Auf den Grünlandstandorten ist die Mutterkuh- und Schafhaltung sowie die Futterproduktion von Anwelksilage und Heu verbreitet. Weitere Grünlandflächen sind aber vorhanden, eine alternative Nutzungsform stellt die Jungrinder- und Färsenaufzucht dar. Im Rahmen dieser Arbeit wurde untersucht, inwieweit sich die Stall- bzw. Weidehaltung vom 15. bis zum 21.Lebensmonat von weiblichen Jungrindern auf das spätere Wachstum bis zum 100.Laktationstag der 1.Laktation, die Fruchtbarkeit, die Erkrankungen und Abgänge während der Aufzuchtphase, der 1.und 2.Laktation sowie die Milchleistung in den ersten beiden Laktationen auswirkt. Bis zum 14. und ab dem 22.Lebensmonat wurden beide Versuchsgruppen unter einheitlichen Stallbedingungen gehalten. In dem von Mai 2000 bis Dezember 2002 dauernden Versuch wurden zu Beginn nach zufäll-iger Auswahl jeweils 74 Jungrinder der Rasse Deutsche Holstein in die Stall- und Weide-gruppe eingeteilt. Die Untersuchungsergebnisse zeigen, dass im Vergleich zur Stallhaltung eine begrenzte Weidehaltung von Jungrindern zu einer deutlich geringeren Lebendmasseentwicklung a.p. Fruchtbarkeitsproblemen und größeren gesundheitlichen Risiken in der 1.Laktation führen. Mit der 2.Laktation konnten sich die Milchkühe aus der Weidegruppe stabilisieren und erreichten eine höhere Milchleistung, bessere Fruchtbarkeitsparameter und ein geringeres Abgangsgeschehen im Vergleich zu den Kühen aus der Stallgruppe. Die Weidenutzung kann das tierische Leistungspotential gut ausschöpfen, wenn eine ord-nungsgemäße Vorbereitung der Tiere an die Weidebedingungen erfolgt und ein zu hohes kompensatorisches Wachstum der Färsen nach der Weideperiode vermieden wird, um Probleme bei der Abkalbung und Spätfolgen in der Laktation zu verhindern. Folgende Optimierungsmaßnahmen der produktionstechnischen Bedingungen der Weidehalt-ung sind erforderlich: * Kontinuierliche Kontrolle der Lebendmasse und des Exterieurs der Weidetiere und gegebenenfalls Rückführung in die Stallhaltung * Verbesserung der Pflanzenstruktur des Grünlandes * Durchführung von regelmäßigen Pflegemaßnahmen auf dem Grünland / In the meadow land sites mother cow and sheep keeping as well as food production of wilted silage and hay is spread. Further pasture land areas are existing, an alternative form of use is the raising of young cattle and heifers. In the context of this dissertation is was examined to what extent there are effects of the cowshed and meadow keeping from the 15th up to the 21st month of life of female young cattle on the later growth up to the 100th day of the first lactation, the fertility, the illnesses and deaths during the period of raising, the first and second lactation as well as the milk results within the first two lactations. Up to the 14th and from the 22nd month of life both test groups were kept under the same cowshed conditions. At the beginning of the test from May 2000 up to December 2002 74 young cattle of the breed "Deutsche Holstein" were divided up into the cowshed as well as the pasture keeping by an accidental choice. The test results show that, in comparison to cowshed keeping, a limited pasture keeping of young cattle leads to a clearly lower liveweight development a.p., fertility problems and bigger health risks in the first lactation. With the second lactation the dairy cows could stabilize and reached a higher milk result, better fertility parameter and a lower death rate in comparison to the cows of the cowshed group. The use of the meadows can exhaust the animal potential well, if there is a proper preparation of the animals for the meadow conditions and if a compensatory growth of the heifers, that is too high, is avoided after the meadow period to prevent problems with the calving in the lactation. The following optimization measures of the production methods of the meadow keeping are necessary: * continuous checks of the liveweight and the appearance of the animals and if necessary return to the cowshed keeping * improvement of the plant structure of the pasture land * implementation of regular care measures on the pasture land

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The work, however displayed, comes to present a reflection about spaces of the city in the scope of the planning of the urban areas, specifically in the existing relation between the use of the land and the road system and of transports. The objective is to evaluate the reciprocity between these planning instances that they search to organize the city in its peculiarities, but that they must present a mutuality relation. The target of the work consists of the evaluation of an enterprise of great size, situated in the city of Uberlândia, Minas Gerais, with potential to generate interferences of great impact in its area of insertion as much in environmental terms as in the urban circulation that, in turn, also intervenes in the urban environment. It is reality of the great and medium urban centers the problems with congestion, traffic accidents, sonorous, visual and urban pollution what it generates, loses of time, energy, productivity and human resources. Of this form, great enterprises cause impacts in the transport system, in the immediate road system and in the neighborhoods it relative to its demand and, consequently, how much it offers of these infrastructures. The amplitude of the subject allows that it is opened to some questionings, being able to be explored by several meanings. Here, it will be argue, in specific, about the urban circulation and the systems of transport. One adopted methodologies proposals for Goldner, in 1994, exclusively, treating to shopping centers; of the Company of Engineering of Traffic CET, in 1983, and the National Department of Transports DENATRAN, 2001. For elaboration of the work and confirmation of the hypothesis above, it had been necessary data that characterize study area, about the city, the place of implantation of the enterprise and to the systems of transport and legislation about traffic generation and studies of impacts. It carried research in the place that allowed the characterization of the public of shopping and the attracted trips. The study of the variables that had contributed for the attraction of trips, the distribution of these displacements and the capacity of the road system, this last one, before and after implantation of shopping, they had also been analysis objects. The quantitative studies had been carried through by statistical calculation and of the software aaSidra 2.0. Of this form, one searched to contribute for the reflection about the necessity of studies of the use of the ground in the perspective of the urban circulation during the intervention in the city and the elaboration and quantification of interferences by studies of environmental and neighborhood impact. / O trabalho, ora exposto, vem apresentar uma reflexão sobre os espaços da cidade no âmbito do planejamento de áreas urbanas, especificamente na relação existente entre o uso do solo e o sistema viário e de transportes. O objetivo é avaliar a reciprocidade entre estas instâncias de planejamento que visam organizar a cidade em suas especificidades, mas que devem apresentar uma relação de mutualidade. O escopo do trabalho consiste na avaliação de um empreendimento de grande porte, situado na cidade de Uberlândia, Minas Gerais, com potencial de gerar interferências de grande impacto na sua área de inserção, tanto em termos ambientais como na circulação urbana que, por sua vez, também interfere no ambiente urbano. É realidade dos grandes e médios centros urbanos os problemas com congestionamento, acidentes de trânsito, poluição sonora, visual e do ar o que gera, perdas de tempo, energia, produtividade e recursos humanos. Assim, grandes empreendimentos são potenciais causadores de impactos no sistema de transporte, no sistema viário imediato e nas proximidades devido à sua demanda frente à oferta dessas infra-estruturas. A amplitude do assunto é passível de vários questionamentos, podendo ser explorado por meio de diversos vieses. Aqui foi avaliado, em específico, a circulação urbana e o sistema de transporte. Adotou-se metodologia proposta por Goldner, em 1994, tratando exclusivament e de shopping centers; da Companhia de Engenharia de Tráfego CET, de 1983 e do Departamento Nacional de Trânsito DENATRAN, em 2001. Para a elaboração do trabalho e confirmação da hipótese levantada, foram necessários dados que caracterizassem a área de estudo, no que se refere à cidade, ao local de implantação do empreendimento e aos sistemas de transporte, bem como legislação referente a Pólos Geradores de Tráfego e Estudos de Impacto. Realizou se pesquisa no local que permitiu a caracterização do púb lico do shopping e das viagens atraídas. O estudo das variáveis que contribuem para a geração de viagens ; a distribuição dos deslocamentos e a capacidade do sistema viário; essa última, antes e após implantação do shopping, também foram objetos de análise. Os estudos quantitativos foram realizados por meio de cálculo estatístico e do programa de avaliação aaSidra 2.0. Desta forma, buscou-se contribuir para a reflexão sobre a necessidade de estudos sobre o uso do solo na perspectiva da circulação urbana quando da intervenção na cidade e da avaliação e quantificação de interferências por meio de estudos de impacto ambiental e de vizinhança. / Mestre em Engenharia Civil

Uma das evidências para essa constatação é que ainda não há estudos suficientes sobre as dinâmicas ambientais e sociais do uso do solo, ocorrendo uma supervalorização da dimensão econômica na exploração dos mesmos. Objetivou-se realizar um estudo do meio físico, através de suas potencialidades e limitações, em sobreposição aos indicadores sócio-econômicos, com vistas a avaliar uma proposta metodológica de planejamento rural para o desenvolvimento sustentável. A partir daí procurou-se quantificar a adequabilidade do uso do solo dos municípios de Aguaí, Mogi Guaçú e Estiva Gerbi, Estado de São Paulo, para os anos de 1981, 1990 e 1997, compondo um banco de dados espaciais multitemporais. A avaliação sócio-econômica foi feita por meio da análise da dinâmica de ocupação e uso dos recursos naturais pelos agricultores, agrupados em setores censitários do IBGE, cujas variáveis e tipologia, georeferrenciadas, compuseram o banco de dados de atributos. A metodologia foi desenvolvida a partir da elaboração do Mapa de Adequabilidade do Uso do Solo dos municípios, empregando-se os Mapas de Aptidão Agrícola e de Uso e Cobertura do Solo, segundo o Método de Avaliação de Aptidão Agrícola, utilizando-se imagens dos satélites Landsat 2 (MSS) e Landsat 5 (TM). Foram também analisadas as transformações no uso dos solos pela tabulação cruzada e índices de exatidão global e Kappa, que indicam o grau de evolução nas mudanças ocorridas no espaço analisado. A caracterização sócio-econômica e tecnológica dos setores censitários foi efetivada por meio da Análise Fatorial de Correspondências Múltiplas (ACM) e da Classificação Hierárquica Ascendente, com os dados do Censo Agropecuário 1995/96. Os resultados da análise física multitemporal permitiram delimitar o histórico agroambiental do uso dos solos, representando a evolução e expansão agropecuária, em relação ao uso e adequabilidade dos mesmos. A análise espaço-temporal do uso intensivo do solo e da adequabilidade indicou uma forte evolução no sentido do aumento da ocupação dos solos, tanto para um uso adequado, quanto para uma sobreutilização. Nos três municípios, percebe-se que, com a intensificação da modernização da agricultura, as terras subutilizadas vão diminuindo, gradativamente de 1981 a 1997, apontando seu decréscimo na direção do desmatamento e/ou substituições das pastagens, para a introdução de culturas anuais e/ou permanentes, de maior valor comercial. Por outro lado, áreas que deveriam estar como reservas para preservação permanente acabam também sendo apropriadas por cultivos mais intensivos, ocorrendo, novamente, uma sobreutilização do solo. Foram definidos quatro tipos de agricultores nos municípios: modernos e diversificados citrícolas capitalizados, criadores descapitalizados de animais e familiares com produção vegetal diversificada. Como resultado final, obteve-se um conjunto de mapas, que traduzem o conhecimento integral dos espaços rurais e a ocupação do território. A metodologia proposta mostrou-se apropriada para o subsídio ao planejamento sócio-ambiental, propiciando elementos para um diagnóstico atualizado e eficaz, no estabelecimento de políticas públicas voltadas ao desenvolvimento rural sustentado / Abstract: The main problem raised in this thesis is that the occupation of the agricultural space for the farming, effectives production without the proper concern with the available natural resources, in special the ground, and without the knowledge of the social and economical characteristics of the producers. One of the causes for this confirmation is that it does not have enough studies yet on the environmental and social dynamic of the use of the land, occurring a supervaluation of the economic dimension in the exploration of agricultural ground. It was aimed to carry through a study of its potentialities and limitations, in overlapping to the social and economical index, with sights to evaluate a methodological proposal of agricultural planning for the sustainable development. Since then, it was tried to quantify the adequateness of the use of lands of the cities of Aguaí, Mogi Guaçú and Estiva Gerbi, State of São Paulo, for the years of 1981, 1990 and 1997, composing a multisecular space data base. The social and economical evaluation was made by the analysis of the dynamics of occupation and use of the natural resources for the agriculturists, grouped in tax sectors of the IBGE, whose georeferenced variable and typology had composed the bank of attributes. The methodology had as base the elaboration of the Map of Adequateness of the Use of Lands of the cities, using the Maps of Agricultural Aptitude and the Use and Covering of the Ground, according to Method of Classification of Agricultural Aptitude, using images of the satellites Landsat 2 (MSS), Landsat (5 TM) and Landsat 7 (ETM+). Also the transformations in the use of lands for the cross tabulation and index of global exactness and Kappa had been analyzed, that indicate the degree of evolution in the occured changes in the analyzed space. The social, economical and technological characterization of the tax sectors was accomplished by means of the Factorial Analysis of Correspondence (ACM) and the Ascending Hierarchic Classification, with the data of 1995/96 Farming Census. The results of the multisecular physical analysis had allowed to delimit the agro-environmental description of the use of the land, being represented the evolution and farming expansion in relation to the use and adequateness of lands. The analysis space-weather of the intensive use of the ground and the adequateness, indicated one strong evolution in the direction of the increase of the occupation of lands, as much for an adjusted use as for an over-use. In the three cities, it was perceived gradually that, with the intensification of the modernization of agriculture, the underutilized lands diminished, from 1981 to 1997, pointing its decrease in the direction of the deforestation and/or substitutions of the pastures with respect to the introduction of annual and/or permanent cultures of higher commercial value. On the other hand, lands that would have to remain as reserves for permanent preservation also finishing being appropriate for more intense cultivation, occurring, again, an over-use of the lands. Four types of agriculturists in the cities had been defined: modern and diversified, capitalized citrus producers, undercapitalized animal breeders, diversified familial vegetal production. As final result, a set of maps was gotten, aiming at the integral knowledge of the agricultural spaces and the occupation of the territory. The methodology proposal revealed appropriate for the subsidy to the spcial and environmental planning, propitiating elements for a fast, brought up to date and efficient diagnosis, in the establishment of directed public politics to the supported agricultural development / Doutorado / Planejamento e Desenvolvimento Rural Sustentável / Doutor em Engenharia Agrícola

The growing pressure on natural resources and biodiversity has led to a widespread acknowledgement of the services nature provides for humans. The appropriate representation of the benefits of sustainable land use in decision-making is still a challenge and tools that facilitate land use planning processes are needed. The dissertation presents a multicriteria assessment approach for a qualitative estimation of regional potentials to provide ecosystem services. This approach has been applied in several case studies in Saxony, Eastern Germany and Brasil. The ecosystem services concept builts the methodological framework for the assessment as it offers a universal approach to evaluate the impact of Land use/ Land cover change (LULCC) on human well-being. Since standardized methodical approaches for ecosystem services assessment at the landscape level are lacking, a particular requirement was to conceive a method that is easily transferable to other case study areas. Further the method should enable the use of existing and easily available environmental data, and it should be transparent for stakeholders and decision makers. The results of our study show that the combination of selected ecosystem services and land cover data such as CORINE Land Cover (CLC) can contribute to regional planning by communicating the effect of LULCC on ecosystem services, especially when applied as an evaluation basis in the tool GISCAME. The approach supports also the assessment of the performance of a region to provide ecosystem services and the comparison of regions towards this aspect. In the discussion section, the limitations of the developed approach are discussed. Main sources of uncertainty are related to coarse land cover data, lacking knowledge on the provision of ecosystem services at a landscape scale, and the difficulty to make relevant the ecosystem services concept in regional planning processes.

There is solved the cooperation of the land plan and complex land consolidation fot three different cadastral areas - Krtely, Malovičky and Podeřiště. These cadastral areas come under the administration of the community Malovice. The complex land consolidation and land plan were initiated in different order nad in defferent years. The land consolidatin for the cadastral area Krtely was initiated in 1992, for Malovičky in 2005 and for Podeřiště in 2007. Moreover, each project has been prepared by the different design office. The result of the diploma thesis is the assessment of the cooperation during different conditions and also the assessment of the processing quality of single projects.
