It pays to use water wisely

In the tropics, especially in semi-arid regions, most vegetable production occurs in the dry season, meaning that virtually all the water needed must come from irrigation. Even during the rainy season, dry spells may be common and supplemental watering necessary.

Although water is usually in short supply during the dry season, it's often used inefficiently. This not only wastes water, but lowers crop yields and quality.
