North Macedonia is a crucial region for understanding the spread of agriculture into the Mediterranean and Central Europe. To date, however, the area has been subject to relatively limited archaeological research. Here, the authors present use-wear and archaeobotanical analyses on material from two Neolithic sites, Govrelevo and Vrbjanska Čuka, to investigate practices that were previously unstudied in this part of the Balkans, such as sowing, cultivation and harvesting techniques. The results suggest the presence of permanent crop fields located in wetlands, with autumn and spring sowing, and harvesting using curved sickles. The study illuminates early agricultural practices in North Macedonia and adds to our knowledge of the spread of the Neolithic package across Europe.

The dating and routes by which humans colonised South America continue to be debated. Recent research in Uruguay has yielded new Palaeoindian lithic finds from the southern shores of the coastal Merín Lagoon. The author's analysis of a group of Fell points—comparable to other regional examples—shows that this widespread artefact was produced using locally available materials and that they were repeatedly resharpened and repaired until no longer functional. The finds from the Merín Lagoon permit consideration of changing sea levels and their influence on colonisation routes, resource exploitation and archaeological preservation. The Atlantic coastline may have been one possible route of entry for early colonisers of South America.

Throughout the Late Pleistocene and Early Holocene, humans adapted to significant climate and environmental change. One key region for investigating these adaptive strategies is Island Southeast Asia, where fluctuating sea levels led to dramatic changes in coastlines, vegetation and fauna. The authors present new data from the re-excavation of Pilanduk Cave on Palawan Island, Philippines. The results corroborate the results of earlier excavations that identified Pleistocene occupation of the site. Pilanduk shows evidence for specialised deer hunting and freshwater mollusc consumption during the Last Glacial Maximum. The results add to the evidence for the shifting foraging behaviours of modern humans occupying variable tropical environments across Island Southeast Asia.

The remarkable archaeological record of Neolithic Orkney has ensured that these islands play a prominent role in narratives of European late prehistory, yet knowledge of the subsequent Bronze Age is comparatively poor. The Bronze Age settlement and cemetery at the Links of Noltland, on the island of Westray, offers new evidence, including aDNA, that points to a substantial population replacement between the Late Neolithic and Bronze Age. Focusing on funerary practice, the authors argue for interconnecting identities centred on household and community, patrilocality and inheritance. The findings prompt a reconsideration of the Orcadian Bronze Age, with wider implications for population movement and the uptake of cultural innovations more widely across prehistoric north-western Europe.

Established chronologies indicate a long-term ‘Hoabinhian’ hunter-gatherer occupation of Mainland Southeast Asia during the Terminal Pleistocene to Mid-Holocene (45 000–3000 years ago). Here, the authors re-examine the ‘Hoabinhian’ sequence from north-west Thailand using new radiocarbon and luminescence data from Spirit Cave, Steep Cliff Cave and Banyan Valley Cave. The results indicate that hunter-gatherers exploited this ecologically diverse region throughout the Terminal Pleistocene and the Pleistocene–Holocene transition, and into the period during which agricultural lifeways emerged in the Holocene. Hunter-gatherers did not abandon this highland region of Thailand during periods of environmental and socioeconomic change.

Climate change is affecting archaeological sites and landscapes around the world. Increased rainfall, more frequent extreme weather events, higher temperatures and rising seas not only create new risks but also exacerbate existing vulnerabilities and threats. Building on an earlier Antiquity article that explored climate change and arctic archaeology (Hollesen et al. 2018), this special section provides a global perspective on the impact of climate change on archaeological sites and landscapes and how archaeologists and cultural heritage managers are responding. This article introduces the following three contributions, outlining their main findings to provide an overview of the various challenges around the world, and highlighting current gaps in knowledge and future research opportunities.

The Intergovernmental Panel on Climate Change has documented wide-ranging changes to the world's coasts and oceans, with significant further change predicted. Impacts on coastal and underwater heritage sites, however, remain relatively poorly understood. The authors draw on 30 years of research into coastal and underwater archaeological sites to highlight some of the interrelated processes of deterioration and damage. Emphasising the need for closer collaboration between, on one hand, archaeologists and cultural resource managers and, on the other, climate and marine scientists, this article also discusses research from other disciplines that informs understanding of the complexity of the interaction of natural and anthropogenic processes and their impacts on cultural heritage.

Thirty years after the discovery of an Early Neolithic timber hall at Balbridie in Scotland was reported in Antiquity, new analysis of the site's archaeobotanical assemblage, featuring 20 000 cereal grains preserved when the building burnt down in the early fourth millennium BC, provides new insights into early farming practices. The results of stable isotope analyses of cereals from Balbridie, alongside archaeobotanical and stable isotope results from three other sites, indicate that while cereals were successfully cultivated in well-established plots without manuring at Balbridie, a variety of manuring strategies was implemented at the other sites. These differences reinforce the picture of variability in cultivation practices across Neolithic North-west Europe.

The inhabitants of the vast Chalcolithic Trypillia sites of Eastern Europe required highly organised strategies to meet subsistence needs. Here, the authors use isotopic analyses of faunal remains from Maidanetske, Ukraine, to identify intensive and extensive grazing practices. The former demanded intra-community negotiation to ensure access to high-quality pastures for valuable animals such as dairy cows, suggesting that pasture may have also served socially integrative functions. The simultaneous use of extensive pasturing strategies for cattle placed on different pastureland suggests that landscapes were partitioned, with access determined by cooperation or competition. Maidanetske's dual pasturing system reflects the importance of spatially organised practices in maintaining social structure.

Common assumptions about the ephemeral archaeological signature of pastoralist settlements have limited the application of geophysical techniques in the investigation of past herding societies. Here, the authors present a geophysical survey of Luxmanda, Tanzania, the largest-known settlement documented for the Pastoral Neolithic era in eastern Africa (c. 5000–1200 BP). The results demonstrate the value and potential of fluxgate gradiometry for the identification of magnetic anomalies relating to archaeological features, at a category of site where evidence for habitation was long thought to be undetectable. The study provides comparative data to enable archaeologists to identify loci for future investigations of mobile populations in eastern Africa and elsewhere.

Stable isotope analyses demonstrate that C4 plants played an important dietary role in Eurasian prehistory. Uncertainty remains, however, about when and how crops were integrated into the diet of Central Asian populations. Here, the authors present δ13C and δ15N stable isotope analysis of human and animal bone collagen from Kyrgyzstan, revealing C4 plant—likely broomcorn millet—consumption in the third millennium BC. Combining this evidence with AMS radiocarbon dating and animal collagen peptide fingerprinting demonstrates that broomcorn millet was consumed by humans and animals during the earliest episodes of the westward spread of this crop plant. The results contribute to debates about the timing and means by which domesticated millets were dispersed across Eurasia.

The hunter-fisher-gatherers of fourth- to third-millennium BC north-eastern Europe shared many characteristics traditionally associated with Neolithic and Chalcolithic agricultural societies. Here, the authors examine north-eastern European hunter-fisher-gatherer exchange networks, focusing on the Russian Karelian lithic industry. The geographically limited, large-scale production of Russian Karelian artefacts for export testifies to the specialised production of lithic material culture that was exchanged over 1000km from the production workshops. Functioning both as everyday tools and objects of social and ritual engagement, and perhaps even constituting a means of long-distance communication, the Russian Karelian industry finds parallels with the exchange systems of contemporaneous European agricultural populations.

Evidence for both basket weaving and salt production is often elusive in the prehistoric archaeological record. An assemblage of Middle–Late Chalcolithic pottery from Provadia-Solnitsata in Bulgaria provides insight into these two different technologies and the relationship between them. The authors analyse sherds from vessels used in large-scale salt production, the bases of which bear the impression of woven mats. This analysis reveals the possible raw materials used in mat weaving at Provadia-Solnitsata and allows interpretation of the role of these mats in salt production at the site. The results illustrate how it is possible to see the ‘invisible’ material culture of prehistoric south-eastern Europe and its importance for production and consumption.

Wetland archaeological sites offer excellent but vulnerable preservation conditions. This article presents examples of threats to such sites that may be enhanced, or diminished, by climate change, discusses methods for predicting and quantifying impacts, and examines what heritage managers can do to mitigate their effects. The consequences of climate change for wetland archaeological sites are likely to be severe and widespread but hard to predict and with significant local variation. At the same time, wetlands are increasingly acknowledged for their ability to sequester carbon and to mitigate climate change, prompting an increased focus on their protection that may also benefit wetland archaeology.
