Blue Economy: Harnessing Ocean Resources Sustainably

Oceans cover roughly 70% of the Earth's surface and are crucial to food security, energy production and international trade, making the sustainable management of ocean resources — the "blue economy" — an increasingly important policy priority for coastal nations, including India.

India's key initiatives in this space include the Sagarmala Project, which focuses on port-led industrialisation and the development of associated logistics infrastructure along the coastline; the Deep Ocean Mission, which concentrates on ocean exploration, mineral resource assessment and marine biodiversity conservation in India's exclusive economic zone and beyond; and India's active participation in the Indian Ocean Rim Association, which promotes regional cooperation on maritime security, trade facilitation and environmental protection among member states bordering the Indian Ocean.

Significant challenges threaten the sustainability of ocean resources, including overfishing and marine pollution, both of which directly threaten marine biodiversity and the livelihoods of coastal communities that depend on fishing; climate change, which is driving rising sea levels and ocean acidification with cascading effects on marine ecosystems; and illegal exploitation, including unsustainable and often unregulated extraction of marine resources that undermines long-term conservation efforts.

The way forward requires sustainable exploitation practices, including responsible fishing quotas and more careful resource management overall; active marine biodiversity conservation through the establishment and effective enforcement of marine protected areas; and strengthened maritime security, achieved by building up naval and coast guard capabilities to protect both ecological assets and economic interests in India's maritime zones. For Mains, this theme connects naturally to sustainable development, coastal state economics and India's broader maritime strategy in the Indian Ocean region. In short, the blue economy theme rewards answers that connect ecological sustainability directly to economic opportunity rather than treating them as competing priorities, since India's Sagarmala and Deep Ocean Mission initiatives are explicitly designed around that same dual logic of growth alongside conservation.
