LIVELIHOOD VULNERABILITY AND INFLUENCING FACTORS OF RETIRED FISHERMEN BASED ON THE LVI-IPCC FRAMEWORK——A CASE STUDY OF HUNAN AND HUBEI PROVINCE
After the implementation of fishing ban in the Yangtze River,the retired fishermen lost their original means of livelihood and were in a relatively vulnerable state of livelihood.Based on the livelihood vulnerability(LVI)research framework proposed by the Intergovernmental Panel on Climate Change(IPCC),this paper constructed an assessment index system for the livelihood vulnerability of retired fishermen in the Yangtze River Basin.The vulnerability of the livelihood of the fishermen was measured,and the characteristics of the retired fishermen of each livelihood vulnerability levels were ascertained through the classification results of the Jenks natural break classification method.The linear regression model was further used to analyze the factors affecting the livelihood vulnerability of the retired fishermen and the contributing factors were analyzed within Shapley value decomposition method.The results showed that:(1)There was the state of livelihood vulnerability of retired fishermen in the study area,and the vulnerability of retired fishermen in Hubei was slightly higher than that in Hunan due to the influence of the job market and the limitation of their own livelihood capital.(2)Retired fishermen which was classified into levels of high,medium and low livelihood vulnerability showed different relative characteristics in the unidimensional livelihood vulnerability index.'High level'group showed'high exposure,low adaptation,high sensitivity','Medium level'group showed'medium exposure,medium adaptation,medium sensitivity',while'low level'group showed'low exposure,high adaptation,low sensitivity'respectively.(3)Gender,age,education level of householder,household income,and livelihood diversity had a significant impact on the livelihood vulnerability of retired fishermen.The characteristics of householder contributed most to livelihood vulnerability.Therefore,it should establish a dynamic follow-up mechanism for retired fishermen,enhance risk prevention capabilities,focus on vulnerable livelihood groups,and reduce exposure levels;and optimize the livelihood structure of retired fishermen,strengthen livelihood capital construction,and enhance adaptability;as well as ensure the implementation of employment promotion work,increase the stability of employment for retired fishermen,enhance their ability to resist risks,and reduce sensitivity.These measures may mitigate the livelihood vulnerability of retired fishermen in the Yangtze River Basin to some extent.
