Soils are key to ecosystems and human societies, and their critical importance requires a better understanding of how they evolve through time. However, identifying the role of natural climate change versus human activity (e.g. agriculture) on soil evolution is difficult. Here we show that for most of the past 12,300 years soil erosion and development were impacted differently by natural climate variability, as recorded by sediments deposited in Lake Dojran (Macedonia/Greece): short-lived ( < 1,000 years) climatic shifts had no effect on soil development but impacted soil erosion. This decoupling disappeared between 3,500 and 3,100 years ago, when the sedimentary record suggests an unprecedented erosion event associated with the development of agriculture in the region. Our results show unambiguously how differently soils evolved under natural climate variability (between 12,300 and 3,500 years ago) and later in response to intensifying human impact. The transition from natural to anthropogenic landscape started just before, or at, the onset of the Greek 'Dark Ages' (~3,200 cal yr BP). This could represent the earliest recorded sign of a negative feedback between civilization and environmental impact, where the development of agriculture impacted soil resources, which in turn resulted in a slowdown of civilization expansion.


A 6-Month Randomised Controlled Trial Investigating Effects Of Mediterranean-Style Diet And Fish Oil Supplementation On Dietary Behaviour Change, Mental And Cardiometabolic Health And Health-Related Quality Of Life In Adults With Depression (Helfimed): Study Protocol, Dorota M.

Background: Modern diets, characterised by excess consumption of processed foods, are accompanied by an epidemic of chronic diseases. Cardiovascular disease and depression carry a large burden of disease and often occur together. Poor dietary patterns have been identified as an independent risk factor for depression while healthy diets with minimally processed food are protective. Traditional Mediterranean diets have been shown to reduce risk of cardiovascular disease; however there is a need for clinical trials in people with depression. This paper reports the study protocol of a Mediterranean-style diet intervention conducted in adults with self-reported depression. Methods/design: HELFIMED is a ...


Distributed Leadership: Building Capacity For Interdisciplinary Climate Change Teaching At Four Universities, Aidan Davison, Paul Brown, Emma Pharo, Kristin Warr, Helen Mcgregor, Sarah Terkes, Davina Boyd, Pamela Abuodha Jan 2014

Distributed Leadership: Building Capacity For Interdisciplinary Climate Change Teaching At Four Universities, Aidan Davison, Paul Brown, Emma Pharo, Kristin Warr, Helen Mcgregor, Sarah Terkes, Davina Boyd, Pamela Abuodha

Faculty of Science, Medicine and Health - Papers: part A

Purpose - Interdisciplinary approaches to climate change teaching are well justified and arise from the complexity of climate change challenges and the integrated problem-solving responses they demand. These approaches require academic teachers to collaborate across disciplines. Yet, the fragmentation typical of universities impedes collaborative teaching practice. This paper aims to report on the outcomes of a distributed leadership project in four Australian universities aimed at enhancing interdisciplinary climate change teaching. Design/methodology/approach - Communities of teaching practice were established at four Australian universities with participants drawn from a wide range of disciplines. The establishment and operation of these communities relied on ...


Dominating The Antarctic Environment: Bryophytes In A Time Of Change, Jessica Bramley-Alves, Diana H. King, Sharon A. Robinson, Rebecca E. Miller Jan 2014

Dominating The Antarctic Environment: Bryophytes In A Time Of Change, Jessica Bramley-Alves, Diana H. King, Sharon A. Robinson, Rebecca E. Miller

Faculty of Science, Medicine and Health - Papers: part A

Polar ecosystems, and particularly Antarctica, are one of the few environs in which bryophytes dominate the flora. Their success in these regions is due to bryophytes’ ability to withstand an array of harsh conditions through their poikilohydric lifestyle. However, the unique conditions that allow bryophytes to proliferate over other forms of vegetation also create considerable limitations to growth and photosynthetic activity. High latitude areas are already experiencing some of the most pronounced and rapid climatic change, especially in the Arctic, the Sub-Antarctic Islands and Maritime Antarctica, and these are predicted to continue over the next century. This climatic change is ...


Rates Of Shoreline Change Along The Coast Of Bangladesh, Md. Golam Mahabub Sarwar, Colin D. Woodroffe May 2013

Rates Of Shoreline Change Along The Coast Of Bangladesh, Md. Golam Mahabub Sarwar, Colin D. Woodroffe

Faculty of Science, Medicine and Health - Papers: part A

Bangladesh, at the confluence of the sediment-laden Ganges and Brahmaputra Rivers, supports an enormous and rapidly growing population (>140 million in 2011), across low-lying alluvial and delta plains that have accumulated over the past few thousand years. It has been identified as one of the most vulnerable places in the world to the impacts of climate change and sea-level rise. Although abundant sediment supply has resulted in accretion on some parts of the coast of Bangladesh, others are experiencing rapid erosion. We report a systematic assessment of rates of shoreline change over a 20-year period from 1989 to 2009, using ...

Coastal Evolution On Volcanic Oceanic Islands: A Complex Interplay Between Volcanism, Erosion, Sedimentation, Sea-Level Change And Biogenic Production, Ricardo S. Ramalho, Rui Quartau, Alan S. Trenhaile, Neil C. Mitchell, Colin D. Woodroffe, Sergio P. Avila Jan 2013

Coastal Evolution On Volcanic Oceanic Islands: A Complex Interplay Between Volcanism, Erosion, Sedimentation, Sea-Level Change And Biogenic Production, Ricardo S. Ramalho, Rui Quartau, Alan S. Trenhaile, Neil C. Mitchell, Colin D. Woodroffe, Sergio P. Avila

Faculty of Science, Medicine and Health - Papers: part A

The growth and decay of oceanic hotspot volcanoes are intrinsically related to a competition between volcanic construction and erosive destruction, and coastlines are at the forefront of such confrontation. In this paper, we review the several mechanisms that interact and contribute to the development of coastlines on oceanic island volcanoes, and how these processes evolve throughout the islands' lifetime. Volcanic constructional processes dominate during the emergent island and subaerial shield-building stages. During the emergent island stage, surtseyan activity prevails and hydroclastic and pyroclastic structures form; these structures are generally ephemeral because they can be rapidly obliterated by marine erosion. With ...


Application Of Thresholds Of Potential Concern And Limits Of Acceptable Change In The Condition Assessment Of A Significant Wetland, Kerrylee Rogers, Neil Saintilan, Matthew J. Colloff, Li Wen Jan 2013

Application Of Thresholds Of Potential Concern And Limits Of Acceptable Change In The Condition Assessment Of A Significant Wetland, Kerrylee Rogers, Neil Saintilan, Matthew J. Colloff, Li Wen

Faculty of Science, Medicine and Health - Papers: part A

We propose a framework in which thresholds of potential concern (TPCs) and limits of acceptable change (LACs) are used in concert in the assessment of wetland condition and vulnerability and apply the framework in a case study. The lower Murrumbidgee River floodplain (the 'Lowbidgee') is one of the most ecologically important wetlands in Australia and the focus of intense management intervention by State and Federal government agencies. We used a targeted management stakeholder workshop to identify key values that contribute to the ecological significance of the Lowbidgee floodplain, and identified LACs that, if crossed, would signify the loss of significance ...

Approaches to management of fireprone forests are undergoing rapid change, driven by recognition that technological attempts to subdue fire at large scales (fire suppression) are ecologically and economically unsustainable. However, our current framework for intervention excludes the full scope of the fire management problem within the broader context of fire−vegetation−climate interactions. Climate change may already be causing unprecedented fire activity, and even if current fires are within the historical range of variability, models predict that current fire management problems will be compounded by more frequent extreme fire-conducive weather conditions (eg Fried et al. 2004).

Debate concerning the environmental impact of human arrival in Australia has continued for more than a century. Here we review the evidence for human impact and the mechanisms by which humans may have affected the environment of tropical Australia. We limit our review to tropical Australia because, over three decades ago, it was proposed that the imposition of an anthropogenic fire regime upon human occupation of the Australian continent may have resulted in profound changes in regional vegetation and climate across this region. We conclude that ecological processes and vegetation-fire-climate-human feedbacks do exist that could have driven a significant shift ...


Accuracy Of Micrometeorological Techniques For Detecting A Change In Methane Emissions From A Herd Of Cattle, Johannes Laubach, Mei Bai, Cesar S. Pinares-Patino, Frances A. Phillips, Travis A. Naylor, German Molano, Edgar A. Cardenas Rocha, David W. T Griffith Jan 2013

Accuracy Of Micrometeorological Techniques For Detecting A Change In Methane Emissions From A Herd Of Cattle, Johannes Laubach, Mei Bai, Cesar S. Pinares-Patino, Frances A. Phillips, Travis A. Naylor, German Molano, Edgar A. Cardenas Rocha, David W. T Griffith

Faculty of Science, Medicine and Health - Papers: part A

Micrometeorological techniques are effective in measuring methane (CH4) emission rates at the herd scale, but their suitability as verification tools for emissions mitigation depends on the uncertainty with which they can detect a treatment difference. An experiment was designed to test for a range of techniques whether they could detect a change in weekly mean emission rate from a herd of cattle, in response to a controlled change in feed supply. The cattle were kept in an enclosure and fed pasture baleage, of amounts increasing from one week to the next. Methane emission rates were measured at the herd scale ...


Tuvalu, Sovereignty And Climate Change: Considering Fenua, The Archipelago And Emigration, Elaine Stratford, Carol Farbotko, Heather Lazrus Jan 2013

Tuvalu, Sovereignty And Climate Change: Considering Fenua, The Archipelago And Emigration, Elaine Stratford, Carol Farbotko, Heather Lazrus

Faculty of Science, Medicine and Health - Papers: part A

Tuvalu is a Pacific atoll nation-state that has come to stand for predicaments implicating climate change, forced emigration and resettlement, and loss of territory and sovereignty. Legal and policy remedies seek to address such challenges by radically reframing how sovereignty is conceived. Drawing on literary and legal theory, we seek to extend such work in the terms of cultural geography and anthropology by considering how the archipelago and cultural practices known as fenua could be deployed as symbolic and material resources emphasizing mobility and connection, in contrast to normative ideas of sovereignty, whose orientation to territory imperils atoll states. Our ...


Changing Role Of Local Institutions To Enable Individual And Collective Actions For Adapting To Climate Change, Popular Gentle, Rik Thwaites, Digby Race, Kim Alexander Jan 2013

Changing Role Of Local Institutions To Enable Individual And Collective Actions For Adapting To Climate Change, Popular Gentle, Rik Thwaites, Digby Race, Kim Alexander

Faculty of Science, Medicine and Health - Papers: part A

Studies and practices on commons have demonstrated that local institutions can develop institutional arrangements to manage resources such as forests and water and can ensure benefit sharing mechanisms in a sustainable and equitable way. The characters, functions and roles of local institutions required to manage commons are well studied and translated in practice. Few researchers have reported on the role of local institutions in adaptation to climate change and variability with little known about key characters and functions reqUired. This article is based on a case study research in the mountains of Nepal following a mixed method approach including in-depth ...

Faculty of Science, Medicine and Health - Papers: part A

We present the first intercalibration of dry-air column-averaged mole fractions of methane (XCH4) retrieved from solar Fourier transform infrared (FTIR) measurements of the Network for the Detection of Atmospheric Composition Change (NDACC) in the mid-infrared (MIR) versus near-infrared (NIR) soundings from the Total Carbon Column Observing Network (TCCON). The study uses multi-annual quasi-coincident MIR and NIR measurements from the stations Garmisch, Germany (47.48° N, 11.06° E, 743 m a.s.l.), and Wollongong, Australia (34.41° S, 150.88° E, 30 m a.s.l.). Direct comparison of the retrieved MIR and NIR XCH4 time series for Garmisch ...

Zones Of Friction, Zones Of Traction: The Connected Household In Climate Change And Sustainability Policy, L M. Head, C Farbotko, C Gibson, N Gill, Gordon R. Waitt

Faculty of Science, Medicine and Health - Papers: part A

Households are increasingly addressed as a focus of environmental policy, with varying degrees of success in achieving more sustainable outcomes at the domestic level. Part of the problem is black boxing, in which the inherent complexity of households tends to be taken for granted. Here we draw on cultural environmental research to put forward a more sophisticated conceptualisation - the connected household approach. The connected household framework uses the themes of governance, materiality and practice to illustrate and explain the ways everyday life, and the internal politics of households, are connected to wider systems of provision and socioeconomic networks. We introduce ...

The parties to the Montreal Protocol are informed by three panels of experts. One of these is the Environmental Effects Assessment Panel (EEAP), which deals with two focal issues. The first focus is the effects of increased UV radiation on human health, animals, plants, biogeochemistry, air quality, and materials. The second focus is on interactions between UV radiation and global climate change and how these may affect humans and the environment. When considering the effects of climate change, it has become clear that processes resulting in changes in stratospheric ozone are more complex than believed previously. As a result of ...


Climate Change And Displacement: Multidisciplinary Perspectives - Book Review, Carol Farbotko Jan 2012

Climate Change And Displacement: Multidisciplinary Perspectives - Book Review, Carol Farbotko

Faculty of Science, Medicine and Health - Papers: part A

In the small but growing field of research into climate change and migration, there is much debate about terms. Attempts to definitively count the numbers or pinpoint the characteristics of 'climate refugees' are being discarded in favour of more nuanced descriptors, such as climate-induced migration, that are better attuned to the agency and complexity of populations on the move in a warming world. The choice of the word 'displacement' in the title of this book, therefore, reveals much about its editor's intent.


Global Change And Fire Regimes In Australia, Geoffrey J. Cary, Ross A. Bradstock, A Malcolm Gill, Richard J. Williams Jan 2012

Global Change And Fire Regimes In Australia, Geoffrey J. Cary, Ross A. Bradstock, A Malcolm Gill, Richard J. Williams

Faculty of Science, Medicine and Health - Papers: part A

Global change can be defined strictly in terms of changes in atmospheric composition, climate and land use (Walker and Steffen 1996), although broader definitions also include human population, economy and urbanisation (Steffen et al. 2004). In Australia, global change significantly affects the drivers of fire activity and there is potential for considerable changes in fire regimes. It is widely accepted that carbon dioxide (C02) concentration in the atmosphere is steadily increasing (see Steele et al. 2007), as is nitrous oxide (Forster et al. 2007). Atmospheric methane concentration has also risen significantly, but is now relatively constant (Beer et al. 2006 ...

Incorporating Estuaries As A Source Or Sink Of Sediment Within Assessments Of Coastline Risk And Adaptation To Climate Change, K Rogers, C D. Woodroffe

Faculty of Science, Medicine and Health - Papers: part A

Complex coastal landforms exhibit variable behaviour in response to sea-level rise. A proposed modelling framework that integrates shoreline changes associated with longterm recession, short-term variability and sea-level rise advocates that coastal risk assessment be undertaken within the context of a geomorphologically-based modelling framework whereby a coastline is subdivided into coastal compartments or cells, thereby recognising the sedimentary links between compartments. For example, the Narrabeen coastline includes bounding headland compartments, a bay compartment and an estuary compartment; and the behaviour of the coastline varies according to the response of each of these compartments to variable climatic and oceanic conditions. This approach ...


Coastal Saltmarsh Vulnerability To Climate Change In Se Australia, Neil Saintilan, Kerrylee Rogers Jan 2009

Coastal Saltmarsh Vulnerability To Climate Change In Se Australia, Neil Saintilan, Kerrylee Rogers

Faculty of Science, Medicine and Health - Papers: part A

Coastal saltmarsh has been listed as an Endangered Ecological Community in New South Wales. Recent research has highlighted the importance of coastal saltmarsh as a source of nutrition for fish, a nocturnal feeding habitat for microbats, and a roosting habitat for several species of migratory shorebirds. Since European colonisation, coastal saltmarsh has been reclaimed for agricultural, residential and industrial use, and the past five decades has seen a consistent replacement of saltmarsh by mangrove throughout SE Australia. Analysis of data from the network of Surface Elevation Tables in NSW and Victoria has demonstrated a link between the replacement of saltmarsh ...

The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have instrumental data (the last 50 years). We consider their consequences for the biosphere, and show how the latest numerical models project changes into the future, taking into account human actions in the form of the release of greenhouse gases and chlorofluorocarbons into the atmosphere. In doing so, we provide an essential Southern Hemisphere ...
