A pesquisa abordou o processo de uso e ocupação das terras nos municípios de Bodoquena, Bonito e Jardim, situados na borda leste do Parque Nacional da Serra da Bodoquena (PNSB), região sudoeste de Mato Grosso do Sul. Além disso, foi estudado o estado de conservação, em termos de estrutura e configuração da paisagem, dos remanescentes de cerrado e floresta contidos no interior do PNSB e em sua zona de amortecimento. O objetivo foi o de analisar a dinâmica de ocupaçao das terras nos municípios mencionados nos últimos 18 anos, com vistas à subsidiar estratégias de planejamento do uso e ocupação das terras ideal para a região. Objetivou-se também analisar a dinâmica espacial e temporal da paisagem que compõe o PNSB e sua zona de amortecimento, visando à conservação da biodiversidade local. Para isso, foi utilizado um sistema de informação geográfica (SIG) para elaboração de mapas temáticos e de um banco de dados georreferenciado. A determinação do grau de conservação do PNSB e da sua zona de amortecimento se deu mediante a utilização de métricas de paisagem, e da adoção dos preceitos da Teoria dos Grafos. O capítulo 1 demonstrou, por meio dos mapas gerados para os municípios de Bodoquena, Jardim e Bonito, dos anos de 1986 e 2004, que ocorreu uma perda de área nativa e um conseqüente crescimento da matriz antrópica composta por pastagens (principalmente) e culturas agrícolas. Apenas em Bodoquena os remanescentes vegetais tiveram maior porcentual que as áreas de pastagens e lavouras. Pode-se observar que a região estudada, passa por um processo de conversão de habitats naturais, outrora contínuos, para uma paisagem composta por fragmentos de cerrados, campos e florestas. O capítulo 2 mostrou que as fisionomias florestais e de cerrado, apresentaram-se em melhor estado de conservação em 1986 que em 2004. Além disso, foi possível observar que os remanescentes das formações vegetais acima citadas, apresentaram-se em melhor estado de conservação no interior do PNSB, que em sua zona de amortecimento. O mapa de relevância dos remanescentes de floresta, considerando as notas combinadas das métricas de forma e área das manchas indicou, quais são as áreas prioritárias para serem protegidas, por possuírem características adequadas para a persistência da biodiversidade florestal presente no PNSB e em sua zona de amortecimento. O setor norte se destacou por apresentar remanescentes com valores alto e extremamente alto com relação à relevância. O mesmo setor norte possui um maior número de pontos de sensibilidade à quebra de conectividade entre as manchas de floresta. Nesta região pode-se observar que a maior parte dos pontos com alta sensibilidade, merece alguma estratégia que retarde ou mesmo cesse o processo de conversão da floresta para pastagem ou agricultura. Com relação ao padrão de fragmentação dos remanescentes vegetais, conclui-se o seguinte: os remanescentes de cerrado e floresta, no intervalo de dezoito anos, ficaram menores, mais irregulares, mais distantes e mais numerosos, indicando uma piora no estado de conservação da paisagem entre 1986 e 2004. Isso compromete a manutenção da biodiversidade, a persistência de espécies, diminuindo suas populações mínimas viáveis. A diversificação das formas de uso das terras na matriz é recomendada, com a introdução da silvicultura (principalmente composta por espécies nativas), por exemplo, também poderá auxiliar na manutenção/surgimento da heterogeneidade espacial e da complexidade estrutural da paisagem. A Teoria dos Grafos, avaliada neste trabalho, apresentou-se como ferramenta eficiente para se calcular a conectividade em paisagens heterogêneas. / The research approached the process of use and occupation of lands in the cities of Bonito, Bodoquena and Jardim, situated in the edge east of the National Park of the Serra da Bodoquena (NPSB), southwestern region of Mato Grosso do Sul, Brazil. Moreover, the conservation state was studied, in terms of structure and configuration of the landscape, of the contained remainders of cerrado and forest in the interior of the NPSB and its buffer zone. The objective was to analyze the dynamics of occupation of lands in the cities mentioned in last the 18 years, with sights to subsidizing strategies of planning of the use and ideal occupation for the region. Also, it was objectified to analyze the space-temporal dynamics of the landscape that composes the PNSB and its buffer zone, aiming at to the conservation of local biodiversity. For this, geographic information system (GIS) for the classification of images of satellite and elaboration of thematic maps was used. The determination of the NPSB conservation degree and its buffer zone occurred by means of the use and of metrics of landscape ecology and the adoption of Graph Theory. Chapter 1 demonstrated, by the maps generated for the cities of Bonito, Bodoquena and Jardim, of the years of 1986 and 2004, that it occurred a loss of native area and a consequent growth of the composed matrix for pastures (mainly) and agriculture. Only in Bodoquena the vegetal remainders had percentual had been bigger than the areas of pastures and agriculture. It can be observed that the studied region passes for a process of conversion of natural habitats, long ago continuous, for a composed landscape for patches of cerrado and forests in a matrix predominantly represented by planted pasture and agriculture. Chapter 2 showed that the forest and cerrado physiognomy, had been presented in better conservation in 1986 that in 2004. Moreover, it was possible to observe that the remainders of the vegetal formations above cited, had been presented in better conservation in the interior of the NPSB, that in its buffer zone. The map of relevance of the remainders of forest, considering the agreed area and shape notes metric of the spots, had indicated which the priority areas to be protecting, for possessing characteristics adjusted for the persistence of present forest biodiversity in the NPSB and its buffer zone. The north sector had detached for presenting remainders with high and extremely high values to the relevance. The same north sector posses a bigger number of points of sensitivity to the break of connectivity between the forest spots. In this region it can be observed that most of the points with high sensitivity deserves some strategy that delays or stop the conversion process of the forest for pasture or agriculture. Regard the standard of spelling of the vegetal remainders, had been concluded that: the remainders of cerrado and forest, in the interval of eighteen years, had been lesser, more irregular, more distant and more numerous, indicating a worsening in the state of conservation of the landscape between 1986 and 2004. This compromises the maintenance of biodiversity, the species persistence, diminishing its viable minimum populations. The diversification of the forms of use of lands in the matrix is recommended, with the introduction of forestry (mainly composed for native species), for example, also it will be able to assist in the maintenance/sprouting of the space heterogeneity and the structural complexity of the landscape. The Graph Theory, evaluated in this work, was presented as efficient tool to calculate the connectivity in heterogeneous landscapes.

Convencido que el desconocimiento de la historia y de nuestro entorno, nos conduce a resolver por caminos que restan y no aportan; olvidando que la naturaleza provee; más no castiga. El siguiente proyecto de tesis; ``Museo de los Fenómenos Naturales – Malecón Rivera Monserrate``, es una investigación arquitectónica que pretende unir las tipologías de museo y malecón. El proyecto busca ser un ejemplo de la prevención del ``desastre``, tanto por las exposiciones que no pretenden una falsa ecología, zonas de investigación y por sobretodo la volumetría. Esta última, contempla relacionarse conteniendo las crecidas del río Rímac, sin imponerse ni al entorno natural ni al contexto urbanístico histórico de la ciudad de Lima. Para ello utilizará elementos constructivos, como la tajamar, techos caminables y equipamientos como huertos inundables. La idea de utilizar elementos y conceptos constructivos, hoy olvidados; se basa en el uso de tres énfasis; Determinismo ambiental, Edificaciones calendario y Ciclos de retroalimentación. El solar para desarrollar el proyecto, está ubicado en la zona abandonada de la estación Monserrate, Cercado de Lima. La selección del terreno se fortalece con dos planes Municipales; La iniciativa de recuperación de la plaza Monserrate y la restauración de viviendas patrimoniales Lima 2035. El proyecto pretende ser una opción viable tras el desarrollo de Lima 2035. / Convinced that the ignorance of history and our environment, leads us to resolve by paths that remain and do not contribute; forgetting that nature provides; more does not punish. The following thesis project; `` Museum of Natural Phenomena - Malecón Rivera Monserrate '', is an architectural investigation that aims to unite the typologies of museum and boardwalk. The project seeks to be an example of the prevention of the `` disaster '', both for the exhibitions that do not pretend a false ecology, research areas and above all the volumetry. The latter, contemplates relating by containing the floods of the Rímac river, without imposing either the natural environment or the historical urban context of the city of Lima. For this, it will use construction elements, such as the cutwater, walkable roofs and equipment such as flooded orchards. The idea of using elements and constructive concepts, today forgotten; it is based on the use of three emphases; Environmental determinism, Calendar buildings and Feedback loops. The site to develop the project is located in the abandoned area of the Monserrate station, Cercado de Lima. The selection of the land is strengthened with two Municipal plans; The initiative for the recovery of Plaza Monserrate and the restoration of Lima 2035 heritage homes. The project aims to be a viable option after the development of Lima 2035. / Tesis

Community-based natural resource management (CBNRM) related to protected areas (PAs) originated in the 1980’s in Zimbabwe, Africa, in the buffer zone communities of Africa’s National Parks. CBNRM attempted to address the problems associated with colonial, protectionist style ‘fence and guns’ conservation management approaches, which excluded resource-based communities from conservation areas. CBNRM attempts to meet the biodiversity conservation objectives of conservation areas, and the sustainable development and livelihood objectives of neighbouring communities. While CBNRM initiatives have been well documented internationally over the past decades, little is known about the status of CBNRM within Canada. In order to bridge this knowledge gap and to link trends in conservation and protected areas management internationally to Canada and to British Columbia (BC), this thesis examines the potential for community-based natural resource management (CBNRM) affiliated with BC's Protected Area System. “Potential” is determined by comparing the situation in BC to the international CBNRM experience. The study draws on a sample of Conservancies from the categories of the BC Protected Area (PA) System, focusing particularly on the nine Sea-to-Sky Land and Resource Management Plan (LRMP) Area Conservancies and neighbouring First Nations communities: Squamish, L’il’wat and In-SHUCK-ch. Information has been obtained through interviews (guided by semi-structured questionnaires) conducted with BC government informants and First Nations representatives, supplemented by key documents. The questionnaire examined the potential for CBNRM according to a.) the community's perspective: potential (costs and) benefits of the protected area, including goods and services, cultural and social benefits and sustainable economic development opportunities provided by the protected area; and benefits of community involvement in natural resource management and protected area governance; and b.) the conservation perspective: benefits through community cooperation in biodiversity conservation within the targeted protected area. Other factors that have been identified through the international experience to affect CBNRM initiatives, such as use regulation; tenure; policies and legislation; awareness of and support for the protected area; and community capacity were thoroughly examined across all sources of information. This study finds that there is potential for CBNRM affiliated with the BC PA system in protected area designations such as ‘Conservancies’. Potential relates to the role of CBNRM in biodiversity conservation, meeting the aspirations of BC’s First Nations communities, and in recognizing First Nations as legitimate stakeholders in protected areas and conservation management. As in the international experience, numerous social, political, economic and other factors present opportunities and challenges to the adoption of CBNRM in BC. This thesis concludes with key recommendations for protected areas and conservation management in BC and Canada and identifies opportunities to further explore key topic areas that arose from the research findings.

MENVSC / Department of Ecology and Resource Management / The purpose of this study was to evaluate the strategic management of the Thohoyandou Block J landfill site. There are limited documented materials on strategic management of landfill sites in South Africa. As a result, this study sought to close this gap and expose new insights that it deemed to be of great importance in the management and operations of landfill sites. The capacity of a TBJ landfill site in terms of its efficiency in disposing waste, adherence to rules and procedures and the overall management of the site are the key areas of this study. The dominant types and sources of solid waste disposed at the TBJ landfill site, efficiency and effectiveness of operation of TBJ landfill site and operational challenges are the main areas covered in this study. The study adopted the mixed methods approach, involving both qualitative and quantitative research methods. Both primary and secondary data were acquired. Primary data were obtained through a questionnaire, an interview and field observation, using an observation checklist. Secondary data were obtained from ArcGIS Desktop Help 9.2 and documented materials from the Thulamela Local Municipality and the TBJ landfill site, the Integrated Waste Management Plan, Integrated Development Plan, TBJ landfill site’s monthly report, audit report and landfill site’s operating plan. Basically, field observation and a questionnaire completed by the waste manager, landfill operator and supervisor, were used to collect data on the operational challenges of TBJ landfill site and to obtain data on the efficiency and effectiveness at which the TBJ landfill site is operating. Waste pickers were interviewed and field observation was undertaken, to identify the dominant types and sources of waste disposed at the TBJ landfill site. A questionnaire completed by TBJ landfill operator, ArcGIS Desktop Help 9.2 for field measurement, reports of the amount of waste recorded and the municipality’s database, were utilized to elicit data regarding the determination of the capacity of TBJ landfill site. The results obtained revealed that the TBJ landfill site’s remaining capacity is 317 085 m3, which will be exhausted in the next 4 years. Plastics were found to be the dominant waste disposed at the TBJ landfill site, at 40%, followed by card-boxes, which constituted 32%. The dominant sources of solid waste generation in the TBJ landfill site were households, at 51%, followed by commercial, at 31% and industrial, at 11%. The absence of a weighbridge, to weigh loads of waste, frequent break down of equipment, lack of equipment required to operate the TBJ landfill site efficiently and the presence of fire hazards, were some of the / NRF

The subject of the Diploma thesis is an urban study in the area of the former part of Tepna in Náchod. The Tepna area is largely after demolition and is currently dilapidating. This area has the potential for development and use, located within a short walking distance from the historic city center and at the same time from the residential area in the northern part of Náchod. Above the solved area is the castle, which is a dominant and a city landmark. The aim of the proposal was to use the potential of the territory at most, but at the same time to approach the surrounding landscape sensitively and to connect the urban character of the surrounding urban structure of the city and, conversely, the existing buildings of unclosed blocks are supplemented by new development.

R É S U M É<p><p>I. Actuellement, en Afrique sub-saharienne, les acteurs de la conservation considèrent que la<p>survie à long terme de la faune sauvage ne peut être assurée que par le maintien de son habitat<p>en dehors des aires de conservation intégrale. Dans cette optique, les projets de conservation<p>tentent de préserver des étendues de végétation naturelle au sein de « zones tampons » ou de<p>« corridors de migration » dans la périphérie des aires protégées. Cette thèse s’est intéressée aux possibilités de conserver de tels espaces en concertation avec les populations riveraines du parc national de Zakouma, une aire protégée du Sud-est du Tchad. Notre objectif a été de rechercher des solutions aux problèmes que rencontrent généralement les aménagistes dans cette action. Notre hypothèse est que l’aménagement des périphéries d’aires protégées doit s’appuyer sur une meilleure identification des déterminants locaux de l’exploitation des espaces de végétation naturelle, et que leur analyse doit s’appuyer sur une approche spatiale.<p>II. Plusieurs étapes de recherches ont permis d’alimenter notre réflexion :<p>Une première phase de terrain a été tout d’abord été menée à Am Choka, un village représentatif de la zone la plus densément peuplée de la périphérie est du PNZ. Les objectifs visés étaient i.) d’une part, de déterminer les activités humaines affectant le plus le paysage<p>végétal naturel de la périphérie du parc, et donc susceptibles d’annihiler son rôle de « zone<p>tampon », et ii) d’autre part, d’identifier les savoir-faire et les facteurs socioéconomiques et<p>politiques qui régissent l’exploitation des espaces de végétation naturelle. Outre l’observation participante au village, des cartographies fines du terroir et des zones d’exploitation, ainsi que des entretiens semi-structurés ont été réalisés sur le terrain.<p>La seconde phase de recherche a été consacrée à la réalisation d’un outil cartographique dans<p>le but (i) d’évaluer l’état de la zone périphérique en terme de répartition et d’occupation relative des diverses formations végétales naturelles par rapport à l’emprise agricole, et ii.) d’en déduire les zones de la périphérie les plus susceptibles de faire l’objet d’un processus de gestion des espaces de végétation naturelle. A cet effet, quatre images satellites récentes ont été acquises. Les opérations de terrain ont donné lieu à 234 relevés sur ligneux et 2440 relevés qualitatifs d’autres types d’occupation du sol. Ces relevés ont été utilisés pour l’interprétation des scènes satellites en unités cartographiques.<p>La troisième phase de recherche a porté sur une analyse du dispositif d’aménagement récemment proposé pour la zone périphérique du PNZ par le projet gestionnaire du parc. Notre objectif était de mettre en évidence, les modalités réelles de prise en compte de l’organisation locale de l’exploitation ou de la gestion des espaces de végétation naturelle, et de les confronter avec les connaissances acquises lors de la première phase de recherche. <p>III. La recherche aboutit aux résultats suivants :<p>Les populations rurales ont une bonne connaissance du milieu physique et utilisent une<p>typologie qui leur permet de localiser les différentes composantes de leur terroir et de leur<p>finage, et d’en évaluer le potentiel.<p>La défriche des espaces de végétation naturelle à des fins agricoles est régie par des instances<p>coutumières villageoises et cantonale qui exercent un fort pouvoir en matière de gestion du<p>foncier et de planifications agricoles.<p>La culture du sorgho repiqué (berbéré - Sorghum bicolor) constitue la principale source de<p>réduction des espaces de végétation naturelle. Elle modifie le paysage sur de grandes portions<p>de territoire car sa mise en place nécessite un essartage intégral des savanes à Acacia seyal.<p>L’accès et l’usage des espaces de végétation naturelle pour la collecte de produits forestiers<p>ligneux et non-ligneux sont libres et non liés à la propriété foncière. L’exploitation de ces<p>produits n’entraîne pas de coupe à blanc mais les contraintes d’exploitation conditionne l’étendue spatiale du finage autour d’un village donné. Certaines zones du finage sont cependant l’objet de bornages fonciers en vue de projets agricoles à plus ou moins long terme. Les travaux cartographiques ont abouti à l’appréciation de l’étendue et de répartition des formations végétales naturelles. Le sorgho de décrue occupe un peu moins de 5% de la totalité de la superficie de zone périphérique. Les zones de cultures sont concentrées pour l’essentiel à<p>l’est et au nord de l’aire protégée. Un dixième de la superficie d’origine des savanes à Acacia<p>seyal a déjà été exploité à des fins agricoles. Cette carte peut être exploitée pour localiser les<p>zones d’enjeux entre conservation et développement économique. Cet exercice permet de<p>reconsidérer la délimitation en zones de protection de la périphérie.<p>Dans sa formulation, le « plan de gestion » témoigne largement d’une volonté d’associer les<p>populations riveraines à l’aménagement de la périphérie du parc. Cette collaboration sera<p>certainement entravée par l’absence de compensation en contrepartie de la limitation du<p>développement agricole au profit de l’habitat de la faune sauvage. Par contre, elle pourrait<p>être favorisée si le zonage proposé correspondait aux limites des terroirs et des finages. Un<p>préliminaire à tout processus de gestion concertée des espaces de végétation naturelle est aussi l’identification des décideurs qui ont autorité sur ces espaces. L’étude débouche sur suggestions permettant aux aménagistes leurs permettant d’atteindre leurs objectifs de conservation de la faune et de son habitat en concertation avec les populations riveraines. Ces recommandations peuvent certainement être adaptées à d’autres contextes d’aménagement des périphéries d’aires protégées. <p><p><p>ABSTRACT<p>I. Nowadays, in Sub-Saharan Africa, conservation actors believe that the long-term survival<p>of wild animals can be ensured only through the maintenance of their habitat outside areas of<p>total conservation. Accordingly, conservation projects seek to preserve areas of natural<p>vegetation in “buffer zones” or “migration corridors” on the periphery of protected areas.<p>The present doctoral thesis studies the possibilities of conservating such areas in concertation<p>with the populations living around Zakouma National Park (ZNP), a protected area in southeast<p>Chad. Our aim has been to find solutions to the problems generally encountered by forest<p>managers working towards this goal. Our hypothesis is that the management of surroundings<p>of protected areas must be grounded on a better identification of the local factors determining<p>the exploitation of natural vegetation areas, and that any analysis must be based on a spatial<p>approach.<p>II. Several steps in the research provided grounds for reflection:<p>As a first phase, a survey was conducted in Am Choka, a village representative of the most<p>densely populated zone of the eastern periphery of ZNP. The objectives were (i) to determine<p>which human activities most affect the natural vegetal landscape of the periphery of the park<p>and hence are likely to annul its role of “buffer zone”, and (ii) to identify which know-how<p>and socio-economic or political factors govern the exploitation of natural vegetation areas. In<p>addition to participatory observation in the village, detailed maps were made of the ‘terroir’<p>and the ‘finage’ (the total area exploited by a village), and semi-structured interviews were<p>conducted on the spot.<p>The second phase of research was dedicated to the creation of a cartographic tool with the<p>intention of (i) assessing the state of the peripheral zone in terms of where and to what extent<p>the natural vegetal formations are situated in comparison with the land under cultivation, and<p>(ii) pinpointing the peripheral zones best suited to a process of management of natural<p>vegetation areas. To that end, four recent satellite pictures were acquired. Operations on the<p>ground yielded 234 plottings over wood stands and 2 440 qualitative plottings of other types<p>of land occupation. These plottings were used to convert the satellite images into cartographic<p>units.<p>The third phase of research was concerned with an analysis of the management mechanism<p>recently proposed for the peripheral zone of ZNP by the park management project. Our aim<p>was to bring to the fore the actual methods by which the local organisation of exploitation or<p>management of the natural vegetation areas is taken into account and to compare them with<p>the knowledge acquired under the first phase of research.<p>III. The research produced the following results:<p>The rural populations have a good knowledge of the physical environment and use a typology<p>which enables them to localise the different components of the terroir and of the finage, and<p>to assess their potential.<p>The clearing of areas of natural vegetation for agricultural purposes is governed by traditional<p>village or canton authorities, which exert a powerful influence over land management and<p>agricultural planning.<p>The cultivation of transplanted sorghum (berbéré - Sorghum bicolor) is the main source of<p>reduction of areas with natural vegetation. It modifies the landscape over large swathes of<p>territory inasmuch as this cultivation method leads to a total clearing of the Acacia seyal<p>savannas. Access to and use of areas of natural vegetation for collecting wood and non-wood forest<p>products are free and not linked to land ownership. Exploiting these products does not lead to clear-cutting of the forest, but the constraints of exploitation influence the spatial extent of the finage around a given village. Some zones of finage are nevertheless subjected to land<p>boundary markings when agricultural projects are planned in the shorter or longer term.<p>The cartographic findings led to an assessment of the area covered by, and the distribution of,<p>natural vegetal formations. Flood-irrigated sorghum occupies just under 5% of the total area<p>of the periphery. The cultivation zones are mostly concentrated east and north of the protected area. One tenth of the original area of Acacia seyal savannas has already been exploited for agriculture. The map can also be used to identify areas caught between conservation and<p>economic development. This exercise makes its possible to reconsider the delimitation of the<p>periphery into protection zones. In its formulation, the “management plan” largely reveals the will to involve local populations<p>in the management of the periphery of the park. This collaboration will certainly be hampered<p>by the absence of compensation to offset any limitation of agricultural development to the<p>benefit of the wild animal habitat. It could, however, be promoted if the proposed zoning were<p>to correspond to the limits of the terroirs and finages. A preliminary to any process of<p>concerted management of the areas of natural vegetation would also be to identify the<p>decision-makers who have authority over these expanses. The present study throws up suggestions as to how forest managers might attain their<p>objectives for the conservation of fauna and their habitat in concertation with the local<p>populations. These recommendations can certainly also be extrapolated to other contexts of<p>management of the peripheries of protected areas. / Doctorat en Sciences agronomiques et ingénierie biologique / info:eu-repo/semantics/nonPublished
