Tawey Ibrahim A. Adesoji Ismail A. Garba <p>The current study was designed to provide a consistent and detailed understanding of the Structural disposition and magnetic source depth of Sheet 266, south-east Nigeria in the Auchi region by applying three source edge mapping techniques: horizontal gradient magnitude; tilt derivative and Euler deconvolution to aeromagnetic data obtained from Nigeria Geological Survey Agency Abuja (NGSA). To achieve the above objective, there was a need to correct the latitudinal effect on data obtained at low latitudes just as the present case, the total magnetic intensity (TMI) data was reduced to the pole (RTP) and regional magnetic anomalies were extracted from the RTP data to obtain the residual anomaly data using the upward continuation technique. To establish the boundaries of the magnetic sources, various source edge mapping techniques such as Analytic signal (AS), Horizontal Gradient Magnitude (HGM) and Tilt Derivative (TDR) were applied. A strong correlation between these techniques has been found, suggesting that their incorporation may contribute to delineating the structural mechanism of the study area. A comprehensive structural map based on the findings was therefore built. The key tectonic patterns in the study region are typically interpreted to predominantly ENE-WSW trend followed by WNW-ESE trend. In the study area, depth to magnetic source estimation using 3D Euler deconvolution and source parameter imaging (SPI) has also shown that the two techniques complement each other with depth estimation and general depth to magnetic source was 50 m in the basement portion of the study area and &gt;2000 m in sedimentary portion as seen from both SPI and 3D Euler deconvolution techniques.</p> 2020-10-21T00:00:00+00:00 ##submission.copyrightStatement## Assessment of Ground Water Quality (A Case Study of Mando, Igabi Local Government Area, Kaduna State) 2020-11-20T10:44:17+00:00 A. A. Ijah E. J. Zakka O. N. Oladele O. E. Olagunju <p>This study shows the assessment of ground water quality in Mando Area of Igabi Local Government Area of Kaduna State. A total of twenty (20) samples of water (Ten (10) bore-hole water samples and Ten (10) hand dug well water samples) were collected randomly from different locations within the study area. The analysis of these samples was carried out in the Water Quality Laboratory of National Water Resources Institute Kaduna except for the the analysis of the heavy metals which was carried out at the Federal Ministry of Agriculture and Rural Development, Kaduna State. The result from the analysis shows differences in the average level of physiochemical and bacteria concentration for both categories of water samples. But this difference in concentration still falls within the permissible limit of both the World Health Organization (W.H.O) and (NSDWQ) standard for water quality, thus acceptable. The concentration of heavy metals like Lead and Chromium is same for both samples in the study area which is above the permissible level of WHO and NSDWQ standards. The average level of physiochemical and bacteria concentration of both categories of samples are thus; for bore-holes water sample: Electrical Conductivity is 109.56 ℳs/cm, Turbidity is 0.07 NTU, Total Dissolved Solid is 54.5 ppm, Temperature is 25.2℃, Colour is 8.6 TCU, Ph is 6.4, Total alkalinity is 51.3, Nitrate is 25.72, Chloride is 22, Total Hardness is 39.52, Salinity is 35.8, Fluoride is 0.53, Iron is 0.012, Sulphate is 3.6, Lead is0.4, Chromium is -0.068, Total coliform is 13.8 and that of the hand dug well in same sequence is thus; 183.39, 1.76, 90.22, 25.15, 14, 6.6, 30.2, 42.56, 23.4, 56.8, 38.7, 0.24, 0.012, 2.3, 0.4, - 0.078 and TNTC.s</p> 2020-11-20T00:00:00+00:00 ##submission.copyrightStatement## Desertification in Western Rajasthan (India): Causes, Effects and Mitigation Measures 2020-11-23T10:43:25+00:00 Tukur Umar Yusuf Satish Kumar Ameta Abdulwasiu Usman Adamu Tukur Yakubu Gambo Hamza <p>Desertification is a type of land degradation in drylands whereby biological productivity is reduced due to natural or anthropogenic factors converting them more arid. Thus, it is emerging global environmental issues and problems, India inclusive. It is a threat for both human beings and ecological systems. The various causes of desertification are attributed to climatic change which is the combination of both natural and anthropogenic factors. These causes leads to destruction of vegetation that result in extinction of species, soil erosion and soil infertility, increase vulnerability of natural disasters, pollution of soil, air and water, rise of famine, poverty, forcing mass migration and social conflicts. Rajasthan state of India due to its proximity to Thar desert in western part of Rajasthan also gets impacted to great extent by the effects of desertification and industrialization to as Rajasthan has a rich source of limestone and gypsum. The actions of desertification in western Rajasthan leads to destruction of ecological system and loss of biodiversity. The mitigation of desertification effects is critical and essential in meeting the millennium development goals. Such that the human well-being of dry land people, which constitute of about 90% of whom are in developing countries of the world, including India, lagging significantly behind. The combination of high variability in ecosystem conditions in dry lands and high level of poverty leads to situation where societies are vulnerable to a further decline in human well-being and existence. Hence mitigating desertification, thus facilitates eradication of extreme poverty, integrated land and water management, protection of Vegetation cover as envisioned in the millennium development goals (MDGs). Hence, individuals, communities, national and international, NGOs have to act actively to mitigate these effects and causes of desertification as a whole.</p> 2020-11-23T00:00:00+00:00 ##submission.copyrightStatement##
