South Hangzhou Bay in eastern China occupies an important position in tracing the origins and dispersal of rice and rice cultures in ancient China. Existing literature suggests that early coastal rice domestication emerged ca.8000-7400 years ago in the Kuahuqiao area, at the apex of the Bay, but no solid evidence implies a simultaneous domestication at any other places in this region. This paper presents

Trace metals in archived lichen and fungi samples, dating back over 158 years were measured to ascertain their potential to record temporal shifts in atmospheric source inputs; starting from the onset of industrial activity in Australia, to the present. Lichen (Cladonia n = 85; Usnea n = 47) and fungi (Trametes n = 40) samples from the greater Sydney and Melbourne areas were analysed for their total

Human impact on western Mediterranean mountains is gaining more attention, as they harbour a rich plant diversity threatened by global change. This paper presents an analysis of two pollen records from both sides of Sierra Nevada, the prime plant-diversity centre of the Mediterranean, spanning the last 5400 years. The analysis sought to answer the following key questions: When did natural systems transform

The permanence of glaciers worldwide is uncertain due to increasing temperatures and decreasing precipitation. Glaciers are essential as strategic water reservoirs. They pose natural risks, constitute economic resources, and contribute to the rise in sea levels. Identifying places that remain relatively protected against these changes, and that could act as climate change refugia (CCR), is essential

Palynological studies and archaeological discoveries suggest repeated extensive prehistoric copper mining in the Eisenerz Alps (Styria, Austria). In an attempt to reconstruct the specific temporal evolution of copper (Cu) mining activity in this area from the Bronze Age to the medieval period, this article presents records of elemental variations, trace elemental enrichments of Cu, nickel (Ni), zinc

High mountain lakes are valuable sentinels of global change because they are sensitive to environmental stress and integrate changes in the atmosphere and their catchment areas. This study tested the hypothesis that local and regional anthropogenic stressors have affected productivity, sedimentation, and organic carbon burial in two tropical high mountain lakes in central Mexico. We studied changes

The comparison of matched historical and repeat photograph pairs provides an important tool to assess historical trends in vegetation and landscape change. An analysis of repeat photographs is invaluable for ground-truthing and augmenting an understanding of trajectories of vegetation change derived from other methods such as aerial photographs, remote sensing and models. In this article, we comment

Examining vegetation change over decadal to centennial timescales by comparing paired sets of historic and contemporary field photographs is a tried and tested approach, used recently in many ecological studies in southern Africa. This approach, however, fails to consider the different forcing factors contributing to vegetation and landscape change over historical time periods. This Viewpoint article

Mexico is a biologically megadiverse country, but its biodiversity is endangered due to high deforestation rates. Impacts of land-use/cover-change and climate change are unevenly distributed, which hinders the execution of conservation practices. Consequently, an adequate spatial conservation prioritization is crucial to minimize the negative impacts on biodiversity. Global and national efforts to

Industrial-era warming and aridification have underlined the importance of past climate reconstructions in contextualizing present-day anomalies from a long-term perspective. While the issue of climate change is global, studies have long stressed the vulnerability of the Mediterranean basin, especially with regard to its islands with likely acute environmental and socioeconomic impacts. This study

Large-amplitude meanders may form in low-energy rivers despite generally limited mobility in theses systems. Exceptionally large meanders which even extend beyond the valley sides have developed in the Overijsselse Vecht river (the Netherlands) between ca. 1400 CE (Common Era) and the early 1900s, when channelization occurred. Previous studies have attributed the enhanced lateral dynamics of this river

Landscape Evolution Models (LEMs) simulate the movement of water and sediment over the landscape. Although much progress has been made in the development of LEMs, few have been tested in rivers subject to anthropogenic impacts that produce high energy flows, transporting large amounts of sediment and causing significant geomorphic changes. As such, it remains uncertain if LEMs are useful and stable

Mitigating human contributions to climate change is a highly debated topic, as it becomes evident that many nations do not adhere to optional reductions in global emission. Substantial research is taking place into negative carbon technologies that actively reduce the amount of atmospheric carbon dioxide (CO2) via greenhouse gas removal (GGR). Various GGR methods have been proposed, from reforestation

This study assesses the evolution of 104 inhabited and 82 resort islands across the Maldives between 2004-2006 and 2014-2016 and investigates the contribution of human drivers. Using multi-date satellite imagery, we show that 59.1 % of these islands expanded as a result of human intervention, including mainly land reclamation (often associated with harbor development) and the construction of engineering

Pandemics have accelerated in frequency in recent decades, with COVID-19 the latest to join the list. Emerging in late 2019 in Wuhan, China, the virus has spread quickly through the world, affecting billions of people through quarantine, and at the same time claiming more than 800,000 lives worldwide. While early reflections from the academic community have tended to target the microbiology, medicine

The Southern Ocean is warming faster than the average global ocean and is particularly vulnerable to ocean acidification due to its low temperatures and moderate alkalinity. Coccolithophores are the most productive calcifying phytoplankton and an important component of Southern Ocean ecosystems. Laboratory observations on the most abundant coccolithophore, Emiliania huxleyi, suggest that this species

Payments for ecosystem services (PES) programs have been implemented worldwide to balance human needs and ecosystem conservation. However, the effects of PES programs on economic activities and the associated effects on wildlife remain unclear. China’s Grain-to-Green program (GTGP) that aims to convert cropland to forest or grassland represents one of the largest PES programs in the world. We combine

Physical heterogeneity is a strong driver of ecosystem function in rivers, but it is not clear whether this relationship persists in “Anthropocene” rivers: those affected by pronounced and persistent anthropogenic stressors. Such stressors can result in regime shifts of rivers, altering not only ecosystem structure and function, but also their heterogeneity. This study examines the heterogeneity of

From mobile hunter-gatherers to a series of state societies, Mediterranean climate regions (MED) around the world have been critical areas for human and biological evolution for millennia. Comprised of five regions on six continents, the MED are important today for human settlement, global food production, transportation, industry, and tourism, but these regions are also extremely vulnerable to projected

Ancient soils contain geochemical signatures of human land use, making them usable as a “golden spike,” or globally synchronous marker, to identify traces of the early “Anthropocene.” This article examines the sedimentary record in northern China to determine when, and under what cultural circumstances, did ancient pollution appear in buried soils and sediments. Using methods of Inductively Coupled

Human activities can greatly affect the chemical and biological composition of High Arctic lakes that otherwise receive only sparse inputs from their watersheds and airsheds. This paper reports a study of three High Arctic waterbodies in which wastewater from an airport was released over the span of several decades. Using sediment cores from these waterbodies, we reconstructed the history of wastewater

With increasing costs of floods across the globe, interest has grown in using managed retreat strategies, such as home buyouts, for flood mitigation. For years, national-level estimates of the benefits of flood mitigation investments in the United States have been estimated as being on the order of 4:1 (USD) or more recently 6:1 (USD), according to the Federal Emergency management Agency and others

The concept of legacy sediments, introduced in the early 2010s, is increasingly common to refer to sediment produced in watersheds within a limited period by anthropogenic disturbances. Primarily applied for cases in the USA, legacy sediment is a key concept to characterize the health of river corridors and design relevant restoration schemes. Surprisingly, examples of legacy sediments in European

Human societies rely on rules to function, curbing the interests of individuals in favor of the interests of the population. A review of recent progress in biology and digital sciences suggests that such strategies might be universal: many living and technological systems favor the interests of the population to the detriment of individuals, at all scales. They behave in a suboptimal manner, restraining

Islands contribute enormously to global biodiversity, but their species and ecosystems are highly threatened and often confined to small patches of remaining native vegetation. Islands are thus ideal microcosms to study the local dimensions of global change. While human activities have drastically transformed most islands, the extent to which societal and environmental conditions shape differences

Dendrogeomorphic analyses provide long and continuous chronologies of mass movements that are useful for the detection of trends related to climate change. Socio-environmental changes can, however, induce non-stationarities. This study addresses the following questions: (1) How does the evolution of forest cover induce non-stationarities in tree-ring based reconstructions of snow avalanche activity

Why are we still educating college and university students through a Holocene lens? How can we expect young people to engage with the transformative challenges required to meet the targets of the Paris Agreement when climate change education is organized in a narrow and linear fashion? Climate change courses and teaching modules largely emphasize scientific literacy through a focus on physical processes

Both global warming and human impacts are inimical to the maintenance of biodiversity across the planet. Although there is some consensus regarding the probable responses of biodiversity changes under different global change scenarios, the factors controlling biodiversity on regional scales are unclear. Using surveys of lake-bed surface sediments and an analysis of diatoms from six lake cores across

Managing invasive species is currently a key issue for preserving biodiversity. The role of managers of transport infrastructure is essential because roads, railways and rivers are known to facilitate the spread of invasive species. This is the case for Fallopia spp. (knotweeds) in particular, which is a highly invasive species in Europe. Previous studies have indicated strong motivation among environmental

The characteristics of hydroclimatic risk in the 21st Century are rapidly changing. Increases in extreme weather events and population densities alter exposure to floods and droughts. Water infrastructure is unable to keep pace and deterministic models can mislead. Yet, predominant strategies for managing risk continue to follow historical precedent, striving to tame nature's outbursts and mitigate

To test the extent to which sediments accumulated in sewers may serve as high-resolution archives of urban evolution, this study examined a sedimentary succession deposited in a decantation tank of the combined sewer network of Orléans (France). The focus was on a 1.43 m sediment core drilled after 10 months of operation since the last cleaning. Sediments were stratigraphically organised into three

Litter is a significant environmental issue, threatening all ocean environments including the deep sea, where little is known about the extent of the threat. This study collected underwater videos on shelf-indenting canyons (the Gioia and Petrace Canyon) and adjacent sectors to characterize benthic litter and its distribution patterns. A high density of litter was present in the canyon thalwegs (up

Many large cities worldwide are built on natural and engineered geological materials that are highly susceptible to liquefaction and associated ground failure in earthquakes. Constitutive equations describing relationships between sediment geotechnical characteristics, seismological parameters, and liquefaction susceptibility of natural and engineered sediments are well established. What is less understood

Biological and cultural diversity are integrally linked, yet understanding how culture impacts biological extinction is limited. The orchid richness of Southwest China’s Sichuan Province is the second highest in China, but price speculation and overharvest have resulted in significant recent orchid population collapses. Due to the importance of Cymbidium orchids to Han Chinese traditional culture,

Industrial lead (Pb) emissions have changed oceanic Pb concentrations and isotopic compositions significantly over the last century. Asian industrial emissions are currently the dominant Pb sources in the northwest and central Pacific Ocean. This study investigated major Pb sources in the northeast Pacific Ocean (inland, coastal, and open ocean), where no comprehensive data exist currently. We measured

The impact of human activities on sediment yield is poorly constrained in the northeastern United States, as in other northern hemisphere forested landscapes previously occupied by Pleistocene ice sheets. This study examines changes in sedimentation in Little Kennebago Lake (LKL), Maine, in relation to extreme hydrologic events and land-use change. Historical records indicate minimal disturbance before

This paper reviews how human impacts produced a marked shift from natural processes in the potential input of terrestrial mammals to the fossil record, both in composition of the mammal taxa and in processes controlling their preservation. These issues are key considerations in predicting the future fossil record of the modern vertebrate fauna and determining if there will be a resultant “Anthropocene”

Mercury (Hg) is a toxic metal that threatens the health of aquatic ecosystems and fish consumers. Its natural cycle has been deeply perturbed by Anthropogenic Hg emissions have deeply perturbed its natural cycle, especially since the start of the Industrial Revolution circa 1850 CE. Anthropogenic Hg emissions from North America and Europe have decreased by a factor of two in the last decades following

Spatial and temporal variability in precipitation, land use, and river channels introduce uncertainty in flood estimates and pose challenges for floodplain management and mitigation. Yet, standard deterministic methods for quantifying flood hazards and evaluating risk assume stationarity in a nonstationary world and fail to account for uncertainties as they translate to flood hazards. A need exists

Industrial wastes and by-products are increasingly (re-)used as filling material in constructions. To enhance awareness among the geological community of the growing and widespread occurrence of deposits that contain these “novel anthropogenic materials”, this paper reviews three volumetrically important materials: (1) ash remaining from the incineration of household waste (Municipal Solid Waste Incineration

This paper presents an overview of the scientific evidence providing insights into long term ecosystem and social dynamics across the northern Tanzania and southern Kenya borderlands. The data sources covered a range from palaeoenvironmental records and archaeological information to remote sensing and social science studies that examined human-environmental interactions and land use land cover changes

In expanding informal neighborhoods of cities in sub-Saharan Africa, sustainable management of storm and wastewater drainage is fundamental to improving living conditions. Planners debate the optimal combination between "green" or natural infrastructure, traditional "grey" infrastructure, and "blue" infrastructure, which mimics natural solutions using artificial materials. Many advocate for small-scale

Urbanization affects runoff processes and sediment transport, but the magnitude of the impacts remains poorly understood. Different spatial patterns of pervious and impervious surfaces influence flow and sediment connectivity between hillslopes and stream networks. Following years of research on the peri-urbanizing Ribeira dos Covões catchment in Portugal, this study uses laboratory rainfall simulation

Previous research exploring the environmental justice implications of urban flood hazards has produced contrasting results due to the different dasymetric mapping techniques used, the various spatial scales of the analyses, and the specific geographical context of the individual study cities, particularly as it relates to the presence of coastal water-based amenities. To better understand if vulnerable

Stormwater ponds are ubiquitous features of developed landscapes of the eastern United States. Their design specifically controls the pace of water runoff from impervious cover of surrounding watersheds. Ponds accumulate organic matter that typically decomposes anaerobically in bottom sediments, and thus may be significant sources of greenhouse gases to the atmosphere (e.g., carbon dioxide (CO2), methane

How people perceive the risks of climatic hazards is currently a major research thrust in the field of risk perception. In the wake of recent flood disasters in the United States (US) and globally, more researchers are investigating social vulnerabilities as well as the role of cognition in explaining risk perceptions. This study analyzed how people in the US perceive the risk (i.e., likelihood and

Mineral dust aerosols are a key component of the Earth system and a growing public health concern under climate change, as levels of dustiness increase. The Great Plains in the USA is particularly vulnerable to dust episodes, but land-atmosphere interactions contributing to large-scale dust transport are poorly constrained. This study compiled one of the longest quantitative, spatially-comprehensive

Forests bear the historical legacies of human activities over thousands of years, including agriculture, trade, disease and resource extraction. Many of these activities may represent indices of the proposed geological epoch of the Anthropocene. Modifications to soil, topography and vegetation evidence anthropogenic influences. Yet studies of vegetation change throughout the humid tropics tend to occlude

Although human interventions have influenced many coastal areas around the world, research has rarely assessed the environmental impacts of these anthropogenic perturbations. To understand the dominant coastal interventions in countries with tropical areas, this study established a baseline along the continental Caribbean coast of Colombia (approximates 1700 km), based on 29 types of human interventions

Greenhouse gas accounting for agricultural systems consider methane and nitrous oxide emissions, carbon emissions from liming and urea use, as well as carbon stock changes, but it ignores gross flows of bio-based energy and carbon. This study compiled data for Canada’s agri-food system over the 2010-13 period, from food supply and disposition to crop processing, animal production, and crop/pasture

War has an immediate and obvious effect on people and communities, but its impacts on local ecology can be more subtle. This paper shows how one military encounter in the Second World War has left a clear legacy in the northern forests of Norway, trackable more than seventy years later. We used annual growth rings of ∼180 pine and ∼30 birch trees as witnesses of the deployment of the German battleship

In the Great Lakes basin of North America, snow plays a critical role in the regional hydroclimate, where snow ablation events can serve both as a resource and a hazard. The frequency and magnitude of an ablation event is governed by the availability of meteorological conditions to ablate snow, and the physical presence of snow to be ablated. While the meteorological conditions leading to ablation

Cities are urged to promote green infrastructures to reduce their global environmental impacts, while simultaneously adapting to the global climatic variability that such impacts generate. Human Niche Construction theory, however, predicts evolutionary pressures acting over social groups that, this paper contends, tend to favor gray over green infrastructure. This conflict is due to competitive advantages

This paper addresses a topic highlighted in recent arguments by Amazonian scholars: the extent to which forms of forest management in prehistory influenced the past and present composition of terra firme and riverine forests. New information on palm phytolith characteristics enabled phytolith analysis on soils sampled from underneath forests in western and central Amazon. We evaluated whether three

This study analyzed with dendrochronology 177 Heldreich’s pines growing on the Pollino Massif in southern Italy for understanding climatic and human impacts on old trees. Most of the large-diameter trees currently living became established in the late Medieval to Renaissance periods under a snowy wet climate and low anthropic influence. Millennium-old (i.e., > 900 years of age) trees in remote sites

The centrality of culture for achieving environmental sustainability has long been underscored by philosophers, psychologists, and social scientists concerned about the environment. However, to date few studies have detected an empirical relationship between cultural dimensions and actual environmental impacts on Earth (e.g., the Ecological Footprint, EF). This study examined the hypothesis that an

This study presents glacio-archaeological evidence from the Miyar basin, Lahaul Himalaya, that points towards the former presence of a well settled agricultural society, within a glacier end moraine complex. Three high altitude villages (Tharang, Phundang and Patam, now in ruins) with elaborate irrigation networks thrived within the end moraine complex of Tharang glacier at 3700 m a.s.l. Evidence exists
