Abstract:

Peri urban zones are areas capable of promoting urban and rural livelihoods and coping with the pressure and dynamics of population and land use changes. On the other hand, they constitute areas that lead to progressive degradation of the environment and collapse of institutions. This study examined the drivers of growth, characteristics and environmental challenges of the peri urban zones in Benin City, Nigeria using Ekiadolor as a case study. A sample size of 393 amounting to 30% of the total number of building stock in the area was chosen. For the survey, one household per building was selected. A random sampling approach was subsequently adopted to select any available head of household for interview. Some of the attributes investigated included occupation, family size, reasons for staying in the community, length of stay, buildings characteristics, infrastructures, road network and land related issues. The peculiar characteristics of a typical peri-urban community and its asscociated environmental problems were well amplified in Ekiadolor community. It was observed that the establishment of the College of Education and the accompanying employment opportunities was the major driver for the transformation of Ekiadolor toa peri-urban settlement. Other observed drivers include the relatively low housing rents and low cost of land in the community. The study concluded that the establishment of institutions such as universities, colleges of education and research institutes among others outside the immediate precinct of cities could trigger peri – urbanization and therefore recommends that adequate provision should be made inanticipation of the envisaged challenges that are associated with such development. The study further advocated for the creation of a specialized unit to plan and coordinate such settlements. It finally calls for a synergy between the peri – urban communities and the main cities through progressive integration.

Abstract:

Socioeconomic characteristics of the people are indicators of their quality of life. Likewise, societies havetraditional views and taboos about sanitation in general and faeces in particular. The impacts of poorsanitation and hygiene cost the Nigerian economy about 445 billion naira annually. In recent years,urbanization has phenomenally increased in developing countries, making urban areas to experience severe environmental contamination. Inadequate funding, implementation of inappropriate technologies and low prioritization were the factors bedevilling sanitation progress in Nigeria. This study examines the effects of socioeconomic characteristics on the choice of sanitation facilities among households in a medium-sized city of Akure, Nigeria. A sample size of 783 was randomly taken from the study area. The outcome of the study reveals that all the socioeconomic factors except gender of household significantly affect the type of sanitation facilities used by households in the city. Planners and engineers working on sanitation projects should understand these socioeconomic and cultural factors, and utilize them for the benefit of good sanitation provision. It is recommended that advocacy should be used to inform residents of the metropolis on the health and hygiene implications of not installing toilet facilities.

Abstract:

Ancient city centres are characterised by inadequately planned/unplanned land use and unsecured tenure system, leading overtime to the development of different forms and grades of slum in and around urban core area. This research studied the slum in the urban core of Akure, Nigeria deploying tools of Geographic Information System for comprehensive analysis of slum peculiarity for guiding action. Descriptive and analytical methods based on field survey and extraction of information from satellite images were utilized. The study examined the existing situation in the study area in terms of its housing system, conditions of infrastructure, socio-economic status of respondents and adequacy of livelihood with respect to slum indicators as defined by UN-Habitat (2003). The study revealed specific areas of higher degree of slum conditions and a representation of level of changes in land uses. Another finding shows high rate of conversion, mainly from residential land uses to other uses as the major characteristic of land use changes in the area. Poverty has constituted a dominant factor for continued existence of slum conditions due to paucity of employment opportunities. The study further discovered diverse manifestations of slums within a locality attributed to factors such as strong family linkages, structure of property ownership and high level of economic dependency. Economic empowerment through aids and supports for Small Medium Enterprises (SMEs), development of market network strategy for Akure and development of a comprehensive land use plan that would ensure sustainable growth of the city core area are canvassed.

Abstract:

This research attempts to bridge the gap between the old and modern fashion of keeping and storing criminal data by investigating the level and spatial analysis of crime occurrence in Akure, Nigeria with a view to promoting security in the city. The responses obtained from the administered copies of the questionnaire were coded and entered into Microsoft Excel 2013 for generating spatial database and exported to Statistical Package for Social Science (SPSS) version 17 for statistical analysis. The crime data were analyzed using spatial analysis technique in ArcGIS 10, Global Mapper 13 and CrimeStat III. Overlaysoperations were carried out to evolve crime maps. GPS Garmin 76 was employed to obtain co-ordinates of major landmarks in the area, which comprise police stations, banks, markets, liquor stores, and places of worship among others. These were subsequently registered on the base map. The information extracted from the analyzed responses from the questionnaire and crime data were geocoded to the administered points using ArcGIS 10 for better and advanced spatial analysis, and also for hotspot and black spotanalysis using Geostatistical Analyst. The study found that the main road network that traverses Akure Metropolis, provides easy access and exit to criminals, and constitutes a dominant axis of crime events as facilities located along the road usually experience armed robbery attack or burglary. Again, crime hotspots are more prevalent in the city core. In view of the efficacy of GIS technique as a tool for detecting crime pattern, occurrence and prediction, the study advocates the development of all inclusive crime database system and training of security agents in the use of information technology to improve intelligence gathering capabilities in a bid to combat crimes in Akure metropolis in particular and Nigeria in general.

Abstract:

The use of satellite imageries and spatial analysis techniques have not been comprehensively explored and exploited in capturing baseline information for monitoring of ecologically fragile areas in most developing countries including Nigeria. This study used Landsat imageries of Akure 1986, 2002 and 2011, and topographical map, DEM, GPS points, mean annual rainfall data and structured questionnaire. Image classification was performed using supervised classification technique to capture the urban land use change over the study period. The wetlands were buffered to the radius of 200m to select the target population for questionnaire administration using ArcGIS 9.3. The responses obtained were analyzed using SPSS 17.0. DEM was subjected to spatial analysis using spatial analyst extension of the ArcGIS 9.3 and Global Mapper 13 to identify the watersheds, generate flow direction, flow accumulation and to generate the basin levels. The mean annual rainfall data, drainage basin data and elevation data were integratedand reclassified. These data were subjected to multi-criteria analysis and map overlay operation to generate flood vulnerability index map. The finding observed that area with high vulnerability to flooding occurred along the streams or river channels flowing from the eastern region of the study area towards the northwest region where physical planning standards especially on setbacks were compromised.

Abstract:

In recent times, it has been proofed that industrial revolution, urbanization, inadequate provision of facilities,poor urban management and poverty were the determinant of environmental condition of city dwellers. In thispaper, the sanitary condition of the environment of residents of Ijora Badia was investigated. Some of thesanitary conditions data involving sources of drinking water, sources of cooking, method of waste disposal, typesof toilet facility, drainage system and road conditions were collected through questionnaires, personal interview,direct observation and focus group discussion. The research population was based on the total number of existingbuildings from which the total numbers of household head were determined and 5% of the total household headpopulation was taken for the interview. Findings reveal that 65.5% of the residence sources of drinking water isthrough water vendor which has aggravated the water borne diseases, 93.1% of residence sources of cooking isstove which cause respiratory disease among the households. The paper suggests among other things that allstakeholders in the built environment should see to the welfare and provision of environmental facilities in orderto make life comfortable and functional for the slum dwellers.

Year Published:
 2014
Abstract:

Herbal Medicine plants are critically under serious threat due to anthropogenic activities in the fragile forest ecosystems in Nigeria. The study therefore examines the herbal medicine plants spatial distribution, change pattern and projects future changes to identify conservation priority areas. Landsat TM 1987 and SPOT 5 2006 satellite images were used in the study. GPS was used to collect training sites sample coordinates and used for signature development in an Object–Based Image Analysis and Segmentation Classification process for Land Change modeling. Land Cover Change Modeler and GEOMOD Modeler with IDRISI were utilized in spatial analysis. The results showed that Rhizophoraceae (Rhizophora mangle, R. racemosa) Species was declining at 353.53 hectares per year between 1987 and 2006, and projected loss at 376.16 hectares from 2006 to 2025. By implication, approximately 7,147 hectares would be under the threat of loss by 2025. Also, Rauvolfia vomitoria, receded at 10.29 hectares per year between 1987 and 2006 but would decrease to a rate of 0.085 hectares from 2006 to 2025, suggesting that about 1.6 hectares would be under extinction by 2025.By implication, the herbal medicinal plants have been susceptible to a series of encroachments due to unsustainable use of the forest resources. In this case, sustainability of these species have been threatened due to unmaintained conditions or low resilience of the species to cope with changing conditions. The study advocates monitoring and controlling of activities and developments within the area, and designating the threatened areas as protected areas.

Year Published:

Abstract:

In most developing countries, availability of piped borne water is grossly inadequate. Hence, most people rely on unsafe water for domestic use that leads to high prevalence of water borne diseases. This study demonstrated the capability of GIS techniques in combining different datasets such as relief, soil, settlement pattern, land use, waste dumpsites, pH, total water hardness and microbial count to model vulnerability of residents in Ile-Ife, Nigeria to the prevalence of water borne diseases using ILWIS 3.4 and ArcGIS 9.3 versions. The study also used structured questionnaire to elicit information on the socio-economic conditions of residents. The results of the analysis showed that 74% of the households used unimproved water. Typhoid fever was the most prevalent water borne disease followed by diarrhorea. Analysis of water samples in the community revealed high counts of micro-organism and microbial growth. The pH value from the samples proved that the water is slightly acidic while the total hardness is also high. The spread of water borne disease was visualized through spatial geo-coding technique that matched theaddresses of cases to specific locations in the study area. Vulnerability of the study area to water borne disease was assessed through the use of geo-spatial operators such as overlay, union, clipping, merging and selection of attributes to spatially visualize contributing factors initiating water borne diseases in the study area. The result showed that most areas within the city centre are highly vulnerable to water borne diseases. In addition, only an inconsequential proportion of the city exhibits low vulnerability to waterborne diseases. This implies that domestic water quality in this city has been grossly compromised. The study therefore advocates for effective wastes management, provision of safe drinking water and initiation of sustainable urban renewal programme for the city.

Abstract:

The effectiveness of the mapping and assessment of Quality of Life (QoL) in the identification of problemareas and in monitoring development policies makes it a suitable method in poverty studies. In an attempt to enhance QoL as a strategy for poverty alleviation decision-making, this research has adopted the analytical tool of Geographical Information System (GIS). Twelve indicators were used to assess the QoL of Egor Local Government Area (LGA), Edo State, Nigeria. These indicators were grouped into threedifferent domains of life (social, economic and physical). Spatial autocorrelation check was performed onthe indicators to determine the spatial prediction method that was used to map each indicator. Of all theseindicators, only two were spatially auto-correlated. The two indicators were mapped using the Inverse Distance Weighting (IDW). The other indicators were mapped using the voronoi polygons. The twelve models were used to model and assess QoL with the utilization of Multi-Criteria Decision Analysis. The weights used for the combination of the various mapped indicators were given by the respondents. TheQoL model was cross-validated using leave-one-out (LOO) cross-validation method. The result showedthat the QoL of 61.53% of the geographic space of Egor LGA was below average, 17.94% was extremelypoor, and 14.55% was average, while the classes above average and excellent were not on the QoL model. In addition, the research identified priority development areas and concluded that the QoL of thepeople of Egor LGA was poor and required urgent conscious intervention by all development partners including the government.
