Sustainability assessment is emerging as a form of impact assessment with the concept of sustainability at its heart. This thesis contributes to the process of theory-building for sustainability assessment through an exploration of the development of this policy tool within the Western Australian context. Through an analysis of the sustainability assessments of the Gorgon gas development on Barrow Island and the South West Yarragadee water supply development, and a process of personal reflection, I explore the potential of sustainability assessment to contribute to a more sustainable society by facilitating learning. While the focus of traditional forms of impact assessment has typically been ‘exterior’ forms of knowledge and learning relating to the potential impacts of a proposal, or to process methodologies and governance arrangements, in this thesis I argue that sustainability assessment processes should also facilitate ‘interior’ forms of learning that excavate and challenge underpinning assumptions about the organisation of society, including shared discourses and storylines, as well as personal views and beliefs. To achieve this aim, I maintain that sustainability assessment should be a proactive process that is integrated with the proposal development, framed by an open question and guided by a ‘sustainability decision-making protocol’ that operationalises sustainability for the decision at hand. It should be guided by a structured process framework that assures attention is given to issues that might otherwise be neglected. Each step of the process framework should represent a space for inclusive deliberation, with the concept of sustainability itself acting as a catalyst for learning and reflexivity. Located within the institutions of modern industrial society, deliberative sustainability assessment processes can contribute to the emergence of an 'integral sustainability' that embraces and reconnects the interior and exterior, collective and individual dimensions of policy-making and of society in general. The influence of sustainability assessment can thus extend beyond the immediate decision at hand to contribute to a momentum for societal change towards a more sustainable future.

Globally plantation forestry plays a pivotal role in terms of timber production, ecological services and maintaining local livelihoods. In South Africa commercial forestry occupies a relatively small portion of the total land area, but contributes significantly towards the national GDP. Forestry had been labelled as a streamflow reduction activity. Thus further afforestation is not possible. It is of paramount importance that plantations are managed on a sustainable basis in order to meet future timber demands. However, sustainability goes beyond the replenishment of natural resources or economic prosperity and also includes social responsibility. (CSR) initiatives are a means for companies to maximize the positive contribution their operations can make to the promotion of fair work practices and ecological sustainability. Plantations are mostly located in rural areas and often reflect the only form of local employment. Often employees are at risk of economic exploitation and high risk of injury while little scope for economic and educational betterment exists. CSR incorporates people, planet and profit. It is important to fulfil the basic needs of the workers in order for the company to realize environmental and economic prosperity. It is the aim of this study to highlight the essential role of people in insuring the long-term sustainability of the Western Cape plantations. The primary aim of this study is to investigate the over-all well-being of forestry workers in the Western Cape plantations. In order for people to reach the over-all goal of the organization, they first need to satisfy their basic needs. More often than not this is the case with forestry workers. Some of the issues that negatively impact on their over-all wellbeing are:  Their working environment and conditions  Lack of investment in resident / neighbouring communities  Lack of adequate stakeholder consultation  Poor standards of worker accommodation If companies wish to be sustainable, they need to address these issues that forest workers are being confronted with. The secondary aim of this study is to explore CSR initiatives that could address these issues in the Western Cape plantation villages.This study deploys a mixed approach, using both qualitative and quantitative methods. Data were collected through the distribution of structured questionnaires, interviews, meetings, company documents and reviewed literature. The research shows that the social issues that confront forest villages include poor sanitation facilities, lack of home ownership, poor state of worker accommodation, lack of extramural activities, substance abuse and relatively low remuneration rates. The company also faces challenges with regards to the implementation of its CSR programme. This study makes several recommendations which are based on the findings. One such recommendation is a tripartite approach to CSR. Here a tripartite approach refers to the partnership between the company, Government and civil society.

[Truncated abstract] Insufficient water use by annual crop and pasture species leading to costly rises in saline watertables has prompted research into potentially profitable deep-rooted perennial species in the Western Australian wheatbelt. Native mallee eucalypts are currently being developed as a short-rotation coppice crop for production of leaf oils, activated carbon and bio-electricity for low rainfall areas (300—450 mm) too dry for many of the traditional timber and forage species. The research in this study was aimed at developing a knowledge base necessary to grow and manage coppiced mallee eucalypts for both high productivity and salinity control. This firstly necessitated identification of suitable species, climatic and site requirements favourable to rapid growth, and understanding of factors likely to affect yield of the desirable leaf oil constituent, 1,8-cineole. This was undertaken using nine mallee taxa at twelve sites with two harvest regimes. E. kochii subsp. plenissima emerged as showing promise in the central and northern wheatbelt, particularly at a deep acid sand site (Gn 2.61; Northcote, 1979), so further studies focussed on physiology of its resprouting, water use and water-use efficiency at a similar site near Kalannie. Young E. kochii trees were well equipped with large numbers of meristematic foci and adequate root starch reserves to endure repeated shoot removal. The cutting season and interval between cuts were then demonstrated to have a strong influence on productivity, since first-year coppice growth was slow and root systems appeared to cease in secondary growth during the first 1.5—2.5 years after cutting. After decapitation, trees altered their physiology to promote rapid replacement of shoots. Compared to uncut trees, leaves of coppices were formed with a low carbon content per unit area, and showed high stomatal conductance accompanied by high leaf photosynthetic rates. Whole-plant water use efficiency of coppiced trees was unusually high due to their fast relative growth rates associated with preferential investments of photosynthates into regenerating canopies rather than roots. Despite relatively small leaf areas on coppice shoots over the two years following decapitation, high leaf transpiration rates resulted in coppices using water at rates far in excess of that falling as rain on the tree belt area. Water budgets showed that 20 % of the study paddock would have been needed as 0—2 year coppices in 5 m wide twin-row belts in order to maintain hydrological balance over the study period. Maximum water use occurred where uncut trees were accessing a fresh perched aquifer, but where this was not present water budgets still showed transpiration of uncut trees occurring at rates equivalent to 3—4 times rainfall incident on the tree belt canopy. In this scenario, only 10 % of the paddock surface would have been required under 5 m wide tree belts to restore hydrological balance, but competition losses in adjacent pasture would have been greater

Tourism does not operate in a predictable and mechanistic environment and is influenced by unpredictable circumstances. Influences include underlying values and perceptions keeping the system unpredictable and dynamic. Tourism that utilises natural resources is exposed to the additional unpredictability of natural changes and activities and/or decisions of other stakeholders. Tourism research generally adopts reductionist approaches and has not effectively understood tourism as a stakeholder within a complex system of stakeholders. Reductionist approaches have led to interpretations of sustainable tourism development being highly focused and sector specific limiting understanding of the complex systems in which tourism operates and resulting in narrow perspectives. To understand underlying elements influencing the system, a new paradigm is required.

Attaining the ‘appropriate’ balance between human use of national parks and their protection is a topic of considerable public, scientific and business interest and is thus an important focus for research. An increasingly affluent and mobile western society has made tourism the world’s largest industry; an industry with a significant reliance on the attractions of protected areas such as national parks and their wildlife. Regional communities have benefited from protected areas through local tourism expenditure and government recognition of the economic and social values realized from protected areas. High levels of visitation, and the management of this human use require effective management. But tensions arise when park managers invoke policies and management prescriptions to mitigate the adverse affects of human use. These actions and the way they are implemented can have an alienating impact on local communities, particularly those with a direct business dependency on park tourism. This thesis explores the notion that truly sustainable management of national parks can only be achieved if park managers and communities living adjacent to parks work together in a partnership to meet each other’s needs and through this process, foster the long-term environmental, social and economic benefits that can be derived from these parks. This thesis documents how a local community perceives its park managers and thereby the impact that park management has on local communities. It then seeks to identify the opportunities for park managers and communities to improve the way they view each other and the skills, attitudes and approaches necessary to create the environment for a sustainable relationship and can deliver sustainable outcomes for both parties.
Three methods were employed to progress this research; an extensive review of literature and theory on relevant aspects of the people and parks relationship; the use of a case study of communities adjacent to parks on the Ningaloo Coast; and, qualitative and quantitative surveys to inform those case studies. A resident perception survey of the Exmouth and Coral Bay communities was conducted in August 2005. At the same time key stakeholder representatives were interviewed. Secondary quantitative data on the areas economy and demographics was also collected to triangulate aspects of the primary data. The Ningaloo coast community’s perception of park management has been adversely affected by a recent (2004) management planning process for Ningaloo Marine Park that culminated in significant constraints being placed on recreational fishing access. Both the planning process and the decision have been the focus of community anger. Currently the levels of trust and respect within the community for the park agency and its management performance are low. Despite evidence that the parks of the Ningaloo coast make important social and economic contributions to the local communities of this area, the local community holds negative perceptions of the social and economic impacts of park management, and are influenced strongly by the local community’s attitudes, perceptions and feelings towards the park agency. The park agency’s inability to consult, involve and communicate with the local community (to the satisfaction of the local community) contributes to these attitudes, feelings and perceptions.
Key findings include; the prevailing norms and belief systems within the park agency reinforce the classic managerial paradigm; park management fails to accommodate broader social and economic measures, which diminishes trust and undermines attempts to foster community involvement and stewardship; ineffectual leadership, poor communication and outmoded approaches to planning and community engagement, local apathy to involvement in park planning and a lack of community education in regard to the promotion of park values, programs and activities compound this situation. The Ningaloo coast has the potential to provide an exceptionally bright future for its local communities, based largely on the inherent natural and cultural values of Ningaloo Marine Park, Cape Range National Park and other associated reserves. Whether the potential to develop community stewardship of the parks of the Ningaloo coast is fully met depends largely on the willingness of park management to relinquish some of its power, establish a suitable governance model in order to work collaboratively with the community and communicate effectively with it in order to achieve sustainable futures for both the park and the community.

Over the past 30 years in Western Australia (WA), there has been a heated debate about the future use of the remaining temperate old-growth forests of karri and jarrah in the south-west of the State. This debate revolved around policy proposals from two social movements: one social movement wanted to preserve as much of the remaining old-growth forests as possible, and an opposing social movement supported a continued ‘sustainable’ logging of the forests for hardwood products. This research project undertook a comparative case study analysis of Australia (TCA) on the pro-logging side and Liberals For Forests (LFF) on the anti-logging side. It drew on a macro-level European theoretical approach (New Social Movement theory) and a US organizational approach (Resource Mobilisation Theory). The study also investigated the extent to which these two social movement organisations (SMOs) had been effective in Over the past 30 years in Western Australia (WA), there has been a heated debate about the future use of the remaining temperate old-growth forests of karri and jarrah in the south-west of the State. This debate revolved around policy proposals from two social movements: one social movement wanted to preserve as much of the remaining old-growth forests as possible, and an opposing social movement supported a continued ‘sustainable’ logging of the forests for hardwood products. This research project undertook a comparative case study analysis of one WA organisation from each of these two social movements- Timber Communities Australia (TCA) on the pro-logging side and Liberals For Forests (LFF) on the anti-logging side. It drew on a macro-level European theoretical approach (New Social Movement theory) and a US organizational approach (Resource Mobilisation Theory). The study also investigated the extent to which these two social movement organisations (SMOs) had been effective in influencing the development of State forest policy. For this purpose Schumaker’s (1975) framework for judging the political effectiveness of social movements was used. The key research problem investigated in this thesis is why these two SMOs continued to debate the forest policy issue after more than 30 years of public controversy? Interviews with a key range of stakeholders were the key research method of this study. Additionally, an investigation into important economic and social changes in the south west was undertaken using census and other data between 1971 and 2001 and this was supported by an historical analysis of the timber industry in WA’s south west. Finally, a 3-year study of the reporting of forest issues by two local and one national newspaper was completed. The 1998-2000 period was chosen for the newspaper analysis as this was when the new Regional Forest Agreement was being finalised. This research shows that new values toward the old-growth forests developed among the WA public over the past 30 years and this has created an unbridgeable policy gap between those such as the TCA who wanted the past policies to continue and those such as the LFF who wanted to preserve the remaining native forests. ABS data confirm that the south-west region of WA changed dramatically between 1970 and 2000 as the wine and tourism industries developed and that these changes were different to those occurring in the other wine regions and non-city areas of Australia. As the population increased in this region, a key segment attracted by these new employment opportunities were middle class, well-educated people with new values toward the natural environment. The interview and newspaper article data clearly showed that the debate in WA in the late 1990s over the proposed RFA provided a new political opportunity for the anti-logging movement to raise their concerns and to establish a renewed public debate about the appropriateness of the WA forest policies. This came at a time when the traditional policy power of the timber industry stakeholders and the government department in charge of the forests (Conservation And Land Management) had been dramatically diminished. The combination of these factors led to the election of the new ALP government and the introduction of a new, non-logging policy for WA’s old-growth native forests.

[Truncated abstract] The application of reductionism, breaking down problems to simpler components that can be solved and then aggregating the results, is one of the bases of classical science. However, living organisms, ecosystems, social and economic structures are complex systems, characterised by non-linear interactions between their elements and exhibit emergent properties that are not directly traceable to their components. Sustainability assessment frameworks oversimplify system interactions, achieving limited predictive capacity and causing managerial behavior that may reduce system's ability to adapt to external disturbance. Intrigued by the importance of complexity, we explore the central theme of how complex thinking can influence the understanding and progress towards sustainability. The purpose is to conceptualize the relationship of key terms (such as sustainability, functionality and resilience), and consecutively develop new or adjust existing sustainability frameworks to take into account complex systems interactions. We aim at developing theory and frameworks that can be used to raise awareness of the pitfalls of the growth paradigm and direct towards modest positions when managing complex systems. We seek to define the structural elements that influence system adaptive capacity, allowing identification of early signs of system rigidity or vulnerability and the development of knowledge and techniques that can improve our predictive and managerial ability. The focus has been on a variety of system scales and dynamics. At the collective community level, a number of stakeholder engagement practices and frameworks are currently available. However, there is limited awareness of the complexity challenges among stakeholders, who are commonly directed to a triple bottom line analysis aiming at maximizing a combination of outputs. An attempt is conducted to measure the functionality of the processes underlying a standing stock, in contrast to sustainability measures that only assess the variations of the standing stock itself. We develop the Index of Sustainable Functionality (ISF), a framework for the assessment of complex systems interactions within a large-scale geographic domain and apply it to the State of Western Australia. '...' Finally, we focus on smaller systems scales and develop a methodology for the calculation of Product Ecological Footprint (PEF) including elements from the accounting method of activity based costing. We calculate PEF for three apple production systems and identify significant differences from first stage calculations within the same industry. Cross-industry application will provide a practical way to link individuals' consumption with their ecological impact, reduce misperceptions of products' ecological impacts and develop a market-driven approach to internalizing environmental externalities. At the firm level PEF can be compared with investment costs, resulting in the opportunity to optimize both functions of financial cost and ecological impact in decision making. We have developed methods for incorporating complexity in sustainability assessment frameworks. Further work is required in testing and validating these methodologies at multiple system scales and conditions. Integrating such tools in decision making mechanisms will enhance long-term management of socioecological systems performance.
