Answer:
Allocate existing resources more efficiently among competing uses.
Explanation:
The main goal of resource development is to find ways that allocate resources more efificiently, to spread the available resources in a way that maximizes economic and social benefit taking into account the different competing uses.
Resource development does not necessarily promote central planning because it can make use of market strategies to achieve its goal, and it cannot increase the amount of resources available as well, because these are determined by the natural endownment that each area has.
