Urbanisation Trends and Urban Planning in the Lisbon Metropolitan Area

This article analysis the relationship between urbanisation processes and the functions and role of planning, using the case study of the Lisbon Metropolitan Area (LMA). It is based on two research projects on the LMA, one already finished and another one still in progress developed by research teams in four schools of the UTL. The information comes from two different levels of analysis: i) the study of urbanisation processes through different decades for the identification of tendencies and for an understanding of the development of the urban metropolitan condition, and ii) the study of different planning proposals and regulations for assessing the efficacy of the urban and governance regulatory system. The article is organised in four parts. The first part summarises and defines concepts for analysing urbanisation processes and trends. The second part refers to the results and the conclusions arising from the study of land use dynamics and changes taking place in the LMA through different periods. In the third part these results are evaluated in face of municipal planning proposals and land use regulations. The last part tries to draw conclusions based on convergences and divergences between urbanisation dynamics and conditions for planning control and planning practice, particularly in terms of the role of public investment policies.

The Vale de Santarém Neogene trough in the seismotectonics framework of the Lower Tagus Valley (Portugal)

The Subandean Basins of South America extending from Trinidad to Tierra del Fuego have been the object of intensive exploratory activities (Fig. 1). The largest amount of hydrocarbons discovered during the last 30 years in these basins was found in complex structural terrains. A total of 59 Billion Barrels of Oil Equivalent (BBOE) have been discovered in areas affected by compressional tectonics. Of these basins, the largest discoveries are in the Furrial Trend of Venezuela (24 BBOE), followed by the Chaco area in Bolivia and Argentina (13 BBOE), the Llanos Foothills of Colombia (4.4 BBOE), and the Madre de Dios Basin of Peru (4.2 BBOE).

Crises de fraternidade: literatura e etnicidade no Moçambique pós-colonial

Resumo: Este ensaio explora o conceito de crises de fraternidade aplicando-o ao contexto dos conflitos humanos ligados a pos-colonialidade em Mocambique, inspirando-se no conceito de fraternidade desenvolvido pelo filosofo Emmanuel Levinas. O material analisado e de natureza literaria: dois romances recentes, que desenvolvem o tema das reaccoes emocionais a Guerra Civil ocorrida na decada de 1980; e materiais memorialistas produzidos em torno a historia controversa de uma mulher branca que optou pela cidadania mocambicana no periodo posIndependencia. A nocao de “autoctonia” e explorada por relacao a diversificacao etnica no contexto pos-colonial. O artigo propoe uma complexificacao do conceito antropologico de “alteridade” e rejeita as concepcoes reducionistas da historia da nossa disciplina que tem vindo a difundir-se recentemente. Palavras-chave: autoctonia, fraternidade, Mocambique, pos-colonial.
