- Enhancing rangeland management through technology: a case study of sheep and goat grazing in Montesinho Natural ParkPublication . Castro, José; Fellahi, Mohamed; Benmellouk, Issam; Castro, Marina; Yessef, MohammedThe advent of advanced technologies offers unprecedented opportunities to improve the sustainability and resilience of rangeland management. This study examines the application of Global Navigation Satellite Systems (GNSS) in monitoring and optimizing the shepherding journeys of sheep and goat pastoralists throughout the rangelands of Montesinho Natural Park, Portugal. Two distinct flocks—sheep and goats—were each equipped with a GNSS collar to monitor their routes across seasons and landscapes from April 2022 to March 2023. The study yielded 186 grazing journeys for the sheep flock and 232 for the goats. The data collected were subsequently analyzed using Geographic Information Systems (GIS) and Principal Component Analysis (PCA). These analytical methods were employed to discern patterns and correlations between grazing journeys and environmental variables, including altitude, topographic wetness, and land use types. The land use types examined encompassed orchards, oak forests, and shrublands. The study elucidates marked discrepancies in the shepherding landscapes of the two species under investigation. The flock of sheep exhibited a distinct preference for agroforestry zones, demonstrating heightened sensitivity to climatic fluctuations, particularly during extreme temperatures. In such conditions, the sheep sought refuge in oak woods, chestnut groves, and riparian forests. Conversely, the goats demonstrated a greater utilization of rangelands and forestlands, indicative of their superior adaptability to varying environmental conditions. Additionally, seasonal variations were pronounced, with both species modifying their grazing strategies in response to the dynamic environmental changes.
- Silvopastoralism as an Agroforestry Systems: Survey Analysis of Perceptions in the Agricultural Sector of Trás-os-Montes region, PortugalPublication . Dias, Estefânia; Ribeiro, Maria Isabel; Castro, MarinaSilvopastoralism, as a traditional agroforestry practice that combines extensive livestock production with forestry, offering both economic and environmental benefits, has been losing prominence, thus compromising the ecosystem services it provides. This research arises from the need to understand the obstacles to its adoption in Trás-os-Montes, a region marked by vulnerability to rural wildfires and demographic desertification. Despite the scientific recognition of the environmental and social benefits of silvopastoralism, there remains a significant gap in knowledge regarding the perceptions and challenges experienced by producers in its implementation. Based on the SILFORE project, this study involved 60 face-to-face surveys with various stakeholders in the agroforestry sector in the Trás-os-Montes region. The objective was to identify perceptions of the usefulness of silvopastoralism and the main constraints to its application. The data collected were statistically analyzed using frequency measures and measures of central tendency. The results reveal a clear appreciation for the role of silvopastoralism in wildfire prevention, biodiversity conservation, and the preservation of native breeds. However, factors such as low economic profitability, lack of technical support, and the absence of tailored public policies compromise its viability. It is concluded that the revitalization of silvopastoralism depends on integrated strategies involving technical assistance, institutional recognition, and the valorisation of associated products—contributing to the resilience of rural territories.
