<strong>Abstract</strong> This study examined the accumulation of contaminants in Ogu River sediments, primarily caused by illegal bunkering activities occurring along the watercourses and riverbanks. Additionally, the operations of local refinery operators and other significant chemical and petrochemical industries in the area significantly contribute to the contamination of aquatic ecosystems. This research focuses on understanding the extent of the contamination and associated risks. The concentration of heavy metals in river sediments was represented by the geo-accumulation index values co

Abstract:
Artisanal fisheries in the Niger Delta and Nigeria’s coastal waters support the livelihood of its inhabitants, thus management of water pollution has public health significance for the regions and beyond. Oil Spills and contaminated runoff from the hinterland always find their way to the coast via the extensive network of rivers and creeks across the delta. This is a major cause of marine pollution in the region. With this understanding there is a need to map and model the dynamics of oil pollution across the coastal waters of the Niger Delta, thereby providing evidence and data support for th

Abstract:
Pangi (Pangium edule Reinw) seed is known to be a poisonous material. However, it becomes safe for consumption after processing. This study determined the effect of village-level processing by the Obu Manuvu community of Marilog District, Davao City, Philippines on the antinutrient and nutritional composition of Pangi seeds. Processing methods involved washing with running water for about 15 s, boiling in water for 30 min, and soaking in flowing water in a nearby river overnight. Results showed that after processing, the levels of antinutrients such as cyanogenic glycosides and oxalates were r

Abstract. Most large-scale hydrologic models fall short in reproducing groundwater head dynamics and simulating transport process due to their oversimplified representation of groundwater flow. In this study, we aim to extend the applicability of the mesoscale Hydrologic Model (mHM v5.7) to subsurface hydrology by coupling it with the porous media simulator OpenGeoSys (OGS). The two models are one-way coupled through model interfaces GIS2FEM and RIV2FEM, by which the grid-based fluxes of groundwater recharge and the river–groundwater exchange generated by mHM are converted to fixed-flux bounda

Hence, this study analysed the Niger-Benue river flood risk and vulnerability of 256 communities in Kogi State.

Tidal creeks are vital geomorphological features of tidal flats, and their spatial and temporal variations contribute significantly to the preservation of ecological diversity and the spatial evolution of coastal wetlands. Traditional methods, such as manual annotation and machine learning, remain common for tidal creek extraction, but they are slow and inefficient. With increasing data volumes, accurately analyzing tidal creeks over large spatial and temporal scales has become a significant challenge.

Factors leading to population decline or extinction include habitat destruction, chemical pollution, alien species, poaching, infectious disease, and global warming.
