Abstract
To be interested in the quality of life in a human ecology perspective is to study both the factors that intervene in the concrete expression of the well-being of populations and the conditions imposed on them both by the natural environment of their environment. living environment only by their social environment. Indeed, more than living conditions considered in the narrowly material sense of the term, people often define under the general term "quality of life" a composite reality that integrates not only the material framework in which their existence takes place but also all a set of representations and practices related to their health and their professional activity.The articles in this book are a reflection of an approach that attempts to examine the components of the quality of life that are the living environment and work and around which the daily life of people is articulated. The book begins with a text intended to refocus the interest of making the quality of life an object of study and is then organized in three parts which successively tackle the question of the quality of life related to the living environment, work and the resulting health consequences.All the texts presented offer a great diversity in the situations described both in the North and in the South, by the disciplines and methods convened, by the domain of the authors' belonging whether they are researchers or actors. They are not just a juxtaposition and will compel the reader to formulate cross-questions about problems that affect the quality of life in our contemporary societies.
