Recent changes in the climate of Korea show that the average rate of temperature increase is above 1.5°C, which is more than twice the global average temperature increase rate of 0.74°C, indicating that the rate of warming here is faster than that in other regions. These rapid climate changes demand a response strategy that include the development of adaptive varieties and cultivation techniques in agricultural ecosystems. The major rice producing regions of Gangwon-do are diverse and located in the central plains, northern plains, and east coast. To obtain the basic data necessary for resetting the cultivation methods to adapt to climate change, the yield quantity and yield components of rice were analyzed based on different ecological types and their transplanting period. In the central plain, the yield of early and middle maturing varieties increased with the increase in average temperature. The yields were not stable for the high-quality cultivation of mid-late varieties. However, the temperature rise did not affect the yields of the early, middle, and mid-late maturing varieties in the east coast region. In the central and northern plains, cultivation stability was confirmed only for the early varieties. Therefore, cultivation of the middle and mid-late varieties is not recommended for high-quality rice production and maintaining cultivation-stability. In the climate change scenario, quality and stability of cultivation are the priority factors that must be considered in rice cultivation areas.
