Boundaries is a quarterly international journal on contemporary architecture, with texts in English and Italian, that offers a critical view over the architectures that today deal, in many different ways, with the challenges of the contemporariness and of sustainability intended as a balance between cultural, environmental, economic and social matters. A hint to the structure of the journal: every issue will address a monographic theme, around which the topics of the articles will be focused. The section "Ideas" proposes some food for thought, crossing different disciplines. The section "That was the year..." will address the history of the 20th Century and will always be present: it will focus each time on a different event that has been particularly important, an achievement that must not be forgotten because it still constitutes an important lesson. Boundaries starts with the history of contemporary architecture in Africa. The signs of a possible change in progress can be felt in many places and countries of this big continent and show how the logic of the global consensus is not the only possible alternative. In this first issue: the commitment, the quality of the architectural research, the social awareness of the profession, but also the contradictions one must deal with if one chooses to be an architect in this way.
