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.


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

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 …


Pliocene To Pleistocene Climate And Environmental History Of Lake El'gygytgyn, Far East Russian Arctic, Based On High-Resolution Inorganic Geochemistry Data, V Wennrich, P S.

The 3.6 Ma sediment record of Lake El'gygytgyn/NE Russia, Far East Russian Arctic, represents the longest continuous climate archive of the terrestrial Arctic. Its elemental composition as determined by X-ray fluorescence scanning exhibits significant changes since the mid-Pliocene caused by climate-driven variations in primary production, postdepositional diagenetic processes, and lake circulation as well as weathering processes in its catchment. During the mid- to late Pliocene, warmer and wetter climatic conditions are reflected by elevated Si / Ti ratios, indicating enhanced diatom production in the lake. Prior to 3.3 Ma, this signal is overprinted by intensified detrital input from the catchment, …


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 Jan 2013

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 …


The Significance And Vulnerability Of Australian Saltmarshes: Implications For Management In A Changing Climate, Neil Saintilan, Kerrylee Rogers Jan 2013

The Significance And Vulnerability Of Australian Saltmarshes: Implications For Management In A Changing Climate, Neil Saintilan, Kerrylee Rogers

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

We review the distribution, status and ecology of Australian saltmarshes and the mechanisms whereby enhanced atmospheric carbon dioxide and associated climate change have influenced and will influence the provision of ecosystem goods and services. Research in temperate and subtropical saltmarsh has demonstrated important trophic contributions to estuarine fisheries, mediated by the synchronised mass-spawning of crabs, which feed predominantly on the C-4 saltmarsh grass Sporobolus virginicus and microphytobenthos. Saltmarshes also provide unique feeding and habitat opportunities for several species of threatened microbats and birds, including migratory shorebirds. Saltmarshes increased in extent relative to mangrove in Australia in both tide- and wave-dominated …


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 …


Forest Fire Management, Climate Change, And The Risk Of Catastrophic Carbon Losses, David M. J. S Bowman, Brett P. Murphy, Mathias M. Boer, Ross A. Bradstock, Geoffrey J. Cary, Mark A. Cochrane, Rodderick J. Fensham, Meg A. Krawchuk, Owen F. Price, Richard J. Williams Jan 2013

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).


Lowland River Responses To Intraplate Tectonism And Climate Forcing Quantified With Luminescence And Cosmogenic 10be, J D. Jansen, G C. Nanson, T J. Cohen, T Fujioka, D Fabel, J R. Larsen, A T. Codilean, D M. Price, H H. Bowman, J.-H May, L A. Gliganic Jan 2013

Intraplate tectonism has produced large-scale folding that steers regional drainage systems, such as the 1600 km-long Cooper Ck, en route to Australia's continental depocentre at Lake Eyre. We apply cosmogenic 10Be exposure dating in bedrock, and luminescence dating in sediment, to quantify the erosional and depositional response of Cooper Ck where it incises the rising Innamincka Dome. The detachment of bedrock joint-blocks during extreme floods governs the minimum rate of incision (17.4±6.5 mm/ky) estimated using a numerical model of episodic erosion calibrated with our 10Be measurements. The last big-flood phase occurred no earlier than ∼112–121 ka. Upstream of the Innamincka …

The past 1500 years provide a valuable opportunity to study the response of the climate system to external forcings. However, the integration of paleoclimate proxies with climate modeling is critical to improving the understanding of climate dynamics. In this paper, a climate system model and proxy records are therefore used to study the role of natural and anthropogenic forcings in driving the global climate. The inverse and forward approaches to paleoclimate data–model comparison are applied, and sources of uncertainty are identified and discussed. In the first of two case studies, the climate model simulations are compared with multiproxy temperature reconstructions. …

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 …


Incorporating Estuaries As A Source Or Sink Of Sediment Within Assessments Of Coastline Risk And Adaptation To Climate Change, K Rogers, C D. Woodroffe Jan 2012

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 …

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.

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 …
