Lake Kariba is the biggest man-made Lake in the World. But apart from that it is situated in the Zambezi valley on the Kariba basin. The area is very hot in summers and very dry as well. The Lake provides livelihood to hundreds of animal species and birds. There are a number of national parks along the Zambezi river and the Lake Kariba owing to the availability of water and grazing on the banks and on the islands that mushroom the Lake.
