Food and the environment are relevant to today's society, because the survival of a society requires food, and if a country does not maintain its own food security, then when the external environment changes, the food supply will Damage, which is not just a social issue, but a national security issue.

According to the statistics of the food self-sufficiency rate of external data, Japan, South Korea, Taiwan, Singapore, and Malaysia have less than 50% self-sufficiency. The source of food depends on imports, and prices will be affected by the exchange rates of various countries. In China, the United States, Canada, Thailand, and Vietnam, the food self-sufficiency rates are in the range of 100% to 200%. It can be known that the food in these countries can be fully self-sufficient, but there will be doubts about excess agricultural products in the first-tier industry. Then, with the self-sufficiency rate of food, how to ensure our own food supply is a problem that we need to consider, because food is always consumed one day, and how to make up for it is also a major problem. .

Before thinking about the solution, we can refer to the example of the Netherlands. In terms of food supply, the Netherlands adopts the strategy of developing precision agriculture. In order to promote the development of precision agriculture, the Netherlands is expected to invest 1.5 million euros to purchase satellite information, which will be provided to domestic farmers for free after analysis by research institutions or professional companies. This new mode of agricultural production management will combine the system Geographic Information System and Global Positioning System's two key core technologies are to collect and analyze data on various uncertain environmental factors such as climate, soil, pests and diseases, and finally achieve the objectives of precise crop management and monitoring and the improvement of agricultural production efficiency. The example of the Netherlands will be used because the Netherlands is a small country near the ocean. It is similar to the situation in Taiwan and can be used as a case of agricultural transformation.

As for what will happen if the self-sufficiency rate of food is not done well? An historical event was the Irish Famine, commonly known as the Potato Famine, a famine that occurred between 1845 and 1852. In these 7 years, the population of Ireland under British rule has fallen by almost a quarter; in addition to starving and sickly, this number includes about one million Irish who have migrated overseas due to famine.

The main reason why so many people starve to death is not because of insufficient food, but because they import large quantities of food from the Americas, and some of them are even transshipped through Irish ports; but hungry Irish people cannot afford these foods, and the assistance provided by the British government is very Scarcity results in a high proportion of Irish people starving to death. Economically unreliable, it will cause human disaster.

Finally, to solve the problem of food security, it is necessary to develop characteristic agriculture in the country, as in the Taiwan Agriculture Commission, to support small farmers, reform farmers' production organizations, and build a supply system based on production and marketing classes. Expand the scale of industrial settlements and adjust the industrial structure that was originally monopolized by disk vendors.

If each small farmer has a sufficient economic foundation, the self-sufficiency rate of food can rise, and the existing annual crop planting area of ​​750,000 hectares, compared with 275,000 hectares of rice and 78,000 hectares of miscellaneous grains. The output of 32,000 hectares of crops, 186,000 hectares of fruit trees, 15 million hectares of vegetables, 14,000 hectares of flowers, and 15,000 hectares of forage grass increased.
