Abstract

This study examined the impact of climate change adaptation strategies on the welfare status of aquaculture fish farmers in Southwest, Nigeria. Multistage sampling procedure was used in the selection of 288 respondents. To account for selection bias due to both observable and unobservable factors where more than two options arise, the multinomial endogenous switching regression model was used to analyze the collected data. The empirical findings revealed that level of education brought about increase in the probability of adopting bore-hole construction, stocking time adjustment and embankment creation as adaptation strategies to climate change. Also, adoption of stocking time adjustment and embankment creation by the adopters increased food security index by 106.1 and 16.9%, respectively. Furthermore, adoption of stocking time adjustment in the adopters’ category reduced the poverty gap by 87.2%. It is, therefore, recommended that policies which promote adoption of climate change adaptation strategies (especially stocking time adjustment and bore-hole construction being the strategies with the highest impact) should be formulated since they are capable of increasing welfare of aquaculture fish farmers.

尼日利亚西南部养鱼户福利与气候变化适应策略:多项内生转换回归模型的应用

摘要

本研究考察了气候变化适应策略对尼日利亚西南部水产养殖渔民福利状况的影响。在选择 288 名受访者时使用了多阶段抽样程序。为了解释由于出现两个以上选项的可观察和不可观察因素导致的选择偏差,使用多项内生切换回归模型来分析收集的数据。实证结果表明,教育水平提高了采用钻孔施工、调整放养时间和筑堤作为气候变化适应策略的可能性。此外,采用者采取放养时间调整和筑堤措施,使粮食安全指数分别提高了106.1和16.9%。此外,采用收养者分类放养时间调整,贫困差距缩小87.2%。因此,建议制定促进采用气候变化适应策略的政策(尤其是放养时间调整和钻孔建设是影响最大的策略),因为它们能够提高水产养殖者的福利。
