  • The Evolution of Ibadan As the Largest Metropolitan Area in Nigeria
    THE EVOLUTION OF IBADAN AS THE LARGEST METROPOLITAN AREA IN NIGERIA By: ESV. TOMORI M.A. anivs, rsv. mnim MD/CEO Macos Urban Management Consultants E-mail: [email protected] ` Established For Urban Management Capacity Building and Good Governance 1.0 URBAN TRANSFORMATION HISTORY 1.1 Introduction Urbanization and city creation predates colonialism in many African countries. Apart from Egypt, where urban civilization dates back to 5,000 years, several cities in other African regions have centuries old Histories. Early urban development has been recorded during the Sudanese Empire of 800A.D. the Mali Empire of 1500A.D. and Songhai Empire of 1800A.D. These important historical artifacts, the cities, flourished as a result of their location along the trans-Sahara trade routes, emphasizing their importance as catalysts in socio-economic inter-relationships. Powerful local rulers enhanced the evolution of these early cities into effective nodes of human development and as engines of economic and social growth. Some of the prominent ancient pre-colonial cities of the region include: Bamako, Gao, Timbuktu, Ouagadougou, Agades, Begho, Benin, Ibadan, Ile-Ife, Ilorin, Kumasi and Oyo. The implications of urbanization are not appreciable from demographic numbers alone (World Bank in Cities in Transition, 2013). The urban transformation affects the physical concentration of people, patterns of land use, social structures and interactions, and the nature and scale of economic production. Each of these dimensions of change affects the lives of individuals and the requirements for resources and governance. This urbanization creates significant opportunities for national development, and for reducing poverty for all citizens. But realizing the potential gains from the urban transition depends on how well cities and towns manage growth and meet the challenges of providing responsive governance and ensuring services for all firms and households.

  • Treatment of Childhood Diarrhoea in Nigeria: Need for Adaptation of Health Policy and Programmes to Cultural Norms
    TreatmentJ HEALTH patterns POPUL of NUTR diarrhoea 2000 in Dec;18(3):139-144 Ibadan, Nigeria © 2000 ICDDR,B: Centre for Health and Population Research139 ISSN 1606-0997 $ 5.00+0.20 Treatment of Childhood Diarrhoea in Nigeria: Need for Adaptation of Health Policy and Programmes to Cultural Norms Olayemi O. Omotade1, Adebowale A. Adeyemo2, Clara M. Kayode1, and Oladimeji Oladepo3 1Institute of Child Health, University College Hospital, 2Department of Paediatrics, and 3Department of Preventive and Social Medicine, College of Medicine, University of Ibadan, Ibadan, Nigeria ABSTRACT A community survey of treatment regimens for acute diarrhoea in children was carried out in 10 villages in the Ona Ara Local Government Area of Oyo State, Nigeria, using a combination of qualitative (focus-group discussions) and quantitative (weekly surveillance of diarrhoea) methods. Focus-group discussions were conducted with parents of children aged less than 5 years, while a surveillance of diarrhoea among 550 children of same age was carried out during a 6-month period. The findings of the study showed that not all types of diarrhoea were recognized as illnesses, and only those considered to be illnesses were treated. Treatment often involved an adhoc group which comprised adults who were present at the time the illness occurred (including parents, neighbours, relatives, and elders). Certain beliefs and practices, such as associating types of diarrhoea with occupation or ethnic groups, categorizing the severity on perceived causes, and withholding certain foods during episodes of diarrhoea, were common factors in decision-making for seeking treatment. Antimicrobial agents were used in the case of 46.8% of 205 diarrhoeal episodes, and 28.5% were not at all treated.

Oyo State is noted for abundant surface water and appreciable groundwater resources in its pockets of regolith aquifers; as it has about eight months of rainy season and a relatively deep weathered regolith. In spite of this, cases of water associated diseases Copyright© IAARR 2014: www.afrrevjo.net 51 Indexed and Listed in AJOL, ARRONET AFRREV STECH, Vol. 3(2) May, 2014 and deaths have been reported in the rural areas of the state. This study attempts to conduct an investigation into accessibility to potable water in the rural areas of Oyo State, Nigeria via the component approach of water poverty index (WPI). Multistage method of sampling was applied to select 5 rural communities from 25 rural LGAs out of the 33 LGAs in the State. Data were collected through the administration of 1,250 copies of questionnaire across 125 rural communities. Component Index method as developed by Sullivan, et al (2003) was modified and used in this study.

Thus a sample each of underground water was collected from each of the selected 5 rural communities in each of the selected 25 out of the 33 LGAs in Oyo State for the purpose of quality assessments. Eleven (11) + parameters namely water temperature (°C), pH, electr ical conductivity (EC), Sodium (Na ), SO 4, + Potassium (K ), Nitrate (NO 3), Phosphate (PO 3), coli-form count, Oxidation Redox Potential (ORP) and Total Dissolved Solids (TDS) were subjected to standard laboratory analysis.

    ７．Results of Geophysical Survey 1. General 1-1 Purpose of Geophysical Survey The purpose of the geophysical survey is to find the promising communities with high potential ground water development. 1-2 Contents of geophysical survey -1st Stage (BD1) The geophysical survey was conducted in 100 communities of high priority selected among 220 communities -2nd stage（BD2） 56 communities among 100 communities were analyzed as low potential water development in 1st stage. The geophysical re-survey conducted at these 56 communities and in the new 17 additional communities. Total of geophysical survey including re-survey is 117communities (173 sites). ① Electromagnetic Survey ・Method ：Loop-Loop (Srigram) ・Line ：more than200 ｍ（5 ｍ interval） ・Equipment ：GEONICS EM34 ・Analysis ：Horizontal Electric Conductivity Profiling ② Resistivity Survey ・Method ：Schlumberger method ・Survey depth：a=100m ・Equipment ：ABEM SAS300B ・Analysis ：1dimention inversion 2. Result of survey 2-1 Potential of Ground Water Basement of survey area is composed with crystal formation (Granite, Gneiss) in Precambrian Period. Upper stratum is weathered. According to the situation of weathered zone, crack and fault in crystal rock (Granite, Gneiss), the formation of aquifer is not constant due to thickness of weathered zone and scale of crack etc. Formation of aquifer are as follow: ・ It is difficult to find aquifer in fissure zone ・ Main aquifer from the test boreholes are located in the boundary between weathered zone and basement. ・ The thickness of weathered zone needs to be more than 20m for high potential of water development ・ Based on the electric conductivity and existing data, the resistivity of weathered zone needs to be less than 130 ohm-m.

  • Gamma Radioactivity Levels and Their Corresponding External Exposure of Soil Samples from Tantalite Mining Areas in Oke-Ogun, South-Western Nigeria
    Radioprotection 2012 DOI: 10.1051/radiopro/2012003 Vol. 47, n° 2, pages 243 à 252 Article Gamma radioactivity levels and their corresponding external exposure of soil samples from tantalite mining areas in Oke-Ogun, South-Western Nigeria A.K. ADEMOLA1, R.I. OBED2 (Manuscript received 9 September 2011, accepted 16 January 2012) Abstract The radioactivity concentrations of 226Ra, 232Th and 40K were measured using gamma-ray spectroscopy with NaI (Tl) detectors in four tantalite mining sites in the Oke-Ogun area, South-Western Nigeria. The measured values of the activities of 40K, 226Ra and 232Th in the soil samples were found to lie in the ranges 123.7 ± 3.8 – 1372.3 ± 8.6, 16.8 ± 1.6 – 71.1 ± 2.53 and 3.0 ± 0.7 – 31.9 ± 1.0 Bq kg–1, respectively. These samples were also found to have radium equivalent activity in the range 74.2–121.0 Bq kg-1. Values of 0.2–0.3 for the external and 0.3–0.4 for the internal hazard indices were estimated for the samples and the annual effective dose varied from 70.3 ± 13.5 to 100.8 ± 42.8 µSv with a mean of 87.5 ± 18.6 µSv y–1. The annual effective dose is higher than the world average. Keywords: Oke-Ogun / radionuclide / tantalite / natural radioactivity / effective dose 1. Introduction Human beings are exposed to background radiation that stems from both natural and man-made sources. Natural background radiation, which is equivalent to 2.4 mSv per person, makes up approximately 80% of the total radiation to which a person is exposed during one year (IAEA, 1996).
