    Irrigation Water Quality and the Impact on Cash Crops In Sahel Savanah Zone of Northern Nigeria
    (2020-07-07) Ndububa, Olufunmilayo
    Water pollution is a global challenge; which can be defined as any impairment in its native characteristics by addition of anthropogenic contaminants to the extent that it either cannot serve humans for drinking purposes and/or support the biotic communities. The effect of agrochemicals on fresh water quality could render the water unsuitable for human and animal consumption, removal of agrochemical contaminants from water is possible, preventive measures to avoid pollution is however preferable. Based on these prevailing circumstances, this research was conducted to assess the physiochemical properties and grochemical residues in water samples used on irrigated lands in North Eastern, Nigeria, to determine the chemical properties of the irrigation water in some locations of Bauchi State and to analyze data using statistical tools, and comparison of results with international and national water quality standards. Result shows that Boron values in the irrigation water were higher than tolerant values for cash crops including crops such as pear, grapefruit and lemon which will not thrive in the areas under consideration due to the high boron content of the water. Plants such as beans, date palm, onions, cabbage and lettuce are some of the crops that can readily be grown in North Easter part of Nigeria.

    Investigating the Role of Library and Information Science (LIS) Professionals in Promoting Information Equity: A Review
    (Journal of Library and Information Management, Technology, Education, 2026) Umera, O.R
    This study investigated the role of Library and Information Science (LIS) professionals in promoting information equity: A Systematic Descriptive Review. The research was guided by five research questions aligned with its objectives, focusing on the conceptual foundations of information equity and its relationship to the professional values and mandate of LIS professionals, populations most affected by information inequity and the specific barriers they face in accessing and using information, the strategies and programmes through which LIS professionals promote information equity in academic, public, and special library contexts, the challenges and barriers that constrain LIS professionals in their efforts to advance information equity and the emerging approaches and policy frameworks through which LIS professionals and institutions are addressing information equity in the context of the digital transformation of information provision. A descriptive research design was adopted relying on systematic documentary review and thematic description of the existing literature. Drawing on a comprehensive review of peer-reviewed literature published between 2020 and 2025.The literature reviewed for this study was sourced from open-access databases including Google Scholar, JSTOR, Emerald Insight, ScienceDirect, PubMed Central, and others. The findings revealed that LIS professionals play multifaceted roles as community connectors, digital equity advocates, cultural brokers, collection diversifiers, outreach workers, and information literacy educators in the pursuit of information equity. The results suggest that LIS Professionals significantly promote information equity to connect communities, advocates for digital equity, cultural brokers, diversifiers of collection, outreach workers and information literacy educators. The paper concludes that with evidence-informed recommendations for strengthening the capacity of LIS professionals to advance information equity in increasingly diverse and digitally stratified societies. The paper recommends that LIS schools revise their curricula to centre information equity, social justice, and culturally responsive practice as core professional competencies.

    Assessing the Role of Librarians in Managing and Promoting Institutional Repositories
    (Federal University Wukari International Journal of Library and Information Science, 2026-07-07) Umera, O.R
    Institutional repositories (IRs) have emerged as pivotal infrastructure for the preservation, management, and global dissemination of academic scholarship. Librarians, as principal custodians of information in higher education institutions, occupy a central and strategic position in the development, administration, and promotion of these repositories. This theoretical study aims to: examine the conceptual foundations of institutional repositories within the scholarly communication ecosystem; identify and analyse key roles played by librarians in managing these repositories; assess promotional strategies employed by IR librarians; interrogate theoretical frameworks governing librarian engagement with IRs; and identify challenges confronting librarians and propose strategies to address them. The study is grounded in the Change Agent Theory (Katayoon & Abrizah, 2017), the Diffusion of Innovations Theory (Rogers, 1962), and Social Capital Theory as complementary lenses for understanding librarian agency in IR ecosystems. The study adopts a theoretical research design, relying on documentary analysis and critical review of existing literature published between 2020 and 2026. Findings reveal that while librarians are well positioned to serve as change agents for institutional repositories, they face significant challenges including inadequate training, insufficient institutional support, low faculty awareness and participation, copyright complexities, and resource constraints. The paper concludes with recommendations for strengthening the capacity of librarians to fulfil their IR management and promotion roles, with implications for library policy, professional development, and institutional governance

    Selection Of Suitable Landfill Site For Waste Disposal In Ilorin Metropolis Using Geographical Information System
    (UNIOSUN journal of engineering and Environmental sciences UJEES, 2024-03-01) Abdulwaheed Abdulrasheed Alaaya
    Rapid urbanization globally has aggravated and worsen the management of municipal solid waste (MSW) in cities, especially the developing countries. This article underscores the pressing need for effective waste management solutions from the unruly contamination of soil and groundwater, or improper waste disposal and focuses on the selection of suitable landfill sites using Geographic Information Systems (GIS) techniques. With a global increase in MSW generation, especially in Sub-Saharan Africa, the environmental and health consequences of open dumping is hazardous. The study employs Multi-Criteria Evaluation (MCE) and Analytical Hierarchy Process (AHP) within the GIS environment, considering criteria such as elevation, slope, aspect, soil properties, proximity to roads, water bodies, and settlements. The analysis integrates diverse data sources, including remote sensing and soil databases, offering a comprehensive evaluation of topographical factors, soil characteristics, and accessibility. Results indicated that approximately 29.73%, falls under the category of "Restricted Area," totaling 18,887.18 hectares. High Suitable areas cover 15.85% of the region, comprising 10,070.28 hectares, while "Very High Suitable" areas, though minimal in coverage at 0.02%, represent nearly perfect sites totaling approximately 12.35 hectares. The results offer valuable insights into landfill suitability, providing a foundation for informed decision-making and sustainable waste management strategies.
