Northeast Region, Brazil
The Northeast Region of Brazil (Portuguese: Região Nordeste do Brasil [ʁeʒiˈɐ̃w nɔʁˈdɛstʃi du bɾaˈziw]) is one of the five official and political regions of the country according to the Brazilian Institute of Geography and Statistics. Of Brazil's twenty-six states, it comprises nine: Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe and Bahia, along with the Fernando de Noronha archipelago (formerly a separate territory, now part of Pernambuco).
Not to be confused with the Nordeste municipality in the Azores archipelago. For the socio-geographic area of Brazil, see Nordeste (socio-geographic division).
Chiefly known as Nordeste ("Northeast") in Brazil, this region was the first to be colonized by the Portuguese and other European peoples, playing a crucial role in the country's history. Nordeste's dialects and rich culture, including its folklore, cuisines, music and literature, became the most easily distinguishable across the country. To this day, Nordeste is known for its history and culture, as well as for its natural environment and its hot weather.
Nordeste stretches from the Atlantic seaboard in the northeast and southeast, northwest and west to the Amazon Basin and south through the Espinhaço highlands in southern Bahia. It encloses the São Francisco River and drainage basin, which were instrumental in the exploration, settlement and economic development of the region. The region lies entirely within the earth's tropical zone and encompasses Caatinga, Atlantic Forest and part of the Cerrado ecoregions. The climate is hot and semi-arid, varying from xeric in Caatinga, to mesic in Cerrado and hydric in the Atlantic Forest.
The Northeast Region represents 18% of Brazilian territory, has a population of 57 million people, 28% of the total population of the country, and contributes 14.2% (2020) of Brazil's GDP.[2] Nearly three quarters of the population live in urban areas clustered along the Atlantic coast and about 15 million people live in the hinterland. It is an impoverished region: 43.5% of the population lives in poverty, defined as less than $2/day.[3]
The capital of each state is also its largest city. These include Salvador, Recife, Fortaleza and São Luís, all of which are coastal cities with a population above one million.[4] Nordeste has nine international airports,[Note 1] and the region has the second largest number of passengers (roughly 20%) in Brazil.
Geology and topography[edit]
Geographically, Nordeste consists chiefly of an eroded continental craton with many low hills and small ranges. The highest peaks are around 1,850 metres (6,070 ft) in Bahia, while further north there are no peaks above 1,123 metres (3,684 ft). On its northern and western side, the plateaus fall steadily to the coast and into the basin of the Tocantins River in Maranhão, but on the eastern side it falls off quite sharply to the coast except in the valley of the São Francisco river. The steep slopes and long cliffs of the eastern coastline are known as "The Great Escarpment".
The escarpment serves an extremely important climatic function. Because for most of the year Nordeste is out of reach of the Intertropical Convergence Zone, the easterly trade winds blow across the region, giving abundant rainfall to the coast but producing clear, dry conditions inland where the escarpment blocks moisture flow. This gives rise to four distinct regions, the zona da mata on the coast, the agreste on the escarpment, sertão beyond and the Mid north.
