Abstract

A new Ministry of Physical Planning and Urban Development has just been established in Ondo State, Nigeria. The development was expected to herald efficient and sustainable physical planning. To maximize the opportunities offered by this innovative development, some conditions are desirable. This paper therefore examined the problems confronting physical planning in the State and proffer appropriate solutions to unravel them with the intention of optimizing the gains arising from this innovation. The study involved a survey of physical planning mechanisms and agencies of governments responsible for physical planning in Ondo State. It investigated the evolution of physical planning in the state. Other variables examined include: human and financial capacity available for physical planning, development control process, master planning, inventory of project vehicles and equipment among others. The problems that were identified include lack of urban development policy, ineffective development control, inadequate/absence of capacity in appropriate discipline, dearth of spatial information and data and absence of master plan to guide the development of settlements in the State. The paper therefore canvassed for immediate evolvement of urban development policy coupled with series of legislations and regulations that would facilitate development control. Other recommendations include capacity building in relevant discipline, recruitment of staff with contemporary knowledge in urban planning, acquisition of spatial information and data for planning purposes and the immediate development of master plans for major settlements in the State.

Abstract

Abstract In most developing countries, it has been recognized that conventional water utilities have fallen short in providing adequate water services to populations. Festac Town, Lagos, Nigeria is a typical community that is presently not being serviced by such water utilities due to the inability of the Water Supply Agency (WSA) in supplying water to the area. Households therefore seek other alternative sources including water vending. This paper examined the role of water vending in household water supply delivery in this community. It identified the sources of water supply by the vendors, assessed their level of patronage among households and identified the problems associated with their operations. For the study, a total number of 1,139 and 57 households and vendors were selected by simple random sampling respectively. The result showed that there are two main categories of water vending namely; formal and informal vendors. All formal vendors obtain their supplies from improved sources while most informal vendors obtain theirs from unimproved sources. Majority of the households consider vended water as a coping strategy since they are aware of the safety implications. Therefore, most households are willing to pay for water services. The paper canvassed the need for government to recognize the role of water vending in water delivery. It advocated for a secondary level of supply mechanism among vendors in a bid to ensure quality water supply. The paper concluded that the most sustainable strategy would be to resuscitate the moribund piped water supply system earlier initiated by the WSA.

Abstract

Problem statement: The efficiency and effectiveness of domestic water sources are often gauged by availability, accessibility and adequacy. This study examined various variables that could be harnessed in measuring these parameters with respect to water supply in Ado-Ekiti, Nigeria. Approach: The purpose of this study is to investigate the various attributes of domestic water sources in Ado-Ekiti, Nigeria. Three residential zones were identified in the city. They included the urban core, transitional zone and urban periphery. A sample size of 1,200 amounting to 4.0% of the total number of households in Ado-Ekiti, was chosen. Specific areas referred to as Data Delineation Areas (DDAs) were identified in each zone. Based on the estimated population of each DDA, the number of households to be interviewed was estimated. In consonance with some assumptions, 600 (50.0%) questionnaires were administered in the city core while 420 (35.0%) and 180 (15.0%) questionnaires were administered in the transitional zone and urban periphery, respectively. Subsequently, systematic sampling procedure was adopted in the choice of households to be interviewed. Some of the attributes investigated included the main source of domestic water used by household, access to improved source of water, distance from improved source to residence, average time spent to fetch from main source, average number of trips per person per day, quantity of water used per person per day and attack by water-borne diseases. Results: Households in Ado-Ekiti had access to diverse sources of domestic water including wells, boreholes, streams/rivers/springs, tanker-drawn water and rainwater. However, most households (59.8%) depended on wells. Nevertheless, 84.3% had access to improved sources. Only 10.0% of these households obtained supplies from piped water while piped network is largely restricted to the city core. The research showed that distance, time, number of trips and adequacy of supplies placed limitations on access to improved source. Only 63.2% of the households in the city obtained water supplies within 1 km from their dwelling places. About 67.0% spent less than 30 min round trip to obtain water from improved sources while 61.6% made more than three (3) trips to water sources per day. Only 22.7% of the households had access to at least 40 L per person per day while 36.9% were annually afflicted with water-borne diseases such as typhoid, diarrhea and stomach ache. Conclusion: Domestic water supply system in Ado-Ekiti, Nigeria is characterized by low level of access, inadequate supplies from improved sources while these sources are usually distant away from the households.

Publication Title Citizens Willingness To Pay For Improved Sustainable Water Supply In A Medium-sized City In South Western Nigeria
Publication Authors Olajuyigbe, A.E and Fasakin, J.O
Year Published 2010
Abstract

Willingness to pay for urban services is often regarded as a means of ensuring the long term
sustainability of such services. This paper examined some factors that explain citizens’ willingness to pay for improved sustainable water supply in Ado-Ekiti, Nigeria. Such analysis is critical to the success of the
government current drive on privatization and divestment on infrastructural financing. Empirical estimates show that factors that significantly affect willingness to pay for improved sustainable w ater supply include; main source of domestic water used by household, access to improved source of w ater, distance from main source to house, average time spent to fetch from main source, adequacy of supply from main source, quantity of water used per person per day, quantity of water purchased per day, attack by water borne diseases, performance of supply from designated w ater institution and average amount spent on water during the dry season. Some policy implications of findings are discussed.

Publication Title Some Factors Impacting On Quantity Of Water Used By Households In A Rapidly Urbanizing State Capital In South Western Nigeria
Publication Authors Olajuyigbe, A.E
Year Published 2010
Abstract

A water supply is an essential requirement for all people. However, a certain minimum quantity of water per person per day is required to meet the domestic and hygiene needs of the people. This paper examined some factors that impact on the quantity of water available to households in Ado-Ekiti, Nigeria. Such analysis is critical to any attempt by government to improve domestic water supply in the city. Empirical estimates show that factors that significantly affect the quantity of water used by households include: distance from main source to house, average time spent to fetch from main source, average number of trips per person per day to main source, adequacy of supply from main source, performance of supply from designated water institution, main source of domestic water used by household, education level, profession/occupation and annual income. Some policy implications of findings are discussed.

Publication Title Sustainable Water Service Delivery: An Assessment Of A Rapidly Urbanizing City In Nigeria
Publication Authors Olajuyigbe, A.E
Year Published 2010
Abstract

In the Nigerian Federation, water supply is a state responsibility. State governments have therefore created State Water Agencies to manage and operate systems for water service delivery in all urban and semi-urban areas. Generally, these State Water Agencies have failed to effectively deliver water services to the people. In Ado-Ekiti, the Ekiti State Water Corporation is saddled with the task of meeting the water needs of the city dwellers. This paper examines some factors that explain the poor service delivery level of the Corporation. Adopting a sample size of 1,200 (4% of the total number of households in Ado-Ekiti) through random sampling technique, empirical estimates show that factors that significantly affect the performance level of this Corporation include: payment for water supply, billing system, adequacy of supply, frequency of pumping of water, notices from the Corporation in cases of system breakdown, response to leakages, adequacy of public standing pipes and appropriate location or distribution of standing pipes. The paper clamored for an evolvement of water policy for the state that would adequately address the issues emanating from the significant factors affecting the Corporation performance.

Publication Title Evaluation Of Domestic Water Security In A Developing Economy - A Focus On Ado-Ekiti, Nigeria
Publication Authors Olajuyigbe, A.E
Year Published 2010
Abstract

Domestic water security could be described as the household’s regular access to adequate safe water. When these conditions are compromised, people face acute human security risks transmitted through poor health and the disruption of livelihoods. This study assesses the level of domestic water security in Ado-Ekiti, Nigeria, using two key variables: access and quality. For the study, three residential zones were identified in the city. They include: the urban core, transitional zone and urban periphery. A sample size of 1,200 amounting to 4.0% of the total number of households in AdoEkiti was chosen. Specific areas referred to as Data Delineation Areas (DDAs), were identified in each zone. Based on the estimated population of each DDA, the number of households to be interviewed was estimated. Based on some assumptions, 600 (50.0%), 420 (35.0%) and 180 (15.0%) questionnaires were administered in the city core, transitional zone and urban periphery, respectively. Subsequently, random systematic sampling procedure was adopted in the choice of households to be interviewed. For data analysis, descriptive statistics including Tables, Frequencies and Means were utilized. The results showed that, water security is in a precariously compromised condition in Ado-Ekiti. The study called for the evolvement of a well articulated water policy, spelling out strategies and targets for achieving water security in the State. Other suggestions include, among others, expansion of the existing dam, atomisation of water supply sources, involvement of private sector in water management and active community participation.

Publication Authors Olajuyigbe, A.E., Alinaitwe, P., Adegboyega, S.A., and Salubi, E
Year Published 2012
Abstract

The high prevalence of cases of waterborne diseases in most cities in Nigeria is alarming.  In these cities, there is littledocumentation about the spatial variability of the incidence of the diseases.This study adopts GIS techniques to investigate the spatial variation of waterborne diseases in Ile-Ife, Nigeria. Data for the study were acquired fromIKONOS satellite imagery and topographical map from which essential featureswere extracted using digital image processing techniques of Erdas Imagine 9.1 version.Structured questionnaire was also used to elicit information on households’socio-economic characteristics. Water samples were collected and analyzed usingstandard microbial and chemical methods. The microbial count, pH and waterhardness were interpolated using Krigging interpolation technique in ArcGIS9.3. The secondary data utilized for the study include land use data andreported cases of water borne diseases from health facilities. Geocodingtechnique of ArcGIS 9.3 was employed to match the addresses of the patientswith the cases of water borne diseases. The results showed that mostreported cases of water borne diseases were due to environmental factorsincluding poor environmental sanitation and topography. This implies that acontinuous negligence and under estimation of the role of these factors in thespatial spread of the water borne diseases may increase the vulnerability andhealth risk of the people in the area. The study recommends frequent treatmentof wells and boreholes, improved environmental sanitation and enhanced wastemanagement strategies.

Publication Title Vulnerability And Risk Analysis Of Water Borne Diseases In Ile-Ife, Nigeria
Publication Authors Olajuyigbe, A.E., Alinaitwe, P., Adegboyega, S.A., and Salubi, E
Year Published 2013
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 the
addresses 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 problem
areas 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 three
different domains of life (social, economic and physical). Spatial autocorrelation check was performed on
the indicators to determine the spatial prediction method that was used to map each indicator. Of all these
indicators, 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. The
QoL model was cross-validated using leave-one-out (LOO) cross-validation method. The result showed
that the QoL of 61.53% of the geographic space of Egor LGA was below average, 17.94% was extremely
poor, 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 the
people of Egor LGA was poor and required urgent conscious intervention by all development partners including the government.

Publication Authors OLAJUYIGBE, A.E., BALOGUN, I.A., AKINRINOLA, O.O. and EBIYEGBAGHA, A.B.
Year Published 2013
Abstract

Climate change is posing threat to existence of life. Many developing nations including
Nigeria lack the necessary coping capability for the impact of climate change. It has therefore
become necessary to integrate climate change concerns into spatial planning. This research
aimed at assessing the human settlement adaptation strategies arising from climate change impacts
in Asaba, Nigeria. The town was delineated into four clusters - Umuagu, Umuezeh, Ogbeumuata
and Umuonaji. A sample size of 900 amounting to 4.2% of the total number of households was
chosen. Using systematic random sampling procedure, respondents were selected in proportionate
to the established household population in the various clusters. Data collected include level of
awareness about climate change, household vulnerability to climate change impact and adaptation
measures adopted by households. These data were analyzed and results presented with descriptive
statistics including Tables, Charts and Figures. Identified adaptation strategies in the community
include land filling, sinking of boreholes, adoption of aquaculture, increased in Damp Proof Course
(DPC) level and tree planting to reduce the effect of urban heat island. The paper concluded that
most of the adaptation strategies that were put in place are effective as they have relatively reduced
the impacts of climate change in the study area. The research however canvassed for the establishment
of climate change information systems that will facilitate robust awareness and promote
early warning systems. Other recommendations include provision of intensive training on
sustainable adaptive climate change strategies, identification of vulnerability hot spots and adop-
tion of community penetrative public enlightenment on climate change phenomenon.

Abstract

Aims: Road accidents have impacted adversely on the socio-economic development of cities in developing countries. Abuja, the administrative headquarters of Nigeria is known for regular occurrences of such accidents. This study attempted to identify factors responsible for these accidents and assessed their pattern with a view to mapping the black spots in the city using GIS techniques.
Study design: The study was an attempt to investigate the various accident spots in Abuja, Nigeria in a bid to present a platform for proffering plausible solutions to the rampant road accidents in the city.
Place and Duration of Study: Abuja, Nigeria, between January 2011 to July 2011.
Methodology: Road accidents data from road users, National Union of Road Transport Workers (NURTW) and Federal Road Safety Corps (FRSC) were acquired using structured questionnaire. Also, secondary data including topographical map, quick bird image, accident records between 2009 and 2011, and GPS points of areas prone to road accidents were plotted on the Abuja base map. These data were integrated and analyzed using spatial analysis tools of AcrGIS 9.3. Table data were also imported into ArcGIS database. Overlay function and query operation were performed to determine the accident hotspots based on the frequency of road accidents and their spatio-temporal trend.
Results: Findings showed that Wuse maintained the highest black spots while Asokoro experienced the least. It was observed that accidents are caused by road, vehicle, driver and environmental factors.
Conclusion: The study recommends provision of functional traffic lights and defining danger times of high risk locations in Abuja.

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

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.

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 2015
Abstract

Socioeconomic characteristics of the people are indicators of their quality of life. Likewise, societies have
traditional views and taboos about sanitation in general and faeces in particular. The impacts of poor
sanitation 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

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. Overlays
operations 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 spot
analysis 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 integrated
and 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

This study examines urban spatial change in land use and land cover of Ibadan Northwest Local Government Area (LGA) in Oyo State. The general patterns of land use/cover as they were recorded in remotely sensed data were analysed. Multi-date satellite imageries (Landsat ETM+ 2000, Landsat ETM+ 2014 of 30m spatial resolution respectively were obtained and used for the study. These images were enhanced, geo-referenced and classified using IDRISI software. The result of ground truthing was combined with visual image interpretation as training sites for supervised classification. To predict land use land cover change of the area in the next 7 years, CA-Markov chain analysis, a land cover prediction procedure was introduced. The results showed that the natural environments (vegetation, wetland, water bodies, forest, grassland and built-up) were being threatened, as they reduced continually in the area extent over time and space while the social environment (built up area) expanded and this may likely be the trend between 2000 and 2021 as projected. The study discovered that urbanization processes is majorly responsible for land-use/land-cover change in Ibadan North-west. In conclusion, the study advanced our frontier of knowledge on land use/cover study by providing information on the status of natural and social environment in Ibadan North-west, between 2000 and 2021 using remotely sensed images and Geographic Information Systems (GIS) technology.

Publication Title Drivers And Traits Of Peri–Urbanization In Benin City, Nigeria: A Focus On Ekiadolor Community
Publication Authors Ayo Olajuyigbe
Year Published 2016
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 to
a 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 in
anticipation 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.
