Due to the vulnerability and exposure of agriculture, farmers' adaptive strategies to climate change are important to food security and sustainable environment development. However, a systematic review is still absent, though there are many studies about farmers' adaptations to climate change, and few studies discuss their potential impacts on climate change. This article analyses farmers' adaptation strategies and their heterogeneities across regions in China via a systemic literature review. Then we also discuss possible driving factors of these adaptations and their potential impacts on greenhouse gas emissions. We follow the updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines to identify and screen publications. A total of 448 relevant records were identified from the Web of Science, Elsevier ScienceDirect, and China National Knowledge Infrastructure (CNKI). We include peer-reviewed publications focusing on farmers engaged in crop farming in China, with survey data and specific adoption ratio analysis of adaptations to climate change. After screening, 27 articles were finally analysed. Our results show that crop variety management, rescheduling farming, increasing production inputs, increasing irrigation, and crop structure management are prevalent strategies reported in the existing literature. However, sustainable adaptations such as improving farmland's ecological environment and agronomic water-saving irrigation gain less attention. Besides, farmers in northern China adapt to climate change more actively compared to their counterparts in southern China. Moreover, some adaptations with high adoption ratios, such as increased chemical inputs, might increase greenhouse gas emissions and accelerate climate change. Our findings have important implications for food security and sustainable agricultural development.
