World Journal of Innovative Research (WJIR) ISSN: 2456-8236, Volume-1, Issue-2, December 2016 Pages 25-28 25 www.wjir.org Abstract— The aim of the study was to assess performance of Ova Water User Association (OWUA’s) at Konya-Çumra province of Turkey. In research, as performance indicators, mainly water delivered, financial and production performance were analyzed. The results showed that annual water delivery per command and irrigated areas varied from 10360 to 13240 m 3 /ha and from 5958 to 7848 m 3 /ha, respectively. Irrigation ratio was between 132% and 192%. Unit area per staff was found as 0.0012 staff/ha. Money collection ratio was found as about 75 % for the average of last six years. The average production output or income for the year of 2014 was calculated as about 1210 $/ha. Although water shortage is the most important serious problem in our region, agriculture is still the single maximum water user sector even more than the world average of 70%. For sustainability of water supplies in region, efficient water use especially in agriculture can be strongly recommended. Index Terms—A Irrigation management, performance evaluation, water user association I. INTRODUCTION Irrigation can be defined as water application process in areas where the natural rainfall is insufficient to meet the whole crop water requirement. As we know that maximum yield can be obtained from the conditions where the soil moisture content is optimum during the vegetation period. Agriculture is the single maximum fresh water user sector as about 70% in the world [1] with up to 90% in some regions [2]. Water resources are declining in general [3] and are scant in nearby 80 countries having greater than 40% population of the world [4]. If that situation continues, by projections of 2030, water use for irrigation will increase around 14% [5]. Irrigation has the highest production cost in Konya Basin of Turkey since oil market price or water cost is high so water management based on water savings is strongly needed. Topak and Acar [6] reported that the agriculture with this present form has almost 90% of annual consuming water in Konya Basin of Turkey. The annual excess water use from groundwater reservoir is about 1.4 billion m 3 . Acar et al. [7-8] stated that the most important reason of excess water use from the groundwater reservoir is increase of irrigation lands in the favor of high water consuming crops such corn without considering the current water supply. Performance analyze is the most useful strategy to evaluate the efficiency of irrigation management. Cakmak et al. [9] reported that performance in many irrigation systems are far from the expectations due to İlker Cihan, IV General Directorate of State Hydraulic Works, Konya – Turkey. Bilal Acar, Department of Farm Buildings and Irrigation, Faculty of Agriculture, University of Selçuk, Konya-Turkey the some shortcomings such as deficiencies in design, construction, operation and maintenance works. There are different government and private organizations that are responsible for irrigation water management in Turkey, and one of them is water user association. Kıymaz [10] stated that main problems of water user associations are poor maintenance-repair works resulting from scarcity of machinery-equipment, deficiency in technical staff as well as very little or none farmer education. The efficiency of such associations can be determined by evaluation. Almost very little detailed studies have been cited in the literatures about the agricultural water management in our region, therefore, in this research, performance of OWUA’s was analyzed with detail, and some practical recommendations for better irrigation water management were outlined. II. MATERIAL AND METHOD The research was performed at irrigation areas, mostly irrigated by canals, of OWUA’s situated at Konya-Çumra province of Turkey. The study region, semi-arid climate with annual average rainfall of 300 mm, is about 1016 m above the sea level. The soil of region is alluvial origin having high lime contents with scant organic matter. The soils have no salinity as well as drainage problems such as water table [11]. Although there are 21 water user associations in Konya province of Turkey, OWUA’s has one of the biggest irrigation lands serving actively about 48000 ha farmlands. The data were obtained from records of OWUA’s as well as 4 th General Directorate of State Hydraulic Works (DSI) or other relevant organizations. In research, performance indicators of water delivery, financial and production performances were as follows: 1. Water delivery performance: Irrigation ratio=(Irrigated area (ha))/(Command area (ha)) x100 Total annual water delivery per command area=(Total volume of irrigation water inflow (m^3))/(Command area (ha)) Total annual water delivery per irrigated area=(Total volume of irrigation water inflow (m^3))/(irrigated area (ha)) 2. Financial performance: Revenue collection ratio=(Total service revenue collected)/(Total service due) x100 Unit area per staff member=(Total number of staff employed in association)/(Total command area served by the Performance of Ova Water User Association in Konya – Turkey İlker Cihan, Bilal Acar
