This study was conducted to assess the major livestock feed resources and feeding systems in the Dalifage district of the Afar Regional State, Ethiopia. Three representative kebeles from pastoral and three from agro-pastoral areas were purposively selected, from which 151 households were randomly chosen for semi-structured individual interviews. The major feed resources identified included fodder trees and shrubs (such as...

The oils of two underused Guinean oilseed species, Panda oleosa and Treculia africana, are compared for the first time in this study. Dichloromethane-based Soxhlet extraction produced 20.1% for T. africana and 28.6% for P. oleosa. Chromatographic examination showed that triacylglycerols dominated comparable patterns. Nuclear magnetic resonance (NMR) spectroscopy (¹H, ¹³C and Distortionless Enhancement by Polarization Transfer...

Climate change and rapid urban growth are increasingly altering local climatic conditions in cities across the Global South. One important manifestation is the urban heat island (UHI) effect, whereby built-up urban areas experience higher temperatures than surrounding less-developed areas. This study examines the relationship between climate change, urban growth, and rising temperatures in Ikorodu, a rapidly expanding...

This paper explores three key international transmission channels of the United States (US) monetary policy from African perspective using the Bayesian VAR (BVAR) framework with monthly data over the period 2006 to 2024 and sheds light on the relative strength of the transmission channels. After examining the integrational properties of the data and estimating the models, the impulse response functions and forecast error...

Chronic hepatitis delta virus (HDV) infection exacerbates hepatitis B virus (HBV)-related liver disease. In Côte d’Ivoire, HDV is systematic not systematically screened among hepatitis B surface antigen (HBsAg)-positive blood donors, and most regional estimates rely on anti-HDV serology, which indicates exposure but not active replication. This study aimed to determine HDV RNA replication positivity among HBsAg-positive blood...

Quantifying hydrological contributions from tributaries to lagoon systems represents a major challenge for understanding the functioning of coastal hydrosystems and for the sustainable management of water resources, particularly in tropical environments exposed to strong climatic and anthropogenic pressures. This study aims to assess flood contributions from the Bété River to Lagune Aghien, a strategic potential resource for...
