Linked Social-Ecological Systems: A Case Study of The Resilience of The Western Australian Agricultural Region

Helenallison@ozemail.com.au, Helen Elizabeth Allison January 2003 (has links)
In the Western Australian agricultural region, an area of approximately 14 million hectares (70,000 square miles), widespread areas of native vegetation have been cleared and replaced with annual cropping systems, predominantly wheat. Only1.3 million hectares (10%) of small and scattered native vegetation remnants remain. By 2000 16% of land in the region was at risk from soil salinity and was largely unproductive for commercial agriculture. A new hydrological equilibrium affecting 33% of the Western Australian agricultural region is predicted to be reached between 2050 and 2300. The starting premise of this dissertation is that normal disciplinary science was adopted as the dominant intellectual influence on natural resource management policy and thus natural resource degradation was treated as a problem for science, extracted from its social, economic and historical contexts. The second premise of this dissertation is that natural resource problems are not isolated scientific or technical problems, and are exacerbated by human failure to predict the complex inter-relationships among the social, ecological and economic systems. This dissertation initially provides an analytical narrative on the Western Australian agricultural region between 1889 and 2003 (114 years) with the main finding being that in the years pre-1970 a development-driven Western Australian Government was responsible for extensive land clearing for agriculture, often contrary to scientific advice. In the 1980s and 1990s the severity and extent of soil salinity and the prognosis of future negative trends in other natural resource indicators caused a rapid proliferation and evolution of Federal and State policies designed to ‘solve the problem’. Nonetheless many natural resource problems remain intractable. The second part of the dissertation investigates the epistemology of the normal science paradigm as it was applied to natural resource management problems in the 20th century as a potentially contributing cause. The evolution of an alternative epistemology, post-normal science paradigm, is then examined for explicating our current understanding of ‘reality’. A research framework was constructed which defines the post-normal science paradigm; the systemic approach; the bodies of theory–organisational, ecology, resilience and system dynamics theory; the social-ecological system perspective; and the methods–resilience analysis and system dynamics. This framework provides a novel way in which to gain a greater understanding of the fundamental or root causes of natural resource management problems. Using the case study of the Western Australian agricultural region a dynamic model was constructed based on descriptive information. An examination of the historical events and processes of the Western Australian agricultural region reveals that over a 114-year history it has evolved through two interactions of the adaptive cycle. Further investigation reveals these two cycles were synchronous with the second and third economic long-wave cycles or Kondratiev Cycles, that show the behaviour over time of the evolution of modern industrial societies. The model suggests that the reasons for the dynamic behaviour of the Western Australian agricultural region lie in the interaction of the three production growth drivers of the international commodity system, which have resulted in a pathological system, the ‘Lock-in Trap’. Increased total commodity production, reinvestment and declining prices in real terms have tended to produce the unintended negative impacts of resource decline, environmental pollution and rural population decline. I suggest that the expansion of thresholds through the reinvestment in technology is a principle reason why there has not yet been a profound collapse of exploited renewable resources in the Western Australian agricultural region. Regional natural resource management strategies will need to take account of not only spatial cross-scale issues, in particular the linkages between the individual farmer and the international commodity system, but also the temporal variables, in particular the slowly emerging changes in ecological/physical variables, such as the hydrological cycle. This research can help to provide the information and heuristic metaphors to encourage natural resource policy makers to take long-term and whole system perspectives. It includes a powerful set of tools for communicating dynamic processes in an integrated method to inform policy and management decisions. The ideas in this interdisciplinary research are essential for making science relevant within a social and ecological context.

The influence of COVID-19 on the trajectory of tourism businesses with respect to climate change mitigation : Case study: Northern Dalarna region, Sweden.

Pardos I Aybar, Daniel January 2021 (has links)
This research study is based on the way COVID-19 has affected the tourism businessesof the northern Dalarna region, Sweden. Moreover, how they responded to the crisis andif this response involved reconsidering their way of selling their touristic products. WithCOVID-19 effectively suspending the operations of the tourism sector such as air travel,the positive implications for climate change mitigation have been noted. This led toseveral speculations by researchers about the tourism industry taking this moment toreconsider their way of operating. However, these speculated decisions the tourismindustry will take amidst COVID-19 remain unproven. Therefore, this study aims todetermine how COVID-19 has affected the tourism companies of Northern Dalarna.Moreover, how these effects relate to conscious responses regarding climate changemitigation. Ultimately, this study intends to identify the relationship between the impactsof the present crisis COVID-19 and the future crisis that is climate change through thelens of the interviewed businesses in Northern Dalarna that effectively represent thetourism industry.Semi-structured interviews were employed as the main method for data collection. Seveninterviews of a diverse range of tourism businesses were conducted. The findingsacquired from the interviews show how these businesses have successfully overcome theeffects of COVID-19 while remaining open. The study concludes with very diverseperceptions of climate change from the companies. Moreover, how these perceptionshave evolved since the onset of COVID-19. Nevertheless, these companies had acommon point where independently of their opinion about climate change, all of themtook some actions to mitigate it. It was found that, for the case of Dalarna, Sweden,COVID-19 did not result in a moment for tourism companies to transform theirbusinesses to focus more on climate change mitigation. Business proceeded as usual interms of climate change mitigation and in the presence of COVID-19.There are several hypothetical studies on this topic, however, very few empirical studieswere found. This research contributes by showing how COVID-19 was not a time toconsider climate change mitigation according to the interviewed companies of NorthernDalarna, Sweden but merely a moment for minor adaptions.

Institutional Resilience of Community-based Conservation to the Maoist Insurgency in Nepal

Baral, Nabin 07 December 2009 (has links)
To explore the institutional resilience of community-based conservation, I undertook empirical research in the Annapurna Conservation Area (ACA), Nepal, a protected area managed by the Annapurna Conservation Area Project (ACAP) and local communities organized into 56 Conservation Area Management Committees (CAMCs). I conducted scripted interviews with 212 members of 30 representative CAMCs, 13 ACAP staff members who closely monitor those CAMCs, and 868 local villagers who are the beneficiaries of the conservation programs. The field research was undertaken during the summer of 2007 and fall of 2008. Both quantitative and qualitative data were collected and analyzed. I estimated capital stocks and assessed the organizational resilience of each CAMC during and following the Maoist insurgency. I used confirmatory factor analysis to develop scales for measuring the two theoretical constructs of legitimacy and institutional resilience, the latter of which refers to the overall system of community-based conservation in the area. I used the adaptive cycle framework of growth, maturation, collapse and reorganization to assess changes in structures and processes and to explore the past, present and possible future trends in ACA. Villagers largely considered the CAMCs as legitimate institutions, and their executive members as trustworthy. CAMC members understood the organizational mission and were confident about assuming greater management responsibility of the area in the near future. Human and social capital stocks were positively related to the resilience of the CAMCs. Particularly, themes of intra-committee trust, help networks, and the duration of members' tenure on the committees were important. Furthermore, natural capital stocks showed a parabolic relationship with organizational resilience; the most resilient CAMCs had moderate amounts of natural capital under their jurisdictions. The scales used to measure legitimacy and institutional resilience were reliable, and showed a significant positive correlation with each other. Five variables significantly predicted the villagers' perceptions of legitimacy: performance assessments of CAMCs, social norms as measured by perceptions of peers' attitudes towards CAMCs, empowerment as measured by villagers' perceptions of their influence in the CAMCs' decision making processes, perceived benefits and costs associated with having the CAMC in a village, and reported levels of personal participation in CAMCs' activities. The conservation institution appeared to have been resilient to the insurgency, as the system maintained its identity throughout, avoided alternative undesirable states, and entered into the reorganization phase following collapse. All forms of capital and institutional performance decreased to some extent during collapse but institutional memory, available capital and some structural changes facilitated reorganization. The institutional system is reorganizing along the original regime, but it has also developed an alternative pathway of a new governance model for the area that will transform the present regime in the near term. / Ph.

Social and environmental change as determinants of ecosystem health: A case study of social ecological systems in the Paterson Valley NSW Australia

Archer, Alan Cameron January 2007 (has links)
Research Doctorate - Doctor of Philosopy (PhD) / An environmental history approach is used in this thesis as a foundation for the analysis of the social and environmental changes that have occurred from the ancient past to the present within the Paterson Valley in New South Wales, Australia. The study examines the biophysical basis of the valley’s ecological processes and then describes the influence of the activities of Aboriginal peoples and subsequent European colonisation on the landscape. The study makes use of the various methodologies within social and ecological systems to assist with the analysis. It demonstrates the value of concepts such as complex adaptive systems, the adaptive cycle, panarchy and ecosystem health as ways of conceptualising complex transdisciplinary issues to reach conclusions based on temporal and spatial evidence. The complex relationships that the Aboriginal peoples had with the environment are compared with the various and rapid phases of colonial influences and processes. The social dimension of the changes over time is examined particularly with respect to the Indigenous and European institutions and infrastructure that influence the landscape. A significant issue identified in the study was the changing influence of Western institutions on the ecosystem health of the Valley; from local to global. The implications of this on ecosystem health are discussed. The Valley’s landscapes are divided into alluvial and non-alluvial, with the latter receiving the most attention in the study primarily due to its more extant nature whereas the alluvial rainforest has been virtually eliminated through extensive land clearing. The analysis of the non-alluvial landscape shows how important the Indigenous land management practices were in the maintenance of a complex mosaic of vegetation types specifically influenced by fire. The impact of the removal of the Indigenous influences on the landscape and the imposition of European practices and processes have seen a major reduction in the Valley’s ecological complexity. The study identified processes and factors external to the Valley which are increasingly influencing it. Not all of these are detrimental but they result in the Valley’s ecosystem health being more dependent on global events and processes. The study demonstrates the value of the ecosystem health framework for conceptualising the Valley’s ecosystems and the adaptive cycle for analysing and understanding their changes over time. These approaches provide an opportunity to identify pathways for future management of the Valley’s resources.

Of Chaos And Clockworks : A Formal Criticism Of The Modern Sustainability Paradigm

Arnström, Sebastian January 2023 (has links)
This thesis is a critical review of two central theories in the modern sustainability paradigm – namely… (1) the theory that the Earth’s geosphere, hydrosphere, biosphere and atmosphere form a complex adaptive system – the Earth system, and (2) the theory that all human activities are intrinsically dependent on, and constrained by, non-anthropogenic states and processes in the Earth system. The thesis explains the origins and the logic of these theories, and subjects them to formal, semi-formal and comparative criticism. Ultimately, it refutes both on formal and comparative grounds. Most importantly, it shows that theories 1 and 2 are in conflict with the theory of evolution by natural selection, and with the hypothetico-deductive model of scientific research. It also shows that they are in conflict – both directly and indirectly – with the known laws of physics. While it is true that all human activities rely on biospheric resources today, there are no physical, or natural laws that make it impossible for us to break those dependencies over time. In fact, the thesis shows that it is possible in principle to satisfy any human need by strictly artificial means, and abiotic resources that exist in abundance both inside and outside of the Earth system. An important corollary to this finding is that social and economic progress is not inextricably tied – as the modern sustainability literature suggests – to the exploitation of finite and rapidly diminishing resources here on Earth. Theories 1 and 2 both contribute to this confusion, and hence, to the bleak and irrational Malthusianism that still permeates so much of the sustainability domain. In addition, they appear to blind many researchers to the ecological benefits of technological development. That humanity can break its dependence on the biosphere is a very good thing for its non-human inhabitants. As we become more technologically advanced, we will find it easier and easier to sustain ourselves without destabilizing the world's ecosystems. The Earth’s biosphere is an oasis of beauty, complexity and connection in a Universe that is overwhelmingly empty and boring. As the only animals capable of appreciating this fact, we have a clear moral duty to protect and preserve it. And we can protect and preserve it. If we just let go of the religious ideas that have dominated our field since its inception, we will find that our potential to do good in the world is far greater than we previously imagined.
