How was the idea of sustained supply in colonial forest policy double-sided?

Correct answer: It protected long-term timber production but restricted local uses

In colonial forest policy, “sustained supply” sounded like conservation, but its main purpose was to ensure a regular supply of valuable timber for the state, railways, ships, and industries. Forests were managed for long-term commercial production rather than for the varied needs of people who had traditionally used them. Thus, the idea had two sides: it tried to prevent the exhaustion of timber, yet it reduced customary access to fuel, grazing, fruits, leaves, and other forest products.

Option A is correct because it includes both parts of this contradiction. The policy protected future timber production through controlled cutting and plantations, but it also restricted local collection and cultivation. Option B reverses the historical reality, since state control increased. Options C and D are wrong because forests were not left untouched and market demand continued to guide policy.
