    ASSESSMENT OF GREEN SPACE DEVELOPMENT IN IBADAN METROPOLIS, NIGERIA
    (The Confucius Institute, University of Cape Coast, Cape Coast, 2019-10) Raheem, W.M.; Adeboyejo, A.T.; Abolade, O.
    Green spaces in cities of developing countries are faced with severe pressure from human activities, particularly uncontrolled pace of urbanization and residential developments, thereby leading to loss of the benefits they render. However, there is a dearth of empirical studies on its assessment particularly in some cities; hence, this study assesses the green space development about the urban population of Ibadan metropolis, Nigeria. Green space area of Ibadan metropolis in m2 was computed from satellite imageries obtained from United States Geological Survey for the years 2000, 2005, 2010, and 2015. The population of the metropolis was also obtained from the National Population Commission (1991 and 2006), with projections made for the corresponding years. The green space per capita was estimated and compared with international minimum standards. Pearson Product Moment Correlation was used to test the relationship between green space per capita and time while charts were used to present the results. Findings revealed that the green space per capita of 0.73m2 for Ibadan was below both the United Nations (30m2 ) and World Health Organization (9m2 ) minimum standards. The relationship between green space per capita and time also showed a negative correlation with r = - 0.493. The projected green space availability shows that, by the year 2045, given the ongoing processes, there will be zero green space per capita. The study, therefore, recommends the use of master plan, building plan approval, and development control mechanisms among others to ensure compliance with green space coverage in new developments within the metropolis.

    Assessment of Protected Green Space of Eleyele Dam, Ibadan
    (School of Environmental Technology, Federal University of Technology, Minna, 2021) Raheem, W.M.; Adeboyejo, A.T.; Abolade, O.
    Relationship has been established between urban green space depletion and urbanization in the developing countries, just as poverty and destruction of green space have also been found to be correlated. Green space particularly in the government reserved areas have also suffered depletion from urban dwellers in form of encroachment and over harvesting. These have resulted in the abuse of green areas in cities, thereby denying the city’s people the invaluable benefits expected from such green areas. This study assessed the protected green space of Eleyele dam of Ibadan, Oyo state Nigeria, with a view to suggesting sustainable policy guidelines. Two hundred and eleven questionnaires were administered on all the occupants using the space, to solicit information on their socioeconomic characteristics, status of tenure and security of the green space occupied among others. While Likert scale was used in analysing the frequency of harvested products, Pearson Product Moment Correlation was employed in testing the relationship between length of stay of occupants and size of land occupied. Results showed that firewood and herb products were more harvested constituting more than two-third (72%) of the entire harvest. It was also revealed that except gardening, all other activities in the plantation constitute danger to the green space. The result of Pearson Product Moment Correlation r = 0.61 showed a positive correlation between length of stay of occupants and size of land occupied. By implication, the protected green space is under a severe threat if the encroachment continues unabated. The study concluded by recommending that further granting of approval on the land be stalled, non-compatible activities that could further lead to depletion of the green space should be discouraged and there should be thorough monitoring of the activities of people within the area

    Urban Greening and City Sustainability in Ibadan Metropolis, Nigeria
    (Department of Geography and Environmental Studies, Bahir Dar University, Ethiopea, 2016) Raheem, W.M.; Adeboyejo, A.T.
    The pace of urbanization, especially with cities in the developing world, has negatively influenced green areas and, as a consequence, threatened the several benefits provided by vegetation cover. Green areas provide shade, evaporative cooling, rainwater interception, and storage and infiltration functions, with impervious built surfaces. Consequently, the ecosystem services provided by urban green spaces are often overlooked and undervalued. The study uses primary data, which were obtained through a random and systematic sampling of three hundred and forty four respondents. Variables used in the analysis include socio-economic characteristics of the respondents, the types of urban green space, benefits of urban green space to the respondents as well as the management strategies involved. Data collected were analysed using descriptive and inferential statistics. ANOVE result shows that there is significant variation in the types of urban greening with F-value of 4.920, 3.673, 4.822; and p-value of 0.001, 0.006 and 0.000 for road greening, residential greening and institutional greening respectively. Besides, the study reveals that most of the areas in the metropolis are more of concrete than open space with 41.8% covered up with 75% concrete, 18.4% with 50% coverage and only 9.4% is less than 25% concrete coverage. The study therefore recommends the use of land development plan and the use of planning approval strategies among others, to ensure adequate room for urban green space in the metropolis.
