Abstract

This study aims to estimate main food water productivity based on crop water use and subsequently aimed to analyze the total factor productivity growth using non-parametric Data envelopment analysis-Malmqist index (DEA-MI) methods. The secondary panel data from 2000-2015 regarding climate data, main food harvested areas, and main food production were applied. The results showed that paddy water productivity was in the range of 0.290 to 0.930 kg rice m-3 and corn water productivity was in the range of 0.553 to 1.590 kg kernel m-3. Based on DEA-MI single input-single output analysis, the average index of paddy water total factor productivity (PWTFP) was 1.014 with the average growth of efficiency change (EFC) index was 0.992, and technological change (TEC) index was 1.062. Belu district has the highest PWTFP growth. The average growth index of corn water total factor productivity (CWTFP) was 1.008 with the average growth of EFC index was 0.985 and TEC index was 1.023. Based on DEA-MI multi-input-multi output analysis, the average main food water total factor productivity (FWTFP) growth index in which the aggregate of paddy and corn water productivity was 1.014 with the average EFC index was 0.994 and TEC index was 1.020. During the period, there was a decrease of FWTFP, EFC dan TEC indices by 19.16%, 8.03%, and 12.10% respectively. Kupang municipal as the smallest food producer has a better FWTFP growth index. Furthermore, the increase of crop water productivity in the area like The West Timor is strongly advised through the increasing of production techniques.
