Rio de Janeiro




Rio de Janeiro is the capital of the state of Rio de Janeiro, Brazil's third-most populous state. Rio de Janeiro, or Rio, is the capital of the State of Rio de Janeiro and the second-largest city of Brazil. Rio is one of the most visited cities in the southern hemisphere, home to many famous landmarks such as the statue of Christ the Redeemer on the Corcovado mountain, which was named one of the New Seven Wonders of the World. In 2016, Rio de Janeiro will become the first South American and Portuguese-speaking nation to host the 2016 Summer Olympics.

Founded in 1565 by the Portuguese, the city was initially the seat of the Captaincy of Rio de Janeiro, a domain of the Portuguese Empire. Later, in 1763, it became the capital of the State of Brazil, a state of the Portuguese Empire. In 1808, when the Portuguese Royal Court transferred itself from Portugal to Brazil, Rio de Janeiro became the chosen seat of the court of Queen Maria I of Portugal, who subsequently, in 1815, under the leadership of her son, the Prince Regent, and future King João VI of Portugal, raised Brazil to the dignity of a kingdom, within the United Kingdom of Portugal, Brazil, and Algarves. Rio stayed the capital of the pluricontinental Lusitanian monarchy until 1822, when the War of Brazilian Independence began. This is one of the few instances in history that the capital of a colonizing country officially shifted to a city in one of its colonies. Rio de Janeiro subsequently served as the capital of the independent monarchy, the Empire of Brazil, until 1889, and then the capital of a republican Brazil until 1960 when the capital was transferred to Brasília.

Rio de Janeiro had been a long time capital of Brazil and has therefore attracted a lot attention and investments from profitable companies. Till the end of the 19th century, Rio was the richest state in Brazil before Sao Paulo took over. Rio basically invests a lot in sugar-cane production. It has large plantations in the area of Campos. Production of Oranges too forms a major part of the farming sector. Coffee was once a key industry but due to environmental factors, it has lost its importance. Other food grains are also produced but not in large amounts to be sold on a large scale. Among the livestock industry, there are various animal farms all over the city. Fishing of sardines is also a significant part of the Brazilian economy.

In recent years, Rio de Janeiro has massively invested in public transportation. In 2014, the city received a Sustainable Transport Award for its second of four BRT systems, Transcarioca. The corridor crosses dense and well-established areas with a historical deficit of quality public transportation.  Serving 27 neighborhoods, Transcarioca has 47 stations and spans 39 km of segregated roads integrating metropolitan rail systems, subways, Rio’s first BRT system, TransOeste, and most notably connects with the International Airport located on an island in Guanabara Bay to provide easier access to many areas in Rio de Janeiro.

Since winning its bid for the 2016 Olympic Games seven years ago, Brazil’s Rio de Janeiro has undergone a construction boom, including new sports venues, subway connections, and more infrastructure. Though marred in part by political scandal and a suffering economy, Rio largely completed its intended projects. Here are some of the biggest changes.

One of the flagship transportation efforts, Rio built a new subway extension linking popular beach areas with the neighborhood where the Olympic Park is located. Though originally intended to open to the public ahead of the Games, repeated delays forced a later completion date than hoped and will only be open to athletes and Olympic spectators.


Rio de Janeiro uses IBM's Smart Cities technology to coordinate its city services in real-time, from responding to emergencies to unsnarling traffic. Perhaps IBM's expertise made the difference in Rio. The computing giant is just one player in the expanding smart systems market, but the operations center (the only one of its kind) is its unique advantage. The logic is that if the Smart City model can work in a large city like Rio, especially during Carnaval, it can be applied anywhere. IBM has reported that it is already productizing the model and is able to scale it to small and medium-sized cities. At the behest of IBM, Rio even installed a chief operating officer to oversee the operations center, allowing it to run autonomously.

The Rio de Janeiro Low Carbon City Development Program (LCCDP) is a systems-approach to low carbon development, including a framework and set of comprehensive requirements to help the city to plan, implement, monitor, and account for low carbon investments and climate change mitigation actions across all sectors in the city over time. The Rio LCCDP, the specifics of which are captured in the Rio LCCDP Program, was launched in June 2012 at the Rio+20 conference with the presentation of its compliance with the new LCCDP Assessment Protocol, including the achievement of multiple International Organization for Standardization (ISO) accreditations. The ISO-certification makes the Program a prototype for a business model that can be replicated in cities around the world.
