Petrolina is a municipality located in the southernmost point of the state of Pernambuco, in NortheastBrazil, in the valley of the São Francisco River. The population was 354,317 in 2020, and the total area is 4,756.8 km²,[3] making it the largest municipality in the state by area. The municipality is closely integrated with Juazeiro, Bahia, located on the opposite bank of the São Francisco.
Etymology
Formerly called Passagem de Juazeiro (lit.'Passage of Juazeiro'), there is no single story explaining the origin of the name Petrolina. One theory is that the name was in tribute of Brazilian emperor Pedro I and his consort Leopoldina, while another asserts that Petrolina was named for a 'beautiful rock' (Portuguese: Pedra linda) found on the banks of the São Francisco.[4]
History
The growth of Petrolina and its twin city Juazeiro in the late 20th century is the result of the construction of the Sobradinho Dam and the abundant availability of water for irrigation in these otherwise semi-arid soils. The region is perhaps the only one in the interior of the Northeast that has gained population through in-migration. While the population in the states of Pernambuco and Bahia as a whole increased by 50.1% between 1970 and 1990, it more than doubled in Petrolina-Juazeiro.[citation needed]
Starting in the 1960s with the development policies implemented by the government, the valley soon became the beneficiary of important investments for economic development, translated into the construction of highways, increasing electrical energy, improvement in sanitation systems etc.
Investments made in the agricultural sector with the implantation of the irrigated sections of Bebedouro and Senador Nilo Coelho, in turn brought in the installation of factories connected to the regional agriculture base, especially producers of tomato paste, juices, textiles etc.
Agriculture has grown by leaps and bounds with irrigated farming being the main source of income and jobs in Petrolina. The Petrolina-Juazeiro nucleus has turned into a producer of a wide range of irrigated high-value crops, including table grapes and mangos that are sold fresh by cargo aircraft to Europe and the United States, and other crops for the domestic market, including bananas, coconuts, guavas, passion fruit, melons, industrial tomatoes, watermelons and onions, among others. Due to irrigation, growers in Petrolina-Juazeiro produce 90% of the country's exports of mangos and 30% of table grapes, displacing the states of São Paulo and Rio Grande do Sul as the most important exporters of these products.

Petrolina is situated on the left (northern) bank of the São Francisco River, in the interior semi-arid Sertão subregion, at an elevation of 376 m.
On the other side of the river sits Juazeiro, in state of Bahia, and together the cities form an integrated metropolitan area. The two cities, making up an urban area of almost 700,000 people, are connected by the President Dutra Bridge. The Sobradinho Dam is located 26 km up river, and creates the Sobradinho Reservoir, the 34th largest reservoir by volume in the world.[5]
The municipality was designated a priority area for conservation and sustainable use when the Caatinga Ecological Corridor was created in 2006.[6]
