Effect of moisture on fine dust emission from tillage operations on agricultural soils
The aim of this paper is to determine the influence of soil moisture on the particulate matter (PM) emission of soils subjected to mechanical disturbance, particularly tillage. Measurements in Europe indicate that emission of dust by tillage
operations is many times higher than by natural wind erosion. The AA. used a wind tunnel as a cross-flow gravitational separator to investigate the relation between soil type, soil moisture and fine dust emission. Twelve soils of different texture were
investigated with regard to their water content. The results show the importance of the vertical soil moisture profile on the PM emission of soils.
MRICES : A new model for emission mitigation strategy assessment and its application
on several strategies for global emission reduction, including the egalitarianism strategy, the UNDP strategy and the Copenhagen Accord. Using 1990 as a baseline for historical emission levels, the egalitarian strategy argues that developed countries should
implement urgent emission reductions, whereas developing countries are allowed relatively higher future emission quotas. Based on analysis on mitigation strategies, it is recognized that the common but differentiated responsibility principle must be insisted
Recent advances in our understanding of dust source emission processes
This review provides a critical overview of recent studies of aeolian processes from within or on dust sources, and focuses on studies dealing with retrieval of dust emission data, quantification of the contribution and variability of dust emissions
of important components of the dust cycle derived through use of remote sensing data. However, for strategies aimed at inclusion of dust emission schemes at a scale relevant to climate models, additional research is needed to increase the quantification
Soil organic carbon enrichment of dust emissions : magnitude, mechanisms and its implications for the carbon cycle
This study examines the SOC content and enrichment of dust emissions measured using Big Spring Number Eight (BSNE) wind-vane samplers across 5 land types in the rangelands of western Queensland, Australia. The results show that sandy soils and finer
particulate quartz-rich soils are more efficient at SOC emission and have larger SOC dust enrichment than clay-rich aggregated soils. The AA. hypothesize that stronger inter-particle bonds and the low grain density of the aggregated clay soil explain its
reduced capacity to release SOC during saltation, relative to the particulate sandy soils. They also show that size-selective sorting of SOC during transport may lead to further enrichment of SOC dust emissions. These preliminary results provide impetus
Effect of type and quality of two contrasting plant residues on CO2 emission potential of Ultisol soil : Implications for indirect influence of temperature and moisture
An incubation experiment was conducted to investigate CO2 emission potentials of Ultisol soils under residues of peanut (green manure) and rice (rice straw) and moisture regimes 60% (W1) and 120% (W2) of water holding capacity at different
or incorporation of plant residues are in fact major factors which control the CO2 emission potential of soils by converting soils from CO2–C sources to sinks. On the other hand, other abiotic factors like temperature and moisture are indirect regulator of CO2
production and emission by influencing decomposition of these incorporated organic inputs.
External supply of dust regulates dust emissions from sand deserts
Here, the AA. show that an external dust supply is also an important dust contributor to the sand desert, and that dust emission from the sand desert will occur if an external dust supply is available and diminish if the external supply is cut off
. Their results relate the dust emission from sand deserts to an external dust supply resulting from disturbed processes or changed hydrological processes caused by climate changes or human activities, and also suggest that the dust emission rate of natural sand
The role of forest ecosystems and wood in controlling the absorption and emission of carbon dioxide
Forests play a quadruple role in the processes of global change : 1) as a cause, a source of the emission of greenhouse gases (GHC), predominantly in result of deforestation; 2) as a victim of global climatic change, due to the increased sensitivity
Acoustic emissions from two landslip areas in South Wales
Significant acoustic emissions have been recorded from two landslide sites, both subsequent to a major failure (Pantteg) and during continuous slow movement (Glynrhigos). Four distinct types of pedogenic AE have been recognised. The effects
Prediction of trace gas emissions and their climatic impacts : some geographical considerations
Toute tentative de prévision d'un changement climatique global, et de sa modulation à l'échelle régionale, se heurte à deux grandes incertitudes, l'une d'ordre socio-économique (quelle quantité de gaz à effet de serre sera émise), l'autre liée à une
Scales and networks of neoliberal climate governance : the regulatory and territorial logics of European Union emissions trading

This article analyses the ecological–economic geographies of globalization in order to demonstrate how regions could be connected with seemingly distant carbon emissions. It shows that emissions from emerging economies such as China might also

Contingencies of environmental justice : the case of individual mobility and Grenoble’s Low-Emission Zone
This article uses household-travel survey data to assess how a projected Low-emission zones (LEZs) in Grenoble, France could affect individuals’ mobility, specifically enquiring whether or not the impact would be socially differentiated and might
Dust emission from wet and dry playas in the Mojave Desert, USA
and at times are vulnerable to wind erosion and dust emission. Surface sediments at dry playas, on the other hand, are typically stable and hard and thus generally do not emit large amounts of dust when undisturbed by human activities. The emphasis
