How and where charsa irrigation method is used?

Charsa irrigation is a traditional method primarily used in the arid and semi-arid regions of South Asia, particularly in parts of India and Pakistan. This method involves the construction of small earthen channels or furrows that guide water directly to the root zones of crops. It is often employed in conjunction with rain-fed agriculture to optimize water usage, especially in areas with limited water resources. Charsa irrigation is particularly beneficial for growing crops like wheat, barley, and various pulses, as it enhances moisture retention and minimizes water wastage.
