🔬研究者:Provides a comprehensive methodology for GEP estimation using SEEA framework, useful for researchers in natural capital accounting and ecosystem services valuation.

🏢実務担当者:Offers insights into how ecosystem services can be valued and potentially integrated into corporate sustainability reporting, especially for nature-related disclosures.

🏛政策担当者:Demonstrates the economic significance of ecosystems, supporting the case for integrating natural capital into national development planning and climate resilience strategies.

Planetary health recognizes that human health, well-being, and sustainable development depend fundamentally on the integrity of natural ecosystems that regulate climate, maintain biodiversity, secure food and water resources, and protect populations from environmental risks. As environmental degradation increasingly threatens this life-support system, there is a growing need for economic indicators that explicitly recognize the value of natural capital alongside conventional measures of development. Gross Ecosystem Product (GEP) has emerged as comprehensive metric for quantifying the monetary value of ecosystem services and informing evidence-based policy. This study estimates India’s GEP for the period 2011–2012 to 2020–2021 using an ecosystem accounting framework aligned with the System of Environmental Economic Accounting (SEEA). The analysis integrates provisioning services (timber, non-timber forest products, fuelwood, and fisheries), regulating services (carbon sequestration), and cultural services (nature-based tourism) using market price, replacement cost, and benefit transfer methods based on secondary data from national and published sources. India’s total GEP is estimated at US$207.05 billion, highlighting the substantial but under-recognized contribution of ecosystems to the national economy and societal well-being. Regulating services dominate GDP, with carbon sequestration alone accounting for US$166.73 billion, followed by provisioning services, while cultural services contribute a relatively smaller share. These findings reveal a significant gap between ecosystem contributions and their representation in conventional metrics such as Gross Domestic Product (GDP), underscoring the limitations of growth-centric development frameworks. By integrating ecosystem values into national accounting, GEP provides a practical tool for advancing planetary health, strengthening climate resilience, conserving biodiversity, supporting ecosystem-based management, and guiding policies that align economic development with ecological sustainability and long-term human well-being.
