The reconciliation of engineering designs that do not have survey information, that involve accurate configuration of the proposed constructions at their respective locations on-site requires first a topographic survey to obtain the perimeter survey plan, which in turn, shows the area, shape, perimeter and orientation of the site; spot heights plan showing the existing ground levels thereby used to decide on suitable gradients and determine appropriate finished ground surface, coordinates of the turning points of outlines of the proposed constructions and their respective elevations. For that reason, this study determines the topography and drains the site for the Benin City Bus Rapid Transit (BRT) station in Oredo Local Government Area of Edo State. A topographic survey was carried out to produce topographic plans. The accuracy of the survey was computed to determine its reliability. The perimeter survey plan was plotted using AutoCAD Civil 3D Land Desktop Companion 2009 to present the area, shape, perimeter and orientation of the site. The TIN method was used for the computation of the volume of earthworks. The existing and the finished ground surfaces, vector, as well as the flow direction plans, contour plans and the 3D surface maps were plotted using Surfer 11 to show graphically the existing and the proposed topography of the site. A network of drainages was established to drain the site. The study has shown that the site can be drained in two ways, into the moat behind it and existing drainage along Obakhavbaye.

This study assessed the geospatial impacts of sand mining activities in Benin City, Edo State, Nigeria. There are thirty five (35) burrow pits in Benin and eleven (11) were used for the study. Similarly, three (3) distinct datasets and sources were used to determine the spatial extent of environmental degradation as a result of sand mining activities in Benin City. The first data set was the 19th January, 2019 satellite imagery of each of the mining sites. This high resolution remotely sensed data was used in the determination of areal extent of the sand mining sites. The second set of data was the Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) 30meters resolution digital elevation model (DEM). The ASTER-DEM was used as an input dataset in the determination of the volume of sand that have been mined in each site and compilation of three – dimensional model (3D Model) of each the sand mining site. The third set of data was the geographic coordinates of the mining sites. They were sourced from field survey with the use of global positioning system (GPS).The study concluded that sand mining and development cannot be entirely separated but mining should be done in a sustainable manner with less of environmental degradation. It is recommended that miners should be regularly sensitized by the government on environmental degradation and about the fragile nature of the environment. The government regulatory body should ensure that Environmental Impact Assessment (EIA) is carried before mining pits are approved for mining activities. Also illegal burrow pits should be short down to check environmental degradation.

The influence of humans on biodiversity at the genetic, species, community, and ecosystem levels is enormous. This is even more impactful on plant populations, which, being immobile, are at the mercy of their immediate environment. Digitaria horizontalis is a very common grass species in Benin City. Its ruderal nature accounts mostly for its widespread. The current study investigated the existence of possible genetic diversity of the grass in built environment in Benin City. Plant samples were randomly collected from 21 built environment locations within 6 Local Government Council Areas that make up Benin City. Test plants were allowed to acclimatize in experimental bowls and then allowed to grow for 4 weeks after which morphological characteristics were determined. Genetic diversity was determined by Random Amplification of Polymorphic DNA. Significant differences in plant height (33.0 – 59.0 cm) occurred when plants were compared based on location of collection. Changes in patterns of the association with weeds within the vicinity of the test plant was observed. The most prevalent plant species associated with the test plant was Pennisetum purpureum with a 12.18% prevalence. RAPD analysis using primer OPA 04 revealed a locus (about 600bp) that was absent in one or more of the locations with minimum disturbance. This 600pb fragment was however observed in most samples from highly built up and trampled environments. Primer OPA 03 showed monomorphic bands in 2 test samples with a band size of 400bp. It is therefore reported that there is an existence of the genetic diversity in a landscape of grass species (Digitaria horizontalis) found in different built environment in Benin City, Edo State, Nigeria.
