climate. Agricultural management practice in China may also change to optimise soil organic carbon sequestration . A study on projected irrigation requirements under climate change using a soil-moisture model for 29 upland crops in the Republic of Korea showed that water scarcity is a major limiting factor for sustainable agricultural production . In terms of drought, despite increasing future precipitation in most scenarios, crop-specific agricultural drought is expected to be a significant risk due to rainfall variability . On the other hand, a projected rise in water availability in the Korean Peninsula using multiple regional climate models and evapotranspiration methods indicates that it will likely increase agricultural productivity for both rice and corn, but would decrease significantly in rain-fed conditions . Thus, irrigation and soil-water management will be a major factor in determining future farming systems and crop areas in the country.
