Natural Capital refers to the planet’s stocks of natural assets, encompassing geology, soil, air, water, and all living organisms. This concept recognizes that ecosystems provide essential services that benefit humanity and the economy.
Historical Context
The term “Natural Capital” gained prominence in the late 20th century, driven by growing recognition of the role of the natural environment in economic activity. Environmental economists like Robert Costanza and organizations such as the United Nations Environment Programme (UNEP) have advocated for its inclusion in policy and business strategy.
Types/Categories
Natural Capital can be categorized into three main types:
-
- Examples: Forests, fish stocks, freshwater
- Characteristics: Can regenerate over time if managed sustainably.
-
Non-renewable Resources:
- Examples: Fossil fuels, minerals
- Characteristics: Finite resources that diminish with use.
-
- Examples: Pollination of crops by bees, water purification by wetlands
- Characteristics: Processes and conditions provided by ecosystems that benefit humans.
Key Events
- 1987: The Brundtland Report highlighted the importance of sustainability, influencing the concept of Natural Capital.
- 2005: The Millennium Ecosystem Assessment provided a framework for understanding ecosystem services.
- 2012: The Natural Capital Declaration, initiated by financial institutions, aimed at integrating Natural Capital considerations into financial products and services.
Detailed Explanations
Natural Capital Accounting
Natural Capital accounting is a system that integrates Natural Capital into traditional accounting frameworks, providing a fuller picture of economic progress by considering environmental impacts.
Mathematical Models
Natural Capital Valuation Models
Several models exist to value Natural Capital, including:
- Cost-Benefit Analysis (CBA): Weighs the total expected costs versus the benefits of conservation or development projects.
- Hedonic Pricing Method: Estimates economic values for ecosystem services affecting market prices.
- Travel Cost Method: Used for valuing recreational sites by estimating the travel expenses incurred by visitors.

Importance and Applicability
Understanding and managing Natural Capital is crucial for sustainability. It helps governments and businesses make informed decisions that balance economic growth with environmental protection. For example, calculating the economic value of clean water can lead to investments in water conservation practices.
Examples
- Forest Conservation: Preserving forests to maintain biodiversity and carbon sequestration.
- Wetland Restoration: Rehabilitating wetlands to enhance flood control and water purification.
Considerations
- Trade-offs: Balancing short-term economic gains with long-term environmental sustainability.
- Data Limitations: Accurate valuation requires comprehensive environmental data.
Related Terms
- Ecosystem Services: Benefits humans derive from ecosystems.
- Sustainable Development: Development that meets present needs without compromising future generations.
- Biodiversity: The variety of life in the world or in a particular habitat.
Comparisons
- Natural Capital vs. Human Capital: Natural Capital pertains to the environment, while Human Capital involves the skills and abilities of people.
- Natural Capital vs. Manufactured Capital: Natural Capital is derived from natural resources; Manufactured Capital includes buildings and machines created by humans.
Interesting Facts
- The global value of ecosystem services has been estimated at trillions of dollars per year.
- Bees provide over $15 billion worth of pollination services annually in the United States.
Inspirational Stories
The Costa Rican Example: Costa Rica has invested in Natural Capital by paying landowners to conserve forests, which has doubled the country’s forest cover over the past 30 years and boosted eco-tourism.
