Taiwan is surrounded by the sea, at the same time by the continental, oceanic climate and related topography of the impact of the complex variability of the weather environment, in terms of rainfall, more than 2,500 mm per year, About 2.6 times times the global average, which is supposed to be a water-rich country, however, due to the dense and uneven distribution of rainfall, mostly concentrated in the Meiyu period from April to October and typhoon season, so that the annual distribution of water per person is only 4,500 cubic meters (tons), the world average of 1/6 strong; by hydrological data, China is ranked 19th in the world, the lack of shortage, so Taiwan is not lack of rain but water shortage of countries.

　　According to the Water Conservancy Department of the Ministry of Economy, Taiwan's daily life, industrial and agricultural water consumption of about 18 billion cubic meters, in addition to direct water from the river, reservoir storage supply, the insufficient part of the groundwater supplement, but some areas of excessive extraction of groundwater, resulting in subsidence, seawater intrusion, quality degradation and other negative effects. Nearly 2/3 of Taiwan's water resources are used for agricultural irrigation, since agricultural water is more than 70% of the country's total consumption, and irrigation accounts for more than 90% of agricultural water. In recent years, the climatic environment changes frequently, the rainfall in eastern Taiwan increased in autumn and winter, but decreased in the southwest, and the number of consecutive rain days in the south was high, which often caused water shortage in spring and aggravated the impact and disturbance of the dry season on agricultural production. From the end of the year (103) to date (104), that is, due to the sudden decrease in rainfall and the shortage of reservoir volume, which causes serious water shortages, the government announced that 40,003, 000 hectares of rice should be stopped and fallow, and that the limited supply of water for industry and people's livelihood should be taken into account. Proper maintenance and increasing expenditure is the subject to be confronted with in the rapid economic development and sustainable industrial operation.

Increasing expenditure of water resources

To address the growing scarcity of water resources, improvements can be made to existing reservoirs and pollution, as well as new reservoirs, recycling of waste water and desalination, in which more than 120 countries worldwide use seawater desalination technology to obtain fresh water as an alternative source and to increase the number of autonomous water sources. The existing seawater desalination technology in our country is mainly used in the outlying islands, but its treatment plant has a small economy and high unit construction cost, so we should actively develop these inexhaustible seawater in Taiwan Island, and then increase the amount of water available to the people.

World Magazine (2014.06.11) once reported: "Two-thirds Land is desert, 30 days a year of rain, the weather is hotter than Taiwan." Why is it that no one in Israel is saving water this year when it faces its worst drought in 90 years? 」。 It turns out that Israel is short of rain but does not lack water, and that, in addition to large amounts of output water technology to earn high foreign exchange, it is also widely used desalination seawater, as well as the recovery of waste water to supplement, of which more than 80% of reclaimed water for agricultural irrigation Brass (Simcha Blass), the father of Israel's water resources, it found that the bottom of the water pipe because of the leak but nourishing the tree, so the invention of drip irrigation technology, water efficiency of up to 95%, so far various types of drip irrigation systems have been widely used in agricultural production worldwide, the water resources to save, help a lot.

Promotion of dryland irrigation subsidy scheme

In order to promote the conservation of agricultural irrigation water, in response to the current and future shortage of water, the Agricultural Committee of the Executive Yuan began in 72, that is, to actively guide farmers to set up pipeline irrigation and fertilization equipment to promote dryland irrigation water technology, improve the quality and competitiveness of agricultural products, as well as the effective use The planning Committee for the promotion of dryland irrigation facilities is co-ordinated by the Water Conservancy Association, Irrigation and Water Conservancy will be responsible for the implementation, and the annual notice of the application of the relevant provisions and subsidies, including the end of the pipeline irrigation system (divided into perforation tube, sprinkler, micro-spray, drip irrigation, etc.), water control facilities (Power equipment: motors, engines), pumps Storage facilities: Limited RC, reinforced brick, aluminum alloy, stainless steel, plastic and other materials of water storage tanks; control facilities: automatic control, pesticide mixing, fertilizer mixing and other control facilities. The scheme grants the first applicant as the priority, and each applicant's maximum annual subsidy amount must not exceed NT $300,000, the subsidy benchmark is based on the system cost 49% as the principle, the farmer own burden 51%, the detailed stipulation please concludes examination complainant the COA (104) January 8 Amendment promulgated " To popularize the main points of dry line irrigation operation, or to contact the local water conservancy and its workstations.

After 30 years of grieving, the planning of dryland irrigation facilities The guidance farmers set up a total area of about 40,000 hectares of pipe irrigation, the beneficiary households reached 50,000 households, and the application of the type from the early perforated tube, sprinkler system, the evolution to the current more advanced drip irrigation, micro-irrigation equipment, the operation of the use of a single irrigation function to promote fertilization, spraying, Anti-frost, such as multiple-standard, at present, especially in irrigation, fertilization and use the most type; control mode is also controlled by manual control progress, and even with environmental climate monitoring to adjust the amount and frequency of irrigation fertilization, fully achieve the goal of precision management. The piping system can improve the uniformity of irrigation and provide irrigation demand in time with the adjustment of the perinatal period, and can reduce the transportation and evaporation loss of irrigation water, and the water reaches 30~50% above the irrigation methods such as traditional flooded irrigation, irrigation, furrow ditch and so on.

Golden Corridor promotes water-saving irrigation system

"Golden Corridor" is not only a short term of a plan, but also a specific region, the Department of Agriculture will promote the Executive Yuan "golden Decade-National Vision" policy plan, with "Lohas agriculture" as the main axis, with the "economic momentum to promote the plan" of the Comprehensive Agricultural Action plan, called " Golden Corridor Agriculture new plan and Action Plan "; and to the south of Zhanghua County and Yunlin County high-speed rail 3 kilometers (that is, the orbital center about 1.5 km) of the narrow corridor within the scope of agricultural land, counseling farmers to adjust the cultivation of low water consumption of crops, the use of scientific and technological water-saving production, and the introduction of new farmers, new technologies to promote the development of
