Management and sustainable development in cooperative and social economy enterprises. A literature review on SDGs implementation (2015–2023)
The United Nations defined the Sustainable Development Goals (SDGs) in 2015. As a result, an increasing number of companies have integrated sustainable development practices into their activities with the aim of contributing to the SDGs achievement. Similarly, the SDGs implementation becomes an opportunity for companies, since the creation of social and environmental value simultaneously increases economic and financial value. The contribution of…
Modern vegetation and its pollen spectra in the Cantabrian mountains, northern Iberian Peninsula, compared with fossil pollen records
The study of the pollen rain from modern vegetation has greatly improved the interpretation of pollen diagrams and our understanding of ancient plant communities. In this study, 76 pollen samples were studied from various vegetation types in Cantabria, northern Iberian Peninsula. The pollen signals of the main taxa were compared to their estimated spatial coverage at various scales (100 m, 1 km and 5 km from the sampling point) using vegetation m…
Une nouvelle dimension à l’analyse palynologique. Le potentiel des pollen washes pour une meilleure compréhension de l’utilisation des plantes
Alimentation, pharmacopées, rituels funéraires... Les relations interdépendantes développées au fil des millénaires entre les sociétés et les plantes taraudent les spécialistes de l’analyse des grains de pollen et des spores de végétaux depuis les années 1960 (Roux 1967). Délaissant les reconstitutions paléoenvironnementales — souvent l’apanage des investigations en séquences naturelles tourbeuses ou lacustres —, les palynologues ambitionnent ici…
Landscape footprints of peopling and colonisation from the Late Bronze Age to Antiquity in the coastal hinterland of Emporion-Emporiae , NE Iberia
The Empordà plain attests to a remarkable mixture of Late-Holocene cultural exchanges and colonial processes. This includes the founding of Emporion, the earliest Greek colony in Iberia, and of the Roman city of Emporiae. This study aims at assessing landscape changes related to indigenous and colonial settlement in this unique scenario where the shaping of cultural landscapes occurred within a dynamic coastal ecosystem. We carried out a high-tem…
Neanderthal plant use and stone tool function investigated through non-pollen palynomorphs analyses and pollen washes in the Abri du Maras, South-East France
Humans take control of fire-driven diversity changes in Mediterranean Iberia’s vegetation during the mid–late Holocene
Fire regime changes are considered a major threat to future biodiversity in the Mediterranean Basin. Such predictions remain uncertain, given that fire regime changes and their ecological impacts occur over timescales that are too long for direct observation. Here we analyse centennial- and millennial-scale shifts in fire regimes and compositional turnover to track the consequences of fire regime shifts on Mediterranean vegetation diversity. We e…
Advancing the Analysis of Past Human/Plant Relationships
The ‘pollen washes’ technique, based on the analysis of the pollen embedded in the porous surface of archaeological artefacts, is developed for investigating past plant usage and consumption and to characterize the functionality of artefacts related to plant processing, gathering and storage. The research presented results in relevant methodological improvements of this technique, which has never previously been applied on materials from European…
Historic and Holocene Environmental Change in the San Antonio Creek Basin, Mid-coastal California
Using a combination of pollen, non-pollen palynomorphs (NPPs) and charcoal particle stratigraphies from sediment cores from two sites, along with historical records, we reconstructed paleoenvironmental change in mid-coastal California. The San Antonio Creek section contains a discontinuous, Holocene-length record, while Mod Pond includes a continuous late Holocene record. Together the records allow for interpretation of most of the present interg…

Shifting occupation dynamics in the Madriu–Perafita–Claror valleys (Andorra) from the early Neolithic to the Chalcolithic
The Madriu–Perafita–Claror valleys (MPCV) (Eastern Pyrenees, Andorra) were the focus of a multidisciplinary microregional landscape research project that aimed to study the long term shaping of this UNESCO World Heritage Site in the category of cultural landscape. The study area is situated on a glacial modelled high mountain environment ranging from 1250 to 2800 m.a.s.l. Multidisciplinary approaches integrating archaeology and palaeoenvironment …
Water management and land-use practices from the Iron-Age to the Roman period in Eastern Iberia
Holocene and historical vegetation change and fire history on the north-central coast of California, USA
Pollen, non-pollen palynomorphs (NPPs), and charcoal particle stratigraphies are used to determine environmental change at Glenmire, Point Reyes Peninsula, northcentral coastal California, over the last c. 6200 years. Pollen was not preserved in early Holocene sediments when climate was drier than present. However, groundwater tables rose after c. 6200 cal. BP, allowing for greater subsequent preservation of organic matter. Middle and late Holoce…

Pitch production during the Roman period
The authors' research project in the Pyrenees mountains has located and excavated Roman kilns for producing pitch from pine resin. Their investigations reveal a whole sustainable industry, integrated into the local environmental cycle, supplying pitch to the Roman network and charcoal as a spin-off to the local iron extractors. The paper makes a strong case for applying combined archaeological and palaeoenvironmental investigations in upland area…
La Carència (Valencia, España) y su territorio Resultados de la aplicación de metodologías digitales
'La Carència. Chronological and urban change. Evaluation in its territorial context' is an archaeological project whose application of digital methodologies to the study of la Carència Ibero-Roman oppidum and its territory has been prominent during the last ten years. This application has been twofold: archaeological research has employed GIS analyses, photogrammetrical modelling of past landscapes and multispectral imagery analysis. Scientific d…
Testing micro-regional variability in the Holocene shaping of high mountain cultural landscapes
Tracing the history of highland human management in the eastern Pre-Pyrenees
Although high mountain areas have traditionally been viewed as predominantly grazing areas, with low population and a high degree of land-use stasis, recent research suggest that land-use complexity and change over time has been underestimated. This interdisciplinary palaeoenvironmental analysis has been carried out on the Pradell calcareous fen, located in the eastern Pre-Pyrenees (Spain) at 1975 m a.s.l., and it comprises different environmenta…
Legacies of Change
Human conceptions of landscape have influenced the shaping of landscapes as much as landscape configurations have modelled human perceptions. In this article a new theoretical approach to long‐term cumulative landscape change is tested on the Garraf Massif (Baix Llobregat, north‐eastern Spain). Thanks to its ancient occupation, physical character and location near to the city of Barcelona, the area provides a good illustration of how human‐induce…
