In this paper, we present palynological results from the Dahecun Core, Henan Province, China. Our pollen data indicate a warm and wet climate condition from 9200 to 4000 cal BP, which then switches to a cool and dry climatic condition during the Neolithic-Bronze Age transition (∼4000–3600 cal BP). We analyze 14C dates from archaeological sites to demonstrate four episodes of population increase and present vegetation dynamics, determined from available pollen data, to provide evidence for the synchronous shifts in vegetation and human population during the Neolithic. Our results indicate that the aridification in the early Bronze Age did not cause population collapse, highlighting the importance ...

Massive anthropogenic landscape transformation from the later Neolithic into the early Dynastic periods, especially in the Chinese Loess Plateau, increased sedimentation in the Yellow River requiring intensive investment in flood control features to protect an ever-growing population. As the Yellow River channel aggraded, channel gradients became increasingly steep, and avulsions occurred with greater frequency and consequence. Flooding reached an apogee in the first decades of the Common Era when a massive avulsion of the Yellow River ca. 14–17 CE caused the river to shift to the south and east of its...

Our 2011 fieldwork south of the Erlitou site in the Luoyang Basin indicates that an unconformity dating to ca. AD 1100 is roughly coincident with a major southward shift in the lower course of the Yellow River. In AD 1128, the governor of Kaifeng breached the dikes of the Yellow River to impede an advancing army, causing the Yellow River to flow south out to the Yellow Sea. We argue that the dike breach not only changed the fluvial dynamics of the Yellow River but also switched the rivers in the Luoyang Basin from an aggrading to an incising system. The resumption of sedimentation in the Luoyang Basin is roughly coincident with the next major shift of the Yellow River’s main course northward to the Bohai Sea in AD ...

Humans began to modify site-specific and local-level environments in the Early Holocene (~11,500–7000 BP). By the Mid-Holocene (~7000–5000 BP), the effects of humans on the environment become much larger and are witnessed at regional and tributary river basin scales. Land clearance and agriculture, as well as related land use, are dominant determinants of these changes. By the Late Neolithic to Early Bronze Age (~5000–3500 BP), population growth and intensification of agricultural production expanded the human footprint across the Yellow River region. By the Mid to Late Bronze Age (~3600–2200 BP), larger populations armed with better technology and propelled by more c...

When soils are especially clay-rich or moist the effectiveness of flotation decreases. As a result, paleoethnobotanical specimens are frequently mixed with heavy fraction remains and require a second stage of processing to isolate them from other artifacts. Although chemical flotation techniques provide one means of separating carbonized plant remains from heavy fractions, these methods can be expensive and frequently require the use of hazardous or toxic chemicals. This paper describes an alternative method of processing heavy fractions using sugar to increase the specific gravity of solution. We use one gallon of tap water 1nixed with 2.5 lb of sugar to form a solution with an approximate specific gravity of 1.11 g/ml. This solution is capable of floating charcoal and seeds, but is not dense enough to float bone, lithics, or fired clay. Using this technique, recovery rates between 96...

Jon Gibson excavated this unit and others in 1991 and argued that RW3 was constructed rapidly. We test the fast construction hypothesis by applying new methods (micromorphology, magnetic susceptibility, sequential loss-on-ignition) and by obtaining new radiocarbon dates. Before construction, the ground surface beneath RW3 was cleared and occupied. Preconstruction deposits are composed of anthropogenically enriched sediments. RW3 was constructed in layers of mixed heterogeneous natural and anthropogenically enriched sediments. The surfaces of these layers were used briefly during construction. The goal of the builders was to quickly raise the ridge to its full height. Magnetic susceptibility measurements and artifact density data show that the top of the constructed ridge is buried 10 to 30 cm below the modern surface. The construction of this section of RW3 was exceptionally rapid. The ridge was built after 3355–3210 cal BP and was under construction by at least 3450–2975 cal BP. Analysis of existing excavations offers great opportunity for pursuing vital research questions while having a limited effect on the integrity of archaeological deposits at Poverty Point.

An empirical global assessment of land use from 10,000 years before the present (yr B.P.) to 1850 CE reveals a planet largely transformed by hunter-gatherers, farmers, and pastoralists by 3000 years ago, considerably earlier than the dates in the land-use reconstructions commonly used by Earth scientists. Synthesis of knowledge contributed by more than 250 archaeologists highlighted gaps in archaeological expertise and data quality, which peaked for 2000 yr B.P. and in traditionally studied and wealthier regions. Archaeological reconstruction of global land-use history illuminates the deep roots of Earth’s transformation and challenges the emerging Anthropocene paradigm that large-scale anthropogenic global environmental change is mostly a recent phenomenon.

In this paper, we present palynological data from the early Bronze Age city of Dongzhao, Henan Province, China. Our data indicate that vegetation change and the development of early urban settlements are closely linked, with the advent of urban development significantly accelerating deforestation and altering the composition of local vegetation communities. The pollen record from Dongzhao provides new evidence to support the claim that urban expansion, coupled with a drying climate and the expansion of agriculture, dramatically reconfigured the landscapes of Bronze Age China.

This article explores archaeological evidence for crop cultivation, field-management practices and the use of farming implements at the Western Han (202 BC–AD 8) village of Sanyangzhuang in Henan Province, China. The authors analyse the implications of these practices for the newly developed smallholder mode of production. By combining diverse strands of evidence, this investigation provides new insights into the status of agricultural production in the Central Plains during the Western Han Dynasty.

The ability to map archaeological sites at a landscape scale provides researchers the possibility to reconstruct and assess the ways humans organized, constructed, and interacted with their surroundings. However, LiDAR can be impacted by a variety of modern development and land use practices. In this article, we confront these issues by presenting the first examination of high-resolution LiDAR-derived imagery from Central Kentucky, part of the larger heartland for late-Early and Middle Woodland-era (ca. 300 bc–ad 500) Adena-Hopewell societies. Our investigations demonstrate that multiple issues can arise when analyzing LiDAR imagery for monumental earthen architecture in this region. We outline an integrated strategy to rediscover and confirm the presence of earthen architecture made by Adena-Hopewell societies that incorporates aerial photographs, multi-instrument geophysical surveys, and geoarchaeological methods into the examination of LiDAR imagery. This methodology will be applicable in other global contexts where archaeologists are seeking to rediscover ancient forms of earthen architecture within heavily disturbed or developed landscapes.

Rapid climate change-induced collapse of hunter-gatherer societies in the lower Mississippi River valley between ca. 3300 and 2780 cal yr BP, 2018

In the lower Mississippi Valley (LMV) the Poverty Point culture defined this period of socio-political elaboration. However, following a significant period of climate change that led to exceptional flooding and a major reorganization of the course of the Mississippi River, this culture collapsed beginning ca. 3300–3200 cal yr BP and the LMV was abandoned for the subsequent 500 years. In this study, we use data from the Jaketown site in the Yazoo Basin of west-central Mississippi to refine the chronology of the climate event that caused the collapse of the Poverty Point culture. A large flood buried Poverty Point-era occupation deposits at Jaketown around 3310 cal yr BP. Lateral migration of the Mississippi River during flooding led to inundation of the Yazoo Basin and re-occupation of ancient river courses. A coarse sand stratu...

In the North China Plain, the historical record suggests a long tradition of irrigation, but archaeologists have found scant evidence of these technologies outside of urban areas. In 2012, 2015, and 2016, our excavations at the Anshang site, Neihuang County, Henan Province, China, revealed several archaeological features that we interpret as evidence of Late Shang dynasty (ca. 1200–1046 B.C.) canal construction in a nonurban context. By using a range of geological methods, including particle size, loss on ignition, magnetic susceptibility, and micromorphology, we suggest that these ancient canals and the subsequent construction phases found at Anshang not only influenced the development of local geomorphic conditions, but also were part of early dynastic attempts to restructure the natural landscape to facilitate agricultural productivity. These irrigation canals found at Anshang may be representative of broader trends of human-environmental interactions in the North China Plain.

More recently, scholars have begun to challenge these works, rejecting the notion of collapse altogether in favor of focusing on concepts such as resilience and transformation. Driven by these developments, archaeologists have turned their attention to what occurs in the aftermath of sociopolitical decline, attempting to identify factors that contribute to the regeneration, transformation, or reorganization of complex sociopolitical institutions. Subsequent research has provided important data shedding light on political environments that were once characterized as “dark ages.” In that time, general theoretical approaches have transformed as well, and recent frameworks reconsider collapse and reorganization not as unrelated or sequential phenomena but as integral components in a cyclical understanding of the evolution of complex societies. The most recent of these approaches incorporates the tenets of Resilience Theory, as developed by environmental scientists.
In March 2013, an international conference held at Southern Illinois University in Carbondale brought together scholars with diverse theoretical perspectives to present and synthesize new data and approaches to understanding the collapse and reorganization of complex societies. No restrictions were imposed regarding chronological periods, geographical regions or material specialties, resulting in a wide-ranging potential for comparative analysis. This publication is the outcome of that meeting. It is not organized merely as a collection of diverse case studies, but rather a collaborative effort incorporating various data sets to evaluate and expand on theoretical approaches to this important subject. The works contained within this volume are organized into five sections: the first sets the stage with introductory papers by the editor and distinguished contributor, Joseph Tainter; the second contains works by distinguished scholars approaching collapse and reorganization from new theoretical perspectives; the third presents critical archaeological analyses of the effectiveness of Resilience Theory as a heuristic tool for modeling these phenomena; the fourth section presents long-term adaptive strategies employed by prehistoric societies to cope with stresses and avoid collapse; the final section highlights new research on post-decline contexts in a variety of temporal and geographic ranges and relates these data to the more comprehensive works on the subject.

This deposit was associated with the site’s Early Woodland component. Recent fieldwork at Jaketown also encountered the same tetrahedron deposit and identified an additional and distinct pit feature filled with the objects. In this article, we present the results of analyses that examine the production, composition, chronology, and function of these enigmatic baked-clay artifacts. Following a hiatus associated with massive flooding in the Mississippi Valley ca. 3200–2850 cal B.P., Jaketown was re-occupied by people who shared ceramic affinities with groups to the south and to the east and, who like many contemporaries, used BCOs as a part of their cooking technology. The tetrahedron deposit represents one of the earliest dated Tchula contexts at ca. 2600 cal B.P., and was used over a short time for a social purpose that brought populations together for food consumption as a means of encouraging cooperation.
