How can the use of technology be beneficial in solving them? ## Short answer Nepal's major immediate issues are deforestation, landslides, air and water pollution, waste mismanagement, and climate impacts. Technology aids via electric vehicles, biogas, GIS monitoring, bio-engineering, and early warning systems, combined with community participation and strong laws. ## Answer Nepal's environment is fragile because of its young mountains, monsoon rain and fast, unplanned development. The major immediate environmental issues and the role of technology in solving them are: #### Major immediate environmental issues for Nepal 1. **Deforestation and forest degradation** – illegal logging, fuelwood use, encroachment and road building. 2. **Soil erosion and landslides** – fragile young mountains, steep slopes, haphazard rural roads cut by bulldozers. 3. **Air pollution** – Kathmandu Valley often has PM2.5 far above WHO limits; sources: vehicles, brick kilns, dust, waste burning, forest fires. 4. **Water pollution** – untreated sewage and industrial waste in rivers (Bagmati, Bishnumati); contaminated drinking water; arsenic in Terai groundwater. 5. **Solid waste management** – open dumping; the Sisdol/Bancharedanda landfill problem in Kathmandu. 6. **Unplanned urbanisation** – loss of open space and farmland, traffic, noise. 7. **Climate change impacts** – glacier melt, GLOF risk, erratic rainfall, floods and droughts, drying springs. 8. **Loss of biodiversity** – poaching, habitat loss, invasive species. 9. **Riverbed mining** – excessive sand and gravel extraction (e.g. Chure region). 10. **Floods and disasters** – Terai floods, landslides, earthquakes. #### How technology can help | Issue | Useful technology | |---|---| | Air pollution | Electric vehicles and e-buses, zig-zag (induced draught) brick kilns, emission testing, air-quality sensors and alerts | | Water pollution | Sewage treatment plants, constructed wetlands, low-cost filters, SODIS, chlorination, arsenic filters | | Solid waste | Waste segregation, composting, biogas, recycling, sanitary landfill, waste-to-energy | | Deforestation | Improved cooking stoves, biogas, LPG/electric cooking, GIS and remote sensing to monitor forests | | Landslides, erosion | Bio-engineering (plants + structures), proper road design, GIS hazard mapping | | Climate change | Hydropower, solar, wind; GLOF early warning and lake lowering (as at Tsho Rolpa and Imja) | | Floods | Flood forecasting, SMS early warning, river training works | | Urbanisation | GIS planning, green buildings, e-governance | | Biodiversity | Camera traps, GPS collars, drones against poaching | | Agriculture | Drip irrigation, organic and integrated pest management | Technology works best when it is **appropriate** (low-cost, locally maintainable), combined with good laws (Environment Protection Act, 2076), public awareness and community participation. Example: Nepal's community forestry with improved stoves and biogas has helped increase forest cover to about 45% of the land area. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. Why is Nepal prone to soil erosion and landslides? A. Flat land and little rain B. Young fragile mountains, steep slopes, monsoon rain and haphazard bulldozer roads C. Too many forests D. Desert climate Answer: B. Fragile young mountains and unplanned roads cause erosion and landslides. (Key point: Landslides) 2. Which technology reduces air pollution from brick kilns and vehicles? A. Open dumping B. Zig-zag kilns and electric vehicles C. Bulldozer roads D. Riverbed mining Answer: B. Zig-zag kilns and EVs reduce emissions. (Key point: Air pollution) 3. Which technology helps monitor forests and hazards? A. GIS and remote sensing B. Fuelwood stoves C. Landfills D. Chlorination Answer: A. GIS and remote sensing map forests and hazards. (Key point: Monitoring) 4. What makes technology effective in Nepal? A. High cost and complex B. Appropriate (low-cost, locally maintainable) with laws, awareness and community participation C. Imported only D. Ignoring laws Answer: B. Appropriate tech with laws and community participation works best, e.g. community forestry with stoves and biogas. (Key point: Appropriate technology) ## Related in Technology, Environment and Society - [Short note: Major global environmental issues](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Aglobal-env-issues-note) — Technology, Environment and Society, chapter 4 - [Nepal's environmental issues and global effort](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Anepal-env-issues-global-effort) — Technology, Environment and Society, chapter 4 - [Nepal's environmental issues and mitigation strategies](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Anepal-env-issues-strategies) — Technology, Environment and Society, chapter 4 - [Current environmental issues: Nepal vs global](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Anepal-vs-global-env-issues) — Technology, Environment and Society, chapter 4 - [Short note: Major environment issues of Nepal](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Anepal-env-issues-note) — Technology, Environment and Society, chapter 4 - [Global and national environmental issues](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Aglobal-and-nepal-env-issues) — Technology, Environment and Society, chapter 4, asked 2× ## Related in other subjects - [EIA; environmental problems in Nepal](https://www.bctengineer.com/question.md?key=semester_7%2Fproject_engineering%3Aeia-nepal-problems-improve) — Project Engineering, chapter 2 - [VoIP and IPI issues in Nepal](https://www.bctengineer.com/question.md?key=semester_8%2Finternet_and_intranet%3Avoip-ipi-issues-nepal) — Internet and Intranet, chapter 7 - [Major discontinuity systems of Nepal Himalaya](https://www.bctengineer.com/question.md?key=semester_4%2Fengineering_geology_ii%3Anepal-discontinuity-systems) — Engineering Geology II, chapter 2, asked 12× - [Appropriate technology for Nepal transport](https://www.bctengineer.com/question.md?key=semester_7%2Fenergy_environment_and_society%3Aappropriate-technology-nepal-transport) — Energy Environment and Society, chapter 1
