Stakeholder perceptions of wildfire management strategies as nature-based solut...
Lecina-Diaz, Judit; Campos, João C.; Pais, Silvana; Carvalho-Santos, Cláudia; Azevedo, João; Fernandes, Paulo M.; Gonçalves, João FranciscoIncreased large and high-intensity wildfires cause large socioeconomic and ecological impacts, which demand improved landscape management approaches in which both ecological and societal dimensions are integrated. Engaging society in fire management requires a better understanding of stakeholder perceptions of wildfires and landscape management. We analyze stakeholder perceptions about wildfire-landscape intera...
Climate- and fire-smart landscape scenarios call for redesigning protection reg...
Iglesias, Miguel Cánibe; Hermoso, Virgilio; Campos, João C.; Carvalho-Santos, Cláudia; Fernandes, Paulo M.; Freitas, Teresa R.; Honrado, João P.Integrated management of biodiversity and ecosystem services (ES) in heterogeneous landscapes requires considering the potential trade-offs between conflicting objectives. The UNESCO's Biosphere Reserve zoning scheme is a suitable context to address these trade-offs by considering multiple management zones that aim to minimise conflicts between management objectives. Moreover, in Mediterranean ecosystems, manag...
Mountain farmland protection and fire-smart management jointly reduce fire haza...
Pais, Silvana; Aquilué, Núria; Campos, João C.; Sil, Ângelo Filipe; Marcos, Bruno; Martínez-Freiría, Fernando; Domínguez, Jesús; Brotons, LluísThe environmental and socio-economic impacts of wildfires are foreseen to increase across southern Europe over the next decades regardless of increasing resources allocated for fire suppression. This study aims to identify fire-smart management strategies that promote wildfire hazard reduction, climate regulation ecosystem service and biodiversity conservation. Here we simulate fire-landscape dynamics, carbon s...
Forests as promoters of water ecosystem services: insights from Portugal
Carvalho-Santos, Cláudia; Lopes, Ana Faria; Sil, Ângelo Filipe; Azevedo, João; Nunes, João Pedro; Honrado, João P.Forests provide multiple ecosystem services, with relevance for the ones related to water. It is widely accepted that forests greatly influence the water cycle, promoting evapotranspiration, improving infiltration, reducing surface runoff and consequently soil erosion, although sometimes at expenses of a reduction in total water yield. In fact, forests are targeted for several measures to restore freshwater and...
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 ...
Mapeamento do carbono orgânico do solo numa bacia hidrográfica de montanha
Sil, Ângelo Filipe; Gonçalves, João; Honrado, João P.; Azevedo, João; Ramos, Alice; Fonseca, FelíciaCom o objectivo de modelar e representar cartograficamente a distribuição actual do carbono orgânico no solo na bacia superior do rio Sabor, (i) recolheram-se e processaram-se amostras em 120 unidades de amostragem distribuídas na área de forma otimizada; (ii) modelou-se estatisticamente, com base numa regressão linear múltipla, a relação do carbono solo com um conjunto de variáveis independentes potencialmente...
Using ecosystem services trade-offs analysis to promote the incorporation of ch...
Sil, Ângelo Filipe; Rodrigues, Ana Paula; Nunes, João Pedro; Carvalho-Santos, Cláudia; Honrado, João P.; Alonso, Joaquim; Marta-Pedroso, CristinaThe Montesinho Natural Park in Northeastern Portugal was established in 1979 to preserve a rich and diverse land mosaic maintained by moderate levels of human disturbance. The area has gone through fast social and economic changes that impacted the landscape and its natural values. However, the Natural Park has been unable to incorporate these changes into planning and management. In this work we analysed chang...
Alterações da paisagem e serviços de ecossistema: quantificação e valoração do ...
Sil, Ângelo FilipeNesta dissertação avaliou-se o serviço de ecossistema de regulação climática, através da quantificação, valoração e mapeamento do sequestro e armazenamento de carbono na área da bacia superior do rio Sabor. A avaliação deste serviço baseou-se na interpretação das alterações do uso e ocupação do solo entre 1990 e 2006 e na estimação dos stocks de carbono relativos à biomassa acima e abaixo do solo, matéria orgân...
