This research paper aims to determine the hydraulic properties of the water-bearing layer using parameters derived from the Dar-Zarrouk equation and characterize them into groundwater potential zones. The resistivity values of the weathered and slightly weathered layers which bearing water-bearing layers were added; an average was taken and used as...

The world today faces unprecedented environmental challenges, including climate change, clean water scarcity, ocean contamination, and groundwater pollution, largely due to inadequate technology for tracking environmental pollutants. This study introduces a Supervised Machine Learning (SML) framework using multi-class classification to assess poros...

Probiotic bacteria are increasingly in demand in the food and feed industries. A growing population and finite resources require efficient ways to maximize yields. Probiotic bacteria are gaining popularity in the food and feed industries due to their unique combination of benefits and values, which include consumer health interests, sustainability...

This study investigates the relationship between climate, agroclimatic indices, and maize yield in Nigeria, focusing on diverse agroecological zones. Climate change is poised to significantly impact agricultural output. Analysis of historical data reveals varying sensitivities to weather changes in Nigeria’s agroecological regions. Regional climate...

Understanding the spatial and temporal patterns of drought and their connection with major climate indices is crucial for creating early warning and drought mitigation strategies. This study analyzed hydrological drought variability and its association with global climate indices in the Sahel Region of Nigeria. Before conducting drought analysis, t...

The study combines two critical aspects of climate research in Nigeria. The first segment focuses on improving predictive performance of global circulation models (GCMs) employing ensemble techniques. ANN ensemble displayed significant improvement in the accuracy of climate projections, particularly in high-altitude geographic areas where tradition...

Empirical observations and theory both discourage the production and use of chemical fertilizers as they can lead to environmental pollution, soil degradation and reduction in soil fertility in the long term. In certain cases, excess nutrients from chemical fertilizers such as nitrogen and phosphorus can leach into nearby water causing eutrophicati...

The objective of this investigation was to determine whether Canna indica and Oryza sativa L. plants have the phytoremediation potential for removing heavy metals and nutrients from greywater treated in batch-fed Horizontal sub-surface Flow Constructed Wetlands (HssFCW). The HssFCW had a Hydraulic Retention Time (HRT) and organic loading rate (OLR)...

Wastewater treatment necessitates the use of an appropriate method to achieve satisfactory results. The conventional method of Alum addition has been widely used for years, but it is prohibitively expensive. This study uses Moringa oleifera, an inexpensive and readily available plant, as a natural coagulant to treat wastewater collected from univer...

Data from historical observatories and future simulations were analyzed using the representative concentration pathway (RCP) 8.5 scenario, which covered the period from 1951 to 2100. In order to characterize the drought, three widely used drought indicators were used: the standardized precipitation index (SPI), the reconnaissance drought index (RDI...

Within the hard rock terrains, stream channels are suspected to be controlled by fractures and joints. In the same light, the topographic lineaments and the lineaments observed from the aeromagnetic anomalies are expected to reflect the structural trends within the complex. This study has therefore adopted multi-data sets results first on a regiona...

The rapid growth in urban populations in developing nations such as Nigeria in recent decades and the subsequ ent accelerated urbanization trend have highlighted the need to establish environmentally suitability models. The study area falls within One of the primary methods of urban solid wastes management is sanitary landfill. Improved sitting dec...

The heterogeneous and undifferentiated nature of rocks within the Basement Complex posed a serious challenge to any hydrogeological studies. Coupled with this is the discontinuity of the aquifers nature which is considered to be naturally localized. This study takes into consideration the relationship between flow direction and flownet construction...

Drought indices are very essential in monitoring and planning for drought occurrences. Though many indices have been established over the years, it is expected that proper investigation should be done using these indices to know the ones that can better characterize the drought condition of a region or country. The current study evaluated the perfo...

An anaerobic digester was used to generate biogas using poultry droppings and banana (Musa paradisiacal) peels. The digester was tested twice with a retention period of 35 days. The first test (control) was carried out with poultry droppings and water as the feedstock using a ratio of 1:2 kg. The second test was carried out using poultry droppings,...

This experiment investigated the mechanical properties of mild steel, galvanized iron and stainless steel when subjected to tensile and flexural loading. Work pieces of 54 samples were prepared having a gage length of 30 mm for material thicknesses of 1, 1.5 and 2 mm which was replicated three times. Properties such as peak force at break, elong...

Agricultural water in the right quantity and desired quality is needed to drive agrarian revolution in Nigeria. Groundwater, among the forms of water in nature is strategic for Nigeria has it is easy to exploit, readily available not affected by seasonality and the largest natural storage of available freshwater on the planet. The study was aimed...

Climate change is a global phenomenon with multifarious unique regional consequences. Contemporary studies have established Climate change as a product of anthropogenic activities. Studies have linked extreme weather events, heat waves, increase pollution, crop failure as some of the many discernable effects of climate change. Hence, the spatial te...

Africa population growth rate is the highest among the regions of the world, especially in the urban areas. This also brings about increase in waste generation, notably is also the corresponding increase in waste disposal sites. Hence, the urgent need to develop means of safe waste disposal. Engineered sanitary landfill are designed to be environme...

Hazards from drought events has made it of utmost importance for scientist to concentrate on the establishment of a dependable early warning systems that will enable stakeholders to effectively cope with the probable effect of this climatic phenomenon. Drought assessment in the northern region of Nigeria (NRN) was conducted majorly using a self-cal...

Water is considered an inevitable resource on which human life depends. Groundwater plays important roles in sustaining and supporting human continuous existence. This study examined hydrogeological implications of flownet construction and analysis on groundwater exploration. It is to ensure the delineation of appropriate locations that can be cons...

The study analysed the effects of ethnic diversity on access to drinking water and electricity in Nigeria. Our analysis indicates that ethnic diversity at the sub-national level has reduced households' access to safe drinking water, but increased provision of electricity. The implication of the finding is that provision of targeted public goods are...

The Moringa Oleifera leaves contains a very high level of nutrients. Drying will preserve these leaves and present it more portable form. Certain qualities might be lost during drying and it is therefore imperative to determine the most appropriate drying method that will minimize the loss of nutrient to the barest minimum. The main objectives of t...
