Urban Waste Management Challenges in Developing Nations: A case study of Ilorin, Nigeria
(African Journal oof Earth and Environmental Sciences, 2025) Mohammed Sani,Alaya Z.T ,A .TAliu.
This work is to assess the waste Management challenges confronting the developing nation taking Ilorin in Nigeria as a case study. The aim is to examine the effect of solid waste disposal in Ilorin Metropolis, Kwara State. The objective is to look into different physical constituents and characterization of solid waste, analyze the spatial relationship between the dumpsite and population. Proffer best method of waste management in Ilorin Metropolis. Generation of waste the world over is synonymous with increase in population due to changes in taste and life style of the people. This work used field survey, secondary data from Kwara State Waste Management Agency and ArcGIS look at different Constituents and Physical Characteristics of Solid Waste in the Dump Site within Ilorin Metropolis. pH levels were found to be highest in areas with high organic waste content, suggesting that the decomposition of organic waste is contributing to the alkalinity of the solid waste site within Ilorin metropolis and is likely have health effect. The moisture content of the solid waste disposal site ranged from 40% to 50% with an average value 45.7%. This indicates that the site has moderate moisture levels, which is consistent with the presence of organic waste. The moisture content was found to be highest in areas with high food waste content, suggesting that food waste is contributing to the moisture levels of the sites. Temperature of the solid waste site ranged from 220c to 250c with an average value of 22.70c. This indicate that the site has high temperatures, which is consistent with the decomposition of organic waste. The temperature was found to be highest in areas with high decomposition rates, suggesting that the decomposition of organic waste is contributing to the generation of heat at dump site. In effect this can contribute to global warming and result to climate change. The proximity of waste disposal sites to populated areas can lead to environmental and health risks. Developing good waste management practice, good attitude towards waste management will help to minimize its impact from our various homes. Teaching of Waste Management should be included in the school curriculum from Primary, Secondary and higher institutions.

EFFECTS OF ANTHROPOGENIC ACTIVITIES ON VEGETATION CHANGES 67-75 IN GUINEA SAVANNA REGION OF NIGERIA- A CASE OF EDU LOCAL GOVERNMENT, KWARA STATE
(Department of Geography and Environmental Mnagement University of Ilorin, 2024) mohammed Sani and IYANDA Y.A.
This work examined effects of anthropogenic activities on vegetation changes in Guinea savanna region of Edu Local Government Kwara State, Nigeria. There are various economic activities going on in the region and these activities have significantly contributed to the changes in the vegetation cover of the study area. Erdas Imagine 2015 was for computerizing NDVI, ArcMap version10.5 for images extraction; mapping of study area and NDVI mapping; ArcMap 10.5 for the conversion of the images (vector) to raster and excel for the calculation percentages and graphs. Normalized Difference Vegetation Index (NDVI) were used as method for detecting any form of changes in Edu local government open forest. NDVI result shows (-0.26) which indicates a decrease in vegetation cover in the study area. The vegetation index Map of 1990, 2005-2018 also shows that there is further decrease in vegetation (0.58) (0.48) in 1990 and 2005 respectively. NDVI values of (0.35) indicated a decline in the vegetation of 2005 -2018(0.48) (0.35) respectively. The patches of thick green colour of 1990, 2005 and 2018 images show continual decreased of forest from 1990-2018.The shrubs continue to expand from 1990-2018.This means that, there is sharp decline in the Forests cover between the intervals of another fifteen years. Tree planting campaign should be undertaken through print and electronic media, public and private owned radio stations. The campaign should educate recent flood events that ravaged the region.

LEAD ASSESSMENT IN DOMESTIC WATER SOURCES IN KWARA STATE, NIGERIA
(African Journal of Geographical Sciences (AJGS), 2025-05-21) 1Mohammed S
The rate of Water contamination by lead in sub–Saharan Africa is at an alarming rate, and it is a source of concern for the Environmental managers especially in Nigeria. Physiochemical parameters in water samples from tap water, well water, and river water in Malete were assessed. Water samples were collected over two weeks, and parameters such as turbidity, Total Dissolved Solids (TDS), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), pH, and lead (Pb) concentrations were measured using standard procedures. The results were then compared with World Health Organization (WHO) standards for drinking water. The major findings revealed that the Zinc and lead concentrations in Malete's water sources significantly exceeded WHO's permissible limits of 0.01 mg/L, with the highest lead levels detected in the Malete River (0.085 mg/L). Other physiochemical parameters, including TDS, COD, and BOD, indicated varying degrees of water quality issues, with particularly high organic pollution levels in the river water. These findings suggest that the water contamination originated from a combination of aging infrastructure, such as decayed lead pipes, and dumping of refuse. There is urgent need to take measures to curb this from escalating, youth occupy large space in to future generation, save guarding their health is key to national development. Replacing corroded lead pipes and alternative source of water will help reduce over dependent on one source of water.

PROXIMATE STUDY, MINERAL AND ANTI-NUTRIENT COMPOSITION OF CYMBOPOGON CITRANUS LEAVES HARVESTED FROM ILORIN, NIGERIA: POTENTIAL BENEFITS IN ANIMAL NUTRITION AND HEALTH
(Wayamba University, Sri Lanka, 2017) Ojo Olayinka A
The leaves of Cymbopogon citranus (Lemon grass) were harvested from Kwara State metropolis in Nigeria during the late rainy season in June 2015 for the proximate, mineral and phytochemical analysis .This study was conducted to know the nutritive value of lemongrass harvested and its potential in Animal Production and health. The standard procedures of AOAC (2003) were used to analyze the proximate composition and mineral analysis. The results of proximate analysis revealed the presence of high crude protein (8.51% ±0.06). The leaves also contained appreciable amounts of crude fibre (4.49% ±0.02), ash (8.02% ± 0.04), crude fat (2.99% ±0.02). The total ash content showed it contained minerals, Ca (0.62% ±0.00), K (1.59% ±0.01), Na (280.00±0.01), Fe (286.5±0.01), Mn (61.56±0.15), Zn (21.91±0.06) and P (30.15±0.00) parts per million (ppm). Magnesium (0.44% ±0.00) and copper (5.73±0.00) were the least. The results of phytochemical analysis and antinutrients showed presence of tannins (0.006% ±0.00), saponins (0.67% ±0.00), alkaloid (0.53%±0.00), steroids (0.001±0.00), phenols (0.07±0.00) and flavonoids (0.001±0.00). The presence of these essential nutrients and minerals showed that Lemon grass is a potential source of feed supplement to enhance maximum productivity and improve growth performance of livestock.
