Chacorão Dam
The Chacorão Dam (or Chocorão Dam, pt, Barragem de Chacorão) is a proposed dam on the Tapajós river in the state of Pará, Brazil. It would flood a section of rapids in the river, making them navigable by barges carrying soybeans to ports on the Amazon River. The dam would include locks for the barges and a hydroelectric power plant. It is controversial since it would flood a large area of an indigenous territory. Location The proposed Chacorão Dam would be built on the Tapajós river in the state of Pará. The hydroelectric power plant would be part of the proposed Tapajós hydroelectric complex on the Tapajos and Jamanxim rivers. Others are the São Luiz do Tapajós (6,133 MW), Jatobá (2,338 MW), Cachoeira dos Patos (528 MW), Jamanxim (881 MW) and Cachoeira do Cai (802 MW) plants, all under study, as well as the less advanced proposal for the Jardim do Ouro (227 MW).

Tapajós
The Tapajós ( pt, Rio Tapajós ) is a river in Brazil. It runs through the Amazon Rainforest and is a major tributary of the Amazon River. When combined with the Juruena River, the Tapajós is approximately long. It is one of the largest clearwater rivers, accounting for about 6% of the water in the Amazon basin. Course For most of its length the Tapajós runs through Pará State, but the upper (southern) part forms the border between Pará and Amazonas State. The source is at the Juruena–Teles Pires river junction. The Tapajós River basin accounts for 6% of the water in the Amazon Basin, making it the fifth largest in the system.Hales, J., and P.

Juruena National Park
Juruena National Park ( pt, Parque Nacional do Juruena), declared in 2006, is the third largest national park of Brazil. It is located along the Juruena River, in the north of Mato Grosso state and the south of Amazonas state.

The largest is that of the São To ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Pará
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Stations In Brazil
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Sai Cinza Indigenous Territory
The Sai Cinza Indigenous Territory ( pt, Terra Indígena Sai Cinza) is an indigenous territory in the state of Pará, Brazil.

Apiacá
The Apiacá, or Apiaká, are an indigenous people of Brazil, who live in northern Mato Grosso, near the border of Pará. They speak an Apiacá language that is a subgroup part of the Tupi-Guarani languages, though many today speak Portuguese. Prior to the 19th century, the Apiacá were a warlike tribe with a heavily agricultural culture. Around the mid-19th century, their numbers began to decline. This decrease coincided with the contact of European settlers in Brazil. Though thought to be extinct, their numbers, today, are increasing. In 2001, there were only 192 Apiaká. As of 2009, there are a thousand Apiaká people. Language The Apiaká language belongs to subgroup VI of the Tupi-Guarani languages.

Kayabí
The Kayabí or Kaiabi are an indigenous people of Brazil inhabiting the northern state of Mato Grosso. They primarily live in the Xingu Indigenous Park and the Indian Reservation of Apiaká-Kayabi south of Pará. There are approximately 1300 Kayabí living on the Xingu Indigenous Park. They are known by a number of names; Caiabi, Parua, Maquiri, Kawaiwete and many more romanizations of the word Kaiabi. Though residing on a reservation with 14 other indigenous groups, the Kayabi still remained very much heterogeneous. They maintained their traditional way of life, and practiced their customs unchanged for centuries. It was this longing for the preservation of culture and life that mandated the Kayabi left their native lands and seek shelter and protection. During colonial times indigenous peoples had their villages disseminated, raided and even destroyed if located on resource rich lands. Many men were killed and women forced into slavery during these acts of ethnocide. Countles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
