Economic Geography of Assam and North-East India
This domain applies economic geography to Assam and the North-East. Questions test the region’s resource base, industrial pattern, connectivity, border trade and development constraints, with tea, oil, agriculture and Act East policy as recurring themes.
Core rules and concepts
- Assam’s economy is agrarian, with rice, tea, jute and horticulture; tea is a major plantation and export crop.
- Petroleum and coal occur in eastern Assam; refineries at Digboi, Numaligarh and Bongaigaon anchor the industrial base.
- The North-East is landlocked, hill-dominated and connected by narrow corridors, raising transport costs.
- Act East policy and border trade with Bangladesh, Bhutan and Myanmar aim to convert peripherality into connectivity.
- Floods, riverbank erosion, small local markets and fragile infrastructure constrain investment.
Worked example
Why did tea concentrate in Assam? Reasoning: tropical monsoon rainfall, well-drained loam, warm humid conditions, available labour and colonial-era transport links to Kolkata created a comparative advantage. Tea processing is weight-losing, so factories stayed near gardens. The result is a plantation belt in the Brahmaputra valley, especially around Dibrugarh, Sivasagar, Golaghat and Sonitpur.
Traps that cost marks
- Treating the whole North-East as one uniform economy; hill and plain regions differ sharply.
- Ignoring physiography and flood risk when explaining industrial location.
- Confusing state-level and regional data.
- Assuming border trade automatically brings development without roads, customs and market demand.
Use a chain: resource base → locational advantage → transport and policy → market access → development outcome. This structure earns more than a list of industries.
