POLLUTION STATUS OF THE URBAN SECTION OF DELIMI RIVER.HYDROLOGICAL SOCIETY(1)

 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...

Evaluation of Public Housing Programmes in Nigeria: A Theoritical and Conceptual Approach

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...

Application of GIS in Estate Management (A Case Study of Araromi Phase IV, Oyo. Nigeria)

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...

Peri-urban Settlements and Sustainable Land Management in Port Harcourt, Nigeria

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...

ENVIRONMENTAL HAZARDS IN THE TROPICS

[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 ...

THE CONTRIBUTIONS OF ROAD TRANSPORT TO ENVIRONMENTAL POLLUTION IN OWO, ONDO STATE, NIGERIA.

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...

STRATEGIES FOR CREATING PUBLIC AWARENESS FOR ENVIRONMENTAL SUSTAINABILITY IN NIGERIA

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.

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...

Economic, Socio-Political and Environmental Risks of Road Development in the Tropics

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...

World Scientists Warning to Humanity- A Second Notice

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...

Analysis of Settlement Expansion and Urban Growth Modelling Using Geoinformation for Assessing Potential Impacts of Urbanization on Climate in Abuja City, Nigeria

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...

Alternative Routes for a Proposed Nigerian Superhighway to Limit Damage to Rare Ecosystems and Wildlife

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...

SPATIAL ANALYSIS FROM REMOTELY SENSED OBSERVATIONS OF CONGO BASIN OF EAST AFRICAN HIGH LAND TO DRAIN WATER USING GRAVITY FOR SUSTAINABLE MANAGEMENT OF LOW LAYING CHAD BASIN OF CENTRAL AFRICA

The Chad basin which covers an area of about 2.4 million kilometer square is one of the largest drainage basins in Africa in the centre of Lake Chad .This basin was formed as a result of rifting and drifting episode, as such it has no outlet to the oceans or seas. It contains large area of desert from the north to the west. The basin covers in part seven countries such as Chad, Nigeria, Central African Republic, Cameroun, Niger, Sudan and Algeria .it is named Chad basin because 43.9% falls...

THE EFFECTS OF TAX EVASION AND AVOIDANCE ON SUSTAINABLE INFRASTRUCTURAL DEVELOPMENT IN ADO-ODO OTA LGA OF OGUN STATE

Sustainable infrastructural development as a key ingredient for sustained economic growth has thus far received poor attention in Ado-Odo Ota local government area. The intense shortage of infrastructure constitutes a huge threat to survival in the study area. Despite the efforts made to enhance this “Social Overhead Capital”, it still currently does not meet the requirement of economic development. The study emphasizes on the extent the tax irregularities hinder sustainable infrastr...
