Objective: Increase agricultural production and productivity Targets: 2.5 millions farmers Means: improve rice and maize crops ( vouchers : improved seeds, inputs), stop residue burning, adoption of improved practises with better agronomic practises and better nutrient management Duration of carbon balance appraisal: 7+13 years
