Rameshbhai Patel, a farmer from Gujarat's Anand district, turned to sustainable agricultural techniques and adopted cow-based natural farming. He experienced a tremendous increase in sweet potato yield after converting to natural farming. Cow Based Natural Farming (CBNF) is a technique that puts cows and the farmer at the center of the agricultural ecosystem. This ancient technique makes it a priority to maintain the agro-ecology in order to make quality crop production a sustainable activity.
