Effect of Urbanization on Land Use Land Cover in Gombe Metropolis (Published)

This study examined the integration of Remote Sensing and Geographic Information System (RS/GIS) for analyzing land use and land cover dynamics in Gombe Metropolitan, the Gombe State capital for the period 1976 to 2016. Land sat (TM) images of 1976, 1996and 2016 were used. The study employed supervised digital image classification method using Erdas Imagine 9.2 and Arc GIS 10.5 software and classified the land use into undisturbed vegetation, sparse vegetation, Settlements, Farmlands, Rock outcrops, Bare surfaces. The images were analyzed via georeferencing, image enhancement, image resampling and classification. The results obtained showan increasing settlements (from 0.36% – 4.01%) and farmlands (from 24.8% – 51.2%), over a decreasing of other LULC classes (bare surfaces, undisturbed and sparse vegetation, and rocky outcrops) for the time period of 1976 to 2016. These results could help city planners and policy makers to attain and sustain future urban development. It is therefore recommended that encouragement should be given to people to build towards the outskirts, like New mile 3 and Tumfure,etc through the provision of incentives and forces of attraction that is available at the city center in these areas to avoid the problem of overcrowdings.

Impact of Urbanization on Vegetation Cover in Gombe Metropolis and Environs (Published)

Demographic characteristics and economic development are the major determinants of urban shape and pattern of urbanization in Gombe which gave rise to rapid population growth. These determinants resulted to unplanned urban growth, unprecedented urbanization and land use change as a result contributing in the rapid reduction of vegetation cover and loss of arable land in the surrounding urban environment. The aim of this paper is on the impact of urbanization on vegetation cover. Both primary and secondary data was employed in this work. Socio-economic data and information on the status of tree species were gathered through questionnaire survey that involved 195 respondents using purposive sampling techniques in the study area. While the land use land cover analysis was carried out using ArcGis 10.5 and Edras Imagine 9.0. The finding was made to capture as accurate as possible six land use land cover classes as they changed through time. The result of the work shows a rapid decrease on the vegetation and a gradual increase in settlements between 1976 and 2016 due to the fact that Gombe metropolis became the capital of Gombe state in 1996. Also only few tree species were found within the study area, as most trees are cut down for various developmental purposes. The study recommends that urgent attention on conservation of vegetal resources within the metropolis should be encouraged.

Rural – Urban Migration of Working in the Elbasan, District of Albania (Published)

Most indicators of social – economic welfare  in Elbasan region show a duality that shows a big difference between rural – urban areas, for indicators such as: living standards including health, income and access of different types of employment. As a result of high rates of growth population  is noted involvement of young people entering every year in the labor force. In order to employ the large number of young people, able to work, Elbasan district should create hundreds of job opportunities every year for new entrants in the labor force. Considering the large number of new entrants in the labor force, entering every year is shown un unemployment rate . I have made my choice to realize my scientific research in the field of rural – urban migration. I ask partly growing academic interest in the study of internal migration in less developed countries.

Issues and Challenges of Urban Governance in Africa: The Nigerian Experience (Published)

The growth of urban centres has become one of the most remarkable trends of the 20th century Africa.  Mans’ inclination to agglomerate in large number in a few urban centres is quite impressive.  No wonder about 10 of the fastest growing cities in the world are found in Africa with an annual average growth rate of 3.5 percent and presently the fastest in the world. (UN World Urbanisation Prospect, 2014).  The urbanisation process is accelerate by the dynamisms of the socio-political and economic conditions of the contemporary times,  coupled with the increasing migration that takes place in Africa.  As the ever increasing urban population lead to proliferation of cities, certain environmental, legal, institutional and other problems arise resulting in ineffective urban governance.  This paper therefore examined the problem issues that have negative impacts on urban governance in Africa.  Eeffective urban governance is  to be understood from the perspective of Associative Network model.  Data was basically drawn from secondary sources.  Findings showed that effective urban governance hinges on efficient local government through synergy and collaboration of all stake holders, multi level government, public /private partnership, greater space for public participation etc.

Study on the Chemical and Biological Status of Malwatu Oya Basin, Anuradhapura in Sri Lanka. (Published)

Water pollution is a serious problem to the entire world. It threatens the health and wellbeing of humans, plants, and animals. With the advancement of communications and trade due to industrialization, accidental and purposive waste dumping, and uncontrolled use of water sources have contributed to the problem of water pollution in both surface water and the ground water. This study was mainly concerned with the evaluation of water quality of Malwathu Oya and its four basin tanks in the dry zone of Sri Lanka namely Nuwara wewa, Tissa wewa, Nachchaduwa wewa and Mahakanadarawe wewa in the Anuradhapura district using some selected water quality parameters. Malwathu Oya has been using as a source of drinking water for Anuradhapura. Eutrophication through the process of nutrient enrichment of stagnant waters due to urbanization & chemical added agricultural practices has been considered as the significant cause for water pollution in these areas. They cause algal blooms and release of toxic substances from species like cyanobacteria. Low Secchi Depth value and high chlorophyll a concentration indicate eutrophic nature of the Nuwarawewa and Tissawewa Lakes in dry periods. Malwathu oya too showed reasonably high Chlorophyll content during the same period. High nutrient loading was observed through the growth of phytoplankton species. Cylindrospermopsis raciborskii was the most dominant species recorded in the present study and Microcystis aeruginosa, Microcystis incerta, Pediastrum duplex. Merismo pediatenuissima, Melosira granulate and Diatomaelongata were also recorded from Nuwarawewa and Tissawewa during the study period. With respect to Physical and chemical parameters, very high turbidity, high nitrogen compounds ( Ammoinia, Nitrate, Nitrite), phosphate, total suspended solids, dissolved oxygen, chemical oxygen demand, biological oxygen demand were recorded in Nuwarawewa and Tissawewa due to the influence of human activities such as recreational , dumping wastes and agricultural practices. However data indicate that Nachchaduwa and Mahakandarawa lakes are well protected from above threats. At the same time Malwathuoya stream also showed the same kind of pollution pattern causing more critical situations for water treatment and water quality aspects. Therefore, an effective Lake Management and Lake monitoring programmes with integrated catchment management have to be adopted and it is a prior necessity in planning of the management practices of the catchments to get first hand information through this kind of research on these lakes.

The Nature of Peri-Urban Development in Lafia, Nasarawa State (Published)

This paper examines the characteristics of peri-urban areas in Lafia, a relatively new town by Nigeria’s account, but an important state capital, whose mineral resources, hospitality, administrative and educational status continue to drive its urban expansion. Peri urban areas in Lafia are by no means homogeneous, but area characterized by market-led medium density sporadic housing developments, lacking in basic infrastructure and facilities, employment opportunities and are poorly linked to the main town by transportation facilities. It is recommended that there is the need for more proactive involvement and intervention by various stakeholders in the management of peri urban areas to enhance their potentials and to address their peculiar problems.

URBAN HEAT ISLAND RESEARCH OF ENUGU URBAN: A REVIEW (Published)

Urbanization is a defining phenomenon of this century. Nigeria cities like the rest of the entire continent of Africa are rated high on this urbanization process. But one side effect of this process is urban heat island (UHI). The aim of this study is to present the results of all published papers considering UHI investigation of Enugu urban and propose activities that will develop UHI research in the future. Literatures were identified for review through a comprehensive search by using electronic and non-electronic databases. Related published literature and documents were searched in a systematic way using a range of key words relating to urban heat island. The literature review indicates that urban heat island effect exists in Enugu urban. The review also indicates that urban heat island research in Enugu city has been on the lowest ebb. The study concluded by advocating that the long-term and effective monitoring of UHI changes is possible with the application of an installed (wireless) monitoring network.

Housing the Urban Poor in Nigeria through Low-Cost Housing Schemes (Published)

This paper discusses a strategy and functional approach for the provision of low-cost housing for the urban poor in Nigeria. It notes the rapid rate of urbanization occurring in Nigeria, which is due mainly to massive rural-urban drift, and explosive urban population growth. A major consequence of this occurrence has been the deterioration of housing situation in the urban centres, manifested in severe shortages of housing units, and overcrowding in poor quality buildings that are situated in degraded environment. The urban poor constitute the vast majority of urban dwellers and they are in a disadvantaged economic position to build for themselves and are generally unable to make effective demand of existing housing. Housing this urban population is a major thrust of sustainable urban development. This paper asserts that a strategy for achieving the goal of adequately housing the urban poor is extensive mass housing development employing indigenous materials and methods, and involving the target population from policy making through programme execution. This is a bottom-up, participatory approach that will ensure the sustainability of the housing development. A case study, State Housing Estate, Oke-Ila, Ado-Ekiti, Nigeria in which indigenous materials were used in some buildings, was examined in the paper. The paper also looks at experiments with indigenous materials in the construction of model low-cost houses, and these include the Pampomani Housing Estate in Maiduguri, Borno state, Nigeria, and Yakatsari resettlement scheme in Kano, Nigeria. The paper examines earth architecture as a relevant indigenous technology and recommends its use in housing the teeming poor majority in Nigerian urban centres.

Analysis of Poverty Level Among Urban Households in Irewole Local Government Area of Osun State (Published)

Poverty is multi-dimensional. It is characterized by lack of purchasing power, exposure to risk, malnutrition, high mortality rate, low life expectancy, insufficient access to social and economic services and few opportunities for income generation. This study was carried out in Irewole local government area of Osun state to determine the level of poverty in the study area. The data collected were analyzed using descriptive statistics such as frequency distribution, percentage, regression and Foster, Greer and Thorbecke (FGT) model. A total of 120 copies of questionnaire were administered for collection of information from respondent.The results from the analyzed data indicated that most of the respondents were middle-aged with mean age of approximately 38years, about 75.2% of the respondents are married, 86.0% of them had formal education. The mean income of the respondents was analyzed to be #57,590.91 and the mean per capita is ₦12,625.441, the poverty line was also analyzed to be #8,416.96, the poverty incidence of 36.36 percent shows the percentage of those that fell below the poverty line, the poverty depth of 7.2 percent shows that the income of the respondents needs to be raised by that percentage to move out of poverty, and the severity is 2.79 percent which implies that poverty exist but not so severe in the study area. The study recommends that more effort and resources should be devoted to poverty reduction programmes. However, there is need for the government to formulate and implement policies that will provide employment, housing, education, improved health care facilities and other things specifically for the urban poor.
