Spatial Distribution and Regional Characteristics of Meteorological Damages to Agricultural Farms in Korea

Abstract

Along with global warming, ever intensifying weather events have increased damages to agricultural farms and facilities. The objective of this study was to investigate the spatial distribution and regional characteristics of agricultural damages by extreme weather events. Agricultural disaster statistics provided by the National Emergency Management Agency were summed over for a 13-year period from 1998 to 2010 and used for the spatial analysis. Two indices of damage area ration and property damage per unit area were introduced to quantify regional agricultural damages. As the results, farm inundation accounted for the largest area primarily damaged by typhoons with heavy rainfalls. Most property damages to farm lands originated from farm erosion in the alpine regions by localized guerrilla rains. The two major causes of damages to greenhouse and livestock facilities were typhoon with strong wind and winter blizzards. Gangwon was the province of the largest property loss mostly from farm land erosion losses, followed by Gyeongnam, Jeonnam, and Chungnam where losses to greenhouse and livestock facilities were relatively greater. Property loss per unit area was also the greatest for the Gangwon province (4.91 M￦/ha), followed by Gyongnam and Chungnam of 2.20 and 1.50 M￦/ha, respectively. Unit loss for greenhouse and livestock facilities was 13.3 M￦/ha, approximately 13 times greater than that for farm land (1.06 M￦/ha). The study findings indicated the importance of reducing highland farm erosion and reinforcing farming facilities structures for agricultural disaster management.

Climatic yield potential of Japonica‐type rice in the Korean Peninsula under RCP scenarios using the ensemble of multi‐GCM and multi‐RCM chains

“…The limitation of the current study is the lack of consideration for other factors affecting rice production in the Korean Peninsula, such as agricultural damage caused by extreme weather phenomena (Song et al ., 2012; Shim et al ., 2013), the reduction of agricultural land due to urbanization (Lee et al ., 2012a), the increase of disease occurrence under global warming (Shim et al ., 2008b; Jeong et al ., 2014), the change in the beginning and ending times of the monsoon (Changma), the increase in the intensity of rainfall due to climate change (Hong and Ahn, 2015), and the improvement of species adapted to climate change (Ku et al ., 2014;Shin et al ., 2013). Thus, accounting for these factors in future studies will give a more reliable prediction of future rice production.…”

Estimating the Threshold Value of Disaster-Causing Snowfall by Region and Its Application to Regional Classification

“…또한, Y.J. Kim et al (2012)은 강원도 영동지 역의 종관 기압 패턴을 분석한 결과, 시베리아 고기압이 동해 쪽으로 확장하는 경우는 영동지역, 저기압 이동형은 영서지역에 피해를 유발한다고 분석했다. 또한, 평창과 강릉 은 다른 그룹의 지역에 비해서 24 hr 이상 연속관측 횟수와 5 cm 이상의 강설이 관측된 횟수가 다른 연구지역에 비해 상대적으로 많았다 (Fig.…”

“…대설로 인한 피해특성에 관한 연구 (Nam, 2003;Song et al, 2012;Myung, 2014) 등은 활발하지만, 지역별 기상재해 를 유발하는 대설의 임계값에 대한 체계적인 연구는 미흡하 다 (Cheon, 2017).…”

“…Nishiyama et al (2007)은 자기조직화지도 를 활용해 일본의 강수지역을 8개로 구분했고, Lin and Chen (2006)은 대만의 강수지역을 8개로 구분했다. 또한 Lu et al (2006) 대설 피해는 주로 비닐하우스에 많이 발생한다 (Song et al, 2012;Kim et al, 2018). 그러므로 본 연구에서는 우리나라 의 비닐하우스 발전 역사와 선행연구를 검토하고, 재해연보 에서 비닐하우스의 피해가 정량적으로 집계되기 시작한 1990년부터 최근 2017년까지를 연구의 시간적 범위로 설정 했다.…”
