This study is based on LINGO Optimizer and scenario analysis to evaluate the feasibility of Taiwan''s food self-sufficiency, population growth in a different assessment of the need to develop new water resources in order to achieve sustainable food and water may cost, and discuss the future population and food price trends, made for self-sufficiency target market feasibility assessment, feasibility assessment of agricultural land, water resources feasibility assessment, new water resources assessment and concluded that Taiwan was made after a comprehensive assessment of the future adaptation in response to the food crisis policy and strategy.
The researcher collects statistical data related to food in Taiwan over the past decade, including demographic trends, the supply of rice and grain and the area of rice production per unit area of irrigation water, etc. to estimate the amount of water to achieve the goal of Taiwan''s food self-sufficiency. Then calculate the most optimal cost of the program about the construction of new water reservoir (21.3 NT. / tons), resurgent water (20 NT. / tons), desalination (30 NT. / tons) and rainwater collected system (10.7NT. / tons).
Analyzing the literature, the researcher finds that food self-sufficiency can be achieved in Taiwan. The priority is to complete the projects of nascent water resources and the most important task of those projects is water desalination. However, it requires huge funds to develop. Management of sustainable food and water are very important tasks, but the government has not awarded that. In addition to developing new water resources to enhance the value of rural areas, the supplement of the projects, such as changing Taiwanese’s eating habits and stimulating the quantities of crops to increase food self-sufficiency rate in Taiwan.
