Risk and low-density dispersed urbanism
Settlements operate across a wide range of densities and do so for every socio- economic mode of life from those based on hunter-gatherer economies to those which are based on industrial production. Human beings also live across a range of residential densities from very high to very low. Why they do so is a function of many factors, especially differing socio-cultural ways of managing interaction and communication and the associated social and p…
Re-imagining Sydney’s freshwater wetlands through historical ecology
Australian conservation targets commonly focus on preserving a vaguely defined ecological baseline, often conceptualised as a pre-European, ‘natural’ state. For instance, environmental legislation protects ‘Endangered Ecological Communities’ (EECs), which purportedly represent remnants of naturally occurring biota. However, EECs are often classified without long-term data, making it unclear as to whether the community being protected is indeed ‘n…
Letting the plants speak
The Botany Wetlands are the contemporary remnant of a formerly extensive coastal freshwater wetland in the inner-urban suburbs of Sydney (Australia). This site supports a range of ecosystem services, including human physical and mental health benefits, filtration of stormwater runoff from a highly urban and industrial catchment, and accommodation space for floodwater. The wetlands also provide habitat to migratory water birds and act as a connect…
Paul Bishop and the longue durée of human–environmental relations in SE Asia
Paul Bishop’s contribution to the earth sciences is profound. His work on large spatial and temporal scale landscape evolution is well known, but he also (and coevally) directed his attention to the complexities of human–environmental interactions, with all their site-based and short-term cultural idiosyncrasies. His focus on mainland SE Asia, and Thailand in particular, reflects a long-standing fascination in and affection for the region and its…
Re-examining climate-driven Malthusian collapse in Kashmir
Patterns of aeolian deposition in subtropical Australia through the last glacial and deglacial periods
Debate about the nature of climate and the magnitude of ecological change across Australia during the last glacial maximum (LGM; 26.5–19 ka) persists despite considerable research into the late Pleistocene. This is partly due to a lack of detailed paleoenvironmental records and reliable chronological frameworks. Geochemical and geochronological analyses of a 60 ka sedimentary record from Brown Lake, subtropical Queensland, are presented and consi…
Tracing the Networks of Past Societies in Palaeoenvironmental Research
Historical societies reshaped their environment in various ways; by clearing forest, cultivating crops, mining, and modifying waterways. Evidence of these activities persists in palaeoenvironmental archives, which represent comprehensive histories of human activity in a landscape. Analysis of settlement networks across landscapes is another common approach to investigating how past societies operated, but these analyses rarely incorporate palaeoe…
Multi-stage Holocene evolution of the River Murray Estuary, South Australia
The River Murray Estuary, South Australia exhibits a morphology typical of a wave-dominated estuary and comprises two large, shallow central basin lakes – Lakes Alexandrina and Albert. Contested interpretations of the estuary’s limnological history and uncertainty surrounding the sustainability of current basin water usage practice warrant a robust investigation into how the system has evolved. Here we combine lithostratigraphic, geochemical and …
The environmental context of a city in decline
Radiocarbon Dating of a Speleothem Record of Paleoclimate for Angkor, Cambodia
We report the chronological construction for the top portion of a speleothem, PC1, from southern Cambodia with the aim of reconstructing a continuous high-resolution climate record covering the fluorescence and decline of the medieval Khmer kingdom and its capital at Angkor (~9th–15th centuries AD). Earlier attempts to date PC1 by the standard U-Th method proved unsuccessful. We have therefore dated this speleothem using radiocarbon. Fifty carbon…
Claiming the hydraulic network of Angkor with Viṣṇu
Prior to the investigations in 2004–2005 of the West Mebon and subsequent analysis of archaeological material in 2015 it was presumed that the Mebon was built in the mid-11th century and consecrated only once. New data indicates a possible re-use of the water shrine and a refurbishment and reconsecration in the early 12th century, at which time a large sculpture of Viṣṇu was installed. Understanding the context of the West Mebon is vital to under…

Unearthing an Atlantean myth in Angkor
Climate as a contributing factor in the demise of Angkor, Cambodia
The “hydraulic city” of Angkor, the capitol of the Khmer Empire in Cambodia, experienced decades-long drought interspersed with intense monsoons in the fourteenth and fifteenth centuries that, in combination with other factors, contributed to its eventual demise. The climatic evidence comes from a seven-and-a-half century robust hydroclimate reconstruction from tropical southern Vietnamese tree rings. The Angkor droughts were of a duration and se…
The Mekong at Climatic Crossroads
The wetlands of the lower Mekong River Basin are ecologically and socioeconomically significant, but they are threatened by predicted climatic change. The likely response of wetland ecosystems to altered flooding regimes and surface-water chemistry is unknown in detail and difficult to model. One way of exploring the impact of climate change on wetland ecosystems is to utilize proxy environmental data that reveal patterns of change over geologica…
Sediment
It has been claimed that Tonle Sap Lake is rapidly filling with sediment as a result of increasing sediment yields from the catchment. Infilling of the lake basin would have serious implications for the magnitude of flooding in central Cambodia and the Mekong Delta region and threaten the lake's unique ecosystem. In this article, we synthesize the results of radiocarbon dating of sediment cores and hydrodynamic modeling results to provide an empi…
The water management network of Angkor, Cambodia
Meticulous survey of the banks, channels and reservoirs at Angkor shows them to have been part of a large scale water management network instigated in the ninth century AD. Water collected from the hills was stored and could have been distributed for a wide variety of purposes including flood control, agriculture and ritual while a system of overflows and bypasses carried surplus water away to the lake, the Tonle Sap, to the south. The network ha…
Holocene palaeoenvironments and change at Three-Quarter Mile Lake, Silver Plains Station, Cape York Peninsula, Australia
Pollen and diatom analyses of organic sediments from Three-Quarter Mile Lake, a perched lake on Cape York Peninsula, north Queensland, indicate that significant changes in vegetation and hydrology occurred during the Holocene. Early Holocene grass-dominated landscapes were replaced in mid-Holocene times by increasingly woody vegetation comprising tropical heathlands, savanna and rainforest. Early-Holocene lake levels fluctuated widely. From mid-H…
Vegetation and land-use at Angkor, Cambodia
Investigating the use of land during the medieval period at the celebrated ceremonial area of Angkor, the authors took a soil column over 2.5m deep from the inner moat of the Bakong temple. The dated pollen sequence showed that the temple moat was dug in the eighth century AD and that the agriculture of the immediate area subsequently flourished. In the tenth century AD agriculture declined and the moat became choked with water-plants. It was at …
Microfossil evidence of land-use intensification in north Thailand
A 3.5 ka record of paleoenvironments and human occupation at Angkor Borei, Mekong Delta, southern Cambodia
Microfossil and sedimentological data from a 3.1 m core extracted from a reservoir ( baray ) at the ancient Cambodian settlement of Angkor Borei in the Mekong Delta have provided a continuous record of sedimentation and paleoenvironments dating from about 2000 cal yr B.C. Palynological data indicate that for much of the cal. 1st and 2nd millennia B.C. mangroves dominated the regional vegetation, while extensively and regularly burnt grasslands do…
