ABSTRACT
This study has
attempted to measure the impact of
agricultural output on economic growth. The study made use of secondary data
from 1970-2004 sourced from various CBN publications and with the use of the
ordinary least squares regression procedure, our estimates were determined.
The empirical analysis carried out confirmed that agriculture has contributed
positively to economic growth.
The
model employed is adopted along the Robert Solow model based.

CHAPTER ONE
INTRODUCTION
1.1 Background to the
Study
One of the important
objectives of macroeconomic policy has been the rapid economic growth of an
economy. Economic growth is defined as “the process whereby the real per capita
income of a country over a long period of time.” Economic growth is measured by
the increase in the amount of goods and services produced in a country. A
growing economy produces more goods and services in each successive time
period. Thus growth occurs when an economy’s productive capacity increases
which in turn is used to produce more goods and services. In its wider aspect,
economic growth implies raising the standard of living of the people and
reducing Inequalities of income distribution. Economic growth is a desirable
goal for a country. But there is no agreement over the annual growth rate which
an economy should attain. (Jhingan, 2000).
Generally, economists
believe in the possibility of continual growth .This belief is based on the
presumption that innovations tend to increase productive technologies of both
capital and labour over time. But there is every possibility that an economy
may not grow despite technological innovations. Production might not increase
further due to lack of demand which may retard the growth of the productive
capacity of the economy. The economy may not grow further if there is no
improvement in the quality of labour in keeping with the new technologies.
Economic growth is
usually measured in terms of an increase in real gross national product (GNP)
or gross domestic product (GDP) over time or by an increase in income per head
over time. GDP measures increase in total output to a change in population.
Thus, if total output rises higher as compared to population, then theirs an
improvement in the average living standards. Growth is desirable because it
enables the community to consume more private goods and services and the
provision of a greater quantity of social goods and services such as health,
education, etc. in this manner improving living standards. Government can also
stimulate economic growth by increasing its current spending in the economy and
through tax cuts (fiscal policy), and by increasing money supply and reducing
interest rates (monetary policy).
Principally,
there are three main determinants of economic growth, which are; the growth of
its labour force, the growth of capital stock, and technical progress.
Nigeria used to be
heavily dependent on the agricultural sector prior to the oil boom. In the
early 1950’s up to the early 1970’s before the discovery of crude oil,
agriculture was the mainstay of the economy, employing 70 per cent of the total
population. Although subsistence farming was predominant, it was a major
revenue earner for the country. In the early 1980’s, it became more apparent
that the agricultural sector could no longer perform its traditional role of
meeting domestic food requirement, raw materials for industry and started to
decline as a major foreign exchange earner through
exports due to economic , social and
political problems.
Nigeria's
soils and climate allow cultivation of a wide variety of food crops, including
cassava (of which Nigeria is the largest world producer), millet, sorghum and
maize. Agriculture is Nigeria's biggest employer of labour, accounting for
about 60 per cent of the workforce, working mainly in small-holdings using
basic tools. Together with livestock rising, it provides a third of gross
domestic product.
Growth
in agricultural output averaged 3.5 per cent over 1993-1997, higher than the
population growth rate, 4.0 per cent, 5.2 per cent, 2.9 per cent, 5.1 per cent
from 1998-2000 respectively (CBN 2000). This compares with a period of
stagnation in the first half of the 1980’s when growth averaged just 0.5 per
cent, due to low producer prices, marketing restrictions and a drought.
Agriculture picked up after the economic reforms introduced in 1986, which
included trade liberalization, dissolution of price-fixing marketing boards and
improved producer prices facilitated by devaluation of the naira. Growth in the
sector averaged 3.8 per cent in 1986-92, and there was a burst of activity in the
cash crop sector, with many farmers returning to previously abandoned fields. However,
the renewed interest was not sustained, nor did it result in increased
investment in cash crop production, mostly carried out by smallholders.
Improved food crop production contributed to a sharp fall in food imports, from
19.3 per cent of total imports in 1983 to 7.1 per cent in 1991, although this
crept back up to 13.1 per cent in 1996. Much of the increase in agricultural
output in recent years has resulted from expansion of the area under
cultivation, rather from increased productivity. The sector has been hampered
by lack of investment in improved farming technology. Over-farming of fragile
soil has worsened.
The share of
agricultural products in total exports has plummeted from over 70 per cent in
1960 to less than 2 per cent today. The decline was largely due to the
phenomenal rise of oil shipments, but also reflected the fall in the output of
products like cocoa, palm oil, rubber and groundnuts, of which Nigeria was once
a leading world producer. For example, production of cocoa, currently Nigeria's
biggest non-oil export earner, has remained around 160,000 tonnes per year
since 1995, compared with an annual average of 400,000 tonnes at its peak
before the oil boom. The government has made some effort to encourage private
investment in agriculture and agro-industries by providing incentives,
including tax breaks, finance credit and extension services, but without much
success
This area of study is quite broad and as such various
studies have been carried out in the area in general and other sub-sectors,
highlighting the relevance of the sector towards economic growth. With the
understanding been identified, many researchers, scholars have developed models
on improving and developing the agricultural sector especially in developing
countries. However the study will attempt to review available literatures
within its reach.
1.1.0 Socio-economic
and development challenges in Nigeria’s agriculture
Nigeria
is one of the largest countries in Africa, with a total geographical area of
923 768 square kilometres and an estimated population
of about 126 million (2006 estimate). It lies wholly within the tropics along
the Gulf of Guinea on the western coast of Africa. Nigeria has a highly
diversified agro ecological condition, which makes possible the production of a
wide range of agricultural products. Hence, agriculture constitutes one of the
most important sectors of the economy. The sector is particularly important in
terms of its employment generation and its contribution to gross domestic
product (GDP) and export revenue earnings. Despite Nigeria’s rich agricultural
resource endowment, however, the agricultural sector has been growing at a very
low rate. Less than 50% of the country’s cultivable agricultural land is under
cultivation. Even then, smallholder and traditional farmers who use rudimentary
production techniques, with resultant low yields, cultivate most of this land.
The smallholder farmers are constrained by many problems including those of
poor access to modern inputs and credit, poor infrastructure, inadequate access
to markets, land and environmental degradation, and inadequate research and
extension services.
Since
the collapse of the oil boom of the 1970s, there has been a dramatic increase
in the incidence and severity of poverty in Nigeria, arising in part from the
dwindling performance of the agricultural sector where a greater majority of
the poor are employed. Furthermore, poverty in Nigeria has been assuming wider
dimensions including household income poverty, food poverty/insecurity, poor
access to public services and infrastructure, unsanitary environment,
illiteracy and ignorance, insecurity of life and property, and poor governance.
In response to the dwindling performance of agriculture in the country,
governments have, over the decades, initiated numerous policies and programs
aimed at restoring the agricultural sector to its pride of place in the
economy. But, as will be evident from analyses in the study, no significant
success has been achieved due to the several persistent constraints inhibiting
the performance of the sector. From the perspective of sustainable agricultural
growth and development in Nigeria, the most fundamental constraint is the
peasant nature of the production system, with its low productivity, poor
response to technology adoption strategies, and poor returns on investment. It
is recognized that agricultural commercialization and investment are the key
strategies for promoting accelerated modernization, sustainable growth and
development and, hence, poverty reduction in the sector. However, to attract
investment into agriculture, it is imperative that those constraints inhibiting
the performance of the sector are first identified with a view to unlocking
them and creating a conducive investment climate in the sector.
The
development challenges of Nigeria’s agriculture are, therefore, those of
properly identifying and classifying the growth and development constraints of
the sector, unlocking them, and then evolving appropriate strategies for
promoting accelerated commercialization and investment in the sector such that,
in the final analysis, agriculture will become one of the most important growth
points in the economy.
In spite of the existence of a well-articulated
agricultural policy document for Nigeria since 1988, the country has never
established a systematic focus in her agricultural planning history that shows
a conscious effort to purposely prioritize her agricultural development based
on the generally identified components that constitute modern agriculture. Over
the years, there has been the development and adoption of programs that tended
to generally support only increased production of commodities in the country.
Such programs have included, among others :
a. Farm
settlement schemes (FSS) in the early to mid 1950s for creating farmsteads of
the Israeli Moshav-type agriculture intended to increase commodity output and
create employment for young school leavers.
b. River basin
development authorities (RBDA’s) for the purpose of harnessing water resources
for farmers throughout the country.
c. Green
revolution scheme (GRS) that encouraged all Nigerians in both urban and rural
areas to go into agriculture for both commerce and provision of food for home
consumption.
d. Agricultural
development programs (ADP’s) in all states of the .federation to help organize
farmers into more productive agriculture through the provision of modern
inputs.
Each of these programs/schemes succeeded in momentarily
increasing food production only. There were no inbuilt components that
purposely catered for the processing and/or commercialization of the food
output. Thus, understandably, they failed as efforts aimed at developing the
agriculture sector. Recent attempts that have recognized agriculture’s current
level of performance and the fact that every aspect of Nigeria’s agriculture
sector needs attention have only listed specified areas that require attention.
For instance, the 2001 Rural Development Sector Strategy identifies the
following areas for immediate attention if agriculture and rural development in
Nigeria are to make the desired impact on the lives of the people:
a. Institutional
restructuring and role reassignment in the agricultural extension sub sector.
b. Agricultural technology development and natural resource
management
c. Physical and social infrastructural development.
d. Public intervention in specified areas of rural agriculture
to measure effectiveness.
e. Human capacity building in the agriculture sector.
Similarly,
the 2002 Agricultural Policy document that listed the new directions that
agricultural development in the country should take has also only listed the
various components of the agricultural sector without any attempt at
prioritizing the components.
1.2 Statement of the problem.
The specific problems to
address include;
§ Inadequate investment opportunities
in the sector.
§ What steps have been taken in past
years and in recent times to fuse agricultural proceeds into a source of
economic growth
§ In what ways have the government
policies on agriculture aid and encourage private and public participants in
the agricultural sector.
§ The damaging effects of inadequate
storage facilities which has caused great post-harvest loss.
1.3 Objectives of the study
The
objective of the study is to examine the impact of agricultural output on the
growth of the Nigerian economy, specifically. The objectives are:
§ To know if there are government
policies that support agriculture in Nigeria and if there are, how effective
and efficient.
§ To also help in highlighting
alternative procedures that can be taken to improve methods of enhancing
agricultural output effectively.
§ To make policy recommendations based
on the findings of the study.
1.5 Research Hypothesis
In an attempt to achieve
the above objective, the study is going to test the hypothesis:
i. H0: Agricultural output has
no impact on economic growth in Nigeria.
H1 : Agricultural
output has an impact on economic growth in Nigeria.
1.6 Significance of the Study
It is believed that the discovery of the study will benefit the government
tremendously, in terms of agricultural policies, budgetary allocation on agricultural
expenditure, the importance of agriculture and its effects on economic growth,
also to encourage participants both
public and private alike, provision of adequate subsidies , will enable the
farmers achieve whatever goals and objectives .
Furthermore, most areas of output
have their benefit as well as challenges in Nigeria thus the study renders
adequate solutions to such challenges. The literature review will serve as a
useful source of secondary database for the academic world and Nigeria at large
1.7 Scope and Limitation of the Study
The study focuses on the
Nigerian economy as a whole. That is agricultural sustainability in Nigeria,
Institutional reforms, Financial Reforms, Agricultural development programmes,
analysis of selected agricultural indicators, constraints of agricultural
output and strategies for maintaining agricultural growth in Nigeria.
Limitations are bound in the time series data available.
The study covers a span of 34 years;
the values are all evenly distributed about the mean.
