Abstract Many capital cities are expanding bicycle lanes or investing in public bike-sharing systems to make cycling mobility a viable transport solution within urban areas. While bicycles are fit for short-distance trips (<15 minutes), their attractiveness declines for longer trips (Ton et al., 2020; Handy et al., 2014; Jäppinen et al., 2013). So, it is opportune to estimate to what extent the accessibility can be increased when intermodal solutions are available. In this paper, a quantitative analysis of different mobility scenarios is conducted. The aim is to evaluate how time travel and accessibility to amenities by bike, can be improved if public transportation such, as the train, is considered. The analysis uses open data and detailed GIS-based network analysis to examine the spatial relationship between transport opportunities, travel time and amenities access in Lisbon, Portugal. Three mobility scenarios are considered: in the first scenario, short-distance trips by bike from home are evaluated (15- minute travel). Then, to evaluate the contribution in time travel of potential modal shift (bike and train) vs individual car, second and third scenarios are presented considering longer distance travels within the city of Lisbon, during peak hours. Results suggest that for longer trips, the combined use of bicycle and train infrastructure can be a faster or more convenient alternative to individual car use. Also, multimodal cycling can expand riders’ area of influence and thus increase the accessibility to opportunities. So, people living near train stations can beneficiate from a “potential” proximity to a diversity of amenities that are geographically more distant. In Lisbon, 34% of the population live within the 10-minute bicycle catchment areas around the 8 train stations from Cintura Line and can thus benefit from this combination of transport modes. City planners can use this methodology to prioritize spaces where investing in accessibility can have the largest impact in terms of improving connections between homes and destinations. This methodology, developed and tested in Lisbon, can be applied in other cities to support planning interventions regarding sustainable transport alternatives.

O presente artigo resume o processo de evolução histórica da política urbana no Brasil e em Portugal, a partir dos principais aspectos do seu contexto político e respectivos marcos regulatórios. Pela análise empreendida foi possível constatar que ambos os países sofreram com o acelerado processo de urbanização ocorrido na segunda metade do século XX, com as transições e alternâncias entre os regimes conservadores e democráticos, mas possuem uma legislação urbanística nacional avançada e que prima pela eficácia na implementação de seus instrumentos urbanísticos. O desafio está na sua implementação e articulação com as demais políticas setoriais que, em sua maioria, seguem de forma independente e limitadas na sua vertente territorial, bem como no fomento de uma cultura coletiva político-administrativa territorial, envolvendo técnicos, gestores, comunidade profissional e cidadãos em geral para que conheçam e apliquem de forma adequada os instrumentos regulados.

This article summarizes the process of historical evolution of urban policy in Brazil and Portugal, based on the main aspects of its political context and its regulatory frameworks. The analysis shows that both countries have suffered from an accelerated process of urbanization in the second half of the twentieth century, with transitions and alternancesbetween conservative and democratic regimes. However, they have advanced national urbanistic legislations, effective in implementing their urbanistic instruments. The challenge lies in their implementation and articulation with other sectoral policies, which, in most cases, remain independent and limited in terms of territory, as well as fostering a collective territorial political-administrative culture, involving technicians, managers, the professional community and citizens in general so that they know and apply the regulated instruments in an appropriate manner.

Abstract: This article proposes the modelling and implementation of an integrated system for Brazilian cadastres, based on the standardized model of land administration described in the ISO 19152:2012 LADM. The model was developed from the identification of the essential elements of the urban, the National Rural Cadastre System and the cadastres of public assets of the Secretariat of the Patrimony of the Union. At all stages of this work, free and/or open source software was used to validate this proposal. The results confirm the viability of the application of the concepts proposed by LADM to the Brazilian system of cadastres, allowing the integration between the systems of different institutions. The model is flexible and allows for the inclusion of additional classes according to changing needs of land administration data users. The current form of the model can be regarded as the basic module to be used as a starting point in the structuring of the National System of Management of Territorial Information, which is aimed at the integration of all existing cadastres and land registries in Brazil.

Abstract Reducing ‘Greenhouse Gas’ emissions, particularly of CO2, is a global commitment which has gained predominance with the emergence of sources that generate renewable energy as an alternative to traditional energy produced through fossil fuels. Renewable or ‘soft’ forms of energy are all those which use the elements of nature - for example, the wind and the sun - to generate energy without damaging the environment. ‘Geographic Modelling’ is an essential tool to better determine regions that have economically feasible energy potential, based on natural alternative sources. Therefore, the objective of this study was to identify energy potential based on wind and solar renewable sources. To achieve such goal, conceptual models of spatial analysis were designed and developed, in accordance with the norms established by the 'Object Modelling Technique' and by the operational models provided by 'ModelBuilder'. A test was applied in the south-central region of 'Continental Portugal'. The results showed average potential to generate wind energy and high potential to produce solar energy in the region.
