The Lisbon Living Lab will be centred on teenagers (young people 13 to 17 years of age) as they are a particular age group with specific needs and interests on public spaces, the relationship between teens and public spaces is very intrinsic, as public spaces may serve as a fundamental (play)ground for teenagers’ development. The Lisbon’s Alvalade neighbourhood will be living lab to explore how teenagers use and behaviour in urban fabric and what are they needs and preferences on public open spaces. The main objective is to engage teenagers in a process of the co-creation of urban spaces, by exploring the leading research question: “How can we capitalise on teenagers’ new-found love of the wired life (Thomas, 2013) to encourage them to be more outdoors?”

Rainwater harvesting systems (RWHS) can result in important benefits, but there are a number of potential negative risks. The risks associated with RWHS depend on several factors and duly consideration is required to ensure that risks associated with this type of solutions are low. Therefore, a generic and systematic approach to manage risk is required. This chapter introduces a brief overview of concepts and terminology adopted. Subsequently, an overview of common approaches to risk management is presented. The chapter focuses on specific aspects for the application of these approaches to RWHS, with emphasis on risk identification, specific risk treatment action, and monitoring. Different approaches on how to determine risks such as water safety plan (WSP), risk management process (RMP), and hazard analysis and critical control point (HACCP) can be used, but all of them have some common steps.

This chapter explores the potential of co-creation for the planning of public open spaces that could be more attentive to different, unequal and diverse social ideas, needs and desires. Co-creation is discussed as an innovative opportunity for learning and (re)thinking urban planning. Exploring ideas, literature and experiences (from the European Project C3Places), the chapter discusses the role of co-creation for involving citizens in placemaking. This reflection addresses co-creation as a collective, contextual and engaged process of learning. From this perspective, co-creation is discussed as an open process of learning about predictable ideas in the relationship between socio-spatial imaginary, requirements, needs and urban design procedures from a transformative perspective.

Public open space is a subject that belongs to us all. Every time we leave our homes, our private territory, we enter a space we have to share with others. Public space is the place for social interactions, strengthening sociability and ultimately exercising democracy. As a subject of study, public space has also long been analysed, explored and researched in various ways and under different guises, by planners, landscape architects and designers, anthropologists, social and cultural geographers, and urban historians. They all bring evidence on the role of public space in urban life, in the quality of urban environment and in the construction of cultural identity. Consequently, public space should deserve serious consideration by all - starting with those in charge and who hold regulatory responsibilities for those who use the places and ultimately give them life. As the UN-Habitat (2015) rightly recognises, a public space represents a key resource for social cohesion, economic development, and in particular liveability in urban settings. Public space is a resource that critically affects community values and positively impacts the quality of urban life. Backed by these premises, this book is about the co-creation of public open spaces, an issue at the core of the C3Places Project. To better understand the process, particularly the values of engaging people in the production of public space, is one of the C3Places’ objectives. The project is developing strategies and tools to help increase the quality and responsiveness of public spaces. In this process, the Project also aims to better understand how Information and Communication Technologies (ICTs) can influence co-creation and social cohesion. The chapters of this book bring science a little closer to the knowledge about the design, production and management of public spaces. 37 authors responded to the Project’s call to share experiences, visions and reflections on how co-creation and participatory processes can create possibilities for a sustainable and equitable future.

Face à metamorfose que se presencia na região da Avenida Almirante Reis, este capítulo discute a sua correlação com a criação de um novo discurso sobre a diversidade sociocultural. A partir do apelo a determinadas expressões — por exemplo, mundo e mundos — para enunciar a diversidade local, sugere-se a crescente transfiguração do discurso e a conexão com a economia cultural amplamente estimulada pela intervenção ali protagonizada. No desenvolvimento desta reflexão, privilegia-se o discurso produzido pela comunicação social.

Conventional treatment processes for the removal of cyanobacteria and cyanotoxins are thoroughly described in this chapter, including chemical treatment (heavy metals, herbicides, and photosensitizers), coagulation/flocculation combined with air flotation, and various adsorption processes.

Between ca.8400-7000 cal BP Late Mesolithic communities occupied the Sado valley embankments, upstream Alcácer do Sal, Portugal. The consumption of marine resources is attested by the shell waste abandoned in several sites (known as shell middens) and later confirmed by isotopic analyses on bone collagen from individuals buried in these locations. During the Mesolithic sea level was rising in response to global warming, allowing the flooding of the pre-incised Sado valley by marine water. Consequently, a question arose: did these communities colonize the margins of an estuarine environment where marine resources were available? A geophysical survey using the Electrical Resistivity Tomography (ERT) method was performed to characterize the subsurface configuration of the Sado valley and its tributaries, close to the area where shell-middens are located. Additionally, cores were collected in the proximity of the ERT profiles and sediments analysed for multi-proxies contributing to reconstruct the Mesolithic environmental conditions and landscapes. ERT models interpretation allowed recognising a deeply incised valley (~40m) in the Sado channel and less deep valleys in the tributaries. Sediment analysis suggested the presence of a brackish environment since, at least, 8400 cal BP pointing to influence of marine water near the area occupied by the Mesolithic groups.

Este artigo apresenta uma etapa de uma pesquisa mais abrangente que está em andamento na Universidade do Porto, no âmbito do grupo de pesquisa Construct-Geo, que visa avaliar os aspectos geomecânicos de materiais alternativos para uso como camada de lastro em vias férreas do tipo heavy haul. São apresentados resultados de ensaios triaxiais monotônicos e cíclicos conduzidos em corpos de prova de 150 mm de diâmetro por 300 mm de altura, em escala reduzida numa proporção de 1:2,5 em relação à granulometria de lastro padrão AREMA N. 24. Analisou-se um agregado de escória de aciaria, quimicamente e ambientalmente, inerte comparativamente a um agregado de granito, relativamente à resistência e à deformabilidade. Os ensaios cíclicos foram conduzidos em dois escalões de carga de 500.000 ciclos, sendo cada escalão compatível com o carregamento imposto por vias do tipo heavy haul com, respectivamente, 32,5 toneladas/eixo e 40 toneladas/eixo. Os resultados mostraram que o lastro de escória de aciaria apresentou parâmetros de resistência superiores comparativamente ao lastro de granito e um melhor comportamento quanto à deformabilidade, expresso por maiores valores de módulo de resiliência, menores índices de quebra e degradação de partículas e uma maior tendência de estabilização das deformações plásticas, fenômeno conhecido como shakedown e que também foi investigado.

The chapter considers the link between urban transformations in the Mouraria neighbourhood in Lisbon and the digital environment.The guiding thread of reflection is based on the tension between the production of sociocultural symbolic local references, and their (dis)appropriation by a creative economy that, relying on digital as a resource, helps to reshape the sociocultural local world into marketing. It concludes that digital has, not only a tangible social dimension, but also a tangible dimension in the processes of urban transformation. As such, it is pertinent to create alternative ways in defence of the right to the city that economize the social and its imageries taking more advantage of the articulated combination between real-digital.
