Read the passage below carefully:
For centuries, smallholder farmers across the dry savannas of West Africa have cultivated fonio, an ancient cereal renowned for its extreme drought tolerance and rich nutrient profile. Despite its ecological resilience and health benefits, traditional fonio processing was exceptionally labor-intensive, requiring women to spend hours manually pounding the tiny grains with wooden mortars to remove the tough outer husk. This grueling post-harvest bottleneck severely restricted commercial production and kept farm yields locked in subsistence-level trading. In response to this challenge, regional engineers developed mechanical fonio dehullers capable of processing hundreds of kilograms per hour. By eliminating manual husking, these machines drastically reduced processing time, lowered labor costs, and enabled farmer cooperatives to scale up commercial packaging for urban markets. While some local communities initially lacked access to electricity to run earlier diesel-powered prototypes, recent solar-powered models have expanded processing capabilities to off-grid villages, transforming fonio from a neglected traditional crop into a lucrative staple across regional markets.
