Throughout history there has been a close relationship between hydrological and social processes. Most of early civilizations around the world developed thanks to the accessibility to rivers and their water resources. However, traditional hydrological approaches have not been able to capture this observed interaction and have ignored for too long the human-driven impacts in the hydrological system and how they, in turn, shape the hydrological conditions that have been commonly observed. The present research develops a new conceptual model with the intention to capture the two-way interactions between societies and their responses under extreme hydrological events, both floods and droughts. This conceptualization accounts for the observations that societies accumulate memory (increase the level of awareness) after an extreme events. Based on the accumulation of societal memory, the human system (societies) takes decisions about water management, thus impacting the hydrological system (rivers). When no extreme hydrological events are registered, societal memory decays at a certain rate and then new decisions are taken over the water management of the hydrological system. Inspired by the extreme droughts and floods events observed in the three last decades in the catchment of the Brisbane River in Australia, the aforementioned conceptualization is applied. Results indicated that the simple proposed conceptual model is able to capture the interactions between the human and the hydrological system. Additionally, the model exposes that societal memory is the driver of the human system and is the main reason for societies to create impacts on the natural conditions of the catchment. At the same time, this conceptualization demonstrated that water management decisions based on the accumulation of societal memory can actually create an exacerbation of the potential damages associated to extreme hydrological events. Finally, the development of this new approach points out the strong necessity to acquire further insights to improve the understanding of the interplay between hydrological and social processes. / Genom historien har det funnits en nära relation mellan hydrologiska och sociala processer. De flesta tidiga civilisationer runt om i världen utvecklades tack vare tillgången till floder och deras vattenresurser. Traditionella hydrologiska metoder har emellertid inte lyckats fånga denna observerade interaktion och har alltför länge ignorerat de mänskligt drivna effekterna i det hydrologiska systemet och hur de i sin tur formar de hydrologiska förhållandena som ofta observerats. Denna forskning har utvecklat en ny konceptuell modell med avsikt att fånga tvåvägsinteraktionen mellan samhällen och deras respons under extrema hydrologiska händelser, både översvämningar och torka. Denna konceptualisering baseras på observationen att samhällen ackumulerar minne (ökar medvetenheten) efter en extrem händelse. Baserat på ansamling av samhällets minne fattar det mänskliga systemet (samhällen) beslut över vattenhushållning, vilket påverkar det hydrologiska systemet (floder). När inga extrema hydrologiska händelser registreras, avklingar samhällsminnet med en viss hastighet och sedan fattas nya beslut om vattenhushållningen i det hydrologiska systemet. Den konceptuella modellen har tillämpats på Brisbaneflodens avrinningsområde, i Australien, med anledning av den extrema torka och stora översvämningar som observerats under de tre senaste decennierna. Resultaten tyder på att den enkla föreslagna konceptuella modellen kan fånga samspelet mellan människa och hydrologiska system. Dessutom visar den att ett samhälles minne är drivkraften för det mänskliga systemet och är den främsta orsaken till att samhällen gör inverkan på de naturliga förhållandena i avrinningsområdet. Samtidigt visar konceptualiseringen att denna typ av vattenförvaltning, som baseras på samhällsminnet, faktiskt kan förstärka de potentiella skador som kan uppkomma i samband med extrema hydrologiska händelser. Slutligen framhåller utvecklingen av denna nya metod det stora behov som finns för att förbättra förståelsen av samspelet mellan de hydrologiska och sociala processerna.

Environmental sociology and the sociology of scientific knowledge provide a strong theoretical foundation for investigating the role of science in environmental disputes. The field of environmental dispute resolution has built a body of literature, outlining the techniques and practices that underpin the successful resolution of disputes, over controversial environmental issues. However, the literature on dispute resolution has generally neglected the role of science in environmental disputes. This thesis develops a theoretical framework based on concepts from environmental sociology and the sociology of scientific knowledge in order to critically examine the role of science in environmental disputes. In particular, this thesis combines the theory on claims-making from environmental sociology with actor-network theory and the theory on boundary-work from the sociology of scientific knowledge, to analyse the way in which science was involved in the dispute over phasing out extractive dredging from the Brisbane River. Data were collected from qualitative in-depth interviews with key players in the Brisbane River dredging dispute and combined with analysis of relevant documents and newspaper articles. Each of the components of the theoretical framework developed in this thesis contributes to an in-depth analysis of the way in which science was involved in the dredging dispute. The environmental claims-making analysis examines the way in which the claim that extractive dredging was an environmental problem for the Brisbane River was constructed and contested. The actor-network analysis compares the two competing actor-networks that were developed by one of the major concrete companies and by the anti-dredging campaigners. The boundary-work analysis examines the social construction of the science / politics border as an important site of boundary-work, before exploring other related forms of boundary-work within the case study. When combined, these theories highlight the social and political processes that underpin the inherent difficulties associated with applying science to effective environmental dispute resolution. The theoretical framework developed in this thesis highlights the way in which an analysis of environmental claims-making, actor-networks and boundary-work, extends the literature on environmental dispute resolution. This thesis therefore makes a significant contribution to the field of environmental dispute resolution, by illustrating the advantages of drawing on theoretical perspectives from environmental sociology and the sociology of scientific knowledge.

Thesis (MA)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: A major concern for Energex, Australia's largest energy utility in South East Queensland, is the escape of natural gas out of their reticulation systems. Within many of the older areas in Brisbane, these networks operate primarily at low and medium pressure with a significant percentage of mains being cast iron or steel. Over many years pipes in these networks have been replaced, yet reports show that unaccounted for gas from the same networks remain high. Furthermore, operation and maintenance budgets for these networks are high with many of these pipes close to the end of their economic life. When operation and maintenance costs exceed the costs of replacement, the Energex gas utility initiates projects to renew reticulation networks with polyethylene pipes. Making decisions about pipe renewal requires an evaluation of historical records from a number of sources, namely: • gas consumption figures, • history of leaks, • maintenance and other related cost, and • the loss of revenue contributed by unaccounted for gas. Financial justification of capital expenditure has always been a requirement for renewal projects at the Energex gas utility, however the impact of a deregulation in the energy utility market has necessitated a review of their financial assessment for capital projects. The Energex gas utility has developed an application that evaluates the financial viability of renewal projects. This research will demonstrate the role of GIS integration with the Energex financial application. The results of this study showed that a GIS integrated renewal planning approach incorporates significant benefits including: • Efficient selection of a sub-network based on pipe connectivity, • Discovery of hidden relationships between spatially enabled alphanumeric data and environmental information that improves decision making, and • Enhanced testing of proposed renewal design options by scrutinizing the attributes of spatial data. / AFRIKAANSE OPSOMMING: 'n Groot bron van kommer vir Energex, Australië se grootste energieverskaffer in Suidoos- Queensland, is die verlies van natuurlike gas uit hul gasdistribusie netwerke. In 'n groot deel van ouer Brisbane opereer hierdie netwerke hoofsaaklik teen lae en medium druk, met 'n aansienlike persentasie van hoofpyplyne wat uit gietyster of staal bestaan. Al is sommige pyplyne in hierdie netwerke met verloop van tyd vervang, maak verslae dit duidelik dat 'n groot deel van die gas in hierdie netwerke steeds langs die pad verlore gaan. Die operasionele - en onderhoudsbegrotings vir hierdie netwerke is boonop hoog, met 'n groot persentasie van die pyplyne wat binnekort aan die einde van hulle ekonomiese leeftyd kom. Wanneer operasionele- en onderhoudsonkostes die koste van vervanging oorskry, beplan Energex se gasvoorsienings-afdeling projekte om verspreidingsnetwerke te hernu met poli-etileen pype. Om sinvolle besluite te neem tydens pyplynhernuwings, word verskeie historiese verslae geraadpleeg, insluitend: gasverbruikvlakke, lekplek geskiedenis rekords, onderhoud- en ander verwante onkostes, asook die verlies van inkomste weens verlore gas. Alhoewel finansiële stawing van kapitale uitgawes nog altyd 'n voorvereiste was tydens hernuwingsprojekte by Energex, het die impak van privatisering op die energieverskaffingsmark dit noodsaaklik gemaak om hulle finansiële goedkeuringsproses vir kapitaalprojekte te hersien. Energex het dus 'n sagteware toepassing ontwikkel wat die finansiële gangbaarheid van hernuwingsprojekte evalueer. Hierdie navorsing sal die moontlike integrasie van geografiese inligtingstelsels (GIS) met dié van Energex se finansiële evalueringspakket demonstreer. Die resultate van hierdie studie toon dat die integrasie van GIS in die hernuwingsproses aansienlike voordele inhou, insluitende: • die effektiewe seleksie van sub-netwerke, gebaseer op pyp konnektiwiteit, • die ontdekking van verskuilde verwantskappe tussen geografies-ruimtelike alfanumeriese data en omgewingsinligting, wat besluitneming vergemaklik, en • verbeterde toetsing van voorgestelde hernuwingsopsies deur die indiepte-nagaan van geografiesruimtelike elemente.

It is accepted protocol among Indigenous communities to identify one's link to land. I was born and raised in Brisbane. My birth grandmother is a Goreng Goreng woman, my birth grandfather is a Punthamara man. However, I was adopted by a Koombumberri man and an anglo-celtic mother after being removed at birth under the Queensland government policy of the day. The action of my removal and placement has had profound effects upon my growing and my place within my community today. For the last 15 years I have worked in the health sector. My current position is as a Lecturer within the Department of Nursing, Faculty of Science, University of Southern Queensland, Toowoomba. My areas of expertise are Indigenous Health and Primary Health Care. I have been employed in this capacity since January 2000. Prior to my full time employment as a nursing academic I have primarily been located within three areas of health which have directly impacted upon my current research. I was first positioned within health by undertaking my General Nurse Certificate through hospital-based training commenced in the late 1980s. For me this training meant being immersed within whiteness and specifically the white medical model. This meant learning a set of skills in a large institutionalised health care service with the provision of doctors, nurses, and allied medical staff through a hospital. Within this training there was no Indigenous health curriculum. The lectures provided on 'differing cultures' and health were on Muslim and Hindu beliefs about death. At that point I was painfully aware of the glaring omission of any representation of Indigenous health and of acknowledgment of the current outstanding health differentials between Indigenous and non-Indigenous Australians. I knew that the colonisation process inflicted upon Indigenous Australians was one of devastation. The decline in our health status at the time of colonisation had been felt immediately. Since this time our health has been in decline. While in the 1980s it was now no longer acceptable to shoot us, poison our waterholes, and incarcerate us on missions, we were still experiencing the influence of the colonisation process, which had strong repercussions for our current health status. Our communities were and remain rife with substance abuse, violence, unemployment, and much more. For Indigenous Australians these factors cannot be separated from our initial experience of the colonisation process but are seen as the continuation of it. However, there was no representation of this and I received my first health qualification.

There has been much interest in the last decade concerning the factors that influence diversity, especially how diversity and ecosystem processes may be linked. This study was based in small, cobble streams in South East Queensland. Its aim was to determine how the diversity and composition of consumers (the grazer guild) is influenced by both the production and composition of benthic algae, at different spatial scales. It also aimed to ascertain whether this response differs among grazer sub guilds with different dispersal capabilities. Ten sites in the Upper Brisbane and Mary catchments were sampled. The sites were selected to provide a range of productivity and composition. Grazers from these sites included snails and elmids, and larval mayflies, moths, and caddisflies. Grazer diversity and composition appeared to be structured by catchment scale influences, but environmental variables also affected which animals colonised patches and microhabitats (cobbles) within catchments. Primary productivity and algal composition could not be separated, with highly productive reaches also having a high cover of filamentous algal taxa. Grazer diversity displayed strongly positive, linear relationships with algal variables at the reach scale. It had a negative relationship with filamentous algae at the cobble scale, and a non-significant hump-shaped relationship with primary productivity. Survey data alone could not separate whether grazers were responding to habitat or food-related drivers, or to variations in productivity. Experimental manipulation of algal variables at the patch scale, using light and nutrients, also could not clearly uncouple the relationship between primary productivity and filamentous algal cover. Once reach scale variation was removed, grazer diversity displayed hump-shaped relationships with algal variables, including algal diversity. Much of this variation was due to patterns in mobile grazers, as sedentary grazers did not respond to algal variation at this scale. The density of the more mobile taxa showed similar patterns to those at the cobble scale (hump-shaped). A second field experiment was carried out in order to further investigate the responses of invertebrates to algal community composition at the cobble scale. Data from all three chapters suggested that as sites shifted to a dominance of filamentous algae, often with an associated increase in GPP, there was also a shift in the grazer community towards more sedentary grazers and away from the more mobile taxa. This also occurred at the cobble scale in the second experiment. The gut analysis and diet studies in the third chapter indicated that while many grazers consumed filamentous algae, it was not assimilated. This suggests that the preferences for sedentary taxa for cobbles and reaches dominated by filamentous algae are likely to be due to some other, possibly habitat-related, factor such as flow or predation refuge. The study provides a rare examination of relationships between primary productivity and consumer diversity in freshwater streams, and finds support for the pattern found in other systems of monotonic relationships of these two variables at large scales and hump-shaped relationships at smaller scales. It emphasises the importance of understanding other, potentially confounding, aspects of communities of producers, and investigates the possible roles of the most important of these (community composition) in structuring consumer communities in the small cobble streams of South-East Queensland.

Education for sustainability (EFS) is emerging as a key strategy for learning and action towards sustainability. Community-based environmental groups are potentially important providers of, and contexts for, educating adults for sustainability because they engage the community in activities such as public awareness raising, advocacy and lobbying, community education, and participatory learning (UNESCO, 2004, p. 25). These groups have been identified as key stakeholders of EFS in UNESCO's strategic plan for the United Nations Decade of Education for Sustainable Development, from 2005-2014 (UNESCO, 2004). Despite this recognition, there are few models or precedents to guide groups or programs in developing and implementing EFS in their strategies or activities. Additionally, education commonly associated with community-based environmental groups has been rather narrowly conceived as public awareness raising and individual behaviour change, and disconnected from advocacy (Clover, 2002a; Whelan, pending). This thesis addressed this gap in understanding by investigating the dimensions of education and learning in two community-based environmental groups in South-East QueensIand. The aim of this research was to develop a framework to explain and understand the role of education and learning within and by community-based environmental groups. The research inquiry was motivated by an interpretive interest in uncovering the educative dimensions arising from group members' engagement in the activities of community-based environmental groups. This aim was addressed through an investigation of: (1) the community education initiatives of community-based environmental groups; and (2) the learning that occurs within these groups through participation in social action, Two community-based environmental groups that participated in this study were Smogbusters, an environmental advocacy group, which focused on air quality and transport issues in Brisbane; and the Pumicestone Region Catchment Coordination Association, (PRCCA) a community-based natural resource management group. Information was gathered through participant observation, interviews with group members and project staff, and the collection of relevant documents from both groups. A conceptual framework based on five convergent themes in the contemporary EFS literature was used to interpret and analyse the activities of these groups, These are: (1) participation; (2) critical thinking; (3) local relevance; (4) holistic, interdisciplinary and systemic approaches; and (5) values-driven approaches. The analysis of both groups' community education initiatives revealed the use of approaches that extend beyond pubhc awareness, didactic, and information-based approaches to strategies that engaged the community more actively than was possible with conventional approaches. This reflects a more sophisticated and considered approach that connects education with advocacy as an integral part of groups' strategy and practice. The two case studies illustrate the use of participatory learning and action that incorporates adult learning approaches to enhance participation and learning. These findings contribute to knowledge that can help bridge the gap between education and advocacy in the activities of community-based environmental groups (Clover, 2002a; Whelan, 2005). The findings strongly suggest that the two groups engaged a form of education and action that approaches the potential of EFS as envisaged in policy documents and vision statements. The groups provided opportunities for action learning through advocacy and lobbying for policy change, and through a range of activities associated with addressing issues of natural resource management. In Smogbusters, participation in advocacy and education contributed to building the capacity of individuals to engage in social action for sustainable transport and air quality. In the PRCCA, group members' participation in natural resource management related activities developed their skills, knowledge and capacity to advocate for sustainable natural resource management practices. These findings confirm that local participation in environmental action and decision making builds on the individual and collective experiences of participants. Participation in action empowered and enabled group members to engage in action and change. In particular, participants developed a strong sense of their capacity to enact change, and to engage in social action. The findings of this research suggest that community-based environmental groups are important places for adults to gain a stronger sense of personal and collective agency towards sustainability. Further, participation in these groups is an important mechanism for environmental change to be brought about through collective action (Apel & Camozzi, 1996). The research findings confirm that adult and popular education pedagogies can optimise learning in community-based environmental groups (Foley, 1999; Clover & Hall, 2000; Clover; 2002a; Follen & HaIl, 1998; Newman, 1995a). The framework may be able to assist project coordinators in developing and implementing community education strategies into their programs. Finally, the findings have implications for policy and program development in the Decade of Education for Sustainable Development.

The late 1980s saw the onset of a rapid expansion of Chinese immigration into Australia. While this influx of Chinese migrants has produced a proliferation of research on the more affluent migrants from Hong Kong and Taiwan, studies on migrants especially women from the People's Republic of China (PRC) have remained few and far between. Among those few studies on PRC-born migrant women, all of them identified settlement stress and its health implications as a major concern among PRC-born migrant, yet there has been little concerted effort on why this is the case, particularly in the area of health needs and solutions. Considering the increasing presence of PRC-born migrant women in Australia, there is a clear need for a comprehensive in-depth investigation into their settlement stress, to address their social and health needs and to provide solutions. This study aims to examine in-depth the PRC-born migrant women's settlement experience in Brisbane, focusing especially on their stress, social and health needs. This study employed both qualitative and quantitative methods. Since this study paid more attention to these migrant women's own life experiences, it is mainly a qualitative one, using informant interview, focus group and in-depth interviews to explore how best their stress could be alleviated. Quantitative method is based on secondary data analysis to provide a community profile of PRC-born migrant women in Brisbane and Queensland. This study firstly draws on literature reviews to explain historical, social, cultural and gender based factors underpinning PRC-born migrant women's settlement stress and health status. Findings reviews that settlement stress comes from social isolation and loneliness; cultural difficulties; lack of support prior to and after childbirth, as well as assistance with childcare; conflicts in both marital and familial relations; academic stress; and finally, problems in utilising public transport. Particularly, this study highlights that downward mobility; barriers to access health services; and language barriers are a major source of stress and the cause of health problems for PRC-born migrant women when settling in Brisbane. As strategies, this study adapts health promotion strategies named as empowerment framework and Ottawa Charter action framework to address the needs highlighted in this study. Settlement stress affects health particularly mental health. Strategies provided in this study can also help migrant women from other non-English speaking countries. More significantly, this study encourages governments and service providers to pay more attention to migrant women's settlement processes in order to help them integrate into Australian society smoothly and quickly.

There is a recognised need for the continued improvement of both the techniques and technology for spatial decision support in infrastructure site selection. Many authors have noted that current methodologies are inadequate for real-world site selection decisions carried out by heterogeneous groups of decision-makers under uncertainty. Nevertheless despite numerous limitations inherent in current spatial problem solving methods, spatial decision support systems have been proven to increase decision-maker effectiveness when used. However, due to the real or perceived difficulty of using these systems few applications are actually in use to support decision-makers in siting decisions. The most common difficulties encountered involve standardising criterion ratings, and communicating results. This research has focused on the use of Approximate Reasoning to improve the techniques and technology of spatial decision support, and make them easier to use and understand. The algorithm developed in this research (ARAISS) is based on the use of natural language to describe problem variables such as suitability, certainty, risk and consensus. The algorithm uses a method based on type II fuzzy sets to represent problem variables. ARAISS was subsequently incorporated into a new Spatial Decision Support System (InfraPlanner) and validated by use in a real-world site selection problem at Australia's Brisbane Airport. Results indicate that Approximate Reasoning is a promising method for spatial infrastructure planning decisions. Natural language inputs and outputs, combined with an easily understandable multiple decision-maker framework created an environment conducive to information sharing and consensus building among parties. Future research should focus on the use of Genetic Algorithms and other Artificial Intelligence techniques to broaden the scope of existing work.
