Socio-Environmental Considerations At The Usuma Reservoir In Abuja, Nigeria, Fanan Ujoh Mr, James Ikyernum Mr, Olarewaju O. Ifatimehin Dr
Dr. Fanan Ujoh
Reservoirs are Man’s attempt towards water re-distribution from regions/seasons of abundance/surplus to regions/seasons of scarcity. This study focuses on socio-environmental impacts of the Lower Usuma dam in Abuja, on its four surrounding communities. Stratified random sampling technique was employed in the administration of a questionnaire to 200 respondents. Using descriptive statistics and the student t-test for the analysis, the study discovered that: (i) there has been no significant improvement in infrastructure provision by Government; (ii) cases of water-borne diseases are high; (iii) the communities have lost land for cultivation; and, (iv) the communities believe that the resettlement scheme is not …
Mapping The Surface Characteristics Of The Mojave With Remote Sensing For Terrestrial Habitat Modeling, Scott A. Nowicki
Mapping The Surface Characteristics Of The Mojave With Remote Sensing For Terrestrial Habitat Modeling, Scott A. Nowicki
Scott A Nowicki
High-resolution ecological and climate modeling requires quantification of surface characteristics such as rock abundance, soil induration and surface roughness at fine-scale, since these features can affect the micro and macro habitat of a given area and ultimately determine the assemblage of plant and animal species that may occur there. Our objective is to develop quantitative data layers of thermophysical properties of the entire Mojave Desert Ecoregion for applications to habitat modeling being conducted by the USGS Western Ecological Research Center. These research efforts are focused on developing habitat models and a better physical understanding of the Mojave Desert, which have …
Do We Really Need New Policies? A Study On Soil Sealing In Egypt, Ahmed Harb Rabia
Do We Really Need New Policies? A Study On Soil Sealing In Egypt, Ahmed Harb Rabia
Ahmed Harb Rabia A.H. Rabia
Egypt has the lowest area of agricultural land per individual in Africa. The agricultural land stands for a total of approximately 3.5 million ha which characterized about 3.5% of the total area of Egypt in 2007. The urban encroachment over arable productive agricultural land in Egypt is common and is called (urban desertification). Therefore, the annual loss of arable land to urbanization is 1.2%. This indicates a serious situation to the agricultural area. the Academy of Scientific Research & Technology (1994) has reported that during the period from 1978 to 1984, the annual expansion rates of the dwelling area ranged …

This paper presents the results of the PM2.5 and PM10 mass concentration measurements in an urban air and results obtained from the additional chemical analysis concerning carbon and sulfur content of the collected dust samples. Dust samples were collected at the measuring point located on the roof of five-storey building at the AGH University of Science and Technology in Krakow, Poland (the center of the urban area of the city). In the scope of this study the relations between the carbon and sulfur content within the collected dust samples were determined in the function of the dust fraction content and …
Ultimate Detectability Of Volatile Organic Compounds: How Much Further Can We Reduce Their Ambient Air Sample Volumes For Analysis?, Ki-Hyun Kim
Ki-Hyun Kim
To understand the ultimately lowest detection range of volatile organic compounds (VOCs) in air, application of a high sensitivity analytical system was investigated by coupling thermal desorption (TD) technique with gas chromatography (GC) and time of flight (TOF) mass spectrometry (MS). The performance of the TD-GC-TOF MS system was evaluated using liquid standards of 19 target VOCs prepared in the range of 35 pg to 2.79 ng per μL. Studies were carried out using both total ion chromatograms (TIC) and extracted ion chromatograms (EIC) mode. EIC mode was used for calibration to reduce background and to improve signal to noise. …

Ahmed Harb Rabia A.H. Rabia
Soil erosion is one of the major causes of land degradation in arid and semi-arid areas like Ethiopia, including Tigray Highlands, which is highly affected by the risk of desertification. Tackling on-site effects of soil erosion requires understanding of the rates of soil loss as well as identification of the major controlling factors that accelerate or slow down these processes. The study aims to quantify the soil loss by erosion process and to specify the main factor affecting the Erosion development in the study area. The Study area was Kilte Awulaelo District which is situated in the eastern part of …

A Gis Based Land Suitability Assessment For Agricultural Planning In Kilte Awulaelo District, Ethiopia, Ahmed Harb Rabia A.H. Rabia
Ahmed Harb Rabia A.H. Rabia
Land Suitability refers to the ability of a portion of land to tolerate the production of crops in a sustainable way. Such kind of analysis allows identifying the main limiting factors for the agricultural production and enables decision makers to develop crop managements able to increase the land productivity. Objectives of this study were to develop a GIS based approach for land use suitability assessment which will assist land managers and land use planners to identify areas with physical constraints for a range of nominated land uses. Also to help identify the management requirements that will ensure that a particular …
Modeling Of Soil Sealing By Urban Sprawl In Wukro, Ethiopia Using Remote Sensing And Gis Techniques, Ahmed Harb Rabia A.H. Rabia
Modeling Of Soil Sealing By Urban Sprawl In Wukro, Ethiopia Using Remote Sensing And Gis Techniques, Ahmed Harb Rabia A.H. Rabia
Ahmed Harb Rabia A.H. Rabia
Soil sealing is the covering of the soil surface with materials like concrete and stone, as a result of new buildings, roads, parking places but also other public and private space. Soil sealing by urban sprawl continues to increase all over the world where the area of urbanized land is increasing even more rapidly than the population. The degree of sealing is associated to the land use type and the density of population. Techniques of Remote Sensing and Geographical Information System (GIS) have been used widely to measure urban sprawl and to analyze the spatial features and unique mechanism of …

Gis Spatial Modeling For Land Degradation Assessment In Tigray, Ethiopia., Ahmed Harb Rabia A.H. Rabia
Ahmed Harb Rabia A.H. Rabia
Land degradation can be described as reduction in the present and prospective land quality and production, due to natural or anthropogenic dynamics. This phenomenon is one of the most important problems facing farmers and decision makers in several countries. This study aims to use GIS spatial modeling to quantify land (physically and chemically) degradation in the study area based on remotely sensed and field survey’s data. A GIS spatial model has been developed based on the LADA- FAO methodology to apply a land degradation assessment in the study area. Final land degradation map has been produced by combining the outputs …
An Investigation Of Voluntary Corporate Greenhouse Gas Emissions Reporting In A Market Governance System: Australian Evidence, Michaela Rankin, Carolyn Windsor, Dina Wahyuni
An Investigation Of Voluntary Corporate Greenhouse Gas Emissions Reporting In A Market Governance System: Australian Evidence, Michaela Rankin, Carolyn Windsor, Dina Wahyuni
Carolyn Windsor
Purpose – Institutional governance theory is used to explain voluntary corporate greenhouse gas (GHG) reporting in the context of a market governance system in the absence of climate change public policy. This paper seeks to hypothesise that GHG reporting is related to internal organisation systems, external privately promulgated guidance and EU ETS trading.
Design/methodology/approach – A two-stage approach is used. The initial model examines whether firms’ GHG disclosures are associated with internal organisation systems factors: environmental management systems (EMS), corporate governance quality and environmental management committees as well as external private guidance provided by the Global Reporting Initiative (GRI) and …

Impact Of Signal-To-Noise Ratio In A Hyperspectral Sensor On The Accuracy Of Biophysical Parameter Estimation In Case Ii Waters, Wesley J. Moses, Jeffrey H. Bowles, Robert L. Lucke, Michael R. Corson
Wesley Moses
Errors in the estimated constituent concentrations in optically complex waters due solely to sensor noise in a spaceborne hyperspectral sensor can be as high as 80% or more. The goal of this work is to elucidate the effect of signal-to-noise ratio (SNR) on the accuracy of retrieved constituent concentrations. The large variation in the magnitude and spectral shape of the measured signal due to the wide range of constituent concentrations in coastal waters complicate the impact of SNR on the accuracy of estimation. Due to the low reflectance of water, especially in the near infrared region, the actual SNR encountered …
