North Korea has frequently suffered from extreme agricultural crop droughts, which have led to food shortages, according to the Food and Agriculture Organization (FAO). The increasing frequency of extreme droughts, due to global warming and climate change, has increased the importance of enhancing t...

SPI란 무엇인가? | McKee et al. (1993)에 의해 개발된 SPI는 세계기상기구(World Meteorology Organization)에서 권장하는 가뭄지수이며, 미국국립가뭄경감센터 (National Drought Mitigation Center, NDMC)에서 가뭄을 판단하는 가장 기본적인 지수이다. SPI는 보통 시간 단위를 3, 6, 9, 12개월로 설정하고, 시간 단위별로 강수부족량을 산정하여 각각의 용수공급원이 가뭄에 미치는 영향을 판단하는 지수이다(Kim et al. | |
해외의 가뭄피해 현황은? | 전 세계적으로 극심한 가뭄피해로 인해 가뭄 조기경보의 필요성이 대두되고 있다. 미국에서는 2012년부터 2015년까지 4년간 캘리포니아 지역에서 극심한 가뭄이 지속되었으며, 캘리포니아 농업식품기구 (California Department of Food and Agriculture, CDFA)는 캘리포니아 지역의 장기적인 가뭄으로 인해 농산물의 수확량이 감소하고 총 경제적 피해는 약 3조 원 가량의 피해가 발생했다고 하였다(CDFA, 2015). 우리나라 의 경우, 2014년 후반부터 가뭄이 심화되어 2015년에는 연간 강수량이 948. | |
일반적인 가뭄 해석 방법은? | 일반적으로 가뭄을 해석하기 위하여 가뭄심도, 빈도, 피해 면적과 기간의 영향을 고려한 가뭄지수를 이용하며, 국내의 경우 기상청, 한국농어촌공사의 농업가뭄관리시스템, 국가가뭄정보분석센터 등에서 가뭄 모니터링이 이루어지고 있다 (Kim et al., 2006; Nam et al. |
