Impact of Residential Land Use Change on Intra Urban Road Network of Akure, Nigeria (Published)

Abstract: The utilization of different land uses in different locations generates the demand for transport, where system and supply of transport enable the distribution of different land uses in different locations. Therefore, one can simply argue that urban and spatial planners, transport planners, highway engineers, public transport and logistics operators, retailers and developers should all come together to create new strategies and policies on the logic of land use management, transport geography, accessibility, and implied division of labors.  This study investigated the impact of residential land use change on intra urban road network of Akure, a medium size city with moderate population in southwestern Nigeria. Four major intra urban roads in the city center were considered in this research and a total of 150 houses and residents within 200m distance from the roads which amounted to 5% of the buildings within the study area were sampled. Information, relating to road network, condition of road, level of land use conversion among others, was gotten with Geographic Information System (GIS), questionnaire, personal observation and interview. It was found out that, most residential land use along intra urban roads in the city center had been converted to commercial land use either totally or partially. The study affirmed that, residential land use change has both physical and socio economic impacts on road network development and the environment. It was therefore recommended that, proper land use planning, establishment of a commercial center to cater for the city’s commercial needs and the preparation and implementation of a transportation master plan will reduce the problems observed. This will ensure adequate intra urban road management as well as sustainable urban development in Nigeria.

Structure of Road Network Connectivity in the Benue Basin of Nigeria (Published)

The structure of road network connectivity in any region can either promote or reduce agricultural production, market opportunities, cultural and social interactions as well as businesses and employment opportunities. This study evaluates road network connectivity in the Benue Basin of Nigeria. Data on the existing road network including type and conditions, density and length of the roads in the study area were extracted from existing road map of Nigeria, and satellite imagery of the Benue basin. The data was analysed using different methods of network connectivity analysis including beta index, alpha and gamma indices. The findings reveal four types of roads network in the basin which are grouped into three categories namely: federal highways (trunk A), state government roads (trunk B) and local government and community roads (trunk C) which are in various state of deplorable conditions. The result of connectivity analysis reveals a beta index (β) of 0.98 for the basin, alpha index of -0.05, gamma index of 0.2 which indicates that Benue basin has poor road network connectivity. A comparative analysis of road network connectivity among the five states that fall within the basin shows variation among them with Benue and Taraba states having a better connectivity than others in the region. Based on the findings, the study noted that provision of effective roads network connectivity is fundamentally important to the development and well-being of the inhabitants of the Benue basin. The current road network connectivity of the basin needs urgent attentions to reposition the region for rapid socio-economic development. The study recommends funding of road infrastructure particularly building new roads and rehabilitating the existing ones in the region by it policy makers/stakeholders considering the fact that transport is the lifeline of the economy and social interactions.

Effects of Road Networks and Human Population Density on the Risk of Dog Bite Incidents and Rabies in Nigeria (Published)

Despite efforts made to curb its spread, occurrence of rabies has continued to persist among domestic dogs in Africa. In this study we report the results of an exploratory spatial analysis and a cross-sectional study of effects of road networks and human population density on the prevalence of dog bites and rabies in Nigeria. A total of 577 dog bite cases from 17 locations, with their affected 55 administrative areas (2015-2019), were investigated. Logistic regression models were fit to the data and odds ratios at 95% confidence intervals were estimated. There is evidence of statistical relationship between increasing number of standard roadways and an increased prevalence of dog bite and rabies. Standard roadways were significantly associated with prevalence of dog bite incidents in Nigeria.  Availability of good access roads either way may contribute to the persistence of rabies in Nigeria due to massive movements of people and dogs in addition to poor attitude of dog owners towards vaccination of their dogs; or poor access to Veterinary care.
