Research Paper an Update on the Fish and Fisheries of Lake Oguta, Nigeria
Academia Journal of Environmetal Science 5(1): 013-021, January 2017 DOI: 10.15413/ajes.2017.0229 ISSN: ISSN 2315-778X ©2017 Academia Publishing Research Paper An update on the fish and fisheries of Lake Oguta, Nigeria Accepted 18th January, 2017 ABSTRACT The paper attempts to review the current trends in fisheries activities in Lake Oguta, Nigeria with the aim to finding a lasting solution to the declining fisheries of the Lake. Lake oguta is the largest standing freshwater body in South-Eastern Nigeria and is of immense importance to thousands of people in Oguta Local Government, Nigeria. The lake supports about 2, 403 full-time and 154 part-time fishers. About 80% of the fishers in the Lake obtain their protein from the Lake. Virtually, all the households in the Lake participates in fisheries activities from time to time. The fishers employ cast nets, gill nets, fish traps, seines, hooks and line etc most of which are locally made but increasingly, much of the gears are made locally using modern materials like nylon twine or rope in the case of gill nets. Recently, the fishers and fisheries of the Lake are faced with some challenges which include overfishing, pollution, eutrophication, aquatic weeds, decline in fish biodiversity, illegal, unreported and unregulated fishing, ineffective monitoring, control and surveillance (MCS) and poverty, lack of alternative livelihoods and inadequate social legislation as well as, some destructive fishing methods. The free access to the resources of the lake has caused the resources to be biologically and Sanda MK, Kwaji BP, Ajijola KO, economically overfished. -
A Case Study of the Oguta Lake Watershed, Niger Delta Basin, Nigeria
American International Journal of Contemporary Research Vol. 2 No. 7; July 2012 An Assessment of the Physical and Environmental Aspects of a Tropical Lake: A Case Study of the Oguta Lake Watershed, Niger Delta Basin, Nigeria Ahiarakwem, C. A. Nwankwor, G.I. Onyekuru, S.O. Department of Geosciences Federal University of Technology Nigeria Idoko, M. A. Department of Geography and Regional Planning University of Calabar Calabar, Nigeria Abstract The assessment of very important physical and environmental aspects of Oguta Lake and its watershed, Niger Delta Basin was carried out using data obtained from satellite imagery (Landsat Tm 2000) and the Global Positioning System (GPS). The data were analysed and interpreted using the Integrated Land and Water Information System (ILWIS) and AutoCAD Land developer. False Colour Composite (FCC) map generated from the satellite imagery displayed the study area into portions covered by vegetation as red; built-up areas around the lake as cyan; areas covered by sediments as blue/cyan and eutrophication, pale red. Digitalization/processing of the FCC map indicated that areas covered by the Oguta Lake water body is about 1,870.4m2 (68.2%) while degraded portions of the lake occupied an area of 1152.25m2 (38.8%). The degraded portions of the lake is comprised of areas under intense environmental stress arising from anthropogenic activities (degradable portion) with a total area of 1099.97m (36.91%), areas covered by sediments and eutrophication with total areas of 41.3 m2 (1.39%) and 14.9m2 (0.5%), respectively. The study also showed that built-up areas outside the vicinity of the lake with an area of about 4,983.3m2 have very strong positive correlation (R2=1) with the degradable portions (areas characterized by human activities such as washing, bathing and sand mining) of the lake. -
Hydrogeophysical Evaluation of Aquifer of the Lower Orashi River
International Journal of Advanced Academic Research | Sciences, Technology and Engineering | ISSN: 2488-9849 Vol. 5, Issue 8 (August 2019) HYDROGEOPHYSICAL EVALUATION OF AQUIFER UNITS AROUND THE LOWER ORASHI RIVER AREA, SOUTHEASTERN NIGERIA 1MBAGWU E.C., 1IBENEME S.I., 1OKEREKE C.N AND 1EZEBUNANWA A.C. 1Department of Geology, Federal University of Technology Owerri, Imo State, Nigeria. Corresponding Authors: [email protected], [email protected] ABSTRACT Hydrogeophysical characteristics of the aquifers of the Lower Orashi River Area, Southeastern Nigeria was done using VES to delineate the aquifers and evaluate their geometric characteristics. The study area is underlain by the Ameki, Ogwashi and Benin Formations. The unconsolidated nature of the Formations and their high susceptibility to contamination have made this study imperative, as it would assist water resource planners and developers in the area to understand the best way to plan and site boreholes in the area. Eighty eight (88) Schlumberger Vertical Electrical Soundings (VES) were carried out in various parts of the study area with a maximum electrode separation (AB/2) of 350 m. The VES data were processed using a combination of curve matching techniques and computer iterative modeling. The study revealed seven to ten geo-electric layers with varying lithologies majorly sand units and a multiple aquifer system ranging from confined to unconfined aquifers. The results indicate that aquifer thickness ranges from 20m to about 227m. A quantitative interpretation of the curves -
Petro-Violence and the Geography of Conflict in Nigeria's
Spaces of Insurgency: Petro-Violence and the Geography of Conflict in Nigeria’s Niger Delta By Elias Edise Courson A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Geography in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Michael J. Watts, Chair Professor Ugo G. Nwokeji Professor Jake G. Kosek Spring 2016 Spaces of Insurgency: Petro-Violence and the Geography of Conflict in Nigeria’s Niger Delta © 2016 Elias Edise Courson Abstract Spaces of Insurgency: Petro-Violence and the Geography of Conflict in Nigeria’s Niger Delta by Elias Edise Courson Doctor of Philosophy in Geography University of California, Berkeley Professor Michael J. Watts, Chair This work challenges the widely held controversial “greed and grievance” (resource curse) narrative by drawing critical insights about conflicts in the Niger Delta. The Niger Delta region of Nigeria has attracted substantial scholarly attention in view of the paradox of poverty and violence amidst abundant natural resources. This discourse suggests that persistent resource- induced conflicts in the region derive from either greed or grievance. Instead, the present work draws inspiration from the political geography of the Niger Delta, and puts the physical area at the center of its analysis. The understanding that the past and present history of a people is etched in their socio-political geography inspires this focus. Whereas existing literatures engages with the Niger Delta as a monolithic domain, my study takes a more nuanced approach, which recognizes a multiplicity of layers mostly defined by socio-geographical peculiarities of different parts of the region and specificity of conflicts its people experience. -

I., Ledogo, Bright E. Department of Physics University of Port Harcourt, Nigeria E-mail: [email protected] Abstract Twenty vertical electrical soundings (VES) were carried out in Ideato North and South areas of Imo State to delineate subsurface stratification and groundwater occurrence. Field data were acquired using Ohmega- 500 resistivity meter. The Schlumberger electrode configuration and maximum electrode spread of 900m were used. The data were interpreted using the Advanced Geosciences Incorporation (AGI) ID software and the Schlumberger automatic analysis version. Interpretative geoelectric cross-sections constructed along three profile lines delineated the subsurface stratification. The sediments consist of sequence of shale, sandstone, siltstone and clay. Around Dikenafai in Ideato-South the geology tended towards the Benin Formation. Ideato- North is more shaly than Ideato-South. Groundwater was delineated within the zone interpreted to be fractured shale with aquifer materials composed of sand, sandstone and clay sandstone and resistivity ranging from 0.10Ωm recorded at Urualla to 1035Ωm observed at Obodoukwu. Depth to water table is quite high and varied from 71.90m to 138.32m. Aquifer thickness varied across the study area with high values at Obodoukwu, Ndiadumora and Dikenafai. These areas are good prospects for groundwater development. Analysis of pumping test and VES data led to estimation of aquifer parameters for the study area. -

Ibeje Department of Civil Engineering, Imo State University, Owerri, Nigeria [email protected] Submitted: 05-MAR-2020; Reviewed: 23-MAR-2020; Accepted: 31-MAR-2020 Abstract- Knowledge of hydraulic properties of groundwater aids economic and environmentally friendly exploitation of water resources in water-scare rural area such as Okija. In this study therefore, the aquifer constants are evaluated for Okija town in Ihiala Local Government Area of Anambra State, Nigeria to facilitate efficient and effective exploitation of the water resources in the area. The drawdown test involved pumping down the water level and monitoring the response of hydraulic head in the surrounding aquifer. The computation of formation constants is performed in three ways: Theis method, Cooper-Jacob method and Chow method. Model Selection Criterion (MSC was used to evaluate the discharge predictions from the three methods. The results show that transmissivity and storage coefficient for Theis method are 256. 37 m2/day and 146.67 m2/day; Cooper-Jacob method are 251.71 m2/day and 131 m2/day, and chow method are 2 67.87 m2/day and 146.67 m2/day respectively. This work represents a practical and novel approach to the determination of a key hydrogeological parameter for a highly transmissive aquifer. -
Analysis and Characterization of Njaba River Gully Erosion, Southeastern Nigeria: Deductions from Surface Geophysical Data
Australian Journal of Basic and Applied Sciences, 6(4): 122-128, 2012 ISSN 1991-8178 Analysis and Characterization of Njaba River Gully Erosion, Southeastern Nigeria: Deductions from Surface Geophysical Data. ONU, Nath. N. and OPARA, Alexander. I. Department of Geology, Federal University of Technology PMB 1526 Owerri, Nigeria. Abstract: A detailed geophysical survey was carried out at the Njaba River gully erosion site at Awo- Omamma, southeastern Nigeria using the electrical resistivity vertical and azimuthal sounding techniques as well as the self potential method. The objective of the study was to evaluate the subsurface structure at the gully site and adjacent areas and to offer geological/ geophysical explanation on the cause of the sudden landslide that occurred at the site recently. Results of the study revealed that the azimuths of the major axes of the anisotropy diagrams correlate significantly with the strikes of the geological formations with the coefficient of anisotropy varying from 1.30 to 1.70, indicating that structural in-homogeneities exist. The evidence spontaneous potential data indicated that the strike of the gully which is oriented in the NW-SE direction is characterized by low SP values ranging from -50 to -100mV; and low electrical resistivity values both flanked by a zone of higher SP and resistivity values. Similarly, it was also revealed that the maximum electrical anisotropic effect was detected in the NW-SE direction and this coincided with the regional trend of the study area. Consistent NW-SE orientation of maximum axis of electrical anisotropy and the attitude of the gully eliminated the wide range of other possible causes and suggest that the gully is structurally controlled and may be running along the geologic contact between the Benin and the Ogwashi/Asaba Formations.
