Organizational Adaptation and Resilience to Extreme Weather Events

Martina Linnenluecke Unknown Date (has links)
Impacts from climate change already pose major challenges for organizations and industrial systems, and vulnerabilities are expected to increase in the future, particularly in vulnerable sectors and locations. Findings by the Intergovernmental Panel on Climate Change (IPCC) suggest that climate change related vulnerabilities of organizations and industries, but also of settlement and society as a whole, are mainly related to changes in the intensity and/or frequency of extreme weather, rather than to gradual climate change impacts. Organization researchers and managers, however, have not yet systematically considered the organizational implications of changes in trends of weather extremes, such as changes to the intensity and/or frequency of storms, floods, and droughts. While companies in the reinsurance industry (e.g., Munich Re, Swiss Re) have begun to undertake research into changes in trends of extremes, most current debates on climate change and corporate response are mainly focused on adaptation – that is, longer-term adjustments that organizations can take in response to policy and legislative changes and the observed gradual warming trend. The question of how organizations can cope with more frequent and/or intense weather extremes has largely remained outside of these debates. The thesis advances the notion that the resilience concept which originated in disciplines such as ecology and engineering may provide insights into dealing with new types of environmental change arising from changes in patterns of weather extremes. It emphasizes that organizational adaptation and resilience potentials are context-specific and related to the characteristics of particular climate change impacts. While organizations may be able to undergo steady adaptations to gradual climate change (such as gradual increases in mean temperatures), they might not be able to handle disruptions that go beyond this gradual trend and are related to changes in extremes. Included in this thesis are five papers that seek to provide a foundation for understanding, assessing and evaluating organizational responses to more frequent and/or intense weather extremes. The first paper serves as an introduction to the thesis, assesses the literatures on organizational adaptation and resilience, and proposes an initial model that draws together the different streams of literature on climate change, adaptation and resilience. The second paper extends on the themes of the first paper and provides a discussion of the concepts of adaptation and resilience, as well as their applicability to different types of climate change impacts. The third paper serves as a method paper and discusses assessment methods and pathway to study organizational resilience. The key difficulties identified in this paper are the uncertainties about future climate change outcomes across temporal and spatial scales and a lack of insight into what leads to organizational resilience, or which variables should be measured in a given study. The fourth paper is an empirical study about the 2009 Victorian Bushfires. While individual extreme events cannot be directly linked to climate change impacts, this study highlights that part of the problem in drawing out the resilience of organizations to an unprecedented and ‘more-severe-than-expected’ extreme event is that a range of contingent variables across organizational and societal and ecological levels are potentially relevant. The last paper discusses the potential inability of organization to adjust to changes in climate and weather, and implications in terms of a necessity of a geographical shift of organizational and industrial activities. The thesis highlights gaps in our understanding of organizational challenges and suggests avenues for future research.

Putting the spin on wind energy: risk management issues associated with wind energy project development in Australia

Finlay-Jones, Richard Unknown Date (has links)
The debate on global warming is over (Stix, 2006 p24). The global community must now find ways to reduce greenhouse emissions, particularly from energy generation. Wind energy provides one of the potential solutions to generate renewable energy without creating harmful greenhouse gases. Wind energy is the fastest growing energy generation industry globally (‘Operating wind power capacity' 2006a). This rapid growth is being driven by increasing global energy demand, commitment from governments globally to international agreements including the Kyoto Protocol (UNFCCC 1997) to reduce the emission of greenhouse gases, as well as individual country commitments to mandatory renewable energy targets. Australia, whilst being a signatory to the United Nations Framework Convention on Climate Change (UNFCCC) commitment to reduce greenhouse gas emissions, has so far failed to ratify the Kyoto Protocol. In Australia, wind energy development to date has been driven primarily by the development of the Mandatory Renewable Energy Target (MRET) under the Renewable Energy (Electricity) Act 2000. This requires a commitment to 2% of total electricity generation (9,500GW) to be derived from renewable energy sources by the year 2010 (Warwryk, undated). It is now understood, that the current federal obligation to renewable energy is now oversubscribed, and consequently the likelihood of further wind energy projects being developed is highly limited (Brazzale 2005). External to the government commitment to renewable energy, the development of wind energy projects requires a range of inputs including, but not limited to; an understanding of the wind resource, security of land, access to suitable electricity transmission grid, a market for the electricity, access to suitable technology and a level of community support. Whilst the literature related to project management and risk management is extensive, the literature related to the risks associated with wind energy development in Australia is limited. This research then seeks to fill a void that asks the question; How can project managers minimise the risk associated with wind energy developments in Australia? To investigate this research problem, comparative case study analysis was adopted as a methodology utilising a structured interview process of project managers responsible for the development of 8 Australian wind energy projects. This research shows that the greatest risk to Australian projects is the lack of security associated with the current federal legislation and the consequent loss of market value of the power from wind energy projects. A number of additional primary and secondary risks are identified by the interview participants, and the research is able to draw out three common themes of risk management strategies. These three themes were categorised as conservatism, due diligence and proactivism. This study contributes to the research associated with project management, risk management and wind energy development. This insight into the Australian wind energy industry provides policy makers, educators and stakeholders with information to assist in improving the political, economic and social environment for further wind energy development, in order to mitigate against further greenhouse gas emission and combat global warming.
