Contributions towards smart cities : exploring block level census data for the characterization of change in Lisbon

The interest in using information to improve the quality of living in large urban areas and its governance efficiency has been around for decades. Nevertheless, the improvements in Information and Communications Technology has sparked a new dynamic in academic research, usually under the umbrella term of Smart Cities. This concept of Smart City can probably be translated, in a simplified version, into cities that are lived, managed and developed in an information-saturated environment. While it makes perfect sense and we can easily foresee the benefits of such a concept, presently there are still several significant challenges that need to be tackled before we can materialize this vision. In this work we aim at providing a small contribution in this direction, which maximizes the relevancy of the available information resources. One of the most detailed and geographically relevant information resource available, for the study of cities, is the census, more specifically the data available at block level (Subsecção Estatística). In this work, we use Self-Organizing Maps (SOM) and the variant Geo-SOM to explore the block level data from the Portuguese census of Lisbon city, for the years of 2001 and 2011. We focus on gauging change, proposing ways that allow the comparison of the two time periods, which have two different underlying geographical bases. We proceed with the analysis of the data using different SOM variants, aiming at producing a two-fold portrait: one, of the evolution of Lisbon during the first decade of the XXI century, another, of how the census dataset and SOM’s can be used to produce an informational framework for the study of cities.

How to improve urban mobility in Lisbon: intermodality and information and ticketing systems

Urban mobility is one of the main challenges facing urban areas due to the growing population and to traffic congestion, resulting in environmental pressures. The pathway to urban sustainable mobility involves strengthening of intermodal mobility. The integrated use of different transport modes is getting more and more important and intermodality has been mentioned as a way for public transport compete with private cars. The aim of the current dissertation is to define a set of strategies to improve urban mobility in Lisbon and by consequence reduce the environmental impacts of transports. In order to do that several intermodal practices over Europe were analysed and the transport systems of Brussels and Lisbon were studied and compared, giving special attention to intermodal systems. In the case study was gathered data from both cities in the field, by using and observing the different transport modes, and two surveys were done to the cities users. As concluded by the study, Brussels and Lisbon present significant differences. In Brussels the measures to promote intermodality are evident, while in Lisbon a lot still needs to be done. It also made clear the necessity for improvements in Lisbon’s public transports to a more intermodal passenger transport system, through integration of different transport modes and better information and ticketing system. Some of the points requiring developments are: interchanges’ waiting areas; integration of bicycle in public transport; information about correspondences with other transport modes; real-time information to passengers pre-trip and on-trip, especially in buses and trams. After the identification of the best practices in Brussels and the weaknesses in Lisbon the possibility of applying some of the practices in Brussels to Lisbon was evaluated. Brussels demonstrated to be a good example of intermodality and for that reason some of the recommendations to improve intermodal mobility in Lisbon can follow the practices in place in Brussels.

Lisbon Saravasti: A Experiência da Viagem pelas Heranças de Lisboa

Do que falamos quando verbalizamos a experiencia do espaço e do tempo. Falamos do que somos ou falamos do que vemos. A experência do ser no espaço e no tempo delimita um objeto fenomenológico que se contem a sim mesmo. A poética da intersubjectividade é uma proposta da epistemologia crítica para resolução da velha questão do contexto e da circunstância . Nós somos o que somos pela expereiencia no mundo, ao mesmo tempo que o que fazemos e como o fazemos molda o que somos. Propomos uma epistemologia em que o sugeito participa na construção dos seu objeto. Uma formula em que o uno se concretiza no todo. Neste livro, que tem por cenário da Baixa de Lisboa, trabalhamos algumas questões conceituais relacionadas com a poética da intersubjectividade . Num primeiro momento trabalhamos a poética do tempo. O tempo como fenómeno social inscrito na mudança como construtor de vínculos entre as comunidades. Olhamos para as suas memórias, para as suas técnicas, para os seus rituais e para as diferentes narrativas que permitem criar escalas de observação da intensividade e da extensividade dos fenómenos. Escalas que são observadas nas continuidades e nas rupturas desses fenómenos, visíveis através das memórias e dos esquecimentos. As narrativas de legitimação. De seguida procuraremos na poética do espaço a relação entre as escalas de observação e os processos de polarização no espaço. As diferentes escalas do espaço permitem olhar para a sua estruturação como narrativa de legitimação cristalizadas nas dinâmicas de fluxos. De seguida trabalhamos a poética da viagem, uma metodologia que permite ao observador deslocar-se entre as escalas de observação, olhar para as qualidades do espaço e do tempo, para as sua quantidades e para o modos como os indivíduos se apropriam e se organizam criando estabilidades ou instabilidades reagindo a causas internas ou externa. Na poética da viagem construímos a nossa narrativa simbólica, procurando a forma, os valores e os ritmos da Baixa a duas mãos.

The post-Lisbon role of the European Parliament in the EU's Common Commercial Policy: Implications for bilateral trade negotiations. EU Diplomacy Paper 05/2012, July 2012

This paper sets out to conduct an empirical analysis of the post-Lisbon role of the European Parliament (EP) in the EU’s Common Commercial Policy through an examination of the ‘deep and comprehensive’ bilateral Free Trade Agreements (FTAs) currently negotiated as part of the EU’s Global Europe strategy. The EU-Korea and EU-India FTAs are used as case studies in order to determine the implications of the EP’s enhanced trade powers on the processes, actors and outcomes of EU bilateral trade policy. The EP is now endowed with the ‘hard power’ of consent in the ratification phase of FTAs, acting as a threat to strengthen its ‘soft power’ to influence negotiations. The EP is developing strategies to influence the mandate and now plays an important role in the implementation of FTAs. The entry of this new player on the Brussels trade policy field has brought about a shift in the institutional balance of power and opened up the EP as a new point of access for trade policy lobbyists. Finally, increased EP involvement in EU trade policy has brought about a politicisation of EU trade policy and greater normative outcomes of FTAs.

Transport of the smoke plume from Chiado’s fire in Lisbon (Portugal) sensed by atmospheric electric field measurements

The Chiado’s fire that affected the city centre of Lisbon (Portugal) occurred on 25th August 1988 and had a significant human and environmental impact. This fire was considered the most significant hazard to have occurred in Lisbon city centre after the major earthquake of 1755. A clear signature of this fire is found in the atmospheric electric field data recorded at Portela meteorological station about 8 km NE from the site where the fire started at Chiado. Measurements were made using a Benndorf electrograph with a probe at 1 m height. The atmospheric electric field reached 510 V/m when the wind direction was coming from SW to NE, favourable to the transport of the smoke plume from Chiado to Portela. Such observations agree with predictions using Hysplit air mass trajectory modelling and have been used to estimate the smoke concentration to be ~0.4 mg/m3. It is demonstrated that atmospheric electric field measurements were therefore extremely sensitive to Chiado’s fire. This result is of particular current interest in using networks of atmospheric electric field sensors to complement existing optical and meteorological observations for fire monitoring.
