FAQs on Water Management Techniques:Rainwater Harvesting and Drip Irrigation Technique Video Lecture - Class 7 Oxford Science: Chapter Notes, Worksheets & Tests
| 1. What is rainwater harvesting and how does it work? |  |
Ans. Rainwater harvesting is the process of collecting and storing rainwater for reuse before it reaches the ground. This technique involves the installation of systems such as gutters, downspouts, and storage tanks to capture rainwater from roofs and other surfaces. The collected water can be used for irrigation, flushing toilets, and even drinking water after proper treatment.
| 2. What are the benefits of using drip irrigation? | |
Ans. Drip irrigation is a highly efficient method of watering plants that delivers water directly to the roots through a network of tubing and emitters. The benefits include reduced water wastage, minimized evaporation, improved crop yields, and reduced weed growth. This method allows for precise control over water application, which is especially beneficial in areas with limited water resources.
| 3. How can rainwater harvesting contribute to sustainable water management? | |
Ans. Rainwater harvesting contributes to sustainable water management by reducing dependency on groundwater and municipal water supplies. It enhances local water availability, decreases runoff and erosion, and helps recharge aquifers. This practice promotes conservation and can lead to reduced water bills for households and businesses, making it an economically viable option for sustainable living.
| 4. What types of plants are best suited for drip irrigation systems? | |
Ans. Drip irrigation is suitable for a wide range of plants, including vegetables, fruits, flowers, and shrubs. It is particularly beneficial for crops that require consistent moisture levels, such as tomatoes, peppers, and cucumbers. Additionally, drought-resistant plants thrive under drip irrigation as it minimizes water stress and promotes healthy growth.
| 5. How can individuals implement rainwater harvesting in their homes? | |
Ans. Individuals can implement rainwater harvesting by installing a rain barrel or a larger cistern connected to the downspouts of their home. It is important to ensure that the collection system is properly filtered to remove debris and contaminants. Homeowners can also check local regulations regarding rainwater harvesting and consider using the collected water for irrigation, washing cars, or flushing toilets.
