Read the passage below carefully and answer the question that follows.
For generations, farming communities across the West African Sahel have practiced zai, an indigenous soil restoration technique that involves digging small pits in barren, crusted land during the dry season. Farmers fill these shallow basins with organic compost, which attracts termites. As the insects dig underground channels, they break up the hard soil crust, allowing rainwater to penetrate deep into the earth when the rainy season arrives. Seeds planted within the pits benefit directly from concentrated moisture and nutrient-rich organic waste. While early agricultural modernizers initially dismissed zai pits as labor-intensive and primitive, recent environmental assessments highlight their unmatched efficacy in reversing desertification and boosting crop yields. Consequently, zai farming is now recognized not merely as a relic of regional heritage, but as a vital ecological strategy for rural food security in arid landscapes.
Which of the following statements best expresses the main idea of the passage?
- Zai farming is a proven traditional technique that successfully combats land degradation and enhances food security in dry regions.Cevap
- BTermites break up hard soil crusts by creating underground channels when organic compost is added to shallow pits.
- CModern agricultural methods have entirely replaced traditional zai pits throughout West African farming communities.
- DEarly agricultural modernizers successfully demonstrated that traditional Sahelian farming practices are unproductive.
