The Mersey Basin and its River Valley Initiatives: an appropriate model for the management of rivers?

Concepts of sustainable development have stimulated innovation in the delivery of environmental management. In particular, new partnership approaches have been developed in recognition of the need to adopt more holistic perspectives and facilitate multi-sectoral and cross-sectoral working. River catchments are complex systems and have been one particular focus of experimentation in environmental management mechanisms. This paper provides a brief overview of river management experience in the UK, charting changing approaches in terms of scope and organisation since the 1970s. This sets the context for a more detailed examination of the Mersey Basin Campaign and, in particular, its River Valley Initiatives. The paper concludes with an evaluation of the merits of this approach in relation to sustainable river management.     

Adverse Effects on Alfeios River Basin and an Integrated Management Framework Based on Sustainability

The Alfeios River, the longest and highest flow-rate river in Peloponnisos, constitutes an important water resource and ecosystem in Greece. In the present study, human activities in the Alfeios River Basin are described, and their impacts on water quality and the ecosystem are analyzed; effects resulting from interventions on river geomorphology between Flokas Dam and the river delta are determined. These actions have caused significant adverse impacts on the infrastructure (the dam, railroad, and road bridges), the level of aquifer water table and area water uses, and the aquatic and riparian ecosystem. A general integrated management strategy is formulated and a master management plan is proposed for resolving management problems in river basins. The plan considers local conditions and national requirements and complies with the European Communities legislation; it would help prevent further basin deterioration, improve water quality, and protect water resources and ecosystems in the area in accordance to sustainable development. The Alfeios River Basin serves as a case study in the development of the plan.Published online Note: This version was published online in June 2005 with the cover date of August 2004.

Environmental Information Management in Municipalities

This paper presents results from a study on the present needs for and management of environmental information in three Swedish municipalities. It was found that there are considerable differences between the municipalities studied, regarding needs for environmental information as well as approaches and tools used for providing the information needed—differences that seem closely related to the structures of the municipalities. The paper ends with a discussion on some general requirements for municipal environmental information management. Besides a need for analytical tools, it is argued that municipalities would have to pay more attention to political aspects of the environmental situation in environmental decision making, and thus in environmental information management.     

Who is a hydrocitizen? The use of dialogic arts methods as a research tool with water professionals in West Yorkshire,UK

ABSTRACT

There is currently a recognition of the need for more collaborative approaches to water management, which involve communities of place as proactive stewards of their local water environments. However, the desire for such participatory approaches sits awkwardly with the primarily technocratic orientation and practices of the responsible professional organisations in the water sector. Professionals sometimes struggle to communicate with, or respond to, communities stressed by flood and other impacts. This paper examines the concept of “hydrocitizenship” in relation to the engagement between professional stakeholders interested and involved in water landscape management, regulation and associated issues, and communities in the River Aire corridor, Yorkshire, UK. The case study-based research used innovative, arts-based exploratory approaches that aimed to examine participants’ relationships with water and how local environmental concerns about policy and water could be revealed. Group conversations and interviews were used as a strategy both to develop mutual understandings between participants and to inform the creation of public performances which stimulated further discussion and reflection. The paper focuses on reporting the role and experience of stakeholders, and identifies the emergence of unexpected synergies, where performance became the means of two-way communication between the different groups involved in the research. In particular, a flexible, creative and playful approach captured the imagination and gained interactions and creative collaborations within local communities and stakeholder groups. The paper concludes by reflecting on possible extensions of this work in other contexts.     

Municipal solid waste management in South Africa: from waste to energy recovery through waste-to-energy technologies in Johannesburg

ABSTRACT

“Waste-to-energy” (WTE) technologies have been presented as one of the avenues to improve the management of solid waste whilst promoting clean and healthy urban environments through the recovery of waste and generation of energy. Research suggests that with the right investment in technologies and institutional changes, waste can potentially become a resource that can contribute to the socio-economic development of cities. It is in this context that this paper presents a review of the literature on WTE technologies and their implications on sustainable waste management in urban areas. The paper particularly contributes to our understanding of WTE technologies and its potential on Municipal Solid Waste Management (MSWM) in Johannesburg, South Africa. It is estimated that the city of Johannesburg’s landfills airspace will be completely depleted by year 2023. This projection becomes a motivation for the identification of suitable WTE alternative avenues to manage waste in the city. The paper argues that WTE technologies can contribute significantly to sustainable waste management, economic growth, ecological and environmental well-being.     

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.     

Exploring the relationship between public environmental ethics and river flood policies in western Europe

Two styles of river flood management can be distinguished: dike reinforcement and the more sustainable 'Room for River' option. This paper investigates public adherences to these two management styles and whether their adherence correlates with their Visions of Nature. The focus is especially on people's image of the appropriate human/nature relationship, i.e. Mastery over nature, Stewardship of nature, Partnership of nature or Participation in nature. Other variables that are part of the analysis are the respondents' sense of place, safety perception and background variables. The results of a written survey among riverside residents in France, Germany and the Netherlands (N = 1811) show high adherences to the Room for River style and a rejection of dike reinforcement. A regression analysis shows that adherence to the Room for River style correlates with adherence to the image of Stewardship, while adherence to dike reinforcement is predicted by Mastery over nature. Thus, according to the public a policy shift from dike reinforcement to a more sustainable style is seen as a fundamental one, connected to a change in environmental ethics.     

Criteria for the Assessment of Sustainable Water Management

Pressure on the world’s water resources is increasing, restraining social and economic development in many countries, and threatening ecological values in others. In order to manage water resources in a more sustainable manner, new planning methodologies/processes for river basin management need to be developed. This study attempts to construct a set of useable normative criteria for the analysis and evaluation of such processes. The criteria were designed as a response to the lack of deductive approaches in the evaluation of methodologies and working procedures used in the context of river basin management, making it possible to highlight their potential for sustainable development. The criteria are based on the twin concepts of participation and integration. These concepts function as well-established dimensions of both sustainable development and sustainable river basin management, and they are of significant methodological relevance. A synthesis of the key aspects connected to the two concepts is undertaken, based on a broad literature review. Focus is laid on how in methodological terms, and in relation to regional water management, to achieve participation and integration in a decision-making or planning process. The criteria are concerned with how knowledge and values are integrated into the planning process and how commitment, legitimacy, or acceptance for the resulting plan is generated.     

Managing Indirect Environmental Impact within Local Authorities' Standardized Environmental Management Systems

Abstract

Many local authorities use standardized environmental management systems (EMSs) to improve their environmental management. These authorities often find it difficult to manage environmental impact caused by their exercise of authority i.e. indirect environmental impact (IEI) within their EMSs. Since this is connected to their core activities, it is important to understand how IEI could be more efficiently managed with respect to EMS work. The purpose for this paper is to study if and how IEI could be managed within the framework of EMS. In this study we have identified two different approaches to managing IEI. Because managing IEI is complex, it is often ignored when initiating EMSs or managed by explicitly avoid mentioning the concept. Managing IEI is seen as a matter of maturity within the organization. The paper concludes with a discussion regarding a developed definition of IEI and how management of IEI could be facilitated.     

Environmental Management Systems and Co-operation in Municipalities

Due to the complex character of environmental issues there has been a call for change towards integration and co-operation on the development and environmental management scene. This holds true at all levels of society, from the global to the local. Due to cultural differences between different professions in municipalities, it may be hard to reach co-operation between different actors in municipal environmental management (MEM). Based on the present situation in Sweden in general and the municipality of Västera § s in particular, this paper discusses how co-operation in MEM may be promoted by the adoption of an environmental management system (EMS) in an entire municipality. Results from the study suggest that municipality-wide implementation of EMSs may help to bridge professional culture and language gaps. An EMS may provide the basis of a formal network that functions as a common platform and structure for environment-related discussion and work in different municipal authorities and companies, and thereby facilitate communication and co-operation among the actors in MEM.     

Stakeholders' views towards flood risk management in the Paz River catchment area of Guatemala and El Salvador

The river Paz is a transboundary river that flows through Guatemala and El Salvador. Its frequent floods endanger the lives and livelihoods of downstream communities. Attempts have previously been made to develop flood management programmes for this watershed. However, these approaches were generally made by high-level governmental institutions with few if any contributions from floodplain communities and other stakeholders. Recognising that public consultation is a key aspect in flood management programmes, we intend in this work to extract different stakeholders' views regarding current and future flooding and flood management programmes in the Paz River basin. This is achieved using Future Scenarios Workshops with a projected time horizon of 30 years. The exercise was expected to identify consensual short- and medium–long-term flood management strategies for the Paz River basin that draws on input from inhabitants of flood-prone areas and other stakeholders.     

Integrated economic-ecological analysis and evaluation of management strategies on nutrient abatement in the Rhine basin

Management of river basins involves the making of informed choices about the desired levels of economic activities and ecosystem functioning in the catchment. Information on the economic and ecological effects of measures as well as their spatial distribution is therefore needed. This paper proposes the following instruments to support decision-making in river basins: (1) the linking of models and indicators to describe the economic and ecological effects of management actions and their spatial distribution and (2) an extended evaluation framework that aims to evaluate management actions on three objectives for sustainable river management. These are cost-effectiveness, spatial equity, and environmental quality. This paper illustrates the potential of these instruments for river basin management by a case-study on nutrient management in the Rhine basin. In this case-study four nutrient abatement strategies are formulated, based on policies of the International Commission for the Protection of the Rhine and the North Sea Commission. These strategies are analysed and evaluated on their contribution to the three management objectives. Results show that none of these strategies score highest on cost-effectiveness, spatial equity and environmental quality simultaneously. It appears that cost-effectiveness is in conflict with environmental quality, whereas spatial equity and cost-effectiveness show quite close correspondence. This means that a trade-off has to be made between costs and spatial equity on the one hand, and environmental standards on the other hand. This paper offers a framework to make these trade-offs more explicit and provides quantitative information on cause-effect relationships, economic and environmental effects and the spatial distribution of these effects for various management strategies. This information can be particularly useful in the development of compromises required to establish international agreement and co-operation.

Freedom Space for Rivers: A Sustainable Management Approach to Enhance River Resilience

River systems are increasingly under stress and pressure from agriculture and urbanization in riparian zones, resulting in frequent engineering interventions such as bank stabilization or flood protection. This study provides guidelines for a more sustainable approach to river management based on hydrogeomorphology concepts applied to three contrasted rivers in Quebec (Canada). Mobility and flooding spaces are determined for the three rivers, and three levels of “freedom space” are subsequently defined based on the combination of the two spaces. The first level of freedom space includes very frequently flooded and highly mobile zones over the next 50 years, as well as riparian wetlands. It provides the minimum space for both fluvial and ecological functionality of the river system. On average for the three studied sites, this minimum space was approximately 1.7 times the channel width, but this minimum space corresponds to a highly variable width which must be determined from a thorough hydrogeomorphic assessment and cannot be predicted using a representative average. The second level includes space for floods of larger magnitude and provides for meanders to migrate freely over a longer time period. The last level of freedom space represents exceptional flood zones. We propose the freedom space concept to be implemented in current river management legislation because it promotes a sustainable way to manage river systems, and it increases their resilience to climate and land use changes in comparison with traditional river management approaches which are based on frequent and spatially restricted interventions.     

Effect of Human Activities on Overall Trend of Sedimentation in the Lower Yellow River,China

The Yellow River has been intensively affected by human activities, particularly in the past 50 years, including soil–water conservation in the upper and middle drainage basin, flood protection in the lower reaches, and flow regulation and water diversion in the whole drainage basin. All these changes may impact sedimentation process of the lower Yellow River in different ways. Assessing these impacts comprehensively is important for more effective environmental management of the drainage basin. Based on the data of annual river flow, sediment load, and channel sedimentation in the lower Yellow River between 1950 and 1997, the purpose of this paper is to analyze the overall trend of channel sedimentation rate at a time scale of 50 years, and its formative cause. It was found in this study that erosion control measures and water diversion have counteractive impacts on sedimentation rate in the lower Yellow River. Although both annual river flow and sediment decreased, there was no change in channel sedimentation rate. A regression analysis indicated that the sedimentation in the lower Yellow River decreased with the sediment input to the lower Yellow River but increased with the river flow input. In the past 30–40 years, the basin-wide practice of erosion and sediment control measures resulted in a decline in sediment supply to the Yellow River; at the same time, the human development of water resources that required river flow regulation and water diversion caused great reduction in river flow. The former may reduce the sedimentation in the lower Yellow River, but the reduction of river flow increased the sedimentation. When their effects counterbalanced each other, the overall trend of channel sedimentation in the lower Yellow River remained unchanged. This fact may help us to better understand the positive and negative effects of human activities in the Yellow River basin and to pay more attention to the negative effect of the development of water resources. The results of this study demonstrate that, if the overuse of river water cannot be controlled, the reduction of channel sedimentation in the lower Yellow River cannot be realized through the practice of erosion and sediment control measures.     

Local Environmental Investments and Sustainable Development: The evaluation of environmental projects in Scotland supported by the European Agriculture Guidance and Guarantee Fund

In the UK for the period 1994-99, a broad range of environmental projects were given financial support through the European Agriculture Guidance and Guarantee Fund under the Objective 1 and Objective 5b programmes. This paper is concerned with the ex-post evaluation of these projects set within a Sustainable Development framework. The aim was to identify project types or characteristics that offered the greatest return on investment. A classification of six broad project types was adopted. The evaluation revealed that there were significant differences between individual projects with respect to the type and scale, and temporal and social distribution of the benefits they delivered. In particular, as well as delivering environmental and economic benefits, many projects made a significant contribution to the development of human and social capital. The paper concludes that it is possible to improve the basis for future project selection in order to maximise the returns on environmental investments in the context of sustainable development.     

Expanding the benefits of environmental management systems through DFE

Industry's role in environmental protection is changing and growing. Increasing evidence shows that a corporation's understanding and response to environmental issues and concerns can have strategically important consequences for some kinds of businesses.¹ Focusing on concepts of prevention, industry has developed and struggled with a number of environmental approaches, all of which attempt to link the environment with common business practice. Industry has followed and in some cases embraced concepts and approaches like sustainable development, eco-efficiency, green manufacturing, pollution prevention, and extended product responsibility. A particularly timely and promising strategy to reduce the environmental impact of both manufacturing and product use while enhancing business success is the integration of environmental management systems (EMS) with design for the environment (DFE) efforts. A desirable relationship can and should exist between DFE and EMS. This relationship has not been well understood, but is crucial to fulfill the promise of each. In application, the institutionalization of DFE in an organization is difficult and tenuous at best. Some authors suggest that management issues block the implementation of DFE.² Others say that DFE has not been institutionalized to the extent that pollution prevention has.³ This article suggests that through an explicit connection between an EMS and DFE, DFE can extend the promise of EMS to reduce industry's environmental impact and produce business success, and it can do so in an ongoing way. The authors will show the importance of an EMS/DFE linkage, suggest company types that might benefit from investigating these approaches, and then review a series of DFE tool types.     

Marine protected areas and local coastal conservation and management in Hong Kong

Abstract

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.
