During the 2025 financial year, the activities were carried out as part of project PID2024-162966OA-I00 (PaRaPel), with a view to achieving the objectives set out in "Plan Generación de Conocimiento 2024". These actions have contributed to the progress of the planned lines of work through the completion of technical tasks, inter-institutional coordination, and the development of interim results that strengthen the project’s implementation and ensure its continuity in subsequent phases. It is also worth highlighting the project’s marked cross-cutting nature, which has facilitated the coordination of activities that go beyond the initially defined objectives, integrating multidisciplinary approaches and fostering synergies between different fields of knowledge. This cross-cutting dimension has made it possible not only to optimise the use of interim results, but also to generate new complementary lines of work, reinforcing the project’s scientific and technical impact and its capacity to adapt to emerging challenges within the framework of the Plan. Consequently, the project’s development is not limited to the achievement of the specific objectives set out, but contributes more broadly to the advancement of knowledge and the consolidation of scientific collaboration networks of high strategic value.
