In sub-Saharan Africa (SSA) and Asia maize yields remain variable due to climate shocks. Over the past decade extensive progress has been made on the development and delivery of climate-resilient maize. In 2016 over 70000 metric tonnes of drought-tolerant maize seed was commercialized in 13 countries in SSA, benefiting an estimated 53 million people. Significant progress is also being made with regard to the development and deployment of elite heat-tolerant maize varieties in South Asia. Increased genetic gain in grain yield under stress-prone environments, coupled with faster replacement of old/obsolete varieties, through intensive engagement with seed companies is essential to protect maize crops grown by smallholders from the changing climates in SSA and Asia.
在撒哈拉以南非洲（SSA）和亚洲，由于气候冲击，玉米产量仍然不稳定。在过去十年中，在开发和提供抗气候玉米方面取得了广泛进展。2016 年，在 SSA 的 13 个国家商业化了超过 7 万吨耐旱玉米种子，估计有 5300 万人受益。在南亚开发和部署耐热玉米品种方面也取得了重大进展。在易受胁迫环境下提高谷物产量的遗传增益，加上通过与种子公司的紧密合作，加快更换旧/过时品种，对于保护 SSA 和亚洲小农户种植的玉米作物免受气候变化的影响至关重要。
