Originally, it was written as drought (雃 is the god of drought). Natural disasters include those that bring destructive damage in a short period of time, such as storms and tornadoes, and those that cause damage due to long-term abnormal weather, such as droughts, lasting from one month to several months. Droughts, also called droughts, were a major cause of agricultural disasters, but in recent years, agricultural damage in Japan has decreased due to the development of water irrigation facilities, and it has even become said that ``there is no poor harvest in a drought.'' On the other hand, as the population increases, the problem of shortages of drinking and industrial water has become more serious, and it is now often called ``katsusui.''

本来は旱魃(魃は旱(ひでり)の神)と記す。自然災害の中には,暴風雨や竜巻などで短時間に破壊的災害をもたらすものと,干ばつのように1ヵ月から長い時は数ヵ月に及ぶ長期の異常気象によって災害が起こるものとがある。干ばつは日照りともいわれ農業災害を起こす重要な原因であったが,近年は水利灌漑施設の発達によって日本では農業被害は減少し〈ひでりに不作なし〉とまでいわれるようになった。一方,人口の増加にしたがって飲料・工業用水不足の問題が深刻化して,渇水と呼ぶことが多くなってきた。
