paper describes a model of the social and institutional processes involved in the solution of major pollution problems from the time they are first identified until they are resolved. The model is empirically demonstrated using four case studies of water and air pollution problems from Sydney, New South Wales, Australia. Each process of the model is quantified by the use of an indicator, e.g., number of articles in newspapers to measure the process "publicconcern," number of pages of text devoted to parliamentary debates to measure the process "political action." The case study data are presented on a time-line graph that shows the duration and magnitude of each process. The paper illustrates three aspects of the solution of major pollution problems: the long time frames involved, the importance of public opinion in initiating the solution process, and the partial nature of solutions-problems may be politically resolved but often a complete solution is not achieved. An understanding of social and institutional processes and time frames will enable planners and policy makers to communicate to the public and politicians the consequences of delay in acting to solve pollution and to direct attention to critical areas to expedite solutions.KEY WORDS: Pollution problems; Management process model; Performance indicators; Air pollution; Water pollution     

我国城市大气污染现状与特点

中国城市化和工业化的快速发展与能源消耗的迅速增加，给中国城市带来了很多空气污染问题。20世纪70年代期间，煤烟型污染排放成为中国工业城市的特点；80年代，许多南方城市遭受严重的酸雨危害；近年来，汽车尾气排放的NOx、CO及随后形成的光化学烟雾，使得许多大城市的空气质量恶化。城市空气污染影响着城市居民的健康和城市的发展。为控制空气污染和保护大气环境质量，我国政府已经实施了许多规划。本文概述了当前中国城市特别是重点城市的空气质量状况，描述一些主要城市空气污染物包括总悬浮颗粒、PM10、PM2．5、SO2、酸雨、NOx/NO2的特点。尽管采取了很多应对措施，但目前我国城市的空气质量依然不容乐观，文中还讨论了未来城市空气污染控制面临的问题。     

Comparative Analysis of New Zealand and US Approaches for Agricultural Nonpoint Source Pollution Management

The role of the central government in New Zealand is generally limited to research and policy development, and regional councils are responsible for most monitoring and management of the problem. The role of the federal government in the United States includes research and monitoring, policy development, and regulation. States also have a significant management role. Both countries rely on voluntary approaches for NPS pollution management. Very few national water quality standards exist in New Zealand, whereas standards are widely used in the United States. Loading estimates and modeling are often used in the United States, but not in New Zealand. A wide range of best management practices (BMPs) are used in the United States, including buffer strips and constructed/engineered wetlands. Buffer strips and riparian management have been emphasized and used widely in New Zealand. Many approaches are common to both countries, but management of the problem has only been partly successful. The primary barriers are the inadequacy of the voluntary approach and the lack of scientific tools that are useful to decision-makers. More work needs to be performed on the evaluation of approaches developed in both countries that could be applied in the other countries. In addition, more cooperation and information/technology transfer between the two countries should be encouraged in the future.     

Evaluating policy options for managing diffuse source water quality in Lake Taupo,New Zealand

Environmental policy makers are interested in ways to prevent environmental degradation without significantly limiting economic and social development. Increasingly, market-based instruments are being incorporated into the suite of policy tools to accomplish these aims. However, the lack of information on market-based instruments accessible to non-economists limits understanding of how and when a market-based instrument can be integrated into a traditional policy regime. This paper aims to address the lack of accessible information using a generic screening process for policy instruments demonstrated through application to a non-point source pollution problem in Lake Taupo, New Zealand.     

Application of the pressure-state-response framework to perceptions reporting of the state of the New Zealand environment

The Pressure-State-Response framework for environmental reporting was used as a basis to develop a long-term study of people's perceptions of the state of the New Zealand environment. A postal survey of 2000 people, randomly drawn from the New Zealand electoral roll was used to gather data--an effective response rate of 48% was achieved. A range of different resource sectors was examined. We report on New Zealand's air, native animals and plants, and marine fisheries, as well as New Zealand compared to other developed countries. Respondents generally considered that in terms of pressures, states and responses, New Zealand was performing better than other developed countries and that for the resources examined here overall performance was in the adequate to good range, except for marine fisheries. The survey appears to be a useful tool for linking perceptions data into State of the Environment reporting. It also helps identify policy issues where perceptions do not match other scientific evidence or management initiatives. Such findings can be important for the successful implementation of policy measures.     

Risk assessment for atmospheric environmental management: a case study in the Hunter Region of New South Wales,Australia

The theoretical framework of a risk assessment scheme is applied to air quality assessment in a developing region in Australia, the Hunter Valley in the state of New South Wales. It is found that the application of such a scheme high-lights a number of inadequacies in the air quality management. New modeling methodologies are found to be necessary to assess some air quality impacts, as existing knowledge is inadequate. The importance of extensive data bases is underlined as is the need for social surveys to supplement air pollution monitoring when gauging aesthetic effects of air pollutants.A visiting fellow on leave from the School of Australian Environmental Studies, Griffith University, Brisbane, Queensland, Australia.     

From concept to practice: Implementing cumulative impact assessment in New Zealand

In 1991, provisions for environmental impact assessment in New Zealand were changed significantly with the enactment of the Resource Management Act. Among other provisions, this act requires consideration of cumulative impacts in environmental assessment activities undertaken by planners in newly created regional authorities and district and city councils. The institutional context in which the act is being implemented offers both opportunities and constraints to cumulative impact assessment. A lack of methods for CIA is a recognized problem. However, methods that have been developed for environmental impact assessments can be modified to incorporate second-, third-, and fourth-order impacts as well as to identify the direction and magnitude of additive and synergistic impacts. Layered matrices and combined networks are examples of such methods. While they do not allow for scientific prediction, they do provide the practitioner with the ability to consider the cumulative impacts of decisions. This is crucial in New Zealand, where statutory requirements are ahead of established methodologies.

Towards sustainable management of natural ecosystems on farms? a New Zealand perspective

Many New Zealand farms still have large remnant indigenous forest patches. This paper discusses constraints and opportunities for the sustainable management of these remnants. First, the paper analyses why the specific ecological situation of the New Zealand vegetation poses severe constraints for sustainable management. Second, results from a case study are presented suggesting that analysis of farmers’ attitudes to remnant ecosystems might provide valuable data for improving existing environmental legislation. Finally, the possible management implications of the new Resource Management Act 1991 and Forest Amendment Act 1993 are discussed. It is argued that these Acts may bring to an end a thousand years of wilful and accidental destruction of New Zealand's natural environment.

Access rights for outdoor recreation in New Zealand: some lessons for open country in England and Wales

Access opportunities for outdoor recreation in New Zealand and England and Wales are classified according to their conformity with collective, citizenship or exclusion rights and their degrees of permanence. Alternative criteria for the apportionment of access rights are considered in the context of this classification. Different criteria for rights apportionment are found to be appropriate according to different circumstances in the context of pluralist provision. Policy developments in New Zealand are compared with those in England. After 150 years of a dominance of collective rights in New Zealand current policy is shifting provision towards exclusionary rights. In England, there is a policy shift in the other direction, towards collective rights. Lessons for the development of collective rights in England are drawn from the New Zealand experience in relation to styles of governance, public preferences, public cost, insurance liability and the potential of markets.     

Partnerships for sustainability: Effective practice?

This paper presents as case studies some New Zealand local government sustainable development initiatives in cleaner production and civic building design. From a series of structured interviews with key players, it describes key motivators and demotivators and puts these in the context of behaviour change theory. These enable a set of actions for local government to be developed that, if applied, could result in an advancement of the sustainable development agenda. However, other critical factors are given that are external to these actions and on which their overall success is dependent. In reviewing these factors as a group we conclude that far greater understanding of the partnership formation process and its dynamic in engendering successful sustainable development decision-making processes is crucial to move beyond the rhetoric of partnerships and enter the more complex and difficult world of truly participatory approaches.     

Skewed Riskscapes and Environmental Injustice: A Case Study of Metropolitan St. Louis

This article presents a case study of Toxics Release Inventory (TRI) air pollution exposure risks across metropolitan St. Louis. The first section critically reviews environmental justice research and related barriers to environmental risk management. Second, the paper offers a conventional analysis of the spatial patterns of TRI facilities and their surrounding census block group demographics for metropolitan St. Louis. Third, the article describes the use of an exposure risk characterization for 319 manufacturers and their air releases of more than 126 toxic pollutants. This information could lead to more practical resolutions of urban environmental injustices. The analysis of TRIs across metropolitan St. Louis shows that minority and low-income residents were disproportionately closer to industrial pollution sources at nonrandom significance levels. Spatial concentrations of minority residents averaged nearly 40% within one kilometer of St. Louis TRI sites compared to 25% elsewhere. However, one-fifth of the region's air pollution exposure risk over a decade was spatially concentrated among only six facilities on the southwestern border of East St. Louis. This disproportionate concentration of some of the greatest pollution risk would never be considered in most conventional environmental justice analyses. Not all pollution exposure risk is average, and the worst risks deserve more attention from environmental managers assessing and mitigating environmental injustices.     

Operational Atmospheric Modeling System CARIS for Effective Emergency Response Associated with Hazardous Chemical Releases in Korea

The Chemical Accidents Response Information System (CARIS) was developed at the Center for Chemical Safety Management in South Korea in order to track and predict the dispersion of hazardous chemicals in the case of an accident or terrorist attack involving chemical companies. The main objective of CARIS is to facilitate an efficient emergency response to hazardous chemical accidents by rapidly providing key information in the decision-making process. In particular, the atmospheric modeling system implemented in CARIS, which is composed of a real-time numerical weather forecasting model and an air pollution dispersion model, can be used as a tool to forecast concentrations and to provide a wide range of assessments associated with various hazardous chemicals in real time.This article introduces the components of CARIS and describes its operational modeling system. Some examples of the operational modeling system and its use for emergency preparedness are presented and discussed. Finally, this article evaluates the current numerical weather prediction model for Korea.Published online     

Road Traffic Pollution Monitoring and Modelling Tools and the UK National Air Quality Strategy

This paper provides an assessment of the tools required to fulfil the air quality management role now expected of local authorities within the UK. The use of a range of pollution monitoring tools in assessing air quality is discussed and illustrated with evidence from a number of previous studies of urban background and roadside pollution monitoring in Leicester. A number of approaches to pollution modelling currently available for deployment are examined. Subsequently, the modelling and monitoring tools are assessed against the requirements of local authorities establishing air quality management areas. Whilst the paper examines UK-based policy, the study is of wider international interest.     

New Zealand's Planning Revolution Five Years On: A Preliminary Assessment

It is now five years since New Zealand radically changed its environmental planning regime by introducing the Resource ManagementAct 1991 (RMA). The RMA swept away the entire tradition of town and country planning which New Zealand had inherited from Britain, replacing this with an integrated framework for resource management that attempts to emphasize efficiency, sustainability and public participation in the new system of development control. These new emphases of the RMA reflect the agendasof New Zealand'sgreen and New Right lobbies which gained political influence during the 1980s.However,the green and neo-liberal agendaswhich the RMA attempts to embrace are potentially contradictory. In this paper we investigate this potential contradiction through a preliminary assessment of the first five year's of the new legislation's implementation.In particular, we focus on the operational success, or otherwise, of three 'efficiency' innovations of the RMA, and consider the consequences of these for the environmental and public participation ideals of the legislation.
