Studies show that greenhouse gas emissions will cause mean global temperatures to rise, leading to extreme weather patterns, less reliable crop yields, declining soil and water quality. About 90 percent of resource-poor farmers and consumers live in tropical environments, which are most vulnerable to climate change. By providing research-based knowledge and tools, CIMMYT helps farmers adapt, bringing food security and prosperity to these areas. In order to resist climate shocks and make better use of resources, CIMMYT works with public and private sector stakeholders to develop drought-resistant maize and wheat, complementing these new varieties with innovative farming practices. CIMMYT is an important contributor to the CGIAR Research Program on Climate Change, Agriculture and Food Security.
