Due to the recent water shortage caused by climate change, it is possible to evaluate water conservation effects through agricultural water policies and efficient water resource management by using the water footprint of rice fields,. In this study, we investigated the paddy rice water footprint under water management using the Agricultural Policy Environmental eXtender Paddy(APEX-Paddy) model corrected by applying the infiltration monitoring results. The water management scenario applied to the model is Continuously Flooding(CF), Intermittent Drainage(ID), Alternate Wetting and Drying(AWD). Considering only the consumption use, the green water footprint of CF, CF+ID, and ID+AWD were 405.1 ㎥/ton, 418.7 ㎥/ton, and 426.2 ㎥/ton, , and the blue water footprint were 589.0 ㎥/ton, 549.8 ㎥/ton, and 530.3 ㎥/ton, the total water footprint were 994.1 ㎥/ton, 968.6 ㎥/ton, and 956.5 ㎥/ton. In the case of water footprint including return flow, the return flow rate of CF, CF+ID, ID+AWD were 62.9%, 58.8%, and 56.0%. Also, over the past 30 years, the water footprint in the 2010s has increased from 13.7% to 16.9% compared with the 1990s. The results of this study are expected to be used as basic data for calculating the water footprint of rice fields and disseminating rice field water management technology for efficient management of agricultural water.
Abstract
Due to the recent water shortage caused by climate change, it is possible to evaluate water conservation effects through agricultural water policies and efficient water resource management by using the water footprint of rice fields,. In this study, we investigated the paddy rice water footprint under water management using the Agricultural Policy Environmental eXtender Paddy(APEX-Paddy) model corrected by applying the infiltration monitoring results. The water management scenario applied to the model is Continuously Flooding(CF), Intermittent Drainage(ID), Alternate Wetting and Drying(AWD). Considering only the consumption use, the green water footprint of CF, CF+ID, and ID+AWD were 405.1 ㎥/ton, 418.7 ㎥/ton, and 426.2 ㎥/ton, , and the blue water footprint were 589.0 ㎥/ton, 549.8 ㎥/ton, and 530.3 ㎥/ton, the total water footprint were 994.1 ㎥/ton, 968.6 ㎥/ton, and 956.5 ㎥/ton. In the case of water footprint including return flow, the return flow rate of CF, CF+ID, ID+AWD were 62.9%, 58.8%, and 56.0%.
