Scientists have developed crop varieties that can tolerate drought conditions by possessing traits such as deep root systems, efficient water use, and the ability to maintain growth and productivity under limited water availability.

Light soils have lower water retention capacity, making them more susceptible to drought conditions as they cannot retain moisture for extended periods, leading to faster soil drying and increased stress on crops.
Drought poses a significant threat to rain-fed farming areas where irrigation is not available, as crops depend solely on rainfall for moisture and can suffer from stunted growth, reduced yields, or even crop failure during drought conditions.
Droughts occur due to scarcity or irregular distribution of rainfall, leading to prolonged periods of dryness and water scarcity in affected regions.
Irrigation helps mitigate the impact of rainfall variability by providing a reliable water source for crops, ensuring consistent moisture levels throughout the growing season, and reducing the vulnerability of agriculture to the uncertainties of rainfall patterns.
