Abstract:

Farmers’ cognition and risk perception of soil and water loss are the key factors influencing adoption willingness for soil and water conservation tillage technology in the Loess Plateau. Exploring the effects of the two factors is conducive to improve technology adoption, control of soil and water loss, reduce sediment into the Yellow River and improve ecological environment. Based on the survey data of 1237 households in the Loess Plateau, this paper analyzes the impact of farmers’ technology cognition and risk perception on willingness to adopt soil and water conservation tillage technology and the intergenerational differences by using stepwise regression and grouping regression. The results show that: (1) Technology cognition has a significant positive effect on adoption willingness, effect intensity of technology cognition on adoption willingness of new generations is greater than that of old generations for contour tillage, furrow and ridge planting, moderate or non-tillage, subsoiling, straw returning, stubble mulching and plastic film mulching. (2) Risk perception has a significant positive effect on willingness to adopt contour tillage and furrow and ridge planting, and the effect intensity is different between generations. Risk perception has a significant positive effect on willingness of new generations to adopt moderate or non-tillage, and on willingness of old generations to adopt subsoiling, straw returning, stubble mulching and plastic film mulching. (3) Risk perception plays a positive moderating role between technology cognition and adoption willingness. In willingness to adopt contour tillage, furrow and ridge planting, stubble covering and plastic film mulching technology, risk perception plays a stronger moderating role for old generations than for new generations. In willingness to adopt moderate or non-tillage, subsoiling and straw returning technology, risk perception plays a stronger moderating role for new generations than for old generations. (4) The control variables such as the age of householder, education level, family labor force, non-agricultural income proportion, actual cultivated land area, distance from the village to the town and the traffic convenience have significant differences on the willingness for new generations and old generations to adopt the soil and water conservation tillage technology.

Key words: technology cognition, risk perception, households, soil and water conservation tillage technologies, adoption willingness, intergenerational difference, the Loess Plateau
