Q.What one of the following is the main reason due to which share of forest has shown an increase in the last forty years?

The share of forest has increased primarily because the government has legally notified more land as forest area over the years. This means that land which was previously not recorded as forest has been brought under the official forest cover, even if the actual tree density on that land has not changed much.

Afforestation efforts, community participation, and community forest lands have all contributed to forest conservation, but they are not the main driver of the recorded increase in forest share. The key factor is the expansion of the notified forest area through legal and administrative measures.

The question asks about a curious fact: India’s recorded forest area has grown in official statistics over the past four decades, yet this does not necessarily mean that more trees are actually standing. To understand why, we need to separate two very different things — recorded forest area (what the government legally classifies as forest) and actual forest cover (the physical presence of trees on the ground).

The increase in the share of forest in official records is primarily a bureaucratic and legal phenomenon. Over the last forty years, state governments have brought more land under the category of “notified forests” — that is, land that is legally declared as forest under the Indian Forest Act or other state laws. This process does not always involve planting a single tree. It often means that land which was already there — perhaps degraded, scrubby, or even barren — is simply reclassified as forest on paper. The result is a statistical jump in forest share without a corresponding ecological improvement.

Why has this happened? One major reason is the push to meet national and international targets for forest cover. Governments have found it easier to expand the notified area than to actually regenerate degraded forests or halt deforestation elsewhere. When a patch of land is notified as forest, it comes under legal protection, which can prevent future encroachment or conversion to agriculture. But the initial “increase” is a legal-administrative act, not a biological one.

Now look at the other options. Afforestation efforts (option a) have certainly happened — through schemes like the National Afforestation Programme and the Green India Mission — but their impact on the share of forest in total land area has been modest. Many plantations fail, and even successful ones take decades to mature. Community forest land (option b) has increased in some states under the Forest Rights Act, but this is a recent and uneven trend, not the main driver of the forty-year rise. Better people’s participation (option d) is a desirable goal and has helped in some regions, but it is not the primary statistical cause of the increase.

So the correct answer is (c) Increase in notified area allocated for forest growth. This reflects a policy choice to bring more land under the legal definition of forest, which then shows up in national statistics as an increase in forest share. It is a reminder that numbers can tell a story, but not always the one we expect.
