7. Human Settlements

(a) Availability of water is a major factor affecting settlements.

• Water is the most basic necessity for human survival, agriculture, and daily activities.
• Since ancient times, human settlements in India have flourished in river basins and areas with abundant water supply, leading to nucleated (concentrated) settlements in fertile plains and valleys (like the Narmada Valley or Ganga basin).
• Conversely, areas suffering from extreme droughts or water scarcity, such as the north-east Highlands of Brazil or dry desert areas in India, make agriculture difficult and support only sparse or dispersed settlements.

(b) In Brazil, majority of population is found in the eastern coastal areas.

• The early European settlers formed their settlements mainly in the coastal areas.
• Although the coastal climate is hot and humid, the region benefits from a good water supply, extensive areas under rich soil (ideal for growing coffee), and a large range of natural minerals like iron ore.
• Furthermore, the South Eastern area has a well-developed transport system and a steady energy supply, making regions like Sao Paulo major nucleated and industrialized metropolitan areas.

(c) Urbanization is increasing rapidly in India.

• While the overall level of urbanization in India (31.16% in 2011) is quite low compared to developed countries, the absolute urban population is increasing steadily.
• The expansion of existing urban centres and the emergence of new towns, driven by industrialization and the search for better amenities and employment, have played a significant role in this growth.
• States like Goa, Delhi, Tamil Nadu, Maharashtra, and Gujarat show higher levels of urbanization due to better economic opportunities and infrastructure development.

(d) Settlements are sparse in north-eastern Brazil.

• The rural areas of the north-east Highlands of Brazil suffer from extreme droughts.
• This severe lack of water makes it very difficult to practice agriculture or sustain large populations.
• Consequently, the harsh climatic conditions lead to the formation of only sparse, dispersed settlements in this region.

(e) Except Delhi and Chandigarh, urbanization is low in other parts of India.

• India is predominantly an agrarian country, with a massive population historically settled in fertile river basins and plains practicing agriculture.
• Many states such as Himachal Pradesh, Bihar, Rajasthan, and Odisha still lack extensive industrialization and robust urban infrastructure outside their capital regions, keeping their urbanization levels low (between 0-20% or 21-40%).

(a) Write a comparative note on urbanisation in Brazil and India.

(b) Differentiate between the human settlements in Ganga river basin and the Amazon river basin.

(c) Why do human settlements grow in specific locations only?

• Favorable Physiography and Climate: Flat, plain land and suitable climatic conditions encourage human habitation. Harsh climates or rugged, hilly topography lead to dispersed settlements.
• Availability of Water: Settlements naturally concentrate around river basins and areas with a reliable water supply, which is essential for survival and agriculture.
• Agriculture and Natural Resources: Areas with fertile soil (like the Narmada Valley or Sao Paulo's coffee-growing regions) or abundant mineral resources attract large, nucleated settlements.
• Transport and Infrastructure: Regions with good transport networks, energy supply, and industrial development support dense, urbanized populations.
