This paper represents the first research to simultaneously study the agricultural water management and the influences on energy, food, and social security in Taiwan from 1980s. According to the survey, the average agricultural water use was 13.663 × 10 9 tons with standard deviation of 1.226 × 10 9 tons. The average value of agricultural water use percentage was 75.58% with standard deviation of 4.62%. The energy consumption in agricultural sector decreased year by year from 1983. The average energy consumption in agricultural sector was 130.841 × 10 9 L oil equivalent (OE) with standard deviation of 23 × 10 9 L OE. The percentage of agricultural gross domestic product (GDP) to total GDP decreased from 7.33% in 1981 to 1.83% in 2011. The magnitude and frequency of agricultural disasters increased severely in the past two decades. The loss of agricultural disasters account for 5% of the agricultural GDP and resulted in the fluctuation of crop production, farmers' family income, and social security. To lower the loss of agricultural disasters, the adaptation measures for agricultural water management, energy, food, and social security should ensure the stability of water, energy, and food supply.
