In recent years, ethnoarchaeological studies focusing on herbivore faecal remains within the soils, especially those from goat, sheep and cattle, have shown the importance of their study for identifying socio-economic activities. Thus, an accurate microstratigraphic examination of these deposits can provide us new insights into past land use, site formation processes, activity areas and intensity of use of space, mobility, domestic use of fuel, manuring, and foddering strategies. Mountain landscapes represent a relatively new terrain of investigation for geo-ethnoarchaeology. In this paper, we present a pilot project featuring an applied inter-disciplinary methodology that includes micromorphology, bulk stable isotope analysis (δ13C and δ15N), phytolith, pollen and non-pollen palynomorphs (NPPs) analyses. These were carried out on samples from three high-mountain (up to 1400 m a.s.l.) pastoral sites located at Monti Sibillini, in the Italian central Apennines. Results show that the presence of anthropic organic-rich deposits, even when poorly preserved, (1) allows for an accurate description of herbivore dung internal characteristics, (2) establishes precise microstratigraphy of anthropogenic deposits and husbandry practices related to intensity of use of space, and (3) gives accurate information about former vegetation and landscape use in the local area. Based on this exploratory ethnoarchaeological approach, we discuss the potential of micro-analyses of archaeological decayed or burnt livestock dung in a small set of samples collected during a initial survey for obtaining insights into the environment and husbandry practices from dung and goat stabling floors in a high-mountain context.

Many societal and environmental changes occurred between the 2nd millennium BC and the middle of the 2nd millennium AD in western Africa. Key amongst these were changes in land use due to the spread and development of agricultural strategies, which may have had widespread consequences for the climate, hydrology, biodiversity, and ecosystem services of the region. Quantification of these land-use influences and potential feedbacks between human and natural systems is controversial, however, in part because the archaeological and historical record is highly fragmented in time and space. To improve our understanding of how humans contributed to the development of African landscapes, we developed an atlas of land-use practices in western Africa for nine time-windows over the period 1800 BC–AD 1500. The maps are based on a broad synthesis of archaeological, archaeobotanical, archaeozoological, historical, linguistic, genetic, and ethnographic data, and present land use in 12 basic categories. The main differences between categories is the relative reliance on, and variety of, domesticated plant and animal species utilized, and the energy invested in cultivating or keeping them. The maps highlight the irregular and frequently non-linear trajectory of land-use change in the prehistory of western Africa. Representing an original attempt to produce rigorous spatial synthesis from diverse sources, the atlas will be useful for a range of studies of human–environment interactions in the past, and highlight major spatial and temporal gaps in data that may guide future field studies.

The Kel Tadrart Tuareg, desert pastoralists from the Tadrart Acacus massif in Libya, were the subject of an ethnoarchaeological research carried out between 2003 and 2011. By means of a multi-pronged approach, a variety of topics were explored, ranging from the Kel Tadrart interactions with natural resources and the settlement pattern, to the layout of campsites and the processes of sites' abandonment. The study of the Kel Tadrart adaptation to an arid environment and patchy resources, along with the recording of material evidence, holds direct relevance to archaeologists, anthropologists, and stakeholders interested in sustainable dryland pastoralism.

The excavation at Takarkori rock shelter is part of a long-term study of Holocene cultural dynamics in southwest Libya begun in the early 1990s. With a rich Holocene occupation, the area is one of the key spots for reconstruction of human occupation of the last 10,000 years. In this region, similar to the case in the rest of the Sahara, most of the data come from surface investigations at open-air sites, while excavated caves and rock shelters provide just a few. Although less exposed than open-air sites, Holocene archaeological deposits in Saharan caves and rock shelters are characterized by a fairly dynamic nature. Loose sediments, coupled with variability of human occupations and magnitude of natural agents, determine multiple alterations to the archaeological deposits in sheltered sites. In this paper, we present the nature and meaning of the archaeological deposits at Takarkori rock shelter, where a relatively large area has been recently excavated, showing a stratigraphic sequence extending from c. 9,000 to 4,200 BP, unevenly represented by several occupation pulses. In order to sharpen understanding of the development of human occupation at this site, specific procedures for the study and recording of the archaeological deposit have been developed, along with a program of extensive radiocarbon dating. Data from the Takarkori sequence ultimately will be integrated with available published stratigraphies from the Acacus Mountains, with the aim of reviewing the results from past excavations.

In the prehistoric green Sahara of Holocene North Africa-in contrast to the Neolithic of Europe and Eurasia-a reliance on cattle, sheep and goats emerged as a stable and widespread way of life, long before the first evidence for domesticated plants or settled village farming communities. The remarkable rock art found widely across the region depicts cattle herding among early Saharan pastoral groups, and includes rare scenes of milking; however, these images can rarely be reliably dated. Although the faunal evidence provides further confirmation of the importance of cattle and other domesticates, the scarcity of cattle bones makes it impossible to ascertain herd structures via kill-off patterns, thereby precluding interpretations of whether dairying was practiced. Because pottery production begins early in northern Africa the potential exists to investigate diet and subsistence practices using molecular and isotopic analyses of absorbed food residues. This approach has been successful in determining the chronology of dairying beginning in the 'Fertile Crescent' of the Near East and its spread across Europe. Here we report the first unequivocal chemical evidence, based on the ?13C and ?13C values of the major alkanoic acids of milk fat, for the adoption of dairying practices by prehistoric Saharan African people in the fifth millennium bc. Interpretations are supported by a new database of modern ruminant animal fats collected from Africa. These findings confirm the importance of 'lifetime products', such as milk, in early Saharan pastoralism, and provide an evolutionary context for the emergence of lactase persistence in Africa.
