Beni, sometimes El Beni, is a northeastern department of Bolivia, in the lowlands region of the country. It is the second-largest department in the country, covering 213,564 square kilometers, and it was created by supreme decree on November 18, 1842, during the administration of General José Ballivián. Its capital is Trinidad.
In archaeology, a ring ditch is a trench of circular or penannular plan, cut into bedrock. They are usually identified through aerial photography either as soil marks or cropmarks. When excavated, ring ditches are usually found to be the ploughed‐out remains of a round barrow where the barrow mound has completely disappeared, leaving only the infilled former quarry ditch. Both Neolithic and Bronze Age ring ditches have been discovered.
The Mamoré is a large river in Brazil and Bolivia which unites with the Madre de Dios River to form the Madeira, one of the largest tributaries of the Amazon. It rises on the northern slope of the Sierra de Cochabamba, east of the city of Cochabamba, and is known as the Chimoré down to its junction with the Chapare. Its larger tributaries are the Chapare, Secure, Apere, and Yacuma from the west, and the Ichilo, Guapay, Ivari, Manique and Guapore from the east. Taking into account its length only, the Guapay should be considered the upper part of the Mamore; but it is shallow and obstructed, and carries a much smaller volume of water. The Guapore also rivals the Mamore in length and volume, having its source in the Parecis plateau, Mato Grosso, Brazil, a few miles from streams flowing north-ward to the Tapajos and Amazon, and southward to the Paraguay and Paraná rivers. The Mamore is interrupted by rapids a few miles above its junction with the Beni, but a railway 300 km long has been undertaken from below the rapids of the Madeira. Above the rapids the river is navigable to Chimore, at the foot of the sierra, and most of its tributaries are navigable for long distances. In 1874, Franz Keller gave the outflow of the Mamoré at mean water level, and not including the Guapore, as 41,459 cm3/sec, and the area of its drainage basin, also not including the Guapore, as 24,299 km2.
Trinidad, officially La Santísima Trinidad, is a city in Bolivia, capital of the department of Beni. The population is 130,000. While historically a peripheral city in Bolivia, Trinidad is today an important center for the Bolivian Bovine industry and has enjoyed a modest economic boom in recent years and has an HDI index of above 0.700.
A fishing weir, fish weir, fishgarth or kiddle is an obstruction placed in tidal waters, or wholly or partially across a river, to direct the passage of, or trap fish. A weir may be used to trap marine fish in the intertidal zone as the tide recedes, fish such as salmon as they attempt to swim upstream to breed in a river, or eels as they migrate downstream. Alternatively, fish weirs can be used to channel fish to a particular location, such as to a fish ladder. Weirs were traditionally built from wood or stones. The use of fishing weirs as fish traps probably dates back prior to the emergence of modern humans, and have since been used by many societies around the world.
Bauré is an endangered Arawakan language spoken by only 40 of the thousand Baure people of the Beni Department of northwest of Magdalena, Bolivia. Some Bible portions have been translated into Bauré. Most speakers have been shifting to Spanish.
The Marajoara or Marajó culture was an ancient pre-Columbian era culture that flourished on Marajó island at the mouth of the Amazon River in northern Brazil. In a survey, Charles C. Mann suggests the culture appeared to flourish between 800 AD and 1400 AD, based on archeological studies. Researchers have documented that there was human activity at these sites as early as 1000 BC. The culture seems to have persisted into the colonial era.
In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks can themselves be archaeological features, or they can show features beneath the surface.
The Llanos de Moxos, also known as the Beni savanna or Moxos plains, is a tropical savanna ecoregion of the Beni Department of northern Bolivia.
The Mojeños, also known as Moxeños, Moxos, or Mojos, are an indigenous people of Bolivia. They live in south central Beni Department, on both banks of the Mamore River, and on the marshy plains to its west, known as the Llanos de Mojos. The Mamore is a tributary to the Madeira River in northern Bolivia.
Waru Waru is an Aymara term for the agricultural technique developed by pre-Hispanic people in the Andes region of South America from Ecuador to Bolivia; this regional agricultural technique is also referred to as camellones in Spanish. Functionally similar agricultural techniques have been developed in other parts of the world, all of which fall under the broad category of raised field agriculture.
Moxo is any of the Arawakan languages spoken by the Moxo people of the Llanos de Moxos in northeastern Bolivia. The two extant languages of the Moxo people, Trinitario and Ignaciano, are as distinct from one another as they are from neighboring Arawakan languages. The extinct Magiana was also distinct.
San Joaquín is a small agricultural town in the Beni Department in the Bolivian lowlands.
William Maxfield Denevan is an American geographer. He is professor emeritus of Geography at the University of Wisconsin-Madison and is a prominent member of the Berkeley School of cultural-historical geography. He also worked in the Latin American Center and the Institute for Environmental Studies at Wisconsin. His research interests are in the historical ecology of the Americas, especially Amazonia and the Andes.
In agriculture, a raised field is a large, cultivated elevation, typically bounded by water-filled ditches, that is used to allow cultivators to control environmental factors such as moisture levels, frost damage, and flooding. Examples of raised field agriculture can be found among some Pre-Hispanic cultures of Latin America, such as those from tropical lowlands and the Budi Lake Mapuche.
The Jesuit Missions of Moxos are located in the Llanos de Moxos of Beni department in eastern Bolivia. Distinguished by a unique fusion of European and Amerindian cultural influences, the missions were founded as reductions or reducciones de indios by Jesuits in the 17th and 18th centuries to convert local tribes to Christianity.
The Mamoré–Guaporé linguistic area is a linguistic area that includes over a dozen South American language families and isolates of the Mamoré–Guaporé region of eastern lowland Bolivia and Brazil.
Forest islands are atypical isolated stands of tropical forest on the Amazonian savanna. Their origin is largely unknown. One hypothesis suggests anthropomorphic origins, those forest islands being earlier human farming of diverse useful, food-producing tropical plants and trees, collected and willfully inserted in suitable points of the grassland.
Pre-Columbian agriculture in the Amazon basin refers to the farming practices developed by the indigenous communities of the Amazon rainforest before the European conquest. Contrary to the common misconception of the pre-Columbian rainforest as a pristine wilderness untouched by human influence, agricultural communities in the Amazon Basin actively shaped and managed their environment prior to the arrival of European colonists. Eyewitness accounts by early Spanish and Portuguese explorers describe populous cities and flourishing agriculture. Population estimates for the pre-Columbian Amazon Basin range from a few million people to up to 10 million. After the population collapse following the European conquest, these communities were largely forgotten. Recent scientific research has helped to reconstruct the story of these lost settlements.
The Upano Valley sites are a cluster of archaeological sites in the Amazon rainforest. They are located in the Upano River valley in Morona-Santiago Province in eastern Ecuador. The sites comprise several cities; they are believed to have been inhabited as early as 500 BC, predating any other known complex Amazonian society by over a millennium.
