Climate induced events exacerbate food production and distribution risks, posing a threat to global food security. Though many studies focus on farmer adaptation to climate change, there are few studies of actors in the middle of agricultural value chains such as traders, logistics providers, and processors. The activities of these actors, referred to as the ‘hidden middle’, are key determinants of the prices received by farmers and the price and quality of food products for consumers. We explore how climate events and risk perceptions affect the adoption of value‐adding and damage control strategies among maize traders in Nigeria, Africa’s largest economy and most populous country. We find consistent evidence that climate events and climate risk perception discourage the adoption of value‐adding practices including storage. This potentially affects the availability and price of maize for consumers (household and industry) in the lean season. However, once traders store maize, climate risk does not affect the adoption of damage control, but training and social networks do. These findings suggest that actors in the midstream of food value chains are responding to climate change and more attention needs to be paid to these actors to maintain the availability of affordable and safe maize products throughout the year. There is also a need for strategies to reduce the risks of trading activities due to climate change.

作物价值链中游的气候风险和技术采用：尼日利亚玉米商人的证据

气候引起的事件加剧了粮食生产和分配的风险，对全球粮食安全构成了威胁。尽管许多研究集中在农民对气候变化的适应性上，但很少有研究涉及农业价值链中的参与者，例如商人，物流提供者和加工者。这些行为者的活动被称为“隐藏中间人”，是决定农民收到的价格以及消费者的食品价格和质量的关键决定因素。我们探讨了气候事件和风险感知如何影响尼日利亚，非洲最大的经济体和人口最多的国家的玉米贸易商对增值和损害控制策略的采用。我们发现一致的证据表明，气候事件和气候风险感知不利于采用包括存储在内的增值做法。这可能在淡季影响消费者（家庭和行业）的玉米供应量和价格。但是，一旦贸易商储存了玉米，气候风险就不会影响采用损害控制，但是培训和社交网络却会影响。这些发现表明，食品价值链中游的参与者正在对气候变化做出反应，需要更多地关注这些参与者，以保持全年可负担和安全的玉米产品的供应。还需要减少气候变化引起的贸易活动风险的战略。这些发现表明，食品价值链中游的参与者正在对气候变化做出反应，需要更多地关注这些参与者，以保持全年可负担和安全的玉米产品的供应。还需要减少气候变化引起的贸易活动风险的战略。这些发现表明，食品价值链中游的参与者正在应对气候变化，因此需要更多地关注这些参与者，以保持全年可负担和安全的玉米产品的供应。还需要减少气候变化引起的贸易活动风险的战略。
