In front of the Riocentro convention center, where the official Rio+20 meetings and events are taking place, there is Parque dos Atletas or Athletes' Park: a space inaugurated last August to host the music festival Rock in Rio, and the first of many infrastructure works the city is creating for the 2016 Olympics.
Opened to the public but not a success in terms of audience (probably because it's two hours by bus from Rio), it hosts 41 spaces hosting delegations: from national governments (such as USA, Great Britain, France, United Arab Emirates, China, Qatar, Congo, Nigeria) to state governments from Brazil (namely Rio de Janeiro, Sao Paulo, Amazonian States, Minas Gerais), official United Nations offices (UNESCO, UN-HABITAT, UN-Women, UNFPA, to name a few), companies, and Brazilian organisms (like the agency which supports entrepreneurs and small companies, Sebrae).Many of such spaces are rather simple white tents, but the production company P&G Cenografia, which projected the State of Rio de Janeiro pavilion, seems to be following green design fads and came up with a massive structure covered with what they're saying are around 7,000 recovered pallets (which were bought from a Curitiba company through a tender).
The two buildings and the public space created around them has a total surface of 3,500 Sq. meters (37,600 Sq. feet). Inside of the spaces there are exhibitions and sitting areas also created with recovered pallets and with painted tires.
Outside, protruding cubes hold hanging plants, surrounded by screens showcasing the state government's work in areas such as sustainable agriculture. Take a look at the pics below.
