这项研究分析了盐度入侵对湄公河三角洲水稻种植的不利影响的感知数据。通过采访441个家庭的户主和几次焦点小组会议收集的数据被用来提供对当前适应或应对战略的理解，并从获得的见解中为管理这一日益增长的挑战提出建议。我们发现，大多数家庭都担心盐度入侵对他们的生计和未来应对能力的影响。一些战略已经失败，许多农民将难以在中期内适应。删失的广义泊松回归和负二项回归模型被用来识别和测试替代管理策略的有效性。结果表明，农民更倾向于修建堤坝作为防止盐碱化入侵的手段。我们的结论是，通过提供更多的信息和培训，可以提高农民支持堤防建设和改善的意愿。
This study analyses data on perceptions of the adverse impacts of salinity intrusion on rice farming in the Mekong River Delta. Collected via interviews with the head of 441 households and several focus group meetings, the data is used to provide an understanding of current adaptation or coping strategies and, from the insights gained, make recommendations for the management of this increasing challenge. We find that most households are concerned about the impact of salinity intrusion on their livelihood and their capacity to cope in the future. Some strategies are already failing and many farmers will struggle to adapt in the medium-term. Censored generalised Poisson regression and negative binomial regression models are used to identify and test the effectiveness of alternative management strategies. The results suggest that farmers have a preference for the construction of dykes as a means to prevent salinity intrusion. We conclude that farmer willingness to support the construction and improvement of dykes can be improved by providing more information and training.
