Ras Al Khaimah (RAK), historically known as Julfar, is one of the seven emirates that make up the United Arab Emirates (UAE). The capital city and home of most residents is also called Ras Al Khaimah, sometimes abbreviated to RAK city. Ras Al Khaimah has the most fertile soil in the country, due to a larger share of rainfall and underground water streams from the Hajar mountains. As one of the non-oil producing emirates, Ras Al Khaimah has focused on developing its industrial sector. As a result, it has one of the most diverse economies in the Gulf Cooperation Council region, with no one area exceeding more than 20% of total GDP.
