From badland to bushland? Analysis of geomorphic process dynamics and vegetation development in a sub-humid calanchi area based on high-resolution UAS data (2014–2024)
A decade-long study of the Val d'Orcia badlands reveals a transition toward landscape stabilization, driven by intrinsic geomorphic dynamics rather than climatic shifts. High-resolution UAS data (2014–2024) showed a 50% reduction in water erosion despite stable erosion rates, indicating a shift from high-frequency to high-magnitude, event-driven processes. The research also documented an unprecedented subsurface deformation process—gravitational bulging—caused by water infiltration and clay swelling. Vegetation establishment in depositional areas further contributed to stabilization, suggesting the system operates near a geomorphic threshold under normal precipitation conditions.
Large dams and small reservoirs: co-modeling water storage strategies in a Mediterranean catchment under a changing climate
Future water storage in Mediterranean reservoirs is projected to decline by up to 21% due to climate change, with small agricultural reservoirs (SmARs) being more vulnerable than large dams. This decline results from reduced precipitation and increased evaporation, alongside decreased seepage losses that reduce aquifer recharge. The study, conducted within the Val d'Orcia Rural Living Lab using a co-modeling approach, simulates various water storage strategies under current and projected future climates, considering five climate models. While large dams face significant evaporation losses, SmARs are more threatened by reduced inflows. The research emphasizes the need for comprehensive, participatory analysis to inform best watershed management practices, highlighting that local actor involvement is crucial for successful adaptation.
Pliocene Alluvial to Marine Deposits of the Val D’Orcia Basin (Northern Apennines, Italy): Sequence Stratigraphy and Basin Analysis
The Val d'Orcia Basin, located in the Northern Apennines of Italy, was identified as an inherited depression formed by erosion during the Late Miocene-Early Pliocene transition. This study reveals that its Pliocene depositional history was primarily controlled by relative sea-level changes, leading to the recognition of three distinct depositional sequences (Vd3a-c). The Vd3a sequence records marine ingression and subsequent highstand, while Vd3b and Vd3c sequences reflect progressive basin widening. Notably, bioclastic deposits in the Vd3c sequence suggest potential climatic influence on sedimentation. The research employs a sequence stratigraphic approach to analyze these deposits, providing insights into the basin's geological evolution.
La gestione e l'impatto dei siti UNESCO:monitoraggio e valutazione dei siti italiani nel dibattito internazionale
A new model for assessing the management and impact of UNESCO World Heritage Sites (WHS) on local territories has been developed, focusing on qualitative aspects such as knowledge, conservation, valorization, and communication. The study highlights significant social and economic impacts, particularly in cases like the viticultural landscapes of Langhe, Monferrato, and Roero, where the candidacy process itself became a public phenomenon. By analyzing multiple Italian WHS—including Val d'Orcia, Naples, Genoa, Florence, Pienza, Royal Residences, Val Camonica, and Alberobello—the research evaluates governance strategies and their long-term effects on heritage preservation and territorial development. The model synthesizes international frameworks with local case studies to provide a comprehensive understanding of WHS management from inception to sustained impact.
The Extra-urban Cultural District: An Emerging Local Production System: Three Italian Case Studies
Research identifies three key levers—cultural heritage, natural amenities, and local governance—that drive the success of extra-urban cultural districts (E-UCDs). Unlike urban clusters, E-UCDs thrive by leveraging rural landscapes and traditions, offering a model for sustainable development. The study analyzes three Italian case studies: Cinque Terre, Val d'Orcia, and Ravello, combining theoretical frameworks with empirical data to demonstrate how these levers interact in practice. Findings highlight the potential of E-UCDs as tools for rural revitalization, bridging cultural valorization with economic growth.
Reclaiming Catherine of Siena: Literacy, Literature, and the Signs of Others by Jane Tylus
Jane Tylus' work 'Reclaiming Catherine of Siena: Literacy, Literature, and the Signs of Others' challenges historical skepticism surrounding Catherine of Siena's literacy, establishing her as a pioneering Italian writer. The study employs a meticulous analysis of Catherine's letters, dictated works from Pisa, and her later writing in Rome, alongside hagiographic texts by Raymond of Capua and Tommaso Caffarini. Tylus argues that Catherine learned to write during her time in the Val d'Orcia in 1377, using Tuscan vernacular deliberately, thereby positioning her alongside Dante and Petrarch in the development of Italian literature. The research also examines the preservation and presentation of her literary legacy, including Girolamo Gigli's 18th-century defense and Aldus Manutius' 16th-century edition. Through linguistic analysis, Tylus reconstructs Catherine's self-understanding as both a speaker and writer, offering new insights into her authorship and the cultural significance of her work.
