Shelter — Houses Across Regions of Odisha and India

Overview

Shelter is one of the three basic human needs along with food and clothing. In the OTET Paper I Environmental Studies section, questions on shelter focus on how houses differ across regions based on climate, locally available materials, occupation, and cultural traditions. This topic connects geography, climate, and human adaptation — a core theme in EVS.

Students must understand why a house in coastal Odisha looks different from one in Rajasthan or the Himalayan region. The examiner typically tests recognition of house types by region, materials used, and the logic behind design choices. Expect 2–4 questions linking shelter to climate, resources, and the lives of people in different parts of India and Odisha specifically.

Key Concepts

• **Shelter as adaptation**: House design is shaped by climate (hot, cold, wet, dry), terrain (plains, hills, coast), available materials (mud, bamboo, stone, wood), and occupation (farming, fishing, herding).

• **Pucca vs Kutcha houses**: Pucca houses use cement, bricks, and concrete; kutcha houses use mud, thatch, bamboo, and leaves. Semi-pucca houses combine both.

• **Roof design and climate**: Sloping roofs in high-rainfall areas (Odisha coast, Kerala, Assam) allow rainwater to drain; flat roofs in dry regions (Rajasthan, parts of Deccan) are used for sleeping and drying grain.

• **Wall thickness and temperature**: Thick mud or stone walls in hot deserts (Rajasthan) keep interiors cool; thin bamboo walls in humid areas (Assam, coastal Odisha) allow air circulation.

• **Elevated houses (stilt houses)**: Built in flood-prone and heavy-rainfall areas (Assam, Meghalaya, parts of coastal Odisha) to protect from water and wild animals.

• **Regional materials**: Bamboo and cane in the Northeast; mud and thatch in rural Odisha; stone in hilly regions; ice blocks for igloos in polar areas.

• **Urban vs rural housing**: Urban areas have multi-storey apartments and planned colonies; rural areas have single-storey houses with open courtyards and cattle sheds.

• **Temporary shelters**: Nomads and certain tribal communities use tents or portable huts that can be moved with their livestock.
