Lake Chad (in French: Lac Tchad) is a large, shallow lake in Africa. It is economically very important, providing water to more than 20 million people living in the four countries which surround it — Chad, Cameroon, Niger and Nigeria. It is located mainly in the far west of Chad, bordering on north eastern Nigeria. The Chari River is its largest source of water, providing over 90% of Lake Chad's water. The lake possesses many small islands and mud banks, and its shorelines are largely...
CHAPTER ONEINTRODUCTION1.1 Background to the StudyContemporary globalization and urbanization is reproducing classic conditions historically associated with the emergence of infectious diseases and the periodically recurring pattern of epidemics and pandemics. The dynamics of contemporary globalization has contributed to various institutional gaps that make dealing with infectious diseases is increasing difficult and threaten concentrated human populations with p...
Abstract The study assessed the environmental implications of Gwagwalada rapid urbanization on health of residents. The study specifically examined health outcome of rapid urbanization on the different socio-economic class; the health outcome of rapid urbanization on water and sanitation; and on housing and residential occupation ratio. A total of 156respondents was drawn from planned, unplanned and rural Gwagwalada through random sampling techniques and simple percentage was used in...
Abstract River pollution in the urban areas is a common problem in many parts of Nigeria. This study examines the physio-chemical and biological parameters of the river Delimi within the Jos urban area. The specific objectives were to identify the dominant activities that constitute factors of pollution, and assess the pollution levels at different activity positions and different times of the year. Eight water samples were collected at eight locations on the river stretch...
The aim of this paper is to develop and test a theoretical and conceptual framework for an alternative approach to evaluation of public housing programmes in Nigeria. It seeks to address limitations of existing approaches where one theory or discipline has the upper hand in evaluating public housing programmes. This paper proposes a broad-based framework for assessing relationships be...
The aim of the project is the application of Geographic Information System in the effective management of Estate and its resources. While the objectives included capturing of geometric and attribute data about the estate features, such as road, parcel building, electric poles, wells, land use, ownership and address, design of a database for the estate, perform spatial analysis and product presentation. The geometric data acquisit...
ABSTRACT Urbanization causes urban expansion, dramatically transforming peri-urban environments and societies. In this process, rural lands are consumed by an expanding city, exploiting the large rent gap between agricultural and urban land. On the basis of the aforementioned reason, understanding peri-urban settlement growth is key to helping city managers develop strategies to curb undesirable development trends around the city’s periphery. To these ends, this study was under...
[ABSTRACTThe environment has been seen as human beings, fauna and flora; soil, water, air, climate and the landscape; the interaction between the factors mentioned in the first and second items; material assets and the cultural heritage. The Tropics are latitudinal locations 23°27' north to 23°27' south of the equator, within the earth's surface, over which the sun is almost directly overhead during the entire year. Environmental Hazards in the Tropics are those substances or actions ...
Limited resources, invested for the development of transport facilities, such as infrastructure and vehicles, coupled with the rapid rise in transport demand, existence of a huge number of no motorized vehicles on roads, lack of application of adequate and proper traffic management schemes are producing severe transport problems in almost all the urban areas of Nigeria. Worsening situation is the traffic congestion in the streets and sufferings of the inhabitants from vehicle emiss...
In the process of man’s consumption of natural resources in his natural environment, a number of stress is created which affects adversely the quality of the environment in which he lives. In this paper an attempt has been made to identify the various methods through which public awareness that are considered effective as well as the strategies for their implication are discussed in the light of the achievement of a sustainable environment in Nigeria. In its introductory section...
This paper examines factors influencing land ownership and real estate investment decisions in Ile-Ife. Investment property can be residential building, commercial building, factory and vacant land. The term investment property usually describes property that the owner does not occupy, but in some cases, the owner may occupy a portion of it. Although property in Ile-Ife may not be able to give a good income like their counterparts in Lagos or Abuja, but there are a number of factors whi...
It is projected that 25 million km of new paved roads will be developed globally by 2050—enough to encircle the planet more than 600 times. Roughly 90% of new roads will be built in developing nations, frequently in tropical and subtropical regions with high biodiversity and environmental values. Many developing nations are borrowing from international lenders or negotiating access to their natural resources in order to expand their transportation infrastructure. Given t...
Twenty-five years ago the Union of Concerned Scientists and more than 1,500 scientists, including the majority of living Nobel laureates in the sciences, penned the 1992 “Scientists’ Warning to Humanity.” These scientists called on humankind to curtail environmental destruction and cautioned “a great change in our stewardship of the Earth and the life on it is required, if vast human misery is to be avoided.” In their manifesto, they showed that humans are on a collision cour...
This study analyzed the spatiotemporal pattern of settlement expansion in Abuja,Nigeria, one ofWest Africa’s fastest developing cities, using geoinformation and ancillary datasets.Three epochs of Land-use Land-cover (LULC) maps for 1986, 2001 and 2014 were derived fromLandsat images using support vector machines (SVM). Accuracy assessment (AA) of the LULC mapsbased on the pixel count resulted in overall accuracy of 82%, 92% and 92%, while the AA derived fromthe error adjusted area (EAA) met...
The Cross River State Government in Nigeria is proposing to construct a ‘‘Cross River Superhighway’’ that would bisectcritical remaining areas of tropical rainforest in south eastern Nigeria. We offer and evaluate two alternative routes to the superhighway that would be less damaging to forests, protected areas, and biological diversity. The first alternative we identified avoids intact forests entirely while seeking to benefit agriculture and existing settlements. The secon...
