This document discusses the challenges of climate change for global food security and the role of climate-smart agriculture. It summarizes the following key points: 1. Climate change is already causing crop yield losses in some areas and extreme weather events are expected to intensify in the future, threatening global food security. 2. Climate-smart agriculture promotes technologies, practices, and policies that help communities adapt to climate change, reduce greenhouse gases, and ensure future food security. 3. The CGIAR Research Program on Climate Change, Agriculture and Food Security is working with partners in various regions to research, promote, and implement climate-smart agriculture through activities like developing climate information services, insurance products, and policies to support resilient
