Evolution of agricultural green development in the Yangtze River Economic Belt based on the perspective of reducing chemical products input and increasing output
The green transformation in agricultural production is an important research topic in the field of agricultural sustainable development.Based on the concept of agricultural green de-velopment and theoretical analysis in terms of the transformation path,this paper aims to exam-ine the major processes of the agricultural green development practices and assess the effects in reducing chemical products input and increasing agricultural output within the Yangtze River Economic Belt(YREB)in the past 20 years in combination of the methods of literature investi-gation,semi-structural interviews,questionnaire analysis and decoupling analysis.The results show that since 2015 the provincial-level regions within the YREB issued a set of policies relat-ed to the agricultural green development actions,which encouraged the farmers to replace the traditional chemical fertilizer with alternative and organic fertilizer,prevent and control the dev-astations caused by the diseases,insects and herbs with ecological measures,and reuse the agri-cultural residues in order to reduce the consumption of chemical fertilizer and pesticides and herbicides in agricultural production.Compared to the other regions in China,the YREB has a five-year lead in terms of achieving the great aims of zero growth and reduction of pesticide and chemical fertilizer use in agricultural production.Nevertheless,the current chemical fertil-izer and pesticide usage intensity in the YREB is still more than two times the international av-erage level.Although the chemical fertilizer and pesticide usage intensity in the downstream ar-eas of the Yangtze River is much higher than that in the upstream areas due to the differentia-tion in terms of multiple crop index and agricultural output density,the chemical fertilizer and pesticide usage intensity appears to gradually disconnect with the multiple crop index and agri-cultural output density because of the wide application of new technologies for agricultural green development.However,the ongoing agricultural green development agenda within the studu area still faces challenges,including the rising costs in upgrading the production technolo-gy and agricultural machinery and equipment and the severe difficulty in overcoming ageing is-sues and introducing or fostering young talents in agricultural sector.
