The concept of sustainable development refers to doing what is necessary to try and guarantee that future generations will also be able to satisfy their needs. Taking this idea as a reference, the different areas of public administration, the business world and society as a whole are trying to spread the idea of respect for our natural resources as widely as possible. This book analyses the importance of sustainable development in optimising our future, discussing and proposing new paradigms, procedures and techniques addressed on the one hand to improving lifestyles, well-being or quality of life, and sustainable business practices, among other things, and on the other to preserving natural resources and ecosystems.
