- Assessing beekeeping potential in a Portuguese area with honey Protected Designation of OriginPublication . Silveira, Carlos; Roque, Natália; Fernandez, Paulo; Anjos, O.; Vilas-Boas, MiguelThis study aims to assess the beekeeping potential in a Portuguese area with honey protected designation of origin (PDO) following a multi-criteria decision analysis (MCDA) for supporting beekeepers in the selection of the best locations for apiaries, thus maximizing honey production and reducing the risk of bee colony losses.
- Integrating multicriteria decision analysis for beekeeping suitability: insights from a Portuguese honey PDO landscapePublication . Silveira, Carlos; Roque, Natália; Bruno Leitão; Fernandez, Paulo; Anjos, O.; Vilas-Boas, MiguelBeekeeping plays a vital role in biodiversity conservation and local economy development, as bees are key pollinators of numerous wild plant species and agricultural crops. Accordingly, understanding the suitability of rural territories is essential to provide an overview on bee activity and support the development of more sustainable beekeeping practices. This study presents an enhanced multicriteria approach for mapping beekeeping suitability, applied to a Portuguese region renowned for its honey with Protected Designation of Origin (PDO). The methodology integrates topographic, environmental and climatic criteria closely linked to bee ecology, whose relevance was prioritised in each category following expert perceptions and the Analytic Hierarchy Process (AHP). For these criteria, high-quality spatial data were compiled and processed using Geographic Information Systems (GIS) to evaluate landscape favourable conditions and limiting factors for beekeeping. Results indicate a comparable and significant influence of environmental and climatic criteria (43% each) relative to topographic ones (14%). Within each category, hillside exposure (63%), flora (53%) and rainfall (50%) contributions are particularly remarkable in defining the beekeeping suitability. When crossing the final suitability map with the apiary influence range, most apiaries were found in areas classified as very high suitability. This information provides valuable insights for beekeepers and policymakers, helping to optimize the beekeeping management and enhance the honey quality, particularly in PDO areas. Moreover, the proposed approach offers a scalable and adaptable framework that can be applied to other regions with beekeeping potential.
- Using analytic hierarchy process to assess beekeeping suitability in Portuguese controlled areas : a first approachPublication . Roque, Natália; Fernandez, Paulo; Silveira, Carlos; Vilas-Boas, Miguel; Anjos, O.Beekeeping management is greatly influenced by spatial factors (e.g., land use/land cover, roads, or electrical energy networks), so GIS are a powerful tool to overlap and relate a variety of spa- tial data levels and, consequently, a very useful tool for beekeeping activity planning. This study was developed within the intervention area of three controlled zones managed by Portuguese Beekeepers Associations. The methodology, based on multi-criteria decision analysis, integrates several criteria, such as hydrographic networks, road networks, soil occupation, solar radiation, and electromagnetic radiation sources. These criteria were proposed and evaluated through online questionnaires carried out with beekeepers. Concerning the selected criteria and the respective geographical data, the most relevant were land use/land cover and water availability, with a significance of 44% and 24%, respectively. The beekeeping suitability map enabled us to evaluate the degree of compliance for the actual location of apiaries, with 60% of the apiaries being installed in high potential areas. In the context of beekeeping planning, the potential of the techniques applied seems to be an important tool for optimizing the location of apiaries and the profitability of beekeeping.
