In Korea, agricultural environment has been rapidly changed by several factors and the directions of agricultural policy of government have not been maintained by the sudden changes in recent years. The paradigm of agriculture policy is shifted from the maintenance and conservation of agricultural production to the increase of economic, social and ecological value based on agricultural profitability. The agricultural policy and production system are changed by following main social concerns; first the concern of the exhaustion of natural resources, second the quality of life is decreased by the physical and biological change of climate disturbance, third the deterioration of living environment by human activity and finally, the attention of food security by the unbalance and decrease of food production. Furthermore, in spite of low food (23%) and energy (29%) self-sufficiency, it would seem that the importance of the expansion and improvement of food production is not considered by agricultural policy makers. The foundation of agricultural production is collapsed and weakened because the policy makers decide to relegate the importance of food production to lower priority. Our present life style will be changed by the exhaustion of carbon energy. As a result, the production system of agricultural products will be improved and the price of the products will be increased. It is discussed how our agricultural environment will be changed with the surroundings, what factors, specially climate changes, will be considered to research pest management, and how the strategy of green pest management based on sustainable agriculture will be possible.
