"We calculated the distance of the cropland from shoreline as a coastal vulnerability index (CVI) of cropland to sea level rise and analyzed the characteristics of the distribution in the national context using the GIS data of 11 coastal municipal governments(Busan, Chungnam, Gangwon, Gyeongbuk, Gyeonggi, Gyeongnam, Incheon, Jeju, Jeonnnam, Jeonbuk, Ulsan) to evaluate potential impact of future climate change. Within 1km and 5km from the coast, cropland areas occupy is about 8.1% and 21.9%, respectively, which represents a much higher density of coastal cropland in the coastal bands. Especially, the coastal land zone between 100 m and 300 m shows the highest density with the distributional characteristics of field dominance for 0~200 m and paddy for 100~300 m, which can imply potential vulnerability of cropland to sea level impact in Korea. The cropland in the lowland (less than 10m elevation) occupies 23.2%(about 420,126 ha) of the those of 11 municipal governments, and among the lowland cropland 48% and 22% are located at within 5 km and 1 km from the coast, respectively. The coastal cropland in lowland shows a density peak at 200~300 m in most municipal governments except Gangwon, and Jeonnam contributes about 50% of lowland cropland within 500 m, whose province could be hotspot vulnerable to future climate change in Korea. In addition, Gyeongnam, Chungnam, Incheon, and Jeju also show moderate vulnerability." |
