- Beyond cadaster: landowners and land fragmentation—insights from a case studyPublication . Ferreira da Silva da Costa Freitas, Maria de Belém; Teixeira, Miguel; Rolo Antunes, Carla Maria; César Ribeiro, Henrique; Partidário, Maria do RosárioLand management is a relevant problem in rural areas all over the world, conditioning the planning decisions and the applicability of planning instruments. This study evaluates the limitations of cadastral data in representing land fragmentation and management patterns in wild-fire-prone landscapes, using Alferce (Portugal) as a case study with broader international relevance. Similar challenges—fragmented ownership, incomplete land registries, and increasing wildfire risk—affect many regions worldwide, particularly across the Mediterranean basin and other fire-prone rural landscapes. A mixed-methods approach combines cadastral data with field data from 23 landowners producing two datasets: cadaster-only and ownership-enhanced. Fragmentation is assessed using Simmons and Januszewki indices, supported by spatial analysis (Kernel Density and Moran’s I). Results show that cadastral data alone significantly overestimates fragmentation. While parcel-based analysis suggests a highly fragmented landscape, incorporating ownership information reveals more aggregated management structures. The 23 landowners manage 1247 ha (≈13% of the area), forming a “keystone” group with strong potential for coordinated land management and fire prevention. Higher fragmentation is associated with population centers. These findings demonstrate that cadastral units do not reflect functional management units and considerations about property fragmentation are biased by the lack of information about the owners, a key theoretical contribution with implications beyond Portugal. For policymakers, integrating ownership data and targeting key land managers can improve land use planning and wildfire mitigation and, overall, the sustainability of the territory. Despite limitations (small sample), the approach is transferable to other regions facing similar structural constraints.
- Using participatory mapping to Foster Community-Based disaster risk reduction in Forest Fire-Prone Areas: the case of Monchique in PortugalPublication . Partidário, Maria; Saad, Guilherme; Monteiro, Margarida B.; Dias, Joana; Martins, Rute; Ramos, Isabel Loupa; Ribeiro, Henrique; Teixeira, Miguel; Costa Freitas, M. B.; Antunes, CarlaLocal knowledge and communities’ active role in disaster risk areas are recognized in the literature as key conditions to better understand risks, enhance adaptive capacities and foster local resilience. A participatory action research project in forest fire-prone areas in Monchique, Portugal, is aligned with the literature and adopts participatory mapping as a method that can bring evidence to the importance of local knowledge and communities’ agency. In the BRIDGE Project, different types of knowledge are integrated, triggering local/collective agency and fostering a forest fire community-based disaster risk reduction (CBDRR) approach. An innovation laboratory (InnoLab) provides the space for dialogue and knowledge sharing for different actors that manage forest territories. In the InnoLab, participatory mapping is used as a method to engage landowners where risk factors and local vulnerabilities were identified. Their active engagement enabled a collective perception in the assessment of vulnerability and led to the identification of strategic measures for risk reduction. This paper shares the process and outcomes of this participatory mapping, highlighting the benefits of a community approach and the importance of local knowledge and practices as recognized in the literature. It also reveals how the active role of local stakeholders can help drive a CBDRR process.
