The impact of irrigation water pressure on grain growers'productive adaptation behavior
Non-agriculturalization of water resources squeezes out agricultural water and intensifies irrigation water pressure,resulting in losses in grain production and a decline in crop yields.Farmers must take adaptive measures to prevent and resolve agricultural water risk.Based on survey data from 14 cities in Shandong Province,we use the Double-Hurdle model to explore the effect,mechanism,and heterogeneity of irrigation water pressure caused by non-agriculturalization of water resources on grain growers'behavior of productive adaptation.The research shows that irrigation water pressure can significantly promote the decision-making and adoption intensity of grain growers'behavior of productive adaptation.From the perspective of management scale and farmers'livelihood heterogeneity,the impact of irrigation water pressure on large-scale farmers'decision-making and small-scale farmers'adoption intensity is great.The impact of irrigation water pressure on decision-making of part-time farmers(whose livelihoods are with little agriculture),part-time farmers(whose livelihoods are agriculture and with little some other)and pure farmers decreases successively,and the impact on the adoption intensity is manifested as pure farmers＞part-time farmers(whose livelihoods are agriculture and with little some other)＞part-time farmers(whose livelihoods are with little agriculture).The analysis of the action mechanism indicates that risk perception plays an important role in the relationship between irrigation water pressure and grain growers'behavior of productive adaptation.Therefore,we should promote the construction of farmland water conservancy facilities and the effective supply of adaptive technology and information.It is also necessary to design differentiated technology promotion strategies for farmers with different scales and livelihood types,to promote water-suitable and efficient development of agriculture.
