The settlements in which almost everyone remains engaged in secondary or tertiary activities are known as urban places.

They are also called cities or towns. As they grow, they encroach the surrounding agricultural areas, natural forests etc.

Reasons for Urbanization

3. Loss of agricultural land of farmers.

4. Low yield in the villages.

5. Fixed income from industries.


6. Lack of supporting infrastructure in rural areas.

7. Better education in the cities.

Harmful Impacts of Urbanization

2. Water supply and drainage system should be improved.

3. Waste water treatment plants and efficient public transportation system should be introduced.

4. Rural development should be done.
