Abstract

In nature, erosion and deposition of sediments are at sites and at rates in a balance determined by the natural attributes of sources rocks and climatic factors. In recent times, however, constant anthropogenic activities in the sedimentary environment have greatly disturbed that equilibrium in many areas. The disappearance of Nwaorie River in Imo State, South-eastern Nigeria has prompted the authors to carry out the investigations presented in this paper. The described phenomenon can be attributed to filling up of the river bed by sediments eroded from the catchment and upstream areas. Therefore, an attempt has been made to show the relationships between population density, constructional, industrial and agricultural activities and soil erodibility. In a large view, intensive deforestation together with an equi-temporal intensification of agricultural activities range among the main factors responsible. In the presented case however, uncontrolled sand dredging activities in the downstream area of Nwaorie River contribute to the hazardous disturbance of the sedimentary equilibrium. Coincidently a rapid deterioration of surface-and ground-water quality can be observed in the observed hydro chemical parameters. The presented study is an example of environmental impacts caused by anthropogenic activities that is symptomatic for the extremely sensitive balance of nature especially in tropical and sub-tropical areas.

SOCIO-ECONOMIC IMPACT OF EROSION – INDUCED WATER POLLUTION ON SELECTED COMMUNITIES IN IMO AND ABIA STATE OF NIGERIA

Erosion Research Centre, Federal University Of Technology, P.M.B. 1526, Owerri Nigeria

Abstract

The paper examines the socio-economic impact of erosion influenced water pollution on eight communities in Imo and Abia States of Nigeria. These communities were selected because their major source of drinking water depended on four erosion prone Rivers; Njaba, Ikwu, Eme, and Imo. Data was collected using personal observation, individual and group interviews. One hundred and sixty respondents comprising of farmers, and other villagers participated in this study. Results show that 95% of the respondents perceived that pollution deprived them of their source of water for domestic uses. High turbidity of the rivers made them unsuitable for recreational activities such as swimming. It was also found that pollution caused dearth of fish during the study period. Results also show that flooding along the river banks lead to premature harvest of crops. The study further found that the cost incurred in buying water treatment chemicals by Water Boards increased by about 5%, coupled with additional cost of maintaining equipment which depreciated at an accelerated rate. The study concluded that erosion influenced water pollution has an adverse socio-economic impact on people in the eight communities and recommended appropriate control measures to check this problem.

SOIL EROSION AND WATER QUALITY MANAGEMENT IN AKWA IBOM STATE OF NIGERIA

UMOH, U.T

Department Of Geography, Federal University Of Technology, Minna

Abstract

Soil erosion occurs in several parts of Nigeria under different geologic, climatic and soil conditions. Akwa Ibom State, located at the southeastern corner of Nigeria, lying between latitudes 4033’ and 5033 north and longitudes 7025 and 8025’ east and experiencing humid tropical type of climate suffers from ravages of soil erosion at various locations. Soil erosion which has some hydrological consequences therefore calls for strategies of water quality management. Four sets of factors combine to cause soil erosion in Akwa Ibom State. Surface and groundwater quality are assessed as they are important component of the natural hydrological cycle which constitute major sources of water for multiplicity of uses. The erodibility of soils calculated by the monograph method was low and ranged between 0.017 to 0.075 t. ha. hr. ha-1 MJ-1 mm-1. In most locations, the product of low erodibility and high erossivity gave potential soil losses that ranged from 830 to 1900 t/ha//yr. Hydrological consequences of soil erosion include blocking of steam channels, variation of ground water level and drying up of streams. Available surface water supply sources are sampled, so also are some boreholes in the study area. Bacteriological, physical and chemical quality of the identified water sources were analyzed and found to be fair while some are hard. Possible pollution of ground and surface water are indicated and realistic treatment/management methods proffered.

THE RATE OF ADOPTION OF EROSION CONTROL MEASURES AMONG FARMERS IN S.E NIGERIA

Federal University of Technology, Owerri

Abstract

This study focussed on the rate of adoption of erosion control measures among farmers of Southeastern Nigeria. Data was collected from farmers from Orlu area of Imo State. Orlu erosion axis was selected because some erosion control packages such as alley cropping, contour bunding and planting across the slope have been introduced to farmers in the area. Findings show that the rate of adoption was 80%, while most of the technologies introduced to the farmers were adopted. Data analysis also showed that disseminating erosion control packages were most effective through the use of cooperative societies.

CITATION OF DR. SAMUEL CHIDI IWUJI:

THE SCHOOL OF HEALTH TECHNOLOGY LECTURE SERIES LECTURER

Dr Samuel C. Iwuji graduated from the biomedical programmes of the University of Port Harcourt and the University of Lagos, Nigeria where he obtained B.Sc. (Hons.), M.Sc. and PhD degree awards in Human Physiology / Pharmacology. He also had advanced professional training in Public Health; Environmental Health, Science Laboratory Technology and Biomedical Engineering. He is a Fellow, College of Biomedical Engineering and Technology of Nigeria. He is a member of the International Federation of Medical and Biological Engineering (IFMBE), Physiological Society, Environmental Health Officers of Nigeria, etc.

Under the driver of excellence, Prof. F.C. Eze as the substantive Vice-Chancellor of FUTO, Dr Iwuji was appointed the first Ag. Head, Department of Physiology (2016 - 2017) and in 2017, he was appointed the 4th Ag. HOD, Biomedical Technology. He among other achievements piloted the Department to achieve her first NUC’s full accreditation after 14 years of existence.

His visions have brought innovations that invigorated the culture of academic and administrative excellence in the Department. Consequently, in 2018, School of Health Technology under the motherly Deanship of Rev. Sr. Prof E.T. Oparaocha gave him the distinguished Merit Award of the School.
