“…It is necessary to accurately understand the biological characteristics of each crop to classify crop-specific hazardous weather by collecting information on the types of disasters, damage mechanisms, related hazardous weather and judgment criteria, and actual occurrences of each crop in the main production area. Universities and research institutions in South Korea and other countries have studied the weather conditions suitable for crop growth and the environments that may damage crops, including disaster-related studies and suitable cultivation site selection [12][13][14][15][16][17][18].…”

In recent years, the importance and severity of weather-related disasters have escalated, attributed to rising temperatures and the occurrence of extreme weather events due to global warming. The focus of disaster management has shifted from crisis management (e.g., repairing and recovering from damage caused by natural disasters) to risk management (e.g., prediction and preparation) while concentrating on early warning, thanks to the development of media and communication conditions. The Rural Development Administration (Korea) has developed the “early warning service for weather risk management in the agricultural sector” that detects weather risks for crops from high-resolution weather information in advance and provides customized information to respond to possible disaster risks in advance in response to the increasing number of extreme weather events. The core technology of this service is damage prediction technology that determines the overall agricultural weather risk level by quantifying the current growth stage of cultivated crops and the probability of possible weather disasters according to the weather conditions of the farm. Agrometeorological disasters are damages caused by weather conditions that can affect crops and can be predicted by estimating the probability of damage that may occur from the interaction between hazardous weather and crop characteristics. This review introduces the classification of possible weather risks by their occurrence mechanisms, based on the developmental stage of crops and prediction techniques that have been developed or applied to date. The accumulated crop growth and weather risk information is expected to be utilized as support material for farming decision-making, which helps farmers proactively respond to crop damage due to extreme weather events by providing highly reliable disaster forecasts through the advancement of prediction technology.

This study was conducted to find out the influence of elevated atmospheric CO 2 concentrations and air temperature on photosynthesis and fruit quality of 'Fuji'/M.9 apple trees and to investigate these to the effects of climate change during the last four years (2009)(2010)(2011)(2012). The treatments employed were: 'Ambient' (ambient temperature + ambient CO 2 concentration); 'High CO 2 ' (ambient temperature + elevated CO 2 concentration); 'High Temp.' (elevated temperature + ambient CO 2 concentration); and 'High CO 2 + High Temp.' (elevated temperature + elevated CO 2 concentration). The elevated temperature plots were maintained at 4 o C higher than ambient air temperature, while the elevated CO 2 plots were maintained at 700 µmol·mol −1 . Annual treatment period was applied from end of April to beginning of November for four years. Results showed that elevated CO 2 decreased stomatal conductance and leaf SPAD value, but increased photosynthetic rate, intercellular CO 2 concentration (Ci), and starch content of mesophyll tissue. In the vegetative growth, elevated temperature increased total number of shoot and total shoot growth per tree, but elevated CO 2 decreased average shoot length. In the fruit quality, elevated CO 2 increased soluble solid content, fruit red color, and ethylene production. In conclusion, elevated CO 2 increased photosynthetic rate of apples during the early growth, but effect of increased photosynthetic rate due to elevated CO 2 was decreased during latter growth stage. Elevated temperature, on the other hand, tended to decrease photosynthetic rate of apples during the early growth, but that tended to increase during latter growth stage. Both elevated CO 2 and temperature tended to decrease the degree of decreased photosynthetic rate due to each factor.
