Environmental problems like desertification, deforestation, and pollution have become important paradigms in Nigeria in the last three decades. Similarly, Government, Non-governmental Organizations, corporate bodies and individual’s interests in reducing, stemming and / or mitigating the consequences of environmental degradation is very commendable. Many of the generally acknowledged global environmental problems (greenhouse warming, ozone depletion, soil erosion, chemical management, acidi...
The search for crude oil has expanded in many parts of the world with positive results in some members of the Organization of the Petroleum Exporting Countries (OPEC). Regardless of the numerous socio-economic gains from the discovery of crude oil, spills sometimes occur during production operations, or due to accidental discharges, leakages from corroded bunkers and transport vessels, and human errors. These spills contaminate the surrounding environment and negatively affect the ecosystem (...
A measure of the total amount of carbon dioxide (CO2) and methane (CH4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system or activity of interest is known as Carbon footprint.
Fire emergency has become a recurring phenomenon in school environment. Unlike the developing countries, the availability of preparedness measures in most of the schools in developed countries has tremendously reduced the impact of incidences (U.S. Fire Administration, National Fire Data Centre, 2007). In developing countries, however, the contrary is the case, the lack of or inadequate preparedness measures in most schools, and the increase in fire incidents are raising alarm. The physical, ...
The study was carried out to analyze the vulnerability and adaptive measures to flood disaster in Rivers State focusing on Ahoada west local government area. Structured questionnaire was used in collecting data from a total of number of one hundred and eighty (180) respondents in Ahoada west local government area out of which one hundred and seventy two (172)were retrieved. Data for this study were collected from primary and secondary sources. The primary source was from structured ques...
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...
Absract Consumption of sachet water and the resultant effect on human health have prompted severalstudies. Quality assessment of various sachet water brands marketed in Oju Metropolis of BenueState was carried out in this study. Five sachet water brands (SWB) were selected and evaluatedwith the paqualab kit for two weeks to investigate the physico-chemical, microbiologicalcontaminants and to compare the quality parameters with public water source (pip...
Abstract The current ecological status of the Kagoro/Tsonje riparian forest was assessed and information was gathered on the flora and bird fauna, water quality parameters and soil status. Other data collections were phytoplankton types and population. Physiocochemical properties of the soil were tested .Modified Whittakker plots were used to evaluate woody species for density, diversity and similarity measure. One metre by one metre ...
ABSTRACT This research on assessment of land use/land cover change and floristic composition of Kuwanka Banza Forest Reserve in Kebbi State was carried out to determine percentage change and extent of forest cover of the Reserve area between 1984 and 2013, the current land uses in the forest area as well as the distribution and abundance of woody species. Remote sensing techniques were used in this study, where 1984 and 2013 landsat imagries were processed�...
ABSTRACT This study investigated the practices of health and safety management in construction industry focusing on risk assessment, communication and control. To achieve this purpose, the study focused on high-rise building under construction. Three construction sites were selected for detailed study using purposive sampling. 405 questionnaires were prepared and administered to the regulatory body, construction company and the labourers’ at the site. Observation checklist was used as a mea...
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 ...
ABSTRACT Floods are the most devastating of all natural disasters, accounting for about one-third of theeconomic losses and over half of the deaths associated with natural disasters worldwide.Flooding in Lagos has become a frequent hazard which is caused by the bad condition of thedrainage systems along the road and the unavailability of water channels to contain excesswater in case of heavy rain. The flood problem is worsened with heavy r...
The study evaluates the problems of solid waste management in Nigeria. The study has the following objectives: to examine the consequences of poor solid waste management in Nigeria, a case study Gwagwalada Area Council, Abuja and to identify the strategies that has been adopted in solid waste management in Nigeria. It also explained the mode of data collection and analysis; data for this study was collected from the respondents through the use of questionnaires. Questionnaires were shared...
Flood modelling and mapping typically entail flood frequency estimation, hydrodynamic modelling and inundation mapping, which require specific datasets that are often unavailable in developing regions due to financial, logistical, technical and organizational challenges. This review discusses fluvial (river) flood modelling and mapping processes and outlines the data requirements of these techniques. This paper explores how open-access remotely sensed and other geospatial datasets can su...
