Background

Overview

UPSC frequently examines the economic valuation of natural resources, ecosystem services, blue carbon initiatives, and the integration of environmental considerations into economic planning (e.g., Green GDP, Natural Capital Accounting). Mangroves are a critical and vulnerable ecosystem in India, making their valuation and conservation highly relevant.

Mangrove ecosystems provide a wide range of provisioning, regulating, supporting, and cultural services crucial for ecological sustainability and human well-being. Ecosystem Services Valuation (ESV) is a method to quantify the economic benefits of these services, many of which are non-market in nature and often undervalued in conventional development planning.

Facts & tables

Key facts

Diverse Ecosystem Services

Mangroves offer provisioning (fisheries), regulating (coastal protection, climate regulation), supporting (nutrient cycling), and cultural (recreation) services.

Total Economic Value (TEV)

The Pichavaram mangrove ecosystem's TEV was estimated at ₹2,485.38 crore, reflecting its significant ecological and economic contributions.

Blue Carbon Sinks

Mangroves are critical 'blue carbon' sinks, storing substantial carbon in both vegetation and, more significantly, in their sediments.

Policy Integration

ESV helps integrate these non-market benefits into development planning, climate finance mechanisms, and broader conservation strategies.
