No full textSAFETY AND DISTRESS RESPONSE SYSTEM IN NIGERIA‘S INTERNATIONAL AIRPORTS
No full textA THESIS IN THE DEPARTMENT OF GEOGRAPHY SUBMITTED TO THE FACULTY OF THE SOCIAL SCIENCES IN PARTIAL FULFILLMENT OF THE REQUIREMENT FOR THE AWARD OF DEGREE OF
DOCTOR OF PHILOSOPHY OF THE UNIVERSITY OF IBADAN.Airports require complete safety initiatives with a maximum of 20 minutes response time
to distress situation. They are therefore regulated by International Civil Aviation
Organisation (ICAO) standards. However, in Nigeria, airport safety and distress response
have been of great concern due to inadequate infrastructure. This study, therefore,
examined safety facilities and response capability to distress situations in Nigeria
international airports. The effects of haphazard spatial developments within the airports
and their environments were also examined.
The available infrastructure for safety and distress response initiatives were considered
using ICAO check-list to determine their adequacy. Four international airports namely:
Murtala Muhammed (Lagos), Aminu Kano (Kano), Nnamdi Azikwe (Abuja), and Port
Harcourt were purposively selected. Three questionnaires were administered to 618
airport operators, 369 users and 462 neighbours in soliciting information on various
aspects of safety and distress response initiatives including terminal buildings,
navigational aids, runways and fire-fighting equipment and adequacy of staff training for
operating Safety Management Systems (SMS) effectively. This was complemented with
Key Informant Interview (KII) with 12 technical staff from 5 airport operators. Satellite
imagery data were used to acquire spatial information on the airports. Descriptive
statistics were used to analyse data on adequacy of safety facilities, staff training and
distress responsiveness. Pearson correlation was used to determine the relationship
between safety infrastructure and airport age. Analysis of Variance was used to
determine variations in airport operators‘ safety awareness as recommended by ICAO.
The KII data were content analysed, while raster model was used to determine the landuse
pattern. Analysis were done at p<0.05.
Functionality of safety facilities fell short of ICAO standards in all the airports by 30%,
25%, 20% and 10% in Lagos, Kano, Port-Harcourt and Abuja respectively. A positive
relationship existed between airport age and obsolescence of safety infrastructure
(r=0.12). Lagos airport had the most obsolete safety facilities. KII also revealed
breakdown of infrastructure in the airports. There were significant variations in safety
awareness among airport operators (F=11.95). Safety awareness was highest among the
staff of Federal Airports Authority of Nigeria (34.9%) and lowest among airport
handling agents (12.2%). Ninety-one percent of airport operators sampled indicated
distress response as being poor. Response time varied from 30 minutes in Abuja to 54
minutes in Lagos. Sixty percent of the users considered airport service quality as very
low. Forty-six percent of airport operators indicated that they had no training since
employed. Spatial analysis of the airports and their environment showed that Lagos and
Kano airports suffered safety threats from poor waste management and chaotic traffic
patterns.
Safety and distress response capacity was relatively low in all the international airports
investigated. There is an urgent need for the airports to be managed in line with
international standards. Staff training should also be prioritised and spatial developments
around airport s need to be controlled.

Design, construction and evaluation of a meteorological mobile mast
No full textA 30 metre meteorological mobile mast has been designed and constructed for upper air profile measurements. The parameters to be measured are wind speed, wind direction, temperature and relative humidity. The sensors for each parameter to be measured are constructed with locally available materials. The mechanical mast is designed in such a way that it can be collapsed like the electronic - controlled car radio antenna. It is made up of steel pipes of different diameters driven manually or by an electric motor via a pulley system. The sensors were calibrated with standard instruments and attached to different height of the mast for sample data acquisition. Data obtained from the sensors are stored in a data logger at the base of the mast. The data obtained were analyzed and there are appreciable correlations between the standard and the constructed instruments.Keywords: Instrumented, Meteorological, Mast, Profile, Measurement
Spatial Analysis of Rainfall in the Climatic Regions of Nigeria using Insitu Data
No full textAnalysis of rainfall trends is important in studying the impart of climate change for water resources planning and management. In this paper, the daily rainfall data of thirty-two (32) years (1982 - 2013) were obtained from the Nigeria Meteorological Agency (NIMET), Oshodi, Lagos for some stations across the climatic regions of Nigeria and these stations were further divided into four climatic regions according to their weather conditions such as Sahel savannah, Derived Savannah, Guinea Savannah and coastal regions. The rainfall pattern as well as its spatial distribution with air temperature through different months and years were observed and studied. The long time average of monthly and annual amounts of rainfall was calculated and analyzed. It was observed in the years of study statistically that highest mean rainfall of 193.38mm occurred in August at Sahel region, 215.99mm and 214.87mm in September at Guinea and Derived savannah regions respectively and 310.19mm in July at Coastal regions. Meanwhile, the average annual rainfall includes 590.831mm in Sahel, 1220.941mm in Guinea Savannah, 1381mm in Derived savannah and 1532mm in Coastal. It was observed that rainfall pattern below latitude is bi-modal in distribution having a primary peak in June-July and another secondary peak in September with little dryness in August. Finally, there is an increasing trend in rainfall amounts and frequency towards the middle of the wet season in all the regions in Nigeria.

Spatio-Temporal Variability of Water Vapour Density over Nigeria using CM SAF Data
No full textWater vapour plays a major role in atmospheric processes but remains difficult to quantify due to its high variability in time and space and the sparse set of available measurements. Atmospheric Data from the Department of Satellite Application Facility on Climate Monitoring, Germany, have been used to derive and extensively study water vapour density at five different atmospheric levels for twenty six stations grouped into four climatic regions [coastal, guinea savannah, midland and sub sahelian regions] over Nigeria for the period of four years. Seasonal, columnar and spatial variability with monthly height profile were deduced and observed. The values of water vapour density at low level and mid-level was low and highly vary at the midland and sub sahelian regions compared with the coastal and guinea savannah regions. It was observed that the seasonal and spatial variations of water vapour density depend on geographical location, time, altitude and atmospheric pressure level.

Differences in Sexual Practices, Sexual Behavior and HIV Risk Profile between Adolescents and Young Persons in Rural and Urban Nigeria.
No full textWe aimed to determine differences in sexual practices, HIV sexual risk behaviors, and HIV risk profile of adolescents and young persons' in rural and urban Nigeria.We recruited 772 participants 15 to 24 years old from urban and rural townships in Nigeria through a household survey. Information on participants' socio-demographic profile (age sex, residential area, number of meals taken per day), sexual practices (vagina, oral and anal sex; heterosexual and homosexual sex; sex with spouse, casual acquaintances, boy/girlfriend and commercial sex workers), sexual behavior (age of sexual debut, use of condom, multiple sex partners, transactional sex and age of sexual partner), and other HIV risk factors (use of alcohol and psychoactive substances, reason for sexual debut, knowledge of HIV prevention and HIV transmission, report of STI symptoms) were collected through an interviewer administered questionnaire. Differences in sexual behavior and sexual practices of adolescents and HIV risk profile of adolescents and young persons resident in urban and rural areas were determined.More than half (53.5%) of the respondents were sexually active, with more residing in the rural than urban areas (64.9% vs 44.1%; p<0.001) and more resident in the rural area reporting having more than one sexual partner (29.5% vs 20.4%; p = 0.04). Also, 97.3% of sexually active respondents reported having vaginal sex, 8.7% reported oral sex and 1.9% reported anal sex. More male than female respondents in the urban area used condoms during the last vaginal sexual intercourse (69.1% vs 51.9%; p = 0.02), and reported sex with casual partners (7.0% vs 15.3%; p = 0.007). More female than male respondents residing in the rural area engaged in transactional sex (1.0% vs 6.7%; p = 0.005). More females than males in both rural (3.6% vs 10.2%; p = 0.04) and urban (4.7% vs 26.6%; p<0.001) areas self-reported a history of discharge. More females than males in both rural (1.4% vs 17.0%; p = 0.04) and urban (15.0% vs 29.1%; p<0.001) areas self-reported a history of itching.There are differences in the sexual behavior and practices of adolescents and young persons' residing in the urban and rural area with implication for HIV prevention programming
