“…Fertile in natural resources, Angola is an oil and gas production dependent economy from which related activities account for 85% of its GDP (Silva, Roque, & Caetano, 2015). Angola is located on the west coast of southern Africa with an area of 1,246.700 km 2 that was discovered by the Portuguese explorers in 1482, becoming then a trade link with Southeast Asia and India and later a major source of slave trade for Portugal's colonies in Brazil and Caribbean (Nakabashi et al, 2013;Ojo, 2015;Silva et al, 2015). With the end of the slave trade by 1878 (Ball, 2017), an uprising between Angolan national liberation movements in 1950 led to a civil war conflict that lasted 27 years, which culminated to Angola's independence in 1975 and the end of the armed conflict by 2002 (Baumgartner, 2016a;Silva et al, 2015).…”
