The production of the space we inhabit is the result of various processes accumulated over time in our materiality and social relations. Space is composed of the indissociable set between the occupied area (formed by reliefs, ecosystems, atmospheric dynamics) and the processes of occupation (relative to relations of power, culture, politics, social, and economic): an amalgam that registers, records, and graphs on the ground its unique and exclusive mark, which we commonly call landscape or, more deeply, geography – the graphics on the earth. This landscape is made of visible things and, also, of immaterialities that result from social relations and involve power, economic value, political and cultural interests. Geodiversity, among many definitions, can be understood as the diversity of geological and geomorphological features and processes that interact with culture, modeling the landscape. Rio de Janeiro does not escape this process, expressing very well in its geography the interweaving of buildings over rocky massifs, coastal lowlands, and the different ways of living in such distinct spaces. Each valley carved by a river or each lowland, with beaches and restingas, nestles and accommodates parts of our city and influences our lives. The rocky formations and their dynamics interact intensely with urban daily life, whether with the waterfalls that cool their visitors or the landslides and floods that afflict us in hot and rainy summers. It is not an easy task to inhabit Rio de Janeiro, a city where the relief is not just a scenery — it is the protagonist of the life that pulses between mountains, valleys, beaches, and lowlands. Since its foundation, the city has been configuring itself over this rugged terrain and the influence of these physical dimensions are present, designing the stage of events and shaping its own construction. It is in this unique relief that we inscribe our presence, diverting rivers, filling in marshes, beaches, and mangroves, climbing to the peaks and descending into the subsoil. We were and are forceful in the construction of our own living space. The geological history of Rio de Janeiro dates back to very ancient tectonic movements in continental collisions that forged, in high temperature and pressure, our rocks. Later, the separation of the continents and the opening of the Atlantic Ocean completely altered the relief and raised our sugar loaves, hunched hills, peaks, and serras. Tropical rains, storms, and tempests sought to lash and destroy these formations over the millions of years of evolution of this landscape. Valleys were carved, sediments distributed in low areas, rivers, marshes, and bays formed. Forests and associated ecosystems occupied their habitats with exuberant flora and abundant fauna. Humans recorded their first traces in the Rio de Janeiro and Guanabara region around 8,000 years ago and are associated with the global warming that the planet experienced with the end of the last glaciation. The tropicalization of these environments attracted human hordes who arrived through the Amazon and occupied the hinterland of Guanabara given its abundance of resources: mangroves, marshes, fish, crustaceans, fresh water from various rivers that reached the bay. After these prehistoric peoples came the tupinambás, temiminós, and other indigenous nations who occupied our territory. But this historical account is already in the gallery
and here we will deal with the spatial dimension of the facts, thinking about the geography of these processes.
