There is inadequate knowledge of the natural resources in the remote inaccessible protected areas of North East Region (NER) of India. Arunachal Pradesh, which is one of the state in NER is extremely rich in biodiversity and forms a part of the biodiversity hotspots in the Eastern Himalayas. However its biodiversity is under threat due to various factors like infrastructure development, changing socio-economic pattern and other external pressures. Therefore the need of the hour is to map the current biodiversity of the area as well as potential threats in order to conserve the natural resources and create detailed spatial databases. The objective of the present study is to map the land use land cover (LULC) of Mehao Wildlife Sanctuary (WLS) situated in Arunachal Pradesh using Remote Sensing and GIS technology. IRS LISS III satellite image has been used to extract LULC, vegetation maps using hybrid classification. Further a spatial database of the WLS was created which includes contour, drainage, spot height and elevation distribution maps.

This research work focuses on spatio-temporal pattern of motorcycle accidents in Anambra state, Nigeria. The study used mostly secondary data, accident records which were obtained from Federal Road Safety Commission Awka, Anambra state (RS 5.30). The data on motorcycle accidents were obtained for a period of ten (10) years (2007-2016). Analysis of variance (ANOVA) technique was employed in the examination of the statistical significance of the variation among the local government areas of the state. The result indicates that there is a significant variation in the number of motorcycle accidents among the local government areas of the state (F29, 189 = 2.609; p<0.05). Again analysis of variance was employed in the examination of the statistical significance of the variation of motorcycle accidents over time (2007-2016) in Anambra state. The result indicates that there is a significant difference in the number of motorcycle accidents from 2007-2016 (F9, 200= 13.210; p<0.05). Multiple regression analysis was employed in the examination of some of the characteristics of the local government areas of the state. It was observed that, there is a joint prediction of motorcycle accidents by a combination of some of the characteristics of the LGA of the state (p<0.05), the result implies that other characteristics of the Local Government areas of the state played little influence on the number of motorcycle accidents that occurred in 2011. The need for re-orientation of the land use pattern in the study area, better road network characteristics, Government should set up more police patrols for the highways in order to enforce road traffic regulation including speed limits and the need to establish Federal Road Safety Corps  archive where accident records will be kept, collated and processed are desirable.

Good classrooms, adequate security, school location, incessant strikes have been found to significantly influence school attendance and are baseline factors in determining student success. However, little is known about the influence of climate variability on school attendance in Nigeria. Thus, the focus of this study was to examine the effects of climate variability on school attendance in urban areas of Ibadan, Nigeria. Both primary and secondary data were used. A total of 450 students were sampled randomly from five public senior secondary schools in urban areas of Ibadan. The study revealed that the awareness of climate variability was high and not significantly different among students (x2= 20.465; p>0.05). Rainfall explained 38.9% and had a significant negative correlation with school attendance (r= -0.609; p<0.05), and this was largely due to the perceived threats that come along with high rainfall in the form of violent wind. The reality of climate variability has made students to devise means of coping with its adverse effects such as; sleeping naked and frequent drinking of water. The study concluded that there should be adequate enlightenment on effective environmental interaction to mitigate the adverse effects of climate variability.

Lake Burullus, as one of the northern deltaic lakes in Egypt, is an important economic, recreational and Fish breeding reservoir. The study used nine georeferenced stations to assess hydrogen sulphide (H2S) levels, its relationship with some selected hydrochemical parameters, and the implication on this lake’s biota.

The study reveals that areas mostly affected by drainage water with high load of organic matter, aid to the production of H2S into sediments and dispersion to water. The results indicate that H2S levels in lake sediments increase with increasing water temperature, biological oxygen demand (BOD) and load of organic matter (OM) in water. On the other hand, clear water areas with high oxygen levels aid in reducing levels of H2S in sediments as proved from correlation analysis. The positive correlation between variables as OM and BOD with H2S was observed using the distribution maps. The amount of different wastes, particularly in large quantities, increase the level of H2S, and therefore affected biota so it is highly recommended to treat wastewater to conserve the biodiversity of this lake.

With the Nigeria economy and her citizens over reliance on crude oil and its refined products, the use of petrol, diesel and kerosene in fuelling of generators and automobiles or for domestic cooking becomes very essential. Hence, constant visit to filling stations is necessary at one time or the other. This has in turn enthused the siting of so many filling stations and one is forced to wonder if they all complied with the standards required for their establishment. The question of where to buy fuel and which filling station is sited short of the regulatory standards can be appropriately answered using Geographic Information System (GIS). This study focuses on analysing the location of filling stations within Afikpo, in Ebonyi State Nigeria against the laws/regulations guiding their establishment. The coordinates of the filling stations were acquired with a handheld Global Positioning System (GPS) receiver and plotted on a georeferenced map in ArcMap environment of ArcGIS 10.2 software. All the analyses were performed in the ArcMap environment using spatial analyst, spatial statistics and proximity tools available in the software. The findings revealed that the filling stations are spatially distributed in a dispersed pattern. The results of the analysis reveals that 44.4% of the filling stations did not meet the criteria of 15 meters minimum distance from the pump to the edge of the road. 22.2% of the filling stations were sited too close (lesser than 100 meters) to a health care centre. 66.7 % % did not meet the criteria of 400 meter minimum distance to other stations when located on the same road side (with no road separation). This database created on filling stations provides a platform to help policy makers (regulatory agencies) in planning, management and effective monitoring/supervision. It is there recommended that the regulatory bodies should be proactive in the discharge of their duties.
