    This research work examine the analysis of urban growth using remote sensing and GIS Techniques in Kabong, Jos North L.G.A, Platue State, Nigeria . Data for the study were sourced from the primary and secondary data source. The finding of the study revealed that the most substantial change was the transformation of vacant barren land and rock outcrop to imperious built-up areas. Classification results shows the built up cover increased from 24462(9.8) in 1998 to 552.69 Ha922.2%) in 2008 to 2018 to 1071.27Km2 (143.18). results present that among the changes in Kabong increase in built up area from 9% to 43.18% and decreased off bare surface and vacant land had serious changes on the landscape as presented on the maps, the main changes of land use in these areas can be described as other type of land use covering into urban land, it is recommended that proper monitoring of the pattern and rate of urban expansion should be adhere strictly so as to achieve sustainable urban development.

    Evaluation of the Variation in the Level of Compliance of Kaduna Refinery and Petrochemical Company (KRPC
    (Department of Environmental Management, Nasarawa State University Keffi, 2019-07-20) Anzaku, I.M.; Alkali, Mohammed; Umar, Garba; Umbugus, Abraham; Ahmadu, Jibrin
    This study evaluates the level of compliance of Kaduna Refinery and Petrochemical Company (KRPC) to United Nation Environmental Safety Standard for effiuent Management. Waste water samples were collected from eight sampling points within the study area which comprised of the following: effluent sample before treatment, effluent sample after treatment, KRPC effluent discharge point, a point downstream after the refinery facility, and 4km downstream after the refinery facility. The data collected were subjected to Laboratory analysis in the Kaduna Environmental Protection Authority Laboratory. The results generated from laboratory analysis were then subjected to statistical analysis which included ANOVA and Plots of mean variation. Research findings revealed that most of the parameters measured show a significant variation between the sampling points and within the months. The plots of mean variation on the other hand show that the concentration of these parameters varies progressively with distance from the point of the refinery facility. The following recommendations would minimize the load of pollutants on Romi River; the activities of other industries in Romi-Rido environs should be critically identified and assessed; and there is a need for the National bodies entitled with the role of assessing the activities of industries to develop a form of sanctioning against any industry that refuses to adhere to the standard environmental protection legislation, among others.
