Namibia is located in the south-western part of Africa. It borders Angola and Zambia in the north, Botswana in the east, South Africa in the south and south-east, and the Atlantic Ocean in the west. It covers about 82.4 million ha. It is one of the driest countries in the region. Rains vary from below 50 mm in the south-west to 700 mm in the north-eastern corner of the country. Namibia's forest resources constitute an important national heritage which provides both economic and environmental benefits. Due to the ecological conditions of forest growth, savannahs and dry woodlands constitute the main forest resources in Namibia.
