Hi Laurent,
It depends upon the level of survival that is involved. If it is immediate such as the need for water and food then it is concrete. If it is more distant such as needing to survive through the development of skill, knowledge and expertise then survival becomes more abstract and needs to be broken down into concrete steps of accomplishment. So the long answer to your question is both as defined by individual need.

Chef, I think it uses both, especially as it applies to the Culinary world. You have to concretely perceive your surroundings and what you need to survive in the immediate situation, as well as abstractly percieve the next moments and what you are about to need for survival.
