Conceptual Approaches to Natural Resource Management

1. Natural resource management ties in with applied concepts such as maximum sustainable yield (MSY) and optimum utilization. Every natural resource has its optimum utilization, or acceptable levels of use, which are established scientifically and according to which management authorities regulate its exploitation. Such a concept presupposes scientific knowledge as a basis for management and also a regulatory authority (whether national or international) capable of enforcing the exploitation of the resources in accord with such scientific knowledge.

2. The MSY is a regulatory concept that translates laws of population dynamics into a management tool. Population studies have shown that, in a given population, when the deaths increase as a result of harvesting (exploitation), reproduction rates start to rise (as if compensating for the deaths). That resultant surplus production can be harvested sustainably, provided that the harvest is consistently maintained under the MSY, which is specific to each population(rather than to the species as a whole). That is the peak level, beyond which the surplus production starts to decline because the negative effect of decreasing numbers on the overall population starts to exceed the positive effect of increased reproduction rates. Subsequently, the population as a whole (and not just the harvestable surplus) begins to decline. On the other hand, maintaining exploitation levels below the MSY creates an efficient use of the resources’ regenerative capacities, thus in principle enabling exploitation to continue indefinitely.

3. Another way to think about natural resource management is to think about the purpose of the management. The management objectives are determined by the purpose of the resource itself—as a primary resource, as a raw material or fuel, as a source of food, or as a recreational resource.
