Lourenço Anes
Lourenço is a town and district in the Brazilian municipality of Calçoene, in the interior of the state of Amapá. The main economic activities of the town is gold mining. It is one of the oldest mines in Brazil. History Gold mining in Lourenço began in the 19th century. In 1894, at the height of the gold rush, there were 6,000 to 10,000 gold miners in the area around the Calçoene River. In 1984, Mineração Novo Astro (MNA) and Mineração Yukio Yoshidome (MYYSA) were awarded concessions for mining on an industrial scale. This resulted in conflicts with the ''garimpeiros'' (illegal gold prospectors). In 1992, the Mining Cooperative of Garimpeiros of Lourenço (COOGAL) was founded, and the concessions were transferred to COOGAL in 1994. As of 2014, COOGAL operates five mining concessions and employs 1,100 ''garimpeiros''. The official census figures for the district are an underestimation, and the actual population is estimated at 4,500 people. Lourenço is located in an are ...

Regions Of Brazil
Brazil is geopolitics, geopolitically divided into five regions (also called macroregions), by the Brazilian Institute of Geography and Statistics, which are formed by the federative units of Brazil. Although officially recognized, the division is merely academic, considering geographic, social and economic factors, among others, and has no political effects other than orientating Federal-level government programs. Under the state level, they are further divided into Intermediate and Immediate Geographic Regions, intermediate regions and even further into microregions of Brazil, immediate regions. The five regions Central-West Region *Area: 1,612,007.2 km2 (18.86%) *Population: 16,289,538 (7.2 people/km2; 6.4%) *GDP: Brazilian real, R$279 billion / United States dollar, US$174,3 billion (2008; 8.3%) (Economy of Brazil, 4th) *Climate: Savanna climate (hot, with little precipitation during winter in the northeast and the east; Tropical in the east and in the west; Equ ...

Garimpeiros
Artisanal and small-scale mining (ASM) is a blanket term for a type of subsistence mining involving a miner who may or may not be officially employed by a mining company but works independently, mining minerals using their own resources, usually by hand. While the terms are generally used interchangeably or synonymously, by definition ‘artisanal mining’ refers to purely manual labor while ‘small-scale mining’ typically involves larger operations and some use of mechanical or industrial tools. While there is no completely coherent definition for ASM, artisanal mining generally includes miners who are not officially employed by a mining company and use their own resources to mine. As such, they are part of an informal economy. ASM also includes, in small-scale mining, enterprises or individuals that employ workers for mining, but who generally still use similar manually-intensive methods as artisanal miners (such as working with hand tools). In addition, ASM can be characte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BR-156
BR-156 is a federal highway of Brazil. The road consists of 552 km between Oiapoque and Macapá, and 271 km between Macapá and Laranjal do Jari (except via Santana city), totalling 823 km of road through forest and savannah. Only the road between Macapá and Calçoene is paved with asphalt. The rest of the road has a dirt surface. Because of the road conditions, it takes around 10-12 hours to drive between Oiapoque and Macapá. With the Oyapock River Bridge (linking the cities of Oiapoque in Brazil and Saint-Georges-de-l'Oyapock in French Guiana) open to traffic starting from 20 March 2017, it is now possible to drive from Macapá to Cayenne, the capital city of French Guiana French Guiana, or Guyane in French, is an Overseas departments and regions of France, overseas department and region of France located on the northern coast of South America in the Guianas and the West Indies.

Deforestation
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. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. 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 ...

Mercury (element)
Mercury is a chemical element; it has Symbol (chemistry), symbol Hg and atomic number 80. It is commonly known as quicksilver. A Heavy metal element, heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Exposure to mercury and mercury-containing organic compounds is toxic to the nervous system, immune system and kidneys of humans and other animals; mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury) either directly or through mechanisms of biomagnification. Mercu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Territory (Brazil)

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; this ...

Landslide Gold Mine Lourenço Amapá Brazil
Landslides, also known as landslips, rockslips or rockslides, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Landslides are frequently made worse by human development (such as urban sprawl) and resource exploitation (such as mining and deforestation). Land degradation freque ...

Gold Mining
Gold mining is the extraction of gold by mining. Historically, mining gold from Alluvium, alluvial deposits used manual separation processes, such as gold panning. The expansion of gold mining to ores that are not on the surface has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations. However, the value of gold has led to millions of small, Artisanal mining, artisanal miners in many parts of the Global South. Like all mining, Mining#Human rights, human rights and Environmental effects of mining, environmental issues are common in the gold mining industry, and can result in environmental conflict. In mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
