Nautical Narratives on the Island of Newfoundland: Exploring the Fishing Industry and Reimagining Changing Futures

Drodge, Kassandra 16 January 2024 (has links)
Thirty (30) years have passed since the cod collapse in Newfoundland and Labrador. The cod collapse left fifteen thousand (15,000) people who made a living off harvesting and processing cod without jobs, and almost eliminated a singular fish species from Newfoundland and Labrador (Bavington, 2010). The cod collapse created many policy changes and ripples of generational disruption in individual livelihoods and inshore/coastal fishing practices among families. Harvesting cod from the waters of Newfoundland goes back for hundreds of years, and many fishers and coastal communities still depend on it today. A significant amount of research on the history of cod fishing, the 1992 cod collapse, and the almost annihilation of a species (Bavington, 2010); but there is room to further explore how local fishers and fishing communities live today. I argue that there is a need to increase local consultation during inshore/coastal fishery policy amendment processes and local engagement with environmental assessment methods in Newfoundland specifically. The thesis critically breaks down industrial ecological systems and looks at how industrial fishing has created a series of policies, regulations, and systems that have historically influenced the contingency of the inshore/coastal fishery. The local stories captured in this thesis represent hopeful futures that reconcile ways to resolve problems within regulatory fishing systems and highlight individual and collective frustrations with licensing, fishing regions, catch quotas, and environmental assessments that inform policy.

Climate Change Impacts in Hydrology: Quantification and Societal Adaptation

Serrat Capdevila, Aleix January 2009 (has links)
The research presented here attempts to bridge science and policy through the quantification of climate change impacts and the analysis of a science-fed participatory process to face a sustainability challenge in the San Pedro Basin (Arizona). Paper 1 presents an assessment of a collaborative development process of a decision support system model between academia and a multi-stakeholder consortium created to solve water sustainability problems in a local watershed. This study analyzes how science-fed multi-stakeholder participatory processes lead to sustainability learning promoting resilience and adaptation. Paper 2 presents an approach to link an ensemble of global climate model outputs with a hydrological model to quantify climate change impacts in the hydrology of a basin, providing a range of uncertainty in the results. Precipitation projections for the current century from different climate models and IPCC scenarios are used to obtain recharge estimates as inputs to a groundwater model. Quantifying changes in the basin's water budget due to changes in recharge, evapotranspiration (ET) rates are assumed to depend only on groundwater levels. Picking on such assumption, Paper 3 explores the effects of a changing climate on ET. Using experimental eddy covariance data from three riparian sites, it analyzes seasonal controls on ET. An approach to quantify evapotranspiration rates and growing season length under warmer climates is proposed. Results indicate that although atmospheric demand will be greater, increasing pan and reference crop evaporation, ET rates at the studied field sites will remain unchanged due to stomatal regulation. However, the length of the growing season will increase, mainly with an earlier leaf-out and at a lesser level by a delayed growing season end. These findings - implying decreased aquifer recharge, increased riparian water use and a lesser water balance - are very relevant for water management in semi-arid regions. Paper 4, in which I am second author, explores the theory relating changes in area-average and pan evaporation. Using the same experimental data as Paper 3, it corroborates a previous theoretical relationship and discusses the validity of Bouchet's hypothesis.

A governança e a sustentabilidade do extrativismo do jaborandi na Amazônia e transição para o Cerrado e a Caatinga

Grabher, Cristina January 2015 (has links)
O extrativismo apresenta-se como uma oportunidade de ação que contribui para o desenvolvimento rural sustentável. O extrativismo do jaborandi representa um recurso de natureza comum, governado por diversos atores e sob influência do mercado. O jaborandi, Pilocarpus microphyllus Stapf ex Wardlew, é um arbusto que ocorre no sub-bosque de florestas na região de transição entre os biomas Amazônia, Cerrado e Caatinga. Das suas folhas, é extraída a pilocarpina, usada, principalmente, no tratamento do glaucoma. As folhas do jaborandi são oriundas, em sua maioria, do extrativismo, no Piauí, Maranhão e Pará. O objetivo deste estudo foi compreender o sistema socioecológico (SES) e a governança do extrativismo do jaborandi e sua influência sobre a sustentabilidade da atividade na Amazônia e áreas de transição com o Cerrado e Caatinga. Já os objetivos específicos foram: 1) descrever os SESs do extrativismo do jaborandi; 2) caracterizar a governança dos SESs; 3) analisar a relação da governança dos diferentes SESs com a sustentabilidade do extrativismo do jaborandi. Para tanto, utilizou-se o Institutional Analysis & Development - IAD framework e os princípios de governança dos SESs robustos, analisando a governança e a sustentabilidade do SES do extrativismo do jaborandi. Esta pesquisa caracteriza-se como um estudo de análise institucional multiescalar, sendo a maior escala o Sistema Socioecológico “extrativismo do jaborandi”, considerada como toda a área de ocorrência do extrativismo. A escala mediana, regional, os dois subsistemas que correspondem à região amazônica e transição. O nível local foi caracterizado por quatro subsistemas socioecológicos: SES Agroextrativista Cocais, SES Agroextrativista Pluriétnico Transição, SES Expedicionário Pluriétnico Amazônia e SES Expedicionário Flona Carajás Amazônia. Os métodos constaram de análises qualitativas de dados secundários e dados primários - coletados em entrevistas realizadas com os atores do extrativismo do jaborandi. Observou-se a influência das políticas desenvolvimentistas sobre a devastação de parte da matriz florestal de ocorrência do jaborandi. Além disso, o mercado de pilocarpina teve larga influência sobre o extrativismo, com destaque para a domesticação da espécie e o desenvolvimento da pilocarpina sintética. Desde o ano de 2009, o Projeto de Valorização do Jaborandi também influencia o extrativismo, em busca de tornar a atividade mais sustentável. Identificou-se diferença de capacidade de suporte das populações de jaborandi entre o Subsistema Socioecológico Transição, que apresenta baixa capacidade, devido às condições edafoclimáticas mais severas, ao Subsistema Amazônia, onde as condições são mais favoráveis. Na região de transição, os extrativistas são agricultores familiares e residem próximos ao recurso, enquanto que, na Amazônia, os extrativistas, em sua maioria, são urbanos e, para acessarem o recurso, precisam organizar-se em equipes e fazerem uma expedição até as áreas de manejo, que são distantes e são áreas protegidas. Ao caracterizar a governança multiescalar dos SESs, encontrou-se um complexo arranjo institucional, composto por regras formais e informais de múltiplos níveis. Muitas das regras não são colocadas em uso, atribui-se esse fenômeno a não participação dos extrativistas na formulação dessas regras, à falta de monitoramento e sanções efetivas. Percebeu-se que quando os extrativistas participam de arenas de escolha coletiva, eles têm maiores ganhos. Evidenciou-se que onde há participação governamental, há maior governança. Ao analisar a relação da governança dos diferentes SES com a sustentabilidade, ficou evidente que o SES Expedicionário Flona Carajás Amazônia é mais sustentável do que os SES Agroextrativista Cocais e SES Agroextrativista Pluriétnico Transição, onde a capacidade de suporte e os arranjos institucionais são frágeis. Enquanto que o SES Expedicionário Pluriétnico Amazônia é parcialmente sustentável, por fragilidades de acesso ao recurso. Conclui-se que a governança, através das organizações e arranjos institucionais, bem como os SES, principalmente no que se refere à capacidade de suporte, atores envolvidos e organização social, influenciam na sustentabilidade das múltiplas escalas do extrativismo do jaborandi. / Forest management of non-wood products has the potential to contribute to sustainable rural development. The forest management of jaborandi is a common-pool resource, governed by different actors and under the influence of market. Jaborandi, Pilocarpus microphyllus Stapf ex Wardlew, is a scrub that occurs in the forest floor of forests in the transition region between the biomes of Amazon, Cerrado and Caatinga. Pilocarpine, which is extracted from its leaves, is used mainly in the treatment of glaucoma. The jaborandi leaves come, mostly, from forest management in Piauí, Maranhão and Pará. The objective of this study was to understand the socio-ecological system (SES) and the governance of jaborandi’s management and its influence on the sustainability of the activity in the Amazon and transition areas of the Cerrado and Caatinga. The specific objectives were: 1) to describe the SES of jaborandi´s management; 2) to characterize the governance of the SESs; 3) to analyse the relationship of the governance of different SESs with the sustainability of jaborandi´s management. For this purpose, the IAD framework and the principles of governance of robust SESs were used, analysing the governance of SESs and the sustainability of jaborandi´s management. This research is a study of multiescalar institutional analysis, in which the major scale is the socio-ecological system “jaborandi´s management”, which covers the entire area of leaves collection. The median scale, regional, are the two subsystems that are the Amazon and Transition region. The local level was characterized by four socio-ecological subsystems: Agroextractivist Cocais, Agroextractivist Multiethnic Transition, Expeditionary Multiethnic Amazon and Expeditionary Flona Carajás Amazon. The methods consisted of qualitative analysis of secondary data and primary data - collected in interviews with the actors of the jaborandi´s management. The influence of developmentalism policies was observed over the devastation of part of the forest area of the jaborandi´s occurrence. In addition, the pilocarpine market had wide influence on the jaborandi´s management, highlighting the domestication of the species and the development of synthetic pilocarpine. Since year 2009, Projeto de Valorização do Jaborandi (Jaborandi Enhancement Project) has also influenced the management, seeking to make the activity more sustainable. There was a difference in the support capacity of populations between jaborandi Subsystem socioecological Transition, which has low capacity due to the most severe climate and soil conditions, and the Amazon subsystem, where conditions are more favorable. In the transition region, the leaves collectors are family farmers and reside near the resource, while in the Amazon, the leaves collectors are mostly urban dwellers and to access the resource they need to organize themselves into teams and make an expedition to the harvesting areas, which are distant and protected areas. To characterize the multiescalar governance of SES, a complex institutional arrangement has been identified, consisting of formal and informal rules of multiple levels. Many of the rules are not applied, which phenomenon is attributed to the non-participation of leaves collectors in the formulation of these rules, the lack of monitoring and effective sanctions. It has been observed that when the leaves collectors participate in collective choice arenas, they have greater benefits. It has been perceived that where there is government close participation, there is greater governance. By analysing the relationship of the governance of different SESs and sustainability, it became clear that the SES Expeditionary Flona Carajás Amazon is more sustainable than the SES Agroextrativist Cocais and SES Agroextrativist Multiethnic Transition, where the support capacity and institutional arrangements are fragile. While the SES Expeditionary Multiethnic Amazon is partially sustainable, there are weaknesses in access to the resource. The conclusion points out that the governance, through organizations and institutional arrangements, as well as the SES, especially with regard to support capacity, stakeholders involvement and social organization, influence the sustainability of multiple scales of jaborandi´s management.

Commons Governance for Robust Systems: Irrigation Systems Study Under a Multi-Method Approach

January 2017 (has links)
abstract: Sustainability depends in part on our capacity to resolve dilemmas of the commons in Coupled Infrastructure Systems (CIS). Thus, we need to know more about how to incentivize individuals to take collective action to manage shared resources. Moreover, given that we will experience new and more extreme weather events due to climate change, we need to learn how to increase the robustness of CIS to those shocks. This dissertation studies irrigation systems to contribute to the development of an empirically based theory of commons governance for robust systems. I first studied the eight institutional design principles (DPs) for long enduring systems of shared resources that the Nobel Prize winner Elinor Ostrom proposed in 1990. I performed a critical literature review of 64 studies that looked at the institutional configuration of CIS, and based on my findings I propose some modifications of their definitions and application in research and policy making. I then studied how the revisited design principles, when analyzed conjointly with biophysical and ethnographic characteristics of CISs, perform to avoid over-appropriation, poverty and critical conflicts among users of an irrigation system. After carrying out a meta-analysis of 28 cases around the world, I found that particular combinations of those variables related to population size, countries corruption, the condition of water storage, monitoring of users behavior, and involving users in the decision making process for the commons governance, were sufficient to obtain the desired outcomes. The two last studies were based on the Peruvian Piura Basin, a CIS that has been exposed to environmental shocks for decades. I used secondary and primary data to carry out a longitudinal study using as guidance the robustness framework, and different hypothesis from prominent collapse theories to draw potential explanations. I then developed a dynamic model that shows how at the current situation it is more effective to invest in rules enforcement than in the improvement of the physical infrastructure (e.g. reservoir). Finally, I explored different strategies to increase the robustness of the system, through enabling collective action in the Basin. / Dissertation/Thesis / Doctoral Dissertation Sustainability 2017

Collaborative Governance in the Rideau Canal: Barriers and Opportunities

Mistry, Isha 21 December 2020 (has links)
The environmental management of watersheds presents a complex governance issue due to their large spatial scales that include overlapping jurisdictions, competing interests in resource use, and lack of coordination among stakeholders. The Rideau Canal, spanning 200 km between the cities of Ottawa and Kingston, is an interesting case study as it is a multi-watershed system over which municipal, provincial and federal governments have authority. However, these governments have been unsuccessful in addressing system-wide issues such as shoreline development, erosion and invasive species that have significantly impacted the ecological integrity of the canal. A shift toward polycentric governance, which are systems of multi-scale governance, in which well-informed publics can contribute to the Rideau Canal’s management is required. This thesis examines how co-governance can be conceptualized for the RC by (1) analyzing convergences in stakeholder perspectives about the environment and governance, and (2) comparing collaborative causal mapping exercises with various stakeholders to current government engagement efforts. A tiered co-governance framework that intentionally links existing small-scale activities to system-wide formal venues of knowledge sharing could democratize environmental governance on the Rideau Canal to improve its management. Beyond its practical contributions, this research also contributes to developing the academic literature on co-governance for multi-watershed waterways that have both constructed and natural aspects.

A pesca nos manguezais no Estuário do Rio São Francisco: uma abordagem sócio-ecológica com ênfase no caranguejo Ucides cordatus (Linnaeus, 1763) / Mangrove fisheries in the São Francisco River Estuary (Northeastern, Brazil): a socio-ecological approach with emphasis on the mangrove crab Ucides cordatus (Linnaeus, 1763)

Santos, Luciana Cavalcanti Maia 26 January 2015 (has links)
No Nordeste do Brasil, o estuário do Rio São Francisco apresenta extensas áreas de manguezais (32 km2) cujos recursos são utilizados por populações humanas. Este estudo considerou a metodologia de sistemas sócio-ecológicos complexos para analisar a pesca nos manguezais desse estuário, com ênfase no caranguejo Ucides cordatus. Por meio da integração de dados de diferentes áreas (etnobiologia, levantamentos socioeconômicos, estrutura populacional do caranguejo, características da vegetação, arranjo espacial da paisagem, sensoriamento remoto e geoprocessamento) em uma análise multicritério foi determina e mapeada a aptidão dos manguezais para a conservação e a pesca dessa espécie. Uma diversidade de recursos pesqueiros do manguezal (por exemplo, peixes, caranguejos e moluscos), constitui a principal base da economia de subsistência local, em que o caranguejo U. cordatus é o mais importante. As populações locais possuem um vasto conhecimento sobre o tamanho populacional e corporal, ciclo de vida, diferenciação sexual e habitat dessa espécie, e aplicam práticas conservacionistas no uso da redinha. A estrutura populacional do caranguejo revelou um alto potencial pesqueiro, com maior abundância de caranguejos de tamanho comercial do que os de tamanho não comercial. Os manguezais mais aptos para a conservação de U. cordatus (9,4 km2) estão localizados próximos à foz e apresentam alta abundância de caranguejos não comerciais, baixa densidade de caranguejos comerciais e baixo grau de utilização para a pesca. Os manguezais mais aptos para a pesca (10,2 km2) estão distantes da foz e apresentam alta abundância de caranguejos de tamanho comercial, baixa densidade de caranguejos em tamanho não comercial, caranguejos grandes, médio a alto grau de uso e estão próximos aos povoados. Os mapas de aptidão gerados podem auxiliar as agências governamentais no delineamento de áreas extrativistas e de exclusão da pesca, como sugerido no Plano Nacional de Gestão para o Uso Sustentável do Caranguejo-uçá / In Northeastern Brazil, the São Francisco River Estuary comprises a significant mangrove area (32 km2) used by local human populations. This study considered the framework of socio-ecological systems to analyze the mangrove fishery in this estuary, with emphasis on the crab Ucides cordatus. By the integration of data from different fields (etnobiology and socio-economic surveys, crab population structure, vegetation features, landscape arrangement, remote sensing and geoprocessing) in a multi-criteria analysis, we determined and mapped the suitability of the mangroves for the conservation and fishery of this species. We found that a diversity of mangrove fisheries (e.g. fish, crabs and mollusks) constitute the main base of the local subsistence economy, wherein the Ucides cordatus is the most important. The local populations have a substantial knowledge about this crab population and body sizes, life cycle, sexual differentiation, behavior and habitat, and apply conservation practices in the use of the \"redinha\". The population structure of the crab U. cordatus revealed a high fishery potential, with higher abundance (frequency and density) of crabs in commercial size than the non-commercial sized crabs. The mangroves more suitable for the crab conservation (9.4 km2) are those close to the river mouth, showing high abundance of non-commercial crabs, low density of commercial crabs and low degree of use for fishery. On the other hand, the mangroves more suitable for the crab fishery (10.2 km2) are those located far from to river mouth, showing high density and frequency of crabs in commercial size, low density of crabs in non-commercial size, big sized crabs, medium to high degree of use, and are close to the fishery villages. The maps of suitability can aid government agencies in delineating extractive and fishery exclusion areas, as stated by the Proposal of a National Management Plan for this crab, in order to achieve a sustainable fishery

Gestão de recursos comuns no entorno de áreas protegidas : ação coletiva e desenvolvimento rural no sistema sócioecológico (SES) do Parque Nacional da Serra da Bodoquena - MS

Pereira, Márcio de Araújo January 2013 (has links)
Esta tese tem como tema o conjunto de recursos comuns naturais e os formatos de gestão que permitem novos sistemas de governança nos espaços rurais no entorno de áreas protegidas. Como questão central, busca responder como os diversos atores afetados pelo processo de criação de uma área protegida organizam-se e desenvolvem ações coletivas para a gestão dos recursos comuns no entorno destas áreas. Têm-se como hipótese que há uma aproximação entre os atores conforme seus objetivos em relação aos recursos comuns naturais, o que remete a configuração de um novo sistema de governança que propicia o desenvolvimento de ações coletivas próprias de gestão dos recursos comuns. Outra hipótese é que a ação do Estado, por meio de políticas governamentais, apresenta efeito limitado na coordenação das ações e na promoção do consenso entre os atores. Desta forma, o objetivo deste trabalho é estudar a ação coletiva dos atores sociais na gestão dos recursos comuns no entorno do Parque Nacional da Serra da Bodoquena (PNSB), o qual abrange áreas dos municípios de Bodoquena, Bonito, Jardim e Porto Murtinho no Estado de Mato Grosso do Sul. Por meio da abordagem institucional no estudo da auto-organização e autogovernança em situações de gestão do conjunto de recursos comuns desenvolvida por Elinor Ostrom, buscou-se a fundamentação teórica para explicação dos fenômenos e problemática identificada. Metodologicamente trata-se de uma pesquisa de campo e documental, a qual apresenta um delineamento de estudo de caso small-N, aplicando-se o framework para análise de sistemas sócio-ecológicos (SES), procedendo-se também uma sistemática análise documental próxima à meta-análise. Conclui-se que a esperada mobilização de grupos de indivíduos em busca de objetivos comuns encontra duas vertentes neste caso, com os participantes da arena de ação criando distintos objetivos e distintas ações coletivas de acordo com seus interesses, produtivos ou ambientais, sendo que governo dos comuns permanece sob o controle dos interesses produtivistas arraigados na cultura de produção agropecuária local. / This thesis has as its theme the common natural resources and the management models that allow new governance systems in the rural areas in the surrounding of protected areas. As central question, seeks to answer how the various actors affected by the process of creation of a protected area organise themselves and develop collective actions for the management of common natural resources in the surroundings of this area. There has been hypothesised that there is a closeness among the actors as their goals in relation to common natural resources, which refers to setting up a new governance system that promotes the development of collective actions specific to the management of common resources. Another hypothesis is that state action, through government policies, has limited effect on the coordination and promotion toward a consensus among actors. In this sense, the objective of this work is to study the collective action of social actors in the management of common natural resources in the surroundings of the National Park of Serra da Bodoquena (PNSB), which covers areas of the municipalities of Bodoquena, Bonito, Jardim and Porto Murtinho in the State of Mato Grosso do Sul. Based on institutional approach for the study of the self-organisation and self-governance in common-pool resources situations developed by Elinor Ostrom, the investigation sought the theoretical explanation of phenomena and problem identified. Methodologically this is a documentary and field research, which has a feature of small-N case of study, proceeding an applying of the framework for analysing social-ecological systems (SES), conducting also a systematic analysis of documents close to a meta-analysis. The conclusions point out that the expected mobilisation of groups of individuals in the pursuit of common goals is twofold in this case, with the participants of the action arena creating different goals and different collective actions according to their interests, environmental or productive, and that the govern of the commons remains under the control of agribusiness interests rooted in the culture of the local agricultural production.

Challenges and Opportunities Facing Local Governance Agents in Advancing an Ecosystem Approach to Conceptualizing and Governing Community Health in Norfolk County, Ontario

Edge, Sara January 2007 (has links)
This research focuses on the challenges and opportunities facing local governance agents in advancing an ecosystem approach to conceptualizing and governing community health in Norfolk County, Ontario. Norfolk County is a rural, agriculturally-based community dependent upon tobacco production. This industry has collapsed, triggering widespread socioeconomic impacts and community health pressures. The government is searching for alternative modes of economic development and tensions are high with respect to the direction and nature of these developments. Some citizens are concerned about the security of their rural livelihoods. Others are concerned about ecological integrity. Still others are convinced of the need for aggressive economic growth. Local decision-makers are struggling to meet all of these requirements. An ecosystem approach views health as part of the broader socio-ecological system, recognizing that health outcomes are by-products of complex biophysical, social, political and economic system interactions at nested spatial and temporal scales. The approach contrasts with conventional health models, which tend to be reactionary, narrowly focused, and short-sighted. Such models are typical of the hierarchical, technocratic nature of public administration which renders decision-making structures and processes ill equipped to deal with complex problems. More systemic, integrated, participatory and collaborative approaches to decision-making are needed in order to better address the complexities involved in facilitating healthy and sustainable community development. Additionally, governance agents must also be able to embrace and navigate these evolving approaches to health conceptualization and governance. An investigation into Norfolk County grounds this analysis by revealing the challenges and opportunities facing local governance agents in advancing an ecosystem approach. The case study research effectively tests the utility and feasibility of the ecosystem approach through a qualitative analysis. The research contributes criteria required for advancing an ecosystem approach to community health governance and practice and empirically tests them within the context of Norfolk County.
