Drip irrigation is the farming method used to grow crops in regions with scarce water resources.

This efficient irrigation technique delivers water directly to the roots of plants through a network of tubes, pipes, and emitters, minimizing water wastage. Drip irrigation is particularly useful in arid and semi-arid regions where water is limited. By targeting the root zone, it reduces evaporation and runoff, ensuring that plants receive the water they need for optimal growth while conserving valuable resources. This method is widely used in regions like California and parts of the Middle East to improve water use efficiency in agriculture.
