In 1860, Spain occupied northern Morocco and ushered in a half century of trade rivalry among European powers that saw Morocco's sovereignty steadily erode; in 1912, the French imposed a protectorate over the country. A protracted independence struggle with France ended successfully in 1956. Moroccan economic policies brought macroeconomic stability to the country in the early 1990s but have not spurred growth sufficient to reduce unemployment that nears 20% in urban areas. Poverty has increased due to the volatile nature of GDP, Morocco's continued dependence on foreign energy, and its inability to promote the growth of small and medium size enterprises. However, GDP growth rebounded to 6.7% in 2006 due to high rainfall, which resulted in a strong second harvest. According to the African Development Bank, the GDP of Morocco accounts for 7% of the African continent and is the fifth economic power of Africa. Long-term challenges include preparing the economy for freer trade with the US and European Union, improving education and job prospects for Morocco's youth, and raising living standards, which the government hopes to achieve by increasing tourist arrivals and boosting competitiveness in textiles.
