  1. 2015:  Assessment of Prevailing Safety Management Practices among Petrol Filling Stations in Ghana: A Case Study in Agona Nkwanta, Inchaban and Sekondi-Takoradi

This research was carried out to investigate the prevailing safety management practices at some selected petrol filling stations (PFS) in Agona Nkwanta, Sekondi-Takoradi and Inchaban in the Western Region of Ghana. This was necessary due to the recent outburst of flames at PFS in Ghana especially the June 3, 2015 catastrophic explosion at GOIL filling station around Kwame Nkrumah Circle, Accra in which the Ghana National Fire Service confirmed the loss of about 160 human lives with about 1 000 affected persons. A mixed methodological approach including structured and face-face interviews, observations, surveys and the use of GPS were employed in the study. Though safety management was considered important among the OMCs especially the Multinational OMC, yet safety policy enforcement was weakest.

 

  1. 2015: Municipal solid waste landfill site selection in the Sekondi-Takoradi metropolis of Ghana using fuzzy logic in a GIS environment

This study sought to use several factor criteria and constraint criteria to determine a suitable landfill site for the disposal of municipal solid waste. This was necessary because growth in population as well as rise in the quantity of municipal solid waste generated has made it difficult to locate appropriate site for waste disposal in most urban areas. Additionally, siting of landfill site has huge social and environmental concerns which must be must carefully considered.  Geographical Information System (GIS), Fuzzy Logic and Multi-criteria Evaluation (MCE) were applied in order to display and rank candidate sites. The analysis was limited to criteria that were selected and relevant to the area under investigation. The results obtained provide clear areas for landfill sites in the study area and finally arrives at suitable areas. 

(iii) 2015: Modelling of Malaria Risk Areas in Ghana by using Environmental and Anthropogenic Variables – A Spatial Multi-Criteria Approach

In this research, GIS and multi-criteria decision analysis were implemented to produce a predictive model of malaria using eight risk factors ranging from environmental to anthropogenic.  Each of the risk factors was classified into three classes of malaria risk according to how it impacts malaria prevalence. The classified risk factors were
finally overlaid through the use of weighted overlay after weights were determined from them using the Analytical Hierarchy Process (AHP). The risk map created can serve not only as a predictive tool, but can be used to obtain a comprehensive understanding of the dynamics of malaria.

(iv) 2014: Where are the Poor? Mapping Out A GIS-Multidimensional Non-Monetary Poverty Index Approach for Ghana

This research mapped out poverty endemic areas in Ghana by displaying the spatial dimensions of poverty and identifying the poverty pockets across the country adopting a Multi-dimensional (Non-Monetary) Poverty Index approach. Ten indicators which were categories under three dimensions were used. Results of the study showed that across Ghana, a considerable percentage of households are deprived in a number of non-monetary poverty indicators. Analysis of these indicators revealed wide disparities by region.

(v)   2012 - 2013:  Urban Expansion and Its Effect on Surface Temperature in the Sekondi-Takoradi Metropolis Using a Remote Sensing-GIS Approach

This research investigated the urban expansion that has taken place in the Sekondi-Takoradi Metropolis and assessed the effect of the urban expansion on surface temperature. Several remote sensing techniques were used to carry out land-use-land-cover change detection using two multi-temporal Landsat images of the years 1991 and 2008. The integrated use of remote sensing and GIS was subsequently employed to analyse the effect of urban expansion on surface temperature. The results showed that there has been significant urban growth in the study area with an annual rate of change of land cover of 4.06% and an annual rate of increase in urban/built-up land of 4.65%. This urban development caused an increase in surface radiant temperature in the study area by 4.3oC in the urbanised areas for the 17 year period.
