Item Development of Draught Early Warning System (DEWS) in Nigeria: A Review of Progress, Challenges and Future Directions(ICEC, 2025) AJiboye, Johnson Adegbenga; Ofeoshi, C. I.; Adesiji, A. R.; Saidu, M.Drought Early Warning Systems (DEWS) are important tools for reducing the impact of drought on agriculture, water resources, and food security. This review explores drought trends in Nigeria, assessing the progress, challenges, and future directions of DEWS development. Analysis of past drought occurrences reveals that Nigeria has experienced notable drought episodes in 1914, 1924, 1935, 1943, 1951-1954, 1972-1973, and 1991-1995, with the driest decades recorded between 1970 and 1990. The increasing trend of drought events is linked to climate change, land degradation, and poor water management. Nigeria's primary DEWS, managed by the Nigerian Meteorological Agency (NiMet), employs indices such as the Standardized Precipitation Index (SPI) and the Palmer Drought Severity Index. However, these systems face significant challenges, including data gaps, limited technological integration, and inadequate community participation. An analysis of past studies shows advancements in satellite-based vegetation health indices, climate modelling, and machine learning algorithms. However, DEWS effectiveness is hindered by institutional weaknesses, data limitations, and insufficient stakeholder engagement. Key challenges include governance, coordination, funding, and capacity building. Future research should focus on intègrating local knowledge and indigenous practices, developing more complex and integrated DEWS models, improving data quality, and enhancing communication strategies. This review aims to inform policymakers, researchers, and practitioners about the need to strengthen DEWS to support drought resilience and sustainable development in Nigeria.Item FROMHIDDENTOHIGHLIGHTED:TRANSFORMINGSCHOLARLYVISIBILITYTHROUGHMETADATAPRACTICESINNIGERIA(DEPARTMENT OF LIBRARY AND INFORMATION SCIENCE, FEDERAL UNIVERISTY LOKOJA, 2024-12-11) ODIGIE,Ojeime Imoisili; BABALOLA, G. A.; UDENSI,Nkechi Juliana; SALAU,AdetoroSadiatThis study explores the relationship between metadata practices and scholarly visibility within Nigerian institutional repositories between 2020 and 2024. Recognizing metadata as the backbone of digital resource discoverability, the research investigates how metadata quality influences citation metrics and overall accessibility of scholarly outputs. Employing a quantitative methodology, data was sourced from the Directory of Open Access Repositories (OpenDOAR) to evaluate 27 functional repositories across Nigeria. Key descriptive metadata elements, including titles, authors, abstracts, and keywords, were assessed for completeness and adherence to international standards. The findings reveal significant gaps in metadata practices, with repositories displaying varying levels of completeness and citation impact. Notably, repositories with comprehensive metadata fields exhibited higher citation levels, highlighting the importance of metadata in enhancing scholarly visibility. urgent need for skilled personnel, adherence to global metadata standards, and institutional support to optimize Nigeria's repository infrastructure. A strategic framework is proposed to address these gaps, focusing on repository functionality, metadata completeness, and user engagement, to improve the discoverability and impact of Nigerian academic outputs.Item DISTRIBUTION AND ABUNDANCE OF MOSQUITOES IN RELATION TO MALARIA PREVALENCE IN CHANCHAGA LOCAL GOVERNMENT AREA OF NIGER STATE, NIGERIA(International Journal of Applied Biological Research, 16 (1), (Impress), 2025) Abdullahi, M.; Ismail, A.; Abolarinwa, S. O.; Ocha, I. M.; Amos, A.V.; Omalu, I. C. J.In spite of intensive control measures and intervention in Nigeria, malaria remains a major public health threat. The dearth of information on the diversity and distribution of Anopheline mosquito species, a prerequisite to successful malaria control, informed this study. Indoor adult mosquito populations were sampled using Pyrethrum Spray Catches (PSC). Two hundred and seventy-six (276) human individuals were examined for malaria parasites using Giemsa staining techniques. All individuals were screened for the presence of malaria parasite and classified into four (4) age groups: < 5 years, 6 – 10 years, 11 – 15 years and >16 years. A total of one thousand five hundred and sixteen (1516) mosquitoes were collected and identified as follows; Anopheles species 371 (24.47%) and Culex species 1145 (75.53%). Mosquitoes collected per location was as follows F-layout 399 (26.31%), Tunga 406 (26.28%), Chanchaga 361 (23.81%) and Sauka-Kahuta 350 (23.08%). The distribution of mosquitoes per location showed a significant difference at p<0.05. Six species of Anopheles mosquitoes were identified. These are Anopheles gambiae, 235 (63.34%), Anopheles funestus, 111 (29.92%), Anopheles coustani,10 (2.69%), Anopheles nili, 6 (1.62%), Anopheles squamosus, 6 (1.62%) and Anopheles moucheti,3 (0.81%). Tunga had the highest number of Anopheles mosquitoes of 116 (31.27%), followed by F-layout 93 (25.07%) while Sauka-Kahuta had the least number of Anopheles mosquitoes collected 74 (19.95%). Out of the 276 human blood specimens examined, 178 (64.49%) were positive for Plasmodium falciparum. Individuals of age group 6 – 10 years had highest infection rate of 40 (78.43%), followed by 16 years 87 (63.50%) while age group 0 – 5 years, had the least infection rate of 6 (56%). Males were more infected 91 (67.91%) with malaria than females 87 (61.27%) which also showed a significant difference at p<0.05. This study demonstrated the complex distribution of Anopheles mosquito and the considerable variations in the intensity of malaria transmission in Chanchaga Local Government and its environs, hence the need to intensify control strategies to eliminate larva sources of the vectors.Item Investigation of gastrointestinal parasites of solid waste from dumpsites in Bosso Local Government Area, Minna, Niger State Nigeria.(Book of Proceedings of the 1st International Conference of the School of Life Science, Federal University of Technology, Minna, 2024-08) Ismail, A.; Ogbe M. E.; Omalu, I. C. J.; Abolarinwa, S.O.; Abdullahi, M.; Faisal, A.The study was carried out to investigate the prevalence of intestinal parasites in dump site in Minna metropolis. This was achieved via series of coordinated research across five (5) different dump sites designated as A, B, c, D and E. The five dump sites were spread within three locations (Mypa, Boss Market and Bosso New York) of Minna metropolis. Soil and household waste were collected at different interval following stand procedures and processed using zinc floatation method. The result from the 25 soil samples showed that almost all the dump sites had at least one gastrointestinal parasites. The seven (7) species of gastrointestinal parasites isolated includes: Ascaris lumbricoides 23 (22.77%), Taenia spp 11(10.(p89%), Entamoeba histolytica 25 (24.75%), Entamoeba coli, 14 (13.86%), Giardia lamblia 11(10.89%), hook work, 8(7.92%) and Strongyloides stercoralis, 9 (8.91%). The highest number of parasites were isolated from dump site D, 24 (23.76%) while the least parasites abundance was recorded in dump site C, 14 (13.86%). Overall prevalence of gastrointestinal parasites in the dump sites (Market and household waste) revealed that 101 (59.76%) and 68(40.24%) of the total isolated parasites were found in markets and household waste respectively. The parasites that were most prevalent in the dump site was A. lumbricoides 38 (22.49%) while Strongyloides stercoralis 16 (9.47%) was the least abundant. Statistically, there was no significant difference (p>0.05) in the abundance of parasites in relation tho market and household dumsite investigated. This study revealed a significant abundance gastrointestinal parasites in the dump sites.Item Empowering Youth Through Technical and Vocational Education and Training for Economic Inclusion and National Security(SCOA Heritage Nigeria Ltd, 2024) Ibeneme, O. T.; Igwe, C. O.Item Understanding Sustainability in Building Construction(Proceedings of the Builder's Conference and Annual General Meeting, 2021) Bustani, A. B.; Igwe, C. O.; Usman, N. D.; Adamu, S.Construction industry makes a significant contribution to the growth and development of every economy by providing infrastructure for productive ventures, shelter to the citizens and generating employment to people at different levels of knowledge and skills. It is the backbone of economic development globally. The construction industry can be vibrant when technologies, systems, materials and the processes are of quality standards. Issues of energy consumption, wastage, water and air pollution threatens the health and safety of the people as well as the built environment. The sustainability will not be feasible when the Construction industry have performed below expectations evident by high rate of building collapses, non-compliance of health and safety, loss of lives and properties as well as lack of standards and quality infrastructure for economic development. This has greatly affected the living standards of an average Nigerian. Therefore, understanding sustainable building construction is hinge to pivot development in the construction sector. The method used for the research is exploratory based on relevant literature survey for better understanding of the sustainable building construction. The study concludes that maximizing the use of efficient building material and construction practices, optimizes the use of onsite resources and use of renewable sources of energy, use efficient waste management practices and provide comfortable and hygienic indoor working conditions.Item Improving Instructional Delivery in Technical Vocational Education and Training for Skills Development in the Era of COVID-19 Pandemic in Nigeria(Conference: Proceedings of the 34th Annual National Conference of Technology Education Practioners Association of Nigeria,, 2021) Eze, C.

O.; Yayock, D. S.; Yayock, D. S.; Ibrahim, D.; Ayorinde, G. O.This study examined low income and its effect on the standard and quality of residential building in Kaduna State, Nigeria. Two research questions were developed and answered while two null hypotheses were formulated and tested at 0.05 level of significance and 100 degrees of freedom. Descriptive survey research design was adopted for the study. The entire population of 2,019 respondents consisting of 1,435 registered residential buildings and 584 builders in Kaduna State were used for the study. A 24 item structured questionnaire developed from the literature reviewed for the study was used to collect data from the respondents. Each questionnaire was divided into two categories of; reasons for acquiring low quality materials and curtailing the difference between low income and the standard and quality of residential buildings in Kaduna State. The "reasons for acquiring low income materials" had a four (4) response options of Highly Often (HO), Often (O), Moderately Often (MO) and Not Often (NO). The "curtailing the difference between low income and the standard and quality of residential buildings" category also had 4 response options of High Agree (HA), Agree (A), Moderately Agree (MA) and Not Agree (NA). The questionnaire items were face validated by three experts. The 2,019 copies of the questionnaire were administered on the respondents with the help of two research assistants. 694 copies of the questionnaire administered were retrieved and analysed. Weighted mean, standard deviation and Improvement Need Index (INI) were used to answer the research questions while t-test statistic was used to test the null hypotheses 1 and 2 respectively. The findings of the study revealed that low income has effect on the standard and quality of residential buildings in Kaduna State, Nigeria. The findings on hypotheses1 and 2 revealed that there was no significance difference in the mean ratings of the respondents (Residential Building Clients and Builders) on all the items on reasons for acquiring low quality materials and ways of curtailing the difference between low in come and it's effects on the standard and quality of residential buildings in Kaduna State, Nigeria. It was therefore recommended that theministry of urban and town planning should organised orientation/seminar from time to time to brainwash the residential building client on what is required at each stage of the housing value chain, from foundation footing to roofing and finishing, and from engaging locals from the communities, to building and improving the standard and quality of their residential buildings so that it will to be safe, resilient and sustainable. There should be a provision for an effective loan scheme, partial upgrading, effective urban development policy, and improvement of sanitary conditions and enforcement of housing and building codes.Item Level of Occupational, BrickStress and Self-Efficacy on the Productivity of Blocklaying, Bricklaying and Concreting Teachers in Technical Colleges in North Central, Nigeria(Book of Proceedings of 10th International Conference of School of Science and Technology Education, Federal University of Technology, Minna, 2024) Tsado, E. G.; Igwe, C. O.; Saba, T. M.The study investigates the Level of pressure of occupational stress and self-efficacy on Blocklaying, Bricklaying and Concreting teachers (BBC) productivity in Technical Colleges in North Central, Nigeria. The study utilized quantitative method. The population of the study was 83 BBC teachers from Technical Colleges offering BBC subjects in the 6 North Central States and the Federal Capital Territory. Census sampling was carried out to select the entire 83 BBC teachers from the Technical Colleges in North Central States including the FCT. The study used a structured questionnaire of a 4-point Scale rating as the instrument of data collection validated by 3 research experts. Frequency distribution, mean and standard deviation were employed to analyze the individual responses of the respondents while regression analysis was used to determine the relationship between level of pressure of occupational stress and level of self-efficacy on teachers’ productivity of BBC teachers in Technical Colleges. The findings of the study revealed a coefficient of -0.3.46 of occupational stress and 0.260 of self-efficacy respectively indicating an inverse relationship between occupational stress and BBC teachers’ productivity and a positive relationship between selfefficacy and BBC teachers’ productivity. In addition, the study revealed that both occupational stress and self-efficacy have significant relationship with teachers’ productivity at 5°o level of parenthesis. The study however recommends that technical colleges should focus on implementing strategies that will effectively manage and reduce stress levels among teachers and focus on building teachers’ self-efficacy belief.
