CBSE Class 10 Science Chapter 16: Management of Natural Resources NCERT Solutions

1. Waste Segregation: Separate household waste into categories like recyclable (paper, plastic, glass, metal) and non-recyclable (biodegradable waste, sanitary waste). This facilitates proper disposal and recycling.

2. Judicious Use of Resources: Conserve water by fixing leaks, taking shorter showers, and reusing water where possible. Similarly, save electricity by switching off lights and fans when not in use, and unplugging devices.

3. Food Waste Reduction: Plan meals to avoid over-buying and cook only what is needed to minimize food wastage.

4. Reuse and Repurpose: Find new uses for old items. For example, old newspapers can be used for crafts or packing, and plastic containers can be reused.

5. Natural Ventilation: Maximize the use of natural light and airflow by keeping windows open, reducing the need for artificial lighting and fans.

6. Adopt the 3 R's: Consistently follow the principles of Reduce (minimize consumption), Recycle (process waste), and Reuse (use items multiple times).

1. Green Spaces: Plant trees along the boundary walls and cultivate shrubs and small plants around internal roads and the playground. This improves air quality and aesthetics.

2. Water Conservation: Implement a rooftop rainwater harvesting system to collect rainwater. This harvested water can be used for watering plants and other non-potable purposes.

3. Awareness Programs: Organize regular awareness campaigns for students, such as poster exhibitions, seminars, and workshops, on environmental conservation topics.

4. Resource Management: Avoid wastage of water and paper. Encourage students to recycle paper for creative activities like making handicrafts.

5. Energy Efficiency: Promote the use of energy-efficient lighting and appliances, and encourage turning off lights and fans when classrooms are empty.

1. The people who live in or around forests and depend on forest products.
2. The forest department, which owns the land and controls forest resources.
3. The wildlife and nature enthusiasts who want to conserve nature in its original form.
4. Industrialists who use forest produce.

Ideally, the local people who live in or around the forests should have a significant say in deciding the management of forest produce. This is because they often rely directly on forest resources for their livelihood and have a vested interest in ensuring the long-term sustainability of these resources. They tend to take only what they need and often have traditional knowledge about replenishing these resources. While the forest department has legal authority and the conservationists have ecological expertise, involving local communities ensures that management practices are practical, equitable, and sustainable in the long run.

(a) Forests and Wildlife:

• Participate in community initiatives like tree plantation drives and forest conservation programs.
• As a tourist, strictly follow conservation principles, avoid littering, and do not disturb wildlife or their habitats.
• Support organizations actively involved in conserving forests and wildlife through donations or volunteering.
• Educate myself and others about the importance of biodiversity and conservation.

(b) Water Resources:

• Practice water conservation at home by fixing leaks, using water-efficient appliances, and avoiding unnecessary water usage.
• Install a rainwater harvesting system to collect and utilize rainwater.
• Avoid polluting water bodies by disposing of waste responsibly.

(c) Coal and Petroleum:

• Conserve electricity by switching off lights, fans, and appliances when not in use.
• Use energy-efficient gadgets and appliances that consume less power.
• Opt for public transportation, carpooling, cycling, or walking instead of using private vehicles whenever possible.
• Reduce overall energy consumption by making conscious choices in daily activities.

1. Save Electricity: Minimize the use of electrical appliances and switch off lights and fans when not needed. Opt for energy-efficient devices.

2. Reduce Food Waste: Plan meals, store food properly, and consume leftovers to prevent wastage of food resources.

3. Conserve Water: Fix leaks, use water-saving fixtures, and be mindful of water usage during daily activities.

4. Efficient Cooking: Use efficient cooking methods and appliances. For instance, using a pressure cooker can save cooking gas compared to open-pan cooking.

5. Embrace the 3 R's: Actively practice the principles of Reduce (consuming less), Reuse (finding multiple uses for items), and Recycle (processing waste materials into new products). This approach significantly lowers the demand for new resources.

6. Sustainable Choices: Make conscious choices, such as using public transport, buying products with minimal packaging, and opting for durable goods over disposable ones.
