*Computer-based data collection & modelling*
The first project stage (Data Collection) consisted of using GIS to support a preliminary retrogressive analysis of the two case studies. The GIS-HLC dataset was developed by combining modern and historic cartography with remotely-sensed imagery made available by regional authorities. These sources enabled the creation of a multi-temporal map of historic landscape changes in the two regions of interest. Data processing comprised the second stage of the HiLSS project. Firstly, the GIS-HLC dataset was explored with two spatial statistical tools: Local Indicators for Categorical Data (LICD) and Point Pattern Analysis (PPA). Secondly, the project focussed on assessing the impact of historic landscape change on soil erosion and degradation with the RUSLE equation.
*Fieldwork analysis*
Based on the results of the GIS-HLC mapping process, the most promising sites were identified in both regions of interest.
The first field campaign (October 2021) focussed on the Italian case study, Vetto d'Enza (Emilia Romagna region, Italy). Here the results of OSL-PD provide secure construction dates in the Middle Ages (10th - 14th century CE) for most of the historic boundaries examined in the area, with evidence for further development and subdivision of the systems in the Early Modern period (15th - 18th century CE). Moreover, the OSL profiles from the stone-walled terraces also demonstrate how effectively such features have contributed to soil conservation over extended periods. The second field campaign (May 2022) was carried out in the second case study ( Samos, Galicia - Spain). OSL-PD preliminary results indicate that the 17th century AD was a key era in the transformation of the monastery’s immediate surroundings, with the construction of large and complex terrace systems on both sides of the valley.
*Results Dissemination*
Improving communication between stakeholders using an effective dissemination strategy was a key aspect of the project. Relevant stakeholders were divided in two main groups: academic researchers and non-academic public. To ensure effective actions in each study areas, the stakeholders in each case-study was assessed to develop an effective and targeted communication strategy. The principal method for scientific dissemination was through peer-reviewed journals and conferences. At the end of the fieldwork campaigns, two open dialogue workshops were organized in each study area to discuss how the results can support landscape management and planning. Each workshop was organised in partnership with regional partners (Italian Alpine Club and Centro de Investigación Interuniversitario das Paisaxes Atlánticas Culturales) with the aim of engaging local communities with sustainability and historic landscapes. Furthermore, the project's blog was developed in collaboration with International Traditional Knowledge Institute (ITKI) a UNESCO initiative to promote sustainable solutions using traditional knowledge through interactive engagements. The project HiLSS has enlisted the ITKI's Creative Knowledge Platform (CKP), a tracing story-telling software for cultural promotion. Finally, the HiLSS's Twitter profile was constantly updated during the project's phases.
