Environment & Ecology MCQs

The Indus, Ganga, and Brahmaputra rivers are all major transboundary rivers originating in or significantly fed by the Himalayan glaciers. The Godavari River, however, originates in the Western Ghats of India.

Himalayan glaciers are a crucial source of water for major river systems in Asia. Their accelerated melt threatens long-term water security for millions who depend on these rivers for drinking water, irrigation, and hydropower.

CREM directly contributes to India's efforts in climate change adaptation by strengthening coastal ecosystems against extreme weather events and supports biodiversity conservation by protecting critical marine habitats.

CREM focuses on ecosystem restoration, which includes activities like mangrove plantation, coral reef conservation, and protection of other critical coastal habitats to build natural resilience.

The Coastal Resilience & Ecosystem Restoration Mission (CREM) aims to strengthen coastal defense mechanisms and restore degraded marine and coastal ecosystems, such as mangroves and coral reefs, to enhance resilience against climate change impacts.

The International Solar Alliance (ISA) was jointly launched by India and France during the COP21 climate summit in Paris in 2015.

Rajasthan has the highest installed solar power capacity in India, making it a leading state in solar energy generation.

India has committed to achieving 500 GW of non-fossil energy capacity by 2030 as part of its enhanced Nationally Determined Contributions (NDCs).

The concept of biodiversity hotspots was first introduced by British environmentalist Norman Myers in 1988.

India has four recognized biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-Burma Region, and Sundaland (which includes the Nicobar Islands). The Thar Desert is not a biodiversity hotspot.
