Abstract(s)
Cada vez mais pessoas vivem em centros urbanos, sendo a construção de infraestrutura cinzenta uma
das principais causas da destruição dos ecossistemas naturais e dos seus serviços, que são fundamentais
para o bem-estar dos cidadãos. As Infraestruturas Verdes são uma Solução Baseada na Natureza, que
tem como objetivo preservar os ecossistemas naturais através de uma rede de áreas naturais e
seminaturais, capaz de providenciar simultaneamente benefícios ambientais, sociais e económicos.
Tendo isso em conta, a Câmara Municipal de Lisboa investiu na formação de 9 corredores verdes, que
interligam vários espaços verdes.
Este trabalho teve como objetivo identificar, classificar e quantificar 10 serviços de ecossistema de
Provisão, Regulação e Manutenção, e Culturais, associados aos corredores verdes do município de
Lisboa e aos espaços verdes que os integram, tipificados com base numa classificação proposta pela
OMS. Os serviços de ecossistema, classificados de acordo com a CICES, foram quantificados com base
em indicadores, determinados a partir de dados já disponíveis ou recolhidos in-situ. Posteriormente, foi
construída uma matriz de serviços de ecossistemas que sumariza a provisão de cada serviço, em cada
corredor verde e tipo de espaço verde. Os resultados revelaram que Parques e jardins urbanos são os
espaços verdes que mais contribuem para a provisão de serviços de ecossistema nos corredores verdes,
e que os corredores Periférico e Oriental são os que mais contribuem, em geral, para a provisão de
serviços de ecossistema no município de Lisboa. Apesar de terem sido identificadas algumas
vulnerabilidades, os corredores verdes do município permitem que os residentes tenham acesso a
espaços verdes e beneficiem de serviços de ecossistema, em particular daqueles que contribuem para a
mitigação de eventos extremos relacionados com as alterações climáticas.
Currently, more and more people are living in urban centers. The construction of gray infrastructure is one of the main causes of the destruction of natural ecosystems and their services, which are essential for the well-being of citizens. Green Infrastructure is a Nature-Based Solution aimed at preserving ecosystems through a network of natural and semi-natural areas, which simultaneously provide environmental, social, and economic benefits. Taking this in consideration, Lisbon´s Municipality has invested in the development of 9 green corridors that connect several green spaces in the cities. The objective of the present work was to identify, classify, and quantify 10 ecosystem services, including Provision, Regulation and Maintenance, and Cultural services, associated with Lisbon’s green corridors and their green spaces, which were categorized based on the typology proposed by the WHO. Ecosystem services were classified according to CICES and quantified through indicators using data already available or collected in-situ. A matrix-based assessment then summarized the provision of each ecosystem service per green corridor and type of green space. The results showed that Urban parks and gardens contribute the most to the provision of ecosystem services in Lisbon’s green corridors and that the corridors Periférico and Oriental are the primary contributors to ecosystem services provision in Lisbon’s municipality. While some vulnerabilities were identified, in overall the green corridors provide residents the access to green spaces and the benefits of ecosystem services, particularly those that contribute to mitigate extreme events related to climate change.
