are living in challenging times in which cities play a crucial role, as so many authors of The Nature of Cities have pointed out from different perspectives. In this international blog, contributors have presented and discussed examples that are popping up around the worldof social-ecological oriented research, planning, and design, wherein biodiversity is treated as fundamental. Many of those case studies come from local residents who want more livable places to raise kids in healthy and diverse environments.However, many cities have remained in the old modernist sprawl paradigmbased on high consumption economies, gated communities with homogenized gardens, and automotive transportation that requires costly infrastructureknown as business-as-usual. The surrounding ecosystems remnants and productive lands are eradicated in this process. Also, old urban areas have been transformed, destroying their history and culture. Gentrification in renovated regions is another negative factor, displacing residents and small businesses while ceding room for a globalized culture and international brand stores. This globalized trend widens the social gap even farther, especially in poorer countries, where it is already abyssal.Our planet is urban not only because the Biosphere is giving way to built surfaces, but also because the political and economic decisions are largely taken by city dwellers.I consider ecological illiteracy to be one of the main drivers of the disconnection and disregard of our Home: our planet, our region, our city, our neighborhood, our street or our own home. Or even with our own selves!How can people connect with nature and its processes if they spend their life in air-conditioned (or heated) built boxes, apart from biodiversity and social diversity? How can they develop and act on their Biophilia in artificially built and controlled landscapes? [Biophilia is the innate and genetically determined affinity of human beings with the natural world (E.O. Wilson)] Much has been written, published, and discussed in conferences about those issues (see for instance Tim Beatley in this blog).Urban landscapes and reconnection with NatureFor me, the Popes call to care for our home is more than a metaphor for the Planets degradation and the related risks to Humanity. It is time to care for our home at all scales, including the ecological restoration of our urban landscapes.In Brazil, the number of urban dwellers that are engaging in growing organic food, fighting for ecosystem restoration and water conservation, and getting together to learn and exchange experiences has been growing exponentially. As everywhere, in this country, social media is helping people to communicate among themselves about their findings and experiences with Nature and natural processes in multiple ways. We have very positive results on the fields that actually enhance urban landscapes ecologically and socially: publications and courses on related themes are starting to pop up around the country; leaders are assuming important roles, participating in actions and policy elaboration; volunteers are expanding their work in a society without a tradition of social work.There are lots of good examples that are more powerful every day, as I have already mentioned in my previous posts in this blog.
