1.0 INTRODUCTION

In many developing countries, effective and efficient land use planning and management

is not well established. The most patent manifestation of this is the chaotic state of land use

activities in the cities. The physical, economic and social conditions of the African city has been

well documented (UNHABITAT, 2008). Rapid rates of urbanization have resulted in unplanned

and unregulated growth. Millions of Africas urban dwellers live in poverty in sub standard

housing and degraded environments. Much has been written highlighting the underlying factors

to which this state of affairs can be attributed (Nwaka, 2005; Oyesiku 2009, Mabogunje, 2002).

Urban land uses had been increasingly subjected to changes of different forms, sorts and

types since urban explosion of the 1970s. People move to cities en-mass from the rural hinterland

to the cities in anticipations to benefit from urban economy. However most Nigerian cities are

not planned and thus are not prepared for the surge in urban explosion that resulted from the

rural urban migration and the biological growth that made most Nigerian cities what they are

today- a decadence of humanity (Fabiyi, 2006).

Human use of land has altered the structure and functioning of the ecosystem (Vitonset et

al. 1997). The most spatially and economically important human use of land globally includes

cultivation in various ways, construction, reserves, protected lands and timber extraction (Turner

et al, 1994). Recently settlements and sprawl development are becoming large active land use

changes especially in the developing regions of the world. The pattern of land use can provide us

insight into the factors that have caused the land cover to change. The driving forces behind the

rapid urbanization in Africa today are the combination of rural-urban migration and natural

increase within the towns and cities themselves. Nigeria has been regarded as the most populous

nation in Africa with a teaming population of over 130 million crowded over a land area of about

923,000 square kilometers. It has over a hundred cities with population that passes for urban

centres. Nigerian cities Notably Lagos, Kano and Ibadan are among the first one hundred largest

cities in the world (World Gazetteer, 2005), which translates into pressures on land and thus high

urban dynamics.

Almost all African countries have a history of land use planning processes dating back to

the respective periods of colonial rule.Land use planning has been described as a process aimedat achieving orderly physical development with the overall aim of evolving a functional and

liveable environment where individual and common goals can be achieved. In urban centres, the

essence of land use planning is to ensure that urban activities are organized and developed in

physical space with due consideration for the protection of the public interest which include

health, safety, convenience, efficiency, energy conservation, environmental quality, social

equity, social choice and amenity (Adeagbo, 1998; Nnah et al, 2007).

The pressures on land orchestrated by increased rate of urbanization brought with it

intractable urban problems, such as poor environmental sanitation, pollution, crime,

unemployment and overcrowding among others. Many writers confirmed that Nigerian urban

centres are faced with rapid growth and development, which contribute to land use change. The

relationships between population increase, economic developments and land use pattern have

generated research interest over two decades and half. While the trend in lateral growth, the

pattern and direction of sprawl developments in many cities in Nigeria are limited by physical

barrier such as lagoon, Rocky Mountains and other natural features, the influx of people into the

cities complicated the urban condition through structural growth.

The population increase naturally creates adjustment and readjustment of human and land

use activities in space within urban systems thus causing lateral and structural changes. Lateral

changes occur when the city expands in geographic boundaries leading to sprawl and peripheral

developments while structural growth relates to increase in land use density within urban centres.

The low-density areas gradually become subjected to intensive use and thus become high density

or medium density use. Though land use changes are indirect consequence of national economic

growth, it is important to evaluate land use changes in the regional and the local context in order

to assist in anticipating the impacts associated with change and contribute to an understanding of

productive environmental sustainability.

This study focuses on the city of Ibadan, which comprises 11 local government councils,

with 5 in the inner city and 6 in the outer areas. Since its foundation in the 1800s, the city has

had rapid growth; in fact it was regarded as one of the pre-colonial urban centres in Nigeria. For

the purpose of this study, the core area of Ibadan which constitutes the five local government

councils listed below;

1. Ibadan north

2. Ibadan north-east

3. Ibadan north-west

4. Ibadan south-east

2.0 GENERAL OVERVIEW OF THE STUDY AREA

2.1 Historical perspective

Ibadan came into existence in 1829.According to local historians, Lagelu, the Jagun

(commander-in-chief) of Ife and Yoruba's generalissimo, left Ile Ife with a handful of people

from Ife, Oyo and Ijebu to found a new city, Eba Odan, which literally means 'between the forest

and plains.' The initial congregation of Ibadan after the occupation of the allied army of Ife, Ijebu

and Oyo three major Yoruba city-state communities, was along ethnic lines in 1820. Ijebus

lived in the South at Isale-Ijebu while the Egbas, led by Lamodi, moved far away from their

conquerors and settled at Yiosa. Ife and Oyo settled at Ojaba (Areola, 1994). The settlement

grew very rapidly under the protection of a series of warlords.

Ibadan is the capital city ofOyo State and the third largest metropolitan area in Nigeria,

after Lagos and Kano. Ibadan is also the largest metropolitan geographical area. At Nigerian

independence, Ibadan was the largest and most populous city in the country and the third in

Africa after Cairo and Johannesburg.

2.2 Geography

Ibadan is located in southwestern Nigeria about 120 km east of the border with the

Republic of Benin in the forest zone close to the boundary between the forest and the savanna.

The city ranges in elevation from 150 m in the valley area, to 275 m above sea level on the major

north-south ridge which crosses the central part of the city

2.3 Population growth


7/13

Until 1970, Ibadan was the largest city in sub-Saharan Africa (Lyold, 1967). In 1952, it

was estimated that the total area of the city was approximately 103.8 km2. However, only 36.2

km2

was built up. This meant that the remaining 67 km2

were devoted to non-urban uses, such as

farmlands, river floodplains, forest reserves and water bodies. These non-urban land uses

disappeared in the 1960s: an aerial photograph in 1973 revealed that the urban landscape had

completely spread over about 100 km2. The land area increased from 136 km2 in 1981 to 210-

240 km2 in 1988-89 (Areola, 1994: 101). By the year 2000, it is estimated that Ibadan covered

400 km2 (Onibokun, 1995). The growth of the built-up area during the second half of the 20th

century (from 40 km2 in the 1950s to 250 km2 in the 1990s) shows clearly that there has been an

underestimation of the total growth of the city. In the 1980s, the Ibadan-Lagos expressway

generated the greatest urban sprawl (east and north of the city), followed by the Eleiyele

expressway (west of the city). Since then, Ibadan city has spread further into the neighbouring

local government areas of Akinyele and Egbeda in particular. According to the National

Population Census Report, population growth of Ibadan has been remarkable with a population

of a 100,000 in 1851, to 175,000 in 1911 and 745,448 in 1952. The population rose to 1,141,677

in 1963 at a growth rate of 3.95% per annum. In 1991, the population rose to 1,829,300 and then

to 2,550,593 million in 2006. The population growth rate has been on the increase, although

census figures have been less than reliable.

2.4 Socio Economic Interaction

An interesting phenomenon of Ibadan City is its urban-rural homogeneity, reflecting

socio-economic ties. This accounts for a popular adage, Ibadan tile toko (Ibadan with homes in

the urban area and farmsteads in the rural area). Ibadan City today, has incorporated former rural

areas of Lalupon, Alakia, Olodo, Ogbere, Odo-Ona, Bode-Igbo and Moniya which lie at the

urban periphery of the city.

The phenomenon of homogeneity imposes movements on the people who are residents of

the peripheral communities on a routine basis. They particularly troupe into the metropolis

during days for business ventures. This often results in heavy traffic congestion in the central

Ibadan city. Indeed, Ibadan is often known for its unusual traffic congestions in the city and

especially around the surrounding open flea market areas

Literature Review and Theoretical Underpinning

One of the foremost problems associated with industrialization and civilization is the

urbanization and the consequent ills and fallouts. This is because industrialization and

civilization are pull factor for the rural-urban migrants as well as cross-national migrants. In

recent times most Nigerian cities especially Ibadan, Lagos and Kano have experienced

tremendous planned and unplanned growth due to population explosion, which led to congestion,

environmental degradation and urban socio-spatial upheavals. Planners and other urban

gatekeepers manage urban space and residents for the purpose of efficient functioning and

performance of urban systems. They however require the understanding of changed process in

urban land use and the interactions with the changed agents in order to discharge their functions

in urban space. In essence, managing and planning for towns require the understanding of the

forces and processes operating in them and the factors that naturally sort people of different

socio-economic status out in space. Information on the existing land use/land cover pattern, its

spatial distribution and changed process is a pre-requisite for planning, utilization and

formulation of policies and programme for making any micro and macro-level developmental;

unfortunately they are not readily available (Adeniyi, 1981).

Adeniyi (1981) observed that information on land use can now be more easily and

reliably obtained from remotely sensed and imagery. The continuous process of change and

development in the urban environment has assumed such dimensions that efficient and effective

methods of collecting, analysing and storing reliable spatial data on the physical, social and

economic features are indispensable for dealing with the manifold and complex problems of

urban management and planning. Since the old laissez faire approach to regulating the growth of

urban development is inadequate and no more relevant to the modern cities, there is a veritable

need for an institutional control of urban development (Agbola, 1985). This in essence requires a

sound knowledge of urban growth and a versatile tool for modelling and simulating such process

in order to afford urban planners the necessary tool and skill for monitoring urban land use

change.

This study is concerned primarily with urban land use pattern, urban landuse change and

urban growth, therefore the models of urban growth developed by Burgess (1925), modified by

Homer Hoyt (1933) and Harris and Ullman (1945) are relevant in this study.

Change process and change agent in urban Land use and land cover


9/13

Briassoulis (2000) review of literature enables her to infer that landcover conversion

involves a change from one cover type to another while land cover modification involves

alterations of the structure or function without a wholesale change from one type to another.

Similarly Turner et al. also note that landuse change is likely to cause landcover change, but land

cover may change even if the land use remains unaltered".

Nigeria has complex land systems where chiefs, families, individuals and government

own land. Traditional land tenure throughout Nigeria was based on customary laws under which

land was considered community property, but the customary law did little or nothing to avail

crisis emanating from the use and distribution of the land. In response to a potential crisis in land

distribution, the Federal Military Government promulgated the Land Use Decree of March 1978,

thus establishing a uniform tenure system for all of Nigeria with a view to opening the land to

development by individuals, corporations, institutions and governments. The decree gave state

and local governments authority to take over and assign any undeveloped land. Though this

decree has been operational for the past three decades and half land is still mainly in the hands of

individuals and families in most cities. The change process in Nigeria is heavily dependent on

the land holdings and the socio economic capacities of urban residents.

Dynamics of Urban Landuse Change

Afolayan (2010) carried out a detailed spatial analysis of Ibadan landuse pattern. In his

work, he classified Landsat satellite imageries of 1972, 1984 and 2006 using spectral signatures

for Urban, Sub-Urban, Water and Vegetation. From the analysis in Table 1, it can be observed

that the Land use of Ibadan has changed dynamically reflecting an expanding development into

the former rural and mostly vegetation areas. The remarkable change between 1972 and 1984

can be attributed to the oil boom and the antecedent infrastructural development. The massmigration from rural to urban communities in a way prompted drastic utilization of land

resources, especially in terms of building houses and erecting facilities for businesses.

1972 1984 2006

Land Use % % %Urban 5 14 15

Sub-Urban 19 52 53

Water 13 8 5

Rural / Vegetation 63 26 17

This trend understandably poses a big challenge to physical planning activities. It is imperative

that social and public amenities be made available to prevent Ibadan becoming a modern slum.

3.0 EXTENT AND COVERAGE OF THE PUBLIC/INSTITUTIONAL LANDUSE

3.1 Landuse Classification

There is no one ideal classification of land use and land cover, and it is unlikely that one

could ever be developed. There are different perspectives in the classification process, and the

process itself tends to be subjective, even when an objective numerical approach is used. There

is, in fact, no logical reason to expect that one detailed inventory should be adequate for more

than a short time, since land use and land cover patterns change in keeping with demands for

natural resources. Each classification is made to suit the needs of the user, and few users will be

satisfied with an inventory that does not meet most of their needs. In attempting to develop a

classification system for use with remote sensing techniques that will provide a framework to

satisfy the needs of the majority of users, certain guidelines of criteria for evaluation must first

be established.

To begin with, there is considerable diversity of opinion about what constitutes land use,

although present use of land is one of the characteristics that is widely recognized as significant

for planning and management purposes. One concept that has much merit is that land use refers

to, "man's activities on land which are directly related to the land" (Clawson and Stewart, 1965).

Concepts concerning land use activity are closely related and in many cases have been

used interchangeably. The purposes for which lands are being used commonly have associated

types of cover, whether they are forest, agricultural, residential, recreational, commercial or

industrial.Some activities of man, however, cannot be directly related to the type of land cover.

For example, hunting is a very common and pervasive recreational use of land, but hunting

usually occurs on land that would be classified as some type of forest, range, or agricultural land

either during ground survey or image interpretation. Consequently, supplemental information is

needed to identify lands used for hunting. Supplemental information such as land ownership

maps also is necessary to determine the use of lands such as parks, game refuges, or water

conservation districts, which may have land uses coincident with administrative boundaries not

usually discernable by inventory using remote sensor data.


11/13

For these reasons, types of land use and land cover identifiable primarily are used as the

basis for organizing this classification system. Agencies requiring more detailed land use

information may need to employ more supplemental data.In almost any classification process, it

is rare to find the clearly defined classes that one would like.The problem of inventorying and

classifying multiple uses occurring on a single parcel of land will not be easily solved. Multiple

uses may occur simultaneously, as in the instance of recreational land use (zoological garden)

located within institutional landuse (University of Ibadan).

CONCLUSION

A modern nation, as a modern business, must have adequate information on many

complex interrelated aspects of its activities in order to make decisions. Land use is only one

such aspect, but knowledge about land use and land cover has become increasingly important as

the Nation plans to overcome the problems of haphazard, uncontrolled development,

deteriorating environmental quality, loss of prime agricultural lands, destruction of important

wetlands, and loss of fish and wildlife habitat. Land use data are needed in the analysis of

environmental processes and problems that must be understood if living conditions and standards

are to be improved or maintained at current levels.
