摘要

Africa is facing a food insecurity crisis, with approximately 346 million people struggling to access nutritious food and 690 million people living in poverty and facing malnutrition. This crisis is driven by a range of factors, including harmful farming practices, excessive use of agrochemicals, flooding, hydrocarbon pollution, armed conflict, insecurity, and the impacts of climate change. Ironically, while agrochemicals are intended to enhance plant growth, their overuse often exacerbates food insecurity, highlighting the urgent need for more sustainable food production methods. To address these challenges, a shift from invasive farming practices to eco-friendly green farming is essential. Eco-friendly microbial inoculants have emerged as a transformative and sustainable solution, acting as nutrient supplements and plant growth promoters. These microbial agents support plant growth through mechanisms such as phytohormone production, nitrogen fixation, phosphate solubilization, and antibiotic production. Laboratory and field trials have consistently demonstrated their effectiveness in promoting sustainable plant growth, particularly under nutrient-deficient and environmentally stressed conditions. This review paper explores the economic and environmental challenges posed by agrochemical usage in agriculture and examines the current state of food production in Africa. It highlights microbial inoculants as a promising alternative, showcasing practical successes and commercially available products. The report also addresses the current food security situation in Africa, the adoption of microbial inoculants in food production, and the challenges, trends, and future prospects of this technology within the African context.
