The National Biodiversity Action Plan aims to conserve and sustainably use biodiversity, and ensure equitable sharing of benefits arising from its use, aligning with global conservation goals.

Glacial retreat occurs when the rate of melting exceeds the rate of snow accumulation, causing the glacier's terminus to move back.

Himalayan glaciers are the source of major perennial rivers. Their retreat threatens the long-term water supply for millions of people downstream.

Rising global temperatures due to climate change are causing glaciers to melt at an accelerated rate, threatening water security.

West Bengal has the largest mangrove cover in India, primarily due to the Sundarbans, which is the largest mangrove forest in the world.

Mangroves are halophytes, meaning they are adapted to grow in saline or brackish water found in intertidal coastal zones.

The initiative focuses on the restoration and conservation of mangrove ecosystems, which act as natural barriers against cyclones and support biodiversity.

The digital portal facilitates the registration and monitoring of EPR targets for all stakeholders involved in e-waste management.

The rules cover the entire value chain including manufacturers, producers, refurbishers, dismantlers, and recyclers.

EPR mandates that producers are responsible for the environmentally sound management of their products at the end of their life.
