Common Access Resources - Australian Abalone

Common Access Resources are non-excludable and rivalrous in nature. A very common example of common access resources is fish. Because everyone has access to fish and everyone has the right to fish for free, a problem of over exploitation occurs. This is when a resources is consumed beyond the maximum sustainable yield, which implies that the rate of extraction does not allow for the resource to replenish in stock (Common Access Resources & Sustainability).

Australia was facing a problem with over fishing of Abalone. Since abalone is a common access resource, it became prone to over-exploitation. After recognizing this trend of unsustainable yields, the government decided to solve the problem by implementing various regulations that aim to reduce and limit the amount of abalone fishing that takes place in Australia. Examples of these solutions include limiting the regions in which abalone fishing is permitted, placing bag limits on the number of abalones that can be fished, establishing a minimum size requirement, and implementing a licensing system to limit the number of legal abalone fishers (Abalone Recreational Fishing).



However these regulations' effectiveness is debatable. Placing these restrictions has given birth to an illegal abalone market. The market primarily exists due to the limit placed on the number of abalone diving licenses (Tailby and Gant).

Common access resources are goods that are available to all and have substitutes, it is because of their non-restrictive availability, that  over-exploitation of the resource may occur. Fishing is a classic example of CARs in which the maximum sustainable yield is often exceeded. This is evident in the abalone species in Australia. Although the Autralian government has established regulations to prevent unsustainable fishing, the regulations have led to the creation of the "black market".

Excellent work,
I appreciate the amount of effort you put in this post.

To an what extent we can use the same solution in fishing lakes in India.
