Abstract: A combination of petrography and geochemistry (XRF, ICP-OES and ICP-MS) was utilized in order to investigate the magma source(s), magma evolution and petrogenesis implications of the Kgwebe Volcanic Formation (KVF) rock units in the Ghanzi-Chobe Belt portion of the Kalahari Copper Belt (NW Botswana). Based on their texture, the KVF rock units were discriminated into amygdaloidal rocks, porphyritic mafic flows, pyroclastic rocks, porphyritic subvolcanic bodies, quartz-feldspar ...
Abstract Solid waste is one of the major challenges facing Nigerian cities. Waste management problem is complex because it involves a multitude of scientific, technical, economic and social factors. However, this essential service is not effectively and properly performed by the concerned bodies in Uyo Metropolis of Akwa Ibom State. Data were collected from both secondary and primary sources. Data on the existing solid waste management system in Uyo Metropolis were collected from primary sou...
Groundwater quality in Neke area of southeastern Nigeria was investigated applying multivariate statistical analyses using Statgraphics Centurion XVII, ArcGIS 10.2.2 and Surfer 10 software on hydrochemical and bacteriological data from 25 groundwater samples over land cover of about 1283km2 ,in order to unravel the factors influencing ground water quality. From the correlation analysis, Ca2+, Mg2+, K+, and S042- appear to be the main contributors of the ground water TDS, Ca2+ shows a high cor...
Physico-chemical, multivariate and bacteriological analyses were integrated to assess the impact of onsite sanitary sewage and agricultural waste on groundwater quality in Ikem and its environs using Rockworks16, Statgraphics Centurion XVII, ArcGIS 10.2.2 and Surfer 10. Results of the physicochemical analysis suggest that groundwater samples in the study area acidic, with very few samples having electrical conductivity and total dissolved solids above WHO standard for drinking water. The ...
Water resources management has passed through many stages over the millenium. In the process, Integrated Water Resources Management (IWRM) was discovered and embraced as a panacea for the world’s water resources problems. Many countries in the developing realm have adopted IWRM with measurable success. Experiences in the developing countries have never come out very clear. This study attempts to have insight into how the general principles of IWRM performs at local situations in Nigeria. Th...
Abstract This study investigates the landuse conflict between cattle herdsmen and farmers in Plateau state, Nigeria. It analyzed the landuse and landcover dynamics of the study area between 1986 and 2014 and identified the trance-humance routes, grazing corridors and conflict zones in the area. It went further to determine the optimal farming and grazing zones using GIS multi-criteria analysis. The study made use of Landsat images of 1986, 2001 and 2014, elevation data (SRTM) of 2014, topogr...
Lake Chad (in French: Lac Tchad) is a large, shallow lake in Africa. It is economically very important, providing water to more than 20 million people living in the four countries which surround it — Chad, Cameroon, Niger and Nigeria. It is located mainly in the far west of Chad, bordering on north eastern Nigeria. The Chari River is its largest source of water, providing over 90% of Lake Chad's water. The lake possesses many small islands and mud banks, and its shorelines are largely compo...
In the process of man’s consumption of natural resources in his natural environment, a number of stress is created which affects adversely the quality of the environment in which he lives. In this paper an attempt has been made to identify the various methods through which public awareness that are considered effective as well as the strategies for their implication are discussed in the light of the achievement of a sustainable environment in Nigeria. In its introductory section, attempts h...
Twenty-five years ago the Union of Concerned Scientists and more than 1,500 scientists, including the majority of living Nobel laureates in the sciences, penned the 1992 “Scientists’ Warning to Humanity.” These scientists called on humankind to curtail environmental destruction and cautioned “a great change in our stewardship of the Earth and the life on it is required, if vast human misery is to be avoided.” In their manifesto, they showed that humans are on a collision course with...
This study analyzed the spatiotemporal pattern of settlement expansion in Abuja, Nigeria, one ofWest Africa’s fastest developing cities, using geoinformation and ancillary datasets. Three epochs of Land-use Land-cover (LULC) maps for 1986, 2001 and 2014 were derived from Landsat images using support vector machines (SVM). Accuracy assessment (AA) of the LULC maps based on the pixel count resulted in overall accuracy of 82%, 92% and 92%, while the AA derived from the error adjusted area (EAA...
The Cross River State Government in Nigeria is proposing to construct a ‘‘Cross River Superhighway’’ that would bisectcritical remaining areas of tropical rainforest in south eastern Nigeria. We offer and evaluate two alternative routes to the superhighway that would be less damaging to forests, protected areas, and biological diversity. The first alternative we identified avoids intact forests entirely while seeking to benefit agriculture and existing settlements. The second altern...
The Chad basin which covers an area of about 2.4 million kilometer square is one of the largest drainage basins in Africa in the centre of Lake Chad .This basin was formed as a result of rifting and drifting episode, as such it has no outlet to the oceans or seas. It contains large area of desert from the north to the west. The basin covers in part seven countries such as Chad, Nigeria, Central African Republic, Cameroun, Niger, Sudan and Algeria .it is named Chad basin because 43.9% falls...
The successful execution of the project is expected to have both positive and negative impact on the physical, chemical and biological environment of the site for the proposed solar farm. Consequently, d-ExcelChris Renewable Energy Limited has been consulted to prepare a Preliminary ESIA in line with the World Bank Standard, Operational Performance Standards and International Finance Corporation (IFC), and also the national and local regulations. The national regulation which is Nigerian EIA ...
This paper gives an overview of the Pluto debate in solar system. It explains the new definition of planet and how it affects students in the elementary schools. The paper also seeks the active participation of stakeholders in educating people on new discoveries in space explorations. Introduction The composition of planets in the solar system has been a point of debate among astronomers, planetary scientist, astrophysicist etc on the status of some planets. It is known that the planets, sat...
ABSTRACT The purpose of fire fighting training is to highlight the fundamentals of fire fighting to enable personnel fight incipient fire. Fire is a very rapid chemical reaction between oxygen and a combustible material, which results in the release of heat, light, flames and smoke; or a combustion process of oxidation characterized by the production of heat, flame and smoke. Fire outbreak remains one of the dangerous and costliest experiences one can ever encounter. Fire is gene...
