Agriculture is the sector most vulnerable to climate change. In recent years, the frequency of extreme weather events caused by climate change has increased, and disasters have directly affected crop production and the stable supply of agricultural products. Therefore, effective agricultural disaster prevention systems must be established and strengthened. We integrated meteorological information and crop characteristics to develop disaster prevention strategies for predisaster, peridisaster, and postdisaster stages. The aim was to strengthen the autonomous disaster prevention capabilities of farmers to ensure their profitability and mitigate the impacts of crop disasters. Disaster prevention information should be disseminated through the provision of refined forecasts and early disaster warning information through information platforms and applications. In sum, this paper introduces an agricultural disaster prevention system applied to disaster management in the agricultural sector through cross-disciplinary cooperation to establish an early crop disaster warning system.
