Question

Read the passage below carefully:

Cassava has long served as a vital staple crop for millions of households across West Africa, providing essential dietary carbohydrates and serving as a reliable buffer against food insecurity. In recent years, small-scale farmers in rural Nigeria have increasingly adopted modern solar-powered processing equipment to convert raw cassava roots into high-grade cassava flour and garri. Traditional processing methods relied heavily on firewood, which contributed significantly to local deforestation and exposed processors to harmful smoke emissions. The introduction of solar dryers and mechanized graters has drastically reduced processing time from five days to less than forty-eight hours, while simultaneously enhancing the hygienic quality of the final products. Consequently, local farmers have seen a substantial increase in their profit margins, as their refined produce now satisfies the stringent quality standards required by commercial bakeries and urban supermarkets. Although initial capital costs for solar technology remain high, cooperative micro-financing initiatives are helping community groups overcome these financial barriers. Overall, the transition to solar-powered cassava processing has transformed rural livelihoods by boosting agricultural efficiency and promoting environmental sustainability.
