Over the last decade, the phenomenon called collaborative economy or sharing economy gained significant dimensions and crossed many sectors of economic and social life, creating new business models. Despite the growing interest, there is no single concept for its definition, manifestations, impacts and business models, while at the same time, digital platforms have allowed its sophisticated development. The seen emergence of sharing economy in Bulgaria brings out the need to study the phenomenon at the national level, its context, development, stakeholders. (...) The aim of this chapter is to shed light on the main manifestations and regulatory issues of the sharing economy in Bulgaria and to discuss its stage of development critically. The first part starts with a review of definition aspects and academic conceptualisation of the sharing economy and key issues. In the second part, aspects of the context and manifestations in the development of the phenomenon are discussed. Then, looking at several national examples of market players, an attempt is made to present the sectoral scope of the sharing economy and its development and to highlight the active stakeholders in the market. The study concludes with a discussion on the policies to be developed at the national level and future research to be carried out in order to catch the potential opportunities and overcome potential barriers.

In this study, we consider that enabling young people to experience direct contact with nearby natural environments can positively influence their knowledge and feelings about the biodiversity that occurs there, contributing to its protection and conservation for current and future generations. In this study, we explore how teenagers (n = 17) aged between 13 and 17 years old describe and perceive the nearby natural environment before and after an interpretive trail in Una, Bahia, Brazil. Participants were asked to draw the (...) Atlantic Forest with colored pencils on white paper and, based on the drawing, they answered the following questions: “What is in your drawing? and “What is happening in your drawing?,” in addition to other information such as the title of the drawing, difficulty of the activity, and sociodemographic aspects. Content analysis was used to analyze the information collected. From the drawings and responses of the participants, categories related to knowledge, experiences, and types of relationships with the visited place emerged. (shrink)
