This study describes the results of a cross-sectional survey conducted in Mambwe district in the Eastern Province in Zambia. It uses a One Health approach to assess the impact of veterinary, medical, environmental and social determinants on animal and human health and wellbeing. One Health is defined as a holistic and interdisciplinary approach that describes the complexities between people, animals, the environment and their health. Human wellbeing is defined in this thesis as 'a condition in which all members of society are able to determine and meet their needs and have a large range of choices to meet their potential' (Prescott-Allen, 2001). As a first step, eight focus group discussions with the inhabitants followed by key informant interviews with stakeholders in the area were conducted to give a primary impression and narrow down the problems in relation to animal and human health of the area in general. Following this, a randomized selection of 210 households was visited and in each household blood samples were taken from all humans and all animals belonging to five animal species, namely cattle, goats, sheep, pigs and dogs. A third of the households did not keep any of the animal species chosen for sampling, but their inclusion was important for the social analysis. In all of these 210 households a wellbeing questionnaire was administered and, for every human and animal sampled, a health questionnaire. The study area falls within the tsetse-infested region of Zambia. It has a high wildlife density reflecting the proximity of several national parks and is historically endemic for both human and animal African trypanosomiasis (HAT&AAT). Therefore humans and animals were tested for trypanosomiasis using internal transcribed spacer (ITS) polymerase chain reaction (PCR). Since it is important as a differential diagnosis, malaria was tested for by a rapid diagnostic test in the field from human blood. Sera from mature individuals from all animal species except pigs were tested in a field laboratory for brucellosis using the Rose Bengal test. Additionally, cattle and dogs were tested for five genera of tick-borne infections (TBI) including Anaplasma, Ehrlichia, Theileria, Babesia and Rickettsia using reverse line blot (RLB) in the laboratory at the University of Edinburgh (UoE). The blood samples for PCR and RLB analysis at UoE were stored on WhatmanTM FTA cards. A total of 1012 human samples were tested for HAT and none found positive. 1005 (seven people had been tested positive or treated against malaria shortly before the sampling) people tested for malaria showed an overall prevalence of 15% (95% CI 13.2-17.7). None of the 734 Rose Bengal tests showed up positive for brucellosis. The prevalence of AAT in 1275 samples tested was much lower compared to former samplings; in cattle 22% (95% CI 18-27.2), in goats 7% (95% CI 4.5-9.2), in pigs 6% (95% CI 3.2-9.4), in dogs 9% (95% CI 5.2-13.6) and no samples were found positive in sheep. The prevalence of TBIs is much more complex with many multiple infections. A total of 340 cattle and 195 dogs were tested. In cattle the number of samples positive for any microorganism was as follows; 92% (95% CI 88- 94.2). Overall there were fewer positive samples from dogs with 25% of animals infected (95% CI 19.2-31.8). The wellbeing and health questionnaires were designed to help to identify possible risk factors for the above-mentioned diseases and signs, such as fever, diarrhoea and seizures, indicative for several other diseases. The results of these surveys might also help to identify potential reasons for a lower or higher prevalence of trypanosomiasis and malaria found than expected from previous studies. Additionally, information on personal happiness, attitudes towards veterinary and medical services, medical treatments received, education, women's reproductive history, drug abuse, people's perceptions of changes in environment and agriculture, demography, poverty and migration were collected via the questionnaires alongside information on livestock demographics and fertility. One of the main conclusions is that both medical and veterinary health care systems suffer from a number of shortcomings. The distance to appropriate treatment and care facilities is far and the necessary drugs are often unavailable. Also, both the knowledge and technology for diagnosing selected diseases is not in place. This study suggests that neurocysticercosis (NCC) plays an important role in this area due to the high number of seizures reported in people, in whom treatment for epilepsy was unsuccessful. Samples taken from a few pigs indicated the presence of Taenia solium, the causal agent of NCC. Furthermore, many of the TBIs are of zoonotic nature and further investigations must be made to begin to assess the burden of these diseases in humans and animals. Environmental changes such as degradation of the vegetation are likely to have an influence on the prevalence of studied diseases and this aspect is being investigated further in other studies. Due to the nature of a cross-sectional study, only limited conclusions can be drawn on the causal relationships of disease prevalence, but the social analysis conducted in this study confirmed the interactions of selected factors related to health and wealth unique for this study area.

Gorongosa: a history of an African landscape, 1921-2014, focuses on changes in the Gorongosa ecosystem, in central Mozambique, southeastern Africa. Environmental changes result from natural, non-human causes and from the activities of humans. I describe four socioecological events: African and Portuguese interactions, Gorongosa National Park, the effects of Mozambique’s civil war, and the Park's restoration in the aftermath of the civil war. Prior to European partition of Africa in 1884-85, Mozambique did not exist as clearly a demarcated territory as it is now. Today, the sense of Mozambicanhood bears traces of Portuguese colonial era experience. The demarcation of Mozambique’s boundaries and the reshaping of the colony until 1975 was a painful process that both the Africans and Portuguese colonialists endured; these physical and social separations from the rest of southern Africa represented the first human-induced changes in southern Africa. The endeavors to reshape Mozambique did not end with political boundaries. Painful processes, including the reshaping of Gorongosa National Park in the Gorongosa ecosystem, continued after border demarcations. Countless Mozambican and Portuguese lives were lost in the long trajectory within the colony as the Africans and the Europeans all developed a sense of unity in diversity while reshaping their attitude of and about Mozambique. After independence in 1975, internal transformations and wars continued reshaping Mozambique and Mozambicans, as different nationalists sought to maintain their colonial experience. These dynamics marked the environmental history of the Mozambican and Portuguese peoples and are often reflected in the prevalence of high sympathy, which the two peoples share toward one another. Gorongosa: a history of an African landscape, 1921-2014, critically celebrates these collective achievements.

Natural and human-induced environmental changes have been altering the earth's surface and hydrological processes, and thus directly contribute to the severity of flood hazards. To understand these changes and their impacts, this research developed a GISbased hydrological and hydraulic modeling system, which incorporates state-of-the-art remote sensing data to simulate flood under various scenarios. The conceptual framework and technical issues of incorporating multi-scale remote sensing data have been addressed. This research develops an object-oriented hydrological modeling framework. Compared with traditional lumped or cell-based distributed hydrological modeling frameworks, the object-oriented framework allows basic spatial hydrologic units to have various size and irregular shape. This framework is capable of assimilating various GIS and remotely-sensed data with different spatial resolutions. It ensures the computational efficiency, while preserving sufficient spatial details of input data and model outputs. Sensitivity analysis and comparison of high resolution LIDAR DEM with traditional USGS 30m resolution DEM suggests that the use of LIDAR DEMs can greatly reduce uncertainty in calibration of flow parameters in the hydrologic model and hence increase the reliability of modeling results. In addition, subtle topographic features and hydrologic objects like surface depressions and detention basins can be extracted from the high resolution LiDAR DEMs. An innovative algorithm has been developed to efficiently delineate surface depressions and detention basins from LiDAR DEMs. Using a time series of Landsat images, a retrospective analysis of surface imperviousness has been conducted to assess the hydrologic impact of urbanization. The analysis reveals that with rapid urbanization the impervious surface has been increased from 10.1% to 38.4% for the case study area during 1974 - 2002. As a result, the peak flow for a 100-year flood event has increased by 20% and the floodplain extent has expanded by about 21.6%. The quantitative analysis suggests that the large regional detentions basins have effectively offset the adverse effect of increased impervious surface during the urbanization process. Based on the simulation and scenario analyses of land subsidence and potential climate changes, some planning measures and policy implications have been derived for guiding smart urban growth and sustainable resource development and management to minimize flood hazards.

Lakes and lake sediments from four areas around the Antarctic Peninsula are described. The concentrations of trace metals in sediment are found to be a useful tool in distinguishing between the different sedimentary phases during a transition from marine to limnic environment. A tephrochronology based on Deception Island tephra is developed, and used to cross date sediments from different lakes in order to overcome the radiocarbon dating problem of the area. The fluctuating concentrations of copper and phosphorus from penguin guano in the sediment of Lake Boeckella are used as a proxy for the penguin inpact on the sediment, and the size of the penguin rookery on the shores of the lake. Anthropogenic activities in the area, as well as climatic changes are discussed in relation to the rookery size. A radiocarbon dating model developed for the sediment of Lake Boeckella showed that the radiocarbon correction factor in the sediment depends on the amount and apparent age of the penguin guano washed down into the lake, and the amount of particulate carbon from the watershed present in the sediment. Neither the "old" meltwater from the glaciers nor dissolved carbonates contributes significantly to the correction factor. The model is used to achieve more accurate radiocarbon dates of the Lake Boeckella sediment. This model, or a modified version, may contribute to a higher dating accuracy and a better understanding of the dating problems in Antarctica. Deglaciation dates, as well as data on the climatic and environmental history of Byers Peninsula on Livingston Island, South Shetland Islands, of Hope Bay, Antarctic Peninsula and of Hidden Lake area, James Ross Island are given. / <p>Diss.

Much of the discourse on cultural change has been descriptive and explanatory, with few attempts to be predictive. Where indicators of and buffers to change are identified, they tend only to be post-event assessable. The need for a tool with strong predictive power is fundamental to cultural (and environmental) impact assessment and the rationale behind this developmental work. Focusing on traditional cultures and their environmental context, and based on a case study of the Juatinga Ecological Reserve, Brasil, this research advances knowledge on modelling cultural and environmental changes, and how to manage these changes for accepted goals. A heuristic tool is presented for assessing the impacts of pressures on a culture and its related environment as well as the efficacy of management responses. This tool is associated with methods to assist in developing predictive models representing the change processes. The change model building process involves consulting stakeholders as a way of integrating different perceptions, to identify pressures, responses and links associated with cultural and environmental change. This assists in creating a co-learning environment, which facilitates communication between stakeholders. The change modelling approach permits incorporation of the complexity and uncertainty of the system represented, and enables scenario analyses. These allow expected local and flow-on impacts of management interventions to be tested. This approach is more efficient than stand-alone performance indicators that do not allow for the synergic impacts of management interventions to be observed and assessed. Using the models representing the cultural and environmental change processes of the Caiçaras of the Juatinga Ecological Reserve, this research identifies that tourism is a major pressure for change (at that locality). This study also identified that tourist numbers at new and small tourism destinations, as well as on a continental scale, can be forecast using exponential and polynomial functions. Yet, tourism flow may be perturbed at any given time by, for example, acts of violence and when the type of marketing changes. In addition, tourist numbers cannot be greater than the total population, therefore it cannot grow indefinitely as exponential and polynomial functions suggest. Hence, the use of exponential and polynomial functions to forecast tourist numbers is more reliable for short periods, such as four or five years, and when based on six or more sets of data points. The greatest contribution of this research to the cultural change discourse is its innovative approach to study, forecast and manage cultural and environmental changes. The continuation of this research may lead to identifying general theories relating pressures and responses to indicators of cultural and environmental changes.

O objetivo desse trabalho é o ordenamento territorial em área de proteção ambiental, analisando o processo de ocupação a partir da ação de promotores imobiliários numa área natural protegida por lei. Nos últimos 20 anos, observamos o crescimento irregular e desordenado de empreendimentos imobiliários, dinamizado pelo turismo. A procura por locações para veraneio provocou rápida expansão de loteamentos habitacionais e estabelecimentos comerciais sobre longa faixa de restinga, entre 26 km de praia e complexo sistema lagunar, localizada nos municípios de Saquarema, Araruama e Arraial do Cabo, Estado do Rio de Janeiro. Essa ocupação ameaça ecossistemas remanescentes como: brejos, lagoas costeiras, manguezais e restingas que deveriam ser preservados segundo leis ambientais. Nesse universo, responderemos as seguintes questões: Como atuam os agentes sociais presentes no conflito? Qual o papel do Estado nesse processo? As leis que regem as políticas de conservação ambiental são interdependentes? Há conflitos de competências? A coleta de informações ocorreu através de análise documental, de imagens de satélite, trabalhos de campo, visitas técnicas e entrevistas com agentes sociais. Os resultados possibilitaram um mapeamento da ação desses agentes na área em estudo, suas competências e geração de mapa de uso do solo. / The territorial area of environmental protection, analyzing the process of occupation from the action of developers in a natural area protected by law. Over the past 20 years, we observed irregular and disordered growth of property developments, spurred by tourism. The search for locations for summer caused rapid expansion of housing developments and shopping on long stretch of sandbank, between 26 kilometers of beach and lagoon system complex, located in the municipalities of Saquarema, Araruama and Arraial Cape, State of Rio de Janeiro. This occupation threatens remaining ecosystems such as wetlands, coastal lagoons, mangroves and salt marshes that should be preserved seconds environmental laws. In this universe, we answer the following questions: How social work officers present in the conflict? What is the role of the state in this process? The laws governing environmental conservation policies are interdependent? There are conflicts of competence? Data collection occurred through documentary analysis of satellite images, field work, technical visits and interviews with social workers. The results allowed a mapping of action of these agents in the study area, their skills and generation of land use map

Among the communities usually inhabiting recently created reservoirs, benthic macroinvertebrates have special relevance for having close relationship with environmental factors, simultaneously and differently responding to environmental changes. Therefore, based on the hypothesis that the structure and composition of benthic community might be altered as a consequence of the river damming, the presente work had as its main objective to make a species inventory occurring in a stretch of the Madeira River, before and after the construction of the UHE de Santo Antônio do Madeira, determining the composition and spatial di stribution of Hirudinea assemblages, verifying if the Oligochaeta species associatins in Madeira River are similar to those found in other large South America rivers, and if the construction of the power plant altered the patterns of association and distribution of species. Besides that Chironomidae assemblages were analyzed aiming to see if they were also affected, looking at their responses evaluated by biological indices considering the environmental changes after river damming. For this, sediment samples were collected for benthic macroinvertebrates analyses in eight sampling points, being six located upstream the dam and two downstream, before and after damming. Water variables were in situ measured: pH, electrical conductivity, dissolved oxygen, turbidity and temperature, and the sediment collected for granulometric analyses and nutrient concentrations measurements. The results obtained showed that both, water variables and sediment size-fractions were altered in some localities influencing leeches assemblage composition and abundances. It was also observed that Oligochaeta assemblage had a pattern of species association and that it does not tend to disappear after the river damming. However, the river damming caused changes in the structure and composition of the populations of Chironomidae. A decrease in the richness of taxa and overall changes in the benthic community before and after damming was also observed, thus evidencing that dam construction acted as a controlling factor of benthic community. Although the taxonomic richness and diversity index have not responded to these changes, contrarily the β diversity and the relationship between diversity and abundance of classes were sensitive to changes caused by the damming. / A construção de usinas hidrelétricas em sistemas lóticos promove alterações nas características morfológicas e funcionais destes ecossistemas, levando a mudanças na dinâmica funcional e estrutural das comunidades biológicas de forma qualitativa e quantitativa. Dentre as comunidades que se desenvolvem nos reservatórios recém-criados, a comunidade bentônica tem especial relevância, por apresentar estreita relação com os fatores ambientais, respondendo simultaneamente e diferentemente às variações do ambiente. Por isso, baseados na hipótese de que a estrutura e a composição da comunidade bentônica poderá sofrer alterações em consequência do represamento de um rio, este trabalho teve como objetivos realizar um inventário das espécies com ocorrência em um trecho do rio Madeira antes e após a construção da UHE de Santo Antônio do Madeira, observar composição e distribuição espacial das populações de hirudíneos, verificar se as associações entre as espécies de Oligochaeta do rio Madeira são semelhantes às registradas nos grandes rios sulamericanos e se a construção desta hidrelétrica alterou o padrão de associação e distribuição das espécies, além de identificar como a assembleia de Chironomidae pode ser afetada pela construção da barragem por meio das respostas avaliadas por índices biológicos frente às mudanças ambientais após o represamento do rio. Para isso foram coletadas amostras do sedimento, para a análise da fauna, em oitos pontos, sendo seis na montante e dois na jusante da barragem, antes e após a sua construção, sendo medidas in situ as variáveis da água: pH, condutividade elétrica, oxigênio dissolvido, turbidez e temperatura, e coletado sedimento para a análise granulométrica e concentrações de nutrientes. Os resultados mostraram que tanto as variáveis da água quanto a composição granulométrica do sedimento foram alteradas em algumas localidades influenciando na distribuição e abundância das assembleias de hirudíneos. Foi observado que as assembleias de Oligochaeta possuem um padrão de associação entre as espécies e que este padrão não tende a desaparecer após o barramento do rio. Porém o barramento do rio provocou alterações na estrutura e composição das populações de Chironomidae. Também foi observada uma redução na riqueza taxonômica entre o pré e pós–barramento e mudanças na comunidade bentônica, evidenciando que a construção da barragem atuou como um fator controlador da comunidade bentônica. Embora, a riqueza taxonômica e o índice de diversidade não tenham respondido a estas mudanças, contrariamente, a diversidade β e a relação entre a diversidade e as classes de abundância foram sensíveis às alterações provocadas pelo represamento.

Orientador: José Eduardo Zaine / Banca: José Cândido Stevaux / Banca: Antonio Roberto Saad / Resumo: A pesquisa tem como tema central o reconhecimento de áreas modificadas pela atividade de mineração como uma unidade geológico-geotécnica no Município de Estiva Gerbi (SP). As últimas décadas têm sido marcadas por grandes mudanças tecnológicas, pelo aumento da população e o decorrente aumento das cidades, tendo como reflexo a conseqüente elevação do consumo dos recursos naturais. Este estudo caracterizou cavas e pilhas de botafora, geradas pela atividade extração de argila para a indústria cerâmica, como modificadoras das características geológico-geotécnicas naturais dos terrenos. Para atingir o objetivo deste estudo foi realizado um mapeamento do Município de Estiva Gerbi onde a área de estudo foi dividida em 6 unidades geológico-geotécnicas: Unidade I - solos areno-argilosos, em relevo de média vertente da Formação Aquidauana; Unidade II - solos argilosos, em situação de baixa vertente da Formação Aquidauana; Unidade III - solo coluvionar, em situação de meia encosta de cobertura cenozóica indiferenciada; Unidade IV - solo residual, de topo de colinas amplas de cobertura cenozóica indiferenciada; Unidade V - solo aluvionar, de planície de inundação, e Unidade VI - áreas modificadas, onde foram agrupadas as áreas oriundas da atividade de mineração, individualizadas como uma unidade geológico-geotécnica específica. A pesquisa comprovou que as cavas e pilhas de bota-fora e sua área de influência possuem características particulares em relação às outras unidades. Através de observações de campo conclui-se que as principais alterações ambientais desta unidade são: a mudança no perfil de solo, a declividade do terreno, alterações no nível de água subterrâneo, a formação de lagos, as condições de permeabilidade, a aceleração de processos erosivos e a disposição de lixo...(Resumo completo, clicar acesso eletrônico abaixo). / Abstract: The research main issue is the recognition of areas modified by mining activity as a geological-geotechnical unit in the Municipality of Estiva Gerbi (State of São Paulo). The last decades have been marked by great technological changes, population boost and the resulting enlargement of cities caused the elevation of natural resources consume. This study characterized furrows and putting out piles, generated by the activity of clay extraction to the ceramic industry as modifiers of geological-geotechnical natural aspects of the soil. To achieve the aim of this study, the Municipality of Estiva Gerbi was mapped and the study area was divided in 6 geological geotechnical units. Unit I sand-clay soils on a mid hogback relief of "Aquidauana Formation"; Unit II - clay soils, on a low hogback situation of "Aquidauana Formation"; Unit III - adjacent to river soil on a mid cliff of surface finish; Unit IV - residual soil, on the top of wide hills with Cenozoic undistinguished surface finish; Unit V - river soil, on flooding plains and Unit VI - modified areas, where the areas deriving from mining activity where grouped, individualized as a specific geological-geotechnical unit. The researched proved that furrows and putting out piles and its influence area has particular characteristics comparing to other units. Through field observations, it was concluded that the main environmental alterations of this unit are: the modification of the soil profile, the declivity of the terrain, subterranean water level alterations, the formation of lakes, the conditions of permeability, the acceleration of erosive processes and the disposal of refuse. According to specific literature about technogenical deposits, the putting out piles are classified as a built layer of spolic type. / Mestre
