| Abstract | Crop consumptive water use (CWU) is a key factor in sustainable agricultural water management. However, there has been rare discussion on the broader factors affecting CWU particularly in semi-arid region. The aim of this paper was to determine the West Timor main food consumptive water use (CWUFood), to model and to optimize the effect of socio-economy-environment on CWU and food production. This study applied a sixteen-year balanced climate and non-climate panel data. The estimated method is based on crop evapotranspiration by FAO-PM method. The modeling and optimization using response surface methodology (RSM). The results showed that West Timor traditional subsistence agriculture experienced fluctuation and increasing water consumed by main food during 2000 – 2015 that averaging reached 572 Mm3/year in which corn had consumed total water much higher than paddy. Model evaluation proved that a reduced quadratic model was robust. The amount of rainfall, farmer expenditure, district and part of their interactions had significant responses towards CWUFood and Food Production. In addition, the optimized result showed that by 25% reduction of CWUFood impacted on 33.18% reduction of maximum food production that equivalently with 111.22% increased from mean food production. |
