Concept:Soil Farmer Heroes are farmers recognised by the UN FAO for restoring soil health and practising sustainable farming.
Explanation:Valluvan, a 58-year-old farmer from Pollachi district in Tamil Nadu, is the correct choice.
He was honoured as a UN FAO Soil Farmer Hero for his successful shift to multi-crop, tree-based farming.
In 2009, he changed his farming method after losing about
Rs 200 per coconut tree every year.
He adopted the Save Soil–Cauvery Calling programme, which promotes multi-crop and multi-tier tree-based agriculture.
This raised his farm's soil organic carbon content from
0.5% to
1.56% over seven years.
His farm now grows over
14 crops, including nutmeg, pepper, banana, and turmeric, earning
Rs 2.5–
3 lakh per acre annually.
He also survived severe drought, including the 2017 crisis, by using mulching and rainwater harvesting pits.
Therefore, the described farmer is Valluvan, not any of the other listed names.
Answer:Valluvan (Option B).
