Reprocessamento e reutilização de material odonto-médico-hospitalar de uso único: busca de evidências pela revisão sistemática de literatura científica / Single-use medical devices reprocessing and reuse: search of evidences through systematic reviews of scientific literature.

Denser, Carla Patricia Amaral Carvalho 24 August 2004 (has links)
Este estudo é baseado no fato inegável de que a prática do reprocessamento e reutilização de artigos odonto-médico-hospitalares é ampla no país e no mundo, apesar de não existir consenso científico para tal, principalmente pela enorme variedade de materiais e de artigos disponíveis no mercado. Neste trabalho foi aplicada metodologia de revisão sistemática de literatura científica, cuja investigação partiu de uma questão específica e utilizou fontes abrangentes com estratégias de busca explícitas, baseada em critérios aplicados uniformemente, com avaliação reprodutível. O objetivo foi selecionar publicações sobre o reprocessamento e reuso de artigos odonto-médico hospitalares de uso único de acordo com uma questão de pesquisa específica, revisar a qualidade metodológica destes estudos e discutir evidências para aplicação prática e de pesquisa deste conhecimento. A questão de pesquisa foi: Qual a efetividade e a segurança da prática de reprocessamento e reutilização de materiais odonto-médico hospitalares de uso único? Os dados foram coletados de estudos selecionados, sendo 20 estudos básicos e 01 de revisão não sistemática. Para análise e avaliação dos estudos básicos selecionados utilizou-se, como sistematização, a seguinte categorização inicial: escopo; tipo de pesquisa; sujeitos ou objetos da pesquisa; população; procedimentos da pesquisa; análise dos dados; resultados; conclusão; comentários da analisadora. Devido à epecificidade dos conteúdos obtidos das pesquisas analisadas sob esta categorização, foram acrescentadas novas categorias, com a finalidade de refinar, agregar e correlacionar as informações obtidas, em quadros e tabelas, com a seguinte configuração final: tipos de artigos investigados; escopos; tipos de investigação; tipos de análises realizadas; resultados; conclusões. Os resultados mostraram que grande parte dos artigos é composta de plásticos, possui lumens e tem conformação complexa, significando que são artigos de difícil limpeza e descontaminação, cujos resultados podem, sob circunstâncias comparativas controladas, ser também considerados para artigos menos complexos e com menor dificuldade para seu reprocessamento. A finalidade foi obter informações que suportem ou não a prática de reprocessamento e reutilização de artigos odonto-médico-hospitalares de uso único. A conclusão é de que, com base no conhecimento atual, não é possível propor o reprocessamento e reuso de todos os artigos de uso único indiscriminamente, mas é possível selecioná-los para testar e validar protocolos de reprocessamento e reuso de artigos odonto-médico-hospitalares baseados em conhecimentos científicos com graus de evidência bem estabelecidos, utilizando este conhecimento para a construção de políticas nacionais de saúde menos restritivas de recursos altamente tecnológicos para a Saúde Pública. / This study is based on the undeniable fact that single-use medical devices reprocessing and reuse is a large practice in the country and also the world, although there is no scientific consensus for such, mainly due to the enormous variety of materials and available articles in the market. In this study, methodology of systematic review of scientific literature was applied. The inquiry started up as a specific question and used wide sources with explicit strategies of search, based in criteria applied uniformly. The objective was to select publications in accordance to the single-use medical devices reprocessing and reuse using a specific question research, to revise the methodological quality of these studies and to discuss evidences for practical application and also for research of this knowledge. The research question was: Are the single-use medical devices reprocessing and reuse a safe and effective practice? The data was collected from selected studies, being 20 basic studies and 01 narrative review. For analysis and evaluation of the basic studies as systematization, the following initial categories are used: target; type of research; research\'s objects; population; research\'s procedures ; data analysis; results; conclusion; author\'s analysis. The results have shown that a great part of articles is composed of plastics, possesses lumens and has complex conformation, meaning that they are articles of difficult cleanliness and decontamination, which results can, under controlled comparative circumstances, also be considered for less complex articles and with lesser difficulty for reprocessment. The aim was to get information that supports or not SUDS reuse. The conclusion is that, according to the current knowledge, it is not possible to consider reprocess and reuse of all single-use devices indiscriminately. It is possible to select them for testing and to validate reprocess and reuse guidelines based in scientific evidences and using this knowledge for the construction of less restrictive National Health Policies for the Public.

Estudio, análisis y diseño de secciones permeables de firmes para vías urbanas con un comportamiento adecuado frente a la colmatación y con la capacidad portante necesaria para soportar tráficos ligeros

Rodríguez Hernández, Jorge 11 July 2008 (has links)
Los firmes permeables forman parte de la tendencia de construcción sosteniblecomo uno de los Sistemas Urbanos de Drenaje Sostenible (SUDS) más completos. Paraestudiar la capacidad de infiltración en laboratorio, se ha desarrollado el ensayo deresistencia a la colmatación con el Infiltrómetro Cántabro Fijo (ICF). Este ensayo es unaherramienta eficaz para la caracterización de diferentes tipos de pavimentos permeables,exponiéndolos a un aporte conocido de agua, variando el estado de colmatación y lainclinación de la superficie. Además, para estudiar la capacidad de infiltración encampo, se ha desarrollado el Infiltrómetro Cántabro Portátil (ICP), el cual permiteidentificar claramente cualquier tipo de superficie, permeable o impermeable, así comosu capacidad de infiltración. Respecto a la degradación de los materiales, se haanalizado la afección de los vertidos de hidrocarburos sobre mezclas bituminosasporosas fabricadas con distintos tipos de betunes. Por último, se han construido modelosde firmes permeables en el Laboratorio (FIDICA), en el Campus de Santander de laUniversidad de Cantabria y en el aparcamiento experimental de la Guía en Gijón. / Pervious pavements are part of the trend of sustainable construction as one of themost complete Sustainable Urban Drainage Systems (SUDS). The clogging resistancetest with the Fixed Cantabrian Infiltrometer (FCI) has been developed to study theinfiltration capacity in laboratory. The FCI is an effective tool for the characterization ofdifferent pervious pavements types, exposed to a known contribution of water, varyingclogging conditions and slope. Besides, the Portable Cantabrian Infiltrometer (PCI) hasbeen developed to study the infiltration capacity in field. The PCI allows clearlyidentifying any type of surface, pervious or impervious, as well as its clogging level.Regarding the materials degradation, the affection of hydrocarbons leakages overporous asphalt has been analysed. Lastly, models of pervious pavements have been builtin the FIDICA Laboratory and in the Santander Campus of the University of Cantabria,besides several experimental parking bays in La Guía, Gijón.

Integrating the planning of green spaces and sustainable drainage systems

Singh, Rohit January 2012 (has links)
In recent times urban flooding has become more frequent and more complex due to the effects of increasing urban areas and climate change. In some established urban areas the existing drainage infrastructure is unable to cope with the volume of surface runoff and flooding events are more frequent, therefore new approaches to create more space for water within developments are required. This research was conceived in that context. It aims to investigate the potential for integrating green space planning with water planning and to develop a framework for the same in order to reduce the risk of flooding. An extensive literature review was carried out in the areas of urban planning, water planning, planning legislations, and issues related to integrating green space and water planning. The review identified the need for an inclusive framework which could integrate aspects of green space and storm water planning more holistically to achieve greater spatial planning efficiency. To satisfy this need, a conceptual framework was developed which took into consideration the opinions of various stakeholders. The conceptual framework included green spaced planning for SUDS, recreational and storm water indicators and a mechanism for integrated evaluation of SUDS for recreation and storm water management. The conceptual framework provided a joint approach where both engineers and planners will need to work together for the development of integrated storm water and green space plans. The framework showed processes for both disciplines and also indicates how spatial planning and water planning interfaced so that there was clarity of roles. In order to evaluate integrated plans, an ‘integrated evaluation tool’ was developed which uses indicators from both the areas of green space planning and water planning. The evaluation tool also contained a scoring system which can be used to select storm water management options with more recreational potential. The tool provides a mechanism to balance the requirements of recreation and storm water management so that more holistic solutions can be developed by teams of engineers and planners. The conceptual framework and the integrated evaluation tool were applied to two case study catchments. Results from the case studies showed the relationship of spatial planning and flooding. It further tested whether recreational aspects could be integrated into storm water planning. A number of drainage options were tested to show the application of the evaluation tool under various scenarios. This results of the research showed that the conceptual framework was appropriate in both case study areas even though the areas had different patterns of development. It is therefore proposed that the approach has potential for wider application in other geographical areas. Results from the two areas also showed that the integrated approach established in this research could enhance the recreational aspects associated with urban storm water management. The framework presented in this thesis will potentially be of use to a wide range of stakeholders such policy makers, local authorities, water companies, consultants and researchers. It could also be useful in informing the evolution of planning policies and technical guidance associated with water and green space planning.

Accumulation, transport and potential treatment of surface sediment on car parks with channel drains

Barlow, James Vincent January 2015 (has links)
Urban pollutants have been identified as a significant source of environmental pollution, posing a risk to human health, the environment, and are toxic to flora and fauna. Highways are recognised as one of the key sources of pollution, from both vehicles, and surrounding infrastructure. A number of studies have investigated accumulation of sediment and the associated pollutants on highways, and the runoff generated as a result of rainfall. Car parks share many potential contributory sources of pollutants with highways, but there is a lack of studies regarding car parks, despite them being identified as a significant percentage of urban land use. A series of experiments were undertaken in order to develop an understanding of the characteristics of car park sediment. The physical and chemical characteristics of sediment were analysed at different stages throughout the drainage system. Firstly on the sediment accumulated on car park surfaces, followed by that mobilised and transported into a channel drain during simulated rainfall events. Finally, potential treatment of pollutants within sediment in a channel was quantified. The physical and chemical characteristics of car park sediment was shown to be similar during both the accumulation (build-up) and wash-off stages, suggesting that the accumulated sediment is generally mobilised and transported to the channel drain (wash-off). Furthermore, both the physical and chemical characteristics of the sediment were shown to be similar to those found on highways, thorough the build-up and wash-off phases. Finally, potential treatment of organic pollutants (PAH) by biodegradation was demonstrated, but not comprehensively proved.

Implementering av öppna dagvattenanläggningar i innerstaden: En studie för att undersöka lämpligheten med öppna dagvattenlösningar i det befintliga stadsrummet

Johansson, Edd, Stenberg, Sofia January 2014 (has links)
Morgondagens samhällen står inför stora utmaningar såsom att hantera den ökande mängden intensiva och extrema nederbördstillfällen som förväntas att komma i framtiden. Lösningen finns i att planera och tänka på helheten om hur städerna på bästa sätt kan utformas med hjälp av funktionella öppna dagvattenlösningar för att ge en bra och effekt avrinning. Det gäller också att skapas förståelse att öppna dagvattensystem bidrar med positiva effekter till samhället, t.ex. genom att bli en resurs för stadens vegetation och grönområden och därav åstadkomma grönare och vackrare städer (Hållbar dag- och dränvattenhantering, 2011)och som gynnar folks hälsa(Viklander & Blecken 2012).Det urbana kretsloppet, skriver Butler & Davies (2011), ersätter en del av det naturliga kretsloppet och Lidström (2012) förklarar att det urbana kretsloppet lånar vatten från det naturliga och skapar då en extra loop för vattnets väg genom cirkel. Butler & Davies (2011) förklarar hur viktigt det är att det finns en förståelse kring konsekvenserna som uppstår när en del av det naturliga hydrologiska kretsloppet ersätts med en artificiell del för den urbana miljön. Lidström (2012) skriver att i naturen när det regnar och vattnet faller på en naturlig yta återvänder del av regnvattnet genom evapotranspiration och så vidare. Däremot i den urbana miljön som till viss del har en likande process fast med skillnaden att regn som fallit på en hårdgjord yta i regel blir förorenat genom att olika ytliggande, lyftburna ämnen och partiklar fastnar på vattendroppen. En av de större skillnaderna mellan det urbana och naturliga hyrdrologiska kretsloppet är reningsgraden. I det urbana hyrdrologiska kretsloppet är reningsprocessen i en mer koncentradform: reningsverken. Och i den naturliga hyrdrologiska kretsloppet är naturen i sig själv som renar vattnet. Genom att förmedla kunskap till människor och låta medborgare ha möjlighet att påverka hur införandet av Rain gardens sker kommer mycket av den misstänksamhet och skepsis som tidigare fanns att övergå i positiva åsikter. Mycket tack vare de flertalet mervärden som staden gagnar. De värden som uppstår kommer gynna den sociala aspekten i staden och bidra med ökade samhällsvinter. Bland annat genom att folkhälsan på sikt kan öka, rening av dagvattnet samt fördröjning som uppstår hjälper till att minska belastningen på reningsverken. På så sätt minskar risken för översvämningar i framtiden. / Tomorrow's communities are facing major challenges such as managing the increasing amount of intense and extreme rain water occasions that are expected to increase due to climate changes. The solution is to plan and think about the whole of how cities can best be designed, using functional open storm water solutions to give a good effect and runoff. It is also important to create an understanding that the open storm water systems contribute positive effects to society, such as by becoming a resource for the city's vegetation and green spaces, and hence achieve greener and more beautiful cities (Hållbar dag- och dränvattenhantering, 2011) and that increases people's health (Viklander & Blecken 2012).The urban cycle, writes Butler & Davies (2011), replaces part of the natural cycle and Lidström (2012) explains that the urban cycle borrows water from the natural and then creates an extra loop of water through the circle. Butler & Davies (2011) explains how important it is that there is an understanding of the consequences that occur when a part of the natural hydrologic cycle is replaced with an artificial part of the urban environment.Lidström (2012), writes that in nature, when it rains and the water falls on a natural surface returning part of the rain water through evapotranspiration, and so on. In contrast, in the urban environment that to some extent has a similar process but with the difference that the rain falling on a hard surface usually becomes contaminated by various substances and particles stick to the water droplet. One of the major differences between the urban and natural hydrological cycle is the degree of purification. In the urban hydrological cycle is the purification process in a more concentrated form: treatment plants. And in the natural hydrological cycle is nature itself that purify the water.By imparting knowledge to the citizens and letting them have an opportunity to influence the implementation of Rain gardens in their communities. Thereby might much of the suspicion and skepticism that previously existed might change into constructive opinions towards the plant, much thanks to the added value that the city benefits from the plant. The values received from the plant will benefit the social aspect of the city and contribute to increasing social benefits, including increased public health, sustainable treatment of storm water that helps to reduce the load on treatment plants. This will reduces the risk of flooding in the future.

Rainwater harvesting for drought mitigation and flood management

Melville-Shreeve, Peter January 2017 (has links)
Rainwater harvesting (RWH) in the UK has seen a low level of uptake relative to similar settings such as Australia and Germany. The relatively low cost of municipal water in the UK limits the financial savings associated with RWH systems, especially in a domestic setting. Although financial benefits can be relatively low (in terms of reduced water bills), academic and practitioner studies have demonstrated the potential for RWH to significantly reduce potable water demands at typical UK houses. Hence, increased uptake of RWH has potential to contribute to mitigating droughts in water scarce regions. Stormwater management in the UK is receiving increasing attention at all levels; from grass-roots sustainable drainage systems (SuDS) such as downpipe disconnections and raingardens; through to implementation of urban realm attenuation schemes and continued development of guidance from UK policy makers. The public realm nature of most SuDS presents a need for partnership approaches to be fostered between infrastructure mangers and the general public. The application of RWH as a technology within the SuDS management train has been limited in the UK as policy makers have taken the view that RWH tanks may be full at the start of a design storm, and thus the potential for attenuation and peak discharge reduction has been largely ignored. However, in the last few years there has been a shift in emphasis; from RWH perceived purely as a water demand management technology to a focus on its wider benefits e.g. mitigating surface water flooding through improved stormwater management. RWH systems examined in this thesis are now available which offer multiple benefits to both end-users and water service providers. The application of RWH in a dual purpose configuration (to displace potable water demands and control stormwater discharges) has seen increasing interest during the development of this thesis. However, the successful design of RWH as a stormwater management tool requires a series of calculations to be completed. To date, practitioners have frequently relied upon low-resolution heuristic methods which lead to a small range of configurations being deployed, with minimal demonstrable stormwater control benefits. In this thesis, full details of novel and traditional RWH technologies were identified and described. Empirical data was collected, both in laboratory conditions and at field sites, to identify the real world operating characteristics of a range of RWH configurations. Additionally a new time series evaluation methodology was developed to enable RWH systems to be designed and analysed. This method quantifies water demand benefits and also focusses on stormwater management metrics (i.e. largest annual discharge and total discharge volume per year). The method was developed to enable a range of RWH configurations to be evaluated at a given site. In addition, a decision support tool (RainWET) was developed and tested which enabled the methods to be deployed in real world settings. The application of the RainWET software allowed a UK-wide, time series analysis of RWH configurations to be completed and the holistic benefits of a range of dual purpose RWH systems to be analysed and described. Evidence from the UK study suggests that a traditional RWH installation (3000l storage, 300l/day demand and 60m2 roof) installed at a house in a water scarce region (London, SAAR 597mm) was able to fully mitigate stormwater overflows over a 20 year analysis whilst providing a mean water saving of 31,255l/annum. An equivalent system located in the wettest region studied (Truro, SAAR 1099mm) saw mean reductions in the largest annual storm of 62% (range 35-86%) whilst satisfying a mean rainwater demand of 50,912l/annum. The study concluded that suitably designed dual purpose RWH systems offered better stormwater management benefits than those designed without a stormwater control device. In addition, the integration of smart RWH controls were shown to maximise stormwater control benefits with little or no reduction in a system’s ability to satisfy non-potable water demands.

Fernández Barrera, Andrés H. 18 February 2010 (has links)
Esta tesis doctoral presenta la investigación del desarrollo de un prototipo de laboratorio de un sistema de captación, pretratamiento y tratamiento (SCPT) de la escorrentía proveniente de aparcamientos con firmes impermeables. El prototipo de SCPT fue estudiado en condiciones de funcionamiento inicial y a largo plazo. Las respuestas analizadas son las concentraciones de aceites y sólidos en el efluente y las eficiencias de depuración de dichos contaminantes. Finalmente, se analizó la capacidad del sistema de filtrado del SCPT para albergar colonias de microorganismos depuradores de hidrocarburos. Los niveles de depuración alcanzados por el prototipo de SCPT son superiores al 80% para el caso de los sólidos y al 90 % para los aceites, tanto en condiciones de inicio de operación, como a largo plazo tras catorce eventos de lluvia consecutivos. Además, se demostró que el sistema de filtrado es capaz de albergar colonias de microorganismos degradadores de hidrocarburo

The social dimension of stormwater management practices, including sustainable urban drainage systems and river management options

Apostolaki, Stella January 2007 (has links)
The research programme was relevant to urban planning and in particular to the design of stormwater management schemes that are more environmentally and socially acceptable. It examined social and perception issues relating to stormwater management techniques within residential areas, and in particular to the application of SUDS, mainly ponds, and river management schemes. The thesis arose from a project funded by the Environment Agency of England and Wales through SNIFFER under a programme titled “Social impacts o f stormwater management techniques including river management and SUDS”, SNIFFER Code: SUDS01. The public perception of construction is becoming a matter of increasing importance both in the UK and internationally since socio-economic parameters and public consultation both have to be taken into consideration in the planning and implementation of relevant projects. This research programme endeavoured to match the relevant legislative goals with society’s actual needs. The main aims of the research programme were to obtain an in-depth understanding and knowledge of the perceptions of popular stormwater management practices (SUDS and river management), and to evaluate these techniques from a social perspective. To satisfy these aims the following objectives were set: • To assess public awareness and perceptions of SUDS (particularly retention ponds) in the UK; • To assess professional perceptions of SUDS in the UK; • To assess perceptions of different stormwater management techniques, in three European cities; • To compare perceptions of different stormwater management techniques, SUDS and river management practices; • To link the research findings with trends in perceptions of nature and water. To meet the programme’s aims and to satisfy the objectives, the perceptions of SUDS in the UK (principally ponds) were investigated over a wide range of locations. In addition, the different river management approaches used in three heavily urbanised European cities, Glasgow, London, and Athens were investigated. The results of this research programme provide a means to understand perceptions of stormwater management and to appreciate what types of schemes will be more readily accepted by the public. The research has shown that members of the public hold strong views as to what they like or dislike about SUDS and water management installations in their local area, in spite of the fact that there were demonstrably low levels of public awareness of SUDS. The amenity, recreational value and aesthetics of new schemes seem to be of major importance for public acceptability, while function, efficiency, and maintenance are primarily important in areas facing flooding problems. Other key findings include the fact that there is a general preference for sustainable urban water management and for river restoration schemes compared with more conventional, ‘hard engineering’ approaches, such as culverting of rivers. This preference was expressed both by members of the public and by professionals involved in their planning and implementation. Another important result was that although unfamiliarity can produce negativity, education can influence attitudes positively even in sensitive issues such as safety, and can be used by authorities and planners as a means of enhancing the acceptability of new schemes. Consequently, the results of the surveys can be used as arguments towards the application of informative campaigns which should be taken into account prior to scheme implementation. This information can be utilised not only for stormwater management design, but also for other environmentally friendly constructions which the public may have a low level of awareness. Recommendations are made with respect to public and professional attitudes for improving the public acceptability of new and modified stormwater management systems. Recommendations and barriers to the uptake outlined in this thesis mainly refer to the appearance of schemes rather than technical issues. They are therefore of most use as guidance for improving aesthetics and increasing public acceptability. The outcomes of this research will be of use to policy makers, water companies, local authorities, environment agencies, planners, developers, consultants active in urban development, and researchers in applying wider-accepted practices for the assessment of public perception. Some findings from this research have been presented at several stakeholders’ meetings, at 4 conferences, and are published in the form of papers and reports, including the DTI SR 622 report titled “An Assessment of the Social Impacts of Sustainable Drainage Systems in the UK”, and the Environment Agency & SNIFFER report, SUDS01, 2005, titled “Social Impacts of stormwater management techniques including river management and SUDS”. This publication also constitutes Environment Agency R&D Technical report P2-258.

A regenerative urban stormwater management methodology. The role of SuDS construction and monitoring in the transition of a Mediterranean city

Perales Momparler, Carmen Sara 21 December 2015 (has links)
[EN] Under the well-known slogan 'think global, act local', cities in the 21st century face the enor-mous challenge of catalyzing, intensifying and accelerating sustainable urban transformations. Without losing a holistic view, the methodology presented in this thesis places the focus on 're-source management and climate mitigation and adaptation', in particular in urban stormwater management, proposing processes that can bring about the required change, shaped by the place-based approach of the regenerative sustainability paradigm. Building upon literature and practice that supports a flexible approach to stormwater manage-ment in urban environments that mimic natural processes and predevelopment hydrology (Sus-tainable Drainage Systems, SuDS) as one way to, amongst others, help to prevent and adapt to climate change, the thesis highlights the relevance of the connection to the place for adoption of best practices that conduct towards a regenerative system. Hence, it incorporates this con-nection to the place to the SuDS representation, naming it the SuDS 'landed rocket'. The proposed methodology includes a conceptual framework, specific method and tools, that allows for the understanding and the characterization of the current situation of a urban stormwater system in a process that guides future actions to move towards the desired regen-erative urban built environment concept, with a place-based holistic view. This methodology has been applied to Benaguasil, a Mediterranean city, where stormwater management is the local authority's responsibility and has been historically guided by main-stream conventional drainage practices. The thesis shows how, by taking a multi-dimensional and trans-disciplinary approach to solve environmental problems, future actions can be proper-ly addressed. Working with academia has been essential to develop wider evidence base. In this case, a sequence of research projects has advanced the innovative approach to stormwater management in Benaguasil, but it is contended that this methodology could be applied to any urban context. The thesis aims to enhance smart governance by providing information about the successful implementation and monitoring of SuDS showcase sites in Mediterranean Spain. These show-case sites are catalysts in the transition towards regenerative urban built environments in the region. In addition, it provides international examples that add further credence for improved urban ecological infrastructure by demonstrating what success can look like. / [ES] Bajo el conocido eslogan 'piensa global, actúa local', las ciudades del siglo XXI se enfrentan al gran reto de catalizar, intensificar y acelerar las transformaciones hacia un urbanismo sostenible. Desde una perspectiva holística, la metodología presentada en esta tesis se centra en 'la gestión de los recursos y la adaptación y mitigación al cambio climático', en particular en la gestión de las escorrentías urbanas, proponiendo los procesos que pueden ayudar al cambio requerido, bajo el enfoque del paradigma de la sostenibilidad regenerativa local. A partir de las referencias bibliográficas y experiencias que avalan a los Sistemas de Drenaje Sostenible (SuDS) como enfoque flexible a la gestión de las escorrentías urbanas, tratando de mimetizar los procesos hidrológicos previos al desarrollo urbano (que entre otros, contribuyen a la prevención y adaptación frente al cambio climático de las ciudades), la tesis subraya la relevancia de la conexión con el lugar para la selección de las mejores soluciones que lo conduzcan hacia un sistema regenerativo. Así, se incorpora esta conexión con el lugar a la representación de los SuDS, dándole el nombre de 'SuDS landed rocket'. La metodología propuesta incluye un marco conceptual, un método y herramientas específicas que permiten el entendimiento y caracterización de la situación actual de un sistema de drenaje urbano en un proceso que guíe acciones futuras para progresar hacia el concepto del medioambiente urbano regenerativo deseado, con una perspectiva holística local. La metodología se ha aplicado en Benaguasil, una ciudad mediterránea, donde la gestión del agua de lluvia es responsabilidad local y que ha estado influenciada históricamente por prácticas convencionales de drenaje. La tesis muestra cómo adoptando un enfoque multidimensional y multidisciplinar para resolver problemas medioambientales, las acciones futuras se pueden plantear correctamente. El trabajo con las instituciones académicas se ha demostrado esencial para desarrollar evidencias de base más amplias. En este caso, una serie de proyectos de investigación ha permitido el avance de Benaguasil hacia una gestión del agua de lluvia más innovadora. La experiencia demuestra que la metodología podría ser aplicada a cualquier otro contexto urbano. La tesis pretende mejorar la gobernanza inteligente proveyendo información respecto de la implementación y monitorización exitosas de SuDS en experiencias piloto en la España mediterránea. Estas demostraciones son catalizadoras de la transición hacia un medio ambiente urbano regenerativo en la región. Además, presenta ejemplos que se añaden al catálogo internacional de experiencias, mostrando el camino del éxito hacia un entorno urbano más saludable y habitable. / [CAT] Sota el conegut lema 'pensa global, actua local', les ciutats del segle XXI s'enfronten al gran repte de catalitzar, intensificar i accelerar les transformacions cap a un urbanisme sostenible. Des d'una perspectiva holística, la metodologia presentada en esta tesis es centra en 'la gestió dels recursos i la adaptació i mitigació al canvi climàtic', en particular en la gestió de les escorrenties urbanes, proposant processos que poden ajudar al canvi requés, des d'una òptica del paradigma de la sostenibilitat regenerativa local. A partir de les referències bibliogràfiques i experiències que avalen els Sistemes de Drenatge Sostenible (SuDS) com una aproximació flexible a la gestió de les escorrenties urbanes, tractant de mimetitzar els processos hidrològics previs al desenvolupament urbà (que entre altres, contribueixen a la prevenció i adaptació al canvi climàtic de les ciutats), la tesis subratlla la rellevància de la connexió al lloc per a la selecció de les millors solucions que el puguen conduir cap a un sistema regeneratiu. D'esta manera, s'incorpora esta connexió al lloc en la representació dels SuDS, donant-li el nom de 'SuDS landed rocket'. La metodologia proposta inclou un marc conceptual, un mètode i unes eines especifiques que permeten l'enteniment i caracterització de la situació actual d'un sistema de drenatge urbà en un procés que guie accions futures per a progressar cap al concepte de medi ambient urbà regeneratiu desitjat, amb una perspectiva holística local. La metodologia s'ha aplicat a Benaguasil, una ciutat mediterrània, on la gestió de l'aigua de pluja és responsabilitat local, i que ha estat influenciada històricament per pràctiques convencionals de drenatge. La tesis mostra com adoptant un punt de mira multidimensional i multidisciplinari per a resoldre problemes medi ambientals, les accions futures es poden plantejar correctament. El treball amb les institucions acadèmiques s'ha demostrat essencial per a crear evidències de base més amples. En este cas, una sèrie de projectes europeus d'investigació ha permès l'avanç de Benaguasil cap a una gestió de l'aigua de pluja més innovadora. L'experiència demostra que la metodologia podria ser aplicada a qualsevol altre context urbà. La tesis pretén millorar la governança intel¿ligent aportant informació respecte de la implementació i monitorització exitoses de SuDS en experiències pilot en la Espanya mediterrània. Estes demostracions son catalitzadores de la transició cap a un medi ambient urbà regeneratiu en la regió. A més a més, presenta exemples que s'afegeixen al catàleg internacional d'experiències, mostrant el camí del èxit cap a un entorn urbà més saludable i habitable. / Perales Momparler, CS. (2015).
