Identifying and explaining changes in the prehistoric material and social world is one of the greatest research interests in archaeology, palaeoclimate and environmental science. In the last two decades or so, a considerable number of studies have made significant contributions to the associated disciplines in eastern Asian archaeology. However, due to the more specialised scientific approaches and the rapid accumulation of new excavation materials, it becomes increasingly difficult for scholars to examine and correlate research outputs from different areas and achieve a holistic picture of the past. Using eastern Asian archaeology as an example, this Special Issue aims to break down the disciplinary boundaries and present the current research debate on how to correlate different climate, environmental and social changes and explain human past. One of the fundamental issues is the lack of adequate chronological resolution to order various archaeological events. To tackle this, a large number of radiocarbon dates, primarily derived from short- lived materials, are provided in the Special Issue. A great variety of changes in local environment, agricultural practice, animal husbandry, technologies, migration, demography and social organisations are revealed in the following papers but there are two profound drivers to all of these changes. One is the broad climate change since the start of the Holocene and the other is the communication between the West and the East. [ABSTRACT FROM AUTHOR]

A comprehensive and integrative view of East Asian monsoon evolution during the Holocene is still under debate, and additional high-resolution proxy records from climatically sensitive locations are requisite to solve this complex issue. In this paper, we present three well-dated mud/peat cores from a paleo-pingo depression in the Sanjiang Plain, a climatically sensitive region to monsoon variation, to reveal the paleoenvironmental history of the wetland and discuss the regional impacts from monsoon evolution. A paleolake developed in the study area before 5.5 ka BP, and a peatland initiated thereafter consequent upon the gradual shrinking of the paleolake. This transition lasted until 4.5 ka BP, when the paleolake changed entirely to a wetland. Considering the prevalent monsoon climate in the Sanjiang Plain, we suggest that the lake-to-wetland transition from 5.5 to 4.5 ka BP indicates a rapid decline of the East Asian summer monsoon in addition to autogenic basin infilling processes. Such a remarkable monsoon weakening event has been documented across northern China, and we associate this with ocean–atmosphere interactions throughout low-latitude regions. [ABSTRACT FROM AUTHOR]

For well over a century, scholars from across the social and biological sciences have been trying to understand the origins and spread of agriculture. This debate is often intertwined with discussions of climate change and human environmental impact. Over the past decade, this debate has spread into Central Eurasia, from western China to Ukraine and southern Russia to Turkmenistan, a part of the world often thought to have been largely dominated by pastoralists. A growing interest in the prehistory of Central Eurasia has spurred a new chapter in the origins of agriculture debate; archaeobotanical research is showing how important farming practices in this region were in regard to the spread of crops across the Old World. While early people living in Central Eurasia played an influential role in shaping human history, there is still limited understanding of the trajectories of social evolution among these populations. In March 2015, 30 leading scholars from around the globe came together in Berlin, Germany, to discuss the introduction and intensification of agriculture in Central Eurasia and adjacent regions. At the German Archaeological Institute in Berlin (Deutsches Archäologisches Institut, DAI), these scholars presented novel data on topics covering East, South, and Central Asia, spanning a wide realm of methodological approaches. The present special edition volume deals with a selection of the papers given at this conference, and it marks a significant step toward recognizing the contribution of Central Eurasian populations in the spread and development of agricultural systems over the course of the Holocene.
