Rice-crayfish coculture system and related developments at the age of climate-smart agriculture.

Agriculture affects and is affected by climate change. The development of climate-smart agriculture (CSA) is an effective way for agricultural production to cope with climate change. The rice-crayfish coculture system is a combination of the concept of climate-smart agriculture with the experience of traditional Chinese mixed crop-fish systems. This paper reviews the advantages and potential risks of rice-crayfish coculture with respect to climate, ecological environment and economic benefits, and summarises the successful management strategies and operation experiences during the implementation of this CSA practice in Qianjiang City. We also introduce various mixed crop-fish systems in China and suggest the potential of using wetland resources to develop mixed crop-fish systems and CSA. [ABSTRACT FROM AUTHOR]
