It is the outcome of five centuries of nature-human interaction. Last week UNESCO elected part of the city as a World Cultural Heritage.<\/p>\n<p>It is quite meaningful that most of the selected images show the high biodiversity Atlantic Rainforest that have regenerated after centuries of natural resources exploitation and agricultural practices that had eliminated most of the native land cover (<a href=\"http:\/\/whc.unesco.org\/en\/list\/1100\/\" target=\"_blank\">http:\/\/whc.unesco.org\/en\/list\/1100\/<\/a> viewed 07.05.2012). Actually the forests are fragmented, surrounded by dense urban occupation, and under pressure of further expansion repeating the same mistakes made in the past. The urbanized areas occupy mainly the lowlands, where ocean lagoons and wetlands were land filled with the devastation of several hills. One of the elected sites, the <em>Flamengo<\/em> <em>Park<\/em>, is a huge 1.2 km\u00b2 created land, where the world renowned landscape designer <a href=\"http:\/\/en.wikipedia.org\/wiki\/Roberto_Burle_Marx\" target=\"_blank\">Roberto Burle Marx<\/a> was responsible for the magnificent gardens.<\/p>\n<figure id=\"attachment_321\" aria-describedby=\"caption-attachment-321\" style=\"width: 584px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-321\" title=\"Figure 1\" src=\"http:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2012\/07\/Figure-14-630x345.jpg\" alt=\"\" width=\"584\" height=\"319\" \/><figcaption id=\"caption-attachment-321\" class=\"wp-caption-text\">View from the Tijuca National Park, Christ the Redeemer (left) and Sugar Loaf (far center): reforested hills and the city.

Nature took care of the rest, with the regeneration of vast areas of the two major massifs: Tijuca and Pedra Branca. Both are protected areas today. Tijuca National Park is one of the UNESCO elected sites. In the last 25 years a successful city reforestation program called \u201cMutir\u00e3o Reflorestamento\u201d (&#8220;common effort to restore forests&#8221;) has effectively replanted trees on slopes to prevent landslides, mainly close to the<em> favelas<\/em>. It is a social-ecological program because local people are hired and trained to work in the planting and monitoring process, becoming stewards of the forest.<\/p>\n<figure id=\"attachment_312\" aria-describedby=\"caption-attachment-312\" style=\"width: 584px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-312\" title=\"Figure 2\" src=\"http:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2012\/07\/Figure-2-630x304.jpg\" alt=\"\" width=\"584\" height=\"281\" \/><figcaption id=\"caption-attachment-312\" class=\"wp-caption-text\">View from the favela (slum) Santa Marta, with formal city in the lower areas.

The city has diverse environments, with pleasant forests and nice parks contrasting with arid, hot and noisy streets where the majority of the population lives. Most of the time the city is fairly hot. For instance, today is winter and the temperature is 29\u00b0C (84.2\u00b0F) at mid-day. I live very close to the forest, where it is quite pleasant with many trees, birds and insects. Native and invasive species are present, and should be permanently managed. Biodiversity abounds even close to the ecosystem remnants. In fact, if we let the windows open in the morning, monkeys (<em>Cebus apella<\/em>) come inside our apartment. Many residents feed them, consequently they keep coming back after easy junk food. Meanwhile, if I walk down one block, the traffic jam is constant, the temperature is much higher, and the street trees are old, under severe pressure in unsuitable situations, and many are dying and not being replaced.<\/p>\n<figure id=\"attachment_313\" aria-describedby=\"caption-attachment-313\" style=\"width: 300px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-313\" title=\"Figure 3\" src=\"http:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2012\/07\/Figure-3-300x200.jpg\" alt=\"\" width=\"300\" height=\"200\" \/><figcaption id=\"caption-attachment-313\" class=\"wp-caption-text\">Monkey in our balcony, with an onion.

I am not sure how they acknowledge and value the ecosystems services the forests and the urban trees provide. There is a great opportunity for further research about urban ecology and urban\/regional landscape planning in Brazil, but there still isn\u2019t formal education in these fields. Urban biodiversity and human-nature relations are not current issues in the majority of the Brazilian cities either, where in the last 20 years shopping malls and manicured gardens of gated communities are replacing open public spaces as recreation areas.<\/p>\n<p><strong>Urban Nature is not a Rio de Janeiro Decision-maker&#8217;s Priority<\/strong><\/p>\n<p>The decision makers in Rio de Janeiro do not make urban nature a priority. There is a lack of real comprehension of the role of biodiversity for a healthy city. The urbanized areas are subject to frequent floods and landslides because of the historic change in land use and vegetation cover. The World Cup and Olympic games that will take place here in the coming years drive a fast urban expansion that follows the same land cover pattern transformation in the remaining lowlands located in the western zone, in the <em>Jacarepagu\u00e1 <\/em>and<em> Guaratiba<\/em> watersheds. Wetlands are being filled to create land for new expressways (cars and BRT\u2019s) and by the real estate speculative process. The last legally protected mangrove remnant is under threat of excessive salinization because a new highway was built with traditional engineering techniques that interfere with the hydrologic flows, block the fresh water in the residential side, and, according to residents, cause more severe and recurrent floods. Other roads are under construction with no care for the landscape ecological processes and flows, eliminating biodiversity and changing water flows.<\/p>\n<figure id=\"attachment_314\" aria-describedby=\"caption-attachment-314\" style=\"width: 584px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-314\" title=\"Figure 4\" src=\"http:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2012\/07\/Figure-4-630x413.jpg\" alt=\"\" width=\"584\" height=\"382\" \/><figcaption id=\"caption-attachment-314\" class=\"wp-caption-text\">Aerial view of Jacarepagu\u00e1 lowlands: Modernist urbanization based on car transportation, gated communities and shopping malls.
