Attitudes towards Ecosystem Services in Urban Riparian Parks

January 2012 (has links)
abstract: Urban sustainability is a critical component of sustainable human societies. Urban riparian parks are used here as a case study seeking to understand the social-ecological relationships between the subjective evaluation of ecosystem services and the vision and management of one kind of green infrastructure. This study explored attitudes towards ecosystem services, asking whether 1) the tripartite model is an effective framing to measure attitudes towards ecosystem services; 2) what the attitudes towards ecosystem services are and whether they differ between two types of park space; and 3) what the relationship is between management and the attitudinal assessment of ecosystem services by park users. A questionnaire was administered to 104 urban riparian park users in Phoenix, AZ evaluating their attitudes towards refugia, aesthetics, microclimate and stormwater regulation, and recreational and educational opportunities. The operationalization of the tripartite model was validated and found reliable, but may not be the whole story in determining attitudes towards ecosystem services. All components of attitude were positive, but attitudes were stronger in a habitat rehabilitation area with densely planted native species and low flows, than in a more classic park with mowed lawns and scattered vegetation, a mix of native and non-native species, and open water. Park users were more positive towards refugia, stormwater regulation, recreation, and educational opportunities in the habitat rehabilitation area. On the other hand, microclimate regulation and aesthetic qualities were valued similarly between the two parks. Most attitudes supported management goals, however park users valued stormwater regulation less than managers. Qualitative answers suggest that the quality of human interactions differ between the parks and park users consider both elements of society and the physical environment in their subjective evaluations. These findings reveal that park users highly value ecosystem services and that park design and management mediates social-ecological relationships, which should at least underlie the context of economic discussions of service value. This study supports the provision of ecosystem services through green infrastructure and suggests that an integration of park designs throughout urban areas could provide both necessary services as well as expand the platform for social-ecological interactions. / Dissertation/Thesis / M.S.

A Fashion System Without Getting Dressed? A Two-Strand Approach Towards Understanding How to Define and Transform a Global Complex Social-Ecological System

Palm, Celinda January 2017 (has links)
In this thesis, I view the global Fashion System in terms of hybridity, with the intention of developing a theoretical understanding of a sustainable fashion system. I explore a perpetuated micro-scale activity – getting dressed each day – as a driver of the fashion system. Thereby aiming to help in redefining and clarifying the dynamics of fashion as a complex social-ecological system, to inform of risks and opportunities towards sustainable fashion. This project has two strands; Firstly, a theoretical understanding of fashion as a social-ecological system emphasizing social and abstract representations. Secondly, an action-oriented research approach for understanding how the frameworks applied in a science-business collaborative project relate to sustainable fashion and how that affects their work. For this, I draw on Critical Realism as meta-theory, where the real world consists of both material and non-material stratified layers.  Dividing the fashion system in four stratified layers; physical, material interaction, socio-economic and culture, allows the bridging of theory and practice. I argue that three concepts hybridity, modernity and fashion are essential for visioning a future sustainable fashion system and that key social-ecological resilience theories are limited for weaving them together. I found that transformations towards sustainable fashion cannot be reduced to merely socio-technical solutions, as individual’s everyday perpetuated activity of getting dressed is linked to global negative environmental impacts. In the science-business collaborative project, key challenges were identified: inadequate amount of time, and absence of knowledge regarding the fashion industry and fashion theory as well as absence of critical reflections. Finally, I found that the concepts of affordances provide a useful link between human, ‘things’ and the abstract entities created through the value chains of the fashion system. Thus, I propose that affordances could be developed as a tool linking sustainability science, design studies and economic business models, enhancing knowledge in science-business collaborations.

“We monitor by living here”: actualization of a social-ecological monitoring program grounded in Gitga’at harvesters’ observations and knowledge

Thompson, Kim-Ly 24 December 2018 (has links)
The academic community and government agencies are increasingly recognizing how Indigenous knowledge can enrich environmental monitoring and inform adaptation in complex social-ecological systems. Indeed, Indigenous peoples have been monitoring, managing, and adapting to their environments for thousands of years. Despite the impacts of ongoing colonialism, many Indigenous peoples continue to monitor and exert their knowledge and governance systems through ongoing use and relationship with their traditional territories. This Master’s research grew from the Gitga’at First Nation’s Oceans and Lands Department desire to formally include the knowledge and observations of their land and sea users as part of contemporary stewardship initiatives. The primary objective of this research was to provide a framework for an ongoing monitoring system based in the observations and knowledge of Gitga’at harvesters. In order to meet this objective, I asked three main research questions: 1. How has Indigenous knowledge interacted with environmental monitoring initiatives, and what are characteristics of effective and self-sustaining monitoring initiatives that engage Indigenous knowledge?; 2. What methods of Indigenous knowledge documentation and communication are best suited to the needs and objectives of the Gitga’at First Nation?; and 3. How does ongoing use and occupancy of Gitga’at territory inform community-based monitoring? I first conducted a review of the literature on Indigenous knowledge and environmental monitoring to explore the ways in which Indigenous peoples and their knowledges have been engaged in other monitoring initiatives. I found that Indigenous knowledge has been engaged in a number of ways ranging from traditional land-based activities providing holistic social-ecological monitoring indicators, to the employment of Indigenous field technicians for externally-drive monitoring initiatives. Effective projects involved high degrees of community participation or direction; were built on partnerships based on trust and respect for various knowledge systems; used multiple methods to document and communicate Indigenous knowledge; and had institutional links between monitoring and management bodies. To answer my second research question, I followed a participatory case study approach in partnership with Gitga’at co-researchers. We began with informal interviews with 36 knowledge holders to gauge interest in the project and to establish monitoring objectives. These were followed by two community meetings and 12 workshops to design methods for documenting their observations. We then iteratively designed and tested these methods over the course of two traditional harvest seasons. We interviewed 23 participants following the spring 2017 harvest season and 27 after the fall/winter 2017 harvest season. We also conducted 4 semi-structured interviews with department leaders to ensure that the information gathered was meeting the needs of the Gitga’at Oceans and Lands Department, Treaty Negotiators, the Hartley Bay School and the Gitga’at Health Department. Key outcomes are a harvest logbook, and an interview guide to be administered by community researchers following each harvest season. To answer my third research question, I conducted a conceptual framework analysis on the notes and transcripts taken while designing and testing a monitoring program based in the observations and knowledge of Gitga’at land and sea users. An interconnected set of social-ecological concepts and indicators that are monitored by Gitga’at harvesters emerged. The framework I developed based on conversations about Gitga’at monitoring through harvesting activities highlights the importance of maintaining and revitalizing Indigenous knowledge and harvesting practices in order to continue social-ecological monitoring, as well as opportunities for scientific approaches to situate themselves within Indigenous frameworks and priorities. This research provides the Gitga’at First Nation with foundations from which to pursue ongoing documentation of observations and knowledge produced through harvesting activities as a form of social-ecological monitoring. It also serves as a guide for other Indigenous nations that wish to embark on similar initiatives. Amidst discussions of marine and coastal resource co-management in British-Columbia and Indigenous resurgence, this research adds to the literature that re-enforces the importance of Indigenous governance and access to their lands and waters, and the continuation of Indigenous relationships to the land and sea in order to inform social-ecological monitoring for the benefit of all. / Graduate

Measuring the Sustainability of Protected Area-Based Tourism Systems: A Multimethod Approach

January 2014 (has links)
abstract: This research assessed the sustainability of protected area-based tourism systems in Nepal. The research was composed of three interrelated studies. The first study evaluated different approaches to protected area governance. This was a multiple-case study research involving three protected areas in Nepal: the Annapurna Conservation Area, Chitwan National Park, and the Kanchenjunga Conservation Area. Data were collected from various published and unpublished sources and supplemented with 55 face-to-face interviews. Results revealed that outcomes pertaining to biodiversity conservation, community livelihoods, and sustainable tourism vary across these protected areas. The study concluded that there is no institutional panacea for managing protected areas. The second study diagnosed the sustainability of tourism in two destination communities: Ghandruk and Sauraha, which are located within the Annapurna Conservation Area and Chitwan National Park, respectively. A systemic, holistic approach--the social-ecological system framework--was used to analyze the structures, processes, and outcomes of tourism development. Data collection involved 45 face-to-face semi-structured interviews and a review of published and unpublished documents. Results revealed that tourism has several positive and a few negative sociocultural, economic, and ecological outcomes in both communities. Overall, tourism has progressed towards sustainability in these destinations. The third study examined tourism stakeholders' perspectives regarding sustainable tourism outcomes in protected areas. The study compared the responses of residents with residents, as well as tourists with tourists, across the Annapurna Conservation Area and Chitwan National Park. Tourism sustainability was evaluated with six tourism impact subscales measuring negative and positive ecological, economic, and social impacts. Data were collected using the survey method. Respondents included 230 residents and 205 tourists in Annapurna, and 220 residents and 210 tourists in Chitwan. The findings revealed that the residents across these protected areas perceived positive and negative impacts differently, as did the tourists, suggesting that the form of tourism development affects the sustainability outcomes in protected areas. Overall, this research concluded that protected areas and tourism are intricately related, and sustainable management of a protected area-based tourism system requires a polycentric adaptive approach that warrants a broad participation of relevant stakeholders. / Dissertation/Thesis / Doctoral Dissertation Community Resources and Development 2014

Ecology and the City: A Long-Term Social-Ecological Examination of the Drivers and Diversity of Urban Vegetation

January 2015 (has links)
abstract: Often, when thinking of cities we envision designed landscapes, where people regulate everything from water to weeds, ultimately resulting in an ecosystem decoupled from biophysical processes. It is unclear, however, what happens when the people regulating these extensively managed landscapes come under stress, whether from unexpected economic fluctuations or from changing climate norms. The overarching question of my dissertation research was: How does urban vegetation change in response to human behavior? To answer this question, I conducted multiscale research in an arid urban ecosystem as well as in a virtual desert city. I used a combination of long-term data and agent-based modeling to examine changes in vegetation across a range of measures influenced by biophysical, climate, institutional, and socioeconomic drivers. At the regional scale, total plant species diversity increased from 2000 to 2010, while species composition became increasingly homogeneous in urban and agricultural areas. At the residential scale, I investigated the effects of biophysical and socioeconomic drivers – the Great Recession of 2007-2010 in particular – on changing residential yard vegetation in Phoenix, AZ. Socioeconomic drivers affected plant composition and increasing richness, but the housing boom from 2000 through 2005 had a stronger influence on vegetation change than the subsequent recession. Surprisingly, annual plant species remained coupled to winter precipitation despite my expectation that their dynamics might be driven by socioeconomic fluctuations. In a modeling experiment, I examined the relative strength of psychological, social, and governance influences on large-scale urban land cover in a desert city. Model results suggested that social norms may be strong enough to lead to large-scale conversion to low water use residential landscaping, and governance may be unnecessary to catalyze residential landscape conversion under the pressure of extreme drought conditions. Overall, my dissertation research showed that urban vegetation is dynamic, even under the presumably stabilizing influence of human management activities. Increasing climate pressure, unexpected socioeconomic disturbances, growing urban populations, and shifting policies all contribute to urban vegetation dynamics. Incorporating these findings into planning policies will contribute to the sustainable management of urban ecosystems. / Dissertation/Thesis / Doctoral Dissertation Biology 2015

The Semiotic Nature of Power in Social-Ecological Systems

January 2017 (has links)
abstract: Anderies (2015); Anderies et al. (2016), informed by Ostrom (2005), aim to employ robust feedback control models of social-ecological systems (SESs), to inform policy and the design of institutions guiding resilient resource use. Cote and Nightingale (2012) note that the main assumptions of resilience research downplay culture and social power. Addressing the epistemic gap between positivism and interpretation (Rosenberg 2016), this dissertation argues that power and culture indeed are of primary interest in SES research. Human use of symbols is seen as an evolved semiotic capacity. First, representation is argued to arise as matter achieves semiotic closure (Pattee 1969; Rocha 2001) at the onset of natural selection. Guided by models by Kauffman (1993), the evolution of a symbolic code in genes is examined, and thereon the origin of representations other than genetic in evolutionary transitions (Maynard Smith and Szathmáry 1995; Beach 2003). Human symbolic interaction is proposed as one that can support its own evolutionary dynamics. The model offered for wider dynamics in society are “flywheels,” mutually reinforcing networks of relations. They arise as interactions in a domain of social activity intensify, e.g. due to interplay of infrastructures, mediating built, social, and ecological affordances (An- deries et al. 2016). Flywheels manifest as entities facilitated by the simplified interactions (e.g. organizations) and as cycles maintaining the infrastructures (e.g. supply chains). They manifest internal specialization as well as distributed intention, and so can favor certain groups’ interests, and reinforce cultural blind spots to social exclusion (Mills 2007). The perspective is applied to research of resilience in SESs, considering flywheels a semiotic extension of feedback control. Closer attention to representations of potentially excluded groups is justified on epistemic in addition to ethical grounds, as patterns in cul- tural text and social relations reflect the functioning of wider social processes. Participatory methods are suggested to aid in building capacity for institutional learning. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2017

Social-Ecologies of Crisis: Assessing the Back-to-Land Movement in Greece

January 2018 (has links)
abstract: Adaptation and transformation have emerged as a key themes for human-environment research, especially in the context of rapid social-ecological changes. The 2008 global financial crisis constitutes a major driver of change with social-ecological ramifications that have yet to be fully explored. Using Greece, the poster child of the euro-crisis as a case-study, this dissertation examines how adaptive capacity is mobilized and even enhanced in times of crisis, paying particular attention to the role played by natural capital. To do so, I focus on the back-to-land trend whereby urbanites seek to engage in food production post-crisis (2008-onwards). In-depth qualitative analysis of back-to-landers’ motivations, experiences, and challenges is integrated with quantitative data about household demographics, incomes and assets, and land management characteristics. The dissertation is organized in three main result papers (chapters). The first seeks to understand why people turn to the land in times of crisis, and the role played by agency. The second analyzes the various assets that people mobilize in order to go back to the land, paying particular attention to the different mobilities necessary for their livelihood transformation. The third examines environmental safety nets in terms of material and non-material benefits that ecosystems provide to people. This research contributes to a wider social-ecological scholarship that seeks to understand how people adapt and transform when confronted with crises, focusing on how land and associated ecosystem services contribute to the resilience of these households, and the role played by agency in this process. / Dissertation/Thesis / Doctoral Dissertation Geography 2018

The Consequences of Human land-use Strategies During the PPNB-LN Transition: A Simulation Modeling Approach

January 2013 (has links)
abstract: This dissertation investigates the long-term consequences of human land-use practices in general, and in early agricultural villages in specific. This pioneering case study investigates the "collapse" of the Early (Pre-Pottery) Neolithic lifeway, which was a major transformational event marked by significant changes in settlement patterns, material culture, and social markers. To move beyond traditional narratives of cultural collapse, I employ a Complex Adaptive Systems approach to this research, and combine agent-based computer simulations of Neolithic land-use with dynamic and spatially-explicit GIS-based environmental models to conduct experiments into long-term trajectories of different potential Neolithic socio-environmental systems. My analysis outlines how the Early Neolithic "collapse" was likely instigated by a non-linear sequence of events, and that it would have been impossible for Neolithic peoples to recognize the long-term outcome of their actions. The experiment-based simulation approach shows that, starting from the same initial conditions, complex combinations of feedback amplification, stochasticity, responses to internal and external stimuli, and the accumulation of incremental changes to the socio-natural landscape, can lead to widely divergent outcomes over time. Thus, rather than being an inevitable consequence of specific Neolithic land-use choices, the "catastrophic" transformation at the end of the Early Neolithic was an emergent property of the Early Neolithic socio-natural system itself, and thus likely not an easily predictable event. In this way, my work uses the technique of simulation modeling to connect CAS theory with the archaeological and geoarchaeological record to help better understand the causes and consequences of socio-ecological transformation at a regional scale. The research is broadly applicable to other archaeological cases of resilience and collapse, and is truly interdisciplinary in that it draws on fields such as geomorphology, computer science, and agronomy in addition to archaeology. / Dissertation/Thesis / Ph.D. Anthropology 2013

Nature itself as our guide : A resilience perspective on permaculture and an empirical investigation of its use in three case studies in British Columbia, Canada

Noga, Audrey January 2012 (has links)
In general, small farms have significant social and ecological advantages over industrialized large farms. However, a combination of complex pressures is making it difficult for many small-scale farmers to stay in business – including in Canada, where this thesis is focused. The consequential loss of many small farms results in a general loss of diversity and a decreased flexibility for future options for food procurement for many communities. Creating more and increasingly sustainable options for food procurement is progressively more important in the face of rising food and fuel prices, degradation of ecosystem services, and the increase of extreme climate fluctuations. For these and other reasons, creating social-ecological resilience in small farming systems is key to ensuring more options for long-term food procurement.Permaculture – the design and maintenance of agriculturally productive ecosystems based on the patterns and relationships found in natural ecosystems – has been identified in the literature as a potential tool to build social-ecological resilience in small scale farming systems. This study evaluates permaculture from a resilience perspective, and compares the analysis to permaculture use on three farms in British Columbia (BC). This has been done in order to understand whether or not the practice contributes to the social-ecological resilience of the small farming systems in which it is used, and if so, how.Results imply that permaculture use does in fact increase social-ecological resilience of small farms by encouraging ecological, social and economical diversity – creating buffer zones that allow for flexibility and augmented future options for the farm and also potentially for the community in which the farm operates. It has been shown that the key actors in each case study fundamentally place a strong emphasis on the importance of human and environmental health – while recognizing the need to address the interrelated nature of social and ecological issues. A strong social connection in the local community and connections in the global community are of high importance because of the support provided to actors, and diverse sources of income that are related to the structure of the farm are also shown to be key elements in each case. It would be valuable for continuing study to aim to uncover how permaculture can be used on a larger scale without loosing its social and ecological benefits.

Theories of (Un)sustainable Consumption

Spash, Clive L., Dobernig, Karin January 2017 (has links) (PDF)
In this discussion paper we review and contrast alternative theories of consumption in terms of the intellectual basis they provide for understanding sustainable behaviours. A defining aspect of the modern literature in this field is the emphasis on the individual as a volitional agent who engages wilfully in the decision to consume. This is in stark contrast to earlier literature that concentrated on the structural lock-in of individuals to undesirable consumption patterns and the powers of corporations in creating consumer demand for their products and services. We argue that, in order to unravel consumption in its full complexity, and as a matter of utmost importance, understanding must include both the buy-in of individual agents, whose consumption activities contribute to their self-identity, and the structure imposed by the institutions of society, that frame the context of actors' decisions. More than this, any move away from the current unsustainable consumption patterns prevalent in modern societies requires a richer conceptualisation of consumption that involves an awareness and examination of the political economy in which humans live. / Series: SRE - Discussion Papers
