Holocene environmental change and human impact in NE Morocco: Palaeobotanical evidence from Ifri Oudadane

The littoral site of Ifri Oudadane is one of the most important recently excavated sites in the Mediterranean Maghreb. The shelter presents Epipalaeolithic and Neolithic layers and therefore offers the possibility to investigate the Neolithic transition in the region. Besides introducing the archaeological context, this paper focuses on palaeobotanical data in order to reconstruct Holocene environmental change and human use of plant resources for the period c. 11 to 5.7 ka cal. BP. Results show intense landscape transformations resulting from anthropic and climatic factors. First human occupations start at the beginning of the Holocene with favourable conditions in this otherwise harsh semi-arid stretch of land. A wooded environment with evergreen sclerophyllous oaks and riparian forests is documented and exploited by hunter-gatherers. From c. 7.6 ka cal. BP farming activities are well attested together with significant human impact, herding pressure and a progressive decline of arboreal components. After 6.6 ka cal. BP conditions become less favourable and markers for aridity increase. Riparian taxa disappear (Alnus) or decrease (Fraxinus, Populus, Salix); shrubs (Tamarix) and grasses (Artemisia) increase with a degradation of forest into shrubland (macchia). During 6.6 and 6.0 ka cal. BP there is a general occupation gap in arid and semi-arid Morocco and evidence for that change is also found in the alluvial deposits of the Moulouya, NE Morocco. Indicators for food production decrease at the same time and the site is abandoned during the first half of the 6th millennium cal. BP.

Beyond nature: The management of a productive cultural landscape in Las Médulas area (El Bierzo, León, Spain) during pre-Roman and Roman times

Abstract This article focuses on the analysis of plant remains (seeds/fruits, charcoal, pollen, spores, and non-pollen palynomorphs) from two archaeological sites (pre-Roman and Roman) located in Las Médulas, a cultural landscape, in the northwestern part of the Iberian Peninsula. The article explores the way the communities living in the area managed their environment and the impact of productive activities on the landscape. This research has shown the multiplicity of needs this landscape satisfied and the various ways these communities managed the surrounding environment through different productive activities (agriculture, animal husbandry, and mining amongst others).

A palaeoenvironmental and palaeoeconomic approach to the Early Middle Age record from the village of Gasteiz (Basque Country, Northern Iberian Peninsula).

An integrated archaeobotanical study carried out in the medieval village of Gasteiz (Basque Country, Northern Iberian Peninsula) was able to establish a diachronic view of the evolution of the vegetal landscape, the plant economy and the forest management in this rural community between the 8th and 12th centuries ad, through the study of seeds, fruits, firewood, pollen, spores and non-pollen palynomorphs. The main results show the presence of an anthropogenic vegetal landscape, shaped by the economic activities of the inhabitants of the village, based on cereal crops, legumes and animal husbandry. Also new data are provided about forest management related to metallurgical activities.
