Evaluation of Irrigation Cooperatives Situated in Izmir Province by using Data Envelopment Analysis

摘要

Considering the enlargement of agricultural areas, irrigation efficiency should be increased to obtain the sustainable use of limited water resources. In this study 13 irrigation cooperatives situated in Izmir province of Turkey selected and visited to evaluate their performance. To make this, Data Envelopment Analysis has been used. This analysis is a linear programing technic to determine the relative efficiency of decision making units (DMU) (in this study irrigation cooperatives). In this study, the input oriented DEA model has been used to focus on the efficient use of irrigation water. The objective of the analysis has been to determine where the application of water is the most profitable. While evaluating the performance of cooperatives irrigation water volume (m3) and total irrigated area (ha) have been used as input, and financial agricultural gain (TL) has been used as an output. In addition to this, irrigation water loss of each irrigation cooperative has been calculated by subtracting irrigation water amount from projected water amount by using DEAP software. The results have provided the efficiency scores of irrigation cooperatives and determined which ones have been the most efficient. DEA is a useful analysis to determine irrigation performance of cooperatives situated in ?zmir province of Turkey.
