The soils of Burkina Faso are poor in major nutrients, with a particularly pronounced deficiency in phosphorus. However, the country has enormous deposits of natural phosphate (Burkina phosphate), but these are little used in agricultural production because of their slow solubilization. Phosphate rock was therefore processed to make the phosphorus more readily available to crops. This processing involved partial acidification and calcination.

Dans les régions sahéliennes, les collectivités territoriales sont confrontées à des changements climatiques qui affectent les systèmes de production et les moyens d'existence des populations. Cette étude analyse les tendances et le niveau d’intégration des changements climatiques dans les Plans de Développement Communal (PDC)de Bandé. L’étude repose sur des données climatiques journalières couvrant la période 1981-2024, complétées par des enquêtes auprès des acteurs locaux et une évaluation des documents de planification communale.

Animal diversity is a key component of ecosystem stability and sustainable development. The Bundelkhand region of Central India spread across UP and MP supports a variety of mammals, birds, reptiles, amphibians, fishes and insects. The region supports a diverse assemblage of vertebrate and invertebrate fauna despite recurrent droughts, rocky terrain, and increasing anthropogenic pressures. However Rapid Habitat degradation, deforestation, mining, climate change, water scarcity and human- wildlife conflict have severely affected its faunal diversity.

Food insecurity remains a significant global problem especially in developing countries like Nigeria. This challenge increases human suffering and predisposes young, adult and aged to disease attack, impaired human growth and reduced life expectancy. Hence, this study examined the determinants of food security among farming households of South-South region of Nigeria. Secondary data of General Household Survey data, wave 4, panel 2018/2019 from the National Bureau of Statistics was used for the study. Purposive sampling was used to select Delta and Akwa Ibom states from the region.

India has a rich and lasting tradition of scientific and technological achievement spanning mathematics, astronomy, metallurgy, medicine, civil engineering, and organized higher education since ancient times. The paper examines five domains in science and technology viz.

Les sécheresses récurrentes constituent l’un des principaux facteurs de vulnérabilité des systèmes pastoraux au Burkina Faso, en particulier dans la région de la Boucle du Mouhoun. Cette étude vise à analyser l’impact des sécheresses sur les ressources pastorales en mobilisant une approche intégrée combinant l’indice standardisé des précipitations (SPI) et l’indice de santé de la végétation (VHI).

Lichen planus is a chronic inflammatory mucocutaneous disorder. Lichenoid drug eruption/Drug induced lichen planus is an uncommon adverse effect of several drugs. Lichen planus can be distinguished from Lichenoid drug eruption by clinical and microscopic features. Although lichenoid drug eruptions are known adverse effects of anti-tubercular therapy (ATT), idiopathic lichen planus associated with ATT is rarely reported. A 72-year-old male, diagnosed case of lumbar canal stenosis with L2-L3 tubercular spondylodiscitis was started on ATT.

Wounds are classified as neglected tropical diseases. Herbal medicines are widely used and play a significant role in the alternative management of infectious diseases, including chronic wounds, ulcers and injuries. The overall aim of this study is to evaluate the antioxidant activity and major compounds of the hydroethanolic extract of the leafy stems of Ageratum conizoides, following in vitro testing for cytotoxic activity. Phytochemical analysis was carried out using the standard differential reaction method.

Contexte: L'intégration de l'intelligence artificielle (IA) en Afrique constitue à la fois une opportunité de développement socio-économique et un défi structurel majeur, marqué par une fracture numérique, une dépendance technologique et une sous-représentation des perspectives africaines dans la gouvernance mondiale de l'IA.

The Birimian basement of Côte d’Ivoire is characterized by a complex tectono-metamorphic history, yet the structural evolution of the Kan granito-gneissic complex (KGC) and the Comoé metasediments (CMS) remains insufficiently documented. This study combines teleanalytic mapping with field-based structural measurements to reconstruct the tectonic evolution of these formations. Lineament analysis highlights four principal orientations (E-W, N-S, NE-SW, NW-SE), which correspond to successive ductile and brittle deformation phases.
