Abstract

Natural hazards frequently batter Bangladesh and cause damages to fisheries sector of the country. The main objective of the present investigation was to evaluate the effects of storm/tidal surge, waterlogging, cyclone, flood, drought and erosion on spatial distribution of damages and economic loss in fisheries of Bangladesh. Data were collected from existing literatures followed by scoring and attribute-wise maps were prepared using IDRISI3.2. The highest economic loss (US$ 17.65 million) in fishery sector was observed in Southern part and the least in hilly regions. The damages caused by natural hazards followed the order of storm/tidal surge > waterlogging > cyclone > flood > drought > erosion. About 21% areas of South and South-east Bangladesh were affected by high to very high storm/tidal surge. Very severe waterlogging problems were observed in 6.96% areas of the country. Moderate to high damages because of cyclone were found in about 11% areas in South and South-east Bangladesh. Moderate to high flooding problems were mostly prevalent in Central and North-east part of the country covering 15-19 per cent areas. Drought and erosion are less damaging to fishery sector compared to other studied natural hazards. Although exposure index to natural hazards is high, relative index to national economy because of damages to fisheries sector are low. Adaptive measures in coastal areas as a long-term strategy would be participatory construction of hard structures and reclamation/conservation of wetlands throughout the country including improved warning system could be undertaken for minimizing damages in fisheries sector of Bangladesh.

极端气候事件与孟加拉国渔业生产
自然灾害经常袭击孟加拉国,对该国渔业部门造成损害。本调查的主要目的是评价风暴/潮涌、内涝、旋风、洪水、干旱和侵蚀对孟加拉国渔业损害和经济损失空间分布的影响。从现有文献中收集数据,然后使用IDRISI3.2进行评分和属性映射。南部地区渔业部门的经济损失最大(1 765万美元),丘陵地区损失最少。自然灾害造成的破坏程度依次为风暴潮>内涝>气旋>洪涝>干旱>侵蚀。孟加拉国南部和东南部约21%的地区受到高至超高风暴/潮汐的影响。全国6.96%的地区出现了严重的内涝问题。孟加拉国南部和东南部约11%的地区受到飓风造成的中度至重度破坏。中至高度水浸问题主要集中在占全国15- 19%地区的中部和东北部。与所研究的其他自然灾害相比,干旱和侵蚀对渔业部门的损害较小。虽然自然灾害的暴露指数高,但由于渔业部门的损害,国民经济的相对指数较低。作为一项长期战略,沿海地区的适应性措施将是在全国各地参与建造硬结构和开垦/养护湿地,包括改进警报系统,以尽量减少对孟加拉国渔业部门的损害。
