Abstract(s)
Considerando a atual conjuntura climática, é um consenso de que os espaços verdes nas grandes machas urbanas contemporâneas devem ser cada vez mais numerosos e simultaneamente mais sustentáveis, estando adaptados às condições edafoclimáticas do local e com custos de manutenção reduzidos. No caso do Algarve, onde a investigação desta dissertação se centra, a disponibilidade hídrica atual e futura, assume um papel preponderante na conceção de espaços verdes, onde as exigências acima mencionadas só poderão ser concretizadas se nos desviarmos de práticas paisagistas convencionais e desenvolvermos estratégias holísticas de gestão e conceção dos espaços verdes que integrem diferentes áreas do conhecimento e não meramente as questões estéticas. Neste contexto, esta dissertação tem como objetivo resgatar práticas paisagistas mais adaptadas e resilientes às condições climáticas do Algarve, reinventando assim o conceito de jardim nesta região de Portugal.
Nesta dissertação apresentam-se dois projetos de jardins xerófilos, em conjunturas distintas (privada e pública). Porém, ambos os projetos consideram espécies vegetais perfeitamente adaptadas a longos períodos de secura climática, que, segunda as previsões de modelos climáticos recentes, terá tendência a se agravar na região do Algarve. Assim, será de sobremaneira importante desenvolver projetos mais sustentáveis, resilientes e tolerantes ao agravamento das condições ecológicas, particularmente às limitações associadas à disponibilidade hídrica.
As suculentas xeromórficas constituem um grupo de plantas, com mecanismos de tolerância ao stress hídrico e com características bem específicas, sendo a suculência uma das mais relevantes. Estudos sobre estes mecanismos são cada vez mais frequentes, o que poderá se mostrar bastante vantajoso na nossa adaptação aos desafios climáticos futuros. Além disso, o seu potencial ornamental é enorme, uma vez que as suas formas arrojadas e panóplia de cores são uma verdadeira explosão sensorial, que aliada às suas características morfológicas e fisiológicas as torna efetivamente espécies de eleição na reconversão ou criação de jardins xerófilos.
Considering the current climate conjuncture, it is a consensus that green spaces in large contemporary urban areas should be increasingly more numerous and simultaneously more sustainable, being adapted to the edaphoclimatic conditions of the site, and with reduced maintenance costs. In the case of Algarve, where the research of this dissertation is focused, the current and future water availability, assumes a preponderant role in the design of green spaces, where the demands mentioned above can only be achieved if we deviate from conventional landscape practices and develop holistic strategies of management and design of green spaces that integrate different areas of knowledge and not merely aesthetic issues. In this context, this research aims to develop landscaping practices more adapted and resilient to the current and future climatic conditions of the Algarve, thus reinventing the concept of landscaping in the south of Portugal. In this work we present, two different approaches of xerophytic landscaping projects (private and public). However, both projects consider species perfectly adapted to long periods of drought, which, according to the predictions of recent climatic models, will tend to worsen in the Algarve. Thus, it will be of paramount importance to develop more sustainable, resilient and tolerant projects to worsening ecological conditions, particularly limitations associated with water availability. The xeromorphic succulents are a group of plants with mechanisms of tolerance to water stress and with very specific characteristics, being succulence one of the most relevant. Studies on these mechanisms are increasingly frequent, which may prove to be very advantageous in our adaptation to future climatic challenges. In addition, their ornamental potential is enormous, since their bold forms and panoply of colours are a veritable sensory explosion, which, combined with their morphological and physiological characteristics, make them the species of choice in the reconversion or creation of xerophilous gardens.
