The challenge of climate change adaptation and mitigation
Is more agricultural intensification enough?
Climate drives 32-39% of yield variation
Our systems are sensitive to climate, not resilient to it

Drought tolerant maize can increase yields 20-30% in dry conditions

Safe Alternate-Wetting-and-Drying (AWD)
30% water
20-50% GHG
Without compromising yield
• Keep flooded for 1st 15 days and at flowering
• Irrigate when water drops to 15 cm below the surface

The transition to CSA will require major shifts
• Agricultural intensification and productivity is not enough• trade-offs with adaptation (>half of time)• mitigation co-benefits are substantial, but not enough to
meet the 2 °C target• Need more practices with joint adaptation-productivity
outcomes• And need more transformative mitigation practices (2.5-5x)• Finance, capacity enhancement and technology transfer are
needed, but so is technology development for CSA
