Subtopic 9.1: Preserving Land Ecosystems & Halting Biodiversity Loss

If it walks on land, the goal number is 15. If it swims, it is 14.

Starting point

SDG 15 is life on land. It covers forests, mountains, drylands and inland biodiversity: protect, restore and promote sustainable use, halt land degradation and biodiversity loss, and combat desertification. The RAS item asks which of the seventeen goals focuses on life on land, and the key is SDG 15.

The neighbours are the trap. SDG 13 is climate action. SDG 14 is life below water. SDG 16 is peace, justice and strong institutions. A forest is not a climate goal merely because trees store carbon, and it is not a marine goal. Land is 15. Climate policy can serve 15 and still be numbered 13 when the question is about climate.

Attach life on land to SDG 15.
Include desertification and biodiversity loss, not only trees.
Keep SDG 13 for climate, SDG 14 for oceans, SDG 16 for institutions.
If the question quotes the UN phrase “terrestrial ecosystems”, it is still 15.
Do not answer with the India Index rank. This question is about the goal’s identity.

Worked example. A project that restores a tiger landscape is SDG 15. A project that cuts coal emissions is primarily SDG 13, even if the forest benefits. A project that restores a coral reef is SDG 14. The RAS wording — protect, restore and promote sustainable use of terrestrial ecosystems — is the SDG 15 formula. Mark 15 even if a climate option looks greener.

Memory hook. 15 land, 14 water-below, 13 climate, 16 peace. Desertification sits inside 15.

Further explanation

Land degradation neutrality, the idea that new degradation is balanced by restoration, is the policy handle inside SDG 15. Biodiversity targets sit here too, and they overlap the Convention on Biological Diversity. The exam does not require the convention’s articles. It requires the goal number and the terrestrial scope.

Trade-offs are real: an afforestation programme that plants a single exotic species can look like a forest gain and a biodiversity loss. A good sentence admits that SDG 15 is not “any green cover”.

SDG 15

Life on land: terrestrial ecosystems, desertification, biodiversity loss.

Not 15

SDG 13 climate, SDG 14 life below water, SDG 16 peace and justice.

Concept

Original notes

Subtopic 9.1: Preserving Land Ecosystems & Halting Biodiversity Loss

Sustainable Development Goal 15 (SDG 15) focuses specifically on \"Life on Land.\"

The official UN mandate for SDG 15 is: \"Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss.\"

It acts as the ecological foundation for terrestrial living systems, covering the conservation of freshwater mountains, drylands, endangered species protection, and sustainable forestry.

Important points

SDG 15 targets terrestrial ecosystems, combatting desertification, and biodiversity loss.
SDG 13 covers Climate Action, SDG 14 covers Marine Life, and SDG 16 covers Peace and Justice.
