摘要

背景:阿萨姆邦被认为是洪水多发邦,因为这种自然灾害几乎每年都会造成破坏性局面。本研究在阿萨姆邦的 Dhemaji 县进行,该县被列入洪水危害指数较高的地区。选择该地区是为了了解洪水对农业生产经济损失的影响,并研究该地区受洪水影响的农民所采取的缓解策略。方法:采用多阶段随机抽样技术从该地区挑选受洪水影响的农民。通过计算研究地区的农作物损失、农业资产损失和牲畜损失,估算洪灾对农业生产造成的经济损失。在计算洪灾造成的农作物经济损失时,对洪灾和非洪灾情况进行了比较。采用亨利-加勒特排序法对农民面临的问题进行排序。结果:结果显示,洪灾情况下农作物生产的净收益(第一组为 1032.44 卢比/公顷,第二组为 3830.99 卢比/公顷)低于非洪灾情况下的净收益(第一组为 7051.30 卢比/公顷,第二组为 8330.08 卢比/公顷)。大多数受访者(79.17%)认为迁移是保护他们免受洪灾损失的最佳应对机制。

Assam Flood and Financial Loss in Agricultural Production: A Study on Mitigation Strategy Adopted by the Farmers of Dhemaji District
Background: Assam is considered as a flood prone state, as this natural disaster creates devastating situation almost every year. The study was conducted in Dhemaji district of Assam which is in the list of highly flood hazard index. The district was selected to know the impact of flood on financial loss for agricultural production and to study the mitigation strategy adopted by the flood affected farmers in the district. Methods: For that a multistage random sampling technique was adopted to select flood affected farmers from the district. Financial loss for agricultural production due to flood was estimated by calculating financial loss for crop loss, agricultural asset loss and livestock loss for the study area. Flood situation and Non flood situation was compared while going for calculation of financial loss for crop due to flood. Henry Garret ranking technique was adopted to rank the problems face by the farmers. Result: The result reflected that net return from crop production was recorded to be less (Group I 1032.44Rs/ha and Group II 3830.99 Rs/ha) in flood situation than the non-flood situation (Group I 7051.30 Rs/ha and Group II 8330.08 Rs/ha).Total financial loss due to crop loss, asset loss and livestock loss was found to be high for size group II farmers (Rs 39094.33) then the size group I (Rs 36643.40). Majority of the respondents (79.17 per cent) preferred migration as the best coping mechanism to protect them from flood loss.
