Laboratórios na floresta. Os Baniwa, os peixes e a piscicultura no alto rio Negro / Laboratories in the forest: the Baniwa, the fish and the pisciculture in the Upper Rio Negro

Estorniolo, Milena 07 November 2012 (has links)
O objetivo da pesquisa é refletir a respeito de iniciativas de desenvolvimento sustentável e segurança alimentar entre os povos indígenas na Terra Indígena do Alto Rio Negro, localizada no município de São Gabriel da Cachoeira AM, com foco sobre os projetos de piscicultura entre os Baniwa que habitam as margens do rio Içana e afluentes. Os projetos de piscicultura foram implementados pela Federação das Organizações Indígenas do Rio Negro (FOIRN) e apoiados pelo Instituto Socioambiental (ISA) e, entre os Baniwa, as atividades têm como sede principal a Escola Indígena Baniwa e Coripaco Pamáali. Na escola, técnicos indígenas de piscicultura e alunos em geral participam de treinamentos, oficinas e aulas a respeito de temas como sustentabilidade, manejo do meio ambiente e biodiversidade, e aprendem técnicas de reprodução artificial de peixes em laboratório. A intenção da pesquisa é captar os pontos de vista dos diversos atores envolvidos com esse projeto, de forma a mostrar como técnicos indígenas, lideranças de associações e assessores técnicos não indígenas entendem e negociam entre si a importância e as motivações dos projetos, além das definições dos entes associados a eles como os peixes e o meio ambiente e as maneiras pelas quais se dão as interações entre os conhecimentos indígenas e científicos. Como se procurou evidenciar, para os indígenas envolvidos com os projetos, mais do que a produção de peixes e a resolução de um problema ambiental, o interesse nos projetos estava associado à ampliação das relações e à incorporação e controle dos conhecimentos alheios. / The objective of this research is to reflect upon sustainable development and food safety initiatives among the indigenous peoples in an Upper Rio Negro indigenous land, located in the municipality of São Gabriel da Cachoeira AM (Brazil). The focus is on the pisciculture project executed with the Baniwa that inhabit the riverside and the tributaries of the Içana River. This project was implemented by the Federation of Indigenous Organizations of the Rio Negro (FOIRN, by its name in Portuguese) and supported by the Socio-Environmental Institute (ISA, by its name in Portuguese). Among the Baniwa, the projects main base is the Baniwa and Coripaco Indigenous School Pamáali, where the indigenous pisciculture technicians and students participate in trainings, workshops and classes on topics such as sustainability, environmental management and biodiversity, and learn the techniques of artificial reproduction of fish in laboratory. The intention of this research is to capture the points of view of different actors involved with the project, in order to show how indigenous technicians, leaders of associations and non-indigenous technical advisors understand and negotiate the importance and the motivations of the projects, besides the definitions of the beings associated with them like the fish and the environment and the interactions between indigenous and scientific knowledge. As we sought to evidence, for the indigenous people involved with the project, more than the production of fish and the resolution of an environmental problem, the interest in the projects was associated with the expansion of relations and the incorporation and control of alien knowledges.

Regional Temperature Trends & Variations in the Contiguous United States from 1935 to 1986

Alkolibi, Fahad 01 July 1991 (has links)
The temperature trends and variations of the contiguous United States as a whole and ten designated regions were investigated from 1935 to 1986. To obtain reliable results, 263 stations of the Historical Climate Network (HCN) were used. The HCN stations are corrected for many non-climatic factors which may bias the data. The data for the contiguous United States reveals that the annual, summer, and winter temperatures are free of clear positive or negative trends. Unlike the annual and summer data, winter temperatures exhibit relatively strong variations. Each region was then studyed individually. The summer temperatures for all the ten regions were free of significant trends except Region 2 (Central East Region), which exhibited a significant negative trend. The winter temperatures of the ten regions also lack a statistical significance except for Region 3 (Southeast Region) which shows a significant negative trend. The annual temperatures for the ten regions were also significant except for Regions 2 and 5 (Central East Region and Southern Plains Region). These two regions exhibited significant negative trends. The annual temperature trends for nine of the ten regions were negative while the annual temperatures for the United States as a whole show a positive trend. None of these trends were significant except for Regions 2 and 5. To examine whether or not the differences between the trends of the contiguous United States as a whole and those of the ten regions represents a significant departure from each other, the Expansion Method was used. Applying this method on the annual, summer and winter trends indicated that these differences did not represent a significant departure from those of the contiguous United States. By studying the annual spatial temperature variations of the ten regions it was found that in more than 80% of the years, when the region with the highest positive deviation is in the western United States, the region with the highest negative deviation is in the eastern United States and visa versa.

Mapping the Desertification Process in Southern Morocco Using Remote Sensing Data

Benkhalti, Abdellah 01 July 1987 (has links)
Desertification is a problem occurring in arid and semiarid zones all over the world. It is a consequence of mismanagement of the land. Human activities and livestock pressure on such fragile ecosystems lead to a deterioration of the soil by increasing its salinity, lessening its moisture, and covering it with sand and dust. Aerial photographs and satellite images constitute a tool for mapping and monitoring the desertification process. Multispectral data can assist in detecting the indicators of desertification in early stages in order to plan adequate action. The improvement of the resolution of satellite images and the fact that they are available on a periodic basis make the use of these data suitable for mapping the evolution of desert patches at large scales. The green band of Landsat MSS is used in this study. Two images taken, respectively, in 1976 and 1985 and covering the province of Ouarzazate in southern Morocco are used to map the desertification process and its evolution in the region. At the scale used and given the ground resolution of the MSS (80 meters), significant changes were found between the two images. However, changes occurring at scale smaller than 80 meter square were impossible to detect by visual interpretation of this band.

Where Did They Go? Analysis of Out-Migration from Mammoth Cave National Park, 1920-1940

Eke, Collins U. 01 April 2019 (has links)
The 52,830-acre Mammoth Cave National Park, located in the karst region of south-central Kentucky, was formally established in July of 1941, culminating nearly three decades of park creation that displaced several thousand residents of the region. This thesis sampled residents using the 1920 manuscript census for the United States Census of Population and Housing and tracked their migration destinations using the 1930 and 1940 manuscript censuses. Migration patterns for the entire sample, as well as by race and homeownership status, were identified through mapping. Out-migrants generally chose locations north, west, and east of the proposed park area, noticeably neglecting the Deep South. Statistical analyses proved significant differences between proportions of Black out-migrants and White out-migrants moving to urban areas, as well as those of homeowners and renters who were not successfully tracked during analysis. The research underlines unintended consequences of the forced out-migration from the proposed Mammoth Cave National Park and several factors that contributed to it. In the process, the thesis fills a gap in research on Mammoth Cave National Park and sheds light on an important aspect of Kentucky’s history.

PRODUCING TRADITION: INTERNATIONAL STANDARDS AND DEVELOPMENT IN JORDANIAN OLIVE OIL

Cook, Brittany Eleanor 01 January 2018 (has links)
This dissertation project examines how value is changed and created through organic certification and the universalizing ideas of capacity building within the olive oil industry in Jordan and how these shifts affect the social and material processes of production. I approach organic olive oil production in Jordan as one method that producers use in accessing markets and capacity building. By shifting from looking strictly at organic certified farms to examining the larger context of capacity building and international standards, I identify how organic is just one strategy in a larger effort to diversify Jordanian agricultural production and to access global markets. However, more work needs to be done to elucidate how development shapes organic and other ‘alternative’ initiatives differently than in European and North American contexts. In order to do this, I incorporate postcolonial critiques of GPN and critical development studies to further our understanding how of these certifications and standards are taken up, challenged, and sometimes abandoned in favor of other production methods in local spaces of the Global South. The local embeddedness of olive oil production and the relative recent history of export provide a unique opportunity for examining how producers, organizations, governments, and universities create new export industries. In order to trace how these capacities are built, this dissertation examines the following questions: how is value redefined as producers try to access distant consumers? What are the material and social strategies? In answering these questions, I examine three types of value: taste/sensory, organic/environmental, and gendered tradition. Through the examination of these values, I found that they were each built through a mechanism: re-asetheticizing local taste, creating a new commodity network, and pushing domestic labor into the public sphere. Each mechanism has intended and unintended consequences for the social relations of production. In summary, this dissertation explores the use (and abandonment) of organic certification within the larger context of development and capacity building in Jordan. In order to explore how value is being created in new ways, the three empirical chapters examine extra virginity, organic certification, and women’s rural organizations. By looking beyond a singular commodity chain, this dissertation examines the processes through which institutional assemblages are formed and destabilized. Therefore, each of the three empirical chapters covers a different aspect of the institutions that are defining value within the larger network of the olive industry. This approach will further our understanding of how quality and conventions function in systems under transition. (Higgins, Dibden, and Cocklin 2008a). Together these findings provide a broad picture of efforts in Jordan to improve and expand the Jordanian olive oil industry. A large aspect of this effort is to produce exportable olive oil. While only a small percentage of producers are exporting, governmental and development networks want to build the capacity of the olive industry so that more farmers are producing to international standards. Through this broad initiative, traditional ideas of quality and the best practices of production are being challenged. These shifts create new networks and products through which rural producers try to capture value. While the overall ramifications of this shift for the average farmer are small now, with further government standardizing, production and its associated social relations could be significantly changed. The traditional farmers who were able to sell within their personal networks may lose their ability to sell flexibly, and simultaneously larger irrigated producers may flourish, having larger environmental impacts.

“BEYOND SISTERHOOD THERE IS STILL RACISM, COLONIALISM AND IMPERIALISM!” NEGOTIATING GENDER, ETHNICITY AND POWER IN MADAGASCAR MANGROVE CONSERVATION

Lefèvre, Manon 01 January 2018 (has links)
Understanding women’s experiences of mangrove forest conservation in the Global South is important because mangrove forests are a crucial defense against climate change, and are also increasingly the targets of global climate change policies. The intervention of postcolonial feminist theory combined with feminist political ecology has the potential to bring forward women’s seldom-heard experiences of climate change in these valuable ecosystems. This work supports previous feminist political ecology scholarship focused on understanding women’s complicated relationships to the environment and the gendered effects of climate change policies, while challenging dominant conservation discourse around women as a monolithic group. This thesis focuses on women living in Madagascar’s largest mangrove, particularly under current mangrove reforestation efforts and emerging blue carbon climate change policies. This project explores how the women in this mangrove forest are situated along axes of power differently, the implications of social divisions for conservation, and the ways in which current mangrove conservation projects reproduce power relations in the mangrove by failing to recognize difference.

Pariah, Florida: Helplessness in the Face of Bureaucracy

Fortin, Madeleine 28 March 2002 (has links)
This thesis is a case study of a small agricultural community located along the eastern edge of Everglades National Park, The purpose of this study was to document the way land use decisions have been made and how these decisions have affected this community and the Everglades ecosystem. This research demonstrated that decisions made by the involved agencies have negatively affected both the community of Pariah, Florida and the Everglades ecosystem. Research methods included extensive document research, participant observation and formal and informal interviews. It appears that public concern over “saving the Everglades” has been used to provide a legitimating framework for the achievement of a plurality of personal goals and unstated agency agendas that have little or nothing to do with either the Everglades or the environment in general.

Engineering Colonialism: Race, Class, and the Social History of Flood Control in Guyana

Mullenite, Joshua 22 June 2018 (has links)
Overabundance and scarcity of water are global concerns. Across the world’s low-lying coastal plains, flooding brought on by sea level rise acts as an existential threat for a multitude of people and cultures while in desert (and increasingly non-desert) regions intensifying drought cycles do the same. In the decades to come, how people manage these threats will have important implications not only for individual and cultural survival, but also for questions of justice. Recent research on flooding and flood management probes the histories of survival, and adaptation in flood threatened regions for insights into emergent flood-related crises. However, scholars have thus far overemphasized the technical aspects of how engineered flood control systems functioned, overlooking both the specific social, political, and economic contexts within which past practices emerged and the social worlds that they helped create. This dissertation examines the social, economic, and political histories of flood control projects in the South American country of Guyana in order to understand the long lasting social, political, and environmental impacts of colonial-era projects. To do this, I utilized archival data collected from the National Archives in London, UK, historical newspaper articles collected through online newspaper databases, press release statements from Guyana’s major political parties, and unstructured and semi-structured interviews with residents from coastal Guyana. These data were imported and analyzed using qualitative data analysis software in order to make connections across spatial and temporal scales. The key finding of the dissertation is that, in Guyana, flood control engineering has historically played multiple social, political, and economic roles beyond the functional explanations assumed in many present environmental management discourses. Colonial engineering projects served as a way to protect colonizers from economic crises and social upheaval and were not just a means for protecting the coast from flooding. Additionally, the dissertation found that these projects were key to creating the racial geographies that helped to protect colonialism in its final years and which continue to shape coastal life today. Finally, the dissertation found that, after the end of colonialism, flood engineering projects were incorporated into larger projects of racialized regime survival.

Risk Perception and Beliefs about Volcanic Hazards: A Comparative Study of Puna District Residents

Leathers, Melanie Marie 25 August 2014 (has links)
The purpose of this research is to better understand how residents of communities located on the flanks of Kilauea, Hawai'i view the hazards associated with volcanic events taking into account hazard proximity, cultural beliefs, municipal trust, and evacuation planning. The study was conducted in the lower Puna district, an area with a rapidly growing population but limited infrastructure. Data were collected though a questionnaire survey undertaken at venues throughout the district, including grocery markets, bakeries, farmers markets, the public pool, and other gathering places. Overall, the results indicated that people understand the natural hazards of the place but are generally not concerned about the potential impacts of these hazards on their livelihoods; few could determine whether or not they lived in a lava zone, the impacts on health, and the need for evacuation planning. Cultural considerations appear to play major role and many residents believe that Madam Pele, Goddess of Fire, has a stake in the events of Kilauea. Both hazard understanding and cultural belief systems varied by gender, age, income, and education. When compared to findings from earlier studies within the lower Puna district, it was noted that opinions have shifted over time and that belief in Pele had strengthened. This study demonstrated that understanding the opinions and patterns of belief within communities must be ongoing and municipal planning must be altered over time to accommodate evolving needs and beliefs of a community to obtain optimum community support.

Industrial Pollution and Economic Compensation : <em>A  Study of Down Stream Villages in Noyyal River, Tirupur, Tamil Nadu, South India</em>

Santhi Kanna, Dorai Kannan January 2008 (has links)
<p>Tirupur is an Indian textile town which constitutes many dyeing and bleaching units situated in the upstream. Tirupur serves as one of the major exporters of textiles. The industrial pollution have affected not only the surface water but also the soils and ground water. This thesis studies the impacts of industrial pollution on agriculture and livestock. It also explores the implicated problems involved in putting an economic compensation mechanism into practise. The impact study was made on the detailed primary data collected from an intensive study of comparing a pollution affected villages located downstream of the Orathapalyam dam, Tamil Nadu, South India with a control village. The cost estimates that the impact of industrial pollution on predominant crops is quite substantial in monetary terms. This paper argues that the compensation principle might work if the assessment is done to all affected victims. Both quantifying and non quantifying benefits should be incurred in the mechanism. Further, mere passing of fines and creating institutional structures are not sufficient to address the environmental problems. Policies should be implemented in their right perspective. Institutions should be strong enough, with more autonomy and powers, to deal with problems and to monitor the RO plants in dyeing units in Tirupur.</p>
