Impact of Climate Change on Soil Properties of Farms in Southern Guinea Savanna Using Machine Learning and Remote Sensing Approach.
(Nigerian Journal of Soil and Environmental Research., 2026-02-02) Alabi, K.O.; Arebishola, Y.I; Afe, A.I; Saka, H.A.
This study quantitatively assessed the impact of climate change on soil properties in Asomu Farm and Malete Teaching and Research Farm using remote sensing and machine learning approaches. Landsat 8 satellite imagery from 2018, 2020, and 2024 was processed to derive the Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), and Soil Moisture Index (SMI). The NDVI increased from 0.23 in 2018 to 0.42 in 2024, indicating improved vegetation density and health. Correspondingly, LST decreased from 35.6°C in 2018 to 32.1°C in 2024, suggesting a reduction in surface heat stress over time. SMI values revealed a consistent improvement in soil moisture levels, rising from 0.31 in 2018 to 0.47 in 2024. These changes suggest that the soil in both locations has become more resilient to moisture loss, likely due to increased vegetation cover and possibly improved rainfall patterns. Machine learning algorithms were applied to identify patterns and correlations between NDVI, LST, and SMI, enhancing the prediction of soil condition trends under varying climatic scenarios. The study concludes that integrating remote sensing with machine learning offers a reliable, data-driven approach to monitor the effects of climate change on soil systems. The quantitative results provide a strong basis for recommending climate-smart agriculture and adaptive land management practices in semi-arid regions of Nigeria.

PERFORMANCE AND BLOOD PROFILE OF BROILER CHICKENS FED DIETS CONTAINING GRADED LEVELS OF Moringa oleifera SEED MEAL
(Faculty of Agriculture, University of Maiduguri, 2026-01-27) J.O. Aremu, A.A. Annongu, D.F. Apata, A.O. Abdulraheem, O.M. Adesina, AL. Ambali, H. Ishola, F.O. Ogunsola, R.O. Imam, K.Y. Oganija
ABSTSRACT: A 56-day feeding trial was undertaken to investigate the effects of graded levels of ethanol treated Moringa oleifera seed meal (ETMOSM) on performance, serum and haematological characteristics of broiler chickens. 150-day-old Arbor acre chickens used in this experiment were subjected to five dietary treatments as follows; Diet 1-the control devoid of Moringa oleifera seed meal (0%MOSM), diets 2, 3, 4, and 5 –ETMOSM at graded inclusion levels of 2.5, 5.0, 7.5 and 10.0% level respectively. Results showed that ETMOSM had an effect (p<0.05) on the growth performance and blood profiles. There was better performance up to 2.5% MOSM but the performance declined significantly at a higher inclusion level. There was an improvement in the haematological ((PCV, RBC, HB) parameters up to 10% MOSM inclusion. The AST ALP, total protein and albumin increased significantly with the increased level of MOSM while Alkaline phosphatase reduced with the increased level of MOSM: nevertheless, there were no influence (P > 0.05) on the urea values. It can be suggested from the findings of this research that ethanol treated MOSM can replace soya bean meal in broiler chick diets up to 10% without deleterious effect on the growth and blood profile

Food & Beverages Revolution: Trends and Innovation.
(Success Printing Enterprises., 2024) Folorunso, Olusola Samsom; Osadare Oluwakemi Olawunmi
The global food and beverage sector is undergoing a profound transformation driven by shifting consumer preferences, technological innovation, sustainability imperatives, and evolving cultural identities. This book explores the contemporary food and beverage revolution, examining how emerging trends are redefining production systems, consumption patterns, value chains, and regulatory frameworks across both developed and developing economies. Drawing on interdisciplinary perspectives from food science, hospitality management, agribusiness, nutrition, cultural studies, and sustainability, the book critically analyzes key trends such as plant-based innovations, functional foods, alternative proteins, digital food platforms, ethical sourcing, circular economy practices, and the revalorization of indigenous cuisines and beverages. The book further interrogates how globalization, climate change, urbanization, and health consciousness are reshaping food and beverage choices, while also highlighting the tensions between tradition and innovation. Particular attention is given to the role of entrepreneurship, technology, and policy in driving inclusive growth and resilience within the sector. By situating global trends within local and regional contexts, especially in emerging markets, the book provides nuanced insights into how food and beverage systems can respond to contemporary challenges while preserving cultural authenticity. Ultimately, this book positions the food and beverage industry as a critical arena for economic transformation, social innovation, and sustainable development. It serves as a valuable resource for scholars, policymakers, industry practitioners, and students seeking to understand the forces shaping the future of food and beverages in an era of rapid change.

Municipal Solid Waste Generation, Recovery and Recycling
(Research | Reviews | Publications, 2012-10) Mohammed B OUMAROU; Mohammed DAUDA; Abdulbaqi T ABDULRAHIM; Alhaji B ABUBAKAR
The paper presents a case study focused on waste generation, material recovery, and the recycling potential of municipal solid waste in Maiduguri, Nigeria. The municipal solid waste (MSW) generation was estimated using a fuzzy logic based mathematical model followed by a collection scenario thought of, adopted and tested within two planned residential areas; the University of Maiduguri campus and the 202, 303 housing estates of the Maiduguri metropolis. Data obtained were analyzed using simple statistical methods. The mathematical model predicted 255 tonnes of MSW against 226.63 tonnes by collection estimates. An important amount of recyclable materials was found to be generated within the study area. Incurred fuels expenses on the trucks alone, do exceed the monthly wages of 400 waste collectors. MSW collection, material recovery and recycling are alternatives to fight poverty, and contribute immensely towards social re-insertion of marginalized people. Further research is needed on the waste production equation for estimates of waste generation in not well planned areas.

Design analysis of solar bi-focal collectors
(2012-02-02) Abdulrahim A; Diso I. S; Abdulraheem A. S
This study carried out the design analysis of solar bi-focal collectors with the basic units comprising the paraboloid concentrators, receivers and support/connectors. The design of the receivers is such that it works on thermo-siphon principle while the heat energy requirement for each receiver is 650 kJ. Solar energy required to provide the needed power input in the collector’s receiver is amounted to 0.967 kJ/s. The results of the analysis revealed that each collector has diameter of the receiver of 0.3 m, aperture diameter of 1.4 m and internal surface area of 1.53 m2. The materials and dimensions of parts were selected based on the design specifications. The design analysis will serves as basis for the development of a solar tracking bi-focal collector system for possible steam generation.
