In the early summer months of the global coronavirus (Covid-19) pandemic, three community-produced participatory videos were conducted on a remote basis. These projects were made in Uganda, Germany and Turkey with the use of mobile technology to understand the impact of the virus on lives of different refugee communities in distant locations around the world. This study evaluates the potential of using the emerging practice of remote participatory video at times of crisis by presenting a case study on one of the participatory video works undertaken in Rhino Camp which is one of the largest refugee camps in Uganda. Drawing on the common production stages within the traditional participatory video practices this thesis presents a preliminary outline for facilitating a remote participatory video. By deploying an affordance approach, it is aimed to investigate how participatory video was translated into a remote practice. By drawing on the Freirean process of critical consciousness the study investigates the ways in which communicative affordances of remote PV could be utilised to promote advocacy during the pandemic. Another objective of the thesis is to explore what unique local experiences and insights could refugees from Rhino Camp bring to bear on the problems caused by the coronavirus pandemic. Focusing on the analysis of the video messages from the refugees of Rhino Camp, the study explores the following question: What significance and potential could the use of remote practice of civil society produced participatory video have during the COVID-19 outbreak?

The settlement history of the Çarsamba alluvial fan is investigated for the interval circa 9,000-1000 BP using Geographic Information System (GIS) tools and satellite remote sensing data. Models of landscape and settlement pattern development are evaluated with reference to the archaeological settlement record. Exploratory data analysis methods are used to examine the spatial characteristics of reconstructed settlement distributions. The use of multi-date Landsat Thematic Mapper (TM) and SPOT Panchromatic satellite data to increase the visibility of past settlements is described within a methodological section of the thesis. Vegetation cover conditions and the contrast between decomposed mudbrick and alluvial soils are identified as important factors in the visibility of settlements. The successful specific detection of previously unrecorded past settlements from Landsat and SPOT data is reported. The archaeological settlement record of the Çarsamba alluvial fan displays complex spatio-temporal patterning as a result of the interaction of cultural and taphonomic factors. While some features of the archaeological record are artifacts of differential preservation or recovery, others clearly reflect the influence of changing physical environments on past landuse and occupation.

Aquest treball exposa els resultats de la investigació doctoral sobre el paisatge històric de la Vall d’Àger amb l’aplicació de la metodologia de l’Arqueologia del Paisatge. S'han utilitzar diferents mètodes científics per obtenir informació heteogènia: des de la teledetecció (lidar i radar), els documents escrits, la prospecció i l’excavació arqueològica, fins a la anàlisis de l’arquitectura i l’aplicació dels models de l’arqueologia predictiva (least cost path, site catchment analysis, viewshed analysis etc.). Els objectius consisteixen en la clarificació de les dinàmiques dels assentaments rurals en l'Edat Mitjana, des de el segle V fins al XIII, a través de l'anàlisi dels assentaments, de les vies de comunicació, del paisatge agrari i dels sistemes defensius i de l'estructura eclesiàstica. Aquest estudi ha demostrat que l’estructura del paisatge de la Vall d’Àger es genera amb un primer impuls entre els segles V i VII, i posteriorment experimenta un profund canvi a partir de finals del segle X.
Este trabajo trata de analizar el paisaje histórico del Valle de Àger (España) a través de múltiples fuentes, como las fuentes escritas, la teledetección, las fuentes arqueológicas, las arquitecturas históricas y los análisis del parcelario agrario, de la viabilidad y de la toponímica. El objetivo principal es el de analizar la periodización del asentamiento medieval de forma general y detallada a través del estudio del paisaje fortificado y del paisaje sagrado en una ventana cronológica que va desde el siglo 5 hasta el siglo 13. También se analizaron los elementos principales de las arquitecturas históricas disponibles mediante los métodos de la arqueología de la arquitectura. Otra aplicación metodológica fue la de la Archéogéographie Francesca a través de la cual es posible estudiar las estructuras del parcelario agrario y de la viabilidad. Todos los datos han sido sintetizados para obtener el cuadro general del asentamiento medieval en el valle.
This work deals with the analysis of the Ager Valley historic landscape through the methodologies of Landscape Archaeology. It uses several multidisciplinary sources as written documents, remote sensing images (mainly lidar and radar), parcels analysis, archaeological prospections and archaeological excavations. The main target has been obtaining the periodisation of the medieval settlement in the valley from the 5th to the 13th centuries. It analyses the structure of the agrarian parcel systems through the methodology developed in the Archaeogeographic studies and predictive archaeology (least cost path, viewshed analysis, site catchment analysis). It also uses the application of the Archaeology of Architecture in order to study the material evidences of the churches and the defensive towers of the valley. After the analysis of the different sources, it tries to develop a synthesis of the data following the chronological windows allowed by the sources. All the data have been used also to analyse the Landscape of Power and the Sacred Landscape in the valley during the Middle Ages.

As causas relacionadas ao desmatamento que ocorre na região Amazônica estão vinculadas aos diferentes usos e ocupações dessa área, entre eles os assentamentos rurais implantados pelo INCRA. Desta forma, com um estudo de escala local, o objetivo desta pesquisa foi investigar quais são os fatores sociais, econômicos e institucionais que influenciam no uso da terra e no desmatamento no Projeto de Assentamento Matupi, localizado no município de Manicoré, sul do estado do Amazonas. Para a avaliação das mudanças no uso da terra e do desmatamento foram utilizadas as informações geradas pelo PRODES/INPE no período de 2000-2010. As características sócio-econômicas foram levantadas a partir da aplicação de 121 questionários com os responsáveis pelo lote no assentamento Matupi. Utilizou-se o Modelo de Regressão Multivariada (MRM) para selecionar as variáveis sociais, institucionais e econômicas (variáveis independentes) que explicam o uso da terra e o desmatamento (variável dependente) no PA Matupi. No período analisado observou-se que a conversão de áreas de floresta em uso da terra tem aumentado no PA Matupi e para os lotes da amostra de 121 entrevistados, 90,9% dos responsáveis pelo lote utilizam mais de 20% de sua área, principalmente com a atividade da pecuária. Das 28 variáveis independentes, apenas atividade atual do lote, assistência técnica, utilização de equipamentos e máquinas, responsável pelo lote, local de moradia antes da chegada ao assentamento, origem dos responsáveis pelo lote, produtos comercializados e comercialização dos produtos foram selecionadas para explicar o uso da terra e o desmatamento na área estudada. Desta forma, estudos locais e que integrem os fatores sociais, institucionais e econômicos são necessários para se avaliar a real contribuição dos projetos de assentamentos do INCRA no desmatamento da região, contribuindo para o planejamento de novos assentamentos na região, que visem ao desenvolvimento social, econômico e ambiental.
Causes related to the deforestation in the Amazon region are linked to different uses and occupations of this area, including rural settlements implemented by Incra. Thus, through a local-scale study, the objective of this research was to investigate which are the social, economic and institutional influences on land use and deforestation in Matupi Settlement Project, in the municipality of Manicoré, in the southern region of the state of Amazonas. For the assessment of changes in land use and deforestation, information generated by PRODES / INPE, in the period 2000-2010, were used. The social-economic characteristics were obtained from the application of 121 questionnaires with those responsible for the lot in the Matupi settlement. We used the Multivariate Regression Model (MRM) to select the variables social, institutional and economic factors (independent variables) that explain land use and deforestation (dependent variable) in PA Matupi. The analysis showed that the conversion of forest land to use has increased in Matupi PA and for 121 respondents, 90.9% use more than 20% of the lot, especially with the activity of livestock. Of the 28 independent variables, only the current activity in the lot, technical assistance, use of equipment and machinery, responsible for the lot, place of residence before arriving at the settlement, origin of the responsible for the plot, and marketing of products and marketed products have been selected to explain the land use and deforestation in the area. Thus, local studies integrating social, economic and institutional factors are needed to assess the real contribution of the INCRA settlement projects in the deforestation of the region, contributing to the planning of new settlements in the region, aimed at the social, economic and environmental development.

Resumo: Esta pesquisa contribui para o debate sobre o processo de desflorestamento na região Amazônia, a partir de uma abordagem fundamentada na análise da evolução espaço-temporal do uso e ocupação do assentamento rural de Machadinho d'Oeste, Rondônia, tendo como material básico de estudo, dados de sensoriamento remoto e dados socioeconômicos. Considera-se neste estudo que, o processo de desflorestamento regional é conseqüência direta da expansão da fronteira agrícola iniciada no final da década de 60, impulsionada pelas políticas de incentivos governamentais de ocupação e desenvolvimento local. O objetivo foi avaliar se as taxas de desflorestamento das propriedades estavam em acordo com a legislação ambiental - em especial, o Zoneamento Socioeconômico-Ecológico do estado de Rondônia. Para isto, dados de um mapeamento multitemporal de uso e cobertura das terras elaborado a partir de imagens orbitais Landsat TM, para os anos de 1988, 1994 e 1998, foram utilizados como instrumento de monitoramento da evolução do desflorestamento em propriedades situadas na Gleba 2 do assentamento. Foram diferenciados 3 tipos de produtores residentes na área de estudo: os que desflorestaram até 60% da área de suas propriedades - limite proposto no ZEE, e aqueles que desflorestaram área excedentes a este percentual, subdivididos ainda de acordo com o ritmo inicial do desflorestamento: intenso, se a taxa estivesse acima de 10 ha nos 5 primeiros anos e não-intenso, se a taxa de desflorestamento fosse inferior a 10 ha nos primeiros 5 anos. Estes resultados provenientes do sensoriamento remoto foram integrados a dados socioeconômicos dos produtores rurais, obtidos por meio de entrevistas realizadas pela Embrapa em 1986 e 1996, com o objetivo de se resgatar a dimensão humana do processo de desflorestamento ocorrido na área de estudo. Nesta etapa, foram analisadas variáveis demo gráficas, relativas à propriedade e variáveis econômicas dos produtores assentados, com o intuito de inferir sobre os possíveis fatores condicionantes do desflorestamento nestas propriedades. As principais conclusões indicaram que dentre as variáveis estudadas, idade do produtor, pessoas na família, tempo de residência, ativos agrícolas, mão-de-obra extra-familiar, assistência técnica, número de proprietários anteriores e nível de riqueza apresentaram associação direta com o padrão de desflorestamento praticado. E as variáveis origem do produtor, área da propriedade, atividade extra agrícola e acesso a linhas de crédito não apresentaram associação
Abstract: This research aims to contribute to the debate on Amazonic region deforestation process through an analysis on the spatial-temporal evolution of use and occupation of the rural settlement Machadinho d'Oeste in Rondonia based on remote sensing and socioeconomic data. We consider that the deforestation process results directly of the expansion of agricultural borders begun at the end of the sixties promoted by governmental policies of occupation and local development. The aim was to evaluate the accordance of the deforestation rates in each property with the environmental law - specially the Rondonia state law on Ecological Socioeconomic Zoning (ESZ). As an instrument for monitoring the deforestation evolution in properties located at Gleba 2 of the settlement, we used data obtained from a multitemporal mapping of land use and land cover made from Landsat TM satellite remote sensing images taken in 1988, 1994 and 1998. Three kinds of producers were identified in the study area: those who deforested up to 60% of their lands - limit proposed by the ESZ - and those who over deforested the permitted 60%. The latter group was divided according to the initial deforestation rhythm: intense, rates over 10 ha in the first 5 years and non-intense, rates under 10 ha in the first 5 years. These outcomes from remote sensing data were crossed with socioeconomic data obtained by Embrapa through interviews with rural producers in 1986 and 1996 aiming to comprehend the human dimension of deforestation process occurred in the area. In this stage were analyzed demographic and economical variables concerning property and settled producers, in order to infer about the possible leading factors to deforestation in these properties. The main conc1usions have shown that amongst the considered variables some presents direct association with practiced patterns of deforesting, such as: producer's age, number of people in the family, years lived on the farm, number of people working the land, number of extra-familiar workers, technical assistance, number of previous owners and leveI of wealth. Other variables such as: producer's origin, property' s extension, extra-agricultural activities and access to credit lines have not presented association with the above mentioned patterns of deforesting

I conducted a 12-month study of near-shore habitats in Lake Pontchartrain to assess spatiotemporal variation in the abundance of early life stage blue crabs (Callinectes sapidus). Collections were made using a 1 m2 throw trap and data showed that C. sapidus numbers varied over time and among sites. Two recruitment events occurred during the study. During the first recruitment in May-June, C. sapidus entered Lake Pontchartrain via the Inner Harbor Navigational Canal. In September-October, C. sapidus entered the Lake Pontchartrain via the Rigolets and Chef passes. My data suggest that C. sapidus utilize water circulation within the Lake Pontchartrain as a means of transportation throughout the estuary. MODerate-resolution Imaging Spectroradiometer (MODIS) 250 m data were analyzed to gain a large-scale view of suspended sediments patterns within Lake Pontchartrain and quantify water movement. Field sampling along with remote sensing proved to be beneficial when assessing estuarine-wide C. sapidus post-larval dispersal processes.

The Etruscan civilization was rich in local and interregional trade. Its exchange networks were vital in establishing relationships with other societies, importing exotic materials and goods, as well as disseminating and assimilating information. However, there is little understanding of the participation of smaller inland settlements in the act of exchange. This research answers questions pertaining to the purpose of trade within these self-sustaining communities, the reliability of identifying geographic locations of the clay used in ancient ceramics through the use of non-destructive X-ray Fluorescence (XRF) spectrometry without sampling current regional clay sources, and the materiality of the ceramics being exchanged in order to establish major forms of production for each settlement. The analyses of trace elements contained within the ceramic materials previously excavated from two remote Etruscan sites (La Piana and Cetamura) can provide a greater understanding of both the trade practices of the Etruscan culture and the reliability of the sourcing methods. Over 100 ceramics ranging from storage containers, bricks and roofing tiles, amphorae, loom weights, and tableware (including red and black gloss) from Cetamura and La Piana were selected to represent a sample base for local and non-local crafted ceramics. The artifacts were analyzed non-destructively using a Bruker Tracer III-SD portable X-ray fluorescence spectrometer (pXRF), which has been shown to be highly successful in other archaeological studies. Six trace elements (rubidium, strontium, yttrium, zirconium, niobium and thorium) of each artifact were recorded and analyzed using principal component analysis to create a comparable data set. The results confirm that while these Etruscan settlements were self-sustaining, they were still participating in long-distance exchanges.

A crescente ocupação urbana desordenada e inadequada vem acarretando sérios problemas ao meio ambiente nos últimos anos. Em algumas cidades, os assentamentos urbanos são localizados principalmente em regiões de encosta sem nenhum critério técnico ou projeto ambiental. Esse tipo de irresponsabilidade tanto da população como do próprio governo geram transgressões de leis ambientais e freqüentes acidentes nas épocas de chuvas torrenciais, resultando em grandes tragédias. Portanto, o estudo dos diversos tipos de uso do solo associado as suas características físicas é de extrema importância para o entendimento dos processos de preservação e conservação dos recursos naturais, e principalmente em relação à restrição ao uso das terras em áreas de risco de deslizamento, assegurando assim a qualidade de vida da população. Esta dissertação propõe a analise da legislação ambiental do município de São Sebastião no Estado de São Paulo através do uso do Sensoriamento Remoto e Geoprocessamento. A área de estudo tem uma extensão de 402,3 Km2 e está localizada no Litoral Norte de São Paulo. Este município apresenta uma pressão da expansão urbana que acarreta sérios problemas de deslizamentos nas épocas de chuva devido a assentamentos irregulares. A metodologia utilizada foi adaptada da proposta por CREPANI et al. (1996) e MORAES (1999). Neste trabalho foram utilizadas as imagens dos sensores TM, ETM+ e HRV dos satélites Landsat 5, 7 e Spot dos períodos de 1988 a 2002, assim como do Shuttle Radar Topographic Mission (SRTM) de 2000. A partir das imagens orbitais gerou-se um mapa temático de uso e cobertura do solo, e da imagem de radar as isolinhas e a carta de declividade da referida área de estudo. Estes produtos foram integrados e/ou cruzados juntamente com as variáveis ambientais de geologia, geomorfologia, geotecnia e solos resultando no Mapa de Aptidão Física ao Assentamento Urbano. Este último foi integrado com o Mapa de Legislação Ambiental que contém as Áreas de Preservação Permanente (APP`s) para gerar finalmente o Mapa de Incompatibilidade ao Uso. Todos os cruzamentos foram executados através da Linguagem Espacial para Geoprocessamento Algébrico (LEGAL) do software SPRING. Os resultados obtidos mostraram que existem poucas áreas compatíveis ao Uso, devido a Legislação Ambiental e também as características físicas da região. Existe ainda um avanço antrópico permanente em áreas de risco de deslizamentos e nas proximidades do limite do Parque Estadual da Serra do Mar (PESM), comprovando o desrespeito às leis ambientais. A identificação das áreas compatíveis para o assentamento urbano pode impedir a expansão do crescimento antrópico em áreas de risco, e também sobre a degradação ambiental em regiões de preservação no município de São Sebastião.
In the last few years, increasing urban occupation considered inadequate and disordered is recognized to be a serious environmental problem. In some cities, the urban settlements are also located in areas of sliding land, which are occupied without any technical criterion or environmental project. Such irresponsible actions by the citizens and bye the government are roots of transgressions of environmental laws always leading to land sliding accidents and tragedies during torrential rainfalls. Therefore, investigating several types of land use associated to physical soil characteristics are extreme important for understanding the actual preservation and conservation processes associated to natural resources, especially, on issues relating to the restrictions of use and occupation in areas of land slide, in order to assure life quality of the population. This dissertation intends to analyze the environmental legislation of the municipality of São Sebastião in São Paulo State, applying Remote Sensing and Geographic Information System. The study area extension is about 402.3 km2 and is located in the North Coast of São Paulo State. Due to irregular settlement associated to areas of urban pressure and expansion, the municipal area is actually subjected to land-sliding problem during raining season. Method used has adapted proposed ideas of CREPANI et al. (1996) and MORAES (1999). Were used images of TM, ETM+, HRV sensors of satellites Landsat 5, 7 and Spot of period from 1988 to 2002, and also of the Shuttle Radar Topographic Mission (SRTM) of 2000. Using the orbital images was generated a thematic map of land use and cover, while the radar image has treated the isolines and declivity. Both products were crossed and integrated analyzed with others environmental variables of geology, geomorphology, geotechnical and soils that have resulted into a general Map of Urban Settlement considering Physical Capacity. This was linked with the Environmental Legislation Area Map containing the Areas of Permanent Preservation (APP`s) for determination of Land Use Incompatibility Map. All the crossings procedures were made using The LEGAL language (Linguagem Espacial para Geoprocessamento Algébrico) of SPRING software was utilized for all crossed analyses. Final results have revealed that there are only few areas that are available relating compatible Use and to the Environmental Legislation combined with the physical characteristics of the area. However, anthropic occupation is expanding continuous in sliding risk areas and also by the boundaries of Parque Estadual da Serra do Mar (PESM), where environmental laws where not obeyed. The awareness of compatible Use for the urban settlement may aid in order to assist the expansion or anthropic occupation in risk areas, and also to avoid environmental degradation where preservation is expected in the municipality of São Sebastião.

Em países em desenvolvimento, doenças infecciosas se constituem ainda um grave problema de saúde pública. Muitas vezes, essas doenças estão altamente relacionadas a condições urbanas que podem ser encontradas em áreas mais pobres. Nesses casos, o sensoriamento remoto (SR) pode ser utilizado como uma poderosa ferramenta de estudo. Novos produtos de SR se encontram disponíveis no mercado, permitindo o desenvolvimento de análises espaciais cada vez mais profundas e precisas. No entanto, a complexidade que envolve a epidemiologia de doenças, a irregularidade de ocupações urbanas e a heterogeneidade das imagens de alta resolução espacial têm restringido o desenvolvimento de estudos nesse campo científico. O desafio de identificar elementos e tipologias urbanas em imagens de sensoriamento remoto relacionadas à ocorrência da leptospirose justifica-se pela crença de que ferramentas de SR podem ser mais amplamente utilizadas no monitoramento de carências urbanísticas e, consequentemente, na gestão de ações e investimentos públicos. A metodologia contempla uma revisão bibliográfica sistemática, com base na qual foram criados modelos de transmissão da leptospirose e investigadas tipologias urbanas presentes na área de estudo. As variáveis baseadas em dados de SR que formam os indicadores dos modelos e que caracterizam as tipologias foram usadas para definir objetos e atributos, alvos das investigações em imagens de alta resolução espacial. Os procedimentos de SR adotados baseiam-se na segmentação multi-nível, classificação baseada em objeto, e utilizam ortofotografias aéreas, imagem QuickBird e base cartográfica do eixo viário do Subúrbio Ferroviário de Salvador. Para o cálculo das variáveis utilizou-se produtos do processamento da imagem QuickBird. Procedimentos de geoprocessamento foram realizados em sistema de informações geográficas. Por fim, realizaram-se as primeiras análises epidemiológicas que investigam a relação da leptospirose com os elementos e tipologias urbanas identificados por meio de SR, cujos resultados apontam maior influência do percentual de pavimentação das vias, sua largura e qualidade da edificação na possibilidade de ocorrência da leptospirose no Subúrbio. Possíveis fontes de viés são discutidas ao lado de propostas de continuação da pesquisa. Apesar dos problemas e limitações identificados no processo, o estudo mostra que a metodologia desenvolvida baseada em SR se constitui uma poderosa ferramenta de análise do espaço intra-urbano, uma vez que permite a identificação de elementos e tipologias relacionados a situações de risco, apoiando assim, o direcionamento de investimentos públicos que venham refletir na melhoria das condições de saúde da população.
In developing countries, infectious diseases are still a serious public health problem. These diseases are often and highly related to urban conditions found in poor areas, in these cases, remote sensing (RS) can be used as a powerful tool. New RS products are now available allowing the development of more complex and precise spatial analysis. On the other hand, the complexity of epidemiological studies, the lack of regularity of precarious urban settlements and the heterogeneity of high spatial resolution images have been restricting the development of studies in this areas. The challenge of identifying urban elements and typologies related to the leptospirosis using RS products is pursued due the belief that RS can be more used among professionals and researchers in the task of monitoring the urban environment, and directing public investments and actions. The methodology presented consists in a broad literature review, which was used to support leptospirosis transmission risk models and to find urban typologies at the study area. Variables based on RS were identified in the disease models and in the typologies characterization. This models and typologies also defined targets to look for in the high spatial resolution images. RS procedures were based on multi-level segmentation, object-based classification, aerial photography, QuickBird satellite images and street axis vector data of the Railroad Suburb of Salvador. In order to obtain the variable\'s values, results of QuickBird image processing were added to a geographic database and processed using vector and raster over layering techniques. At last, epidemiological analysis were initiated aiming to find its relationship with the urban elements and typologies identified using RS. The results points paved streets, streets wideness and house quality as the RS variables that have more influence on the leptospirosis transmission chance. The dissertation also presents research restrains, potentials, possible sources of bias and future studies proposals. It concludes that the RS based methodology presented is a powerful tool for urban analysis, due to its capabilities for identifying urban targets related to risky situations, and, therefore, for helping direct public investments to improve life conditions an unprivileged city areas.

This study utilizes an integrated remote sensing approach to augment settlement pattern research in the Yalahau Region of northern Quintana Roo, Mexico. The region has a long history of human occupation and an environment ranging from coasts, freshwater wetlands, forests, to fields and towns all above a porous karst geology. By utilizing various sensors (LiDAR, GeoEye and Landsat) and collection methods (satellite, aerial) as well as post-processing (band combinations, component analyses and indices) and cross-referencing the data, it is possible to generate a signature, which strongly correlates with evidence of prehistoric occupation. Field verification of a selection of identified signatures was conducted to assess the presence of human cultural material. The results of this investigation are presented together with other regional settlement pattern data in order to assess the status of a number of methodological and archaeological questions and supplement other regional data already available.

In this dissertation, I explore the relationship between water management, urbanism, and socio-political organization at the Classic Maya site of Xultun, Guatemala. In an area without permanent surface water, provisioning and maintenance of large stores of water was a necessity for agricultural stability. Combining evidence from archaeological survey, excavation, remote sensing, and geospatial analysis I demonstrate that settlement at Xultun was organized topographically. Elite ritual structures were concentrated on the highest areas, and in proximity to reservoirs. This gave leaders control over the release of water, and by extension control over their subjects. Xultun was built on a natural hill. Urban space was concentrated into three topographic areas: administrative on the summit, residential on lower terraces, and agricultural on the lowest land. Using geospatial analysis, I modeled the relationship between the site's public and private buildings, its 15 reservoirs, and its hydrology. Water was collected and stored within each of the three topographic zones for local use; however, administrative neighborhoods were located close to reservoirs in order to maintain tight control. Excavations at the site's summit revealed that the central reservoir was in use since the late Preclassic (400 BC-250 AD). They also revealed a complex drainage system that diverted water into an aqueduct that emptied into a canal feeding this reservoir. Overflow from the reservoir was directed to reservoirs further downhill. Drainage flowed from the administrative center to the cardinal directions in accordance with Maya cosmological principles. The link between water and authority is further illustrated by the discovery, in an administrative neighborhood, of a stela depicting a royal ancestor in the act of impersonating Chak, the Maya rain god. At Xultun, the association of administrative neighborhoods with reservoirs in all three topographic areas reflects centralized control and management of urban water resources. The arrangement of hydrological systems emphasized cosmological principles and reinforced authority through ritual association with the rain deity. Water management was instrumental in the maintenance of power. As a key element of statecraft, its stratified spatial organization supported the hierarchical social order that took root in the Preclassic and came to characterize Maya urbanism.

This dissertation investigates the role of the seasonal wetlands in the political economy and subsistence strategies of the ancient Maya of Chunchucmil, Yucatan, Mexico. A combination of pedestrian surveys and remote-sensing tasks were performed in order to better understand the settlement patterns and potential communication routes in and through the wetlands between Chunchucmil and the Gulf of Mexico. These western wetlands had been proposed as the principal avenue for interregional trade between coastal merchants and inland consumers, yet were thought to be uninhabited and uncultivable. Following the survey tasks outlined in this dissertation, these wetlands were found to contain an abundance of archaeological settlements and features indicating habitation, utilization, and trade throughout this diverse ecological zone The remote-sensing platforms utilized in this study include both multispectral (Landsat) and synthetic aperture radar (AirSAR), combined with additional remotely sensed resources. One of the goals of this survey was to test the capabilities of these two sensors for the direct detection of archaeological features from air and space. The results indicate that Landsat can be highly successful at detecting site location and measuring site size under certain environmental conditions. The Airborne Synthetic Aperture Radar proved to be adept at detecting large mounded architecture within the Yucatecan karstic plain, but its further utility is hampered by limitations of resolution, scale, and land cover One of the salient features of the landscape west of Chunchucmil is a network of stone pathways called andadores. These avenues through the wetlands outline a dendritic network of communication, trade, and extraction routes. The following dissertation places this network and its associated settlements (from suburban centers to diminutive camps) within their regional context, examining the roles they may have played in supporting a large mercantile economy centered at the site of Chunchucmil

While there is a growing body of research on taking people to Mars, as well as on the environmental control and life support systems required to keep humans alive both during the journey and on Mars, there is very little research to support the development of successful new settlements. This research explores the challenges faced by remote villages in harsh environments and how their residents have learned to adapt to these challenges. Accessing this existing knowledge opens opportunities for future settlement on Mars as well as on Earth. Research into remote villages as a form of settlement separate to rural settlement is a comparably new field within human geography. Recently for example the Carsons (2011; 2014) have identified a list of common features of remote villages. However past indices have used features of marginality as markers in identifying remote villages (Cloke, 1977; Cloke and Edwards, 1986) thus creating or at least strengthening an image of remote villages as chronically troubled and in decline. While there exist a number of different definitions and indices for identifying remoteness none appears to cater to the multi-facetted nature of remoteness. Besides the physical component of remoteness, the phenomenon has been shown to include cultural (Huskey, 2005, 2006; Schmallegger et al., 2011; Ardener, 2012; Gilbert, Colley and Roberts, 2016) as well as political (Harvey, 2000; Huskey, 2005; Rogers and Walker, 2005) aspects. At the other end of the spectrum remote villages have been associated with utopian ideals, as can for example be seen in the Israeli Kibbutz movement (Zilbersheid, 2007). The proposition was brought forward by this study that rather than being either utopias or dystopias remote villages might in fact be heterotopias. Heterotopias are places of otherness, places that are disconnected from the mainstream by both physical and socio-cultural barriers and where social rules different from the mainstream can exist (Foucault and Miskowiec, 1986; Hetherington, 1997). This study used an inductive research approach of extreme case studies, using open-ended interviews and qualitative coding techniques. The methodology was most heavily influenced both by Flyvbjergs' (Flyvbjerg, 2006, 2009) ideas on case study research and Birks & Mills' (2011) understanding of grounded theory. During 2015 five villages in northern Sweden and southern Israel were visited for this study. These sites were chosen using a multi-parameter matrix that catered for the multi-facetted and often relative nature of remoteness. During research in the case studies observations on three types of challenges were found: those challenges that were uncontrollable prerequisites of settlement ("environmental challenges"), those challenges that were brought about by political and social realities outside of the community's immediate control ("infrastructure challenges"), and those challenges that referred directly to the village community ("community challenges"). Overall challenges faced by villages in both regions were remarkably similar though influenced by factors such as the villages' age and settlement history. The data from this study showed four common phenomena characterising village life in remote and harsh regions. Firstly, the harshness of terrain and climate provides residents with a sense of place. Secondly, residents described a strong 'do-it-yourself'-attitude and volunteering culture. Thirdly, there was a high occurrence of different types of self-employment that signified that the lack of employment options was not as significant as expected. Finally, and most importantly, residents were attracted to what life in a remote village could offer, and in particular, the opportunities that could be provided that were different from mainstream society. Using the findings from this study the phenomena listed by the Carsons (2011; 2014) could be put in relation to each other. In doing so I was able to contribute to explaining the co-occurrence of these phenomena and at the same time I identified a missing link. In the following I proposed that the observed co-occurrence of phenomena can be explained through remote villages being heterotopias. Research findings showed that at least the villages in this study can be described as heterotopias. If indeed remote villages are heterotopias, then they can be expected to have a two-way relationship with the mainstream. The villages of this study could be shown to conform to Ravens' (2015) and Hetheringtons' (1997) notion of heterotopias as places of utopics, that is places that through their striving towards utopia create a high innovative potential that could be described as that of a 'living laboratory' (Raven, 2015). The question then follows how to support remote villages in accessing this potential for innovation. This study proposes the use of structure and agency theory for these means: From the case study data we know residents of the case study sites to have strong agency, that is a willingness and capability to self-solve problems that arise from their villages' remoteness. However as suggested by structure-and-agency theory, agents need a supporting structure in order to be able to exercise this agency. For remote villages this means that while local decision-making and resource allocation are to be encouraged this cannot be used as an excuse for removing structure, as structure is vital for agency. Due to the research design of this study, using a small number of extreme cases, the findings of this study cannot be generalised. However, as the case studies were based on an approximation of a future Martian village the findings of this study are very likely to be applicable to this particular kind of village. Next steps in research need to establish parameters and identifiers of remote villages that enable future research to conduct larger, quantitative studies. Through such generalisable research we will be able to establish whether all types, or just a particular type of remote village are or can be heterotopias.

The Chenyulan river is located in Nantoucountry, the mainstream flow from south to north. Owing to steep topography, landslide activity more, alluvial fan area and river terraces are developed. In recent years, natural disasters such as debris flow usually occur after typhoon and rainstorm in Chenyulan river. So the safety of each settlement along the river by impact of river topography changes is very importment. In this study, the study area include Feng-Qiu, Xin-Xiang, Lona, Wang-Xiang and Tong-Fu settlement in Chenyulan river. Because these area is belonging to densely populated areas, when disaster strikes, these area are high hazards.This study used multi-source aeril photography and remote sensed imagery to detect river changes at Feng-Qiu settlement to Tong-Fu settlement in Chenyulan river. Various types of maps were used in this study, including old aeril images taken in 1946, Corona satellite images acquired in 1971, and orthophoto taken in 2002. This study use GIS(Geographic Information System) software to digitize river area range, river channel, river terraces, alluvial fan terraces and use DTM(Digital Terrain Model) and profile analysis to analysis was applied to find the river changes in different time periods. The result shows that, by using multi-source aeril photography and remote sensed imagery and analysis functionalities of GIS can determine the relative risk level of each settlement, such as: the lower relative risk settlement including Feng-Qiu, Xin-Xiang, Lona, Wang-Xiangterrace. The higher relative risk settlement including Shih-Ba-Chun River, Non-Fu- Ping, and Tong-fu terrace. The study results provide reference for future settlements along the river disaster prevention and risk assessment.

During the past two centuries, land cover has been changing at an alarming rate in space and time and it is humans who have emerged as the dominant driver of change in the environment, resulting in changes of extraordinary magnitudes. Most of these changes occur due to demands placed on the land by the ever-increasing human population and their need for more land for both settlement and food production. Many researchers underscore the importance of recognizing and studying past land-use and land cover changes as the legacies of these changes continue to play a major role in ecosystem structure and function. The objectives of this study were to determine the extent of land cover changes between 1992 and 2008 in the study areas, Esikhawini and Dube located in the uMhlathuze municipality, KwaZulu-Natal, and to both predict and address the implications of the extent of future changes likely to occur in the area by 2016. Three Landsat satellite images of the study area were acquired for the years, 1992, 2000 and 2008. These images were classified into nine classes representing the dominant land covers in the area. An image differencing change detection method was used to determine the extent of the changes which took place during the specified period. Thereafter, a Markov chain model was used to determine the likely distribution of the land cover classes by 2016. The results revealed that aside from Waterbodies and Settlements, the rest of the classes exhibited a great degree of change between 1992 and 2008, having class change values greater than 50%. With regards to the predicted change in the land cover classes, the future land cover change pattern appears to be similar to that observed between 1992 and 2008. The Settlements class will most likely emerge as the dominant land cover in the study area as many of the other classes are increasingly being replaced by this particular class. The overall accuracy of the classification method employed for this study was 79.58% and the results have provided a good overview of the location and extent of land cover changes in the area. It is therefore plausible to conclude that these techniques could be used at both local and regional scales to better inform land management practices and policies.

Rapid growth of cities is a global phenomenon exerting much pressure on land resources and causing associated environmental and social problems. Sustainability of land resources has become a central issue since the Earth Summit in Rio de Janeiro in 1992. A better understanding of the processes and patterns of land cover change will aid urban planners and decision makers in guiding more environmentally conscious development. The objective of this study was firstly, to determine the location and extent of land use and land cover changes in the uMhlathuze municipality, KwaZulu-Natal, South Africa between 1992 and 2002, and secondly, to predict the likely expansion of urban areas for the year 2012. The uMhlathuze municipality has experienced rapid urban growth since 1976 when the South African Ports and Railways Administration built a deep water harbour at Richards Bay, a town within the municipality. Three Landsat satellite images were obtained for the years, 1992, 1997 and 2002. These images were classified into six classes representing the dominant land covers in the area. A post classification change detection technique was used to determine the extent and location of the changes taking place during the study period. Following this, a GIS-based land cover change suitability model, GEOMOD2, was used to determine the likely distribution of urban land cover in the year 2012. The model was validated using the 2002 image. Sugarcane was found to expand by 129% between 1992 and 1997. Urban land covers increased by an average of 24%, while forestry and woodlands decreased by 29% between 1992 and 1997. Variation in rainfall on the study years and diversity in sugarcane growth states had an impact on the classification accuracy. Overall accuracy in the study was 74% and the techniques gave a good indication of the location and extent of changes taking place in the study site, and show much promise in becoming a useful tool for regional planners and policy makers.

`This thesis examines the development and maintenance of a fragile group identity at the community level among Aboriginal people in the West Kimberley in Western Australia. It focuses on the town-based Aboriginal settlement of Junjuwa in Fitzroy Crossing. With no indigenous political structures relevant to the permanent co-residence of several hundreds of people the development and maintenance of a community sentiment powerful enough to allow the effective operation of the community as an administrative unit is problematic. While the material constraints of successive government policies have been a key limitation on people, indigenous identities, groupings and associations which pose obstacles to sustaining a commitment to the community are always present and constantly threatening it. This thesis explores the bases of cohesion at the community level and the constant tension with sub-community loyalties of one kind or another. It begins with a consideration of aspects of the historical background that are crucial to understanding the contemporary situation, paying particular attention to the transformations in residence patterns brought about by the pastoral industry. The emergence of Junjuwa is described in the context of the pastoral industry in the 1960s, which forced many Aboriginal people into Fitzroy Crossing. This is followed by an analysis of the community constitution, the physical structure and the resident population. In the subsequent Chapter, the bases of group sentiments and the circumstances in which these were expressed and operated are analysed. Chapters six and seven examine the sub-groupings, associations and identities that are in constant tension with the community identity. Chapter eight concentrates on the leadership in the community and Chapter nine on the consequences of external interventions. In the final chapter I discuss why the factors that make the emergence of a community sentiment at the level of associations like Junjuwa are not, at present, expendable to the regional level.

The Structure and the Chronology of Stroked Pottery Culture Settlements in Eastern Bohemia; This work covers the period of the Stroked Pottery Culture (5100/5000 - 4500/4400 cal BC) in a spatial context that in accordance with the current territorial administrative division corresponds to the Pardubice and the Hradec Králové Regions (Central Europe, Czech Republic). It describes and compares the forms and the composition of the two adjacent areas of Neolithic settlements. Attention is focused primarily on the Hradec Králové area, where two main sites are being studied, i.e. Jaroměř and Plotiště nad Labem. Through analysis of the archaeological material and contextualisation of the results within the wider framework of the Eastern part and subsequently also the entire area of Bohemia it is seeking to identify the hierarchical structure of the settlement. On the basis of the documents of remote distribution it also seeks to identify within this structure any evidence of the presence of groups or individuals with exceptional social status.

The successes and failures of interventions to close the disadvantage gap for remote Aboriginal communities have been well documented but the role of the non-Indigenous advisers tasked with carrying out those interventions has remained obscure. This study explores the development of the culture of non-Indigenous government staff living and working in remote Aboriginal settlements in Central Australia in the 1960s and early 1970s. Elements of Constructivist Grounded Theory Methodology and its methods were used to analyse interviews of a representative group of workers. Three core themes were identified: Confronting disconnectedness, Finding our own space within the institution, and We formed a new social framework. Further analysis led to a descriptive narrative that incorporated personal characteristics, social processes, reactions to ambiguous governance structures, and the creation of a new social structure. From this analysis, three propositions can be drawn: (1) Remote communities with an absence of governance structures attracted workers characterised by a preference for autonomy and self-organisation, workers who sought difference, meaning and adventure. (2) Remote Aboriginal settlements with inadequate governance structures resulted, paradoxically, in social connectedness being contingent on the ability to maintain and navigate distance from other people. (3) The stronger the governance structures, the more cohesive the group. This led to less need for external networking, which, in turn, lessened the likelihood that remote workers would be influenced by other external factors. The relationship between the strength of governance structures and the workers’ personal characteristics determined how, and with whom, non-Indigenous workers formed meaningful connections. Conclusions: The ongoing heterarchical network – an unranked collective of absent, unclear or frequently changing hierarchies - that is identified in this thesis, would likely benefit from the development of a national peak body which could aggregate and maintain an organisational structure, and formalise training and the maintenance of professional standards of workers in remote settlements.

abstract: Slum development and growth is quite popular in developing countries. Many studies have been done on what social and economic factors are the drivers in establishment of informal settlements at a single cross-section of time, however limited work has been done in studying their spatial growth patterns over time. This study attempts to study a sample of 30 informal settlements that exist in the National Capital Territory of India over a period of 40 years and identify relationships between the spatial growth rates and relevant factors identified in previous socio-economic studies of slums using advanced statistical methods. One of the key contributions of this paper is indicating the usefulness of satellite imagery or remote sensing data in spatial-longitudinal studies. This research utilizes readily available LANDSAT images to recognize the decadal spatial growth from 1970 to 2000, and also in extension, calculate the BI (transformed NDVI) as a proxy for the intensity of development for the settlements. A series of regression models were run after processing the data, and the levels of significance were then studied and compared to see which relationships indicated the highest levels of significance. It was observed that the change in BI had a higher strength of relationships with the change in independent variables than the settlement area growth. Also, logarithmic and cubic models showed the highest R-Square values than any other tested models.

The identification and monitoring of informal settlements in urban areas is an important step in developing and implementing pro-poor urban policies. Understanding when, where and who lives inside informal settlements is critical to efforts to improve their resilience. This study aims at integrating OSM data and sentinel-2 imagery for classifying and monitoring the growth of informal settlements methods to map informal areas in Kampala (Uganda) and Dar es Salaam (Tanzania) and to monitor their growth in Kampala. Three building feature characteristics of size, shape and Distance to nearest Neighbour were derived and used to cluster and classify informal areas using Hotspot Cluster analysis and ML approach on OSM buildings data. The resultant informal regions in Kampala were used with Sentinel-2 image tiles to investigate the spatiotemporal changes in informal areas using Convolutional Neural Networks (CNNs). Results from Optimized Hot Spot Analysis and Random Forest Classification show that Informal regions can be mapped based on building outline characteristics. An accuracy of 90.3% was achieved when an optimally trained CNN was executed on a test set of 2019 satellite image tiles. Predictions of informality from new datasets for the years 2016 and 2017 provided promising results on combining different open source geospatial datasets to identify, classify and monitor informal settlements.

Updated spatial information on the dynamics of slums can be helpful to measure and evaluate the progress of urban upgrading projects and policies. Earlier studies have shown that remote sensing techniques, with the help of very-high resolution imagery, can play a significant role in detecting slums, and providing timely spatial information. The main objective of this thesis is to develop a reliable object-oriented slum identification technique that enables the provision of timely spatial information about slum settlements in Addis Ababa city. It compares the one-class support vector machines algorithm with the expert defined classification rule set in the discrimination of slums, using GeoEye-1 imagery. Two different approaches, called manual and automatic fine-tuning, were deployed to determine the best value of parameters in one-class support vector machines algorithm. The manual fine-tuning of the parameters is done using extensive manual trial. The automatic tuning is done using cross-validation grid search with the overall accuracy as the performance metric. Two regions of study were defined with different landscape compositions, providing different classification scenarios to compare the classification approaches. After image segmentation, twenty predictive variables were computed to characterize the objects in both study areas. An image analyst collected one hundred sample objects of a slum to be used as training for the single-class learner. In parallel, an image analyst has defined a hierarchical rule set to discriminate the class of interest. Results in both study areas indicate that the one-class support vector machine with manual tuning yields higher overall accuracy (97.7% in subset 1, and 92% in subset 2) and requiring much less application effort and computing time than the expert system.

This study explores the utilisation of spatial technologies as a tool to analyse and combat crime. The study deals specifically with remote sensing and its potential for being integrated with geographical information systems (GIS). The integrated spatial approach resulted in the understanding of land use class behaviour over time and its relationship to specific crime incidents per police precinct area. The incorporation of spatial technologies to test criminological theories in practice, such as the ecological theories of criminology, provides the science with strategic value. It proves the value of combining multi-disciplinary scientific fields to create a more advanced platform to understand land use behaviour and its relationship to crime. Crime in South Africa is a serious concern and it impacts negatively on so many lives. The fear of crime, the loss of life, the socio-economic impact of crime, etc. create the impression that the battle against crime has been lost. The limited knowledge base within the law enforcement agencies, limited logistical resources and low retention rate of critical staff all contribute to making the reduction of crime more difficult to achieve. A practical procedure of using remote sensing technology integrated with geographical information systems (GIS), overlaid with geo-coded crime data to provide a spatial technological basis to analyse and combat crime, is illustrated by a practical study of the Tshwane municipality area. The methodology applied in this study required multi-skilled resources incorporating GIS and the understanding of crime to integrate the diverse scientific fields into a consolidated process that can contribute to the combating of crime in general. The existence of informal settlement areas in South Africa stresses the socio-economic problems that need to be addressed as there is a clear correlation of land use data with serious crime incidents in these areas. The fact that no formal cadastre exists for these areas, combined with a great diversity in densification and growth of the periphery, makes analysis very difficult without remote sensing imagery. Revisits over time to assess changes in these areas in order to adapt policing strategies will create an improved information layer for responding to crime. Final computerised maps generated from remote sensing and GIS layers are not the only information that can be used to prevent and combat crime. An important recipe for ultimately successfully managing and controlling crime in South Africa is to strategically combine training of the law enforcement agencies in the use of spatial information with police science. The researcher concludes with the hope that this study will contribute to the improved utilisation of spatial technology to analyse and combat crime in South Africa. The ultimate vision is the expansion of the science of criminology by adding an advanced spatial technology module to its curriculum.
