Abstract(s)
Cada vez com maior frequência se ouve relatar a ocorrência de fenómenos perigosos
que provocam impactos sociais e económicos. Em parte, tal facto deve-se ao acréscimo
da frequência e da intensidade de alguns fenómenos naturais extremos, nomeadamente
cheias rápidas, secas e incêndios florestais. Conjugado com esta realidade, o aumento da
exposição das populações a estes fenómenos, revela a importância do ordenamento do
território na gestão da interação homem/espaço natural através da organização espacial
das atividades humanas.
Apresenta-se uma metodologia que, em função dos riscos e das suscetibilidades
presentes numa área geográfica, permite identificar a melhor localização para a
ocupação humana do território tendo em vista a segurança de pessoas, bens e ambiente.
Após a aplicação da metodologia aos concelhos de Arruda e Vila Franca de Xira,
verifica-se a existência de 1.722 e de 34.407 edifícios localizados em áreas com
restrições na ocupação do solo. Por outro lado, a superfície sujeita a interdições ou
condicionalismos nestes concelhos representa cerca de 47% e 93% respetivamente.
Apresentam-se mapas finais com os resultados da metodologia aplicada aos dois
concelhos, segundo a distribuição das diferentes classes de ocupação sugeridas, que
podem ser utilizados na definição das opções.
It is increasingly common to hear reporting the occurrence of dangerous phenomena that causes social and economic impacts. This is partly due to the increased frequency and intensity of some extreme natural phenomena, namely sudden floods, droughts e forest fires. Along with this reality, the increased exposure of the populations to these phenomena indicates the importance of land planning in the management of man/natural area interaction through the spatial organization of human activities. It is now presented a methodology that, according to the risks and susceptibilities (present) in a given geographical area, enables to identify the best location for the human occupation of the territory, bearing in mind the safety of persons, goods and environment. Further to the application of this methodology to the municipalities of Arruda dos Vinhos and Vila Franca de Xira, it has been identified that 1,722 and 34,407 buildings are located in areas with restrictions on land occupation. On the other hand, the surface subject to interdictions or restrictions in these municipalities represents about 47% and 93% respectively. Final maps are presented with the results of the methodology applied to these two municipalities, according to the distribution of the suggested different classes of occupation, and which can be used in the definition of the options.
