Water conservation techniques are essential for preserving water resources. **Rainwater harvesting** collects and stores rain for reuse in irrigation or household tasks. **Drip irrigation** efficiently waters plants by delivering water directly to their roots, minimizing waste. **Low-flow fixtures**, such as faucets and showerheads, reduce water usage in homes. Fixing leaks and using **water-efficient appliances** also save water. In agriculture, **crop rotation** and **drought-resistant crops** reduce water demand. **Greywater recycling**, which reuses wastewater from sinks and showers for irrigation, is another effective method. Conservation efforts help sustain water supplies, protect ecosystems, and ensure future availability.
