The economic notion of resource scarcity differs from what scientists consider for physical abundance of resources. For economists, the net value of resources over the course of time is a measure for making judgment for resource scarcity. From an economic point of view, if marginal costs increase as remaining reserves decline, but market price does not increase as fast as the costs, then the net value is declining and it indicates NON growing scarcity. The fact that remaining reserves are declining would indicate geologic scarcity, but unless market price increases fast enough than marginal cost, the resource is not becoming economically scarce.
Indeed from an economic perspective market forces; technology costs, future demands, substitute commodities prices and their availability will determine the level of scarcity for resources rather than geologic and physical availability of resources.
What about environmental quality; fresh water and clean air? What about species face the danger of extinction? Could we apply this commodity-based and private goods notion of economic scarcity to public and environmental goods? Can this notion guarantee the irreversible exploitation of the life-support resources?
Scarcity is an economic fact of life and can be manageable for commodities that flow through organized institutions such as markets. However where the case is about the scarcity of life support resources and human security may another institution should be in play. In the latter case, interchangeability, market price and demand fluctuation are not applicable.
Having the reality of limited capital and human resources and necessity of their optimal allocations, we need a framework to help us to effectively prioritize our environmental objectives. The more non-market the environmental service, the harder it will be to adapt this economic notion of scarcity. It is suited to private commodities that exchanged in markets.
The existing value system cannot appropriately calculate the real value of environmental goods. Furthermore the prevailing and dominated development model for societies cannot accommodate all aspects of human security.
These all may require the development of new economic value system within new global governance, with focus on effective regional cooperation and conservation efforts, to fulfill the human security needs.
