Natural resources are materials or substances found in nature that are valuable to humans. They include minerals, forests, water, soil, and energy sources. Chhattisgarh, a state in central India, is rich in various natural resources that play a vital role in its economy and environment. These resources support industries like mining, agriculture, power generation, and forestry, making the state an important contributor to India's development.
In this section, we will explore the key natural resources of Chhattisgarh, understand their locations, uses, and economic importance, and learn how they impact the lives of people in the state.
Minerals are naturally occurring substances extracted from the earth. Chhattisgarh is known for its abundant mineral wealth, especially coal, iron ore, bauxite, and limestone. These minerals are essential raw materials for industries such as steel, cement, and power generation.
| Mineral | Estimated Reserves (Million Tonnes) | Key Mining Areas | Annual Production (Million Tonnes) |
|---|---|---|---|
| Coal | 58,000 | Korba, Raigarh, Surguja | 140 |
| Iron Ore | 2,500 | Bastar, Durg, Raipur | 20 |
| Bauxite | 300 | Bastar, Dantewada | 4 |
| Limestone | 1,200 | Durg, Raipur, Bilaspur | 15 |
Coal Reserves: Chhattisgarh holds one of the largest coal reserves in India. Coal is a fossil fuel used mainly for electricity generation and steel production. The Korba and Raigarh districts are the major coal mining centers. Coal is extracted through both open-cast and underground mining methods.
Iron Ore Deposits: Iron ore is the primary raw material for steel manufacturing. Chhattisgarh's iron ore deposits are mainly found in Bastar and Durg regions. Mining here supports the local steel industry and contributes to national production.
Bauxite and Limestone: Bauxite is the ore used to produce aluminium, while limestone is crucial for cement manufacturing. Both minerals are found in significant quantities in the southern and central parts of the state.
Forests are vital natural resources providing timber, fuel, and non-timber products like medicinal plants, fruits, and resins. They also support wildlife and maintain ecological balance.
Chhattisgarh's forests mainly consist of tropical moist deciduous and dry deciduous types. These forests cover about 44% of the state's geographical area, making it one of the most forest-rich states in India. Timber from these forests supports local industries, while non-timber products like tendu leaves are important for rural livelihoods.
The state is also home to diverse wildlife including tigers, leopards, elephants, and various bird species, contributing to its rich biodiversity and ecological importance.
Water is a crucial natural resource for drinking, irrigation, and power generation. Chhattisgarh is blessed with several major rivers and reservoirs that support these needs.

The Mahanadi and Indravati rivers are the main water sources. Large dams like the Hirakud and Dudhawa reservoirs store water to regulate supply. These water bodies support extensive irrigation networks that enable farming even during dry seasons. Additionally, hydroelectric power plants harness river water to generate electricity, contributing to the state's energy needs.
Soil and water together form the basis of agriculture. Chhattisgarh has fertile alluvial and red soils suitable for growing a variety of crops.
The major crops include rice (the staple food), maize, pulses, and oilseeds. Irrigation facilities from rivers and reservoirs enhance crop yields by providing water during dry periods. Traditional and modern farming practices coexist, with increasing use of mechanization and improved seeds.
Energy resources in Chhattisgarh include thermal power plants fueled by coal, hydroelectric power from rivers, and emerging renewable energy projects like solar and biomass.
Thermal power plants are the backbone of electricity generation, using the state's abundant coal reserves. Hydroelectric plants utilize river water flow to produce clean energy. Renewable energy initiatives are gaining momentum to diversify the energy mix and reduce environmental impact.
Step 1: Identify the part and whole for the percentage calculation.
Part = Annual coal extraction = 140 million tonnes
Whole = Total coal reserves = 58,000 million tonnes
Step 2: Use the percentage formula:
\[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 = \left( \frac{140}{58000} \right) \times 100 \]
Step 3: Calculate the value:
\[ \frac{140}{58000} = 0.00241 \]
\[ 0.00241 \times 100 = 0.241\% \]
Answer: Approximately 0.24% of the coal reserves are used annually.
Step 1: Identify the part and whole.
Part = Forest area = 59,400 sq km
Whole = Total area = 135,000 sq km
Step 2: Apply the percentage formula:
\[ \text{Percentage} = \left( \frac{59400}{135000} \right) \times 100 \]
Step 3: Calculate the fraction:
\[ \frac{59400}{135000} = 0.44 \]
\[ 0.44 \times 100 = 44\% \]
Answer: Forest cover in Chhattisgarh is approximately 44% of the total area.
Step 1: Identify total water storage and percentage for irrigation.
Total water = 500 MCM
Percentage for irrigation = 60%
Step 2: Calculate the volume for irrigation:
\[ \text{Irrigation water} = \frac{60}{100} \times 500 = 0.6 \times 500 = 300 \text{ MCM} \]
Answer: 300 million cubic meters of water is available for irrigation.
Step 1: Identify quantity and price per tonne.
Quantity = 20 million tonnes
Price per tonne = Rs.3,000
Step 2: Use the economic value formula:
\[ \text{Value} = \text{Quantity} \times \text{Price per tonne} = 20,000,000 \times 3000 \]
Step 3: Calculate the value:
\[ 20,000,000 \times 3000 = 60,000,000,000 \text{ INR} \]
Answer: The economic value of iron ore produced annually is Rs.60,000 crore.
Step 1: Identify plant capacity and operating hours.
Power = 150 MW
Operating hours = 5,000 hours
Step 2: Use the energy generation formula:
\[ \text{Energy (MWh)} = \text{Power (MW)} \times \text{Operating Hours (h)} = 150 \times 5000 \]
Step 3: Calculate the total energy:
\[ 150 \times 5000 = 750,000 \text{ MWh} \]
Answer: The plant generates 750,000 megawatt-hours of energy annually.
