Geography is the science that explores the composition of geographical space. Its dynamics, its agents, its arrangements-nothing escapes the understanding of this discipline. This book is the result of a small foray into this field, where we explore the possible relationships between urban green areas and the real estate market. However, it was necessary to go back in time to understand the dynamics of present-day society in Santiago. As a researcher, I consider this work to be a fundamental part of the training of any professional in the field of geography.
