EXTREME DROUGHT,OPERATION SCALE AND FARMERS'ADAPITIVE BEHAVIOR——ANALYSISONTHE FARMERS SURVEY DATA IN JIANGHUAI WATERSHED
The adaptive behavior of farmers in face of natural disasters is the basis for public policy formulation,especially with the expansion of agricultural operation scale.Based on 342 farmer survey data,this paper examined the impact of operation scale on the adaptive behavior of farmers in the Jianghuai watershed,where an extreme drought occurred in 2022.The results were found as follows.(1) Operation scale had a positive impact on the adaptive behavior of farmers;(2) The impact of operation scale varied across different types of adaptive behavior,such that operation scale positively affected the adoption of new drought-resistant varieties and the enhancement of irrigation,while it negatively affected the adoption of seedling supplement and the adjustment of planting structure.Operation scale had no significant impact on the adjustment of sowing date;(3) The internal mechanism was that with the expansion of operation scale,the composition of farmers' resource endowment changed,and they tended to adopt capital-biased and technology-biased adaptive behavior.Moreover,the level of asset specificity of farmers increased,and they faced more sunk costs when adjusting their planting structure.In the context of frequent natural disasters,this research suggests that the government should further expand the scale of agricultural operations,strengthen the technical training and investment support for the main entities of scale operations to cope with natural disasters,so as to promote the construction of relevant social services.
