Abstract We are in a race against time to combat climate change and increase food production by 70% feed the ever‐growing world population, which is expected double 2050. Agricultural research plays vital role improving crops livestock through breeding programs good agricultural practices, enabling sustainable agriculture systems. While advanced molecular technologies have been widely adopted, phenotyping as an essential aspect of has seen little development most African institutions remains...

Mortality attributed to respiratory illnesses is well characterized in children <5 years. However, there paucity of data among older populations. Here, we leveraged from the COVID-19 Vaccine Effectiveness Evaluation establish factors associated with mortality patients severe illness (SRI) Kenya and Mali. We enrolled (≥ 12 years) requiring hospitalization for SRI, defined as acute onset (≤ 14 days) at least two following: cough, fever (reported/measured temperature ≥38 °C), chills, rigors,...

Agronomic biofortification (i.e., the application of fertilizer to elevate micronutrient concentrations in staple crops) is a recent strategy recommended for controlling Iodine Deficiency Disorders (IDDs). However, its success inevitably depends on stakeholders’ appreciation and acceptance it. By taking Northern Uganda as case, this study aimed capture compare perceptions seven key stakeholder groups with respect agronomic iodine biofortification. Therefore, we employed SWOT (Strength,...

Uganda hosts Africa’s largest refugee population, exceeding 1.5 million in early 2023. While commended for its progressive policies, which grant freedom of movement and work opportunities, the influx displaced people since 2015 has strained shared environmental resources, including slow-growing indigenous trees utilized construction fuel. Efforts to preserve biodiversity have promoted growth use faster-growing exotic tree species. However, local communities often favor as fuel sources,...
