The Importance of Process in Ecosystem Management: Lessons from the Lachlan Catchment,New South Wales,Australia

Effective river management requires integration of biophysical and human dimensions of the ecosystem, which in turn involves the development of new forms of decision-making processes and institutional frameworks. In New South Wales, institutional changes to river management have been formalized in the Water Management Act 2000. This paper presents the findings of a case study that investigated decision-making processes in the establishment of environmental flow regimes for the Lachlan River in western New South Wales. The study was based on document analysis, observation and interviews with members and support staff of a stakeholder-based river management committee. The findings of the study highlight social capital, adaptive management and consensus decision making as key components in establishing environmental flow regimes as part of a participatory approach to river management.     

Off-site movement of endosulfan from irrigated cotton in New South Wales

The fate and transport of endosulfan (6,7,8,9,10,10-hexachloro-1,5, 5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepin 3-oxide) applied to cotton (Gossypium hirsutum L.) fields were studied throughout three consecutive years on two selected locations in New South Wales (Australia). Rates of dissipation from foliage and soil, volatilization from the field, and transport of residues in irrigation and/or storm runoff waters were measured in order to estimate a total field balance. Dissipation of endosulfan from both foliage and soil is best explained by a two-phase process rather than by a first-order decay. Half-lives of total endosulfan toxic residues (alpha- and beta-endosulfan and the sulfate product) in the first phase were 1.6 d in foliage and 7.1 d in soil, and could be explained by the rapid volatilization of the parent isomers in the first 5 d (up to 70% of endosulfan volatilizes). In the second phase, half-lives were 9.5 d in foliage and 82 d in soil, mostly due to the persistence of the sulfate product. Concentration of endosulfan residues in runoff water varied from 45 to 2.5 microg L(-1) depending on the residue levels present on field soil at the time of the irrigation or storm events. These in turn are related to the total amounts applied, the cotton canopy cover at application, and the time since last spraying. Most of the endosulfan in runoff was found in the water phase (80%), suggesting it was bound to colloidal matter. Total endosulfan residues in runoff for a whole season accounted for no more than 2% of the pesticide applied on-field.     

Policy And Practice Environmental Assessmentand Planning: A Chronology of Development in England and Wales

The development of regulations to implement Environmental Impact Assessment (EIA) in England and Wales occurred initially as a response to European Community Directive obligations. Since then, a proliferation of regulations has resulted from the need to meet those obligations which were not covered successfully by the first tranche of legislation; the desire to extend the range of project types requiring EIA beyond those specified in the Directive; and the need to respond to changes brought about by privatization.As a result, current regulations relating to EIA are extremely complex and are in a constant state of flux. This inevitably causes problems for those responsible for their implementation. Ten years after the 1985 Environmental Impact Assessment Directive was notified to the Member States, it has undergone a review and the European Commissionhas reached a common position on the proposedamendments.The implementation date for Member States to meet the requirements of the amended Directive is 31 December 1997 (ENDS, 1996). However, the 1985 Directive has yet to be fully implemented in the UK.     

Profenofos residues in wild fish from cotton-growing areas of New South Wales, Australia

The organophosphorus (OP) pesticide profenofos (O-4-bromo-2-chlorophenyl O-ethyl S-propyl phosphorothioate) is used heavily in cotton-growing areas of eastern Australia toward the end of the growing season. European carp (Cyprinus carpio), bony bream (Nematalosa erebi), and mosquitofish (Gambusia holbrooki) were collected from the cotton-growing areas around Wee Waa, New South Wales, to determine the relationship between profenofos residues and acetyl-cholinesterase (AChE) activity in wild fish. Profenofos concentrations in water, sediment, and fish tissue reflected its general level of use; levels in March 1994 were significantly higher than in 1993 and generally decreased in May, 6 wk after cessation of spraying. Residues in carp and bony bream generally correlated with concentrations in water and sediment, although residues in fish tend to persist longer at some sites. Acetylcholinesterase inhibition was a useful indicator of profenofos exposure within a season, particularly if linked with residue measurements. Bony bream and gravid female mosquitofish recovered AChE levels more slowly than carp or nongravid mosquitofish. Recovery in creeks was generally more rapid than in lagoons.     

Problems and Prospects in Local Environmental Assessment: Lessons from the United States

Local environmental assessment (EA), mandated by five US states, has introduced complex management issues for practitioners and policy makers. Based on a review of statutes, case law, and prior EA evaluations,this paper outlines three key issue areas for local EA: linking comprehensive planning and EA; making the threshold determination process more certain; and balancing mitigation with public participation. The paper argues that all the issues reflect a central tension in environmentalassessment between procedural consistency and the need for contingent responses to conditions that differ among the projects to be reviewed.     

Survey of land degradation in New South Wales,Australia

A survey of land degradation was undertaken in New South Wales, Australia during 1987–1988. The aims of the survey were to assess the location, extent, and severity of ten forms of degradation and to present the data in map and statistical form. Sample points were located on a regular grid. The method was designed so that data could be acquired from aerial photographs, expert local knowledge, and limited field checking. Individual statewide maps were prepared for each form of degradation. Map data were shown in pixel form. Sheet and rill erosion and soil structure decline were confined mostly to lands used for cropping. Gully erosion was commonly found across the state, while mass movement was confined to steeper lands. There were three severe areas of dryland salinity; irrigation salinity was mapped in parts of the southern irrigation lands. Induced soil acidity was severe in some cropping and pasture lands. Absence of tree regrowth was a noticeable feature of lands used for cropping. The survey enabled community awareness of the problems of land degradation to be increased, in addition to assisting regional land managers in resource allocation. The survey also provided the basis for the future location of sites that could be used to monitor the trends in the status of land degradation.     

Riverbanks and the law: The arbitrary nature of river boundaries in New South Wales,Australia

Key aspects of environmental management exist within a legislative framework. The Rivers and Foreshores Improvement Act 1948 (NSW) and several Regional Environmental Plans created under the Environmental Planning and Assessment Act 1979 (NSW) make reference to ‘the top of the bank’ for defining areas of protected land adjacent to rivers, within which development consent may be required. It is an arbitrary term and its use within the Rivers and Foreshores Improvement Act 1948 (NSW) leads to confusion. This paper examines the range of definitions of ‘the top of the bank’ in respect of natural watercourses and aims to provide a more lucid and effective definition that will clarify existing ambiguities in legal interpretation. The paper examines the historical origins of the phrase ‘top of the bank’, finding that stereotyped Eurocentric views of what a river ‘should look like’ have impaired the legal definition for Australian rivers, thereby influencing common law and the development of statutory definitions. Judicial applications of the phrase ‘top of the bank’ are examined from a geomorphological perspective, demonstrating the misconceptions of the term in a legal context. The paper identifies the existence of widespread support for the need to protect land adjacent to rivers in the interests of environmental, economic and social sustainability. It concludes by calling for legislative reform that is both tailored to the individual site and consistent with overarching goals at the catchment scale.     

From wasteland to wetland: creating a community ecological resource from waste water in regional New South Wales

In areas where rivers have been altered and regulated through dams, the effect on wetland ecosystems can lead to 'wastage' of the land as natural systems are destroyed. In response to the effects of streamflow regulation on a wetland near the city of Albury, on the Murray River, the development of the Wonga Wetlands and associated site rehabilitation addresses two key issues: wasteland and waste water. A Community Advisory Committee has been actively and directly involved in the project, initiated and implemented by the Albury City Council, to restore an area of original wetland into a community ecological resource that utilises 100% of the domestic, commercial and industrial urban 'waste' water from the city's water treatment plant. This project represents a significant direction in the way communities and local governments approach resource recovery. This paper analyses the Wonga Wetlands project from the perspective of sustainable management of waste in terms of water resources and presents it as a model for community-based environmental application and long-term resource sustainability.     

Environmental investment recovery practices and opportunities: Lessons from project RENEWAL

In the Autumn 1994 issue of Total Quality Environmental Management you learned about Project RENEWAL, a cooperative business project to investigate and promote the linkages between ecology, technology, and business economics. Project RENEWAL stands for Resource Efficiency Network to Eliminate Waste and Liability. This collaborative effort focused on equipment and inventory assets, exploring how better capital asset management can benefit profitability and improve environmental protection. Participants in the project included representatives from industry, consulting, local and state government, environmental agencies, trade groups, and academia. This article describes three specific activities conducted by the RENEWAL participants and suggests ways to improve the success of future projects looking to improve the investment recovery of “impaired” capital assets.

Environmental Protection in the Russian Federation: Lessons and Opportunities

Environmental managers in Russia face severe problems, both from Soviet-era and continuing environmental degradation and due to the weakness of current institutions with responsibilities for environmental protection. This paper draws on surveys, a case study of water pollution and workshops on Russian environmental decision making to explore prospects for environmental improvements. Using concepts from the regulatory reform literature, it focuses on the use of market incentives, the construction of a civil society and community involvement, and emphasizes that Russian non-governmental organizations may have a particularly important role to play in improving environmental management. Solidifying their legal base, coalition-building skills and the capability to conduct independent, pragmatic policy analyses would enhance their contribution.     

Environmental Compensation and the Mediation of Environmental Change: Making Capital out of Cardiff Bay

The scope for compensating for environmental loss or degradation with some form of balancing environmental gain (such as habitat creation) has attracted critical attention from conservationists and policy makers. However, it is increasingly apparent that concentrating on technical skills, and adopting a linear analytical framework, disguise the range of social processes at work. Engaging in environmental compensation is, almost inevitably, a process of considerable ecological, evaluative and institutional transformation. Moreover, taking increasing control of this process through detailed management may accelerate the transformation of nature into 'capital'. These arguments are developed through a case-study of Cardiff Bay, where the implementation of habitat creation compensating for the loss of inter-tidal mud flats became linked to the implementation of the European Habitats Directive, a policy lever which served to both intensify and rationalize these transformations.     

Estimating the opportunity costs of biodiversity protection in the Brigalow Belt, New South Wales

The New South Wales Government recently introduced the Native Vegetation Conservation Act to protect the native grassland and woodland of the state. The Act protects biodiversity by preventing farmers from clearing such vegetation on their properties but, as a consequence, reduces farm incomes and land values. An economic model of the relationship between land value and percentage of farm in native vegetation is integrated with an ecological model of the relationship between species lost and percentage of the farms in native vegetation. The integrated framework is applied to estimate the opportunity costs of the Act for one important agricultural area of the state, the northern part of the Brigalow Belt South Bio-Region. If all the vegetation were protected, the reduction in land value would be at least 14.3%, which is an opportunity cost of at least 148.5 dollars m for the area. Both the benefits and costs of biodiversity protection must be accounted for, so risk simulations are then combined with benefit-cost analysis to compare the benefits of biodiversity protection to these costs.     

Deafness and Disability—Forgotten Components of Environmental Justice: Illustrated by the Case of Local Agenda 21 in South Wales

This paper contributes to discussions of procedural aspects of environmental justice, understood as having procedural and substantive dimensions. It argues that the struggle for environmental justice must recognize the oppression of disabled people as part of the essential broadening of the notion of citizenship, which continues to be the focus for struggle for the international disability movement. Its case study of an area of South Wales suggests that at present disabled people, and the struggles of the disability movement, do not really feature in the way environmental activists (inside and outside government) see the world. This huge omission must be addressed, but in a way that avoids interpreting disability as an administrative category, and must engage with disablement as a political and contested notion. The paper develops the significance of this contention by considering the case of Deafness, which is entirely different from hearing impairment. The paper's case study, presented as an illustration of its arguments, shows that to regard Deaf people in South Wales as part of some generic category of 'disabled people' would be to ignore their self-identification as a distinctive linguistic community. Moreover, there is some evidence that Deaf people have a distinctive view of, and set of concerns about, quality of life, reflecting their distinctive experience of social injustice and marginalization. This underlines the necessity for a serious engagement with disablement as a political category, and the disability movement as a struggle for social justice, within the promotion of environmental justice.     

Land Use Planning and Environmental Capacity: Reassessing the Use of Regulatory Policy Tools to Achieve Sustainable Development

Just as it is now widely accepted that the planning system has a role to play in achieving sustainable development, so the concept of environmental capacity has achieved increasing prominence as a means of realizing that role. This paper considers the debate on the concept of environmental capacity, reviewing both the mainstream model and Jacobs' more nuanced social constructionist model. In doing so, it raises concerns about the appropriateness of regulatory policy tools and the implications for the distribution of environmental and other impacts. The discussion highlights the potential for using the planning system to promote change rather than resist it. In doing so, it suggests the need to consider a wider range of policy tools to achieve change at the local level and to clarify the dimensions of sustainable development that local planning can contribute to.     

Flooding and the Role of Planning in England and Wales: A Critical Review

In this paper the authors raise some important questions about the extent to which planning is fostering an environment susceptible to flooding. They argue that severe UK flooding incidents in recent years should result in the government re-examining the planning system to ensure relevancy and effectiveness in dealing with such problems in the future. They identify where the current policy and practice weaknesses lie in planning to limit both flood source and flood impact areas and suggest ways in which the government and the profession could take remedial steps to increase local and regional sustainability.     

Threatened Species Conservation in New South Wales,Australia: A Review of the Value of the Eight-part Test

The Threatened Species Conservation (TSC) Act, introduced in 1995, represents a significant attempt to conserve and restore biodiversity within the state of New South Wales, Australia. This Act aims to integrate land use planning and environmental impact assessment legislation by placing increased responsibility on applicants, proponents, consent and determining authorities, and the New South Wales National Parks and Wildlife Service, in the fields of environmental planning, development control and biodiversity conservation. The TSC Act introduced a set of eight factors which have to be considered by decision makers in determining whether a development is likely to have a significant effect upon threatened species, populations, ecological communities or their habitats (the threatened biota) as listed in the Act. These eight factors are commonly referred to as the 'eight-part test'. Fifty environmental impact statements (EISs) containing eight-part tests for development proposals were obtained. The adequacy of scoping and survey exercises, the number of species identified and afforded the eight-part test, and the actual responses to each of the eight factors contained within the test, using a series of criteria, were ascertained. Sixty per cent provided an adequate scoping exercise; 6% of the surveys for flora species, and none for fauna species carried out, were adequate in terms of identifying all threatened species on the development site. Seven hundred and thirty-seven species listed in the Act were identified, 36% of which were omitted from the eight-part test procedure. The eight sections of the eight-part test were completed to a varying degree of adequacy, with none of the EISs completing all eight sections satisfactorily. Both section 4 (regarding the impacts of a development in terms of habitat isolation) and section 8 (regarding the distribution of species potentially affected by a development) were inadequately completed in all 50 EISs.
