Africa's food systems are among the most vulnerable sectors to climate risk. Unfortunately, numerous activities along food supply chains (production, processing, storage, marketing and consumption) are also important contributors to climate change. Despite the differential effect of climate events on activities along food supply chains and vice versa, most climate change perception studies in agriculture focus on producers, particularly crop farmers. This study adopts a value chain perspective to examine climate change perceptions among economic agents all along the maize-poultry value chain in Nigeria. We find that economic agents perceive those climate events that have a direct effect on their economic activity and this is not restricted to crop farmers. We also find that very few actors along the maize-poultry value chain believe that their economic activity negatively affects the environment and contributes to climate change. Though African countries might currently not be major contributors to climate change, this indicates a need for more awareness among economic agents about the effects of various agriculture-related activities on the environment and their contributions to climate change to encourage practices and technologies that can reduce agriculture's negative effect on the environment and contribution to climate change.
非洲的粮食系统是受气候风险影响最脆弱的部门之一。不幸的是，粮食供应链（生产、加工、储存、营销和消费）中的许多活动也是导致气候变化的重要因素。尽管气候事件对粮食供应链活动的影响以及反之亦然，但农业领域的大多数气候变化认知研究都集中在生产者，特别是农作物农民身上。本研究采用价值链视角，考察了尼日利亚玉米-家禽价值链中各个经济主体对气候变化的认知。我们发现，经济主体感知到那些直接影响其经济活动的气候事件，而这不仅限于农作物农民。我们还发现，在玉米-家禽价值链中，很少有参与者认为他们的经济活动会对环境产生负面影响并导致气候变化。尽管非洲国家目前可能不是气候变化的主要贡献者，但这表明需要提高经济主体对各种与农业相关活动对环境的影响及其对气候变化的贡献的认识，以鼓励采取能够减少农业对环境的负面影响和减少对气候变化的贡献的做法和技术。
