Porto Alegre

According to the Köppen climate classification, Porto Alegre has a humid subtropical climate (Cfa) characterized by its high variability, but with well-defined seasons and evenly distributed rain throughout the year. The presence of Lake Guaíba contributes to increase the humidity of the air.[18] The city experiences the most prominent difference among seasons and between temperature extremes among all Brazilian capitals. One reason for that is its much more southerly position relative to the rest of the country, which also contributes for the occurrence of 14 hours of daylight in December and 10 hours in June.[19] Due to a large depletion in the ozone layer over the south of Brazil, a result of the Antarctic ozone hole,[20] the population is occasionally dangerously exposed to extremely high UV radiation.[21]

The winter is mild to cool, windy, rainy and quite changeable, which is also a feature of this time of the year. Usual winter temperatures range from 10 °C (50 °F) to 19 °C (66 °F). In the coldest days of the year the temperature may fall slightly below zero, like in 2012, when it recorded −0.7 °C (31 °F).[22] The summers are very hot, with temperatures that go up to 30 °C (86 °F), sometimes reaching 40 °C (104 °F).[23] Sometimes, summer usually has irregular rains and periods of drought.[24] Fall tends to be as changeable as winter, but is typically warmer. Spring is usually very rainy, with thunderstorms, strong winds and hailstorms.[25][26][27] The climate of Porto Alegre is very affected by El Niño phenomenon, with flooding in some neighborhoods of the city, especially in the islands in the Lake Guaiba.[28][29][30] However, a drainage system and a wall along the Historic District were built after a major flood in 1941 that devastated the city, preventing further damage.[31][32]

Snow is very rare, sometimes confused with sleet.[33] The only snowfall events in Porto Alegre were in 1879, 1910, 1984, 1994, 2000 and 2006, and few of them featured accumulation.[34] However, frost sometimes occurs in the city.[35] Occurrence of radiation fog is common, causing several delays in early flights. Unlike other large Brazilian cities much farther north, notably Brasília, São Paulo, and Rio de Janeiro who observe a pronounced summer maximum in precipitation amounts, the city of Porto Alegre experiences a prominent winter maximum in precipitation values and cloud cover, for the summer season is primarily hot and dry; though evidently high humidity levels often give a distinct mugginess to the air and negatively impacts air quality. Annually Porto Alegre receives an average-total precipitation amount of 1,425 millimetres (56.1 in). This average makes the city slightly wetter than Rio at 1,172 millimetres (46.1 in) yet, to a very small extent, drier than both São Paulo at 1,457 millimetres (57.4 in) and Brasilia at 1,557 millimetres (61.3 in).[36]

The highest recorded unofficial temperature was 42.6 °C (108.7 °F),[37] while the lowest official recorded temperature was −4.0 °C (24.8 °F) on July 11, 1918. [38]

Moinhos de Vento Park

Porto Alegre lies in a transitional area between the subtropical forest and the Southern Brazilian grasslands (pampa). A number of conservation programmes have been established to protect native trees. Many of the city's avenues have been planted with different tree species. One striking example of this is Teresópolis Avenue, where bottle trees have been planted. The city is covered in green vegetation and Lapacho and Jacaranda are the main species that can be found locally. The trees from the hills are protected. Two environmental conservation areas can be found in this city: "Delta do Jacuí" (Jacuí Delta) State Park and Lami Biological Reserve.[42]

The urban area has many parks and plazas, making Porto Alegre one of the greenest provincial capitals in Brazil. The first city squares date from the second half of the 18th century and were originally large public spaces used as food markets. The city has 39 km² (9,600 acres) of green space, occupying 31 percent of the city's area. This is an average of 17.6 m² per person. More than one million trees line the public streets and SMAM plants an average of 30,000 seedlings each year. The four main parks are: Parque Farroupilha, a 37-hectare (91-acre) park; Jardim Botânico (The Botanical Garden of Porto Alegre), with some 725 species of vegetation on about 43 hectares (110 acres) of land; and Parque Marinha do Brasil (The Brazilian Navy's Park), a vast park of more than 70 hectares (170 acres) which offers a wide variety of sports fields and tracks. The city's cycleway is called the Caminho dos Parques, which at over 5 km (3 miles) long links the Moinhos do Vento, Farroupilha and Guaíba shore parks.[43]

The Lami José Lutzenberger Biological Reserve was established in 1975 in the Lami neighborhood of Porto Alegre, named after the local agronomist and environmentalist José Lutzenberger. It was the first municipal reserve in Brazil. The reserve covers 179 hectares (440 acres). It reopened in April 2002 after being closed for more than ten years to allow its ecosystems to recover.[44] The reserve conserves nature and supports research and environmental education.[45]

Sewer service is available to 87.7 percent of the city, and 100 percent of the population is serviced by treated water.[46] While in most Brazilian cities the water is supplied by large state companies, in Porto Alegre the Municipal Department of Water and Sanitation Services, (DMAE) is the provider. It is the largest municipal water supplier in the country and enjoys operational autonomy and financial independence. As a separate entity from the municipal government it can make its own decisions on how to invest revenues it has collected, and such decisions are not directly subject to interference from the municipality. It receives no subsidies and makes no payments to the municipality itself. As a municipal undertaking, DMAE enjoys tax-exempt status, which allows it to keep water prices lower.[47]

In 2010, the Inter-American Development Bank (IDB) approved a US$83.2 million to support the Integrated Socioenvironmental Program of Porto Alegre. The program will be carried out by the Municipal Department of Management and Strategic Support and will focus on improving water quality in Guaíba Lake and the Cavalhada River, developing urban infrastructure to reduce flood risk along the Cavalhada River, improving the environmental management in the Municipality of Porto Alegre, and promoting efficient municipal water, sanitation and storm drainage services. This program will improve the quality of life of the population of Porto Alegre by restoring water quality along the west side of Lake Guaíba and directly benefitting more than 700,000 residents through expanded public sanitation services and urban environmental improvement.[48]

The Jacuí estuary contains the Jacuí Delta State Park, which in turn contains the Banhados do Delta Biological Reserve, a fully protected area which covers the islands of Pólvora and Pombas.[49]

Motor vehicles are responsible for the main atmospheric pollutant emissions. The city has the second worst air quality in Brazil, after only São Paulo.[50] The use of new buses along dedicated busways has decreased pollutants as there is less idling time. SMAM (the Municipal Council of the Environment) has encouraged the use of the cleanest fuels and has played a role in monitoring pollution levels.

A partnership between SMAM, the Federal University of Rio Grande do Sul, the State Environmental Protection Foundation (FEPAM) and Petrobrás has created a network of five air monitoring stations in Porto Alegre. By utilizing a Petrobrás product called city diesel, sulphur levels in the air have dropped from 1.2 percent in 1989 to 0.5 percent. Hybrid buses which run on both diesel and electricity are also being considered for the future. Because Porto Alegre has a ready supply of natural gas, the city's taxi fleet is gradually being converted to it from gasoline.[51]

According to the 2010 IBGE Census, there were 1,365,039 people residing in the city of Porto Alegre.[52] The census revealed the following numbers: 1,116,659 White people (79.2%), 143,890 Black people (10.2%), 141,411 Pardo (Multiracial) people (10%), 4,062 Asian people (0.3%), 3,308 Amerindian people (0.2%).[53] In 2010, the city of Porto Alegre was the 10th most populous city in Brazil.[54] In 2010, the city had 269,519 opposite-sex couples and 1,401 same-sex couples. The population of Porto Alegre was 53.6% female and 46.4% male.[53]

Porto Alegre is mostly composed of Brazilians of European descent. Its colonization started in the mid-18th century, mostly with the arrival of Portuguese colonists from the Azores Islands. From 1748 to 1756, 2,300 Azoreans were sent to the region by the King of Portugal to protect Southern Brazil from neighboring invaders.[55] These colonists, mostly composed of married couples, established the city of Porto dos Casais (literally translated "harbor of the couples"), nowadays Porto Alegre. In 1775, 55% of Rio Grande do Sul's population was of Azorean Portuguese origin.[56] Porto Alegre was composed mainly of Azoreans and their African slaves until the first half of the 19th century.

Residents of Porto Alegre

The first non-Portuguese people to settle Rio Grande do Sul were German immigrants. In 1824, the first immigrants from Germany arrived in Porto Alegre, but they were sent to what is now the city of São Leopoldo (28 km (17 mi) away). From 1824 to 1914, 50,000 Germans arrived in Rio Grande do Sul.[57] Most of these colonists had rural communities in the countryside of the State as their first destination. The large rural exodus in Brazil in the early 20th century brought many German-descendants to Porto Alegre and, nowadays, they compose a large percentage of the population.[58]

The second largest group of immigrants who arrived in Porto Alegre were the Italians. They started immigrating to Brazil in 1875, mainly from the Northern Italian Veneto region.[59] As the Germans, Italians were also first sent to rural communities, mainly in the Serra Gaúcha region. After some decades, many of them started to migrate to other parts of Rio Grande do Sul, including Porto Alegre. Minority communities of immigrants, such as Central Europeans from Poland[60] and Eastern Europeans from Ukraine and Jews; Arabs from Palestine, Lebanon and Syria; Asians from Japan; as well as Spaniards arriving after the Civil War also made Porto Alegre their home.[61][62] According to an autosomal DNA genetic study from 2011, the ancestral composition of the population of Porto Alegre is: 77.70% European, 12.70% African and 9.60% Native American.[63]

A feature of public administration in Porto Alegre is the adoption of a system of popular participation in the definition of public investment, called the Participatory Budget. The first full participatory budgeting process was developed in the city starting in 1989. Participatory budgeting in its most meaningful form took place in the city from 1991 to 2004.[69] Participatory budgeting was part of a number of innovative reform programs to overcome severe inequality in living standards amongst city residents. One third of the city's residents lived in isolated slums at the city outskirts, lacking access to public amenities (water, sanitation, health care facilities, and schools).[70]

Participatory budgeting in Porto Alegre has occurred annually, starting with a series of neighborhood, regional, and citywide assemblies, where residents and elected budget delegates identify spending priorities and vote on which priorities to implement. Porto Alegre spent about 200 million dollars per year on construction and services, This money is subject to participatory budgeting, unlike the annual spending on fixed expenses such as debt service and pensions, which is not subject to public participation. Around fifty thousand residents of Porto Alegre took part at the peak of the participatory budgeting process (compared to 1.5 million city inhabitants), with the number of participants having grown year on year since 1989. Participants are from diverse economic and political backgrounds.[71][72] Although participatory budgeting appears to continue in the city today, two prominent scholars on the process have stated that "after the defeat of the Workers' Party in late 2004, a politically conservative coalition maintained the surface features of PB while returning the actual functioning of the administration to more traditional modes of favor-trading and the favoring of local elites."[69]

The participatory budgeting cycle starts in January and runs throughout the year in many assemblies in each of the city's 16 districts, dealing with many areas of interest to urban life. The meetings elect delegates to represent specific neighborhoods. The mayor and staff attend, in order to respond to citizens' concerns. In the following months, delegates meet to review technical project criteria and district needs.[71]

Administrative Center of Rio Grande do Sul

City department staff may participate according to their area of expertise. At a second regional plenary, regional delegates prioritize the district's demands and elect 42 councillors representing all districts and thematic areas to serve on the Municipal Council of the Budget. The main function of the Municipal Council of the Budget is to reconcile the demands of each district with available resources, and to propose and approve an overall municipal budget. The resulting budget is binding, though the city council can suggest, but not require, changes. Only the Mayor may veto the budget, or remand it back to the Municipal Council of the Budget (this has never happened).[71]

A World Bank paper suggests that participatory budgeting has led to direct improvements in facilities in Porto Alegre. For example, sewer and water connections increased from 75% of households in 1988 to 98% in 1997. The number of schools quadrupled since 1986.[70] According to Fedozzi and Costa, this system has been recognized as a successful experience of interaction between people and the official administrative spheres in public administration and, as such, has gained a broad impact on the political scene nationally and internationally, being interpreted as a strategy for the establishment of an active citizenship in Brazil. The distribution of investment resources planning that follows a part of the statement of priorities for regional or thematic meetings, culminating with the approval of an investment plan that works and activities program broken down by investment sector, by region and around the city. Also according to Fedozzi, this favors:[73][74]

The high number of participants, after more than a decade, suggests that participatory budgeting encourages increasing citizen involvement, according to the paper. Also, Porto Alegre's health and education budget increased from 13% (1985) to almost 40% (1996), and the share of the participatory budget in the total budget increased from 17% (1992) to 21% (1999).[70]

Despite being the pioneering experiment of participatory budgeting, Porto Alegre like many other examples does not have guaranteed sustainability. The positive impact has dwindled since 2004 due to funding changes and decreasing government commitment. Participatory budgeting has been suspended in Porto Alegre since 2017 [75]

In Brazil, there are also a few coal-fired plants, fuel-oil fired plants and one nuclear facility. Increased utilization of natural gas and other sources is planned in order to reduce Brazil's overdependence on hydroelectric power. In 1999, a natural gas pipeline from Bolivia to Brazil was completed, with its terminus in Porto Alegre. Brazilian investment group Central Termoeletrica Sul (CTSul) has plans to invest US$698 million in a 650MW coal-fired power generation plant in Cachoeira do Sul, located in Rio Grande do Sul.[82]

The largest wind energy park in Brazil, which is being built east of Porto Alegre in Osório, will add 150 megawatts (MW) to the Brazilian energy matrix. The production represents 5 percent of the energy consumed in the state of Rio Grande do Sul and would be sufficient to meet two-thirds of Porto Alegre's energy demands. The Farm opened in 2008 with 75 2MW turbines and has been approved for a 300MW expansion which would make it the largest wind farm in the region. The project is part of the Alternative Energy Sources Program (Proinfa) from state-owned Eletrobrás, which will purchase the energy produced for the next 20 years.[83]

Porto Alegre was one of the first cities in Brazil to develop a recycling program and has been acknowledged as having the best management practices in the country.[84] The city produces about 1,600 tonnes of household waste per day.[85] Since 1997, all non-recyclable waste has been disposed of in landfill sites. Infiltration into the soil is prevented by the double-walled construction of a clay layer and a high-density polythene geo-membrane, the lowering of the water table and the draining off and treatment of any effluent.[86]

Pubs on Calçada da Fama during the day

Porto Alegre is well known in Brazil for its diverse nightlife. The city's clubs, pubs, bars and restaurants provide entertainment for a wide range of tastes and budgets, going from the cheap, traditional beer-'n-bite in a corner bar to all-night raves, and nightclubs. In the "SoHo" area of Porto Alegre, there is a block full of bars, restaurants and clubs.[89]

In Cidade Baixa (translates as "Downtown") neighborhood, the historical street João Alfredo has many options. Discotheques include Dado Bier, Beco, Opinião and Nega Frida. The corner between Gal Lima e Silva Street and República Street is the center of the neighborhood's nightlife. Cavanhas, Pingüim, Copão, Cotiporã and Panorama are some of the bars. To dance MPB (Brazilian popular music), historical street João Alfredo has many options.[90]

In Calçada da Fama, Padre Chagas Street is full of more fashionable bars, like Lilliput and Dado Pub. Goethe Avenue has a concentration of bars (Tri Bar, Arsenal, Dolphin's) and dance clubs. There is also a vibrant more alternative scene with clubs such as Ocidente, Beco, Anexo B and Cucko. Rua Fernando Gomes has a concentration of pubs, cafes, bars. Avenida Osvaldo Aranha, alongside the Parque Farroupilha and near the Federal University has bars with a predominantly young and trendy clientele.[91] Moinhos de Vento is one of the richest neighborhoods in the city. Its bars and clubs are more likely to be fashionable, including upscale Pink Elephant Club, Faro and Box 21, which feature mostly house music. Along Padre Chagas Street, people can find typical Irish pubs and cafes.[92] A fictionalized view of the Porto Alegre nightlife could be seen in the Érico Verissimo's novel Noite.

Near Oswaldo Aranha street, in the Farroupilha Park, the Araujo Viana Auditorium is an auditorium for concerts, performances and meetings. Designed by architects Moacir Moojen e Carlos Fayet, was inaugurated in March 1964, making it an important space for cultural events. The original project for the auditorium was built where nowadays Legislative Assembly is, however, it was relocated to the Farroupilha Park in 1964.[93]

There are three important universities in Porto Alegre: the Federal University of Health Sciences of Porto Alegre (UFCSPA), the Federal University of Rio Grande do Sul (UFRGS) and the Pontifical Catholic University of Rio Grande do Sul (PUCRS) all of which ranked among the top universities in Brazil and Latin America. UFRGS is also one of the 3 main universities in the country for post-graduation work. The PUCRS technological park – TECNOPUC – is one of the largest scientific and technological parks in Latin America with interaction of graduate courses, research and innovation. PUCRS is also one of the best universities for air transport and pilot formation in the world. Other very important universities are the Lutheran University of Brazil - (Universidade Luterana do Brasil) - ULBRA and UNISINOS, among other university centers.[94]

This is an important museum with a large collection of archaeological artifacts and photographs of Porto Alegre's old times. Its historical building, dating from 1845 to 1855, is one of the few intact relics of colonial architecture inside the modern urban environment.[97]

Rio Grande do Sul Memorial

This museum displays a huge collection of documents, maps, objects, prints and other items related to the state's history. Its building, designed by Theodor Wiederspahn, is one of the finest examples of eclectic architecture in the city.[98]

Iberê Camargo Foundation

An iconic landmark in the southern part of Porto Alegre, the Iberê Camargo Foundation houses the permanent installation of gaucho artist Iberê Camargo. It also hosts traveling exhibitions which change several times a year. The building, designed by Portuguese architect Álvaro Siza was opened in 2008 and offers views of the Guaiba river as well as downtown Porto Alegre.[99]

Luiz Carlos Prestes' Memorial

Projected by Oscar Niemeyer, the Luiz Carlos Prestes' Memorial is a recent addition to the city' cultural landscape. Besides the wall presentation of Prestes' life, a hall for cultural, social and political events is placed to the citizens of Porto Alegre.[100]

The Porto Alegre Carnival began in the 18th century with the entrudo, a prank brought over by the Portuguese from the Azores, whereby people threw flour, water, and "limão de cheiro" missiles at each other. At the end of the 19th century, two important Carnival associations were born. Rivalry between the two long dominated the city's Carnival. The corso, a parade of floats down Porto Alegre's streets, was a celebration enjoyed by the more well-to-do of the city's inhabitants.[101]

One of the most important Carnival personalities is King Momo. At the beginning of Carnival, usually in February, he receives the keys to the city from the Mayor of Porto Alegre, symbolically governing the Carnival during the four days of revelry. Vincente Rao was the most popular King Momo.[102]

The traditional beverage is chimarrao, a South-American caffeine-rich infused drink. The Chalet of the XV de Novembro Plaza is located along the Glênio Peres Square, it is one of the most traditional bar-draught beer-restaurants in the city, where the last "lambe-lambe" photographs of the region work. "Lambe-lambes" are photographers who develop pictures outdoor using the oldest method known. In the Bavarian style, with art nouveau traits, the centenary Chalet was built up on a demountable steel structure, keeping its original chandeliers and tiles even nowadays.[103][104]

Salgado Filho International Airport

Port of Porto Alegre

Salgado Filho International Airport serves commercial flights to most major cities all over Brazil and to smaller cities in the South of the country. There are also international flights to other South American countries, Panama, and Portugal.[112]

Canoas Air Force Base - ALA3, one of their most important bases of the Brazilian Air Force, is located in the nearby city of Canoas.

The Port of Porto Alegre is situated in the Eastern margin of Guaíba Lake. The port lying on the eastern bank of the Guaíba lake at the point where its waters empty into the huge Lagoa dos Patos is one of Brazil's largest ports. Located near the main access roads to Porto Alegre, it is 4 km (2 mi) away from the Salgado Filho International Airport and has access to the light railway station, through the docks of Mauá and Navegantes. Its geographical position enables a permanent traffic between Porto Alegre and Buenos Aires, transporting steel-industry products and mainly agricultural produce.[113][114]

Porto Alegre has a rapid transit system operated by Trensurb, which links downtown Porto Alegre to its northern neighborhoods and to cities to the north of the metropolitan area, as Canoas, Esteio, Sapucaia do Sul, São Leopoldo and Novo Hamburgo. The line has stations at strategic spots, such as: the Public Market, the bus station, the airport and many other important and urban spots throughout Porto Alegre and the other cities the metro covers. The line is built at surface level (30 km, totally segregated) and elevated (12 km).

Trensurb is operated jointly by the federal government, the state government of Rio Grande do Sul and the city of Porto Alegre through the company Trensurb S.A. (Company of Urban Trains of Porto Alegre S.A.) and has 22 working stations, with a total extension of nearly 43 kilometres (27 mi),[115] carrying about 130,000 users a day. Building of the (sole) Line 1 of the metro started in 1980. The choice of path was made to relieve the heavy traffic of highway BR-116, which already presented serious problems with the transit at the time. The line was inaugurated on March 2, 1985, between the Central Public Market and Sapucaia do Sul. In December 1997, it was extended to Unisinos. An extension of 2.4 miles (3.9 km) São Leopoldo–Museum was added in November 2000, after two months of trial service.[116] As of 2013, an extension to Novo Hamburgo is being completed, with the first station already fully functional.[117]

A metro system inside Porto Alegre only is currently planned and it is already subject of much publicity and speculation.[118] However, no project has been approved so far and the beginning of the constructions is yet undefined.

There are two federal highways in the city, BR-290 and BR-116, both running close to its northern and northwestern border. The small number is due to the inexistence of many destinations southeast or south of Porto Alegre (considering the landmass east of Lagoa dos Patos),[119] if not for the cities of Pelotas (the third-biggest in population in the State) and Rio Grande (which hosts the State biggest port). Nonetheless, when coming from west, both highways bond in the neighbor municipality of Eldorado do Sul, running mostly jointly within the borders of Porto Alegre, only coming to separate at the very interchange to Canoas. This way, BR-116 has virtually no sole run within Porto Alegre.

BR-290 highway runs east–west across the state, linking the northeast coast of the state to the Uruguay–Argentina–Brazil border. It runs close to the northern border of the municipality. Coming from west, as it reaches the urban area of Porto Alegre, BR-290 highway becomes a high-standard 100 km (62 mi) long freeway that connects to the coast and to the BR-101 highway. The latter is an important way to get to Porto Alegre from the north of the country, by the city Osório. BR-101 connects to Curitiba, Florianópolis and northern Santa Catarina state, and has been recently upgraded to highway standards, with multiple lanes. By entering the BR-290 freeway/BR-101 system, and the other highways it connects to, it is possible to drive from Porto Alegre to as far as Rio de Janeiro or Belo Horizonte almost entirely through 4-lane (or more) highways.

The other road, BR-116, is a longitudinal highway, running northeast–south across the state, linking Porto Alegre to several satellite cities and other Brazilian capitals to the north, and Pelotas and Uruguay to the south. Within the municipality, it only touches the northwest side of the city, close to the end of Rio Gravataí (Gravataí River), sharing its entire run with BR-290, only separating when heading north onto Canoas.

A third road, BR-448, is currently under construction.[120] BR-448 is planned to connect the northeast of Porto Alegre to Sapucaia do Sul, as an alternative to BR-116, notably jam-packed on its Canoas-Novo Hamburgo stretch during traffic rush hours.

The connection between downtown Porto Alegre and the highways is made by Avenida Presidente Castelo Branco (President Castelo Branco Avenue), which is a short - 4 kilometres (2.5 mi) - avenue also bordering the northwest side of the city, Avenida dos Estados (States' Avenue), which is the access way to the Salgado Filho International Airport, and Avenida Assis Brasil (Assis Brasil Avenue), the main Avenue in the northern Porto Alegre.

Bus Station in Porto Alegre

Porto Alegre bus service

The city has a functioning transportation system, especially the autobuses. Porto Alegre has also mini-buses from and to all the main neighborhoods in the city, with sitting-only transport and the possibility to hop on and off at any point but also higher fares. Linha Turística (Tourist Line) is a bus that leaves from Usina do Gasômetro tourist terminal around six times per day. During 90 minutes, it traverses the various districts of Porto Alegre, for a modest price.[121] Exclusive bus lanes in the median of seven radial corridors that converge on the city center are used by both urban and regional lines. The bus fleet totals 1,600, with 150 minibuses. About 325 million people use the system annually.[122]

Those lines have no prefix. It is quite common to switch buses at downtown but since there is a myriad of lines there, it can be challenging to find the right terminal for the next bus. Transversal lines prefix "T" (T1, T2, ..., T11), connect different neighborhoods without going through the downtown area, which effectively eliminates the need of changing buses for the most common trips. Circular lines prefix "C" (C1, C2, C3), as the name indicates, run in a circular manner, usually connecting parts of the downtown area to the nearest neighborhoods.[123]

Mayor José Fogaça renewed his agreement with EMBARQ and the Center for Sustainable Transport Brazil (CTS-Brasil) to improve accessibility and mobility in downtown Porto Alegre. The agreement, signed on March 11, includes a new partnership with the Andean Development Corporation, a Latin American multilateral financial institution that is expected to provide $1 million in non-reimbursable technical assistance to help Porto Alegre complete the preparation phase of the "Portais da Cidade" bus rapid transit project, a groundbreaking transport system designed to reduce pollution and congestion downtown. The system will include a southern extension to accommodate activities for the 2014 FIFA World Cup. CAF's technical assistance will be administered through CTS-Brasil, which has been working to expand sustainable transport in Porto Alegre since 2005.[124]

The bus station downtown and is served by several national and international lines. It is also connected to a Trensurb station (Porto Alegre Metro) and several municipal bus lines. Northbound passengers can rely on good bus connections throughout Brazil. However, an express bus might be recommended to travel to Uruguay or Argentina to avoid several stops en route.[125]

Porto Alegre has a total of 3,922 authorized taxicabs, with 317 taxi stops.[126] Regular taxis are colored red, whereas airport taxicabs are colored white, both with blue strips on the sides containing white lettering.

Porto Alegre is twinned with:[132]

Porto Alegre also has the following partner city:
