This document discusses conservation agriculture (CA) as an approach for climate change adaptation and mitigation in East Asia and the Pacific region. CA involves minimal soil disturbance, permanent organic soil cover, and crop diversification. It provides benefits like reduced costs, increased profits and food security while preserving resources and the environment. CA helps increase farms' resilience to climate change through practices like crop rotations and soil cover that improve drought tolerance, water retention, and resistance to heavy rain and frost. The document reviews the global history and adoption of CA, and argues for supportive policies and investments to accelerate its adoption.
