Towards Monitoring Waterlogging with Remote Sensing for Sustainable Irrigated Agriculture

Waterlogging is an increasingly important issue in irrigated agriculture that has a detrimental impact on crop productivity. The above-ground effect of waterlogging crops hard to distinguish from water deficit stress with remote sensing, as responses such stomatal closure and leaf wilting occur both situations. Currently, source not considered sensing-based evaporation algorithms this may therefore lead erroneous interpretation for irrigation scheduling. Monitoring can improve models assist management. In addition, frequent spatial information will provide agriculturalists land trafficability, drainage design, choice. This article provides scientific perspective the topic by consulting literature disciplines agronomy, hydrology, sensing. We find solution monitor lies multi-sensor approach. Future routes should focus monitoring combining sensing ancillary data. Here, parameters deduced high resolution Digital Elevation Models (DEMs) play crucial role. proposed approaches prevent agriculture.
