Recently, drought and rainy season are getting more serious. It is getting hard to forecast about drought because drought frequency is getting shorter than before. Drought is threatening our life, especially damage of drinking water and agricultural water were causing problem about farming program which is getting extensive and when all is said and done This is absolutely big problem that drought is bring about insufficiency of supplies. In 2009 (winter) and 2012 (summer). The other big issue of Taebaek is decrease in products of Highland Agricultural caused by the drought. Agricultural damage of scale was estimated approximately 1.16 billion won due to drought in Taebaek-si (estimation of the Drought damages with the case of Taebaek , Choichoong-ik, 2010.08) Highland chinese cabbage Which is the most important agricultural product in Taebaek-si account for 95.9%(37,164 ton) of all agricultural production of Taebaek (38,757 ton) and account for 86.6%(978ha) of all gross area(1129.6 ha)(statistics yearbook of Taebaek 2012). This is account for 18% all Highland chinese cabbage agricultural production of all the country(177,708ton) and account for 21% all gross area of all the country(5,495ha)(Korea Rural Economic institute, Agricultural Outlook Center 2012). For this reason, Chinese cabbage of Taebaek-si is tropical agricultural product and is in charge of supply cabbage definitely. It is considered that if small scale rainwater harvesting system would be installed in highland agriculture area, it could reduce damage of drought at low cost and damage of cabbage would be decrease by system. For this study, We have researched regarding current status of Small Scale Rainwater Harvesting System of Highland Agriculture area in Taebaek- si and have compared with the amount of damage and installation cost in case of drought for the beneficial effects of Small Scale Rainwater Harvesting System, flexible supply of water and damage minimization of agricultural products. This research was supported by a grant(12-TI-C01) from Advanced Water Management Research Program funded by Ministry of Land, Infrastructure and Transport of Korean government
