India faces imbalanced regional development due to uncertainty in the development of states or districts.
The main factors affecting regional development of any region are physical factors like climate, soil, location, relief, geology of the country, forest, etc.
Some regions have favourable relief, climate, fertile soil or favourable geographical location or ample natural resources. Such regions develop faster. For example, the northern plains of India are well developed due to plain relief, fertile soil and moderate climate. Coastal cities like Mumbai, Chennai are well developed due to development of ports and harbours.
Some regions have unfavourable relief or climate. Therefore, development is limited.
For example, the north-eastern states of India have less development due to hilly relief, heavy rainfall, frequent flooding and inaccessibility.
The human factors like market demand, transportation, power supply, banking and insurance facilities, communication facilities, technological development, skilled labour, etc., contributes to the development of a region.
For example, due to unfavourable human factors, the Himalayan region is less developed. Thus, there is regional imbalance in India.
