Abstract

A preliminary assessment on the economic loss due to 1.0 m sea level rise induced inundation for the Kuwait is carried out. Kuwaiti coast of 500 km is divided into 162 segments and landward slope of the coast was assessed based on field measurements of coastal profiles. The prevailing cost of coastal land for all coastal segments are used for economic impact assessment. It is found that 29% of the coastal land in Kuwait is in the very low inundation cost category (less than 20,000 Kuwaiti Dinar (KD)/m of coast length (1 KD = 3.3 US $)); 19% is in the low inundation cost category (20,000 to 50,000 KD/m of coast length); 16% is in the moderate inundation cost category (50,000 to 100,000 KD/m of coast length); 14% in the high inundation cost category (100,000 to 200,000 KD/m of coast length) and 22% is in the very high inundation cost category (greater than 200,000 KD/m of coast length). The total inundation cost due to permanent inundation of coastal land area for 1.0 m sea level rise is 58.726 Billion KD (i.e., 193.8 billion US $), which is equivalent to 3.58 years of income for Kuwait due to crude oil export.

摘要

对科威特1.0m海平面上升引发洪水造成的经济损失进行了初步评估。科威特海岸 500 公里分为 162 段，海岸向陆坡度根据海岸剖面的实地测量进行评估。所有沿海部分的沿海土地的现行成本用于经济影响评估。据发现，科威特 29% 的沿海土地属于非常低的淹没成本类别（低于 20,000 科威特第纳尔 (KD)/m 海岸长度（1 KD = 3.3 美元））；19% 属于低淹没成本类别（20,000 至 50,000 KD/m 海岸长度）；16% 属于中等淹没成本类别（50,000 至 100,000 KD/m 海岸长度）；高淹没成本类别中的 14%（100,000 至 200，000 KD/m 的海岸长度）和 22% 属于非常高的淹没成本类别（大于 200,000 KD/m 的海岸长度）。海平面上升 1.0 m 造成沿海陆地区域永久淹没造成的总淹没成本为 587.26 亿科威特第纳尔（即 1938 亿美元），这相当于科威特因原油出口而获得的 35.8 年收入。
