The Municipality of Ajdovščina has been facing challenges related to soil erosion and landslides on steep non-urban areas for several years. Due to the increasing impacts of climate change and human interventions in space, these phenomena are occurring more frequently and with greater intensity. The consequences are most evident on agricultural land, while also affecting municipal and transport infrastructure.
Within the project, significant progress has been achieved in addressing these challenges. A comprehensive project documentation has been prepared, providing a key professional basis for understanding erosion processes and for planning effective mitigation and preventive measures. The documentation covers the pilot area of the Vipava Hills and its hinterland, as well as three vineyard micro-locations identified through analysis as the most erosion-prone areas: Zavino, Velike Žablje and Plače.
Among the key achievements is the preparation of project documentation for the rehabilitation of a vineyard in the village of Zavino. As part of these activities, a hydrological-hydraulic study, a geological-geomechanical study, and detailed design documentation (PZI) were developed, enabling the implementation of concrete mitigation measures.
The project has also contributed to improved stormwater management through flow measurement studies and the hydraulic optimisation of the drainage system. In addition, a geological-geotechnical and hydrogeological study was prepared for the wider Vipava Hills area. An important outcome of the project is also the establishment of a unified spatial data basis using LiDAR and photogrammetric surveying, enabling more precise terrain analysis and monitoring of spatial changes.
