ABSTRACT

The purpose of this study is to examine the effectiveness of satellite images in detecting the areas of naked barley production in the South Jeolla Province. We also investigated the effect of climate change on the crop production through comparative analysis of naked barley production area and production statistics with climate data at multi-temporal time scale. The analysis found that the classification of naked barley fields extracted through satellite image and made as the number of naked barley cultivation areas did not exceed 10 percent of the statistical data. Climate data analysis showed that the greatest influence on the productivity of naked barley was the average temperature of the ripening stage and the impact of rainfall was relatively minimal. Taken together, these results suggested that changes in the yield of naked barley are occurring due to changes in temperature and precipitation in the study area. Therefore, it is believed that this research could serve as a key basis for solving food security issues due to climate change.
