Métodos de Mapeamento Digital do Solo para monitorização de parâmetros edáficos...
Gonçalves-Rodrigues, Tânia; Silva, Renato; Mouta, Nuno; Barros, Cristiano; Mendes, Susana; Paredes, Cláudio; Valín, Isabel; Charters, LourençoO solo constitui um recurso natural complexo e central para a produção agrícola e a qualidade ambiental dos agroecossistemas. O mapeamento e modelação detalhada das propriedades do solo por deteção remota permitem desenvolver ferramentas e conhecimento úteis para uma agricultura sustentável e responsável. Neste contexto, recolheram-se dados multiespectrais a partir do Sentinel-2 e de um veículo aéreo não tripul...
Fine-tuning the BFOLDS fire regime module to support the assessment of fire-rel...
Sil, Ângelo Filipe; Azevedo, João; Fernandes, Paulo M.; Alonso, Joaquim; Honrado, João P.Fire simulation models are useful to advance fire research and improve landscape management. However, a better understanding of these tools is crucial to increase their reliability and expansion into research fields where their application remains limited (e.g., ecosystem services). We evaluated several components of the BFOLDS Fire Regime Module and then tested its ability to simulate fire regime attributes in...
Farmland abandonment decreases the fire regulation capacity and the fire protec...
Sil, Ângelo Filipe; Fernandes, Paulo M.; Rodrigues, Ana Paula; Alonso, Joaquim; Honrado, João P.; Perera, Ajith H.; Azevedo, JoãoThis study explored and applied the concepts of Fire Regulation Capacity (FRC) and Fire Protection Ecosystem Service (FPES) in the assessment of the effects of landscape change in a mountain fire-prone landscape in Portugal. We adopted a modeling and simulation approach using BFOLDS-FRM with landscape data for years 1990 and 2006 (observed) and with three landscape scenarios for 2020. Proxy indicators for FRC (...
Exploring the concept of fire protection ecosystem service in changing forested...
Sil, Ângelo Filipe; Fernandes, Paulo M.; Rodrigues, Ana Paula; Alonso, Joaquim; Honrado, João P.; Perera, Ajith H.; Azevedo, JoãoLandscapes and ecosystems play an important role in fire regulation and in the mitigation of potential negative effects of extreme fire events. Fire protection regulated by ecosystems and landscapes can thus be considered as an ecosystem service with significant benefits for humans’ safety, health and economy. Although fire is an important ecological process in most of the planet, fire regulating and protection...
Analysing carbon sequestration and storage dynamics in a changing mountain land...
Sil, Ângelo Filipe; Fonseca, Felícia; Gonçalves, João; Honrado, João P.; Marta-Pedroso, Cristina; Alonso, Joaquim; Ramos, Maria; Azevedo, JoãoWe assessed the effects of landscape change on the climate regulation ecosystem service in a mountain river basin of Portugal, through the quantification, valuation and mapping of carbon sequestration and storage. The analyses were based on land use and land cover (LULC) changes that took place between 1990 and 2006 and on expected changes defined by three LULC change scenarios for 2020. We used the Integrated ...
Trade-offs and synergies between provisioning and regulating ecosystem services...
Sil, Ângelo Filipe; Rodrigues, Ana Paula; Carvalho-Santos, Cláudia; Nunes, João Pedro; Honrado, João P.; Alonso, Joaquim; Marta-Pedroso, CristinaThis study explored the effects of landscape change on the provision of ecosystem services in a mountain area in northern Portugal, in particular the trade-offs and synergies between services in 2 categories: provisioning and regulating. Services were assessed for 1990 and 2006 and projected for 2020 under 3 scenarios, both biophysically and economically, based on modeling and published and unpublished statisti...
Assessment of fire hazard regulation ecosystem service in a mountain area in no...
Sil, Ângelo Filipe; Fernandes, Paulo M.; Marta-Pedroso, Cristina; Alonso, Joaquim; Honrado, João P.; Perera, Ajith H.; Azevedo, JoãoThe fire hazard regulation ecosystem service (ES) is the capacity of ecosystems and landscapes to maintain the frequency and intensity of fire events. Assessing how ecosystems and landscapes regulate fire hazard is of utmost importance to avoid or mitigate negative environmental and socioeconomic impacts as well as to understand the benefits that human societies can obtain and their value. This study aimed to u...
Ecosystem services and landscape change: quantification and valuation of carbon...
Sil, Ângelo Filipe; Marta-Pedroso, Cristina; Alonso, Joaquim; Honrado, João P.; Azevedo, JoãoForest ecosystems provide multiple services including climate regulation through e.g. Carbon Storage and Sequestration (CSS). However, the dynamics of this Ecosystem Service (ES) is strongly influenced by Land Use/ Land Cover (LULC) changes. In order to understand the influence of these changes in the provision of this ES through time, we quantified, mapped and valued CSS in the Sabor River’s upper basin (north...
Tradeoffs among provisioning and regulation ecosystem services in mountain area...
Sil, Ângelo Filipe; Rodrigues, Ana Paula; Nunes, João Pedro; Carvalho-Santos, Cláudia; Honrado, João P.; Alonso, Joaquim; Marta-Pedroso, CristinaMountain areas in Portugal provide a diversity of essential ecosystem services, including many provisioning and regulating services. These areas have gone through fast and significant landscape change over the past decades mainly driven by depopulation and agriculture abandonment. To understand how these changes affect the provision of ecosystem services (ESs) in mountain areas in Portugal and to gain insight i...
Efeitos da alteração da paisagem no fornecimento de serviços de ecossistema na ...
Sil, Ângelo Filipe; Rodrigues, Ana Paula; Nunes, João Pedro; Carvalho-Santos, Cláudia; Honrado, João P.; Alonso, Joaquim; Marta-Pedroso, CristinaA capacidade dos ecossistemas fornecerem serviços é determinada pela sua estrutura e processos biofísicos inerentes bem como por processos de outras naturezas que ocorrem a outras escalas. As alterações no uso e ocupação do solo apresentam-se como um importante processo em curso com potenciais efeitos no fornecimento desses serviços. Neste trabalho analisou-se o impacto das alterações no uso e ocupação do solo ...
