The Use of Underground River Water On Creative Agriculture In Dry Land Karst Region

Abstract

Drynessis a phenomenonthat isoften foundinkarstareasinvariousparts of the world. Karst areahas verylimited surfacewaterresource availability. Surface water is only found in ponds where there are not many. Like most areas of karst, Pucung village Eromoko District of Wonogiri that located in Gunung Sewu karst region, have difficulty to get clean water for daily use. However, although dry on the surface, Pucung village has potential resources of underground water in the form of an underground river in Goa Suruh Corridor. This paper describes the use of these underground river water to develop creative agriculture in dry land on karst region in Pucung village.The lifting of underground river water from Goa Suruh corridor has successfully completed the issue of drought and simultaneously generate expenditure savings to buy clean water up to 1,500 %. Water use were developed not only for domestic use (drinking, bathing, washing) but also for productive activities that can increase family income by growing vegetables in polybag and catfish farming in tarp pool. Vegetable farming using polybags is suitable on dry land in the Pucung village because it is very efficient in the use of water.Meanwhile, catfishlivestockin thetarp poolin addition to morepractical, easy to applyin a limited areaand theproduction cost ischeaper thanpermanentpool.
