Abstract
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.
