Drought stress occurs when plants do not receive enough water to meet their needs. This lack of moisture can lead to wilting, reduced growth, and even death if the condition persists. Plants rely on water for essential processes like photosynthesis and nutrient transport, so insufficient water can severely impact their health. During drought conditions, soil moisture levels drop, making it difficult for plants to absorb the water they require. Climate change, agriculture, and water management practices can influence the severity and frequency of droughts, affecting ecosystems and food production worldwide.
