Dam Construction Displacement, Jatrya Bhai's Story, Village Harmony vs Urban Slum Struggles | CBSE Session 2026–27
Core Pedagogical Competencies & Concepts
- Jatrya Bhai lived happily in Khedi village surrounded by lush green forests and the river, where community members shared farm work, songs, and food.
- A large river dam was constructed, submerging Khedi village and forcing residents to leave their ancestral land.
- Relocation struggles in Sinduri village: infertile rocky land, costly medical care, lack of schooling, and mockery from local residents.
- Life in Mumbai slums: cramped, expensive tin-roof rooms, dirty gutters, daily wage exploitation, and loneliness.

Q1
Textbook Exercise
Describe the harmonious community life of Khedi village before the dam was built. How did villagers support one another?
[3 Marks]
✅ Step-by-Step Solution & Working
In Khedi village, people lived in peaceful harmony with nature:
- Children learned together to dance, sing, play flute, make clay pots, and recognize birds and medicinal forest herbs.
- Villagers worked together as one big family: during harvests or weddings, everyone pitched in, and elders resolved disputes lovingly without police or courts.

Q2
Textbook Exercise
What are the advantages and disadvantages of constructing large river dams for development?
[4 Marks]
✅ Step-by-Step Solution & Working
Advantages of Dams:
- Generates clean, renewable hydroelectric power.
- Provides irrigation canals to supply water to drought-prone farms.
- Helps control seasonal river flooding and supplies drinking water to distant cities.
- Massive submergence of fertile agricultural lands and ancient forest ecosystems.
- Forced displacement of indigenous villagers who lose their homes, livelihood, and community identity without fair compensation.

Q3
Textbook Exercise
Describe the traumatic emotional and physical impact of forced displacement on tribal communities when dams or factories are built.
[4 Marks]
✅ Step-by-Step Solution & Working
Forced displacement shatters the entire social, economic, and cultural fabric of tribal families:
- Loss of Ancestral Heritage: Villagers leave behind sacred riverbanks, cremation grounds of ancestors, and ancient forests where their families lived for generations.
- Economic Ruin: Independent farmers become landless casual day-labourers in cities, struggling to pay for water, electricity, food, and rent.
- Cultural Alienation: Folk songs, herbal medicinal knowledge, and community solidarity disappear in crowded urban slums where neighbours do not know or trust each other.

Q4
Textbook Exercise
What fundamental facilities should the government ensure are fully established before relocating displaced families?
[3 Marks]
✅ Step-by-Step Solution & Working
Before any relocation takes place, the government must provide:
- Fertile, irrigable agricultural land equal in productivity to what was submerged.
- Permanent pucca houses equipped with free potable water taps, electricity connections, and sanitation drainage.
- Proper government schools, primary health clinics, and accessible all-weather roads.
- Guaranteed rehabilitation employment or livelihood training for youth.

Q5
Textbook Exercise
Compare the environmental sounds and air quality of Khedi village with the urban slums of Mumbai.
[3 Marks]
✅ Step-by-Step Solution & Working
- Khedi Village: Clean, fresh mountain air smelling of wet earth and pine trees. Sounds of rushing river water, leaves rustling in the breeze, birds singing melodiously, and children laughing.
- Mumbai Slums: Air polluted with vehicular exhaust smoke, foul stench from open drains, burning plastic, and deafening traffic horns, train whistles, and factory sirens.

🌟 NEP 2020 Competency-Based Case Study
Tehri Dam Construction & The Displacement of Khedi Village
Jatrya Bhai's peaceful riverbank village of Khedi was submerged under a massive reservoir created by a hydroelectric dam. Although promised agricultural land and modern schools in Sinduri, the displaced villagers received barren stony plots, expensive electricity bills, and hostility in Mumbai.
Analytical Task: Analyze the ethical, social, and economic consequences of large development projects like dams on indigenous rural populations.
Evaluation & Model Answer:
Consequences of Forced Displacement:
1. Loss of Culture and Identity: Villages like Khedi lived in harmony with rivers and forests for centuries. Uprooting them destroys traditional songs, folk knowledge, and community solidarity.
2. Flawed Rehabilitation Promises: Displaced families are often allotted unfertile rocky land without functioning schools, hospitals, or irrigation, sinking them into immediate poverty.
3. Urban Alienation and Poverty: When forced to migrate to mega-cities like Mumbai, skilled rural farmers become landless labourers living in cramped, unhygienic slums, struggling to afford basic drinking water and electricity.
Policy Imperative:
Development projects must obtain informed consent, provide genuine fertile land compensation, and ensure displaced communities receive direct shares in generated electricity and profits.
Rubric: 2 Marks for loss of community culture + 2 Marks for rehabilitation failures + 1 Mark for equitable policy recommendation = 5 Marks
