Resources — UPSC Mains Model Answer

Flow resources such as solar radiation, wind, and river discharge exist as continuous natural flows. They can only be harnessed at the rate they are generated; unused flow is typically lost rather than accumulated. Renewable energy policy in India — including the National Solar Mission — is premised on this characteristic.

Fund resources are those whose total stock is finite but whose rate of use can be regulated — minerals and fossil fuels are classic examples. The question's description partially captures this but conflates it with stock resources. The critical distinction is that fund resources are depleted with use, unlike stock resources which regenerate.

The question assigns to 'stock resources' the definition that actually belongs to renewable or flow resources. In standard resource geography, stock resources refer to finite, non-renewable reserves — coal, petroleum — where extraction permanently reduces availability. Confusing these categories leads to flawed conservation frameworks.

Misclassifying resources distorts extraction policy, environmental impact assessments, and intergenerational equity calculations. India's Forest Conservation Act and Mines and Minerals Act operate on distinct logics precisely because forests (fund/renewable) and minerals (stock) behave differently under exploitation.
