Sustainable development and climate change are high-yield because they connect policy, environment, economy and technology. For Computer Engineer candidates, link this topic with data systems, early warning, GIS, energy efficiency and resilient infrastructure.
Core Definitions
Sustainable development
Standard definition: Development that meets present needs without compromising future generations’ ability to meet their needs.
Exam meaning: आजको विकासले भविष्यको पुस्ताको आवश्यकता पूरा गर्ने क्षमता नबिगार्ने विकास।
Climate change
Standard definition: Long-term change in temperature, rainfall and climate patterns, largely intensified by human activities.
Exam meaning: Temperature/rainfall लगायत climate patterns मा दीर्घकालीन परिवर्तन।
Concept Teaching
Sustainability balances economy, society and environment. Climate change increases hazards such as floods, landslides, heat stress and glacial risk. Answers should include mitigation, adaptation and resilience.
Sustainability Pillars
Use three-pillar framework.
| Pillar | Meaning | Example |
|---|---|---|
| Economic | Productive and viable growth | Green jobs |
| Social | Equity and inclusion | Access to services |
| Environmental | Resource conservation | Pollution control |
Climate Response
Separate mitigation and adaptation.
- Mitigation reduces greenhouse gas emissions or increases sinks.
- Adaptation adjusts systems to climate impact.
- Resilience means ability to absorb and recover from shocks.
- Disaster risk reduction reduces exposure and vulnerability.
- Early warning systems use sensors, communication and preparedness.
Maps, Tables and Diagrams To Practice
- Draw sustainability three-pillar diagram.
- Draw climate risk chain: hazard, exposure, vulnerability, risk.
- Map mitigation vs adaptation examples.
- Draw early warning system flow.
High-Yield Facts and Frameworks
- SDGs provide global development goals.
- Climate impacts are linked with disaster risk and livelihood.
- Technology supports monitoring, forecasting and resilient service delivery.
| Concept | Meaning | Example |
|---|---|---|
| Mitigation | Reduce climate cause | Renewable energy |
| Adaptation | Adjust to impact | Flood-resilient infrastructure |
| Resilience | Recover from shock | Backup systems |
| EIA | Assess project impact | Hydropower/road review |
Exam Point
- Do not mix mitigation and adaptation.
- Mention SDGs in sustainability answers.
- For Nepal, link climate with mountains, floods, landslides and agriculture.
- Add ICT/GIS/early warning for technical relevance.
Worked Example
For climate-resilient ICT infrastructure, mention site selection, backup power, redundant links, flood-safe data centers, disaster recovery plan and early warning integration.
Answer Pattern
- Define sustainable development.
- Explain environment/climate challenge.
- Differentiate mitigation/adaptation.
- Discuss Nepal impacts.
- Add technology and governance solutions.
Common Mistakes
- Writing only pollution control.
- Confusing weather and climate.
- Mixing mitigation/adaptation.
- No local Nepal context.

Final Summary
- Sustainable development balances economic, social and environmental goals.
- Climate change increases risk and uncertainty.
- Mitigation and adaptation are different responses.
- Technology supports monitoring and resilience.
