This study investigates to determine whether the satellite image(SI) would be beneficial for Korean agricultural outlook in terms of technical and economic concerns by surveying trend of SI technological development and selected international examples of utilizing SI in the field of agricultural sector.
Many developed countries including the United States and European Union(EU) have used SI for producing agricultural statistics and outlook since the late 1970s. In Korea, some government institutes encompassing Rural Development Administration(RDA), the National Agricultural Products Quality management System(NAQS), and the Ministry of Forestry is utilizing SI for their works. As the SI technology is developed further, the SI will be widely used in the field of agricultural sector both domestically and internationally.
It is expected that an information on agricultural production area obtained from SI will improve the accuracy of agricultural outlook and its credibility. It may also reduce the cost for agricultural outlook. The SI would be powerful for checking changes in agricultural production area resulted from climate shock and government policy. Furthermore, the SI would be used for analyzing the situation of foreign agricultural production including North Korea and China.
In light of the current status of SI technology development in Korea, the cultivation area and yield would be determined from the SI for some products including rice. However further studies need to be implemented for adapting SI for specific purposes. Many lessons relating to SI are to be solved; burden of initial cost and lack of appropriate manpower handling SI.
In order to introduce SI for producing agricultural outlook information, i) step by step approach by which detailed information strategic planning(ISP) and about three-year pilot projects should be implemented is needed, and ii) each institute involving utilization of SI needs to cooperate for maximizing project's efficiency.
