Resources and Development - Long Answer Questions
Resources and Development: Conservation of Resources, Small is Beautiful, Brundtland Commission Report (1987), and Our Common Future
Medium (Application & Explanation)
1. Explain the meaning of conservation of resources and show how it supports sustainable development.
Answer:
- Conservation means the judicious use, management, and protection of natural resources.
- It accepts that many resources are limited and can get depleted.
- It reduces environmental degradation like deforestation, soil erosion, and pollution.
- It ensures fair use where resources are unequally distributed.
- It helps balance economic growth with ecological stability.
- It meets present needs without harming the future.
- Thus, conservation is the base of sustainable development.
2. Suggest practical ways to apply the 3Rs (Reduce, Reuse, Recycle) at home and in school. Explain how they conserve resources.
Answer:
- Reduce: Use less electricity and water. Avoid single-use plastics.
- Reuse: Carry a steel bottle. Use cloth bags. Repair and reuse notebooks.
- Recycle: Segregate dry and wet waste. Send paper, glass, and metal for recycling.
- These actions lower resource extraction and wastage.
- They cut pollution and save energy.
- They slow down depletion of non-renewable resources.
- They build habits that support sustainability every day.
3. “Small is Beautiful” promotes small-scale and eco-friendly development. Explain its key ideas and link them to conservation.
Answer:
- It supports small-scale industries and local economies.
- It promotes appropriate technology that is simple and less polluting.
- It values human-centered growth over only output and profits.
- It reduces wastage and encourages efficient resource use.
- It fits local needs and uses local skills.
- It lowers pressure on natural resources and ecosystems.
- So, it directly supports resource conservation and sustainability.
4. What are the main ideas of the Brundtland Commission (1987)? How do they guide resource use?
Answer:
- It defined sustainable development for the world.
- It said development must meet present needs and protect future needs.
- It showed the interdependence of the economy and the environment.
- It called for international cooperation on global issues.
- It linked poverty with over-exploitation of resources.
- It urged eco-friendly policies in industry, farming, and cities.
- These ideas guide us to use resources wisely and fairly.
5. Describe the key messages of “Our Common Future.” Explain its impact on global action.
Answer:
- It made sustainability a global priority.
- It stressed global cooperation for climate, forests, and pollution.
- It asked us to think of future generations in every decision.
- It pushed renewable energy like solar and wind.
- It influenced the Rio Earth Summit (1992) and Agenda 21.
- It shaped modern climate and conservation policies.
- It turned sustainability into a shared global goal.
High Complexity (Analysis & Scenario-based)

6. A drought-prone village is over-extracting groundwater. Design a conservation plan using the 3Rs, sustainable agriculture, and local energy options.
Answer:
- Reduce water use with drip irrigation and mulching in farms.
- Reuse greywater for gardens and trees.
- Recycle organic waste into compost to improve soil moisture.
- Shift to drought-resistant crops and organic farming practices.
- Start rainwater harvesting and recharge pits in homes and schools.
- Use solar pumps instead of diesel pumps to save fuel.
- Follow the Small is Beautiful approach: local skills, low-cost tech, community action.
7. A district must choose between a large coal power plant and many small solar microgrids. Analyze this choice using sustainable development.
Answer:
- A coal plant gives big power output, but causes pollution and emissions.
- Solar microgrids are clean, decentralized, and scalable.
- Coal locks the district into non-renewable resource use.
- Solar builds local jobs, skills, and resilience.
- The Brundtland view favors growth that does not harm the environment.
- “Small is Beautiful” supports appropriate technology for local needs.
- Thus, many solar microgrids better meet sustainability and equity goals.
8. Poor households in a forest fringe area cut trees for fuel. Using the Brundtland approach, suggest a plan that protects both people and nature.
Answer:
- Link poverty alleviation with resource protection.
- Provide clean cooking options like LPG or biogas to reduce tree cutting.
- Create afforestation drives with fast-growing fuelwood species.
- Offer jobs in nursery raising, eco-tourism, and forest management.
- Form self-help groups for microcredit and small enterprises.
- Use Environmental Protection laws to guide sustainable use.
- Educate on rights and duties to ensure shared benefits and care.
9. Two neighboring countries share a river facing pollution and deforestation in the basin. Propose a cooperative plan guided by “Our Common Future.”
Answer:
- Set up a joint river authority for data sharing and action.
- Agree on pollution limits, monitoring, and penalties.
- Run afforestation and soil conservation in the watershed.
- Share clean technologies and renewable energy solutions.
- Support farmers with sustainable practices to cut runoff.
- Create a disaster plan for floods and droughts.
- This follows global cooperation and shared sustainability goals.
10. Your city faces rising waste, traffic pollution, and shrinking green areas. Draft a sustainable urban plan using ideas from conservation and the Brundtland Report.
Answer:
- Enforce segregation and expand recycling facilities.
- Promote public transport, cycling, and walkways to cut emissions.
- Increase afforestation and protect urban wetlands.
- Shift city services to solar rooftops and energy-efficient systems.
- Run awareness programs on the 3Rs and clean habits.
- Use Environmental Protection Act (1986) to regulate polluters.
- Plan growth that is people-centered, eco-friendly, and future-ready.
