The article highlights the transformation of previously fallow lands in the Tangail district of Bangladesh, now cultivated for various crops, particularly groundnut, due to their location between the Jamuna and Dhaleshwari rivers. These 'char' or sandy lands, which were once unproductive, have become profitable for local farmers and the ultra-poor, requiring less labor and no irrigiation or chemical inputs. The shift towards groundnut cultivation has significantly increased, covering 2,804 hectares this year, a doubling from the previous year, leading to substantial profits and self-sufficiency for the farmers. The Department of Agriculture Extension in Tangail has supported this initiative, with groundnut being sold at a profitable price of Tk 70-75 per kg in the local market.
