Historical Context
The concept of common access resources has been discussed for centuries, notably highlighted in the 1968 article “The Tragedy of the Commons” by ecologist Garrett Hardin. This seminal work brought attention to how individuals, acting in their self-interest, can lead to the depletion of shared resources.
Types/Categories
- Natural Resources: Lakes, forests, fisheries, and grazing lands.
- Man-made Commons: Urban roads, public parks, and public libraries.
- Global Commons: Atmosphere, oceans, and polar ice caps.
Key Events
- 1968: Garrett Hardin’s “The Tragedy of the Commons” publication.
- 1972: The UN Conference on the Human Environment highlighted environmental sustainability.
- 1987: The Brundtland Report emphasized sustainable development.
- 1997: The Kyoto Protocol aimed at reducing greenhouse gas emissions.
Detailed Explanations
Characteristics of Common Access Resources
- Non-excludable: Difficult to prevent others from using the resource.
- Rivalrous: One person’s use reduces availability for others.
- Vulnerable to Overuse: High risk of depletion due to excessive consumption.
The Tragedy of the Commons
The tragedy of the commons occurs when individuals overconsume a shared resource, leading to its degradation. This happens because each person receives the full benefit of their usage while the costs are distributed among all users.

Importance and Applicability
Understanding common access resources is critical for:
- Policy Making: Governments can create regulations to manage these resources sustainably.
- Economic Planning: Economists design mechanisms to prevent overuse.
- Environmental Conservation: Ensuring long-term availability of natural resources.
Examples
- Fisheries: Overfishing can lead to the collapse of fish populations.
- Water Resources: Shared water bodies can suffer from pollution and overuse.
- Air Quality: Air pollution from factories and vehicles can degrade the environment.
Considerations
- Regulatory Policies: Implementing quotas or permits.
- Community Management: Local communities managing resources collectively.
- Technological Solutions: Using technology to monitor and control usage.
Related Terms with Definitions
- Public Good: A good that is non-rivalrous and non-excludable.
- Private Good: A good that is both rivalrous and excludable.
- Externality: A cost or benefit affecting third parties who did not choose to incur that cost or benefit.
Comparisons
- Common Access Resources vs. Public Goods: Public goods are non-rivalrous and non-excludable, while common access resources are non-excludable but rivalrous.
- Common Access Resources vs. Private Goods: Private goods are both excludable and rivalrous, unlike common access resources.
Interesting Facts
- The concept of “commons” dates back to medieval England where villagers shared grazing land.
- Global commons like the ozone layer have seen international cooperation to manage their use.
Inspirational Stories
Elinor Ostrom, who won the Nobel Prize in Economic Sciences in 2009, demonstrated how local communities could effectively manage common resources through collective action.

Summary
Common access resources are essential but susceptible to overuse and depletion due to their non-excludable yet rivalrous nature. Understanding and managing these resources through various approaches is crucial for sustainable development and environmental conservation.
