It is not always evident how race matters to the study of food. The paper proposes how theories of race are being used in the literature. Most literature implicitly relies on the social construction of race to consider representations
Bedload, the transport of sediment remaining in contact with the stream bed, has mainly been studied from the perspective of the correlation between fluid driving forces and the responding sediment flux. Yet grain–grain interactions are important
and bedload should also be considered as a granular phenomenon. The AA. review progress made recently in the study of granular flows, especially on segregation and rheology, that better illuminates the nature of bedload. Mutual study of these phenomena may
and are located in the studied environment. The latter is analysed as a human habitat, while geographical area is treated as a place to locate investigated objects. The geographical research and morpho-functional structure is the equivalent
of the interdisciplinary study of spatial (natural and social) structure. The article reproduces morphology as a subject area of the disciplines for which the study of forms are common. Urban morphology as an art of urban forms is also discussed. – (BJ)

This paper presents an overview of past and current debates over the conceptualization of migration into rural areas – counterurbanization, and illustrates a shift in counterurbanization research from the study of the settlement system to the study
This study was performed at 3 eutrophic rivers in Southeast China aiming to determine the magnitude and patterns of dissolved N2O concentrations and fluxes over a seasonal (in 2009) and diurnal (24 h) temporal scale. The results showed that N2O
concentrations varied in the Fengle, Hangbu and Nanfei rivers, respectively, in the diurnal study performed during the summer of 2008. The study found that mean N2O concentration and estimated measured from the Nanfei River with serious urban wastewater pollution
was significantly higher than those from the Fengle and the Hangbu Rivers with agricultural runoff. The study demonstrated both N2O concentrations and fluxes exhibited seasonal and diurnal fluctuations. In addition, N2O accumulation rates over 3 consecutive days

The aim of this study is to characterize the synoptic weather patterns that justify fog water collection on the coast of Morocco and the Canary Islands. Furthermore, fog water collection is studied to evaluate its feasibility as a sustainable water
resource to satisfy the drinking water needs of a rural population in SW Morocco. The study period was from 2006 to 2010. Standard Fog Collectors (SFC) and the Quarter Fog Collectors (QFC) that were connected to automatic meteorological stations with which
An analytic multicriteria hierarchical approach to assess landslide vulnerability. Case study: Cornu village, Subcarpathian Prahova Valley/Romania
This study aims to test a semi-quantitative method of landslide vulnerability assessment in relation to population and road distribution, using an integrated multi-criteria method. This approach is focused on a case study from the Prahova Sub
Mass transfers, sediment budgets and relief development in cold environments: Results of long-term geomorphologic drainage basin studies in Iceland, Swedish Lapland and Finnish Lapland
comparison of the annual mass transfers occurring within the 4 investigated drainage basins summarises that there are differences between process intensities and the relative importance of different denudative processes within the study areas in Eastern
the sediment budget and trends of Postglacial relief development in selected study areas with given environmental settings.
This study aims at monitoring soil degradation process within the last four decades in the middle part of Nile Delta. Landsat ETM images and digital elevation model (DEM) are used to produce the physiographic map of the studied area at the landform
level. Land degradation rate, causative factors, degree, and land degradation status in the study area were assessed using GIS techniques. The results indicate that the most active land degradation factors in the studied area are; water logging
Interpreting luminescence data from a portable OSL reader: three case studies in fluvial settings
Optically stimulated luminescence (OSL) is a technique that has been applied from the mid-1980s, mainly for sediment dating. The study goal is to analyse only the luminescence signals (the total photon counts) in polymineral samples obtained after
light stimulation in the blue (BLSL) and infrared (IRSL) wavelengths using a portable OSL reader designed and built at the Scottish Universities Environmental Research Centre (SUERC). Three fluvial case studies – from Cambodia, Australia and Mexico
A GIS-based comparative study of frequency ratio, analytical hierarchy process, bivariate statistics and logistics regression methods for landslide susceptibility mapping in Trabzon, NE Turkey

The aim of this study was to evaluate the susceptibility of the occurrence of landslides in Trabzon province, situated in north east Turkey. This was achieved using the following 5 methods : the frequency ratio model, AHP, the statistical index (Wi
Soil studies of ancient and modern American Indian agricultural systems across the Southwest indicate that soil changes are highly variable, ranging from degradation to minimal net change, and to enhanced soil quality. Soil response trajectories
vary for a number of reasons. Studies of rock mulch soils indicate enhanced fertility, with elevated organic carbon, nitrogen, and available phosphorus levels, increased infiltration rates and moisture retention, and no evidence of compaction
. By contrast, cultivation effects vary widely for terraced soils. Although numerous studies have focused on irrigation canals, irrigated soils have received far less attention. Soil studies of irrigation systems along the Gila and Santa Cruz rivers of Arizona
Late Quaternary environmental change inferred from phytoliths and other soil-related proxies : case studies from the central and southern Great Plains, USA
The modern soils and paleoenvironmental study sites are located in Kansas and northern Oklahoma. Given the potential that opal phytoliths and other soil microfossils offer for paleoenvironmental reconstruction, the aim of this study was to analyze
Soil erosion rates in tropical villages : A case study from Lake Victoria Basin, Uganda
, the relationship between soil loss rates in these zones and the slope steepness is investigated as well as the evolution of soil loss rates over medium term (i.e. 5–50 years). Finally, the soil loss rates obtained in this study are compared with those from similar
This study focuses on spatial patterns of urban heat island (UHI) development within the rapidly changing urban landscape of the Delhi Metropolitan Region (DMR). To determine the role of local environmental factors in the shaping of microclimatic
