Повний текст джерелаSeveral problems such as spatial inequalities between regions and spatial segregation within cities arise from households’ location choices. The purpose of this dissertation is to address these problems with theoretical and experimental studies. To begin, a laboratory experiment has been conducted in order to understand under which conditions different urban structures emerge. Indeed, in the U.S., spatial segregation occurs and the richer households are located in the suburbs while the poor ones are located downtown. The opposite pattern is observed in several major European cities. It appears in our study that the ratio ‘transportation costs/demand for land’ is a key factor for explaining these two types of segregation. Then, a theoretical model is used to reproduce several types of urban structures, where poor and rich households are located in the same neighborhoods. The theory predicts that policy interventions can lead to very different outcome. Then, the spatial distribution of human capital among regions is studied. Because skilled workers are mainly attracted toward wealthier regions, economic growth is lower in the poorer regions and spatial inequalities increase. The theoretical model predicts that it is possible to bring back the skilled workers in poor regions because there exists complementarities between skilled and unskilled workers. Indeed, the presence of unskilled workers enhances skilled workers' productivity, making their return more profitable. To finish, a laboratory experiment has been conducted to study consumers' behavior. Because in New Economic Geography models, the existence of a representative consumer is often assumed. The relevance of this hypothesis is tested. It appears that the existing models do not take enough into account heterogeneity in tastes among the consumers

Повний текст джерелаAirports are protean geographical objects characterized by their « accelerated obsolescence » (BANHAM, 1962). Since the 1990s, their final transformation has been structured around a process of functional diversification engendered by new activities, which are sometimes very different from air transport, in order to increase the infrastructures’ profits and profitability in a context of widespread privatization. The world’s largest hub airports are concerned by this evolution, especially the Paris-Charles-de-Gaulle airport, the world’s fourth busiest airport by international passenger traffic. This trend, which has given birth to the operational concept of airport city, as the Anglo-Saxon operators and observers call it, stirs up the geographical curiosity in two ways. Firstly, it questions the primary function of airports, which become unidentified spatial objects that need to be redefined. Secondly, the concept of airport city questions the city itself. Indeed, what makes a city a city on a material (urbanity) and conceptual (“citadinity”) level? Can a space with urban functions be considered as a city? Is the airport city only a functional city? By assessing the geographical relevance of the concept of airport city, this thesis aims at making the concepts of urbanity and “citadinity” operational concepts, so as to compare them with the airport ground. By adjusting the observation scale to the whole airport area, it also replaces the airport at the centre of the geographical study. Thus, the airport is not simply viewed as a terminal. Finally, this thesis aims at understanding the whole airport society’s spatiality (passengers, employees, accompanying people, homeless people…) by assessing the concept of “citadinity"

Повний текст джерелаThis doctoral dissertation is about exploring and developing procedures making it possible to incorporate spatial analytical tools, and more concretely Geographic Information Systems (GIS), into one of the most interesting approaches to study sustainability issues: the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM). In particular, this is a methodological exercise having the goal to develop, test and propose tools that can be used for the integrated assessment of the sustainability of socio-ecological systems, and more specifically rural systems. Therefore, this thesis combines both theoretical discussions and practical case studies. The development of a robust methodology required dealing with the theory of complexity, whereas the test and calibration of the resulting methods required ground-based with empirical work. Thus, the dissertation goes through three main parts: an introductory part developing the theory, a second part with the three case studies and a third part with the conclusive reflections on the lessons learned about the methodology. The first part is divided in three chapters where I firstly make a general introduction to the context motivating this thesis, a second chapter in which I explain the MuSIASEM approach, the background theories and I justify why I have chosen this approach rather than others, and a third chapter where I develop the general theory and methodology to analyse rural systems tested in the second part. The second part of this dissertation contains the core of the applied research; the three case studies. The first application is a case study of rural Laos, where I develop a system of accounting capable of handling the quantitative information about the metabolic performance of typologies of farming systems across levels and scales based in the land use and GIS information. This quantitative method can scale-up and scale-down the characterization of elements defined on different hierarchical levels of organization, which can only be perceived and represented on non-equivalent descriptive domains. The second case study was undertaken in Guatemala and it included empirical field work. There, I established a procedure to generate geographic information at local level to be used for the metabolic analysis of the system, in order to later simulate scenarios taking into account geographic constraints. The third case study is more complex, it is an analysis of Mauritius Island integrating many dimensions and scales (energy, food, water, money, land use, human activity) and handling data through the use of GIS and remote sensing to simulate possible scenarios of development. The final part of the dissertation develops some reflections about the particular scope of this thesis (the use of GIS in MuSIASEM), and a last chapter of concluding theoretical remarks.

Повний текст джерелаIn this thesis I investigate theoretically and empirically the evolution of population and income levels across the world. In the first chapter, titled "The Globe as a Network," I ask: how important are falling transport costs for patterns of population and income growth since 1000 CE? To answer this question, I build a quantitative dynamic spatial model with an agricultural and a non-agricultural sector, and endogenous fertility, migration, innovation and technology diffusion. In this model there exists an endogenous threshold for global transport costs, which is characterized by a simple network statistic. If transport costs are above this threshold, the world converges to a Malthusian steady state. If transport costs fall below this threshold, the world economy enters a process of sustained growth in population and income per capita. Taking this model to the data, I divide the globe into 2,249 3 degree by 3 degree quadrangles. I assign each location an agricultural potential determined by exogenous climate and soil characteristics. I infer bilateral transport costs by calculating the cheapest route between each pair of locations given the natural placement of rivers, oceans and mountains. I calibrate the model so that in the year 1000 the world is in a Malthusian steady state. I then drop the cost of water and land transport exogenously in a way that is consistent with historical evidence and track the endogenous evolution of population and income until the year 2000. Qualitatively, this exercise generates slow but accelerating growth in both population and income per capita for the first 800 years, an abrupt takeoff in growth after 1800 CE with Europe in the lead, and a large increase in the dispersion of income per capita after 1800 CE. Quantitatively, the model accounts for 55% of the variation in population density across 10 major regions in 1000 CE, 44% of the variation in income per capita across regions in 1800 CE, and is able to generate 43% of the overall dispersion in income per capita in 2000 CE. The second chapter is titled "The Demographic Transition Across Time and Space." The demographic transition, i.e., the move from a regime of high fertility/high mortality into a regime of low fertility/low mortality, is a process that almost every country on Earth has undergone or is undergoing. Are all demographic transitions equal? Have they changed in speed and shape over time? And, how do they relate to economic development? I seek to answer these questions by putting together a data set of birth and death rates for 188 countries that spans more than 250 years. Then, by estimating start dates and end dates for the transitions of the countries in our sample, I document 3 new facts. I find, first, that the average speed of transitions has increased steadily over time. Second, I document that income per capita at the start of these transitions is more or less constant over time. Third, we uncover evidence of demographic contagion the entry of a country into the demographic transition is strongly associated with its geographic and linguistic neighbors having already entered into the transition even after controlling for other observables. In my third chapter "The Diffusion of Demography: A Quantitative Exploration," I build a transparent model of the demographic transition in the tradition of Barro, Becker, and Lucas with multiple countries. In addition to the standard quantity-quality trade-off between how many children to have and how much to educate them, there is also technology diffusion between locations. As a quantitative exercise, we introduce a skill-biased technological change that diffuses away from Britain to the rest of the world. Despite its simplicity, the model is quite successful in matching observed patterns of the demographic transition across the globe, both in terms of timing and geographical location.

Повний текст джерелаEsta tesis parte del estudio de un grupo de especies de escarabajos acuáticos (Agabus brunneus complex) que poseen diferencias importantes en el tamaño de sus rangos geográficos, contando con una especie insular (A. rufulus), una continental de rango restringido (A. ramblae) y una continental de rango amplio (A. brunneus) para estudiar los factores implicados en esas diferencias. Este complejo de especies diversificó a finales del Pleistoceno en la península ibérica posiblemente tras la colonización de A. ramblae desde Marruecos. Una de las especies resultantes A. brunneus en algún momento de la diversificación desarrolló la capacidad de resistencia a bajas temperaturas lo que le facilitó el poder extender su rango hacia climas más fríos. Se empleó la proteómica de poblaciones para analizar la respuesta de varias poblaciones de A. brunneus y A. ramblae frente a temperaturas que pueden experimentar en la naturaleza. Al estudiar la variabilidad a distintos niveles entre dos poblaciones naturales de A. ramblae obtuvimos una buena reproducibilidad de nuestros experimentos. Al analizar de forma global dos poblaciones para cada especie (Marruecos y península ibérica para ambas) descubrimos que la diversificación de la filogenia ha ido acompañada de cambios en la respuesta a nivel de expresión proteínica. La mayoría de las proteínas identificadas están relacionadas con el metabolismo energético y con proteínas del estrés, estas últimas se expresan diferencialmente entre las dos especies analizadas, indicando una diferente respuesta al estrés térmico. El presente trabajo abre la posibilidad de realizar este tipo de experimentos empleando poblaciones naturales de especies no modelo y demuestra que la respuesta frente al estrés de un factor ambiental, en este caso la temperatura, puede recuperarse empleando para ello la proteómica. Así mismo las diferencias en el tamaño del rango pueden ir acompañadas de la adquisición de distinta capacidad de respuesta frente al estrés térmico.

Повний текст джерелаThis paper presents an explanation to the problems found in the teaching-learning process of Geography in São Paulo city`s schools. The bibliographical research included the educational production on the Reforms suggested by country system, the production on the pedagogical and course propasals suggested by the São Paulo states teaching system; and the production, so-called classical to the Brazilian Geography, regarding the institution period of its teaching in São Paulo state ending of the XIX Century and alapsing of the XX Century. This analyses plus the surveys carried out with the teachers (questionnaires and open interviews 1999/2000), made possible an interpretation to the problems found on this school subject teaching. Theanalyses made about the Reforms base documents, indicated a worrying limitation on the didactic questions, leading to the need of depth regarding the teaching institution in São Paulo state, reference acquired by reading the classics on Geography. The precursory organization experienced by the paulista system of teaching resulting from the needs imposed by the economical development, concentrated mainly on the necessary conditions for this process (didactics experiments, adoption of modern methods of teaching, course proposals accomplishment). This displacement to the state system demonstrated that the measures taken for its organization would have excessively contributed and influenced the proposals suggested by the country system. Demonstrated also the reflexes of the political collisions engaged by professors which positions were opposing. The research carried out about the Geography teacher`s formation and performance in São Paulo city (primary and high school systems) has permitted to recognize and understand their practice as the organization history reflex of both state and national teaching system. The bibliographical analyses doing and the survey carried out with the teachers, demonstrated that, airsing from the pedagogical knowledge, the problems result from the nondirect entailment between the teaching system and the Brazilian reality. And concerning the Geography knowledge, the foud problems result from the lack of researches about the possible relation between the didactic knowledge and the utilization of technical tools gathered by the area. The information arisen from the teachers, proved the lack of concerning on the didactic knowledge with the suggested proposals by the official offices, but, demonstrated also a peculiarity, that part of these teacher chow they are concerned about didactic knowledge. This peculiarity signals a possible answer to the problems found on Geography teaching-learning process, indicating also the urgency of reflection based on didactic questions and not only on the school system pedagogical ones

Повний текст джерелаIn first part of this work consists on the installation of pluviographic, water-height graphs and surveying of hydrological events with obtained data from spatial distribution of precipitation observed and resultant hydrograms. Experiments of water infiltration in the soil were done by an infiltrometer disc to characterize the spatial variability of hydraulic conductivity and the losses of infiltration in the basin obtaining two sets of data that showed to be lognormally distributed in average equal to 15.8 mm/h and 5.47 mm/h. A theoric study was conduced in the second part of work comprehending the development of hydrologic model distributed. The conception of the model proceed from the premise that allbasin area can be represented by cells derived from a Digital Terrain Model (DTM) specifying in each cell the hydraulic equation - hydrologic. The soil heterogeneity and the precipitation were studied by model simulation considering spatial distributions different to the hydraulic conductivity satured of the soil and to pluvial events. The results pointed out the differences among peak outflow can be more than 100% considering minimum and maximumresolution degrees as the precipitation and affirmed the consensus that the acquaintance of the pluvial spatial distribution is fundamental in the adjustment of hydrologic models distributed.

Повний текст джерелаThe general objective was to generate spatial models of abundance predictions of prey of jaguars and cougars in the Neotropics. First, we identified the main prey in the Neotropical region through a literature review. We also assessed if the traditional method of predator identification in the field through faeces appearance would bias the information available. We found that it had an effect, thus we used studies based on high-confidence identification methods. We selected the collared peccary, the white-lipped peccary, the giant anteater, and the spotted paca to generate the spatial models of abundance predictions. First, we used the collared peccary to evaluate whether the geographic variation in the population abundance was related to the location with respect to the centroid of its ecological niche or to the centroid of its geographic range. Moreover, we assessed the shape of the abundance-niche centrality relationship, testing whether the distance to the niche centroid (DNC) defined the maximum expected abundance better than the mean abundance. Furthermore, we tested whether including human influence (HI) improved the relationship between abundance and DNC. Finally, we created a spatial model of abundance predictions of collared peccary using the best model. Secondly, we assessed the importance of HI not only in determining the large-scale patterns of abundance, but also in determining the distribution of the other three prey species: the white-lipped peccary, the giant anteater, and the spotted paca. Specifically, we evaluated whether the addition of HI to the set of environmental variables improved the predictions of the niche models. In addition, we analyzed the relationships between abundance and DNC, abundance and HI, and abundance and both factors together. We used the best abundance model obtained for each species to generate spatial predictive maps of the population abundance. We did not find a significant relation between the abundance of collared peccary and the distance to the geographic centroid. On the contrary, the population abundance of most of the species decreased as the DNC increased. The exception found to this pattern (i.e. the spotted paca) might be related to a greater influence of local factors not included on broader scales. Moreover, beyond the environmental variables, the HI was a very important factor to consider in abundance models, because in most of the species abundance decreased as HI increased. The exception found to this pattern (i.e. the giant anteater) might be related to the degree of tolerance to human pressures. Furthermore, the two peccary species showed both low and high abundances towards the most favorable conditions, whereas the less favorable were characterized only by low abundances. In these cases the best model depended on the quantile analyzed (maximum abundance vs. median abundance), and on the degree of tolerance to human pressures. Finally, high predicted prey-abundance areas were located mainly in the Amazonian subregion of the Neotropical region.

Повний текст джерелаPeatlands play a substantial role in regulating the global carbon balance and concentrations of the greenhouse gases CO2 and CH4 in the atmosphere, and are thus of utmost importance from a climate change perspective. Any changes of peatland functions due to natural or anthropogenic perturbations may result in changes in these ecosystem services. Soil microbial communities are essential drivers of biogeochemical processes, including the carbon cycle. In order to fully understand the effect of environmental perturbations on peatland functions, it is essential to understand how microbial communities are affected. The aim of the research presented in this thesis was to investigate the responses of the peat microbial communities to climate change and increased precipitation of nitrogen(N) and sulfur (S) compounds. High-throughput sequencing approaches were used to investigate the taxonomic and functional composition of microbial communities, and quantitative PCR was used to specifically target the methanogen community. Two field studies including three ombrotrophic peatlands each that differed in climatological conditions and atmospheric N and S depositions, were used to investigate and compare the effect of large- and local-scale environmental conditions on microbial communities. The results show that the variation in geo-climatological (temperature and precipitation) and atmospheric deposition conditions along the latitudinal gradient modulate the peat microbial community composition and the abundance of active methanogens to a greater extent thansite-related microhabitats. Furthermore, a tight coupling between the plant community composition of a site and the composition of its microbial community was observed, and was found to be mainly driven by plants rather than microorganisms. These co-occurrence networks are strongly affected by seasonal climate variability and the interactions between species in colder areas are more sensitive to climate change. The long-term effects of warming and increased N and S depositions on the peat microbial communities were further investigated using an 18-year in-situ peatland experiment simulating these perturbations. The impacts of each of these perturbations on the microbial community were found to either multiply or counteract one another, with enhanced N deposition being the most important factor. While the long-term perturbations resulted in a substantial shift in the taxonomic composition of microbial communities, only minor changes occurred in genome-encoded functional traits, indicating a functional redundancy. This could act as a buffer maintaining ecosystem functioning when challenged by multiple stressors, and could limit future changes in greenhouse gases and carbonexchange.

Повний текст джерелаA informação geográfica assume-se como o ponto de partida para compreendermos o mundo em que vivemos, estando presente nos curricula de várias disciplinas, entre as quais no da Geografia. A sua difusão através dos Sistemas de Informação Geográfica (SIG) tem a vantagem de fornecer aos alunos, uma visão integrada dos problemas, permitindo estimular a exploração individual da informação e em consequência, o desenvolvimento da autonomia e do pensamento crítico. Uma das prioridades actuais na utilização das novas tecnologias passa pela adaptação dos conteúdos à linguagem dos meios, isto é, pela elaboração de material e de estratégias educativas adequadas a um tipo de ensino que tende a recorrer cada vez mais à utilização de ferramentas informáticas. Este trabalho pretende dar a conhecer, através de uma metodologia educacional centrada no Aprender Fazendo, o potencial didáctico que a utilização dos SIG poderá ter no ensino da disciplina de Geografia no 3º Ciclo de Escolaridade. Neste sentido, foram seleccionados diversos conteúdos de dois temas do programa de Geografia para o referido nível de escolaridade e desenvolvidas várias actividades, tendo como recurso o programa informático de SIG para a Educação: ArcVoyager. A sua concretização encontra-se documentada através de um guião de utilização do software e de planificações de aula detalhadas, onde se incluem todos os procedimentos para exploração das actividades, os conceitos temáticos a reter e um conjunto diversificado de exercícios de aplicação. A apresentação destas actividades permite assim antever a possibilidade da utilização das ferramentas de SIG poderem ser exploradas noutros conteúdos curriculares, funcionando como elemento motivacional e facilitador das aprendizagens.

Повний текст джерелаThe aim of the present study is to determine the influence of human activities on fluvial erosion in the Nsikazi District (Mpumalanga). Recommendations for the optimal use of available resources in the study area are made after considering the soil erosion potential of the area, and by comparing the Nsikazi District with the nearby conservation control area, the Kruger National Park (KNP). Soil erosion can be optimally prevented by employing the most suitable management practice; therefore reliable information is required concerning the location, causes and extent of soil erosion. During the present study, satellite remote sensing is evaluated as a cost effective and timely source of information to fulfill this requirement. Due to the fact that soil erosion is a natural process, which can be amplified by certain natural physical factors, it is necessary to determine the natural soil erosion potential of an area before any assumptions can be made regarding the cause of soil erosion. In this study the integration of the natural soil erosion potential map and bare soil map resulted in the establishment of the overall soil erosion potential map for the area. Landuse can be described as the most significant contributing factor in the occurrence of bare soil (devoid of vegetation), and therefore this is an indicator not only of soil degradation, but also of human impact. The data used during the present study consist of digital satellite images (Landsat TM and SPOT) and aerial photographs provided by the Institute for Soil, Climate and Water (ISCW). Additional information was also collected from pre-existing soil and topographical maps of the area. The ILWIS 2.1 computer programme was then employed for image processing and GIS analysis of the data. The study was carried out in two analytical phases. A data processing phase, which was carried out as follows: - The physical erosion factors, which determine soil erosion potential, namely soil erodibility, slope, slope length, slope form and slope aspect as well as plant cover, were converted to GIS data layers and mapped , followed by - the identification and mapping of the presence of bare soil and landuse patterns. A data intergration phase was included, whereby the above mentioned data layers were integrated to determine the natural and overall soil erosion potential, as well as the evaluation of landuse, thereby indicating the soil cultivation potential for the study area.

Повний текст джерелаO estudo de cenários de relações territoriais, através da utilização de processos de análise espacial em Sistemas de Informação Geográfica (SIG), pode constituir um meio de romper com a lógica temática subjacente ao programa de Geografia do ensino básico. Não sendo necessário, de acordo com o Decreto-Lei 6/2001, que o programa seja leccionado segundo a ordem constante nas orientações curriculares, a verdade é que se tem tornado mais simples fazê-lo, até porque os manuais escolares assim se encontram organizados. Propõe-se uma abordagem do programa de Geografia do terceiro ciclo do ensino básico centrada em competências e conceitos de análise espacial em vez de temas específicos, utilizando a flexibilidade permitida pela legislação. O objectivo desta abordagem é o de desenvolver competências que permitam interpretar e manipular informação geográfica. Considera-se que a análise espacial em ambiente SIG poderá ter grande utilidade no terceiro ciclo do ensino básico por promover a interdisciplinaridade, bem como por serem métodos a usar em áreas curriculares não disciplinares. Desenvolvem competências ligadas à análise e tratamento de informação, ao relacionamento com os outros, ao uso das Tecnologias de Informação e Comunicação e ainda competências ligadas ao raciocínio lógico e à resolução de problemas.(...)

Повний текст джерелаEcosystem services (ES) refer to benefits produced and sustained by biodiversity and ecosystems that benefit humans. In many cases, they are not considered in the economic system. This externalization of SE generates decisions on land use and natural resources that ignore their contribution to the well-being of communities. In order to raise awareness of the importance of ES and better integrate them into decision-making processes, economic approaches to value ES have been developed. In this thesis, we sought to understand both how the past and current land use in the Montreal area affects the value of ES and how these natural amenities are perceived and valued by the population in a future planning and management perspective. To accomplish this, we used two approaches: spatial analysis using geographic information systems and analysis of stated preferences by survey techniques. In the spatial analysis approach, we combined cartographic analyzes to monetary values associated to ES published in the literature. We then estimated the value of ecosystems using benefit transfer, direct market prices and avoided costs methods. This approach has allowed us to understand the relationship between the current land use in the Greater Montreal and the economic value of the services provided by ecosystems, which we estimated at 2.2 billion dollars per year. It also allowed us to estimate the effects of land use changes between 1960 and 2010 on the value of ES. We showed that despite different land use planning policies implemented to manage urban sprawl during this period, non-market economic losses related to ES have reached 236 million dollars per year. In the stated preferences approach, we used two methods, contingent valuation and choice experiment, with the aim of measuring the willingness to pay of respondents for proposed changes in their environment. In a first study, we showed that respondents significantly value the impact of agri-environmental practices on the quality of the environment and landscapes and are willing to pay between 159 and 333 dollars per household per year on improving the diversity of agricultural landscape. In a second study, their willingness to pay on improving the status of wetlands in Quebec is estimated at between 389 and 455 dollars per household per year. The combined use of the two methods allowed us to compare the results. We also demonstrated that the choice of valuation question format in contingent valuation affects the convergence of the results. Finally, we propose directions for future research related to the integration of ecological, economic and political analyzes of ES that would lead to better assessments of the dynamics of ecosystems, biodiversity and human communities.
