Varieties: How can climate-smart varieties be delivered quickly and cost-effectively to smallholders? Farm management: What are key lessons on the contributions from soil and water management to climate risk reduction and how should interventions be prioritized? Value chains: How can climate risks to supply and value chains be reduced? and Scaling up: How can most promising climate risks reduction strategies be quickly scaled up and what are critical success factors? Readers who will be interested in this book include students, policy makers, and researchers studying climate change impacts on agriculture and agricultural sustainability.
