  • SIGNIFICANCE of ANIMAL MOTIFS in INDIGENOUS ULI BODY and WALL PAINTINGS Nkiruka Jane Uju Nwafor Department of Fine and Applied A
    Mgbakoigba, Journal of African Studies. Vol. 8, No. 1. June 2019 SIGNIFICANCE OF ANIMAL MOTIFS IN INDIGENOUS ULI BODY AND WALL PAINTINGS… Nkiruka Jane Uju Nwafor SIGNIFICANCE OF ANIMAL MOTIFS IN INDIGENOUS ULI BODY AND WALL PAINTINGS Nkiruka Jane Uju Nwafor Department of Fine and Applied Arts Nnamdi Azikiwe University, Awka. [email protected] This article explores the significance of animal motifs in traditional Uli body and wall paintings. A critical assessment and understanding of the philosophical import of animals in African concept of existence is vital for an in-depth appreciation of their (animals’) symbols in indigenous African artworks. This paper attempts to a draw parallel between traditional beliefs concerning certain animals among the Igbo of south-eastern Nigeria and motifs derived from indigenous Uli body and wall painting. In essence, the article sees animal motifs in Uli body and wall paintings as playing an aesthetic as well as metaphysical roles. Hence I argue that local nuances of religiosity and spirituality have historically imbued the animals with a heightened sense of sacredness in some Igbo communities thus allowing the animals to occupy a mystical space in Igbo cosmology. Introduction The pre-colonial system of knowledge transmission in Africa was not only through oral literature but also through the varied artistic traditions that survived from one generation to the other. The rich heritage of ancient Egyptian arts (including the hieroglyphs), the numerous Neolithic rock paintings and engravings found in Northern Africa, which dates back to 5000 and 2000 BCE respectively were mainly symbolic of vital occurrences of the past, documented through art (Getlein 2002: 335).

Yet, evidence Overall description of research area abounds showing that the traditional food base and knowledge of Indigenous Peoples are being eroded. This has resulted in the use of fewer species, decreased dietary diversity due wo communities were randomly to household food insecurity and consequently poor health sampled in each of four states: status.

  • Affixes and Tone in Aguata Igbo: a Critical Appraisal
    IOSR Journal Of Humanities And Social Science (IOSR-JHSS) Volume 22, Issue 6, Ver.12 (June. 2017) PP 27-33 e-ISSN: 2279-0837, p-ISSN: 2279-0845. www.iosrjournals.org Affixes and Tone in Aguata Igbo: A Critical Appraisal Chinwe E. Obianika Department of Linguistics and Literary Studies, Ebonyi State University, Abakaliki. Abstract: This work sets out to investigate the behavior of tone in the affixes involved in the formation of three aspects in Aguata Igbo. The dialect group comprises of three main dialects; Amaiyi, Orumba and Aguata. Three respondents are selected to represent each dialect. The data are collected through personal interview and analyzed descriptively to find out how these aspects are realized in each dialect to ascertain their level of similarities and differences. In the findings, there are variations both in the affixes and in the tone patterns indicating that they are different (though related) dialects of the Igbo language, contrary to popular notion that they all speak the same dialect. Keywords: dialect, verb forms, tone, aspect, Igbo language I. INTRODUCTION Aguata is a geographical area that was mapped out as an administrative area in the pre-independent Nigeria and became a local government area during the Obasanjo regime of the 1970s. It is bounded on the north and west by the old Njikoka Local Government Area of Anambra State and on the east by Okigwe Local Government Area of Imo State. There are about forty nine autonomous communities that make up this region. They include but not limited to Ụmụuchu, Achina, Mkpologwu, Akpo, Enugwu-Ụmụọnyịa, Agbụdụ, Amesi, Ụmụọmakụ, Ụmụalaọma, Ekwuluọbịa, Oko, Isuọfịa, Igboukwu, Agụlụezechukwu, Nanka, Ụga, Ezinifite, Ụmụọna, Ikenga, One, Awgbụ, Ufuma, Ajali and so on.

  • Water Budget Analysis of Agulu Lake in Anambra State, Nigeria
    JASEM ISSN 1119-8362 Full-text Available Online at J. Appl. Sci. Environ. Mgt. September, 2006 Vol. 10 (3) 27 - 30 All rights reserved www.bioline.org.br/ja Water Budget Analysis of Agulu Lake in Anambra State, Nigeria 1EGBOKA, BCE; 2NFOR, BN; 3BANLANJO, EW 1,3Department of Geological Sciences, Nnamdi Azikiwe University, Nigeria 2Dept of Geology, Delta State University, Abraka, Nigeria ABSTRACT: The elements of water budget equation were analyzed for the Agulu lake area and underlying aquifers. The water budget implications for soil and gully erosion were evaluated in relation to the geological formations and hydrogeotechnics. Results show that rainfall constitutes the main source of precipitation. It ranges from 1714.04mm to 1995.53mm annually. The potential groundwater aquifer volume is 1.5 X 107m3. Discharge from aquifers contributes 7.4 X 107m3 water annually. The amount of 1.72 X 105m3 that is 60% of precipitation is lost to evaporation; 17 to 21% to infiltration. The quasi steady state of the lake water level and volume shows surface and groundwater continuity as explained by the small difference between total input and output values of the computed water budget of the lake and the aquifer. Flood studies indicate that 19.5% of the annual precipitation constitutes runoff, the main agent of gully and soil erosion, flooding and landslides. The other factors that control the distribution and location of gullies are lithologic and stratigraphical, while topography/geomorphology controls gully distribution within various geologic units. A typical gully is about 500m X 50m X 30m long, wide and deep respectively.

  • Analysis of the Diffusion of Information and Communication Technologies Among Rural Nigerian Women
    American International Journal of Social Science Vol. 2 No. 1; January 2013 Analysis of the Diffusion of Information and Communication Technologies among Rural Nigerian Women Angela N. Nwammuo, PhD Department of Mass Commutation Anambra State University Uli, Anambra State, Nigeria. Ezekiel S. Asemah Department of Mass Communication Kogi State University Anyigba, Kogi State, Nigeria. Leo O.N. Edegoh Department of Mass Communication Anambra State University Uli, Anambra State, Nigeria. Abstract Regional initiative such as Africa Information Society Initiative (AISI) and some other related societies have all tried to encourage the building of Africa’s information and communication infrastructure so as to speed up socio- economic development across the continent of Africa. Many governmental and non-governmental bodies have also supported similar initiatives. This has led to a great improvement from what it used to be in the early 1990s and what it is today. But the question remains, who benefits from all these programmes – the urban – literate Africa woman or the rural-illiterate and poverty stricken African woman? Effectively used, ICTs can enhance development through the use of the Internet, to enable rapid marketing of products, to facilitate discussion among experts on critical development issues, to share strategies for poverty alleviation; to carryout research on the management and treatment of deadly disease and to provide other relevant information to the public; among many other things. The extent to which ICTs provide individuals and groups with the ability to interact and access ideas from each other depends on the availability and diffusion of ICTs among the group concerned. This is the bedrock of this study.

  • 167 History, Land and Conflict in Nigeria: the Aguleri- Umuleri
    History, Land and Conflict in Nigeria: The Aguleri- Umuleri Experience, 1933-1999. Nwachukwu J. Obiakor http://dx.doi.org//10.4314/ujah.v17i 2.10 Abstract This paper studies the place of history, and land in the outbreak of conflicts in Nigeria, with focus on the Aguleri- Umuleri communities’ experience. Both communities were engulfed in intractable conflicts over the ownership of Otuocha land. Aside the contest over land, both communities have been engaged in the reconstruction of their history with each claiming to be the direct descendant of Eri, who both refer to as their progenitor. Studies exist on the Aguleri- Umuleri conflicts, but these works focused only on the contest over Otuocha land as the sole cause of the conflict, neglecting the aspect on the perceived distortion of history, which appear to be the underlying factor. This paper addresses this imbalance. The paper adopts the multi-disciplinary approach, as well as the thematic method of presentation. The paper basically draws from primary and secondary sources. Primary sources are derived from oral interviews, while the secondary sources are mainly obtained from books and journal articles. The conflict led to loss of lives and property, destruction of the economic base of the belligerent communities, high crime wave, and historical revisionism of the area. Though the conflict may seem to have ceased, the issues at stake remain unresolved. This paper among other things recommends a revision of the Eri mythology to establish the true nature of the relationship between the two communities. 167 UJAH: Unizik Journal of Arts and Humanities Introduction The history of Nigeria is replete with cases of conflicts.

    1.1 CHAPTER 1 INTRODUCTION Soil erosion is the systematic removal of soil, including plant nutrients, from the land surface by various agents of denudation (Ofomata, 1985). Water being the dominant agent of denudation initiates erosion by rain splash impact, drag and tractive force acting on individual particles of the surface soil. These are consequently transported seizing slope advantage for deposition elsewhere. Soil erosion is generally created by initial incision into the subsurface by concentrated runoff water along lines or zones of weakness such as tension and desiccation fractures. As these deepen, the sides give in or slide with the erosion of the side walls forming gullies. During the Stone Age, soil erosion was counted as a blessing because it unearths valuable treasures which lie hidden below the earth strata like gold, diamond and archaeological remains. Today, soil erosion has become an endemic global problem, In the South eastern Nigeria, mostly in Anambra State, it is an age long one that has attained a catastrophic dimension. This environmental hazard, because of the striking imprints on the landscape, has sparked off serious attention of researchers and government organisations for sometime now. Grove(1951); Carter(1958); Floyd(1965); Ofomata (1964,1965,1967,1973,and 1981); all made significant and refreshing contributions on the processes and measures to combat soil erosion. Gully Erosion is however the prominent feature in the landscape of Anambra State. The topography of the area as well as the nature of the soil contributes to speedy formation and spreading of gullies in the area (Ofomata, 2000);. 1.2 Erosion Types There are various types of erosion which occur these include Soil Erosion Rill Erosion Gully Erosion Sheet Erosion 1.2.1 Soil Erosion: This has been occurring for some 450 million years, since the first land plants formed the first soil.

Eduputa4 1Department of Geography and Meteorology, Nnamdi Azikiwe University, Awka, Nigeria. 2Department of Geography, University of Nigeria, Nsukka, Nigeria. 3Civil Engineering Department, Federal Polytechnic, Oko, Nigeria. 4Department of Environmental Management, Nnamdi Azikiwe University, Awka, Nigeria. Accepted 22 July, 2013 The aim of this paper is to determine relevant factors contributing to the water demand in the peri-urban communities of Awka capital city. Towards achieving this aim, questionnaire were developed and served on the households in various communities to collect relevant data on the 13 physical and socio- economic factors we earlier identified as influencing water demand in the area. Water quality was ascertained through microbiological analysis of water samples. The major analytical techniques used were multiple correlations, the result of which was subjected to Principal Component Analysis (PCA) and Principal Component Regression. Result shows that the 13 variables combined to contribute 90.0% of water demand in the area. Furthermore, the low standard error of estimates of 0.029 litres shows that water demand in the communities could be predicted using the 13 variables. Policy and planning measures to improve the water supply situation of the area were suggested. Key words: Capital, communities, factors, peri-urban, water demand.
