This document summarizes a journal article about housing and central city slums in Ibadan, Nigeria. It discusses how Ibadan has grown from a historical war camp into a large city, putting pressure on housing and land. The article examines Ibadan's growth and development, the process of housing changes, socioeconomic impacts, and various planning initiatives to address issues like slums, inadequate infrastructure, and poor living conditions. It concludes that stopping slum development will be difficult and recommends approaches like slum upgrades, site services schemes, and using raw earth building technology.
This document discusses challenges for providing decent shelter and urbanization for urban poor groups. Over the next 25 years, more than 2 billion people will be added to urban areas in developing countries, requiring unprecedented growth in housing, infrastructure, and services. Currently, over 900 million people live in slums without adequate basic services. The document examines strategies for financing urban shelter development over the next generation to address this challenge. It assesses trends in mortgage finance, social housing, microfinance, and community funds. The proposal focuses on design criteria to improve housing, infrastructure, common spaces, and social and community development.
This document discusses urban environmental degradation in the Caribbean and Latin America. It defines key terms like urban area and environmental degradation. The main causes of urban environmental degradation are identified as poverty, pollution, overpopulation, lack of education, and industrialization. Effects include death, disease, biodiversity loss, and economic impacts. Proposed remedies include green restoration projects, smart city planning, poverty alleviation, and education.
This document discusses urbanization, housing, and infrastructure in Lagos, Nigeria. It notes that Lagos has experienced rapid urbanization and population growth that has outstripped investments in housing and basic infrastructure. As a result, many residents live in slums that lack access to clean water, sanitation, transportation, and other services. The government has acknowledged these issues and has begun projects to improve infrastructure through investments in roads, electricity, and other facilities. However, meeting future challenges of urbanization will require more efforts to boost housing supply and ensure all residents have access to basic infrastructure and services.
Slums are overcrowded, neglected urban areas characterized by substandard housing and squalor. They exist in most large cities around the world and are home to very poor residents living in inferior conditions. Slums lack basic infrastructure and are often plagued by disease, crime, and other issues due to overcrowding and poor sanitation. They have existed in cities throughout history in many forms.
Urbanization is increasing rapidly around the world and having significant impacts on the environment. By 2050, 64% of the developing world and 86% of the developed world will be urbanized. This rapid urban growth is causing problems like deforestation, air and water pollution, solid waste accumulation, and loss of agricultural land. Developing countries face more severe environmental impacts due to poor urban planning and inadequate infrastructure to handle the negative effects of urbanization. While urbanization enables economic growth, it also threatens the natural environment if not managed carefully through long-term planning and public-private partnerships that prioritize environmentally friendly development.

The document discusses traditional understandings of environmental injustice, which focus on disproportionate exposure of poor and minority groups to environmental hazards. It notes that environmental justice movements have demanded environmental equality. However, the document argues that there are missing pieces in traditional environmental justice frameworks, including a broader conception of livability, the role of place attachment and identity in community initiatives, and how political contexts shape neighborhood strategies for environmental revitalization.
Urban and rural communities can be defined in three main ways. Rural communities tend to be smaller in size with lower population densities. The occupations of rural residents typically involve agriculture, fishing, or food gathering. Rural areas have more limited resources, cultural activities, and education/health facilities compared to urban areas. Urban communities are characterized by having larger, denser populations with more complex social structures and diverse occupations. Urbanization has increased over time as more people migrate to cities for economic opportunities.
The document discusses housing problems in Mumbai, specifically the rise of slums. It identifies the main causes of housing issues as increasing population, pollution, high housing demand, rising land costs, and lack of planning. Slums have increased dramatically since the 1950s due to Mumbai's population tripling since 1947. Housing is scarce and expensive, while failed policies and corruption have exacerbated the problems. Slums lack proper sanitation and lead to health issues, as well as social problems like unemployment, violence, and child labor. Solutions proposed include providing housing and jobs for migrant workers, and empowering local authorities to improve infrastructure and services for slum dwellers.

This document provides background information on urban planning and renewal in Portland, Oregon. It discusses how urban planning aims to create livable communities but has not always distributed environmental amenities like parks and services equitably. The document focuses on three neighborhoods in Portland - Pearl District, Albina, and Lents - that experienced urban renewal led by the Portland Development Commission. It argues these neighborhoods show an inequitable distribution of amenities, with Pearl receiving more benefits than Albina and Lents. The document aims to analyze how amenities are defined, planned for, and distributed in Portland to assess equity across neighborhoods.
Urbanization has significant environmental impacts. It causes increased pollution in the form of greenhouse gases from fossil fuel combustion, acid rain from sulfur dioxide emissions, and degraded water quality from sewage. It also creates urban heat islands and modifies habitats. As more land is converted to urban uses, habitats are destroyed or fragmented and species are forced to adapt. Rapid urban growth in India is exacerbating these environmental problems as millions migrate to cities annually, and the urban population is expected to reach 74% of the total by 2025, placing huge demands on infrastructure and resources.
The document discusses urbanization and urbanism. It defines urbanization as the movement of people from rural to urban areas, increasing the proportion of the population living in urban settings. Urbanism is defined as the study of cities and the ways people interact with the built urban environment. The document outlines factors driving urbanization like industrialization and searches for better opportunities. It also discusses positive and negative outcomes of urbanization as well as government policies and characteristics of the urbanization process in India.
Slum areas are densely populated urban living areas characterized by poor-quality housing and lack of basic services. They exist in most major cities worldwide. Common characteristics of slums include overcrowding, inadequate infrastructure, and lack of tenure security. The rise of slums is primarily driven by rapid urbanization as people migrate from rural to urban areas seeking economic opportunities. However, low incomes prevent adequate housing and living conditions, leading to the formation of slums. Some of the largest slums globally include Dharavi in Mumbai, India and Kibera in Nairobi, Kenya, each home to over 1 million residents living in poverty with insufficient sanitation facilities.
DEVELOPMENT INDUCED DISPLACEMENT AND REHABILITATIONVismaya Nithin
Development-induced displacement occurs when communities or individuals are forced from their homes and lands for the purpose of economic development. There are two types of displacement: physical displacement, which results in relocation or loss of shelter, and economic displacement, which results in loss of assets or means of livelihood. Common causes of development-induced displacement include water supply projects, urban infrastructure development, transportation projects, energy projects, agricultural expansion, and the creation of parks and forest reserves. Rehabilitation aims to restore displaced individuals and communities to a satisfactory state by providing replacement housing, land, employment, and rebuilding social networks, but often fails to restore people's sense of identity and cultural link to the environment.
The document discusses the emergence and development of urban communities and rise of metropolises. It defines key terms like urban area and urbanization, and describes the factors that led to the formation of early cities like the development of agriculture and food surpluses. The document also examines urban structure models like the grid and concentric ring models, and discusses the development of cities and metropolises in the Philippines.
This document discusses urban growth and urbanization in India. It defines urban growth as the rate at which a city's population increases, and urbanization as the process by which there is an increase in the proportion of people living in urban areas. The major causes of urbanization in India are industrialization, which provides more jobs, as well as opportunities for better education, healthcare, and standards of living that attract people to cities. However, rapid urbanization can also lead to issues like overcrowding, poverty, and pollution. The document provides statistics on India's past and projected urbanization rates and their economic and social impacts.

Squatters settle on land, especially public or unoccupied land, without legal right or title, whereas slums refer to highly congested urban areas marked by deteriorated housing and living conditions. The UN defines slums as neglected parts of cities with appallingly poor living conditions lacking basic services. While strategies in the past tried to address slums through public housing and upgrading, problems have grown due to various issues such as lack of funding, interest, and tenure security for squatters. Effective slum upgrading requires local participation, affordability, sustainability, and provision of basic infrastructure like sanitation, roads/drainage, and water supply.
The document discusses a case study of the Balaju squatter settlement in Kathmandu, Nepal. It finds that residents are from a variety of socio-economic backgrounds and ethnic groups, with many migrating due to unemployment, poverty, or natural disasters. They engage in informal livelihood strategies like daily labor and small businesses. The settlement lacks basic infrastructure and residents live in vulnerable conditions. NGOs are working to improve livelihood opportunities and living standards, but long-term policy solutions are still needed to address urban poverty in Kathmandu's squatter communities.
Urbanization refers to the increasing proportion of people living in urban areas. It occurs due to rural-to-urban migration as populations increase and resources become scarce in rural areas, pushing people to cities where they believe living standards will be higher. Urbanization has major economic, social, cultural, and environmental impacts. It encourages changes in social and family structures, increases pollution and waste production, and places growing pressure on infrastructure and housing. While cities improve economies and facilitate cultural sharing, urbanization also leads to issues like unemployment, poverty, and the rise of slums if not properly managed.
Urbanization and the growth of cities is accelerating globally. By 2050, 75% of the world's population is projected to live in urban areas. Asian cities in particular will see huge growth, with China and India accounting for many of the fastest growing large cities. While Asian cities aim to become global cities on par with New York and London, many face challenges in building sufficient infrastructure and maintaining livability. However, the cultural vibrancy and economic opportunities of Asian cities continue to draw large migrant populations. Urban planning will be crucial for cities to manage issues around housing, pollution, and overcrowding that often accompany rapid urbanization.
The document summarizes information about gentrification and anti-gentrification movements from various sources. It defines gentrification as the renovation of deteriorated neighborhoods that results in increased property values and the displacement of low-income residents and small businesses. It discusses who is affected by gentrification and some of its economic and social consequences. It then profiles several grassroots anti-gentrification organizations and movements that have formed to fight displacement, including Right to the City, #LoveTheHill, and the Anti-Eviction Mapping Project.
Factors like ambivalence of the ruling government, population explosion, dearth of housing and land has lead to squatter settlements. The reasons for these settlements are manifold. Read the following article to find out what gives rise to squatter settlements.
This document provides information about urbanization and discusses it in the context of Dubai and Asia. It begins with entry tasks asking students to consider how Dubai's population has changed over time and what causes populations to increase or decrease. The objectives are for students to describe urbanization and analyze its benefits and challenges. The document defines urbanization as the increasing number of people living in urban areas. It provides statistics about urbanization trends in Asia, such as many people in poor urban areas lacking basic services. Students are directed to read case study articles on urbanization in China and India and answer questions. They are also asked to research urbanization statistics for Dubai.
Urbanization in the Philippines has led to over 60% of the population living in urban areas by 2010, burdening urban systems and increasing problems of poverty, healthcare access, and pollution. A key driver of urbanization is the migration of people from rural areas seeking better access to facilities, jobs, and education in cities. However, urban areas now struggle to provide adequate housing, infrastructure, and services for the growing populations. If current trends continue, the Philippines is estimated to have over 600 urban centers by 2020.
Understanding the Grassroots Dynamics of Slums in Nairobi: The Dilemma of Kib...drboon
A lot of literature on urban development in developing countries has entirely focused on the nexus between rapid urbanization, Gross Geographic Product (GGP) and poverty growth with little research that demonstrates what this impacts on urban sustainability especially with increasing slums in rapidly urbanizing African countries. Available research has focused entirely on increasing poverty level in urban Africa and its mitigation without a clear direction on what this means to slums improvement and urban sustainability. This papers aims to give a conceptual analysis that will help to understand the dynamics of urban sustainability and slums development. The historical perspectives and current realities of Kibera slums in Nairobi are reviewed.

This document defines key sociological concepts like society, community, urban and rural areas. It describes the characteristics of societies and communities. Rural areas are more homogeneous with strong social control, while urban areas are heterogeneous with greater diversity and social change. The interaction between urban and rural communities is also explored. Urbanization is discussed as resulting from industrialization and influx control removal in South Africa. Informal settlements emerge due to factors like rural depopulation, lack of work, and the hope of better opportunities in towns. However, settlers often find no housing, services, or work in the settlements.
Urban flooding and vulnerability of nigerian citiesAlexander Decker
Urban flooding has become a recurring issue in many Nigerian cities, including Awka and Onitsha in Anambra State. The study examines the causes and impacts of flooding in these two cities, with the goal of recommending measures to address the problem. Primary and secondary data show that flooding causes major losses and disruption, but the cities have received limited government support to address environmental issues. Key factors contributing to flooding include inadequate drainage infrastructure, poor drainage design and construction, uncontrolled development that blocks drainage, and improper solid waste management. To reduce vulnerability, the study recommends developing and implementing comprehensive urban flooding control programs that involve the public.
The document discusses urbanization in Bangladesh and its impacts. It notes that urbanization refers to the migration of people from rural to urban areas, resulting in population concentration and growth in cities. In Bangladesh, urbanization has occurred rapidly, with over 25% of the population now living in urban areas, most concentrated in Dhaka and other large cities. However, rapid and unplanned urbanization has led to several issues such as pollution, water logging, transport problems, and the degradation of urban environments and infrastructure. Addressing the challenges of urbanization in a sustainable manner requires integrated planning and development efforts across Bangladesh.
Urbanization in Bangladesh has increased rapidly in recent decades as the population migrates from rural to urban areas. This unplanned urbanization has led to several issues in major cities like Dhaka, including extreme overpopulation, shortage of housing and utilities, increased pollution, and environmental degradation. While urbanization has contributed to economic growth, it has also exacerbated problems like rising inequality, poverty, and pressures on infrastructure if not properly managed. Addressing the challenges of urbanization in a sustainable manner requires improved planning, management of rural-urban migration flows, and balanced development across urban and rural areas of Bangladesh.
Slums have been a problem in Delhi, India for decades. Approximately half of Delhi's 18 million residents live in slums or unauthorized colonies without proper sanitation or waste disposal. Living conditions in slums spread diseases, especially affecting children, as water is often contaminated and access to healthcare is limited. The persistence of slum issues in Delhi despite years of efforts is largely due to high levels of corruption within the Indian government.

This document assesses housing conditions in urban slums in Abuja, Nigeria using geospatial analysis. It analyzes slum areas in Durumi, Garki-2, Gishiri and Jabi neighborhoods. Key findings include:
1) Water sources are often open wells serving dozens of families, with low water quality associated with overcrowding.
2) Solid waste disposal is typically illegal dumping, allowing rubbish to accumulate without routine collection.
3) Building walls are commonly made from substandard materials like mud, clay, wood or cardboard that do not meet structural requirements.
Residents’ perception on environmental impacts of urban informal enterprises ...Alexander Decker
This document summarizes a research study on residents' perceptions of the environmental impacts of urban informal enterprises in Ibadan, Nigeria. The study administered questionnaires to over 1,600 residents across low, medium, and high residential areas. Six indices were developed to measure perceptions on various environmental effects. Results showed residents strongly agreed that waste from the enterprises makes areas dirty and litters streets. Noise, odors from waste, and shops blocking drainage were also issues. Correlation analysis found the physical, behavioral, environmental, land use, and economic characteristics of the enterprises all impacted the environment. The paper recommends policies and legislation for better waste management to promote more sustainable cities.
Residents’ perception on environmental impacts of urban informal enterprises ...Alexander Decker
The document analyzes residents' perceptions of the environmental impacts of urban informal enterprises in Ibadan, Nigeria. A survey of over 1,600 residents found that the highest levels of agreement were with the statements that informal enterprise waste makes the environment dirty (average rating of 4.14) and litters the streets (4.12). Residents also perceived that the enterprises generate high noise levels (3.85) and deface the environment (3.90). The results indicate various environmental issues related to waste management and aesthetics. The document recommends policies and legislation to promote proper waste management from the informal sector and sustainability in Nigerian cities.
This document discusses settlement patterns and rural-urban migration in Uganda. It defines and describes three main types of settlement patterns: nucleated, linear, and dispersed. It then discusses factors that influence rural-urban migration in Uganda, including push factors like lack of opportunities and land in rural areas, and pull factors like employment and educational opportunities in cities. The document also discusses some positive and negative impacts of human interaction with the environment, such as using renewable energy and planting trees (positive), and pollution, climate change, and deforestation (negative).
Urbanization is rapidly increasing worldwide, including in developing countries. Rapid urbanization presents significant challenges, such as unemployment, poverty, inadequate infrastructure, and environmental degradation in many developing country cities. Over half the world's population now lives in urban areas, crowded into just 3% of the Earth's land. By 2030, 65% of the global population is expected to be urbanized. Effective urban planning, infrastructure development, and management are needed to address the problems caused by rapid urban population growth and density in cities.
The document discusses different types of urban settlements according to size, shape, function, and location. It describes nucleated, linear, and dispersed settlement shapes. Industrial towns, market towns, ports, and seaside resorts are discussed according to function. Rural settlements are contrasted with urban settlements based on demographics, land usage, population density, transportation, and economic dependencies. Rapid urbanization in developing countries and the growth of megacities are also summarized.
The document discusses challenges related to slum areas in India. It begins with an acknowledgement section thanking those involved in the project. It then defines slum areas and discusses various causes that lead to the creation and expansion of slums such as rural-urban migration, lack of affordable housing, and poverty. The impacts of slums are then outlined, including poor living conditions, health hazards, and social problems. The document concludes with recommendations for governments to improve conditions for slum residents and prevent new slum formation through increased access to services, infrastructure, and affordable housing. It also shares personal experiences of students visiting a slum area in India.
The informal sector and the environment in nigerian towns what we knw and w...Dr Lendy Spires
This document summarizes existing research on the informal sector and its relationship to the environment in Nigerian towns. It is known that the informal sector provides important employment opportunities for low-income individuals and absorbs migrants from rural areas. However, activities in the informal sector also generate waste and pollution that municipalities struggle to manage effectively. While studies have documented general environmental problems, there are few detailed case studies analyzing the specific environmental impacts of different informal sub-sectors. The document calls for more field research focusing on how particular informal activities affect the local environment in order to develop new policies that balance livelihoods and sustainability.
Urban poverty and juvenile delinquency in nigeriaAlexander Decker
This document summarizes research on the relationship between urban poverty and juvenile delinquency in Nigeria. It examines inmates at the Port Harcourt Remand Home as a case study. The study found that urban poverty is a driving force behind juvenile crime in Port Harcourt, as children from poor homes were more likely to commit crimes than those from wealthy homes. It also found that the Remand Home is ill-equipped to rehabilitate juvenile offenders. The document reviews previous empirical research on urban poverty and juvenile delinquency in Nigeria and outlines the objectives and hypotheses of the case study.
This document summarizes a study on the risks of rapid urbanization in Davao City, Philippines. The study finds that rapid urbanization can lead to issues like overpopulation, poor infrastructure, and environmental and health problems. Specifically, it identifies risks such as traffic issues from population growth, inadequate electricity, water, and transportation systems to support infrastructure growth, increased health problems for urban poor from factors like pollution, and greater greenhouse gas emissions contributing to climate change. The researchers recommend adopting strategic infrastructure development policies to help manage uncontrolled urban expansion.
The document discusses the rise and development of cities globally. It describes factors that contributed to urbanization like improvements in agriculture, transportation, and industries. Models of urban growth patterns are presented, including concentric zone, sector, and multiple nuclei models. Challenges faced by large cities are outlined, such as generating revenue, urban decay, and poverty. Environmental issues in global cities like overpopulation, resource depletion, and pollution are also summarized. Finally, some of the largest and most influential cities in the world are listed.

Women with polycystic ovary syndrome (PCOS) have elevated levels of hormones like luteinizing hormone and testosterone, as well as higher levels of insulin and insulin resistance compared to healthy women. They also have increased levels of inflammatory markers like C-reactive protein, interleukin-6, and leptin. This study found these abnormalities in the hormones and inflammatory cytokines of women with PCOS ages 23-40, indicating that hormone imbalances associated with insulin resistance and elevated inflammatory markers may worsen infertility in women with PCOS.

It involves user testing methods like usability testing and interviews to identify usability problems in areas like navigation, design, purchasing processes, and customer service. The framework specifies goals for the evaluation, determines which website aspects to evaluate, and identifies target users. It then describes collecting data through user testing and analyzing the results to identify usability problems and suggest improvements.
A universal model for managing the marketing executives in nigerian banksAlexander Decker
This document discusses a study that aimed to synthesize motivation theories into a universal model for managing marketing executives in Nigerian banks. The study was guided by Maslow and McGregor's theories. A sample of 303 marketing executives was used. The results showed that managers will be most effective at motivating marketing executives if they consider individual needs and create challenging but attainable goals. The emerged model suggests managers should provide job satisfaction by tailoring assignments to abilities and monitoring performance with feedback. This addresses confusion faced by Nigerian bank managers in determining effective motivation strategies.

It presents lemmas showing the uniqueness of limits in these spaces and the equivalence of different definitions of convergence. The goal of the paper is then stated as obtaining a unique common fixed point theorem for generalized D*-metric spaces.
A trends of salmonella and antibiotic resistanceAlexander Decker
This document provides a review of trends in Salmonella and antibiotic resistance. It begins with an introduction to Salmonella as a facultative anaerobe that causes nontyphoidal salmonellosis. The emergence of antimicrobial-resistant Salmonella is then discussed. The document proceeds to cover the historical perspective and classification of Salmonella, definitions of antimicrobials and antibiotic resistance, and mechanisms of antibiotic resistance in Salmonella including modification or destruction of antimicrobial agents, efflux pumps, modification of antibiotic targets, and decreased membrane permeability. Specific resistance mechanisms are discussed for several classes of antimicrobials.
A transformational generative approach towards understanding al-istifhamAlexander Decker
This document discusses a transformational-generative approach to understanding Al-Istifham, which refers to interrogative sentences in Arabic. It begins with an introduction to the origin and development of Arabic grammar. The paper then explains the theoretical framework of transformational-generative grammar that is used. Basic linguistic concepts and terms related to Arabic grammar are defined. The document analyzes how interrogative sentences in Arabic can be derived and transformed via tools from transformational-generative grammar, categorizing Al-Istifham into linguistic and literary questions.
A time series analysis of the determinants of savings in namibiaAlexander Decker
This document summarizes a study on the determinants of savings in Namibia from 1991 to 2012. It reviews previous literature on savings determinants in developing countries. The study uses time series analysis including unit root tests, cointegration, and error correction models to analyze the relationship between savings and variables like income, inflation, population growth, deposit rates, and financial deepening in Namibia. The results found inflation and income have a positive impact on savings, while population growth negatively impacts savings. Deposit rates and financial deepening were found to have no significant impact. The study reinforces previous work and emphasizes the importance of improving income levels to achieve higher savings rates in Namibia.
A therapy for physical and mental fitness of school childrenAlexander Decker
This document summarizes a study on the importance of exercise in maintaining physical and mental fitness for school children. It discusses how physical and mental fitness are developed through participation in regular physical exercises and cannot be achieved solely through classroom learning. The document outlines different types and components of fitness and argues that developing fitness should be a key objective of education systems. It recommends that schools ensure pupils engage in graded physical activities and exercises to support their overall development.
A theory of efficiency for managing the marketing executives in nigerian banksAlexander Decker
This document summarizes a study examining efficiency in managing marketing executives in Nigerian banks. The study was examined through the lenses of Kaizen theory (continuous improvement) and efficiency theory. A survey of 303 marketing executives from Nigerian banks found that management plays a key role in identifying and implementing efficiency improvements. The document recommends adopting a "3H grand strategy" to improve the heads, hearts, and hands of management and marketing executives by enhancing their knowledge, attitudes, and tools.

Abstract
Ibadan is among the first one hundred largest cities in the world which translates into pressures on land and thus high
urban dynamics. This study is an effort to identify and highlight the housing and central city slum trend in Ibadan, a city
in the South West Region of Nigeria. Its goal is to examine the process of change of Ibadan from a well-known
historical war camp of the Yoruba people to its present state and its capacity to become a slum city. The Objectives are
to examine the growth and development of Ibadan city; examine the process of housing changes; Identify the socio
economic aspect of the change process; Provide explanation to structural and lateral changes in the city; and evaluate
various planning initiatives.
This paper addressed the adverse effects of the unprecedented population growth and consequent increase in
urbanization of Ibadan on the inhabitants. The poor socio-economic state of the nation as well as its various housing
implications was examined. The paper concludes that the government effort to stop slum development will be to no
avail unless they accept that slums have become inevitable phenomenon in urban areas which has no quick fix solution.
However, it could be nipped in the bud using the following recommended approaches: slum upgrade option, sites-and-
services scheme and embracing raw earth building technology.
Key Word: Housing, City, Slums, Urbanization
1.0 Introduction
According to (Tomori, 2010) the growth of Ibadan into metropolitan city brings luxuries and opportunities, real or
imagined which are not found in the rural areas. These attractions lead city to grow at a rate that become difficult to
manage. Essentially, undue presence is exerted on the existing public utilities while services are extended legally and
illegally to the unplanned new areas. So, it seems that the more utility services provided, the more they are demanded.
As a result, the utility services become inadequate and thus increasing the cost of doing business which in turn mitigate
against all efforts to reduce the widening poverty gap. This actually calls for effective administrative framework, good
governance and urban management capacity. There should be coordination among the various institutions which are
responsible for the planning and management of the urban environment. Ibadan for a long time has no master plan
leading to uncontrolled urban growth and haphazard and unsustainable development. Refuse collection, deforestation
and flooding of the city has defied solution for almost a century now (Tomori, 2010). The solutions lies in the holistic
mobilization of resources, demonstration of political will, socio economic interventions, regional planning and other
essential elements of urban maintenance and growth must be marshaled in an integrated manner that allow the extended
metropolis to operate as an integrated system and yet permit each community or neighborhood to achieve its goal of
corporate existence.
In line with (Labinjoh, 1991) the city is on autonomous phenomenon, the exploration of whose historical, cultural
economic and political ramifications is not only intellectually exciting, but also contributes immensely to our
understanding of the larger society. Just as there have been great empires in history, there have also been great cities
past and present reflecting various flourishing civilizations. That can be said of Ibadan which indeed is a city of earlier
epoch that seems to have refused to change (Labinjoh, 1991). Just as empires rose and fell in history some cities have
developed tremendously while others have simply decayed. Ibadan is a curious mixture of the two experiences: it has
not really developed economically and physically, but it has not decayed. Ibadan city was, and still is, a place of
conflict, an arena in which rival classes and emerging status groups struggled for power, a place in which the major
changes, structural, institutional and ideological, in the larger society produced fundamental reactions affecting the
structure of social and political behaviour.
1.2 Definition of Slums and Squatters
The (Britannica, 2003) defined a slum as a densely populated usually urban area marked by crowding, dirty run-down
housing, poverty, and social disorganization. Also, slums as defined by (United Nations, 2007) are run-down area of a
city characterized by substandard housing and squalor and lacking in tenure security. According to (Fourchard, 2003)
slums are defined as those areas that are yet to develop in terms of good planning and settlement. Some of the
characteristics of slums are that they lack infra-structural facilities, have no planned layout and the residents are
21

Vol 2, No.9, 2012
predominantly poor and illiterate. Slums are areas that concentrate low-income earners, low-cost houses, possibly mud
houses, no layout and poor inhabitants.
According to (World Bank/UNCHS, 2000) slums are highly congested urban areas, inhabited by urban squatters,
marked by deteriorated, unsanitary buildings, poverty, and social disorganization. In addition, they are also considered
as a residential area in an urban locality inhabited by the very poor who have no access to tenured land of their own.
Therefore, slums could also be referred to as squatter settlements. The slums are characterized by substandard housing
units, acute shortage of dwelling units which resulted in overcrowding, poor urban living conditions, and services and
infrastructure below the adequate or minimum levels, and indeed high crime rates (World Bank/UNCHS, 2000).
In line with (United Nations, 2007) The term has traditionally referred to housing areas that were once relatively
affluent but which deteriorated as the original dwellers moved on to newer and better parts of the city, but has come to
include the vast informal settlements found in cities in the developing world. Although their characteristics vary
between geographic regions, they are usually inhabited by the very poor or socially disadvantaged. Slum buildings vary
from simple shacks to permanent and well-maintained structures. Most slums lack clean water, electricity, sanitation
and other basic services (United Nations, 2007).
According to (Indymedia, 2008) the characteristics and politics associated with slums vary from place to place. Slums
are usually characterized by urban decay, high rates of poverty, illiteracy, and unemployment. They are commonly seen
as breeding grounds for social problems such as crime, drug addiction, alcoholism, high rates of mental illness, and
suicide. In many poor countries they exhibit high rates of disease due to unsanitary conditions, malnutrition, and lack of
basic health care. Rural depopulation with thousands arriving daily into the cities makes slum clearance an uphill
struggle. A UN Expert Group has created an operational definition of a slum as an area that combines to various extents
the following characteristics: inadequate access to safe water; inadequate access to sanitation and other infrastructure;
poor structural quality of housing; overcrowding; and insecure residential status (United Nations, 2007).
1.3 Costs of Living in Slums
Total financial expenditures of households cannot be provided for due to methodological reasons, but costs of rent,
transportation and water can be approximately calculated. If the rent is one of the cheapest in Ibadan, living in the area
presents additional costs due to the necessary charges for transportation and water. Another major problem in the core
area is the unavailability of water and light (Akinyode, 1998). The level of insecurity in the slum area reveals some
interesting findings (Idemudia, 2003). The poverty of the area and its exclusiveness (pathways, no public places, no
place of work, poor knowledge of his neighbours) so, there is more feeling of insecurity in the slum than in residential
areas. The slum areas are not areas of moral and social deviance, criminality and delinquency (Mabogunje, 1968).
2.0 Slum Formation Processes and Spatial Types in Ibadan
According to (Agbola 1987), two types of slum exist in Nigerian cities. There are the traditional slums arising in towns
from the decay of existing structures and there are spontaneous slums created by squatters on illegally acquired lands. If
this pattern represents the majority of the slums in Ibadan, it is necessary to reconsider the use of such terms as
“traditional” and “spontaneous”, and to show that some slums can appear outside the inner city on legal land. In line
with (Urban Leadership, & Grigg, 2010) despite a great range of varieties mentioned above, slums fall into two broad
categories: declining areas and progressing settlements each of which can, for the purposes of expanded analysis, be
broken into:1. Declining areas: old city centre slums; and new slum estates.2. Progressing settlements: squatter
settlements; and semi-legal subdivisions.
2.1 Inner-city slums: Inner-city slums gave birth to the concept of the slum; the process whereby central,
prosperous residential areas of cities undergo deterioration as their original owners move out to newer, more salubrious
and more fashionable residential areas. This is a commonplace and predictable consequence of the growth and
expansion of cities, manifest by both an increase in the central commercial and manufacturing areas and activities, and
the influx of migrants looking for employment opportunities. Initially, the housing vacated by the better-off is still
structurally sound and serviceable, and provides an ideal housing opportunity for those willing to make do with less
space and shared amenities. The location of buildings provides residents with good access to employment opportunities.
Since the buildings were originally built for middle- and high-income groups, they are usually reasonably well serviced
with urban infrastructure, though, over time, as dwellings are increasingly subdivided and the level of overcrowding
grows, strain on those services can reach breaking point.
Agreeing with (Amole etal.1991) in Ibadan, the inner-city core area consists of the oldest, the lowest-quality and the
highest- density residences of the city. Housing is constructed of mud, with virtually no sanitation facilities. It is highly
residential, up to 90% in Elekuro ward, and the simultaneous presence of many old markets and street trading in the
area cause traffic congestion and exacerbates overcrowding while providing essential employment and services. Some
of the wealthier people of Ibadan, who were born in the core area, have kept their family house for cultural and familial
reasons, although they now live in villas in the new government estates. However, the buildings and land that they
22

Vol 2, No.9, 2012
occupy remain sacred to the original owning family and it is very difficult to change them from residential use. They are
of little economic value but are precious to their multiple-related owners.
2.2 Slum Estates: This category differs from the traditional city centre slum in that the structures are relatively
new and generally not in private ownership. Examples include both public housing estates and housing built by industry
or to house industrial workers, such as the hostels that have experienced social problems arising from overcrowded and
pressured conditions, making residents vulnerable to organized crime and political exploitation. Ironically, in Ibadan
city, much of the public housing built between the 1950s and 1970s to re-house the residents of central city slums and
squatter settlements, typically in four- to five-storey tenement blocks with minimal, if any, community amenities, has
itself now joined the stock of slums. Housing and living conditions in public housing estates have been further
worsened through the lack of appropriate dweller control or involvement in the day, to-day management and
maintenance of either individual dwelling units or the housing estates as a whole, including their public infrastructure.
Often, this has also been accompanied by the omission, closure or breakdown of common amenities and facilities,
usually due to shortages of resources to address the extent of need. Another common reason for the deterioration of
relatively new public housing estates has been their peripheral location on the edges of cities where land was available,
but access to work, markets, kin and social amenities was not. The relative isolation of such estates meant that the cost
of transport was often unaffordable to the low, income inhabitants. As a result, they became abandoned by all but the
most destitute and desperate.
2.3 Recent slums: Recently developed slum neighbourhoods are often similar to the consolidated informal
settlements, but are newer and unconsolidated. Their newness is expressed in poorer, less permanent materials,
especially in settlements where residents are unsure of whether and for how long they will be allowed to stay before
being evicted. where evictions are common, or on sites where they are unlikely to be left alone, shacks are likely to be
very rudimentarily built of recycled or very impermanent materials (such as straightened oil drums, used corrugated
metal sheets, plastic and canvas sheets, cardboard cartons and discarded timber). Infrastructure is likely to be absent or
only available through clandestine connections. New or recently established slums tend to have lower densities as there
are fewer constraints and less competition for the land; recently developed slums are generally found on the periphery
of the built-up area of the city, or in pockets of even more marginal land than the more established slums. Increasingly,
occupants of the newer slums often use the grid-iron layout; there are several advantages in adopting grid layouts: It is
easy to layout; there is a stronger likelihood of obtaining urban services and recognition if the settlement is orderly;
there are likely to be fewer disruptions and demolitions when services are installed.
2.4 Peripheral: Slums on the city fringes are, either squatter settlements in which households have invaded
(usually public) land, or they occupy land that has been subdivided and for which they have paid or entered a rent-
purchase arrangement with the developer or landowner. The urban periphery has distinct advantages over more central
and urbanized areas as there is less competition for the use or control of land, especially if it is located outside of the
municipal boundaries. Peripheral slums can be quite large settlements since they are rarely constrained by competing
development.
In many cases, the quality of housing is relatively good - significantly better than is to be found in the adjoining rural
areas - but the level of services is generally low. While this is not a great hazard to health and amenity when the overall
density is low - as it can be during the early period of development - it can become a serious problem as the slum grows
larger and denser. An overriding problem facing peripheral slum dwellers is the low level of access and high cost of
transport to jobs, markets, schools and the centres of administration of public services. Thus, households living in
Peripheral urban areas can spend up to 30 per cent of their incomes on transport, or as much as three to four hours a day
walking to and from work and school. A very significant feature of informal settlements on the urban periphery is their
potential for efficient and effective upgrading through the provision of infrastructure and public services,
3.0 Ibadan Central City Slum
As mentioned in the section on 'Inner-city slums,' central- city slums tend to have been formed by the classic process
where central, prosperous residential areas of cities undergo deterioration as their original owners move out to newer,
more salubrious and more fashionable residential areas. Initially, the housing vacated by the better-off, which generally
has reasonable infrastructure and services, is ideal for those willing to trade off less space and shared amenities in for
access to employment opportunities. Centrality of location does not necessarily imply the old city, or the central
business or commercial centres of cities. As used here, it also embraces formal industrial areas, ports, wholesale
markets and other areas of employment that are some distance from the central business district (CBD). Residents of
slums that are located close to such zones are able to benefit from the high concentrations of employment opportunities,
especially those related to unskilled and casual jobs. They are also likely to be better off in terms of transportation
because of the tendency for cities to grow outwards radially and, therefore, to have roads and transport converging on
centres of formal employment. This makes centrally located slums much more suitable for unskilled workers. If the
neighbourhood originated in the old city centre, then it may also have the benefit of substantial buildings and a
23

Vol 2, No.9, 2012
reasonable level of infrastructure and services, though it may have fallen into disrepair and infrastructure may be
severely overloaded.
3.1 The Challenges of Ibadan City Slums,
According to (Urban Leadership, & Grigg, 2010) spatial forms and the physical location of slums vary from region to
region, from city to city and even within the same city. The working definitions of slums, suggested above, as non-
complying with building regulations and standards, having inadequate basic services provision and insecure tenure
status, leave a great deal of room for variation, from marginally inadequate in one feature to being a place of multiple
insanitary and deprived conditions. Though the term slum includes the traditional meaning of housing areas that were
once respectable or even desirable, but which have since deteriorated, it has come to include the vast informal
settlements that are quickly becoming the most visual expression of urban poverty. Indeed, the majority of dwellings in
most of the world's developing cities are in slums
In line with (UN-HABITAT. 2003) many important historic cities are in danger of terminal obsolescence. Many
peripheral neighbourhoods, even in the same cities, are being constructed with the characteristics of slums from day
one, or soon after. Some of these are government or employer built estates of low cost housing, providing minimal
accommodation for formal sector workers. These often quickly deteriorate through lack of maintenance and unplanned
levels of occupancy. Some are even built to standards of servicing that render them inadequate. Others are informally
built, peripheral settlements that ring many developing cities. There is astonishing dynamism displayed in the founding
and improvement of these settlements, and the lessons learned from them should not be ignored. At their earliest stage,
they may be extremely poorly built and on serviced; but through the years they can develop into sturdy, well-serviced
neighbourhoods. The transition from one to the other is not, however, automatic; encouragement and de facto security
are important. In central city areas, many dwellings are steeped in family history and are precious, although they are of
little value. In addition, some households are so poor that even a ramshackle shack is more than they can bear to lose.
Many of the slums are very tiny, perched on a traffic island, on a small piece of back land in the business district, next
to the railway goods depot. The issues they face may have less to do with servicing, as they can often free-ride on other
people's water supply and sanitation. Instead, they have greater issues of security and recognition, and concerns about
who will defend them against threats of eviction. At the same time, they may be holding up important development, or
creating dangers for themselves and others. The task of solving the dilemma they present for city authorities is,
therefore, beset with problems. Were all of these slums simply illegal, then the tenure issue and their security would be
much clearer. However, they possess many grades of security, leaving a much more complex context of intervention for
the authorities and a more difficult future of improvement or decline to predict. This dynamic trajectory of the
neighbourhood, whether it is in decline or progressing, was memorably expressed many years ago as the dichotomy of
slums of despair or slums of hope (Lloyd, 1979).
4.0 Ibadan Present Condition
Ibadan, one of the largest indigenous metropolitan areas in sub-Saharan Africa, has an estimated population of about
two million coming from different parts of Nigeria and other parts of the world. The city, located on a major transport
route to the northern parts of Nigeria, is the largest contemporary traditional Yoruba town.
The residential structure of the city can be divided into three homogenous groups: the core, the periphery, and the
intermediate areas. The core area is the traditional area of the city, characterized by high levels of poverty, high density
of population, and lack of physical planning, dilapidated buildings, poor sanitation, inadequate health facilities, slum
settlements, high level of illiteracy, and low level of socioeconomic activities. The intermediate areas, including Molete,
Oke-Ado, Mokola, Eleyele, Agbowo, etc., are areas of late development, mainly inhabited by migrants from other
Yoruba towns and ethnic groups, or those who moved out of family compound houses located in the tradtional areas of
the city. The density of population here is lower than those of the traditional areas, and housing is also moderately
scattered, although these are not well laid-out as those found in the peripheral areas. The periphery, including Old and
New Bodija, University of Ibadan, Jericho, Iyaganku Government Reservation Areas, and other emerging well-planned
areas of the city are inhabited mostly by the elite. These feature well laid-out residential apartments, low density of
population, and essential social services. Healthcare needs of the population of the metropolis are served by the
University College Hospital, two State hospitals, and several private medical facilities, in addition to traditional medical
practitioners scattered all over the city (UN-HABITAT. 2003).
Ibadan metropolis used to be under one local Government, the Ibadan Municipal Government before it was split into
five local government areas (LGAs) Southeast, Northeast, Southwest, Northwest, and North Central in 1991. Northeast
and southeast, these two LGAs contain the largest slum areas in the city. The characteristics of these two LGAs, which
fit the criteria for slums, include high density of population, inadequate health, education and social facilities, poor
sanitation, inaccessible road network, lack of potable water, and erratic electricity supply. Housing patterns show no
distinction between buildings, located in large family compounds (with up to three or four families in one building).
Similarly, leisure or recreational facilities are non-existent. The lack of recreational facilities is, perhaps, responsible for
24

Vol 2, No.9, 2012
strong community organizations, such as cooperative societies that abound in the area and which enable residents to
come together to implement community development activities in form of gated communities. The population
structure consists of predominantly young people, with the majority aged 15-30 years, who work mostly as
cobblers, seamstresses, tailors, and barbers and in other handicrafts. Although the population is predominantly
Christian and Muslim, there is an active worship of deities. Overall, the majority of young people have some
formal education, but many are currently out of school. Only a few communities have government health
facilities and these are sparsely equipped. The only reliable health facility that residents patronize is the state-
owned general hospital (Adeoyo Maternity Hospital is the nearest health facility owned by State government that
is available to the communities. It is nearer than the more popular University College Hospital owned by Federal
government, where special services are rendered), which is several kilometers away from many communities.
Consequently, patent medicine stores (chemists) and itinerant medicine sellers serve the health needs of
residents.

5.0 Ibadan and Environmental Issues
Agreeing with (Tomori, 1979) as the metropolitan area of Ibadan continues to witness series of developmental
activities, environmental risks arise from a wider array of sources which include air pollution from vehicles; household
energy use; and industrial and power plants; land and water pollution from solid wastes and untreated sewage and
traffic congestion, accidents and noise. These problems have more direct and immediate negative impacts on human
health and safety, especially for the poor and on business productivity. Another consequence of poorly managed
urbanization is the settlement on unstable and risky locations such as along Ogunpa, Kudeti, Ogbere and Orogun
floodplains and hillside of Oke-Are, Oke-Aremo, Sapati and Mokola hills in the centre of the city. This phenomenon is
partly responsible for the Ogunpa flood disasters and soil erosion. The urban poor live in crowded slums within the core
residential areas of Ibadan (such as Ayeye, Agbeni, Bere etc), with limited basic infrastructure services, and without
land and personal security. Within the city core residential areas, there is lack of comprehensive water and sewage
systems, inadequate garbage collection and disposition and unstable urban environments that increase vulnerability to
natural disasters and jeopardize public health. It has therefore become imperative to redevelop and modernize the
decaying old core areas of the metropolis to make it more productive for business services. These indigenous areas need
up-to-date communications infrastructure, more efficient, office complexes and social services to improve the living

conditions of the inhabitants. The road network lacks packing spaces and good drainage system to the extent that
vehicles are parked along the indiscriminately in the night and during daylight when transacting business especially
around markets and business centers.
The incidence of poverty in the metropolis is manifested in the number of miscreants/area boys at various points like
Bere, Oke-Dada Idiarere and other areas of the city; these include homeless children in the garage and those sleeping
under the bridges. This however, is not prevalent in the rural area of Ibadan. These categories of people and others do
not have the opportunity to participate in society and in activities leading to improved health educational attainment,
personal security, and other benefits. Because of its ever-increasing population and inadequate drainage system, Ibadan
had suffered a lot from the problem of refuse disposal. This has resulted in blocking of the few existing drainage
consequent upon which Ibadan’s major river Kudeti and river Ogunpa and other smaller ones such as Ogbere stream,
Orogun stream and Labelabe stream had to overflow their banks. Historically, flood disaster is not a new phenomenon
in the history of Ibadan from 1902 to 1980 there were seven cases of flooding recorded (Tomori, 1979)
Sanitation Status: Sanitation provision in Ibadan is grossly deficient, as in most cities in sub-Saharan Africa: most
people do not have access to a hygienic toilet; large amounts of faecal waste are discharged to the environment without
adequate treatment; this is likely to have major impacts on infectious disease burden and quality of life (Hutton et al.
2007).
Challenges of evolution: Two of the most critical urban development issues facing Ibadan Metropolitan area and other
cities in Nigeria are fiscal and social realities. The financing of urban infrastructure and the institutional arrangement for
delivery of urban services; Ibadan does not currently have or follow any structural plan or master plan guiding the city
growth. There are recent indications that master plans for major cities and towns in Oyo State are being considered in
the year 2010 budget. Finally, Ibadan is drained by several rivers, the most popular of which is Ogunpa that has its
course right in the heart of the city. Some of these rivers, exasperated by deforestations in and around the city, annually
cause disastrous floods that result in the destruction of lives and property.
Urban Renewable: As a result of urban sprawl, the central city of Ibadan continues to deteriorate at much faster rate
than the sub-urban areas. There are no adequate urban rehabilitation programmes for coping with this situation. Even
the World Bank assisted Ibadan City Improvement Programmes (CIP) at communities like Yemetu, Mokola and
Ogbere-Agugu were inadequate for the task of stopping the deterioration around the city core areas because of the
inevitable disruption of the social and physical fabric of project areas and the failure to resolve conflicting goals.
Rehabilitation and maintenance of social infrastructure are neither frequent nor adequate even when available.
Not Encouraging the Adoption of Dangerous Solutions
In the past, the solution to the slum problem often amounted to one word: clearance. In hindsight, it is clear that
demolition often only added to the problem. The main achievement of slum clearance was to increase overcrowding
elsewhere. It did more to improve transport than to solve the housing problem. In practice, most observers have always
concluded that slum removal has had negative effects (Marris, 1960; Dwyer, 1975; Perlman, 1976; Valladares, 1978;
Rodríguez and Icaza, 1993: 68). Relocation disrupts existing commercial and social networks, lengthens the journey to
work, raises housing costs and generally disrupts people's lives. Fortunately, the validity of (Abrams, 1964) famous jibe
against slum demolition was gradually absorbed in many cities: In a housing famine there is nothing that slum clearance
can accomplish that cannot be done more efficiently by an earthquake. Demolition without replacement intensifies
overcrowding and increases shelter cost. By the 1970s, the World Bank among others was pushing the dual concept of
slum upgrading and sites and services (World Bank, 1974; 1980). Neither approach was perfect, but both represented a
huge improvement on either clearance or the pretence of building perfect homes for imperfect people (Werlin, 1999).
Let me emphasize that the (UN-Habitat, 2003b) is actively campaigning against it. Nevertheless, their wise advice to
upgrade settlements and avoid demolition is clearly being ignored by some governments. Meanwhile, more humane
approaches to the slum problem elsewhere are proving less than effective. In Colombia and South Africa, for example,
many poor people are being given subsidies to buy formal homes. However, not only is construction failing to keep up
with demand, but some of the beneficiaries have sold their new homes because they cannot afford to pay the associated
taxes and service charges (Huchzermeyer, 2003; Gilbert, 2004). New subsidized housing estates have arguably turned
into social housing ghettoes (Richards, 1995; Ducci, 1997).
In poorer environments, Turner (1976) points out, little purpose is served in providing a poor family with a fully
serviced, three-bedroom house if the family cannot afford the rent or mortgage payment. And this leads to another
myth: that improvement in housing can abate other, more fundamental inequalities. As such, Projects of slum clearance,
site and service schemes, and model housing are too marginal to influence substantially either the flow of investment or
the pattern of settlement and so, for the most part, are manipulated by the forces they seek to control. In cities with
abject poverty, housing improvements can be counterproductive insofar as the priorities of the desperately poor almost
always lie beyond shelter. Above all, the poor need to eat and to drink clean water. Overcrowding is clearly undesirable
but hunger is worse. Campaigns against poor housing are to be welcomed, but such campaigns have to demonstrate that

they can really improve living conditions. Improving shelter does not demand the end of ‘slums’, which is
unachievable, but to produce better housing conditions, which is.
6.0 Official Responses: Policies and Actions
Policies and programmes to eradicate or upgrade slums because of the growth of the city, the practice of planning and
managing cities in Nigeria has become progressively more demanding in terms of resources, organisation and skill.
Although the number and size of agencies responsible for generating policies and exerting powers in Nigerian cities
have grown over the years, there has not been a corresponding improvement in the quantity and the quality of urban
services rendered. According to (Egunjobi and Oladoja, 1987) not more than sixteen institutions directly involved in
decision making for the Ibadan Metropolitan Area, besides local governments, there were state agencies such as the
Town Planning Division of Oyo State Ministry of Local Government, Oyo State Property Development Corporation,
Oyo State Water Corporation and federal agencies such PHCN and Nigerian Telecommunications Limited. An
examination of the working of these agencies shows duplicity of functions and a lack of co-ordination among them
(Egunjobi and Oladoja 1987). This mismanagement affects the whole city rather than just the slums. The absence of
effective co-ordinating committees between these levels of government, have generally given rise to delays and
confusion in the execution of urban politics.
The multiplication of local governments within the city has had a direct effect on the management of slums: any project
for the renewal of the inner city, which is the biggest slum in Ibadan, requires the agreement of the five local
government chairmen. Lack of professional capacity, frequent bureaucratic changes and competition instead of
cooperation among the chairmen did not permit the governments to implement co-ordinated policies. Other reasons
should be advanced to explain the very limited impact of government policies on the development of slums in Ibadan.
On the one hand, most of the state governments in Nigeria have accorded very low priority to physical planning and
most of the states in the Federation have not given the urban centres the priority and the resources they need (Onibokun,
1998). Actually, the lack of funds is one of the main constraints that local governments have to face. This institutional
and financial framework has to be taken into consideration to understand why policies and programs have generally
failed for the improvement of slums in Ibadan city. A more detailed analysis must also be addressed to understanding
specific reasons of the failure for each case under consideration.
The Oyo State Urban Renewal Scheme, a World Bank Assisted Project: According to (Akinyode, 1998), the
Ibadan Metropolitan Planning Authority in collaboration with the Ministry of Lands and Housing of Oyo State decided
in 1988 to embark on the urban renewal of Ibadan. Actually, the project started earlier with a first pilot study
commissioned in 1984 by the World Bank to the Town Planning Division of the Ministry of Local Government of Oyo
State and called Upgrading of Core Areas: The major focus of the project was to improve various aspects of housing,
living and environmental conditions of different slums in Ibadan.
The Urban Basic Services (UBS) Programme: This is a programme of co-operation between the Federal Government
of Nigeria and UNICEF to tackle the problems of the urban poor especially women and children who are the mostly
deprived of urban basic services such as water, sanitation, health, educational facilities, employment and shelter (FGN-
UNICEF 1997). The programme contributes to the alleviation of urban poverty both in terms of income generation and
improved access to basic services, thus reducing the incidence of Children in Especially Difficult Circumstances. The
UBS programme activities were implemented in 72 slums and squatter communities including Ibadan, Lagos, Kaduna,
Onitsha and Port Harcourt. In Ibadan, UBS projects are currently going on in four communities in Ayeye and Agebni in
Ibadan North West Local Government and Mapo and Eleta in Ibadan South East Local Government (Wahab, 1998).
Multilateral Aid Programmes: The Sustainable Cities Programme (SCP) is a joint initiative of the United Nations
Centre for Human Settlements (Habitat) and the United Nations Environmental Programme (UNEP). It was launched in
August 1990, as part of the Urban Management Programme, in order to provide municipal authorities and their partners
in the public, private and community/popular sectors with improved abilities and capacities for environmental planning
and management (UNCHS 1996). Three priorities were identified: waste management, water supply and the
Institutionalisation of the Environmental Planning and Management (EPM). Various parts of the city were selected,
mainly at the outskirts. The objective of SIP was not to target specifically the slums of the city, but few parts of the city
included in the project could be regarded as slums (Bodija Market and its immediate residential neighbourhoods and the
southern outskirts of the city) (Adesanya 2000).
Community-Based and NGO-Based Programmes: The major objective of the Community Development
Associations is the development of the communities of origin (usually outside Ibadan). This finding is important and
demonstrates that people from the core area still have strong links with the countryside and that CDAs contribute by
way of payments of levies, contributions and donations to the provision of infrastructure such as roads, schools,
electricity and health facilities in their towns and villages of origin. The next most important CBOs in Ibadan are the co-
operatives which have funds for lending to members with a view to assisting members in their businesses or ventures,
purchasing goods in bulk and reselling to members.

The Oyo State Urban Renewal Schemes and the UBS Project: According to (Akinyode, 1998) the Oyo State Urban
Renewal Schemes allowed the renewal of the three selected areas (Mokola, Yemetu, Agugu) between 1988 and 1995.
The results for the three mentioned areas are as follows: though residential land use still takes the lion’s share of the
total land area, it has reduced in coverage to give room for the provision of new road construction, drainage,
infrastructural facilities and open space for recreation. Moreover, a majority of the people of the selected areas
estimated that the solid waste situation has improved during the past two years.
7.0 Combating the Challenges of Urban Slums in Ibadan City
According to (Alagbe & Adeboye, 2005), a squatter settlement which eventually leads to a slum is an inevitable
phenomenon on the landscape of every urban center. As long as Ibadan city continues to offer economic opportunities
such as salaried jobs, varieties of informal sector business enterprises, and the excitement of life, it will always continue
to attract migrants from rural and smaller urban areas into the city, leading to more squatting and eventually more
slums. The pertinent question is, how can the problem of slum development in Ibadan city be solved? Considering the
inevitability of squatting by urban poor, there is no “quick fix” solution to the problem of slum development. However,
the following suggested solutions will go a long way in providing succor to the problem of slum development.
Slum Upgrade: It is therefore suggested that instead of government and public authorities of state taking a
confrontational attitude of demolition threat, they should strive to create an enabling environment under which people,
using and generating their own resources, could find unique local solutions for their housing and shelter needs. This
conceptual approach is referred to as slum upgrade. The concept envisages a situation whereby The State Government
passes a bill through the State Assembly, urging inhabitants of identified slums within the State to upgrade their houses
to a minimum standard, as specified by the physical planning authorities within a window period ranging from 18-24
months. It should be emphasized that defaulters after the window period will have penalties as deemed fit by the
planning authority.
Sites-and-Services Schemes: The proliferation of slums and squatter settlements could be nipped in the bud simply by
improving the environmental quality of these areas and by government providing the basic necessary infrastructure.
This concept is known as the “sites-and-services schemes. (Srinivas, 2004b) defined “sites-and-services as the provision
of plots of land, either on ownership or land lease tenure, along with a bare minimum of essential infrastructure needed
for habitation”. The sites-and services scheme approach advocated the role of government agencies only in the
preparation of parcels or plots of land with certain basic infrastructure, which was to be sold outright to those that can
afford it or to be leased to other low-income beneficiaries. The basic infrastructures to be provided in a housing scheme
by the government apart from the plot of land are roads, water supply, drainage, electricity or a sanitary network. The
peculiarity of sites-and-services schemes which made it to be a workable and acceptable concept of housing provision
for the low-income class is that it adopts the same basic principle of the development of a squatter settlement but
without degenerating into slums. This is achieved by leaving the actual house building to the beneficiaries themselves to
use their own resources, such as informal finance or family labour and various other types of community participation
modes to build their own houses. Another feature of the sites-and-services scheme is that the beneficiaries could also
build their houses at their own pace, depending on the availability of financial and other resources.
Embracing Earth Building Technology: In keeping with (Alagbe & Adeboye, 2005) earth building technology should
be embraced and developed, to provide low-cost housing that are indeed affordable by the low-income earners and the
urban poor. Earth building technology involves the use of laterite and loamy soil that exist in abundant supply in all
parts of the city. Building with earth apart from been economical, has been proved to be strong and durable (Bolyn
Construction Company Ltd, 2010).
8.0 Recommendations
Financing urban infrastructure and services: The Nigerian government should identify, prioritize and initiate
sustainable infrastructural development and also leverage on private partnership and participation.
Natural disasters: In order to mitigate annual flooding, the town planning authorities should be proactive and stop
approving building plans on the flood-prone areas.
Public enlightenment: Geo-Knowledge should be advocated at all levels as this will improve the environmental
awareness of Ibadan people. Geographic Information Management Systems Government should be sensitized to utilize
the capabilities of the Geographic Information Systems in policy and decision making.
Partnership with the global community: It is essential that the city of Ibadan partner with identified communities
around the world where urbanization had initially posed problem to its growth and development but which the people
were able to come up with lasting solutions.

Government should not encourage the adoption of dangerous solutions and it is essential, for policy makers to
take advantage of Geographic Information technology to gather, analyse and manage information in order to identify,
prioritize and handle problems that emerge as a result of urban growth. There is no quick fix solution to the problem of
slum development but it could be nipped in the bud. One of such approaches is the slum upgrade option, which will
remove the confrontational attitude of government to squatting, and rather create an enabling environment under which
inhabitants of such settlements could use and generate their own resources, using unique local solutions to solve their
housing and shelter problems within a specified period.
