水肥一体化技术如何缓解农户生计脆弱性OACHSSCD

Promoting fertigation technology in poverty-consolidation areas is of great significance for enhancing farmers' livelihood resilience and preventing large-scale poverty relapse.Based on survey data from 504 farm households in the four prefectures of Southern Xinjiang,this study employs the vulnerability as expected poverty(VEP)approach to measure farmers' livelihood vulnerability and applies the ordinary least squares(OLS),propensity score matching(PSM),and instrumental variable(Ⅳ)methods to examine the impact of fertigation technology on farmers' livelihood vulnerability.The results indicate that:1)The adoption of fertigation technology significantly reduces farmers' livelihood vulnerability by 7.4％,and this finding remains robust after a series of robustness tests.2)Mechanism analysis shows that fertigation technology significantly improves farmers' production efficiency,reduces agricultural production risks,and optimizes cropping structures.3)Heterogeneity analysis shows that,compared with households in river-irrigated areas and areas with combined groundwater and river irrigation,the mitigating effect of fertigation technology on livelihood vulnerability is stronger for households in groundwater-irrigated areas,the effect is also stronger for households with land transferred in and households owning large-scale agricultural machinery than for those without.Accordingly,the promotion of fertigation technology should take into account the livelihood vulnerability characteristics of poverty-consolidation groups across different regions and adopt differentiated promotion strategies based on irrigation water sources,land management,and agricultural equipment conditions.Supporting irrigation facilities and agricultural socialized service systems should also be improved to expand technology coverage and improve the conditions for technology application among poverty-consolidation groups.
