Assessing the regime-switching role of risk mitigation measures on agricultural vulnerability: A threshold analysis
Year: 2024
Type: article
Abstract: Vulnerability to agrometeorological disasters threatens agricultural production and food security, which calls for urgent risk mitigation measures. To examine the impact patterns of mitigation practices on reducing agricultural vulnerability and enhancing the functioning of agricultural systems, our study assesses the spatial-temporal characteristics of agricultural vulnerability to meteorological disasters from 2000 to 2021 at the provincial level in China. Identifying a dynamic trend of agricultural vulnerability and making use of a regime-switching framework, a Markov regime-switching model is employed to examine the changing regimes underlying the link between agricultural vulnerability and crop yields. More importantly, regime-switching roles of four different mitigation practices (i.e., irrigation, reservoir capacity, soil loss control, and drainage systems) in moderating agricultural vulnerability are evaluated using panel threshold regressions. Our results show that irrigation systems, water reservoirs, and soil loss control can be effective tools when it comes to mitigating agricultural vulnerability. With the above three measures, detrimental impacts of agricultural vulnerability on agricultural production can be reduced significantly when certain thresholds are hit. Additionally, non-linear relationships between mitigation measures and crop yields require authorities to pay considerable attention as concerns determining the effective scales of mitigation measures.
