O conceito de resiliência urbana colabora nas discussões de como as cidades podem se preparar ou se adaptar para lidar com desastres naturais num contexto de eventos extremos. Resiliência urbana entende-se enquanto processo que envolve capacidades de aprendizado e adaptação com vistas à redução do risco de desastres naturais, ao retorno às funções desejadas e à melhoria da qualidade de vida das pessoas. Os escorregamentos configuram um dos desastres que mais causaram mortes no município de Santos, no litoral do Estado de São Paulo; no entanto, o número de vítimas fatais reduziu-se significativamente após a implementação do Plano Preventivo de Defesa Civil (PPDC) operado anualmente desde 1989. Entendendo que a Defesa Civil municipal é a instituição que lida diretamente com a questão dos desastres, o objetivo desta pesquisa foi identificar os instrumentos relativos à gestão de risco de escorregamentos utilizados pela Defesa Civil de Santos e analisar a aplicação dos mesmos na promoção da resiliência urbana. A partir de uma pesquisa qualitativa que envolveu revisão bibliográfica, pesquisa documental e pesquisa de campo, identificaram-se os seguintes instrumentos: Monitoramento Meteorológico; Carta de Suscetibilidade a Movimentos Gravitacionais de Massa e Inundações, Plano Municipal de Redução de Riscos e Carta Geotécnica Morros de Santos e São Vicente. Concluiu-se que a promoção da resiliência urbana pela Defesa Civil de Santos ocorre parcialmente, pois os instrumentos ainda estão em processo de implementação e desafios precisam ser superados como a articulação das secretarias municipais em prol da redução de risco. / The concept of urban resilience has entered discussions of how cities can prepare, adapt and deal with natural disasters in a context of extreme events. Urban resilience is understood as a process that involves learning and adaptation capabilities in order to reduce the risk of disasters, restore desired functions and improve quality of life. Landslides constitute one of the disasters that caused more deaths in the municipality of Santos (the São Paulo state coast), however, the number of fatalities dropped significantly after the implementation of the Civil Defense Preventive Plan (PPDC) operated annually since 1989. Taking into consideration that the municipal civil defense is the institution that deals directly with the issue of disasters, the aim of this research was to identify the instruments concerning the landslide risk management used by the Civil Defense and analyze their application in promoting urban resilience. From qualitative research including literature reviews, as well as document research and field research, the following instruments were identified: weather monitoring; a chart mapping susceptibility to gravitational mass movements and floods, a risk reduction plan and a geotechnical aptitude to an urbanization chart. In conclusion, the promotion of urban resilience by the Civil Defense of Santos is partially because the instruments are still in the implementation process and challenges need to be overcome as the articulation of municipal departments in favor of risk reduction.

A presente dissertação tem por objetivo discutir a importância de uma postura resiliente para a busca do urbanismo sustentável. O termo \"sustentável\" e suas variantes passaram por um desgaste nas últimas décadas, formando uma barreira prejudicial à sua aplicação efetiva. A \"resiliência\", surge, então, como uma forma de revisitar a questão, através de um conceito oriundo da física, que possibilita conceber uma transposição teórica para a arquitetura e o urbanismo, disciplinas nas quais o tema pode colaborar na formulação de novas ferramentas e conceitos aplicáveis ao planejamento e projeto. Almeja-se, através da sua conceituação teórica, contribuir para a elaboração de uma postura resiliente e promover o termo \"resiliência urbana\" em direção ao enfrentamento da crise urbana, ocasionada pelo crescimento vertiginoso da urbanização mundial e da consequente aglomeração populacional nas cidades. Nos países em desenvolvimento, essa abordagem pode ser de grande utilidade, dado que a crise urbana é fortalecida pelo avanço da informalidade e pela formação de novos tecidos urbanos às margens do planejamento. O conceito de resiliência, neste caso, possibilita uma discussão voltada às questões de espontaneidade, improvisos, constantes mudanças e transformações, inerentes à condição urbana, se discutido dentro de uma abordagem de Sistemas Adaptativos Complexos. Para tanto, elaborou-se uma análise reflexiva, a fim de aferir a transferência da teoria para prática, a partir de três projetos urbanos já implantados: as intervenções em torno da Línea K, em Medellín, Colômbia, o sistema teleférico do Complexo do Alemão e o Parque Sitiê, ambos na cidade do Rio de Janeiro. A partir daí, pôde-se constatar que a visão sistêmica adaptativa e complexa da resiliência traz a possibilidade de promover a inter-relação entre sociedade, economia e ambiente na construção do meio urbano e, assim, encorajar uma nova postura frente a difusão de um Urbanismo Sustentável. / The present dissertation aims to discuss the importance of a resilient posture in the search for a sustainable urbanism. The term \"sustainable\" and its variants have gone through a wear and tear through the last few decades, forming a barrier which prejudices its effective application. The \"resilience\" term then appears as a way of revisiting this matter, through a concept derived from physics, that allows a theoretical transposition to architecture and urbanism disciplines in which the subject can cooperate in the formulation of new tools and concepts that can be applied into planning and project design process. Over the theoretical conception, it is intended the contribution on the elaboration of a resilient attitude and therefore promotes the term \"urban resilience\" towards the current urban crisis, caused by the dramatical growth of the world urbanization and the consequent population cluster within cities. In developing countries, the approach can be very useful, given that the urban crisis is strengthened by the rise of informality and the formation of new urban networks at the edge of planning actions. The concept of resilience, in this case, enables a discussion focused on spontaneity issues, improvisations, changes and transformations, inherent to the urban condition, discussed within a Complex Adaptive Systems approach. However to elaborate a reflexive analysis it is necessary to verify the transformation of theory into practice from three urban projects already implemented: Line K\'s urban interventions in Medellín, Colombia, cable car system at Alemão Complex and Sitiê Park, both in Rio de Janeiro, Brazil. In conclusion, an adaptive and complex systemic view of resilience has the potential to promote an interrelationship between society, economy and environment during the construction of an urban environment and therefore encourage a new attitude towards the diffusion of Sustainable Urbanism.

abstract: Cities are in need of radical knowledge system innovations and designs in the age of the Anthropocene. Cities are complex sites of interactions across social, ecological, and technological dimensions. Cities are also experiencing rapidly changing and intractable environmental conditions. Given uncertain and incomplete knowledge of both future environmental conditions and the outcomes of urban resilience efforts, today’s knowledge systems are unequipped to generate the knowledge and wisdom needed to act. As such, cities must modernize the knowledge infrastructure underpinning today’s complex urban systems. The principal objective of this dissertation is to make the case for, and guide, the vital knowledge system innovations that coastal cities need in order to build more resilient urban futures. Chapter 2 demonstrates the use of knowledge systems analysis as a tool to stress-test and upgrade the Federal Emergency Management Agency flood mapping knowledge system that drives flood resilience planning and decision-making in New York City. In Chapter 3, a conceptual framework is constructed for the design and analysis of knowledge co-production by integrating concepts across the co-production and urban social-ecological-technological systems literatures. In Chapter 4, the conceptual framework is used to analyze two case studies of knowledge co-production in the Miami Metropolitan Area to better inform decisions for how and when to employ co-production as a tool to achieve sustainability and resilience outcomes. In Chapter 5, six propositions are presented – derived from a synthesis of the literature and the three empirical cases – that knowledge professionals can employ to create, facilitate, and scale up knowledge system innovations: flatten knowledge hierarchies; create plural and positive visions of the future; construct knowledge co-production to achieve desired outcomes; acknowledge and anticipate the influence of power and authority; build anticipatory capacities to act under deep uncertainty; and identify and invest in knowledge innovations. While these six propositions apply to the context of coastal cities and flood resilience, most can also be useful to facilitate knowledge innovations to adapt to other complex and intractable environmental problems. Cities must move swiftly to create and catalyze knowledge system innovations given the scale of climate impacts and rapidly changing environmental conditions. / Dissertation/Thesis / Doctoral Dissertation Sustainability 2020

Skyfallen förväntas öka, därmed behöver städer klimatanpassas. Ansvarsfördelningen i hanteringen av skyfall är komplicerad då det finns otydligheter hur aktörer ska arbeta med åtgärder vid dessa översvämningar. Syftet för studien är att undersöka ansvarsfördelning, samverkan och klimatanpassningsarbete i två kommuner vid översvämningar i samband med extrema skyfall. Teorin om samarbetsstyrning innebär att fler aktörer ska samverka vid komplexa händelser för att uppnå en urban resiliens. Teorin ska som utgångspunkt analysera fallen Malmö och Gävle där även kvalitativa metoder har använts. Resultatet visar att kommunerna inte har hela ansvaret vid skyfall. Det finns även liknande synsätt på hur kommunernas ansvar bör utvecklas, samt tydlighet kring samordning. Därmed är slutsatsen att översvämningar först tas i beaktande efter att händelsen har skett, något som också driver ett ansvarstagande. Alla aktörer måste tidigare ta ett eget ansvar samt samverka för att uppnå klimatanpassade städer innan det är för sent. / Rainfall is expected to increase, and cities need to adapt. The distribution of responsibilities is complicated because of uncertainties about who and how actors should work with flood risk management. This study aims to investigate these responsibilities, collaborative workn and climate adaptation in two municipalities during floods from extreme rainfall. The theory of collaborative governance is used to study how actors collaborate to achieve urban resilience in the cases of Malmö and Gävle. The results show that municipalities are not the only ones with responsibility during heavy rainfall. There are also similar views on how the municipalities responsibilities should be developed, as well as the importance of clarity around collaborative governance. The conclusion is that floods are only taken into account after the event has occurred, something that also drives the distribution of responsibility. All involved actors must take their own responsibility and collaborate to achieve adapted cities before it is too late.

Le parc national Banff, joyau du réseau de Parcs Canada, est l’objet d’une anomalie : il contient une ville à l’intérieur même de ses frontières. Si, au moment de la création de Banff, les gestionnaires du parc jugeaient le développement urbain compatible avec ces espaces protégés, depuis les années 1980, leur priorité est passée à la protection de la nature. Bien que la Loi sur les parcs nationaux du Canada prévoit que les parcs ont une double fonction, soit l’utilisation par le public et la protection pour les générations futures, le principe de l’intégrité écologique impose un impératif juridique et moral à ce dernier aspect. Dès lors, on imposa à la ville de Banff d’importantes limites à son développement en accord avec le principe d’absence d’effets nuisibles sur l’environnement, parmi lesquelles le plafonnement de sa population à 8000 habitants, la limitation de son périmètre urbain à 3,93 km2, ainsi que sa superficie commerciale plafonnée à 10 %. Il semble ainsi que la ville et le parc national ont une relation d’interdépendance unique, évoluant en fonction de la succession des paradigmes environnementaux. En ajoutant la résilience urbaine à l’équation, nous chercherons à comprendre comment ce concept peut sous-tendre de manière durable la définition du rapport dynamique entre la ville de Banff et les écosystèmes du parc. Ce mémoire sera donc l’occasion d’étayer les multiples politiques de protection de la nature en vigueur à Banff à travers une étude de cas exploratoire, puis de l’interpréter en fonction des différentes éthiques de l’environnement et à travers la théorie de la résilience urbaine. À cet égard, les politiques de protection de la nature seront évaluées en fonction de critères de résilience urbaine identifiés dans la littérature scientifique. / Banff National Park, Parks Canada's jewel, is characterized by a peculiar anomaly: it contains a small town within its boundaries. While at the time of Banff's creation, park managers considered urban development compatible with these protected areas, since the 1980s, their priority then switched to nature protection. Although the Canada National Parks Act states that parks have a dual function of public use and protection for future generations, the principle of ecological integrity places a legal and moral imperative on the latter. As a result, the town of Banff was subject to significant limitations on its development consistent with the “no net negative environmental impact” principle, including a population cap of 8,000, a town perimeter limit of 3.93 km2, and a commercial land area limit of 10%. It thus seems that the town and the national park have a unique interdependent relationship, evolving according to the succession of environmental paradigms. By adding urban resilience to the equation, we will seek to understand how this concept can sustainably underpin the definition of the dynamic relationship between the town of Banff and the park’s ecosystems. This master’s thesis will therefore be an opportunity to identify the multiple nature protection policies enforced in Banff through an exploratory case study, then to interpret it according to the different environmental ethics and through the urban resilience theory. Nature protection policies will also be evaluated according to the urban resilience criteria found in the literature on the subject.

Over the past decades, the fast-changing global climate poses a significant challenge to many cities around the world to embrace resilience concepts, whereby a safe-to-fail planning approach replaces traditional fail-safe practices. The change in perspectives has seen an increase in climate-adapted infrastructural projects being integrated with the new urban planning agendas across the world. The investigation conducted was designed to understand the process of how resilience concepts travel between different cities, by investigating the actors who move policy knowledge, their roles in it, as well as the knowledge transfer process mechanism that is responsible for the movement of such policies. The investigation took advantage of a scoping study technique to answer the research questions, using mostly secondary data and an interview to verify the secondary sources. The findings and the discussion provided insights on who is involved in resilience policies and how these policies are transferred from one place to another. The investigation uncovered the influence policy mobilizers has on the movement of policy knowledge, as well as how the mobilization of policy knowledge can both be beneficial or detrimental, depending on the way it was moved or implemented. / Under de senaste decennierna utgör det snabba föränderliga globala klimatet en betydande utmaning för många städer runt om i världen med att anamma motståndskraftskoncept, där en planeringsstrategi med säkerhet att misslyckas ersätter traditionella felsäkra metoder. Förändringen i perspektiv har ökat klimatanpassade infrastrukturprojekten som integrerats med nya stadsplaneringsagendorna över hela världen. Studien genomfördes för att få en förståelse av hur motståndskraftskonceptet färdas mellan olika städer och detta genomfördes genom att undersöka de aktörer som förflyttar politisk kunskap och deras roller i den samt den kunskapsöverföringsmekanism som är ansvarig för rörelsen av sådan politik. Studien utnyttjade en scoping-studieteknik för att få svar på forskningsfrågorna, med mestadels sekundär data och en intervju för att verifiera sekundärkällorna. Resultaten och diskussionen gav insikter om vem som är inblandad i motståndskraft och hur policy överförs från en plats till en annan. Studien avslöjade även inflytande av politiskt mobilisering och kunskap som både kan vara fördelaktig eller skadlig beroende på hur den flyttades eller genomfördes.

[pt] Estimulado pela percepção de um crescente uso do termo “resiliência” em documentos oficiais, em ambientes acadêmicos e no vocabulário popular, o presente trabalho procura explorar as condições para a propagação do termo, assim como as consequências de seu uso em políticas públicas. O conceito, popularizado no contexto da disciplina da biologia, foi transportado para as ciências sociais a partir de uma aproximação entre as racionalidades da ecologia e da economia. Este movimento de aproximação resultou em uma nova concepção do mundo social como complexo, permeado por toda sorte de riscos, e habitado por sujeitos fundamentalmente vulneráveis. A ampla mobilização do conceito na Nova Agenda Urbana, principal documento da ONU-Habitat para a formulação de políticas urbanas, demonstra o grau de legitimidade conquistado pela ideia de resiliência urbana. Para melhor entendermos como esta ideia é invocada na prática, analisaremos seu uso nos contextos do Furacão Katrina, quando atingiu o sul dos Estados Unidos, em 2005, e no rompimento da barragem da Samarco em Mariana, ocorrido em 2015 em Minas Gerais. / [en] Encouraged by the perception of a growing use of the term resilience on official documents, in academic environments and in the popular vocabulary, the present work aims to explore the conditions for the dissemination of the term, as well as the consequences of its use in public policy discourses. The concept, which was popularized in the context of the biological sciences, was transported to the social sciences through a theoretical convergence between the rationalities of ecology and economy. This movement resulted on a new conception of the social world, in which it is conceived as complex, permeated by all sorts of risks, and populated by fundamentally vulnerable subjects. The wide employment of the concept by the New Urban Agenda, UN-Habitat s main document for urban policy formulation, demonstrates the degree of legitimacy that was conquered by the idea of an urban resilience. In order for us to better understand how the idea is evoked in practice, we will analyze its use in the contexts of Hurricane Katrina, when it hit the South of the United States, in 2005, and in the context of Samarco s dam rupture in Mariana, which took place in 2015, in Minas Gerais.

La succession de plus en plus fréquente d’événements catastrophiques a amené les sociétés à poser les conditions d’une gestion proactive des risques « naturels ». Ainsi, dans une perspective exploratoire, nous étudions les processus de planification du rétablissement postcatastrophe et la place qu’occupe le concept de résilience urbaine au sein des pratiques de cette planification et des contenus et produits qui en sont issus. Nous entamons plus spécifiquement une réflexion entourant l’intelligibilité et l’opérationnalisation de la résilience. Pour ce faire, nous examinons deux cas signifiants d’inondation dans l’historique nord-américain, soit celui de la Nouvelle-Orléans en Louisiane et celui de la ville québécoise de La Baie, ayant été respectivement victimes des ouragans Katrina et Rita en 2005 et des pluies diluviennes de 1996. Après avoir procédé à une brève mise en contexte des désastres éprouvés, de leurs effets et des vulnérabilités physico-spatiales qu’ils ont mis en exergue, nous mettons en parallèle les logiques institutionnelles précatastrophe d’aménagement du territoire, d’urbanisme et de gestion des risques des villes. Nous observons ensuite l’évolution des deux processus de planification du rétablissement et les enjeux et débats qui les ont caractérisés, pour terminer avec une exposition des changements résilients qui en ont émané. Les deux derniers chapitres démontrent que la qualité de résilience des villes est fortement influencée par leurs cultures politiques, administratives et législatives propres et leurs traditions urbanistiques. Bien qu’elles aient su élaborer une stratégie de prévention des risques, qui accepte les inondations plutôt que de tenter de s’y opposer à tout prix, elles n’ont toutefois pas saisi l’entièreté des opportunités qui s’offraient à elles. / A higher rate of catastrophic events has brought societies to set out the conditions of proactive “natural” risk management. As a result, and from an exploratory perspective, we are studying post-disaster recovery planning processes and the importance of the concept of urban resilience in these planning practices as well as the contents and products which stem from it. More specifically, we begin reflecting upon the intelligibility and operationalization of resilience. To do so, we will focus on two significant cases of flooding in North America: New Orleans, Louisiana, and the city of La Baie, Quebec, which were respectively victims of hurricanes Katrina and Rita in 2005 and of torrential rain in 1996. After a brief contextualization of these disasters, of their effects and of the physico-spatial vulnerabilities that they highlighted, we will link pre-disaster institutional logic regarding territorial planning, urban planning, and city risk management. Next, we observe the evolution of these two recovery planning processes as well as their characteristic issues and debates, finishing with a overview of subsequent resiliency changes. The last two chapters demonstrate that the quality of resilience of cities is strongly influenced by political, administrative and legislative culture as well as urban traditions. While they were able to design risk prevention strategies which accept flooding rather than trying to oppose it at all costs, they did not fully grasp all the opportunities that were offered to them.
