This study presents a series of new radiocarbon dates and the first stable carbon and nitrogen isotope measurements of C3 cereal grains from Roman Iron Age (1–400 AD) archaeobotanical assemblages in Lithuania, southeastern Baltic region. These data are complemented by stable isotope measurements of faunal remains to assess local environmental conditions and evaluate human impact on the landscape through agricultural practices. The δ15N and δ13C values indicate that agriculture during this period relied heavily on intensive manuring and cultivation in open, well-irrigated landscapes. The results also reveal diverse cultivation strategies across sites, with isotopic differences between rye and barley suggesting the possible use of an infield–outfield cultivation system. Radiocarbon dates indicate that these agricultural innovations may have started as early as the 1st to mid-2nd century AD with the introduction of rye, however the evidence points to a gradual and uneven adoption rather than a rapid uniform shift.

A newly discovered Neolithic site at Al-Khashbah KHS-A (Oman) reveals local adaptations to climate change in the Holocene. Results from radiocarbon dating show repeated occupations over 1000 years and key artefacts indicate coastal connections. KHS-A served as a short-term camp, enhancing our understanding of Neolithic lifeways in Arabia.

Despite being almost 4000m above sea level, cereal crops have been grown in the Ngari Prefecture on the Tibetan Plateau for thousands of years. Where and when domestic crop species adapted to high-altitude growing conditions is a matter of ongoing debate. Here, the authors present a new radiocarbon date from the Gepa serul cemetery, providing the earliest evidence of naked six-rowed barley in Tibet (c. 3500 BP). Evaluating the available evidence for barley cultivation and interregional connections in central Asia at this time, two hypotheses are considered—a generational advance with farmers migrating up river valleys or rapid, long-distance trade through mountain corridors.

Written accounts suggest there were major changes in agricultural practices in Anatolia as the region switched between Roman, Byzantine, Arab and Turkic control, yet archaeological evidence of these changes is offered only on a site-by-site basis. This article presents the first synthesis of archaeobotanical, palynological and zooarchaeological evidence for changes in plant and animal husbandry in Anatolia through the first and second millennia AD. Available data indicate a minimal role of climate change in agricultural shifts but offer evidence for substantial changes towards short-term-return agricultural strategies in response to declining personal security, changing patterns of military provisioning and distinct taxation regimes.

El objetivo del presente trabajo es analizar el registro de Chenopodium recuperado en el poblado pukara El Carmen 1, sector centro-occidental del valle de Santa María, Tucumán (ca. 1200-1450 dC). Para ello se trabajó con una muestra de 310 macrorrestos provenientes de las excavaciones realizadas en el poblado alto (recinto 13, sector VI). El predominio y alta densidad de granos de Chenopodium quinoa Willd. y Chenopodium cf. quinoa Willd. con evidencias de procesamiento en la estructura de combustión, podría corresponder a prácticas de tostado y/o hidratación en el marco de preparaciones culinarias. La ubicación del recinto 13 en el espacio de mayor jerarquía dentro del sitio y su posición centralizada dentro del sector, sugieren la importancia de la quinoa para los habitantes del poblado y llevan a pensar en su rol en el marco de encuentros, ceremonias o eventos rituales en los que el procesamiento y la elaboración de comidas y/o bebidas adquieren importancia.

En este trabajo presentamos la primera evidencia de cultivo de Triticeae (trigo y/o cebada) en una parcela arqueológica del sitio Pueblo Guayascate 1, emplazado en la actual provincia de Córdoba, centro de Argentina. La presencia de especies euroasiáticas tras la instauración del orden colonial ibérico en el actual territorio argentino ha sido referenciada por la documentación escrita de los siglos dieciséis y diecisiete y corroborada por los análisis de restos arqueológicos macro y microbotánicos. Guayascate fue parte de una encomienda —y luego de una merced de tierras— que le fue otorgada a los españoles a finales del siglo dieciséis. Esto implicó no sólo la presencia de mano de obra de los antiguos habitantes del lugar, sino también la ocupación de sus tierras, lo cual es signo de contacto y co-existencia entre españoles y nativos. Los análisis de microrrestos botánicos silicios al sedimento de una parcela en momentos de contacto y ocupación, evidencian el cultivo de trigo y/o cebada en asociación con maíz. Este hallazgo nos permite arriesgar algunas conjeturas sobre la producción y el consumo de alimentos de estos grupos, como también avanzar en el conocimiento sobre los cambios y continuidades en la cultura alimenticia acaecidos tras la instauración del sistema colonial.

Institutional food is renowned for being monotonous and unappetising, yet the accuracy of these prescribed diets is difficult to verify archaeologically. Desiccated plant remains from beneath the floorboards at Hyde Park Barracks in Sydney offer a rare insight into the culture of food at the Female Immigration Depot (1848–1887) and the Destitute Asylum (1862–1886). Here, the author reveals the wide range of unofficial plant foods accessed by inhabitants at these two institutions—representing resources sourced from across the British Empire—and the sometimes-illicit nature of their consumption, highlighting the importance of incorporating archaeological evidence into discussions of institutional life.

The emergence of early cities required new agricultural practices and archaeobotanical crop-processing models have been used to investigate the social and economic organisation of urban ‘consumer’ and non-urban ‘producer’ sites. Archaeobotanical work on the Indus Valley has previously identified various interpretations of labour and subsistence practices. Here, the authors analyse a large archaeobotanical assemblage from Harappa, Pakistan (3700–1300 BC), questioning some of the assumptions of traditional crop-processing models. The ubiquity of small weed seeds, typically removed during the early stages of crop processing, is argued to result from dung burning. This additional taphonomic consideration adds nuance to the understanding of Harappa's labour organisation and food supply with implications for crop-processing models in other contexts.

China was a centre for early plant domestication, millets in the north and rice in the south, with both crops then spreading widely. The Laoguantai Culture (c. 8000–7000 BP) of the middle Yellow River region encompasses a crucial stage in the transition from hunting and gathering to farming, yet its subsistence basis is poorly understood. The authors present archaeobotanical data from the site of Beiliu indicating that farmers exploited a variety of wild and cultivated plants. The predominance of broomcorn millet accords with other Neolithic cultures in northern China but the presence of rice—some of the earliest directly dated examples—opens questions about the integration of rice cultivation into local subsistence strategies.

New research in the microregion of Musti (El Krib) in N Tunisia in 2019–2023 has revealed unpublished 2nd–3rd-century AD funerary monuments featuring rich iconography, including a female figure beside the altar and two pigs. These items and other published epigraphic and anepigraphic monuments from the fertile microregion stand out from other tombstones in Roman Africa. Both the type of monument and its relief decoration distinguish these objects. A rare holistic approach, combining historical, epigraphic and iconographic analyses with the results of archaeobotanical and archaeozoological research, will enhance our understanding of the history and agriculture of the Musti microregion and this part of Proconsular Africa during the early Roman Empire.

Famars (ancient Fanum Martis) is situated in northern Gaul, in the south of the Nervian territory. Large-scale investigations undertaken over the last ten years have enabled in-depth analyses of archaeobotanical, archaeozoological and ceramic data, alongside other artefacts. These analyses have demonstrated the town's management of raw materials yielded by its territory, as well as the processing and redistribution of the finished products on a local and regional scale, and across the whole of northern Gaul. Such settlements were part of the Empire's system for supplying troops and inhabitants with food and materials of all kinds. Although data from perishable or otherwise ephemeral materials are limited, ceramics can act as proxy evidence of the production and distribution of other products. This paper provides an overview of these recent discoveries and places them in the broader context of Roman-period supply networks.

The analysis of coprolites provides direct evidence of resources consumed and may be paired with ethnographic data to elucidate the dietary and medicinal use of plants in archaeological communities. This article combines and contrasts the macroscopic analysis and DNA metabarcoding of 10 coprolites from Bonneville Estates Rockshelter, Nevada, USA. While the results from both methods confirm previous understandings of subsistence practices at the site, minimal overlap in identified taxa suggests that each accesses different components of the consumed material. The two methods should therefore be seen as complementary and employed together, where possible.

A dearth of published archaeobotanical data from the Late Bronze Age of western Anatolia limits our understanding of agricultural production in this key area. Recent excavations at Çine-Tepecik provide insights into farming and the political economy in the kingdom of Mira within the lands of Arzawa. Archaeobotanical assemblages indicate that farming was structured to meet both domestic and institutional consumption; the former utilising a wide range of crop species while the latter focused on cereals. Plant remains provide further evidence for a ‘hybrid’ suite of farming practices across western Anatolia and contribute to debate around the spread of broomcorn millet cultivation.

This project focuses on the subsistence strategies of Early Neolithic communities that inhabited the upland region of South Bohemia. Its results reveal a distinctive trajectory for this peripheral area that was colonised significantly later, brought incoming farmers into close contact with hunter-gatherers and made them adapt their conservative farming practices.

Regional variation in the historic development of agricultural societies in South-west Asia is increasingly apparent. Recent investigations at the wetland site of Balıklı (c. 8300–7900 BC) provide new insights into the initial processes of sedentism in Central Anatolia and the interaction of early communities within local and larger-scale networks. Located near major obsidian sources, excellent architectural preservation and faunal and botanical records at Balıklı suggest cultural connections to the upper Middle Euphrates region, yet inhabitants of the site do not appear to have participated in the wider South-west Asian obsidian-exchange networks and largely relied on wild resources.

The nature and timing of the transition to farming north of the Linearbandkeramik zone in Europe is the subject of much debate, but our understanding of this fundamental shift in lifeways is hampered by the low resolution of available data. This article presents new multi-proxy evidence from Swifterbant (4240–4050 BC), in the Dutch wetlands, for morphologically domestic cattle with two different dietary regimes. The authors argue that the results indicate early animal management, alongside arable farming and the continuance of foraging practices, prompting the reconsideration away from broad statements about the Neolithic north of the Linearbandkeramik zone towards more local trajectories.

Broomcorn millet and foxtail millet were first cultivated in Neolithic China then the process spread west across Asia during the Bronze Age. But the distinctive ceramic, and later bronze, vessels utilised in East Asian cuisines for boiling and steaming grains did not move west alongside these crops. Here, the authors use measurements of 3876 charred millet grains to evaluate regional variations and implications for food preparation. In contrast to wheat grains, which became smaller as their cultivation moved east, millet grains became larger as they spread from northern China into Inner Asia and Tibet. This indicates the decoupling of millets from associated cooking techniques as they reached geographical and cultural areas.
