ABSTRACT
According to the second law of thermodynamics, any transformation, however insignificant, results in a system change. Thus, every input transformation has a positive, negative, or neutral associated impact, which can modify the system performance in question and affect other related systems. In the case of sustainability studies, this system is made up of three different subsystems that are related to each other, namely, the environment, economy, and society. These subsystems are known as the three pillars (or spheres) of sustainability.
Similarly, as in the previous chapter on aquaculture, this chapter is a brief introduction to sustainability sciences. First, the concept of sustainability, its history, and different working definitions for the book are provided. Then, the three pillars of sustainability and the use of governance are explained as transversal tools to achieve sustainable production. Finally, the idea of sustainable aquaculture and its drivers are discussed.
