Zambia owes its name to the Zambezi, the river that divides it from Zimbawe and which originates from Victoria Falls. Formerly known as Northern Rhodesia, it has several ecosystems due to the variety of its territory consisting mainly of the savannah and highlands that degrade along the floodplains. It is one of the most water-rich countries in Africa with 5 large lakes, 3 main rivers and 17 waterfalls. Numerous national parks protect the rich wildlife, making Zambia an ideal destination for safari and wildlife lovers. Still partially unexplored and with little-developed tourism, it keeps intact the beauty of its natural landscapes and the authenticity of its culture. Many rural areas are protected by government conservation projects, while more than 20 festivals are organized each year to preserve cultural traditions and spiritual rites of its 72 different ethnic groups.
