WASTE DISPOSAL IN OSOGBO METROPOLIS, A MODERN SYSTEM OF GARBAGE DUMPING
CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF STUDY
Solid Waste Management has remained an intractable environmental problem in Nigeria. This issue has shown in form of loads of
indiscriminately disposed heaps of uncovered waste and illegal dumpsites along major roads and at street corners in cities and urban areas.
It has multiplied by the speedy urbanization and population increase which led to the generation of enormous quantities of solid waste
which are often discarded by open dumping. Rush broke (2013) describes open dumping of municipal solid waste as a primitive stage of
waste disposal, practiced by three fourths of countries and territories round the world. Uncovered dumps are the main causes of
environmental pollution and public health concerns in many developing countries including Nigeria. These open waste dumps usually
contain a mixture of general waste and toxic, infectious or radioactive wastes and are susceptible to burning and exposure to scavengers.
According to Babanawo (2013), waste generation is greatly influenced by geographic and physical factors. The factors are: location
geographically, year, usage of kitchen waste food grinders, waste collection frequency and the characteristics of the service area. There are
a number of major risks and impacts of the dumpsites on the environment. For example, open burning leading to air pollution , as a result
of emission of greenhouse gases such as methane and carbon dioxide; the air emissions generated as a result of decay of waste may
contaminate air, surface and groundwater sources; fire outbreaks and explosions causes risks to the public health as well. The release of
greenhouse gases, rodents and fly infestation and irritating eects are among health and environmental impacts of improper solid waste
management. Disbursing of wastes by wind and scavenging by birds, animals and waste pickers creates aesthetic nuisance. Bad odor
emanating due to the degradation of solid waste in the dumpsites has nuisance effect and reduces economic and social values in the
locality. The solid waste in many dumpsites is directly increasing global concern over public health impacts leads to environmental
pollution, in particular, the environmental quality and human health risks associated with the waste dumps. About a quarter of diseases
facing mankind today occur to prolonged exposure to environmental pollution according to the World Health Organization estimation.
However, there seems to be no clearly stated guidelines at the national or state levels on how to deal with these dumpsites in a sustainable
manner, precisely in the developing countries where ironically the burden of environmental pollution seems to be highest. Land filing has
been the most common method of solid waste disposal generated by different communities for many years (Komils et al., 2013). Three
types of landfills are an integral part of most solid waste systems. They include the open dump, the semi-controlled landfill, and the
sanitary landfill. The majority of urban centers in the developing world (including Africa) use open dumping as their principal disposal
method (Rush brook, 2013). This showcases a variety of problems as the open dumps expose human beings, animals and the environment
to serious risks. Majority of local authorities happens not to pay adequate attention to the solid waste dumps, because they do not know
better systems and what happens there is out of their sights. It is important to operate them efficiently as possible so as to mitigate any
health and environmental disasters that may result from the neglect of waste dumps. Provision of adequate sanitation and water facilities
in urban areas is an important means of ensuring health and well-being of the people living in cities, as well as protection of the
environment. Ayoola et al (2012) wrote on Assessment of Housing Sanitation and Waste Management Practices in the Residential Core Areas
of Oshogbo, Osun State Nigeria. They noted that good environmental condition and livability of these settlements are affected partly by
inadequate of infrastructural facilities which is a major factor that determines the level of sanitation and that the government should ensure
that existing laws and regulations guiding environmental sanitation and health be reviewed and also enforced with stiffer actions in order to
make it more effective. Also so, they recommended that in order to avoid or minimize waste dumps, some strategies such as more frequent
collection of waste could be implemented, while continuous educational campaigns informing the disadvantages of a dirty area is also an
important way of motivating people to keep the community clean and this may reduce the dumping problem.
1.2 STATEMENT OF PROBLEM
In Nigeria, Waste disposal remains a contentious issue, and with no end in sight, refuse is dumped on roadways, pedestrian work ways or
even dropped in drainage or streams and rivers. The situation is more alarming during the rainy season as water no longer flows freely
along the gutters; it remains stagnant, creating the conditions for mosquito to breed and also the spread of vector borne diseases like
malaria. The rapid rate of urbanization witnessed in most Nigeria cities contributed to high increase in waste generation which has
outgrown the capacity to evacuate them. Onibokun and Kumuyi (2013) confirm that whenever urbanization gets out of control, it poses a
big challenge to urban management and government, with waste management inclusive. The problem of urban waste management in
Nigeria persists due to many factors which include the rapid rate of uncontrolled and unplanned urbanization of majority of our states. In
Osun state, where Oshogbo is situated several attempts have been made to improve on proper solid waste management and sanitation in
the State. These efforts consist of the mandatory sanitation which takes the last Saturdays of every month. Acquisition of the waste
disposing vehicles by the government which will be going through the state to collect household waste, construction of boreholes by
government, organizations and individuals, channelization of major rivers among others. Despite these efforts, the problem of waste
management still exists.
1.3 AIMS OF THE STUDY
The major aim of the study is to examine waste disposal in Oshogbo; a modern system of garbage disposal. Other specific objectives of the
study include;
To examine the sources of solid waste in Oshogbo metropolis;To examine the stages involved in effective waste disposalTo examine the effect of solid waste disposal on quality of life;To examine the challenges of effective waste disposal in Oshogbo metropolisTo examine modern systems of waste disposal in Oshogbo metropolis.To examine the solutions to improper waste disposal in Oshogbo metropolis
1.4. RESEARCH QUESTIONS
What are the sources of solid waste in Oshogbo metropolis?What are the stages involved in effective waste disposal?What are the effects of solid waste disposal on quality of life?What are the challenges of effective waste disposal in Oshogbo metropolis?What are the modern systems of waste disposal in Oshogbo metropolis?What are the solutions to improper waste disposal in Oshogbo metropolis?
RESEARCH HYPOTHESIS
Hypothesis 1
H0: solid waste disposal has no significant effect of on quality of life of residents of Oshogbo metropolis.
H1: solid waste disposal has a significant effect of on quality of life of residents of Oshogbo metropolis.
1.6 SIGNIFICANCE OF THE STUDY
The study would be of immense benefit towards the elaborating of waste management, the implementation of waste sanitation equipment,
use of appropriate technologies and efficient facilities suitable for environmental protection to be introduced and utilized for the benefit of
all in the waste-polluted environs in Nigeria. This study would also be of immense benefit to students, researchers and scholars who are
interested in developing further studies on the subject matter.
SCOPE AND LIMITATION OF THE STUDY
The study is restricted to waste disposal in Oshogbo metropolis; a modern system of garbage dumping
LIMITATION OF THE STUDY
Financial constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or
information and in the process of data collection (internet, questionnaire and interview)
Time constraint: The researcher will simultaneously engage in this study with other academic work. This consequently will cut down on
the time devoted for the research work.
