Abstract:
Calculation of agricultural water productivity in order to optimize the management of water resources and reduce the water consumption to sustain and improve food security for the coming generations is essential. Due to the limited availability of field data, spatial and temporal quantification of water productivity is very time and cost consuming, especially at regional scale. In this context remotely sensed data are valuable and promising source of information for quantify the water productivity. The main goal of this paper is to introduce the developed software based on the WATPRO model and remotely sensed data for benchmarking water productivity with minimum input requirements. Output of this software were evaluated against the estimated water productivity in 8 wheat fields in the Jiroft plain, located in the south of Iran. Assessing the accuracy of the software’s results with the measured water productivity at field show that this software perform well for estimation and mapping water productivity with an RMSE and correlation coefficient of 0.16 kg/m3 and 85% respectively. Also results show that the highest and lowest water productivity for wheat in this area is 0.4 and 0.8 kg/m3, respectively and the average of water productivity in the study area was estimated around 0.5 kg/m3.
