Importance of public information and perception for managing recreational activities in the Peel-Harvey estuary, Western Australia

Surveys of water recreational activities were conducted in the Peel-Harvey estuary. Channels used by recreationists to gain information about water quality, the perception of water quality and resulting behaviour were investigated. This study showed that personal perception, local knowledge and history, absence of warnings and residency were major factors contributing to risk perception and behaviour in this recreational community. Management strategies should take this information into account to achieve maximal outcomes.     

Regulatory challenges to the implementation of carbon capture and geological storage within the European Union under EU and international law

Carbon dioxide capture and storage (CCS) is a relatively new technology in the context of climate change mitigation strategies, and its legal and regulatory implications are not yet broadly understood. This paper takes a brief look at international environmental law principles relevant to CCS, identifies key environmental and safety risks associated with the technology, and highlights significant legal frameworks that pose challenges to the implementation of CCS within the EU under EU and international law. It then notes continuing regulatory gaps that will need to be addressed for large-scale CCS to take place. The paper concludes that the clear inclusion or exclusion of CCS activities from the range of relevant legal frameworks will increase transparency, provide regulatory certainty and ultimately facilitate CCS in appropriate contexts.     

Interactive environmental planning: creating utopias and storylines within a mobilities planning project

This article presents a research project on mobility management in Danish municipalities aimed at creating more sustainable mobilities. The project, called Formula M (2011–2014), worked within sciences, public and private sectors, and civil society. Often contemporary projects in both planning and designing sustainable mobilities fall short when it comes to changing praxis to limit CO₂ emissions, where they just concentrate on technocratic elements. They often neglect the ‘why’ and ‘for what’ which is needed in order to drive such change. In the Formula M project, focus has been on supporting the planners involved in the project on their ‘why’ and ‘for what’. Based on a theoretical understanding of relational and collaborative planning the article contributes to an understanding of which approaches and methods can be used to facilitate the relationships and dialogues between many actors. Methodologically, this has been sought through a specific focus on the role of utopias as a tool for storytelling.     

Legal and regulatory challenges in the implementation of CO2 geological storage: An Alberta and Canadian perspective

Alberta is the province with the largest CO₂ emissions in Canada, with approximately two-thirds of emissions originating from large stationary sources. Due to the fortuitous association of large CO₂ sources with the storage capacity offered by the underlying Alberta basin, it is expected that large-scale CO₂ geological storage in Canada will occur in Alberta first, and both levels of governments are contemplating measures to facilitate implementation. A review of the current provincial and federal legislation and regulations presented in this paper indicates that the existing legal and regulatory regime is reasonably sufficient, with some modifications, to accommodate the active injection phase of CO₂ capture and storage (CCS) operations, and the early takers of this new technology. However, governments in Alberta and Canada, and likely everywhere, need to address several pressing issues dealing mainly with the CCS post-operational phase. These issues, reviewed in this paper from an Alberta and Canadian perspective, fall into several categories: jurisdictional, property (ownership), regulatory and liability. Because Alberta is a landlocked province, matters relating to CO₂ storage under the seabed will not be addressed here except when discussing matters of jurisdiction and CO₂ classification. Possible models for post-injection liability transfer to the state are also presented. Although this review is focused on western Canada conditions, the issues are broad enough to be of interest in other jurisdictions, which may also adopt parts of the legal and regulatory framework that is quite well developed in Alberta.     

Permitting issues for CO2 capture,transport and geological storage: A review of Europe,USA, Canada and Australia

The paper reviews the environmental, health and safety permitting/regulatory issues presented by CO₂ capture and storage (CCS) operations across the full project cycle, and reviews existing regulations in the EU, North America and Australia to assess their applicability to CCS, and identify regulatory gaps.     

Spatial planning and changing landscapes: a failure of policy in peri-urban Victoria,Australia

Building on the scientific literature, this article first summarises the socio-environmental impacts of land-use change expected to occur in high amenity Australian peri-urban areas, involving in particular, the effects of land development on agriculture, biodiversity, landscape character, bushfire risk and social factors. Second, the current spatial planning framework and its distribution in seven municipalities in Victoria, Australia, is critically analysed, and records of approved planning permits are related to this framework to assess the challenges posed by peri-urban growth. We argue that the current planning framework supports a static approach which does not address foreseen challenges and lacks strategic power. Both the strategic framework and the development approval process lead to unanticipated, cumulative impacts and contestation. A more coordinated, less urban-centric approach to planning and the introduction of rural land-use plans would substantially address some of the issues encountered.     

Policy design,spatial planning and climate change adaptation: a case study from Australia

There are gaps in the existing climate change adaptation literature concerning the design of spatial planning instruments and the relationship between policy instruments and the sociopolitical barriers to adaptation reform. To help address this gap, this article presents a typology of spatial planning instruments for adaptation and analyses the pattern of instrument choice in Australian planning processes in order to shed light on contextual factors that can impede adaptation. The analysis highlights how policy design can amplify the barriers to adaptation by arranging policy actors in ways inimical to reform and stripping decision makers of the instruments necessary to make and sustain desired policy changes.     

Resilience to heat in public space: a case study of Adelaide,South Australia

During summer heatwaves, heat load exacerbates in urban heat islands (especially in hot climates) and threatens public life in cities. This paper examines the links between urban microclimates, outdoor thermal discomfort and public life through an exploratory case study. Heat resilience is highlighted as the ability of the space to support its normal activities when experiencing out-of-comfort temperatures. It also reports on the correlations between heat sensitive outdoor activities and urban greenery in three disparate case studies in Adelaide. Results indicate that necessary and optional activities start to decline after the apparent temperature reaches the threshold of 28?°C–32 °C, while activities in public spaces with more urban greenery show higher resilience to heat stress. Research findings propose heat resilience as a quality indicator in public space and support the application of urban greenery to make urban settings more resilient to heat stress.     

First assessment of sources and sinks for carbon capture and geological storage in Portugal

A preliminary study for a source–sink match for application of Carbon Capture and Storage (CCS) in Portugal is presented. The location of the main CO₂ emission sources in Portugal, existing and planned, was analysed and three main source clusters, emitting a total of 26.8 Mt/year, were defined. The three source clusters are connected by a natural gas pipeline network.CO₂ storage reservoirs are likely to be restricted to deep saline formations. Potential storage formations are described in the Porto, Lusitanian and Algarve sedimentary basins. Due to the large continental shelf, composed mainly of sedimentary rocks, it is important to consider offshore opportunities. A Geographical Information System (GIS), including information on the stratigraphy, seismicity, neotectonics and geothermal features, was used for prioritising the areas where reservoir identification and characterization studies should be conducted. Despite not showing the most promising geological conditions, the area around the deepwater harbour of Sines is given the highest priority, since sources in the area account for more than 40% of point source emissions in Portugal.     

An empirical study on the public perception and acceptance of hydrogen energy in Taiwan

In this study, we extract factors by using factor analysis and then adopt them in a regression analysis to investigate the public perception and acceptance of hydrogen energy in Taiwan. Six reliable factors were extracted from the exploratory factor analysis of 29 5-point Likert-type items. Our regression results show that the public perception of hydrogen energy as a green energy, public belief in domestic hydrogen industries being able to conform to international safety standards, and public perception of the cost advantage of hydrogen gas over petroleum have significantly positive effects on support for the development of hydrogen energy in Taiwan. While people have a high level of concern about the safety of hydrogen and its associated technologies, the unsafe perceptions of hydrogen and its associated technologies have no significant effects on their support. In particular, public belief in domestic hydrogen industries being able to conform to international safety standards is a powerful factor that enhances support for hydrogen energy development.     

Benefits and challenges of using an Assessment of Ecosystem Services approach in land-use planning

This research investigates the use of an Assessment of Ecosystem Services (AES) approach as a planning tool in Florida through the use of an online survey. Target respondents were professionals who had been involved in AES projects. The majority of the respondents perceive an AES approach as a comprehensive and holistic approach that results in better land-use planning decisions. However, AES does not appear to be widely used to guide planning decisions. Despite some challenges, respondents across multiple agencies and institutions in Florida are supportive of using AES in combination with traditional land-use planning tools. More rigorous testing and validation and clarification of guidelines for best practice could improve political and economic support and thereby facilitate the use of AES to guide land-use planning efforts.     

The call of different wilds: the importance of definition and perception in protecting and managing Scottish wild landscapes

Concepts of wild land have recreational, ecological and cultural dimensions, and place varying emphasis on physical landscape attributes and the perceptions of users. In Scotland, national and NGO policies show reasonable consistency in interpreting and defining ‘wild land’, emphasising the (perception of) lack of current human influence as a key criterion. This research used semi-structured interviews with key individuals and a questionnaire survey of land managers to evaluate concepts and perceptions of wild land in Scotland. Recognising that the conceptual and spatial definition of wild land is a key issue, a new typology is proposed. Weaknesses in the policy framework, as well as key potential threats to, and opportunities associated with, wild landscapes are identified. Management initiatives are fitted to the typology and divided into four management themes. Key recommendations are: (i) that national policy for wild landscapes needs to incorporate criteria, which recognise the multiple values deriving from such areas; and (ii) that future research should combine user group preferences with physical attribute information in determining what constitutes wild landscapes.     

Regulatory resistance to environmental law in rural Australia: land clearing,murder and the media

ABSTRACT

In 2014 an Australia public servant was killed in a confrontation over illegal land clearing. The perpetrator was a land holder with a history of non-compliance with environmental regulations and had been subject to a series of prosecutions. Political suggestions that the crime was somehow justified drew attention to the growing prevalence of law breaking linked to environmental law and policy in rural Australia. This paper investigated the social construction of both the crime and the community response through a qualitative media content analysis. Utilising the “Recipe for Criminalisation” framework developed by Amnesty International, the analysis identified a contest between media discourses of legitimacy in regards to the actions taken by the perpetrator, the public servant and ultimately, the regulatory framework itself. The analysis revealed that the link between media references to illegitimate legislation, excessive regulation, over-zealous compliance and strong social norms of rural independence and economic survival created a persuasive story of justified resistance to unwelcome environmental legislation in this case. Understanding how affected communities respond to instances of policy failure, civil and criminal law breaking and environmental compliance is a crucial factor in designing more legitimate and effective governance regimes. How media narratives are constructed, by whom and in whose interests remains an important analytic question for the study of resistance to environmental law and policy around the world.     

The use of residential water consumption as an urban planning tool: a pilot study in Adelaide

This paper examines the water consumption patterns for different types of residential dwellings and areas in Adelaide, Australia. The method uses datasets regularly collected and maintained by a number of organizations to allow water consumption patterns to be analyzed and examined over time. The results suggest that water consumption varies between different types of residential dwellings, and areas, and that using metropolitan averages to measure national consumption patterns can be misleading. Importantly, the results suggest that per capita consumption is not significantly different between different types of dwellings. The ability to analyze water consumption patterns at the local level would enable planners and managers to better target initiatives aimed at reducing water consumption, and would also give planners a new tool to assess planning and environmental policies.     

Coupling of geochemical reactions and convective mixing in the long-term geological storage of carbon dioxide

The effect of coupling of geochemical reactions with convective mixing of dissolved carbon dioxide during geological storage is investigated by both analytical and numerical techniques. In the limit of fast reactions, scaling arguments and stability analysis show that the time for the onset of convection could be increased by up to an order of magnitude due to consumption of the dissolved carbon dioxide in mineralization. Numerical simulations are then used to investigate the effect of general reaction rates in two contrasting mineralogies, including overall dissolution and the distribution of ion and mineral concentrations.     

Tourism in the high north: Management challenges and recreation opportunity spectrum planning in Svalbard,Norway

The Arctic is subject to considerable pressure from a rapidly expanding world tourism industry and increasing demands for oil and gas resources. The archipelago of Svalbard in the Norwegian high arctic contains the most accessible islands in the entire Arctic, but despite extensive use of the resources, they still contain some of the last true wilderness lands in Europe. The growth in tourism with visitors from all parts of the world combined with coal mining and oil and gas exploration call for a coordinated environmental policy. A research-based management plan for tourism and recreation has now been developed. Some management problems were encountered in designing a recreation opportunity spectrum plan for this extremely vulnerable environment. Although Svalbard in many ways is a unique area, the challenges to management are comparable to those found in regions further south.     

Evaluating geological sequestration of CO2 in bituminous coals: The southern Sydney Basin,Australia as a natural analogue

Carbon dioxide contents of coals in the Sydney Basin vary both aerially and stratigraphically. In places, the coal seam gas is almost pure CO₂ that was introduced from deep magmatic sources via faults and replaced pre-existing CH₄. In some respects this process is analogous to sequestration of anthropogenic CO₂. Laboratory studies indicate that CO₂:CH₄ storage capacity ratios for Sydney Basin coals are up to ∼2 and gas diffusivity is greater for CO₂ by a factor of up to 1.5.Present-day distribution of CO₂ in the coals is controlled by geological structure, depth and a combination of hydrostatic and capillary pressures. Under present-day P–T conditions, most of the CO₂ occurs in solution at depths greater than about 650 m; at shallower depths, larger volumes of CO₂ occur in gaseous form and as adsorbed molecules in the coal due to rapidly decreasing CO₂ solubility. The CO₂ has apparently migrated up to structural highs and is concentrated in anticlines and in up-dip sections of monoclines and sealing faults. CO₂ sequestered in coal measure sequences similar to those of the Sydney Basin may behave in a similar way and, in the long term, equilibrate according to the prevailing P–T conditions.In situ CO₂ contents of Sydney Basin coals range up to 20 m³/t. Comparisons of adsorption isotherm data measured on ground coal particles with in situ gas contents of Sydney Basin coals indicate that the volumes of CO₂ stored do not exceed ∼60% of the total CO₂ storage capacity. Therefore, the maximum CO₂ saturation that may be achieved during sequestration in analogous coals is likely to be considerably lower than the theoretical values indicated by adsorption isotherms.     

Informed and uninformed public opinions on CO2 capture and storage technologies in the Netherlands

Two research methods were used in this study to analyze the awareness and perception of the Dutch general public regarding Carbon dioxide Capture and Storage (CCS). In an Information-Choice Questionnaire (ICQ), a representative sample of the Dutch public (n = 995) was provided with all information on attributes of six CCS options, which experts deemed necessary to come to well-considered and well-informed opinions. A traditional questionnaire was used simultaneously (n = 327) to study uninformed evaluations of these technologies. The results showed that the Dutch public is mostly unaware of CCS and has little knowledge about how current energy use causes global warming. Uninformed respondents are still inclined to give their opinion however, which results in unpredictive, easily changeable opinions. ICQ respondents who processed information on attributes of CCS options were likely to base their option evaluations on this information, though not entirely. All in all, the results of the ICQ suggest that, after processing information deemed necessary by experts, Dutch people reluctantly agree with large scale implementation of each of the six CCS options.
