ABSTRACT
This study focused on the constraints to effective solid waste management in Jos-South LGA of Plateau State, Nigeria. To achieve this purpose, four research objectives were posed with one null hypothesis postulated and tested at P = 0.5 level of significance. The population of the study is 162,387 registered voters as at 2011. A sample size of four hundred (400) was determined using Yamane (1967) method of sample size determination. Proportionate sampling technique was used to determine the sample population for each ward. Twenty nine (29) staff of PEPSA were drawn using simple random sampling technique. Two set of questionnaires were used for data collection for this study. The instruments were subjected to validation by three experts. Descriptive statistics of frequencies and percentages were used to analyze the data collected and presented in tables. Principal Component Analysis was used to evaluate the constraints to effective solid waste management in Jos-south LGA; while ANOVA was used to test hypothesis at P = 0.5 level of significance. Findings from base-line studies revealed that the current solid waste management practices in Jos-south LGA are: Use of dump soil for soil enrichment, waste sorting, waste recovery, waste burning, waste storage, waste composting and waste disposal in rivers, gutters/drainages, open spaces, illegal communities, dumpsites and disposal in burnt houses. The Principal Component Analysis was used and it evaluated four component constraints for each of the Households’ and PEPSA. Household component constraints identified were institutional problems, instability in governance, and perceptions on waste laws, poor accessibility and utility; while PEPSA component constraints are: management and evacuation problems, funding problems, crisis problems and administrative problems respectively. Base on the findings and conclusion of this work, it was recommended that there should be communities’ involvement in solid waste management, also efforts should be made to end the ongoing crisis in Jos and plans be made on how to create awareness on waste laws and the danger of inappropriate disposal of waste .

INTRODUCTION
1.1.0Background
to the study
Solid
waste can be defined as “any residue that is of no use in its current state to
the people who caused it’’ (Khattak, Khan and Ahmad, 2009). Synonyms to solid
waste are terms such as garbage, trash, refuse, and rubbish. Solid waste
management refers to the collection, transfer, treatment, recycling, resource
recovery and disposal of solid waste in urban areas (Ogwueleka, 2009). Human
activities create waste, and it is the way these wastes are handled, stored,
collected, and disposed of, that can pose risks to the environment and public
health.Themanners in which human beings dispose of their waste reflect the
level of development of that society.
During the primitive society, waste
was not a problem as land was plentiful andwastes generated were biodegradable (Ahmed
and Ali, 2004). With urbanization and industrialization, urban centres
witnessed influx of people, which brought about change in production and
consumption resulting in the production of non-biodegradable waste which
requires special management (Ajadike, 2001). In managing solid waste in
developing countries, the interest is to protect the environment and public
health, without recourse to urban development in relation to urban space to
enhance site locations for waste collection and disposal. The inability of
developing countries to plan for the high rate of solid waste generation, rapid
urbanization and high population growth in relation to the accessibility of
waste facilities have continued to bedevil recent programmes and policies for
solid waste management.
Developed countries such as United State
of America (U.S.A), United Kingdom, Switzerland and Germany have since around
1860’s strategized and planned their cities with appropriate solid waste
management systems, and technology by allowing the private sectorto manage their wastes(Ofodile, 2002, Rosenthal, 2005).
The success story of the European countries in effective solid management is
through the legal framework and programmes implementation, such as source
reduction, recycling, composting, incineration and landfills (Wilson, 1996).A massive
volume of solid waste is generated every day in the cities of developing
countries and unfortunately, solid waste management deteriorates day by day due
to inadequacies in handling the increasing rate of solid waste generation(Enajetullahand
Hashmi, 2006).
According to Pierce and Turner (1994),‘the
systems of solid waste management in most developing countries are inefficient
and ineffective’. Zurbrugg(2003) also a noted that one to two third of solid
waste generated in developing countries is not collected. The result of the
incapability of the waste management systems to effectively manage solid waste
is the deterioration of the environment via air pollution, generation of greenhouse
gases, ozone layer depletion, acid rain, vegetation depletion, water, and soil
pollution (Visvanathan, 2006). In urban areas of developing countries,
especially in the rapidly urbanizing cities of Nigeria, problems and issues of
solid waste management are of immediate importance. The uncollected solid waste
is often mixed with human excreta, clinical waste, anddumped indiscriminately
in streets and drains, resulting in flood, breeding of insects, rodents, andvectors
which spread diseases (Majumed and Karim, 2012).
Because of the increasing awareness
of the adverse effect of poor solid waste management and some positive changes
in economic circumstances, some African countries are beginning to put in
place, policies, programmes and institutions to enhance environmental
management, especially in municipal solid waste management at all levels (Olowameye,
1991). In Nigeria, the Federal Government showed its concern by establishing
Federal Environmental Protection Agency (FEPA) in 1988, which was later
upgraded in 1999 tothe Federal Ministry of Environment, thevarious States and Local
Government Areas also established their Sanitation Agencies. These moves however
shows how grave the issues of environmental problems are, particularly solid
waste management has become. The general urban scenery today exhibits the
gradual takeover of virtuallyevery available open space by refuse dumps, stagnated
drainages and gutters, smoke-laden air,hence posing serious health hazard.
Similarly,Filani and Abumere(1996)observe
that heaps of solid waste to say the least, disfigure the city image, and notonly
create an eye sore, but also pose tremendous health hazards. In Nigeria, the
most suitable and sustainable measures of solid waste management and governance
are still being debated. Theinability of the state sanitation agencies to cope
with effective management of solid waste in Nigerian cities including Jos-South
LGA continues to pose serious challenges.
This state ofconsistent inability
to effectively manage solid waste in Nigeria especially in Jos-south LGA
necessitates continued research to identify the constraints to solid waste
management. For this reason this study is being carried out to evaluate the constraints
to effective solid wastemanagement, with a view to making recommendations for
improvement.
1.1.1Statement of the Research Problem
Solid waste management is one of
the major problems facing urban centres in Nigeria. With rapid increase in
population and urbanization, solid wastes are accumulating faster than
agencies’ ability to cope with its effective management. The rate of urban
growth in Nigeria is about 3.75%, while population is increasing by about 2.47%
per annum (Nigeria Demographic report, 2014). As cities grow, land use becomes
increasingly complex and waste generated increase in volume and variety (Omuta,
1987).
Like most cities in Nigeria, Jos
city is rapidly increasing in population; from a small town of less than 10,000
people in 1930, 20,000 people in 1950, the population grew to over 600,000 in
1991 (Dung-Gwong, 2006). Besides mining, Jos was a popular recreational and
holiday town for colonial officials due to its clement weather and appealing
natural environment. This rapid growth of the city led to the creation of
Jos-South LGA in 1991 and by 2006 it had a population of 306,716 (NPC, 2006)
and this population continues to generate solid waste. In Jos-South LGA, people
tend to utilize the most expedient means of waste disposal such as burying,
dumping on land, in ditches and gutters, or drainage systems or burying in pits
and burning. These practices have resulted in a degraded urban environment and
prevalence of diseases such as cholera, diarrhea, and malaria as reported by
(PLMH, 2009).This has serious implications for the economy and livelihood
realities of the teeming population (Okafor, 2011).
Conscious of the above health implication, the
government of Plateau State has made deliberate efforts to rid Jos city of
indiscriminate dumping of solid waste. In 1976, Jos-Metropolitan Development
Board (JMDB) was created to oversee urban development and city sanitation,but the
Board could not achieve its goal on sanitation, which resulted in the creation
of Plateau Environmental Protection and Sanitation Agency (PEPSA) in 1991 to
manage waste in the city. Yet, the desire for effective management of solid
wastes was again not realized. Consequently, there was a declaration of the
state of emergency on sanitation in 2008 whereby task force on sanitation was
inaugurated to supervise the activities of PEPSA and report directly to the
Deputy Governor.Gyang (2008) and Moses (2010) report that despite all these
efforts, the city is still littered with indiscriminate dumping of solid waste.
Owing to the consistent inability to effectively manage solid waste in the area,
it has become necessary to verify and identify the constraints militating
against it
AlthoughAgunwamba (1998) identifies
some problems militating against solid waste management generally such as Lack
of planning, shortage of technical man power, finance, equipment, policies, and
enforcement of the law; Imam, Mohamed, Wilson and Cheesman (2008) on the other
hand, recognized public behaviours as the problem which affects all the stages
of solid waste management such as waste storage, collection, waste segregation,
waste recycling and disposal. But these do not appear to adequately account for
the parlous state of solid waste management in Jos-South LGA of Plateau State,
because of its peculiarity in geography and administration.
Available literature in Nigeria shows that
most attention has been focused on problems of solid waste management on
specific sectors such as: attitude, governance, collection, and disposal
(Ezeashi, 2007; Nzeadibe, Ayadiuno and Akukwe, 2009; Onah, 2010 and Moses,
2010). These researchers studied only topical aspects of solid waste management
and evaluated its problems. As such, the determination of the problems of solid
waste management using a combination of variables from the different aspects
has been largely ignored, particularly in a politically volatile environment.It
is against this gap in research and the persistent inability to effectively
manage solid waste in the area that this study is being carried out to examine
the constraints to effective solid waste management generally in Jos-South LGA,
with a view to making recommendations for improvement.
