FAQs on NCERT Solutions For Class 10 Science Chapter 16 Management Of Natural Resources in Hindi - 2025-26
1. According to the NCERT solutions for Class 10 Science Chapter 16, what are the four main stakeholders in the management of forests?
The NCERT solutions for Class 10 Science Chapter 16 identify four primary stakeholders for forests:
- Local People: Individuals who live in or around forests and depend on forest products for their livelihood, such as for fodder, firewood, and food.
- The Forest Department: The government body that owns the land and controls the resources from forests, managing them as per official policies.
- Industrialists: Those who use various forest products as raw materials for their factories, such as wood for furniture or leaves for beedi production.
- Wildlife and Nature Enthusiasts: Conservationists who aim to protect and preserve forests and wildlife in their pristine, natural state without exploitation.
2. What practical steps does the NCERT solution suggest an individual can take to help manage (a) water resources and (b) coal and petroleum?
As per the NCERT solutions for the 2025-26 syllabus, an individual can contribute to managing natural resources in the following ways:
- For Water Resources: Avoid wasting water by repairing leaky taps immediately, using a bucket and mug for bathing instead of a shower, and implementing rainwater harvesting systems where possible.
- For Coal and Petroleum: Conserve electricity by switching off lights and fans when not in use (as electricity is often generated from coal). For petroleum, use public transport, carpool, or walk/cycle for short distances, and switch off vehicle engines at traffic signals.
3. How can you make your home more environmentally friendly, based on the principles in Chapter 16?
To make your home more environmentally friendly, the NCERT solutions advise following the principle of the 3Rs (Reduce, Reuse, Recycle). Specific actions include:
- Reduce: Minimise the use of electricity and water. Switch off appliances from the main switch when not in use.
- Reuse: Reuse plastic containers for storage, use old clothes as cleaning rags, and reuse envelopes.
- Recycle: Segregate waste into biodegradable and non-biodegradable categories so that materials like paper, glass, and metal can be properly recycled.
- Conserve Water: Ensure there are no leaking taps in the house.
4. Why is 'Reduce' considered the most effective strategy among the 3Rs (Reduce, Reuse, Recycle) for conserving natural resources?
'Reduce' is considered the most effective strategy because it tackles the problem at its source. When we reduce consumption, we decrease the demand for new resources, saving the energy and materials needed for production and transportation. While 'Reuse' is also effective, it only delays the eventual disposal of an item. 'Recycle' is the third-best option because, although it saves resources, the recycling process itself consumes a significant amount of energy and can create pollution.
5. How does the involvement of local people in forest management lead to more sustainable outcomes compared to purely governmental control?
Involving local people leads to more sustainable forest management because they have a direct, long-term stake in the health of the forest for their livelihood. They possess valuable traditional knowledge about the local ecosystem that can be more effective than generic government policies. When local communities are empowered to manage and benefit from forest resources, they are more motivated to prevent illegal logging and over-exploitation, ensuring the resource is available for future generations. This community-centric approach often balances conservation with sustainable use more effectively than a top-down, purely regulatory approach.
6. The NCERT chapter discusses both large dams and local water harvesting systems. What are the key differences in their environmental and social impact?
Large dams and local water harvesting systems have significantly different impacts:
- Large Dams: These projects often cause major environmental problems like deforestation, loss of biodiversity, and disruption of river ecosystems. Socially, they can lead to the displacement of large numbers of people, creating conflicts over rehabilitation and compensation.
- Local Water Harvesting Systems: Methods like 'Kulhs' in Himachal Pradesh or 'Khadins' in Rajasthan are decentralised, low-cost, and managed by the local community. They have a minimal environmental footprint, help recharge groundwater, and ensure equitable water distribution without causing social displacement. They represent a more ecologically and socially sustainable solution.
7. Why is it often difficult to balance the interests of the four different stakeholders when making decisions about forest management?
Balancing the interests of all four forest stakeholders is challenging due to their conflicting goals. Industrialists often prioritise maximum resource extraction for profit, which can conflict with the long-term sustainability goals of local people who depend on the forest for survival. The Forest Department may focus on revenue generation and strict conservation rules, which can restrict access for both locals and industries. Meanwhile, nature enthusiasts advocate for preserving the forest in its pristine state, which can oppose any form of resource use. Finding a solution that satisfies these competing economic, social, and conservationist interests is the central challenge of sustainable forest management.
