Máquina para a remoção de subprodutos do solo em pomares
Dias, António Bento; Garcia, Ana; Rasteiro, Carla; Isaque, Sónia; Gomes, Rafael; Batista, M.J.; Antunes, Rosário; Azevedo, João; Luz, João P.Embora a colheita seja o ponto alto do ciclo anual de produção em fruticultura, nem todos os frutos são retirados do pomar, ficando depositados no solo após a colheita. Tratam-se de frutos sem qualidade comercial que acabam por se decompor durante o período de repouso vegetativo, embora também podem ser fonte de proliferação de pragas e doenças. Na região Oeste, a campanha de produção de pera de 2014/2015 carac...
Relationships between amount and configuration indicators in real-world landsca...
González-Ávila, Sergio; Martín, Belén; Ortega, Emilio; Azevedo, JoãoUnderstanding the role of habitat loss and fragmentation per se is crucial to generate relevant knowledge for habitat management. In the case of forest species, this can be achieved by measuring forest amount and configuration metrics at the landscape scale, including their relationship. We aimed to characterize the relationship between forest amount and configuration metrics in real-world landscapes of an exte...
Increased policy ambition is needed to avoid the effects of climate change and ...
Pedersen, Jiesper Strandsbjerg Tristan; Dias, Luís Filipe; Kok, Kasper; Vuuren, Detlef van; Soares, Pedro M.M.; Santos, Filipe Duarte; Azevedo, JoãoThe Paris Agreement's goal of limiting global warming hinges on forest carbon sequestration as a key in several national strategies. However, Portugal's rising forest fire occurrences threaten its ability to meet ambitious 2030 and 2050 carbon sequestration targets. Considering fire and forest trends, this study aims to quantify whether Portugal can reach its carbon sequestration ambitions as stated in its 2030...
Hakea decurrens invasion increases fire hazard at the landscape scale
Gerber, Dionatan; Azevedo, João; Nereu, Mauro; Oliveira, Aline Silva de; Marchante, Elizabete; Jacobson, Tamiel Khan Baiocchi; Silva, Joaquim S.Hakea decurrens subsp. physocarpa is an invasive fire-adapted shrub of Australian origin that is quickly expanding in Portugal with potential impacts on fire behavior and fire regime. In this study we examined the effects of H. decurrens on fire hazard by assessing fire behavior indicators at the landscape scale, using a modeling and simulation approach. Six fuel models for H. decurrens were developed through f...
Fire regime attributes shape pre-fire vegetation characteristics controlling ex...
Beltrán-Marcos, David; Suárez-Seoane, Susana; Fernández-Guisuraga, José Manuel; Azevedo, João; Calvo, LeonorDesigning effective land management actions addressed to increase ecosystem resilience requires us to understand how shifting fire regimes are shaping landscapes. In this study, we aim to assess the link between fire regime and pre-fire vegetation biophysical characteristics (type, amount, and structure) in controlling extreme fire behavior across Atlantic-Transition-Mediterranean bioregions in Spain marked by ...
Trajectories and drivers signalling the end of agricultural abandonment in Trás...
Imbrechts, Lien; Azevedo, João; Verburg, PeterAgricultural abandonment has given rise to novel landscape dynamics worldwide. This paper investigates abandonment and post-abandonment dynamics in continental Portugal as a hotspot of landscape change. We mapped the spatial patterns and drivers of recent (1995–2018) land use changes in a remote mountainous region as post-abandonment trajectories, based on detailed land use/land cover data made available by the...

Will fire-smart landscape management buffer the effects of climate and land-use...
Sil, Ângelo Filipe; Azevedo, João; Fernandes, Paulo M.; Honrado, João P.Long-term farmland abandonment has increased fuel build-up in many Euro-Mediterranean mountainous regions. The high fuel hazard in these landscapes, combined with ongoing climate change, is increasing the frequency of extreme wildfires, thus altering contemporary fire regimes. Mitigating the loss of the landscape’s capacity to regulate large and intense fires is crucial to prevent future harmful effects of fire...
BEIRA BAIXA’S BLOOD PRESSURE PROGRAM – COUNTY OF CASTELO BRANCO
Pinto, Sofia; Coelho, Patrícia; Azevedo, João; Rodrigues, Francisco; Pires, JoanaIntroduction: Hypertension is a common and relevant risk factor in the development of several cerebrovascular diseases. The high prevalence of this pathology, associated with other complications, demonstrates the importance of carrying out this study. Objective: The main objectives of this study were to assess the blood pressure of the population of Castelo Branco, guide hypertensive respondents, warn of the ri...
Development of a Machine to Remove By-products with Brown Spot Disease Inoculum...
Dias, António B.; Garcia, Ana; Rasteiro, Carla; Isaque, Sónia; Gomes, Rafael; Batista, Maria J.; Antunes, Rosário; Martins, M. Carmo; Azevedo, JoãoIn Portugal pear production is located in the Midwest region, occupying an area of about 11000 ha, under the registered designation of origin of “Pera Rocha do Oeste”. In recent years, the incidence of brown spot disease (Stemphylium vesicarium) increased, with considerable losses to the growers due to the depreciation of pears both in the orchards and in refrigeration chambers. The control of the disease based...
