Orientador: Andréa Aparecida Zacharias / Resumo: Na atualidade, uma série de desastres inter-relacionados ganharam notoriedade no Brasil e no mundo, reunindo episódios que marcaram crescentes perdas, humanas e econômicas, associadas aos riscos e suas consequências. O processo de urbanização, juntamente com a impermeabilização do solo, retificação e assentamento em cursos d’água e encostas, contribuíram para o aumento do impacto de inundações, enchentes e vários outros processos advindos da ação antrópica que levam ao risco socioambiental. Somam-se nas últimas cinco décadas mais de dez mil mortes em desastres naturais no Brasil, a maioria destes relacionadas a inundações e queda de encostas. A magnitude de um desastre está vinculada com os fenômenos sociais, econômicos e demográficos, entre outros, e contribuem para aumentar a vulnerabilidade e exposição da população. O recorte espacial aqui analisado compreende a Região Administrativa do Lavapés, macrozona que envolve a área urbana do município de Bragança Paulista/SP. Bragança Paulista sofre, historicamente, uma série de problemas socioeconômicos e ambientais. Destaca-se o aumento na magnitude e frequência das enchentes devido à extensa cobertura impermeabilizada, pois grande parte da água que antes era infiltrada no solo, passa então a compor o volume que escoa superficialmente. O objetivo principal desta pesquisa funda-se sobre o estudo da espacialidade da vulnerabilidade socioambiental aos riscos hidrológicos, em específico as inundações, considerando a atuação dos fato...

The urbanization process, along with degree of saturation, soil imperviousness, rectification and improper settlement on hillslopes and near to the rivers, have contributed to an increasing impact of floods and several human-induced processes that lead to socio-environmental risk. In the last five decades, there have been more than ten thousand deaths caused by natural disasters, most of them related to floods and landslide. The magnitude of a disaster is related to social, economic and demographic phenomena, among others, and contributes to increasing the population's vulnerability and exposure. We analyzed the Lavapés Administrative Region, a macrozone encompassing the urban area of Bragança Paulista/SP municipality. The city of Bragança Paulista have suffered, historically, a plenty of socioeconomic and environmental issues. The increasing intensity and frequency of the floods are noteworthy due to extensive impervious cover, since large water volumes that were previously infiltrating, now become part of the surface runoff. The main objective here relies on the spatial distribution of socio-environmental vulnerability related to hydrological risks, particularly floods, considering the triggering factors in urban areas. The methodological procedures are... (Complete abstract click electronic access below) / Mestre

Weltweit ist die Nutzung von Land häufig umstritten. Ob Bergbau, Nationalparks, Forstwirtschaft oder neue Wohngebiete: Landnutzungskonflikte sind allgegenwärtig, können äußerst schädlich sein und werden in Zukunft noch bedeutender werden. Die Dissertation hebt daher Landnutzungskonflikte als eines der Schlüsselthemen sowohl der aktuellen als auch der zukünftigen Landnutzungspraxis hervor. Die Entwicklung geeigneter Strategien zum Umgang mit diesen Konflikten, basierend auf einem fundierten Verständnis ihrer Eigenschaften, zählt zu den dringlichsten Aufgaben für Politik, Planung und Landmanagement. In der aktuellen Forschungsliteratur gibt es jedoch drei wesentliche Herausforderungen, die die Entwicklung adäquater Ansätze zum Umgang mit Landnutzungskonflikten behindern: Erstens der Stand des Forschungsfeldes, das zwar umfangreich, aber fragmentiert und daher schwer zu überblicken ist; zweitens der fehlende Überblick über die in der Praxis auftretenden Landnutzungskonflikte; und drittens die bislang unzureichende Forschung zu Konfliktverläufen. Um diese Lücken zu schließen, wurde eine Literaturanalyse mit einer empirischen Studie in zwei Regionen Nordostdeutschlands kombiniert: den Stadt-Umland-Räumen von Schwerin in Mecklenburg-Vorpommern und Cottbus in Brandenburg. Mithilfe eines induktiven Ansatzes, der eine Literaturrecherche, eine Situationsanalyse und eine Analyse der Konfliktverläufe umfasst, liefert die Dissertation neue Einblicke in die Eigenschaften und Verläufe von Landnutzungskonflikten, die Akteuren aus Politik, Planung und Landnutzungspraxis helfen können, die Konflikte zu identifizieren, die angegangen werden müssen, und kollaborative Konfliktverläufe zu fördern. Sie präsentiert somit neue Strategien zur Schaffung agonistischer Arenen für die Aushandlung unterschiedlicher Landnutzungsinteressen. Die Dissertation schließt mit einer Diskussion der Grenzen der vorliegenden Ergebnisse sowie vielversprechender Ansätze für die weitere Forschung. / Across the globe, land use is frequently contested. From mining to national parks, from forestry to new housing estates: Land use conflicts are ubiquitous, they can be highly detrimental, and they are likely to become even more significant in the future. The dissertation therefore highlights land use conflicts as one of the key issues in both current and future land use practice, and the development of appropriate strategies to address land use conflicts, based on a thorough understanding of their nature, as one of the most pressing challenges in land use policy, planning, and management. However, there are three key challenges in the current literature that hinder the development of adequate approaches to dealing with land use conflicts: First, the state of the research field, which is vast but fragmented and thus difficult to gain an overview of, second, the lack of overview of the land use conflicts that occur in land use practice, and third, insufficient research on land use conflicts’ dynamics, which makes it difficult to adequately handle ongoing conflicts. To address these gaps, the dissertation combines literature analysis and an empirical study of land use conflicts in two urban-rural fringe regions in north-east Germany: the urban-rural fringes of Schwerin in Mecklenburg-Western Pomerania and Cottbus in Brandenburg. Employing an inductive approach that includes a literature review, a situation analysis, and an analysis of conflict dynamics, the dissertation provides new insights into the nature and dynamics of land use conflicts that can help policy-makers, planners, and land users to identify those (types of) land use conflicts that need to be addressed, and to foster collaborative conflict dynamics. It thus presents novel strategies to create agonistic arenas for the negotiation of divergent land use interests. The dissertation closes by discussing the limits of the present results as well as promising trajectories for future research.
