Amazônia Legal
Amazônia Legal (), also known as Brazil's Legal Amazon (BLA), is the largest socio-geographic division in Brazil, containing all nine states in the Amazon basin. The government designated this region in 1948 based on its studies on how to plan the economic and social development of the Amazon region. Area The official designation Amazônia Legal encompasses all seven states of the North Region (Acre, Amapá, Amazonas, Pará, Rondônia, Roraima and Tocantins), as well as most of Mato Grosso in the Center-West Region and the western part of Maranhão in the Northeast Region. Amazônia Legal is a 5,016,136.3 km2 region with around 24 million inhabitants; in other words 59% of the geographic territory of Brazil is part of Amazônia Legal, but only 12.34% of the Brazilian population lives there. The administrative unit was initially established by Federal Law No. 5.173 (Art. 2). Although called ''Amazônia Legal,'' the region overlaps three different biomes: all of Brazil's ...

Amazon Biome
The Amazon biome ( pt, Bioma Amazônia) contains the Amazon rainforest, an area of tropical rainforest, and other ecoregions that cover most of the Amazon basin and some adjacent areas to the north and east. The biome contains blackwater and whitewater flooded forest, lowland and montane terra firma forest, bamboo and palm forest, savanna, sandy heath and alpine tundra. Some areas are threatened by deforestation for timber and to make way for pasture or soybean plantations. Location The Amazon biome has an area of . The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin. J. J. Morrone (2006) defines the Amazonian subregion in this broader sense, divided into the biogeographical provinces of Guyana, Humid Guyana, Napo, Imeri, Roraima, Amapá, Várzea, Ucayali, Madeira, Tapajós-Xingu, Pará, Yun ...

Deforestation In Brazil
Brazil once had the highest deforestation rate in the world and in 2005 still had the largest area of forest removed annually. Since 1970, over of the Amazon rainforest have been destroyed. In 2001, the Amazon was approximately , which is only 87% of the Amazon's original size. According to official data, about 729,000 km² have already been deforested in the Amazon biome, which corresponds to 17% of the total. 300,000 km2 have been deforested in the last 20 years. Rainforests have decreased in size primarily due to deforestation. Between May 2000 and August 2006, Brazil lost nearly of forest, an area larger than Greece. According to the Living Planet Report 2010, deforestation continues at an alarming rate. At the Convention on Biological Diversity's 9th Conference, 67 ministers signed up to help achieve zero net deforestation by 2020. Due to deforestation the Amazon was a net emitter of greenhouse gas in the 2010s. History The deforestation of the Atlantic forest, or ''Ma ...

Nordeste (socio-geographic Division)
The socio-geographic division of Nordeste (, ''Northeast'') is the oldest populated by Europeans (also with the oldest fossils that suggests human presence in Brazil) and currently the second most populous area of Brazil (42,822,100 in 1990). Area Its area is approximately 1,542,271 km², made up of the official Northeast Region, minus the western half of Maranhão, but including the north of Minas Gerais - the Jequitinhonha Valley. A major part of its territory is made of an extensive plateau, old and flattened by erosion. Due to different physical characteristics, the region can be divided into four sub-regions: meio-norte, zona da mata, agreste and sertão. In the Socio-Geographic division of Brazil, parts of meio-norte are considered Amazônia Legal and not Nordeste. Demographics Northeast Brazilians are a result of the mixing of Europeans, Africans and Native Americans. The African ancestry is significant particularly in the coastal areas. Especially in the ...

Centro-Sul
Centro-Sul (, ''South-Central'') is a geographic area that encompasses the Southeastern, Southern and Central-West regions of Brazil (see Brazil Regional Division), excluding the north of Minas Gerais and most of Mato Grosso as well as parts of Tocantins. Demographics In this region live around 135 million Brazilians. The most remarkable characteristics of the region is the human domination over the nature: only ~5% of the native vegetation is left. Other very strong characteristic is populational and economic: most industries are concentrated in the area and responsible for ~75% of the national GDP. The vast majority of the population (+90%) is of mostly European ancestry, and more than half of the population self-identify as White Brazilian. The region also is characterized by having a high standard of living (HDI of ~0.787, in average), where social problems are less problematic than in other regions (at least, in rural and small-medium-sized cities). It is not difficult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazilian Institute Of Environment And Renewable Natural Resources
Brazilian Institute of the Environment and Renewable Natural Resources ( pt, Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis, IBAMA) is the Brazilian Ministry of the Environment's administrative arm. IBAMA supports anti-deforestation of the Amazon, and implements laws against deforestation where the government ceases to implement. IBAMA works to keep the forest from loggers, farming, agricultural farm grazing and anything that would threaten the Amazon. Spix's macaw Among IBAMA's diverse environmental and natural resources activities, it manages The Working Group for the Recovery of the Spix's macaw and the associated ''Ararinha Azul'' project for conserving one of the rarest birds in the world. However the last Spix's macaw living in the wilderness disappeared in 2000 and the species became extinct in the wild. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Density
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. In simple terms, population density refers to the number of people living in an area per square kilometre, or other unit of land area. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usuall ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Extractive Reserve (Brazil)
An extractive reserve ( pt, Reserva Extrativista or RESEX) is a type of sustainable use protected area in Brazil. The land is publicly owned, but the people who live there have the right to traditional extractive practices, such as hunting, fishing and harvesting wild plants. Definition In the broad sense, an extractive reserve is an area of land, generally state State may refer to: Arts, entertainment, and media Literature * ''State Magazine'', a monthly magazine published by the U.S. Department of State * ''The State'' (newspaper), a daily newspaper in Columbia, South Carolina, United States * ''Our S ...-owned where access and use rights, including natural resource extraction, are allocated to local groups or communities. Extractive reserves limit deforestation both by the local residents, preventing deforestation within their reserve, and by acting as a buffer zone to keep ranching and extractive industry out of the forests beyond.

Indigenous Peoples In South America
The Indigenous peoples of South America or South American Indigenous peoples, are the pre-Colombian peoples of South America and their descendants. These peoples contrast with South Americans of European ancestry and those of African descent. In Spanish, Indigenous people are often referred to as ''indígenas'' or ''pueblos indígenas'' (lit. Indigenous peoples). They may also be called ''pueblos nativos'' or ''nativos'' (lit. Native peoples). The term ''aborigen'' (lit. aborigine) is used in Argentina and ''pueblos aborígenes'' (lit. aboriginal peoples) is commonly used in Colombia. The English term "Amerindian" (short for "Indians of the Americas") is often used in the Guianas. Latin Americans of mixed European and Indigenous descent are usually referred to as mestizos (Spanish) and mestiços (Portuguese). While those of mixed African and Indigenous ancestry are referred to as zambos. It is believed that the first human populations of South America either arrived from Asia ...

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

Vegetation
Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term ''flora'' which refers to species composition. Perhaps the closest synonym is plant community, but ''vegetation'' can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term ''vegetation''. The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality. The contemporary use of ''vegetation'' approximates that of ecologist Frederic Clements' term earth cover, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
