Empirical evidence of the role of Ecosystem-Based Management in qualifying Marine Environmental Impact Assessment / Evidência empírica do papel da abordagem baseada em ecossistemas na qualificação da avaliação de impacto ambiental marinhaAndrade, Mariana Martins de 03 May 2018 (has links)
Externalities caused by human transformations in ecosystems structure and functioning has been threatening environmental quality and social welfare in all socioecological systems, including coastal zones. Environmental Impact Assessment (EIA) is an instrument widely used to evaluate the feasibility of developments and projects that can potentially provoke changes in biophysical-human environment. However, EIA generic and fragmented approach has not properly been considering people and environmental particularities, such processes and benefits to society, in decision making. Ecosystem-Based Management recently emerged as a strategy that can qualify EIA, by embracing ecosystem processes and services (ES), human dimensions, social engagement and Local, Traditional and Scientific Ecological Knowledge. Using a case study of a contested Port expansion in São Sebastião, São Paulo, Brazil, that endangered the sustainability of an adjacent bay (Araçá Bay), we selected analytical categories comprising different stakeholders, ecosystem services and disturbances scenarios to understand the role of EBM in coastal EIA. We presumed that stakeholders with deeper relationships with the place could provide more comprehensive assessments about changes in the availability of main local ES, as a result of greater sense of place, access to different sources of knowledge and opportunities to social participation. Also, an EBM approach would provide a more robust, i.e., a wider and more integrated assessment of impacts in the provision of the ES than the Environmental Impact Study (EIS) of the port expansion. We performed in-depth interviews with four different groups of stakeholders and analyzed their speeches with discourse analysis and statistical inquiries to assess ES scores of occurrences in current (Two-way ANOVA) and disturbances scenarios (Repeated measures ANOVA and PERMANOVA), besides their main argumentation patterns. We compared these results with the port expansion EIS to assert to robustness of the method. The groups had different perceptions from each other, which depended on the scenario and ES evaluated. We corroborated the hypotheses: groups\' closer, deeper and more engaged relationships with the place had more comprehensive assessments of changes in the ES; and stakeholders perceptions reflected trade-offs of the local urban conflicts, providing a higher variety and more integrated assessments of impacts than the Environmental Impact Study of the Port expansion. The diversity of forms of knowledge, behaviors and functions, in temporal and spatial scales, proved to be valuable for the groups\' assessments of resource and the territory, and the choice of the analytical categories was fundamental to consolidate the understanding of local socioecological processes. We concluded that the method tested was efficient and respected the intrinsic variability of coastal zones and its function as a socioecological system to assert that EBM has a great potential to improve the effectiveness of EIA. / As externalidades causadas por transformações humanas na estrutura e funcionamento dos ecossistemas têm ameaçado a qualidade ambiental e o bem-estar social em todos os sistemas socioecológicos, incluindo as zonas costeiras.

Presumimos que os stakeholders com relações mais profundas com o local poderiam fornecer avaliações mais abrangentes sobre mudanças na disponibilidade dos principais SE locais, como resultado de maior senso de pertencimento, acesso a diferentes fontes de conhecimento e oportunidades para participar socialmente. Além disso, assumimos que a ABE proporcionaria uma AIA mais robusta, ou seja, com uma perspectiva mais ampla e mais integrada dos impactos na provisão dos SE do que Estudo de Impacto Ambiental da expansão portuária. Realizamos entrevistas em profundidade com quatro grupos diferentes de stakeholders e analisamos o conteúdo por meio de análise de discurso e testes estatísticos para avaliar as ocorrências dos SE no cenário atual (ANOVA de duas vias) e nos cenários de perturbações (ANOVA de medidas repetidas e PERMANOVA), além dos principais padrões de argumentação dos stakeholders. Comparamos esses resultados com o Estudo de Impacto Ambiental da ampliação do Porto para afirmar a robustez do método. Os grupos apresentaram diferentes percepções uns dos outros, o que dependeu do cenário e do SE avaliado. Nós corroboramos as hipóteses: grupos com relações mais próximas, mais profundas e mais comprometidas com o local tiveram avaliações mais abrangentes das mudanças dos SE; e as percepções dos stakeholders refletiram os trade-offs (ou qualidade, aspecto) dos conflitos urbanos locais, proporcionando avaliações mais variadas e integradas de impactos do que o Estudo de Impacto Ambiental da expansão portuária. A diversidade de formas de conhecimento, comportamentos e funções, em escalas temporais e espaciais, se provaram valiosas para avaliações dos grupos sobre os recursos e o território, e a escolha das categorias analíticas foi fundamental para consolidar a compreensão dos processos socioecológicos locais. Concluímos que o método testado foi eficiente e respeitou a variabilidade intrínseca das zonas costeiras e sua função como um sistema socioecológico, o que afirmou que a ABE tem um grande potencial para melhorar a eficácia da AIA.

Gerenciamento costeiro integrado sob uma perspectiva etno-oceanográfica: o conhecimento tradicional na Baía do Araçá / Integrated Coastal Management under an ethno-oceanographic perspective: the traditional knowledge in Araçá BayCaiuá Mani Peres 20 February 2017 (has links)
O conhecimento tradicional (CT) das populações costeiras pode ser fundamental para a Gestão Costeira Integrada (GCI), pois é de base empírica e combina informações sobre o comportamento dos organismos marinhos e sua taxonomia, processos físicos-oceanográficos, métodos tradicionais de manejo dos recursos naturais, etc. O principal objetivo desse trabalho foi compreender o CT de pescadores artesanais da Baía do Araçá e aplica-lo à gestão costeira através de entrevistas semi-estruturadas conjuntamente com a composição de mapas etnográficos e da sistematização das informações adquiridas. As informações etno-oceanográficas levantadas também foram aplicadas a dois modelos conceituais de orientação para o desenvolvimento de estratégias de gestão local, amplamente utilizados na gestão, a análise SWOT e o DPSIR. A Baía do Araçá é palco de conflitos e impactos que comumente influenciam a qualidade das regiões costeiras e suas relações socioambientais, havendo uma forte necessidade de planejamento do uso do território e, assim, servindo como exemplo para outras localidades. Ao todo, 18 pescadores foram identificados como informantes e entrevistados. Todos demonstraram ter afinidade com a Baía do Araçá e atribuíram ao local uma grande importância para a manutenção de seu modo de vida. Na pesca, foi verificado que a utilização de diferentes estratégias e equipamentos varia conforme as condições do mar e do tempo, espécies-alvo, locais de pesca e de acordo com os saberes e habilidades que cada um possui. De modo geral, os pescadores demonstraram ser \"local experts\", possuindo elevado conhecimento do ambiente que utilizam tanto para sobrevivência como para reprodução sociocultural de seu modo de vida caiçara. As análises SWOT e do DPSIR contribuíram para a sistematização do CT levantado, possibilitando sua utilização por gestores e sua aplicação para o planejamento local. Recomenda-se que esse saber e a participação dos pescadores na tomada de decisão sejam considerados na planificação de políticas de gestão dos espaços e recursos naturais costeiro-marinhos. / The traditional knowledge (TK) of coastal populations may be fundamental to Integrated Coastal Management (ICG), as it is based on empirical practices and combines information about the behavior of marine organisms and their taxonomy, physical-oceanographic processes, traditional methods of natural resource management, etc. The major aim of this work was to understand the TK of artisanal fishermen from Araçá Bay and apply it to coastal management through semi-structured interviews along with the composition of ethnographic maps and the systematization of the acquired information. The ethno-oceanographic information obtained was also applied in two conceptual models, widely used in management, that can guideline the development of local management strategies: the SWOT analysis and DPSIR. Araçá Bay has a scene of multiple conflicts and impacts that commonly influence the quality of coastal regions and their socio-environmental relations, outstanding the important need to plan the use of this territory. Thus the study area serve as an example for other localities. In total, 18 fishermen were identified as informants and were interviewed. All of them demonstrated affinity with Araçá Bay and attribute to this place a great importance for the maintenance of their way of life. For fishing, it was verified that the use of different strategies and equipment varies according to the conditions of the sea and of the weather, to the target species, fishing places and according to the knowledge and abilities that each one possesses. In general, fishermen demonstrated to be \"local experts\", possessing an abundant knowledge of the environment that they use for both survival and sociocultural reproduction of their way of life. SWOT and DPSIR analyzes contributed to the systematization of the registered TK, allowing its use by managers and its application for local planning. It is recommended that both the TK and the participation of fishermen in decision-making practices should be considered in policies of management planning for coastal areas and natural resources.

Indigenous practices of pregnant women at the Dilokong Hospital of the Greater Tubatse Municipality in the Limpopo ProvinceMogawane, Mamagoro Anna January 2014 (has links)
Thesis (M.CUR.) -- University of Limpopo, 2014 / Indigenous practices (IPs) are experiences generated by people who are living in a specific region context and a specific cultured group. IPs are shaped by cultural traits that are passed from one generation to the next. The practices are rooted and embedded in such a society and, therefore, the practices become part of the people’s lifestyle. It is difficult to try and change these practices, since people have adhered to them throughout their entire lives. The believe system plays a major role in health care seeking behaviour of individuals because they are informed by the IPs that are observed in their environment (Shaik & Hatcher, 2005).
IPs are stored in people’s memories and are expressed in songs, dances, beliefs, rituals, cultural values, myths, and healing of diseases by using herbs. During pregnancy, IPs are still applied worldwide. Ayaz and Efe (2008) indicate that it occurs mostly in Turkey and Africa where women’s reassurance is depending on the local context and meaning of pregnancy.
THE PURPOSE OF THE STUDY
To determine indigenous practices of pregnant women at the Dilokong Hospital in the Greater Tubatse Municipality of the Limpopo Province.This was achieved by the exploring and describing the indigenous practices of pregnant women in the antenatal (ANC) clinic of the maternity ward at the Dilokong Hospital..
DESIGN AND METHOD
A qualitative, descriptive, explorative and contextual research design was used for the participants to describe the indigenous practices by pregnant women. Data was collected by means of unstructured one-on-one interviews in maternity unit of the ANC clinic at the Dilokong Hospital of the Greater Tubatse Municipality. Ethical considerations as described by Denosa (2000) were adhered to in order to ensure the v
quality of the study. The criteria for trustworthiness were observed as stipulated in Babbie and Mouton (2009).Fifteen pregnant women were interviewed.
FINDINGS AND RECOMMENDATIONS
Four themes with sub-themes emerged from the data analysis by using Tech’ṡ open coding approach (Creswell 2006, Botma, Greef, Mulaudzi & Wright, 2010). Four themes were emerged namely; indigenous practices based on ancestral knowledge; indigenous practices based on spiritual diviners versus church principles; restricted practices versus instructions followed during pregnancy and labour and indigenous practices during labour and delivery. It is recommended that a national IP strategy needs to be developed to provide a framework and platform to support and promote grass roots IPs into mainstream development in the health care system in relation to midwifery practice.
CONCLUSION
The study findings indicated that IPs were regarded as an honourable health intervention by THPs, families, and pregnant women. They showed trust in methods used to preserve pregnancy, labour, and delivery, although, the indigenous practices by pregnant women still continue. Indigenous practices such as cords around their waists, are still observed during physical examinations. However, there is a reduction of prescribed potions mixed with cool drinks for use to accelerate labour and to prevent negative consequences because the potential toxicity has been explained during the provision of health education. These findings call for health care professionals to emphasise training and workshops for the THPs church diviners that are the fundamental principle of effective implementation of IPs to enhance improvement in the prevention of complications during pregnancy, labour and delivery.

Deconstructing ‘Community’ in Community-Based Natural Resource Management (CBNRM): Investigating Traditional Method of Subsistence (TMoS), Traditional Ecological Knowledge (TEK), and Ethnic Diversity for more effective resource management in the Kedougou Region of SenegalStirling, Peter Fraser 30 April 2012 (has links)
This thesis seeks to highlight the importance of a geographic and culturally specific knowledge base to guide natural resource management and governance policy, particularly within the West African context. In order to demonstrate the level of complexity that may exist within this realm, the Kedougou region of Senegal is used as a case study. Traditional Method of Subsistence (TMoS), Traditional Ecological Knowledge (TEK), and ethnic diversity are considered in order to validate the need to go beyond a superficial involvement of community within models such as Community-based Natural Resource Management (CBNRM). Focus groups were conducted for this case study in order to identify areas of similarity and difference that exist along ethnic lines. Two areas of concern that all ethnic groups agreed upon was a depletion of water resources and a diminished growing season that leads to an annual food shortage in the region. Three primary areas of difference were found to coincide with traditional ethnic boundaries in the region: traditional religious belief, wealth accumulation and social hierarchy. The findings of this research demonstrate that while areas of cohesive community concern may serve as a focal point for CBNRM programs, it is also important to consider areas of ethnic difference which hold the potential to significantly influence sustainable and equitable resource management. For example, while traction methods for intensified agriculture are identified as important by all ethnic groups represented in this thesis: (A) traditional agricultural ethnic groups already have experience with these methods, and may only need access to assistance such as micro-credit opportunities, (B) the pastoral ethnic groups already have an abundance of traction animals, and so equipment may be what is primarily needed, while (C) the horticultural group may not have access to the land necessary for optimal traction agriculture. It is therefore suggested that CBNRM programs must be structured around community variables found along cultural lines in order to be of value to government and non-government conservation programs and policy formation in the region.

The Historical Ecology and Social-Ecological Systems of Kona Coast Coral Reefs: towards 'Peopled' Approaches to Marine Science and ManagementShackeroff, Janna M. 23 April 2008 (has links)
<p>No corner of the world's oceans is untouched by humans. Yet in marine science, management, and conservation, oceans are consistently treated as 'unpeopled', that is, human systems are divorced systematically from ecological systems, and assumptions of human/environmental relationships are oversimplified. This dissertation aims to contribute to interdisciplinary, or 'peopled', approaches to marine sciences and management by integrating biophysical and social sciences, specifically historical ecology and resilience thinking on social-ecological systems. Herein, I examine this theoretically (Chapter 2) and empirically by investigating the coral reefs of Hawaii Island's Kona Coast historically, through the oral histories of 'ocean experts', diverse locally-living people from diverse knowledge systems. I investigate human, biophysical, and social-ecological aspects of 'ecological change.' </p><p>Chapter 3 demonstrates that currently there are six expert ocean knowledge systems surrounding Kona's reefs: Native Hawaiians, dive shop operators, tropical aquarium collectors, shoreline fishers, scientists, and conservationists. These are distinct in what experts know about Kona's reefs, and how they know it. The giving and taking of authority between ocean experts, and among people and marine management, influences the condition of the biophysical, social, and management dimensions of Kona's reef systems. </p><p>Chapter 4 examines the biophysical dimensions of change, specifically the historic abundance and distribution of 271 coral reef species. Ocean expert's observations of ecological change are surprisingly consistent, regardless of perspective. Historically, species tend to follow one of eight trends in abundance and distribution, grouping into what I term 'social-ecological guilds'. Analyzing these data with Western scientific frameworks (e.g., trends in apex predators, herbivores, corallivores) proved inappropriate, compared to qualitative approaches. Engaging a multiplicity of perspectives reveals historical ecology broader and richer than from any one knowledge system alone. </p><p>Chapter 5 identifies coupled aspects of marine social-ecological systems, or what I call 'keystone social-ecological features'. I examine 8 features in detail and show how they are central to understanding 'sea change' through such diverse perspectives. Comparing expert's perceptions and responses to ecological through keystone features, I show that 'change' differs based on sociopolitical, economic, etc. perspective. Understanding relationships between and among people, the ecosystem, and marine management institutions is critical for improved ocean management.</p> / Dissertation

Ecological and Ethnoecological Classification of a Forested Landscape in the Tayal Mrqwang Territories, Taiwan (ROC)Berg, Kevan James 23 May 2013 (has links)
In landscape ecology, it is widely acknowledged that landscape is as much a social and cultural entity as it is biophysical, and that people and place must be jointly considered to fully understand the evolution of spatial pattern. This thesis explores the overlapping biophysical and human dimensions of landscape in the context of an (i) ecological and (ii) ethnoecological classification on the local landscape of the Tayal Mrqwang indigenous people in north central Taiwan.
The goal of the ecological classification was to identify ecosystem types for a ~3000 acre landscape by relating vegetation patterns to gradients of physiography, soil, humidity, light, pixel brightness, and human modification across 76 transect sample plots. Using multivariate analyses, seven ecosystem types were identified, ranging from xeric through submesic pine, bamboo, alder, and laurel forests to mesic evergreen broadleaved and mixed coniferous forests. At the broad scale, ecosystems were distributed along gradients of elevation, soil, humidity and human modification, while factors related to local variability in physiography and soil development were more important at the fine scale (i.e., within elevational ecoregions). Within lower elevation sites in particular, patterns of forest variation and soil development were resonant of ancestral practices, including shifting cultivation, terrace farming, arboriculture, and selective extraction.
The objective of the ethnoecological classification was to explore whether the Mrqwang people categorize landscape variation according to systematic or multidimensional knowledge structures. Results of interviews and free-listing exercises revealed an unsystematized classification that recognizes a continuum of forest variation through the intersection of three overlapping categories: history of disturbance, topography and substrate, vegetation. These categories are modified through land tenure and toponyms. The classification appears accommodating of personal experience, and it is theorized that this flexibility results in dynamic knowledge that evolves with time, generating variable characterizations of forest variation rather than formalized categories.
The thesis concludes that despite the lack of formalization, the Tayal are nonetheless highly cognizant of how current forest variation coincides with the environment and the activities of their ancestors. This knowledge represents immense local expertise and must not be excluded from conservation and co-management projects in the local area. / NSERC CGS-D

Indigenous knowledge in participatory mapping of artisanal fishing zones :|ba case study of Angoche district, Nampula Province in Mozambique.Hele, Ernesto Poiosse. January 2007 (has links)
Indigenous knowledge use in identifying artisanal fishing zones is the core issue in this dissertation. It seeks, on one hand, to show the potentially of this knowledge and to establish the relationships between indigenous and scientific knowledge in fishing zones identification and, on other the hand, it is also a trend for alleviating those fishing zones surrounding beaches, estuaries and bays highly exploited by artisanal fishermen. Pushing artisanal fishermen upward offshore and/or into the open sea, they will fish more quality and high economic value fish contributing to enhance their income. By so doing, artisanal fishermen will uplift their living standard and, at the same time, they will contribute to sustainable artisanal fisheries management. Angoche District in Nampula province, north of Mozambique is the study area. The study was carried out to describe the logical sequence underlying on the process of identifying artisanal fishing zones using indigenous knowledge. The relationship between indigenous and scientific knowledge is treated with particular attention. The nature of the study is descriptive and analytical based on qualitative and quantitative data. The method used for data collection was face-to-face interviews using structured and semi-structured open-ended questions. Data on socioeconomic, traditional and cultural practices, technological and climate characteristics were collected, analyzed and discussed. Factors underlying artisanal fishing zones were studied. Spatial and non-spatial information for artisanal fishing zones identification was recorded applying Global Positioning Systems (GPS) and, later, processed and analyzed employing Geographical Information Systems (GIS). Finally, a map showing the localization and distribution of the identified fishing zones in the study area was produced. Results from the research show that identification of fishing zones offshore or open sea can be done simply based on local indigenous knowledge. The GIS technology employment facilitates the inclusion of indigenous knowledge into other knowledge which can be used for local decision making. Sustainable fisheries management can only be achieved by developing a science based on the priorities of local people, and creating a technological base that includes both traditional and modern approaches to problem-solving. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.

The new invasive Odontites serotina: impacts, responses and predictive modelKennedy, Bradley 05 January 2012 (has links)
Invasive alien species (IAS) pose a serious threat to ecosystems and societies worldwide. Local ecological knowledge (LEK) is increasingly valued as a means of understanding environmental issues; however, its application in the context of IAS research has been limited. The overall objective of this study was to document the LEK of farmers and Weed Supervisors to gain insight into a recent IAS, Odontites serotina. I conducted semi-structured interviews with farmers and Weed Supervisors with O. serotina management experience. Results indicated that the socio-economic impacts for farmers were severe in affected rural communities. However, participants had developed promising control techniques, including the application of compost mulch. I used this LEK as well as data on species occurrence, environmental variables, and measures of propagule pressure to forecast the potential distribution of O. serotina across Manitoba. The risk map generated will be useful for guiding future monitoring and public outreach efforts.
