Drought resistance refers to the ability of plants, crops, or ecosystems to survive and thrive in conditions with little or no water. This adaptation is crucial in areas where rainfall is scarce or unpredictable. Drought-resistant plants, such as cacti and suculents, have special features like thick leaves or deep roots that help them conserve water and endure long dry periods. Farmers often seek out drought-resistant crops to ensure food security in regions prone to drought. These crops require less water and can still produce yields even when conditions are tough. By using such plants, we can better manage our water resources and support sustainable agriculture.
