4.2 Agriculture
The agriculture sector was responsible for significant water loss over 16 years. Factors such as poor irrigation systems, evaporation, and overall inadequate water management could be the reasons for this waste of water resources. Table \ref{743307} summarizes the lands under different irrigation systems in hectares, including sprinkler, drip, and pressurized, in 2019, in two agricultural areas in the Eskandari watershed \cite{iran2019a}. More than 86% of cultivated lands were under sprinkler irrigation, 23100 hectares. For this reason, we investigated the potential decrease in irrigation efficiency in the region, primarily caused by the adoption of sprinkler irrigation. This type of irrigation method increases water loss through evaporation and wind drift (WDEL) \cite{Play_n_2005}, resulting in the depletion of valuable water resources from the watershed. In many situations, Wind Drift and Evaporation Losses (WDEL, %) can be larger than the other types of water losses, such as runoff and deep percolation \citep*{A_S_Dylla_1983}. As a result, we evaluated and estimated wind drift and evaporation losses in sprinkler irrigation and compared them with the calculated volume of lost water (336.14 MCM).
