- Esperienze estere nella gestione dei castagneti da legno - Castanicoltura da legno in PortugalloPublication . Patrício, Maria SameiroLa coltivazione dei castagno in Portogallo ha unnruolo significativo sia a livello culturale che economico, occupando una superficie che supera i 48. 000 ha con impianti da frutto, denominati "soutos", boschi cedui (4.800 ha ca.) e fustaie per la produzione di legno. Visonoattualmentecirca 10.500 ha di nuovi impianti da legno governati a fustaia in proprietà private mentre il resto delle formazioni adulte di castagno ricadono principalmente su proprietà pubbliche la cui gestione è demandata ai Servizi Forestali: alie fustaie vengono applicati turni di 50-60 anni con conseguente conversione a ceduo dopo il primo taglio di utilizzazione; nei cedui il turno è di 20-25 anni e gli interventi di diradamento consentono di selezionare nel tempo due o tre polloni per ceppaia. Nonostante tali indicazioni, vi è un'evidente carenza nella realizzazione delle cure colturali sia nelle fustaie che nei cedui. II legno di castagno è tradizionalmente molto apprezzato in Portogallo, ma la produzione nazionale è insufficiente a soddisfare la richiesta dei mercato interno e notevole è 1'importazione dalla Francia. Migliorare la qualità dei legname prodotto rappresenta quinai un'opportunità sia per ridurre 1'importazione, sia per valorizzare la filiera dei prodotti non legnosi e fornire servizi aggiuntivi, quali ad esempio lo stoccaggio dei carbonio.
- Fluxos de CO2 do solo num espaço verde urbano: um estudo de caso durante a estação de primavera no norte de PortugalPublication . Silva, Alan Victor; Patrício, Maria Sameiro; Feliciano, ManuelGlobally cities account for more than 70% of CO2 emissions. The potential of urban green spaces as a biotechnology to reduce the net emissions is influenced by the type of vegetation and soil management. Thus, appropriate management of urban soils plays an important role in mitigating climate change, as it affects the biological processes responsible for carbon loss or gain in the soil. The knowledge about the carbon (C) sequestration capacity of grass soils in urban green spaces is still incipient. The study of soil CO2 fluxes is essential to implement more appropriate forms of mitigation in the management of areas with this type of ground vegetation cover. Therefore, this study aimed at investigating CO2 fluxes in a lawn area located in the city of Bragança. CO2 fluxes were measured continuously at a sampling interval of 30 minutes (total number of samples 5523) using the LI-8100A system from LI-COR Biosciences®, together with monitoring of edaphoclimatic and vegetative parameters, during the last month of winter and the tree months of spring. The results showed the importance of herbaceous vegetation in reducing CO2 emissions compared to those that would result from bare soil. However, throughout the observation period, the lawn surface acted as an emitting source with an average magnitude of 1.25 ± 5.31 g C m-2 d-1. The study allowed the identification of phytovolume and soil water availability as the most determining factors in this complex process that underlies the vertical fluxes that occurring at the surface/atmosphere interface. In this sense, management practices related to the frequency and amount of water used in irrigation, as well as the height and frequency of vegetation cutting were identified as key factors on the net exchange of CO2 on these lawn surfaces.
- Perceptions and Challenges of Silvopastoralism in Trás-os-Montes: Insights from the Agricultural SectorPublication . Dias, Estefânia; Ribeiro, Maria Isabel; Castro, MarinaSilvopastoralism is a traditional land-use practice that integrates extensive livestock farming with forestry, generating both economic and environmental advantages. Over time, however, it has declined in relevance and the number of practitioners threatening its continuity and the ecosystem services it provides. This study aims to explore the perceptions of farmers and agricultural stakeholders in the Trás-os-Montes region concerning silvopastoral practices, while identifying the main barriers to their implementation and ways to encourage their adoption. A total of 60 anonymous surveys were carried out for this purpose. The results indicate that respondents see silvopastoralism as highly valuable in terms of wildfire prevention, biodiversity conservation, and sustainable natural resource management. It is particularly regarded as suitable for implementation in mature forest areas and regions with high levels of biomass. Nevertheless, several challenges hinder its adoption, including the lack of technical assistance, low economic returns, and limited awareness of existing research projects in this field. Another significant point raised by this research is the importance of preserving autochthonous livestock breeds, which are deeply connected to silvopastoral practices but increasingly at risk due to their decline. The study also emphasizes the urgent need to rethink rural land management models-especially by developing support mechanisms for producers who engage in silvopastoralism. The future of this practice in Trás-os-Montes will rely not only on the ability of farmers to adapt to modern-day challenges, but also on the broader societal recognition of its environmental benefits and the political will to strengthen and promote it.
