Abstract
This paper examines the differential in the metropolitanisation of Lagos peri-urban settlements and the policy implication on locational quality of the emerging settlements. Two case studies of Ibeju-Lekki and Ikorodu were selected to represent the peri-urban settlements outside Lagos metropolitan regions. Using purposive sampling, thirty four settlements were selected which comprise sixteen and eighteen in Ibeju-Lekki and Ikorodu respectively. Data was sourced primarily through administration of 370 and 384 questionnaires to household heads in the selected settlements in Ibeju-Lekki and Ikorodu. Secondary data was sourced by conversion of analogue spatial images, the land use maps and satellite images of the study area to digital format. Spatial images from 1980 through 2016 were acquired for this study. Acquired satellite images from Google Earth archive were brought into ArcGIS environment for geo-referencing. Quantitative data was analysed using descriptive statistics while qualitative data was analysed using time series and satellite image analysis. Findings show a differential in transformation of the two cases due to varying demographic characteristics of residents, the locational convenience, level of linkages and the regional government housing policy. It is recommended that the regional planning should create a balance between the pace of development and infrastructural provision in the peri-urban to limit the disparity in development in Lagos peri-urban settlements.
Highlights
There is an evidential differential in the extent and causes of metropolitanisation of Lagos peri-urban due to many factors which include government policy on land use, accessibility to services, linkages to the metropolitan region, the socio-demography and availability and affordability of housing for the low income migrants
It is a global phenomenon that spatial areas in the periphery of metropolitan urbanised regions usually experience expansion due to direct impact of population growth and housing challenges in the urban areas
The spatial expansion of peri-urban settlements is a direct encroachment into areas originally marked for agricultural land use
Summary
There is an evidential differential in the extent and causes of metropolitanisation of Lagos peri-urban due to many factors which include government policy on land use, accessibility to services, linkages to the metropolitan region, the socio-demography and availability and affordability of housing for the low income migrants. Metropolitanisation of urban fringes in Lagos state is facilitated by many actors often with conflicting interest as seen in other developing countries (Lawanson, Yadua, & Salako, 2012). Though few research works have been carried out on land use conversion in Lagos peri-urban, the underlying causes of the differentials in extent and pattern of development is yet to be investigated. This study seeks to examine the differentials in metropolitanisation of Lagos peri-urban settlements by assessing the causes, extent, actors and policy implication of the peri-urbanisation process in Lagos metropolitan peripheral
