Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.

The direct cause of most deforestation is agriculture by far. More than 80% of deforestation was attributed to agriculture in 2012. Forests are being converted to plantations for coffee, palm oil, rubber and various other popular products. Livestock grazing also drives deforestation. Further drivers are the wood industry (logging), urbanization and mining. The effects of climate change are another cause via the increased risk of wildfires (see deforestation and climate change).

The Cerrado (Portuguese pronunciation: [seˈʁadu]) is a vast ecoregion of tropical savanna in central Brazil, being present in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Maranhão, Piauí, Bahia, Minas Gerais, São Paulo, Paraná and the Federal District. The core areas of the Cerrado biome are the Brazilian highlands – the Planalto. The main habitat types of the Cerrado consist of forest savanna, wooded savanna, park savanna and gramineous-woody savanna. The Cerrado also includes savanna wetlands and gallery forests.

The second largest of Brazil's major habitat types, after the Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia). About 75% of the Cerrado’s 2 million km is privately owned.

The Amazon rainforest, spanning an area of 3,000,000 km (1,200,000 sq mi), is the world's largest rainforest. It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests. The Amazon region includes the territories of nine nations, with Brazil containing the majority (60%), followed by Peru (13%), Colombia (10%), and smaller portions in Venezuela, Ecuador, Bolivia (6%), Guyana, Suriname, and French Guiana. Over one-third of the Amazon rainforest is designated as formally acknowledged indigenous territory, amounting to more than 3,344 territories. Historically, indigenous Amazonian peoples have relied on the forest for various needs such as food, shelter, water, fiber, futon, and medicines. The forest holds significant cultural and cosmological importance for them.

Despite external pressures, deforestation rates are comparatively lower in indigenous territories due to legal land titling initiatives that have reduced deforestation by 75% in Peru. By the year 2022, around 26% of the forest was considered as deforested or highly degraded. According to the Council on Foreign Relations, 300,000 square miles have been lost.

The Brazilian War of Independence (Portuguese: Guerra de Independência do Brasil) was an armed conflict that led to the separation of Brazil from the United Kingdom of Portugal, Brazil and the Algarves. The war was fought across various regions of Brazil, including Bahia, Maranhão, Pará, Piauí, and Cisplatina (present-day Uruguay), with naval battles occurring along the Atlantic coast. Brazilian forces, consisting of regular troops, local militias, and a hastily assembled fleet, defeated the Portuguese garrisons to establish the Empire of Brazil under emperor Pedro I. The war formally ended with the Treaty of Rio de Janeiro in 1825, in which Portugal recognized Brazil's independence.

After the outbreak of the Liberal Revolution in 1820, which forced king John VI to return to Portugal in 1821 after more than a decade in Rio de Janeiro, tensions between local Brazilian elites and the Portuguese Cortes arose. During his stay in Brazil, John VI had elevated the colony to the status of a kingdom in union with Portugal. The changes allowed Brazil to have its own government institutions and directly trade with the rest of the world, which many elites sought to preserve. Efforts by the Portuguese Cortes to restore Brazil to its former colonial status and reduce its political autonomy were met with resistance in various provinces. The tensions culminated in prince regent Pedro of Braganza's proclamation of independence on 7 September 1822, in what became known as the Cry of Ipiranga. Northern provinces, such as Bahia, Maranhão, and Pará, which maintained stronger ties with Portugal than the government in Rio de Janeiro, resisted Brazilian sovereignty, with Portuguese garrisons keeping control of key cities such as Salvador, São Luís, Belém, and Montevideo, in the South.

The Tocantins River (Portuguese: Rio Tocantins Portuguese pronunciation: [ˈʁi.u tokɐ̃ˈtʃĩs, tu-], Parkatêjê: Pyti [pɨˈti]) is a river in Brazil, the central fluvial artery of the country. In the Tupi language, its name means "toucan's beak" (Tukã for "toucan" and Ti for "beak"). It runs from south to north for about 2,450 km (1,520 mi). While sometimes included in definitions of the Amazon basin, the Tocantins is not a branch of the Amazon River, since its waters flow into the Atlantic Ocean via an eastern channel of the Amazon Delta, alongside those of the Amazon proper. It flows through four Brazilian states (Goiás, Tocantins, Maranhão, and Pará) and gives its name to one of Brazil's newest states, formed in 1988 from what was until then the northern portion of Goiás.

The Tocantins is one of the largest clearwater rivers in South America.

Pará (Brazilian Portuguese: [paˈɾa] ) is a state of Brazil, located in northern Brazil and traversed by the lower Amazon River. It borders the Brazilian states of Amapá, Maranhão, Tocantins, Mato Grosso, Amazonas and Roraima. To the northwest are the borders of Guyana and Suriname, to the northeast of Pará is the Atlantic Ocean. The capital and largest city is Belém, which is located at the Marajó bay, near the estuary of the Amazon river. The state, which is home to 4.1% of the Brazilian population, is responsible for just 2.2% of the Brazilian GDP.

Pará is the most populous state of the North Region, with a population of over 8.6 million, being the ninth-most populous state in Brazil. It is the second-largest state of Brazil in area, at 1.2 million square kilometres (460,000 sq mi), second only to Amazonas upriver. Its most famous icons are the Amazon River and the Amazon rainforest. Pará produces rubber (extracted from rubber tree groves), cassava, açaí, pineapple, cocoa, black pepper, coconut, banana, tropical hardwoods such as mahogany, and minerals such as iron ore and bauxite. A new commodity crop is soy, cultivated in the region of Santarém.

Teresina is the capital and most populous municipality in the Brazilian state of Piauí. Being located in north-central Piauí 366 km from the coast, it is the only capital in the Brazilian Northeast that is not located on the shores of the Atlantic Ocean. With 902,644 inhabitants, Teresina is the 19th largest city in Brazil, and the 16th largest state capital in the country. Together with Timon in the neighbouring state of Maranhão, it forms a conurbation with a population of about 2,729,527 inhabitants; the entire metropolitan region of Teresina has over 2,893,729 inhabitants. The only natural barrier that separates Teresina from Timon is the Parnaíba River, one of the largest in the Northeast.

Teresina is the capital with the best quality of life in the North-Northeast according to FIRJAN and the 4th in Brazil. It is among the 50 cities in the world with the highest murder rates, with 315 homicides in 2017.
