Climate Warming and Crop Management: A Comprehensive Analysis of Changes on Distribution of Suitable Areas for Double Rice

Understanding the effect of climate warming and technological progress on crop production systems is crucial for developing adaptation strategies. This study presents a methodological framework with which to assess suitability double rice cropping system in Southern China effects management its distribution. The results indicate that isolated have led northward westward expansions northern limits over past six decades an increase suitable areas by 4.76 Mha. Under management, medium- late-maturity changed significantly due increased accumulated temperature required caused varietal replacement planting date change, moved average 123 134 km southward, respectively. A combined scenario analysis indicated could offset push reducing overall area 1.31 Varietal other methods should also be appropriately considered addition develop locally adapted agricultural
