稻虾生态种养技术会带来粮食数量安全问题吗?
Will the rice and crayfish co-culture techniques bring about food security issues?
摘要
Abstract
In order to explore the impact of rice and crayfish co-culture techniques on food security,based on the micro-survey data of farmers in the middle and lower reaches of Yangtze River in 2023,the relationship between rice crayfish co-culture techniques and national food security was empirically tested by using the treatment effect model.The results show that:1)Farmers'adoption of rice crayfish co-culture techniques will lead to a decrease of 43.975％in total rice yield,and rice and crayfish co-culture techniques will bring the problem of food security.2)The threat effect of rice and crayfish co-culture techniques on food security is not sustainable.With the continuation,normalization and standardization of rice and crayfish co-culture techniques adopted by farmers,the threat effect of rice and crayfish co-culture techniques on food security may gradually fade.3)The threat effect of rice and crayfish co-culture techniques on food security is heterogeneous in endowment conditions.The option of rice and crayfish co-culture techniques by small-scale farmers is limited effect on food security,while the adoption of rice and crayfish co-culture techniques by large-scale farmers has significant threat effect on food security.Compared with the farmers with non-farm employment and low household income,the farmers without non-farm employment and high household income adopted rice crayfish co-culture techniques,the techniques display a greater threat effect on food security.4)The age,education level,physical condition,land endowment and factor input of farmers are the important factors affecting the adoption behavior of rice and crayfish co-culture techniques and the total rice yield.Therefore,it is necessary to popularize standardized production,strengthen the supervision of rice and crayfish co-culture techniques and promote rice and crayfish co-culture techniques in a targeted way.关键词
