Author  :  Sten Gillner & Sandra Korn & Mathias Hofmann & Andreas Roloff Year  : 2017 Title  :   Contrasting strategies for tree species to cope with heat and dry conditions at urban sites Journal  :  Urban Ecosyst Comment   :  Measurements of leaf gas exchange, leaf water potential, leaf surface temperature and chlorophyll-fluorescence were used for identification of specific response of Corylus corluna L., Ginkgo biloba L., Liriodendron tulipifera L., and Tilia cordata Mill. ‘Greenspire’.   The summer months in 2013 with a period of heat and drought over eight weeks only interrupted by two rainy days were appropriate to access tree’s strategies to cope with low water availability.   During the measurement period, the influence of high temperatures, high values of vapor pressure deficit (VPD) and low soil water availability on stomatal conductance, water-use efficiency (WUE) and leaf water...

Author  :  Hamed Majidzadeh, B. Graeme Lockaby, Robin Governo Year  : 2017 Title  :  Effect of home construction on soil carbon storage-A chronosequence  case study Journal  :  Environmental Pollution Comment   :  Previous research documents a significant  reduction in SOC and TN, however, it is unclear if this decrease is a result of top soil  removal or long-term soil sealing.  In this study, soil biogeochemical properties were quantified beneath  homes built on a crawl space at two depths (0-10 cm, and 10-20 cm). All homes, 11-114 years in age,  were sampled in the Piedmont region of Alabama and Georgia, USA.  The difference in SOC  beneath homes and adjoining urban lawns showed a quadratic relation with age.  Maximum SOC loss occurred at approximately fifty years. The same pattern was observed for  Microbial  biomass carbon  : C ratio  suggesting that th...

Author  :  Subhadip Ghosh, Bryant C. Scharenbroch, Lai Fern Ow Year  : 2016 Title  :  Soil organic carbon distribution in roadside soils of Singapore Journal  :  Chemosphere Comment   : They  characterized the soil organic carbon  (SOC) in roadside soils across the city-state of Singapore. We tested three hypotheses that SOC contents  (concentration and density) in Singapore would be positively related to above ground tree biomass, soil  microbial biomass and land-use patterns.  Singapore's roadside soils represent 4% of Singapore's land, but store 2.9 million Mg C  (estimated range of 0.3-11 million Mg C). This amount of SOC is equivalent to 25% of annual anthropogenic C emissions in Singapore. Soil organic C contents in Singapore's soils were not related to  above ground vegetation or soil microbial biomass, whereas land-use patterns to best explain variance in  SOC in Singapore's roads...

Author  :   Christopher D. Elvidge, Benjamin T. Tuttle, Paul C. Sutton, Kimberly E. Baugh, Ara T. Howard, Cristina Milesi, Budhendra L. Bhaduri  and Ramakrishna Nemani  Year  : 2007 Title  :  Global Distribution and Density of Constructed  Impervious Surfaces Journal  :  Sensors Comment   : They  present the global inventory of the spatial distribution and density of constructed impervious surface area (ISA). Examples of ISA include roads, parking lots, buildings, driveways, sidewalks and other man-made surfaces.  They found that 1.05% of the United States land  area is impervious surface (83,337 km2) and 0.43 % of the world’s land surface (579,703  km2) is constructed impervious surface.  China has more ISA than any other country  (87,182 km2), but has only 67 m2 of ISA per person, compared to 297 m2 per person in the  USA. The distribution of ISA in the world’s primar...

Author  :   M. Hedblom & F. Lindberg & E. Vogel & J. Wissman & K. Ahrné Year  :  2017 Title  :  Estimating urban lawn cover in space and time: Case studies in three Swedish cities Journal  :  Urban Ecosyst Comment   :   They review the existing literature of lawn  cover in cities and the different methodologies used for cover  estimation. They found both pros and cons with NDVI and  LiDAR data as well as manually interpreted aerial photos.  During 50 years lawn area almost doubled in relative  cover and 56% of them were continuously managed.  Since  lawns constitute large parts of the urban greenery and are costly  to manage it is highly relevant to consider their social, ecological  and cultural value compared to alternatives, e.g., meadows  with less intensive management.

Author  :   M. Rial, A. Martínez Cortizas, L. Rodríguez-Lado Year  :  2017 Title  :  Understanding the spatial distribution of factors controlling topsoil organic carbon content in European soils Journal  :  Science of the Total Environment Comment   :  They present a modelling procedure for mapping and monitoring SOC contents  that uses Visible-Near Infrared (VNIR) spectroscopic measurements and a series of environmental  covariates to ascertain the key environmental processes that have a major contribution into SOC sequestration  processes.  Their results show that it follows a geographically non-stationary process in which the influencing environmental  factors have different weights depending on the spatial location.  This implies that SOC stock modelling  should not rely on a single model but on a combination of different statistical models depending on the  environment...

Author  :   Xiaolin Dou, Xiaoli Cheng, Ping He, Ping Zhu, Wei Zhou, Ligang Wang Year  :  2017 Title  :  Dynamics of physically- separated soil organic carbon pools assessed from δ13C changes under 25 years of cropping systems Journal  :  Soil & Tillage Research Comment   :  They combined soil fractionation with C isotope  analyses to investigate the SOC dynamics of the various soil fractions in a black soil of Northeast China after 25  years of tillage. Soil samples from the initial condition (CK) and 2 cropping treatments including continuous maize cropping (MM), maize–soybean rotation (MS) were separated into 4 aggregate sizes (< 53 μm, 250–53 μm, 2000–250 μm, and >2000 μm). The MS system was more  beneficial for the SOC accumulation in macroaggregates (> 250 μm) than the MM system because of enhanced  SOC in heavier fractions (iPOM and mSOM); this was probably induced by the ...

Author  :   Wycliffe Tumwesigye, John Wasige, Groen Thomas Year  :  2015 Title  :  Effect of land use change and slope position on soil organic carbon in Kitabi Watershed Rwanda Journal  :  Journal of Scientific and Innovative Research Comment   :  The aim of this study was to investigate the effect of LUC and slope positions on SOC stocks in Kitabi watershed. Slope positions were derived from the DEM using Topographic Position Index (TPI) tool and the output raster was overlaid with the LUC map to identify sample strata. Results indicate that LU types significantly affect SOC stocks (p < 0.001) while slope position does not (p =.491). The interaction of LU and slope position has no significant effect on SOC stocks across the three land use types (p = .061).

Author  :   KyungsooYoo and Ronald Amundson Year  :  2005 Title  :  Erosion of upland hillslope soil organic carbon:  Coupling field measurements with a sediment transport model Journal  :  Global Biogeochemical Cycles Comment   :  They combined a hillslope sediment transport  model with empirical soil C measurements to quantify the erosion and temporal storage of  soil organic carbon (SOC) within two grasslands in central California.  The eroded soil  accumulates on depositional slopes. The long term SOC accumulation (or C sink) rates  are 1.9 g C m-2 yr-1 in the Tennessee Vally hollow and 1.7–2.8 g C m-2 yr-1 in the Black Diamond footslope. They found that the hillslope C sink is driven primarily by the burial of in situ plant  production rather than preservation of eroded SOC, a finding that differs from existing  hypotheses. This study suggests that erosion and deposition...

Year  :  2016 Title  :  Remote sensing-based artificial surface cover classification in Asia and spatial pattern analysis Journal  :  Science China-Earth Sciences Comment   :  .According to their results, the urban built-up area was 18.18×104 km2 , accounting for 0.59% of the total land surface areas in Asia; urban impervious surfaces were 11.65×104 km2 , accounting for 64.09% of the total urban built-up area in Asia. Vegetation and bare soils accounted for 34.56% of the urban built-up areas.
