Like many developing countries over the decade, Nigeria has experienced rapid urbanization associated with numerous problems such as, among others, improper waste management practices, building development regulations and standards contraventions, environmental pollution, overcrowding, and flooding. In light of the foregoing, this article examines the use and effectiveness of development control measures in addressing flood vulnerability in Suleja, Nigeria. In carrying out this study, buildings vulnerable to flooding were identified and factors influencing their vulnerability as well as the implications of non-adherence to development control measures were also determined. As part of this study, a total of 278 questionnaires were administered to adult residents of the study area, using multi-stage sampling techniques. A quick bird’s eye image of 15-meter resolution was used to identify and map out the buildings in the area considered vulnerable to flooding, using a 15-meter setback from the river banks. The study reveals that 799 buildings were built in contravention of building development standards and regulations in Suleja, while indiscriminate solid waste disposal methods were found to be strong factors influencing vulnerability to flooding in the area. The study also revealed that 47% of drainages in Suleja are blocked with indiscriminately disposed solid waste materials. The study recommends that an improved solid waste management system for Suleja be put in place to stem the imminent outbreak of diseases associated with poor environmental management and that development control measures be strictly enforced by the Niger State Urban Development Board.

Solid waste management has been part of human activities right from time. Effort by the Oyo State Government in managing the collection and disposal of waste generated in Ibadan is seen in the provision of Skip bins at specific locations across the city. However, despite the provisions made by the government, an emerging trend is the dumping of refuse along the median of some major and collector roads in the city. This study aims at emphasizing a planning framework for the location of solid waste disposal infrastructure (Skip bins) through the adoption of planning standard. The aim of this study was achieved by identifying the existing skip bins within Ibadan North. More so, a spatial analysis of skip bins and resident's access to solid waste facilities within Ibadan North was deduced. Geospatial techniques were used for this study; data from primary and secondary source were also used to corroborate the geospatial findings. The study identified a total of 37 skip bins located within Ibadan North Local Government, serving the entire Ibadan North. Spatial analysis of the skip bins revealed a clustered distribution which is consequential to indiscriminate solid waste disposal within Ibadan North. The study recommends adequate provision and location of skip bins to contribute to a cleaner and safer environment and a design blue print for Ibadan North was proposed.Keywords: GIS, Median, Nearest Neighbour Analysis (NNA), Skip Bins

Urban poverty coupled with housing shortages have contributed to the proliferation of informal settlements and slums. This is one of the complex problems arising out of urbanization and which is piling pressure on urban authorities to use unorthodox methods (such as forced evictions) to ameliorate the situation. This paper revisits the use of forced migration in Badia East Community of Lagos city. Using the human security concept as a framework for analysis, the paper chronicles how urban forced migration is used as a tool to relocate the vulnerable urban poor by urban authorities in their bid to achieve sustainable development. Critical insight into the nature of these migrations was achieved by gathering data using the mixed approach. Finding from the study revealed rampant human abuse through the use of force during the eviction process. The paper concludes by recommending that the government should use best practices, (such as adequate government-assistance) during relocations and rehousing option explored.

Efficient allocation of spaces for all activities is a pivot role of planners in human settlements development. The rapid and unplanned growth of Ibadan has limited farmers’ access to land for urban agriculture purposes, especially in the urban local government areas (LGAs). This study examined urban farmers’ access to land for farming and the activities of local planning authorities in terms of land allocation for farming in Ibadan. A structured questionnaire was administered to 244 urban farmers, while key-informant interviews were conducted with the officials of local planning authorities and departments of agriculture in the urban LGAs in Ibadan. The study revealed that the scarcity of land for farming has subjected over 30% of the respondents to practice farming on family land, while 17% farmed on available open spaces, including floodplains; land along mountain ridges; land under power lines, and institutions’ lands. The barriers to expanding urban farmland identified by farmers included finance, the unavailability of land in the urban area, neglect of farming and land tenure system. The study recommended the enactment of a planning policy for the classification and integration of agricultural land use as a recognised land use component in urban physical development and zoning plans.
