Political culture, governance and climate change adaptation : case study of South Korea

Park, Keumjoo January 2013 (has links)
Many scholars highlight the essence of a participatory governance approach to climate change adaptation and the positive impact of allowing multiple actors participation in the process of decision making as a determinant for successful adaptation to climate change. However, political culture in some societies does not support participation, and people are neither interested nor even aware of political actions. There are very few studies carried out that examine cultural, especially political cultural, influences over governing climate change adaptation. In response to this academic gap, this research aims to investigate how political culture influences a governance approach to climate change adaptation. Using an empirical case study of the process of formulating national climate change adaptation policies in South Korea, this study examines the way decisions are made about climate change policies under ‘dominant bureaucratic’, ‘authoritarian’ and ‘weak participant’ political cultures and investigates how such political cultures will hamper or encourage a governance approach to effective climate change adaptation. This study therefore advances knowledge about how political culture influences climate change adaptation. It provides a basis for comparative analyses of other political cultures in different regions and will enable scholars to understand the challenges that particular forms of governance hold for promoting climate change adaptation.

The Role of Local Knowledge in Sustaining Ecotourism Livelihood as an Adaptation to Climate Change

Agyeman, Yaw Boakye 14 December 2013 (has links)
Ecotourism is a development strategy for many local communities in and around protected areas. Its ability to improve tourism opportunities, conservation and livelihoods is supported by many ecotourism studies. Such communities often employ diverse livelihood strategies to reduce risk and survive. As such, ecotourism becomes an integral part of a portfolio of livelihoods and assist with livelihood diversification. However, in some locales climate change is making livelihoods, including ecotourism vulnerable, due to its impacts on protected areas and their associated biodiversity. Climate change creates vulnerability as well as opportunities for adaptation. Climate change adaptation has become important in ensuring tourism sustainability, as it is critical in reducing the vulnerability of tourism. However, the literature supplies only limited knowledge on such adaptation at the local level. This may undermine ecotourism???s prospects in improving local livelihoods and conservation. There is a need to understand the lived and embodied everyday experiences of local communities who are experiencing tourism within the context of climate change. In particular, this research needs to capture local knowledge and understanding of climate change, and local efforts at adaptation. In understanding adaptation at the local level, it is important to understand how households construct their livelihoods, including the role of ecotourism. This study examined local perceptions and lived experience in sustainable ecotourism development as a livelihood adaptation to climate change in a case study site in Ghana. This examination and subsequent understanding provided a process for integrating local knowledge into livelihood adaptation as communities become more vulnerable to future climate change that will adversely affect traditional patterns of livelihoods. The study used the vulnerability-based approach which assessed vulnerability of households??? livelihoods to climate change and adaptations. Mognori Eco-Village in Ghana was used a case because of its geographic location in the savannah and experience of climate change as well as households` involvement in ecotourism activities. In focusing on lived experience, the study was guided by the philosophical ideas of Gadamer, as it lends itself particularly well for exploring the complexities and understanding of households??? lived experience with climate change. It also informed the recruitment of 22 households, use of conversation interviews and a focus group as well as data interpretation. The study found four main underlying essences that explain households??? lived experience with climate change: 1) adopting different livelihood strategies; 2) experiencing the impacts of ecotourism on assets and activities; 3) experiencing current vulnerability conditions and developing adaptation strategies; and, 4) sustaining ecotourism by building future adaptation strategies. The first essence suggests strategies such as intensification/extensification, livelihood diversification and migration as broad adaptations for survival. The second essence supports the use of ecotourism as a form of livelihood diversification that complements other non-ecotourism activities. The third essence describes the vulnerability to climate change the local adaptations use to reduce vulnerability. The last essence suggests local agency in overcoming adaptation constraints to improve adaptive capacity to sustain ecotourism as an adaptation strategy to climate change. The study found that local adaptive capacity exists to support ecotourism. However, the capability of the local community is limited and recommendations are made for government and other stakeholders to further support the local adaptation that is underway.

Management Planning for Combined Sewer Systems in Urban Areas under Climate Change

Renaud, Thomas 30 April 2012 (has links)
Management of urban stormwater is becoming increasingly difficult due to an anticipated increase in precipitation and extreme storm events that are expected under climate change. The goal of this research is to develop an approach that effectively accounts for the uncertain conditions that may occur under climate change and to develop best management practices to manage stormwater in urban areas. This presentation focuses on management of stormwater and combined sewage in Worcester, MA, where approximately four square miles of the downtown area is serviced by a combined sewer system. The EPA Stormwater Management Model was used to determine the impacts of storms on the urban environment for future conditions. This model was used to simulate discharges of selected design storms associated with a range of climate change scenarios. Various design storms were simulated in SWMM for 2010, 2040, and 2070 under high, moderate, and low climate change scenarios. Alternative best management practices were assessed in terms of specific metrics that included flood volumes and combined sewer overflow volumes through the Worcester sewer system. Cost evaluations were used to identify appropriate best management strategies for managing the combined sewer system under future scenarios. A design cost approach and net benefits approach were used to analyze different options for managing stormwater under climate change. Both of these approaches utilize the concept of risk analyze to determine expected values of both costs and benefits for different options under different climate change scenarios. Results for the design cost approach indicate that providing upstream underground storage in select locations throughout the Worcester combined sewer system is the most cost-effective strategy. In addition, increased pumping capacity at the Quinsigamond Avenue Combined Sewer Overflow Storage and Treatment Facility (QCSOSTF) should be included for this option. However, it was determined that only select upstream storage is the most beneficial option under the net benefits approach as increased pumping capacity at the QCSOSTF was determined to be too costly due to the additional costs of CSO treatment required at the facility. The Worcester case study provides an ideal context for assessing the relative advantages of full treatment at the wastewater treatment facility, limited treatment at a centralized CSO treatment facility, decentralized storage options, and low impact stormwater controls. It also allows for an assessment of decision making methods for controlling flows and loads from the Worcester system. Comparisons between Worcester and other case studies provide a foundation for understanding how stormwater and combined sewer systems can be managed given climate change uncertainty.

The climate change adaptation potential of integrating urban agriculture with architecture in inland South African cities

Hugo, Jan Marais January 2020 (has links)
In response to the protracted and ineffective international action on the climate change crisis, this study critically considers the potential of building-integrated agriculture (BIA) as retrofitting strategy to improve the climate change adaptation (CCA) capacity of buildings in South African inland cities. Based on a pragmatism paradigm, the study uses a mixed method research design, to evaluate current BIA farms and their efficacy as CCA retrofitting strategies to improve the thermal performance of the local built environment. The exploratory research is structured in three phases. During the first phase the unused and underutilised spaces of Hatfield, a rapidly changing neighbourhood in Tshwane, South Africa, are mapped and defined in terms of their latent climate change adaptation capability. Secondly, the spatial and technological characteristics of the current BIA industry is surveyed through a series of interviews and observational studies. As the final research phase, a specific BIA farm type, passively controlled non-integrated rooftop greenhouses, is assessed in terms of its reciprocal thermal impact on the built environment. As outcome, the research findings reveal a land-use form that can contribute to the climate change adaptation response strategies of South African cities on a spatial level. Unfortunately, the design resolution and technological realisation, specifically the prevalent form currently implemented in Johannesburg and Tshwane, adversely affect both farmers and building occupants during overheated periods. As a result, the study advocates developing and testing contextually appropriate technological solutions in the BIA industry. The study advances the climate change discourse by assessing the performance of BIA farms as constituent entities in networks of small-scaled climate change adaptation projects in resource constrained urban environments. / Thesis (PhD)--University of Pretoria, 2020. / Architecture / PhD / Unrestricted

Climate Change Relocation as an Adaptation Strategy: from Taboo to Opportunity

Bukvic, Anamaria 04 September 2012 (has links)
Relocation is often taboo among policy makers and planners due to its political, social, and ethical connotations, and although increasingly mentioned as one of the potential climate change adaptation strategies, it mostly adheres to rhetoric with limited discussion of its actual implementation. Scientific study and observation indicate the imminence of climate change impacts, many of which may exceed the adaptive capacity of vulnerability hotspots. Therefore, it is imperative to reassess this response option in the light of its past negative reputation, the success of current initiatives, and decision makers' evolving perception of relocation as an adaptation option. The main objective of this dissertation research is to determine the need for, interest in, and prospects for community relocations as an adaptation option; explore ways to address limitations associated with this alternative, and identify opportunities that could emerge from the relocation process. This study reviews experiences from the past and current relocation efforts and gauges the current level of interest in and support for this adaptation option among policy makers and planners. It also provides conceptual models - the relocation scenario, its digitalized simulation, the Climate Change Relocation Leaf, and the Relocation Suitability Index - designed to help communities, policy makers and planners explore this alternative. The research commences with a comprehensive literature review of theoretical knowledge, past experiences, current case studies, and the existing state of institutional, political, and social perspectives related to climate change migration and relocation. It continues with a comparative content analysis of climate change adaptation plans to elucidate the relocation rhetoric utilized in the selected texts at what frequency and in what context. Next, the study represents the climate change relocation models and a scenario developed to engage decision-makers and stakeholders in assessing the need for and possibility of relocation. Lastly, the project concludes with the development of a conceptual and tabular framework for the Relocation Suitability Index and subsequent simulation designed to compare possible relocation host sites systematically based on their absorption capacity. / Ph.

Coping with climate change uncertainty for adaptation planning for local water management

Green, Michael January 2014 (has links)
Environmental management is plagued with uncertainty, despite this, little attention has until recently been given to the sensitivity of management decisions to uncertain environmental projections. Assuming that the future climate is stationary is no longer considered valid, nor is using a single or small number of potentially incorrect projections to inform decisions. Instead, it is recommended that decision makers make use of increasingly available probabilistic projections of future climate change, such as those from perturbed physics ensembles like United Kingdom Climate Projections 2009 (UKCP09), to gauge the severity and extent of future impacts and ultimately prepare more robust solutions. Two case studies focussing on contrasting aspects of local water management; namely irrigation demand and urban drainage management, were used to evaluate current approaches and develop recommendations and improved methods of using probabilistic projections to support decision making for climate change adaptation. A quantitative understanding of the impact of uncertainty to decision making for climate change adaptation was obtained from a literature review; followed by a comparison of using (1) the low medium and high emission scenarios, (2) 10,000 sample ensemble and 11 Spatially Coherent Projections (11SCP), (3) deterministic and probabilistic climate change projections, (4) the complete probabilistic dataset and sub-samples of it using different sampling techniques, (5) the change factor (or delta change) and stochastic (or UKCP09 weather generator) downscaling techniques and (6) different decision criteria using two contrasting case studies at three UK sites. This research provides an insight into the impact of different sources of uncertainty to real-world adaptation and explores whether having access to more data and a greater appreciation of uncertainty alters the way we make decisions. The impact of the “envelope of uncertainty” to decision making is explored in order to identify those factors and decisions that have the greatest impact on what we perceive to be the “best” solution. An improved novel decision criterion for use with probabilistic projections for adaptation planning is presented and tested using simplified real-world case studies to establish whether it provides a more attractive tool for decision makers compared to the current decision criteria which have been advocated for adaptation planning. This criterion explicitly incorporates the unique risk appetite of the individual into the decision making process, acknowledging that this source of uncertainty and not necessarily the climate change projections, had the greatest impact on the decisions considered by this research. This research found the differences between emission scenarios, projection datasets, sub-sampling approaches and downscaling techniques, each contributing a different source of uncertainty, tended to be small except where the decision maker already exhibited an extremely risk seeking or risk adverse appetite. This research raises a number of interesting questions about the “decision significance” of uncertainty through the systematic analysis of several different sources of uncertainty on two contrasting local water management case studies. Through this research, decision makers are encouraged to take a more active role in the climate change adaptation debate, undertaking their own analysis with the support of the scientific community in order to highlight those uncertainties that have significant implications for real world decisions and thereby help direct future efforts to characterise and reduce them. The findings of this research are of interest to planners, engineers, stakeholders and adaptation planning generally.

The mountain pine beetle, climate change, and scientists : understanding science's responses to rapid ecological change in Western Canada

Lettrari, Heike 01 June 2017 (has links)
Today, climate change and rapid ecological change are impacting our ecosystems and landscapes in numerous, often surprising ways. These changes result in social, cultural, ecological, and economic shifts, as exemplified in the climate-exacerbated mountain pine beetle (MPB) outbreak in British Columbia. Recently, scientific communities have boosted calls for “usable science.” By interviewing leading MPB scientists, I ask, “How are scientists and their institutions responding to rapid ecological change?” Numerous factors shape MPB science—institutional support, funding, and values—and these factors enable and constrain effective relationships and ultimately, useful science, in response to the outbreak. Results suggest that while science and scientific institutions change slowly, and while relationships between MPB science and policy are characterized as tenuous, there are signs that crossing institutional boundaries (such as the TRIA Network) contributes to producing science that is more effective for responding to rapid ecological change. / Graduate

Climate change and conservation policy : developing adaptation strategies to minimise climate change impacts to the conservation interest of Scotland's standing freshwaters

Muir, Martin C. A. January 2016 (has links)
There is little doubt that anthropogenic climate change will have long lasting, unavoidable, large scale and cross sector effects. Having a clear understanding of the scale and rate of projected future changes, and the potential impacts of those changes at multiple spatial and temporal scales, will be important to allow environmental managers the best chance of adapting to changing conditions. There are particular concerns about impacts on freshwater systems due to the coupling of direct impacts to both hydrology and ecology. Expected changes can be grouped into three functional categories: those affecting physico-chemical (broadly water quality), hydromorphological (physical structure and habitat) and biological elements of the lake system. The Lake-Landscape Context framework provides a way of approaching the sensitivity or resilience of an individual lake to change by exploring the complex and multi-layered relations between water, land and human activity. However, the exact combination of strategies and actions available to environmental managers is yet to be comprehensively documented beyond broad principles. To reach this goal, to manage our ecosystems in the most comprehensive and responsible way, we need to have a clear understanding of what and where that resource is, what the conservation priorities currently are and where threats to these priorities are likely to emerge. Therefore, the overall aim of this thesis was to develop adaptation strategies to minimise climate change impacts on the conservation interests of Scotland’s standing freshwater. This was approached through the adoption of the ESVRA conceptual framework, intended to assist policymakers and practitioners in adaptation planning. Practical actions can be guided by working through the framework’s four key stages: understanding exposure to the pressure (external drivers); considering the sensitivity and resilience of the system at multiple scales (internal functions); exploring areas of vulnerability (a measure of sensitivity plus exposure); and consideration of multiple possible responses across spatial and temporal scales. Chapter 2 explores the lake resource making use of the latest geospatial data and GIS techniques to investigate Scottish standing freshwaters in depth. 5,165 Scottish lakes exhibit an outstanding myriad of forms and sizes ranging across the country. This variety of form, density and distribution contribute to habitats of international importance for numerous species. Perhaps because of this diversity, no natural grouping of lakes were found based on simple hydromorphological categorisations. The use of landscape and wildness ‘scoring’ is a novel geographic approach, which may be an important factor in how landscapes are valued in the future. Chapter 3 investigates the direct exposure to global climate change facing Scotland. Projected changes to global climate were downscaled to illustrate impact on the UK and Scotland using both the UKCP09 and HadGEM2-ES climate models. Climate change by the 2050s will impact the UK in the range 1.1°C to 2.7°C with a clear South-East/North-West gradient. Precipitation too is projected to change in the UK in this time, with annual precipitation varying from -65 to +116 mm/yr. By incorporating the climate model data into a GIS it was possible to further interrogate the results for specific locations, with a detailed water balance model created for all 5165 lakes. This model suggests that during the summer months there will be sustained periods of water scarcity and deficit. Finally, in this chapter, a climate change spatial risk assessment was undertaken, identifying 200 lakes in the area of greatest projected change. Leading on from these findings, Chapter 4 explores the vulnerability of Scotland’s standing freshwaters. A vulnerability framework attempts to place resilience as a key part of the model, which has to date been missing from similar assessments. The expert weighted scoring mechanism highlights 851 of Scotland’s standing freshwaters, geographically spread across the country, as being highly vulnerable to projected climate changes. The results were mapped to show the vulnerability across Scotland and a display system for individual lakes proposed that allows a transparent and coherent structure that can shed light on distinct components of vulnerability, so that each can be evaluated individually, and in combination. Finally, in Chapter 5, a multipart online survey with key stakeholder experts actively involved in freshwater environmental management was produced to approach adaptation strategies and actions themselves. Over 80 adaptation actions specifically applicable to Scotland’s standing freshwaters were collated and grouped into 12 adaptation strategies. All 12 strategies were considered desirable with six strategies considered ‘Definitely feasible’, a further four considered ‘Likely feasible’. This provides a framework of potential actions that could help to reduce system sensitivity by increasing adaptive capacity or system resilience. In conclusion, while there are undoubtedly challenges ahead for Scotland’s standing freshwaters and for those who manage them, there is clear opportunity to make proactive and engaged decisions to minimise the impact of climate changes on the conservation interest of these important habitats.

Ecosystem-based adaptation – In Theory and Practice : A case study of projects supported by the International Climate Initiative

Mellmann, Niels January 2015 (has links)
Ecosystem-based adaptation as a concept of adapting to the adverse effects of climate change has become a popular approach that enjoys a good reputation. However, the evidence base for it is rather thin. This thesis sets out to explore the challenges and limitations linked to projects that engage in the concept, in order to estimate the potential threat that may lie in the ignorance of them. Timescales of projects related to the concept shall be the second major focus of this thesis as it has not been sufficiently examined yet by the literature. Empirical material has been gathered and analyzed in the form of interviews with people who have been and are currently working in projects related to ecosystem-based adaptation. The results allow recommendations for the implementation of future projects, as lessons learned were identified.

Tacit knowledge transfer: planners learning from one another about climate change adaptation

Horton, Krysti 19 April 2013 (has links)
This practicum examines how planners can exchange tacit knowledge about climate change adaptation, in order to create better communities and to further the profession. Two regions of British Columbia - the Lower Mainland and the Kootenay’s - provided case studies to determine if and how tacit knowledge was exchanged. These two regions are provincial leaders in climate change adaptation, yet their constituent communities are at different stages of adaptation. Through a literature review and case study analysis - featuring key informant interviews, the practicum demonstrates that tacit knowledge is indeed being exchanged within the regions, yet not as strongly between them. Recommendations are offered aiming to improve tacit knowledge exchange within the profession of planning – among planners and through their professional planning Institutes, and for such exchange to be better supported by planning education.
