Abstract
Sustainable agricultural development is crucial for ensuring food security. However, climate change is increasingly affecting sustainable agricultural development. The purpose of this paper is to explore the impact of climate change on sustainable agricultural development and sustainable agricultural technologies for adaptation to climate change. It first analyses the trends and characteristics of global climate change and the characteristics of climate change in China, highlighting the negative impacts of the increased frequency of extreme weather events on agricultural production. Subsequently, the negative impacts of climate change on crop production, water resource use and soil are examined in depth, and the challenges of climate change to sustainable agricultural development are comprehensively assessed. Finally, some feasible sustainable agricultural technologies to cope with climate change are proposed. For example, by adjusting the agricultural layout, locally appropriate crops can be grown at the appropriate time and climate. In addition, new seedlings with high adaptive capacity can be cultivated, and emphasis can be placed on growing high-quality crop varieties that are resistant to drought, high temperatures, pests and diseases, and adversity. It is also possible to strengthen farmland water conservancy infrastructure to improve the stability of crop production and the adaptive capacity of crops, and to better cope with global climate change.
