Using Collaborative Technology in Environmental Strategy Development

This viewpoint explores, through a case study in Malawi, the application of collaborative technology tools to support National Environmental Strategy Development initiatives with the public and private sectors in Africa. A particular type of groupware, Group Support Systems, is introduced as a technology and approach that enables large groups of stakeholders to be involved in efficient and effective decision making. It helped the different ministries, community leaders, the private sector, NGOs, and different donors to find new and challenging opportunities for collaboration. The results of the case study show how an environmental strategy, including a prioritised plan of action, was developed and presented to the Ministry within three days. The most important lessons are identified. Participants to the presentation of the paper will be given hands-on experience using these tools.     

Private–public partnership: An exceptional solution in nature conservation in Norway

Abstract

In Norway, traditional nature conservation by government declaration is still the dominant way of protecting nature areas of national and international interest. This article presents some results from a case study of one exceptional case of private–public partnership in nature conservation. Strong opposition among local actors resulted in conservation by legal contracts between public and private actors. Discussing some possible explanations, the authors argue that a rather special network among the local community and central government and a rather creative combination of environmental and agricultural policy instruments were essential for this particular outcome.     

Positive Planning for Wind-Turbines in an Urban Context

Abstract

An international concern with climate change has prompted a political commitment to the use of renewable energies. Yet, the operationalization and management of this political objective may be frustrated at the local level, where, it is suggested, an implementation impasse exists. This paper reports on a case study that examines the planning issues around the harvesting of wind at an urban brownfield site in Scotland. The paper discusses the nature of the state–market–civil relations involved in the development management of private wind-energy infrastructure, and the potential for a positive mediating role for the planning system.     

The production of uneven access to land and water in peri-urban spaces: de facto privatisation in greater Accra

ABSTRACT

Peri-urban spaces are frontiers of privatisation where inequalities in access to land and water evolve. In this article, we analyse a particular mode of land and water privatisation in peri-urban spaces of the Greater Accra Metropolitan Area (GAMA), Ghana. We illustrate that in the domain of land, traditional authorities tend to act as private owners rather than custodians of customary land, while in the domain of water, multiple private water providers have emerged next to the official water utility. A combined reading and analysis of these processes as forms of de facto privatisation contributes to understanding the similarities in the control over and access to land and water in peri-urban spaces. We show that in the de facto privatised control context of the peri-urban GAMA, access gained to land and water has to be actively maintained. Both gaining and maintaining access exhibit socio-economic inequalities and this is particularly so in the case of maintaining access. The article is a call for a better connection between land and water studies in order to deepen understanding of the processes at play in peri-urban spaces.     

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.     

Fostering Sustainability in Headwaters Country: Using Bioregional and Social Capital Strategies in Support of Sustainability

Abstract

Many of Canada's ex-urban and rural areas face a daunting array of sustainability challenges. In developing effective sustainability strategies, these areas must rely heavily upon local resources and capacities and existing social capital. Part of the solution for these areas may lie in multi-stakeholder collaborative approaches built on sustainability principles and strategies. These include the engagement and mobilization of civil society networks; the cultivation of strategic partnerships among key stakeholders in civil society, the private sector and government; and long-term local programmes of research, education and advocacy that are supportive of sustainability. This article describes and analyses a Canadian case study—Dufferin County, part of the Headwaters Country region in southern Ontario—in which a multi-stakeholder, civil society based approach to fostering sustainability is currently unfolding. The ideological and theoretical underpinnings of the initiative are explored, key process-oriented and substantive challenges to the approach are analysed and action research strategies are discussed.     

Evaluating the suitability of policy instruments for urban flood risk reduction

ABSTRACT

City governments have access to a range of policy instruments to reduce flood risk, but choosing among these tools is challenging. This article identifies fourteen different policy instruments that could contribute to urban flood risk reduction and draws on interviews with expert stakeholders to score these instruments across eight evaluation criteria. The results indicate which policy tools the interviewees consider to be most and least suitable and illuminate the trade-offs inherent in instrument selection. Complementary relationships between the various instruments are also considered in the context of instrument mixes – combinations of multiple policy tools designed to maximise urban flood risk reduction.     

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.     

Delivering social sustainability in the inner-city: the transformation of South-West Montreal,Quebec (Canada)

ABSTRACT

This paper analyses how social sustainability is implemented in private-led regeneration processes and which understanding of the “social” foregrounds the implementation of sustainability in Montreal. The case studies are two new residential projects led by the private sector participating in the transformation of the Southwest Borough in Montreal. The analysis is based on six components used to evaluate the operationalisation of social sustainability for new residential projects as well on the analysis of opportunities to negotiate the “social” in the implementation of sustainability. The two case studies, Griffintown and the Bassins-du-Nouveau Havre projects are examples of brownfield regeneration in a former industrial area along the Lachine Canal known as the South West Borough. We have used semi-structured interviews with the stakeholders as the main source for data collection, a review of press articles and an analysis of the principal planning documents related to each project. If the second example is more convincing in regards to the operationalisation of social sustainability, there is a lack of incentives for developers to integrate social sustainability principles in their development in the Montreal context. Planning instruments should impose more constraints on developers and municipalities should have more financial resources to negotiate with developers what the “social” should be.     

Two ways of defining sustainable mobility: Autolib’ and BeMobility

Abstract

European cities have emerged as laboratories for ‘sustainable mobility'. In the last few years, they have supported numerous electric car projects which combine clean engine technologies with offers on public or shared mobility. This paper compares two ongoing public electric car services in Berlin (BeMobility) and Paris (Autolib’). We explain how both projects shape future visions of sustainable mobility and transform regional transport systems in specific ways through their performative impact as local transport policy tools. Focusing on the socio-economic and political processes through which both projects were conceived and put into practice, we explain their differences as they reflect participating actors' interests in a French versus German industrial and transport policy context after the economic crisis in 2008. We find that whereas BeMobility integrates electric cars as one element in Berlin's intermodal transport system, and thus is centred around ‘intermodality' as the central vision of sustainable transport, Autolib’ in Paris essentially reproduces the dominant mode of private passenger car transport through adding a shared electric car fleet.     

The drivers of greenhouse gas emissions: What do we learn from local case studies?

Abstract

What can local case studies contribute to our understanding of the processes underlying the growth in greenhouse gas emissions? Since much abatement and mitigation are local in character, it is important that policy makers identify the mix of local, national and international processes that contribute to changes in greenhouse gas emissions. Drawing upon the results of case studies in Kansas, North Carolina and Ohio, how patterns of emissions in local areas can be connected analytically to the driving forces of environmental change is demonstrated. Emissions at the local level are empirically associated with the same set of trends found at national and international scale, namely, changes in population, affluence‐consumption and technology.     

Between science and local knowledge: improving the communication of climate change to rural agriculturists in the Bolgatanga Municipality,Ghana

ABSTRACT

There is an overwhelming scientific consensus that global climate is changing with associated devastating, yet differential impacts on different world regions. This, therefore, calls for efforts to improve our understanding of the phenomenon as a way of enhancing mitigation and adaptation measures. Although a lot has been done in this respect, the present study examines the extent to which misnomers associated with the calendar months and local climate events can be employed to convey the phenomenon of climate change to rural agriculturists in the Bolgatanga municipality. The study establishes that the names of the calendar months, which serve as goalposts for local agricultural practices no longer portray their true meaning due to climate change. The study, therefore, recommends the use of nuanced ways of communicating climate change to local agriculturists, using scientific research, lived experiences as well as socially and culturally embedded tools such as misnomers associated with local climate events.     

Co-Creating community gardens on untapped terrain – lessons from a transdisciplinary planning and participation process in the context of municipal housing in Vienna

ABSTRACT

Urban gardening in Vienna, Austria, has gained a new significance over the last ten years. However, although demand is constantly rising and urban gardening is being marketed in many ways, a vast majority of the urban population still has no access to gardening and its various benefits. While community gardening projects in Europe are usually viewed as temporary, self-organised bottom-up initiatives on public or abandoned private land, this case study of the Roda-Roda pilot project shows that community gardening can develop and persist even when favourable conditions for grassroots community gardens are lacking. The vast green spaces separating residential blocks (Abstandsgrün) commonly found in Vienna’s municipal housing (Wiener Gemeindebau) have a huge spatial potential for gardening, along with a forgotten tradition of self-organisation. Using an action research approach, this paper describes two principles for a successful implementation strategy under difficult conditions. Starting with a top-down approach, an interdisciplinary project team implemented a spatial and socio-economic framework that offered a stable basis for participatory community-building. As they “climbed” the ladder of participation stepwise – from exclusion to decision-making and true self-organisation – gardeners gained knowledge, skills and the self-confidence required to run a garden and create a well-working local community. At a more general level, the paper brings a co-creative planning perspective to the scientific discussion on community gardening in Europe and offers a practical approach to making local gardening opportunities available to suitable target groups by tapping into unused spatial potential.     

Methodology for CO2 chain analysis

The paper presents a methodology for CO₂ chain analysis with particular focus on the impact of technology development on the total system economy. The methodology includes the whole CO₂ chain; CO₂ source, CO₂ capture, transport and storage in aquifers or in oil reservoirs for enhanced oil recovery. It aims at supporting the identification of feasible solutions and assisting the selection of the most cost-effective options for carbon capture and storage. To demonstrate the applicability of the methodology a case study has been carried out to illustrate the possible impact of technology improvements and market development. The case study confirms that the CO₂-quota price to a large extent influence the project economy and dominates over potential technology improvements. To be economic feasible, the studied chains injecting the CO₂ in oil reservoirs for increased oil production require a CO₂-quota price in the range of 20–27 €/tonne CO₂, depending on the technology breakthrough. For the chains based on CO₂ storage in saline aquifers, the corresponding CO₂-quota price varies up to about 40 €/tonne CO₂.     

Complex property rights and Coasean bargaining in natural resource management

ABSTRACT

This paper contributes to the debate on whether private or common property rights are better for advancing the sustainable management of natural resources. This contest between public and private ownership is often exaggerated, we claim, because in the real world, complex entitlements with varying degrees of privateness/publicness prevail. Property rights belonging to families, companies, clubs, corporations, and communities are simultaneously common to the members/shareholders and private to the entities. We call these entitlements private-common entitlements. When we acknowledge this complexity, it becomes evident that neither private nor common ownership rights are alone responsible for resource depletion. Instead, depletion is caused by freeriding or evading the payment of the full price of natural resources. This invites Coase’s solution to resource allocation. Therefore, the key problem is whether and how Coasean bargaining is employed to allocate ownership over resources threatened by depletion. We contribute to the debate by showing that Coase’s approach promotes not only economically efficient but also ecologically sustainable resource management. Often, this approach would lead to the establishment of largely private property or control rights by largely collective/public entities. We apply this theoretical framework to the development of a ski resort in Pirin Mountain, Bulgaria.     

Optimization of mining by application of the equality principle

This paper shows how the equality principle can be applied to traditional mining activities as a theoretical economic basis for “environmentally friendly” waste management of natural resources. A cost structure is proposed to generally improve the exploitation of the natural resources and save energy due to the promotion of corporate economic incentives to a more cost-effective waste management related to these resources. The methodology proposed is based on the cost-benefit analysis concept. It employs the previously introduced equality principle and the model for Efficient Use of Resources for Optimal Production Economy (EUROPE) featuring shadow prices so as to optimize the mining slope and the ore-concentration when utilizing the resources of the rock and provide management with a one digit indicator of the performance of a certain mining activity to get in just once glance an instant comprehension of their mine's overall performance. This approach simultaneously improves the profitability, the technology used and the environment. A case study presents the practical application of the proposed theory on a Swedish copper mine. It is concluded that the presented methodology improves the exploitation of natural resources in mainly technological, economical and environmental terms. The methods that are developed are regarded as being suitable information support tools for decision-making in waste management and optimization of the exploitation of natural resources in the corporate and public context.     

Hyperautomobility and Governmentality in Auckland

Abstract

A number of cities around the world are associated with very high levels of private motor car usage, and Auckland provides an example of one of these ‘hyperautomobile’ cities. There are many problems with this system of transportation and dependence on the private car, including environmental, social and city design dimensions. Though there is a clear aspiration to move towards reduced levels of car usage in the city's transport and spatial planning strategies, there are major difficulties in implementation terms. We develop and consider future scenarios to 2041 to reduce these levels of motorization, and subsequent transport CO₂ emissions, with a much greater use of public transport, walking and cycling, urban planning, and low emission vehicles. The current implementability of such a ‘sustainable mobility’ future is however questioned in the current political and social context, and critically debated in terms of the available governance mechanisms and the limited attempts to shape the behaviour of the public. We conclude by calling for a reconsideration of the policy measures being considered, including the range and levels of application and investment; with a much wider framing of the transport planning remit, and carried out within a much stronger participatory framework for decision-making.     

The significance and praxis of community‐based sustainability projects: Community gardens in western Australia

Abstract

Sustainability projects initiated by community groups can be significant in their contribution to the overall process of Local Agenda 21 planning and in their substantive contribution to sustainable communities. Community gardens differ from public gardens in that they are managed by community members rather than by local governments, although they may be located on council land. Community gardens vary in type from collections of individual plots to large‐scale collaborative projects for the benefit of the wider community. Their roles include the production of fresh organic food; the creation of community places; and the use and dissemination of community science and innovative technologies. This paper reviews the types and roles of community gardens, and provides a case study of a community garden in Western Australia. It analyses the lessons learned from this particular case and the potential contribution of community gardens to Local Agenda 21 planning and to physical, ecological, sociocultural and economic sustainability.     

Increasing uptake of low impact urban design and development: The role of sustainability assessment systems

Abstract

‘Market transformation’ of the significant urban development industry towards more sustainable practices is not moving at great pace. Design and assessment systems that may promote uptake of more sustainable urban design and development are reviewed briefly followed by a comparison between building and neighbourhood scales. For the latter there is a dearth of design and assessment tools for the residential built environment and of indicators to monitor progress towards sustainable development. Local authorities increasingly require an integrated approach to data collection and inclusion of infrastructure service providers in design, assessment and monitoring of urban development and associated environmental effects. By examining attempts to increase uptake of more sustainable residential development, the potential for tools and indicators at the neighbourhood scale to reduce environmental impact of the built environment is highlighted. It is recommended that built environment initiatives need to be combined with research into behavioural changes to achieve the desired outcome of a sustainable built environment and to increase the dialogue between communities, developers and local authorities.     

Development and Experimental Study of CO2 Expander in CO2 Supercritical Refrigeration Cycles

Abstract

As one of the natural working fluids for the refrigeration system, CO₂ has been attracting increasing attention over the last ten years. But CO₂ has to work at the supercritical region for the so-called “condensation” process regarding the conventional refrigerants and evaporate at the two-phase region, and therefore results in larger throttling loss for the practical refrigeration application. Consequently, new technologies must be developed to improve the performance efficiency of the CO₂ transcritical cycle, and make it to be equal or closer to that of the refrigeration system with the conventional refrigerants. In this study, an expander is employed in the CO₂ transcritical cycle to replace the throttling valve, and as a result the throttling loss can be decreased significantly. The paper presents the development of a rolling piston expander and the activity items in the expander design, including the seal technology, the contact friction control, the suction design, etc. The performance experiments for the expander are conducted in the present testing system for the CO₂ transcritical cycle. The results show that the recovery power of the expander is related to the revolution speed of the expander. The efficiency of the expander prototype is observed to be about 32%.
