Investigating the interplay between transport, land use and the environment : a review of the literature

Integration of land use and transport decisions to achieve sustainable travel behavior has been considered an integral element for sustainable urban development. However, before the popularity of urban sustainability concept, land use and transport interaction had been scrutinized as strictly separate entities in the urban planning and development domains. Fortunately today the concept of sustainability has been pushed to the forefront of policy-making and politics as the world wakes up to the impacts of climate change and the effects of the rapid urbanization and modern urban lifestyles. The paper therefore aims to highlight the importance of the interplay between transport, land use and the environment. This review paper provides evidence from the literature including the Transport, Land Use and the Environment Special Issue contributions and global best practice cases to showcase new empirical approaches and investigations from different parts of the world that contribute to the wealth of knowledge in exploring the interplay between transport, land use and the environment thoroughly.

Increasing relevance and interest : teaching environmental and planning law to built environment students

A new approach was taken to delivering a challenging "stewarship of land" unit to over 350 predominantly first year built environment students stewardship. The new approach involved incorporating environmental and planning law into the syllabus, exposing students to a wide range of statutes, selecting legal cases according to a et of criteria and revisiting the material using different modes of delivery and teaching resources. To evaluate the effectiveness of the new approach, the students were surveyed to elicit their learning experience and preferences. The survey found that most students perceived learning about environmental and planning law, including legal cases, worthwhile.----- Areas identified by the surcey for improvement included the perception by some students that: environmenatl and planning law is irrelevant to their discipline and future caree; studying law is dull and sometimes daunting; and the prescribed reading could be omitted.----- To address student perceptions, it is proposed to reorder the topics commencing with local, charismatic topics, while explanding international content and cases, to enlarge and enhance the repertoire of video clips to include sites of legal cawses and development projects, and to reformat the online weekly quizzes to promote reading of primary material.----- Overall, the approach to teaching environmental and planning law to built environment students, including the criteria for selecting legal cases, described in this paper, was found to be effective.

Role of land use and seasonal factors in water quality degradation

Surface water and groundwater are the most important water sources in the natural environment. Land use and seasonal factors play an important role in influencing the quality of these water sources. An in-depth understanding of the role of these two influential factors can help to implement an effective catchment management strategy for the protection of these water sources. This paper discusses the outcomes of an extensive research study which investigated the role of land use and seasonal factors on surface water and groundwater pollution in a mixed land use coastal catchment. The study confirmed that the influence exerted on the water environment by seasonal factors is secondary to that of land use. Furthermore, the influence of land use and seasonal factors on surface water and groundwater quality varies with the pollutant species. This highlights the need to specifically take into consideration the targeted pollutants and the key influential factors for the effective protection of vulnerable receiving water environments.

Early land grants and reservations : Any lessons from the Queensland experience for the sustainability challenge to land ownership

Environmentalists have called for a new property paradigm premised on the idea of land ownership as a delegated responsibility to manage land and resources for the public benefit. An examination of Crown freehold grants from the beginnings of settlement until the 1890s in Queensland shows that fee simple titles were granted subject to express conditions and reservations designed to reserve useful natural resources to the Crown, and to promote public purposes. Over time, legislative regulation of landowner’s rights rendered obsolete the use of express conditions and reservations in grants. One result of this change was that the inherently limited nature of fee simple ownership, and the communal obligations to which it is subject, are less transparent than in colonial times.

Emerging urban futures, land, water, infrastructure

This paper will examine the intersection of design research and problem‐based teaching through the process and outcomes of a four year long ARC funded research project: the Emerging Futures Project. Sustainability is central to the project; in its overall content as well as in the broad aim of determining better outcomes for urban consolidation.   

Australia and New Zealand CBNG development and environmental implications

Following the success of Coalbed Natural Gas (CBNG) operations in the United States, companies in Australia and New Zealand have been actively exploring and developing this technology for the last two decades. In particular, the Bowen and Surat basins in Queensland, Australia, have undergone extensive CBNG development. Unfortunately, awareness of potential environmental problems associated with CBNG abstraction has not been widespread and legislation has at times struggled to keep up with rapid development. In Australia, the combined CBNG resource for both the Bowen and Surat basins has been estimated at approximately 10,500 PJ with gas content as high as 10 m3/tonne of coal. There are no official estimates for the magnitude of the CBNG resource in New Zealand but initial estimates suggest this could be up to 1,300 PJ with gas content ranging from 1 to 5 m3/tonne of coal. In Queensland, depressurization of the Walloon Coal Measures to recover CBNG has the potential to induce drawdown in adjacent deep aquifer systems through intraformational groundwater flow. In addition, CBNG operators have been disposing their co-produced water by using large unlined ponds, which is not the best practice for managing co-produced water. CBNG waters in Queensland have the typical geochemical signature associated with CBNG waters (Van Voast, 2003) and thus have the potential to impair soils and plant growth where land disposal is considered. Water quality from exploration wells in New Zealand exhibit the same characteristics although full scale production has not yet begun. In general, the environmental impacts that could arise from CBNG water extraction depend on the aquifer system, the quantity and quality of produced water, and on the method of treatment and disposal being used. Understanding these impacts is necessary to adequately manage CBNG waters so that environmental effects are minimized; if properly managed, CBNG waters can be used for beneficial applications and can become a valuable resource to stakeholders.

Human rights and environmental wrongs : achieving environmental justice through human rights law

The links between the environment and human rights are well established internationally. It is accepted that environmental problems impact on individuals’ and communities’ enjoyment of rights which are guaranteed to them under international human rights law. Environmental issues also impact on governments’ capacity to protect and fulfil the rights of their citizens. In addition to these links between the environment and human rights, it is argued that human rights principles offer a strategy for addressing environmental injustice. The justice implications of environmental problems are well documented, with many examples where pollution, deforestation or other degradation disproportionately impacts upon poorer neighbourhoods or areas populated by minority groups. On the international level, there are environmental injustices which exist between developed and developing states. Further, there are also potential injustices for future generations. This paper investigates the role of human rights principles in addressing these instances of environmental injustice, and argues that the framework of human rights norms provides an approach to environmental governance which can help to minimise injustice and promote the interests of those groups who are most adversely affected. Further, it suggests that the human rights enforcement mechanisms which exist at international law could be utilised to lend more weight to claims for more equitable environmental policies.

Inadequacy of land use and impervious area fraction for determining urban stormwater quality

Urban stormwater quality is multifaceted and the use of a limited number of factors to represent catchment characteristics may not be adequate to explain the complexity of water quality response to a rainfall event or site-to-site differences in stormwater quality modelling. This paper presents the outcomes of a research study which investigated the adequacy of using land use and impervious area fraction only, to represent catchment characteristics in urban stormwater quality modelling. The research outcomes confirmed the inadequacy of the use of these two parameters alone to represent urban catchment characteristics in stormwater quality prediction. Urban form also needs to be taken into consideration as it was found have an important impact on stormwater quality by influencing pollutant generation, build-up and wash-off. Urban form refers to characteristics related to an urban development such as road layout, spatial distribution of urban areas and urban design features.

Environmental law and the economic impact on Australian firms

In response to international awareness of environmental issues and the inadequacies of common law actions, legislation has been enacted by Australian governments to facilitate environmental protection. The Environmental Protection Act 1994 (Qld) and accompanying Environmental Protection (Interim) Regulation 1995 (Qld) is one example of government response to mounting public pressure to legislate for the environment. Investigation into the operation of the legislation exposes the costs faced by Australian firms in its application. The legislation identifies a number of environmentally relevant activities and imposes licensing and reporting requirements on firms undertaking such activities. In view of these legislative requirements and the increasing public awareness of environmental issues over the last decade in Australia, it could be expected that firms undertaking environmentally sensitive activities will place greater importance on the management of environmental issues. If so, the greater prominence placed on environmental management may be reflected in disclosures made by the firm to its shareholders and other interested parties. This article investigates the type and extent of costs currently imposed by the body of environmental laws in Australia with the discussion primarily focusing upon costs imposed due to the operation of environmental legislation in Queensland. Further, the article reports empirical analysis of management response to environmental issues where firms are undertaking environmentally sensitive activities.

Human rights and environmental wrongs : achieving environmental justice through human rights law

The numerous interconnections between the environment and human rights are well established internationally. It is understood that environmental issues such as pollution, deforestation or the misuse of resources can impact on individuals’ and communities’enjoyment of fundamental rights, including the right to health, the right to an adequate standard of living, the right to self‐determination and the right to life itself. These are rights which are guaranteed under international human rights law and in relation to which governments bear certain responsibilities. Further, environmental issues can also impact on governments’ capacity to protect and fulfil the rights of their citizens. In this way human rights and environmental protection can be constructed as being mutually supportive. In addition to these links between the environment and human rights, human rights principles arguably offer a framework for identifying and addressing environmental injustice. The justice implications of environmental problems are well documented and there are many examples where pollution, deforestation or other degradation disproportionately impact upon poorer neighbourhoods or areas populated by minority groups. On the international level, environmental injustice exists between developed and developing States, as well as between present and future generations who will inherit the environmental problems we are creating today. This paper investigates the role of human rights principles, laws and mechanisms in addressing these instances of environmental injustice and argues that the framework of human rights norms provides an approach to environmental governance which can help to minimise injustice and promote the interests of those groups which are most adversely affected. Further, it suggests that the human rights enforcement mechanisms which exist at international law could be utilised to lend weight to claims for more equitable environmental policies.

The compatibility of leasehold and freehold tenure arrangements with environmental offset and trading initiatives

Environmental offsets and environmental trading initiatives are being rapidly introduced into environmental regulatory regimes. These relatively new legal mechanisms are attempting to fill in the gaps left by command and control regulation. The introduction of environmental offset and trading policy in Queensland will need to be compatible with existing land tenure regulation. Who owns and who uses natural resources are controlled by a range of legislative reservations and restrictions. Reservations give the State ownership of certain natural resources such as minerals, quarry material and, in some circumstances, forest products. Where there is a reservation in operation, the land holders rights are weakened. Restrictions in relation to uses prevent land holders from carrying out certain activities on the land. An example of a restriction of use is the operation of the Vegetation Management Act 1999(Qld), which prescribes the manner in which vegetation is to be dealt with. This article explores the nature of freehold and leasehold land tenure in Queensland and examines the effect of reservations and restrictions upon the operation of environmental offset and trading initiatives. Presently Queensland legislation does not directly address the relationship between land tenure and environmental offset and trading initiatives. The stability of tenure required for the creation of environmental offsets can be at odds with the flexibility allowed for under leasehold arrangements. This flexibility may act to undermine the permanency requirement of environmental offset creation (i.e. the guarantee that the offset is created for the long term).
