Lourenço Castanho Taques
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 ...

Regions Of Brazil
Brazil is 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, there are also mesoregions and microregions. The five regions North Region *Area: 3,689,637.9 km2 (45.27%) *Population: 17,707,783 (4,6 people/km2; 6.2%; 2016) *GDP: R$ 308 billion / US$94,8 billion (2016; 4.7%) ( 5th) *Climate: Equatorial *States: Acre, Amapá, Amazonas, Pará, Rondônia, Roraima, Tocantins *Largest Cities: Manaus (2,094,391); Belém (1,446,042); Porto Velho (511,219); Ananindeua (510,834); Macapá (465,495); Rio Branco (377,057); Boa Vista (326,419); Santarém (294,447); Palmas (279 856). *Economy: Iron, Copper, ...

Garimpeiros
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with 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 miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller 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 built between 4700 and 4200 BC, indicating that gold mining could be at least 700 ... [...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 ; french: link=no, Guyane ; gcr, label=French Guianese Creole, Lagwiyann ) is an overseas departments and regions of France, overseas department/region and single territorial collectivity of France on the northern Atlantic ....

Deforestation
Deforestation or forest clearance is the removal 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. The most concentrated deforestation occurs in tropical rainforests. 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, a 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. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Indigenous Territory (Brazil)
In Brazil, an indigenous territory or indigenous land ( pt, Terra Indígena , TI) is an area inhabited and exclusively possessed by indigenous people. Article 231 of the Brazilian Constitution recognises the inalienable right of indigenous peoples to lands they "traditionally occupy"Defined as those lands "on which they live on a permanent basis, those used for their productive activities, those indispensable to the preservation of the environmental resources necessary for their well-being and for their physical and cultural reproduction, according to their uses, customs and traditions."Federal Constitution of BrazilChapter VII Article 231. and automatically confers them permanent possession of these lands. In practice, however, a multi-stage demarcation process is required for a TI to gain full protection, and this has often entailed protracted legal battles. Even after demarcation, TIs are frequently subject to illegal invasions by settlers and mining and logging companies. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the enabling laws of each country or the regulations of the international organizations involved. Generally speaking though, protected areas are understood to be those in which human presence or at least the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas, the boundaries of which will include some area of ocean, and transboundary protected areas that overlap multiple countries which remove the borders inside the area for conservation and economic purposes. There are over 161,000 protected areas in the world (as of October 2010) with more added daily, representing between 10 and 15 percent of the world's land surface area. As of 20 ...

Landslide Gold Mine Lourenço Amapá Brazil
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, 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 a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
