The Amazon rainforest, also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km2 (2,700,000 sq mi), of which 6,000,000 km2 (2,300,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations and 3,344 indigenous territories.
Rainforests are forests characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described.
Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10° north and south of the Equator. They are a subset of the tropical forest biome that occurs roughly within the 28° latitudes. Tropical rainforests are a type of tropical moist broadleaf forest, that includes the more extensive seasonal tropical forests. True rainforests usually occur in tropical rainforest climates where no dry season occurs; all months have an average precipitation of at least 60 mm (2.4 in). Seasonal tropical forests with tropical monsoon or savanna climates are sometimes included in the broader definition.
Shorea is a genus of about 196 species of mainly rainforest trees in the family Dipterocarpaceae. The genus is named after Sir John Shore, the governor-general of the British East India Company, 1793–1798. The timber of trees of the genus is sold under the common names lauan, luan, lawaan, meranti, seraya, balau, bangkirai, and Philippine mahogany.
The Machiguenga are an indigenous people who live in the high jungle, or montaña, area on the eastern slopes of the Andes and in the Amazon Basin jungle regions of southeastern Peru. Their population in 2020 amounted to about 18,000. Formerly they were hunter-gatherer but today the majority are sedentary swidden cultivators. The main crops grown are manioc, maize, and bananas, but today commercial crops such as coffee and cacao are increasingly important. Their main source of protein used to be peccary and monkeys but today fish has become more important as game animals have become increasingly scarce as a consequence of the encroachment from highland immigrants to the area and the exploitation of the Camisea gas finds. The Machiguenga people have a preference for self-sufficiency when it comes to cultivating essential crops, made possible by their generous land allocation per capita, and the lack of conflict in their area.
Andrew P. "Pete" Vayda was a Hungarian-born American anthropologist and ecologist who was a distinguished professor emeritus of anthropology and ecology at Rutgers University.
Darrell Addison Posey was an American anthropologist and biologist who vitalized the study of traditional knowledge of indigenous and folk populations in Brazil and other countries. He called his approach ethnobiology and combined research with respect for other cultures, especially indigenous intellectual property rights.
The scaled spinetail is a species of bird in the family Furnariidae. It is endemic to the lower Amazon River in Brazil, where it inhabits várzea forests and tropical or subtropical swamplands.
Anna Curtenius Roosevelt is an American archaeologist and Distinguished Professor of Anthropology at the University of Illinois Chicago. She studies human evolution and long-term human-environment interaction. She is one of the leading American archeologists studying Paleoindians in the Amazon basin. Her field research has included significant findings at Marajo Island and Caverna da Pedra Pintada in Brazil. She does additional field work in the Congo Basin. She is the great-granddaughter of United States President Theodore Roosevelt.

Deforestation is a primary contributor to climate change, and climate change affects the health of forests. Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon. Global models and national greenhouse gas inventories give similar results for deforestation emissions. As of 2019, deforestation is responsible for about 11% of global greenhouse gas emissions. Carbon emissions from tropical deforestation are accelerating.

Road expansion refers to the increasing rate at which roads are constructed globally. Increases in population size and GDP, particularly in developing nations, are the primary drivers of road expansion but transportation planning decisions also play an important role. The anticipated length of newly paved roads to be built between 2010 and 2050 would encircle the planet more than 600 times. Approximately 90% of the new roads are being built in developing nations. Africa and Southeast Asia are predicted to experience a large amount of road expansion shortly.
Britaldo Silveira Soares Filho is a Brazilian scientist, and Professor in Environment Modeling at Universidade Federal de Minas Gerais. Britaldo is one of winners of the Georg Foster Research Awards because "he has developed innovative methods in the field of geography and cartography which make it possible to precisely predict how tropical rainforests – such as in the Amazon basin – will develop. Based on these models, the government of Brazil has implemented a variety of protective measures and is planning more for the future."
Jennifer K. Balch is an American scientist best known for her work involving the Earth Lab Project at University of Colorado Boulder, primarily researches the relationship between fire and the Amazon. She specializes in research involving temperate and tropical ecosystems.
Carlos Afonso Nobre is a Brazilian scientist and meteorologist who is mainly highlighted in global warming-related studies. Nobre spearheaded the multi-disciplinary, multinational Large-Scale Biosphere-Atmosphere Experiment in Amazonia, a program noted to have “revolutionized understanding of the Amazon rainforest and its role in the Earth system.”
Elaeocarpus griffithii is a tree in the family Elaeocarpaceae. It is found in parts of Island and Mainland Southeast Asia. It is used in construction, as firewood and in dyeing.
