Namibia's surface area is 824,268 km² with three major categories of land tenure: the so-called commercial farmland with freehold tenure (approximately 42% of the country situated predominantly in the south and centre of Namibia), communal areas which are situated mainly in contiguous blocks in the northern Namibia (approximately 35% of the country), and the state land including conservation areas (approximately 23% of the country).1 Namibia has common borders with Angola, Zambia, Zimbabwe, Botswana and South Africa and a coastline of 1,572 km at the Atlantic Ocean to its west. The Ocean with its cold, nutrient rich Benguela Current has a significant influence on Namibia's climate, vegetation and marine life. Main geographical areas in Namibia include two of the largest and most important great deserts, namely the Kalahari Desert in the east, which is dominated by stabilised dunes and the Namib Desert in the west, which comprises a wide range of landscape types. The Central Plateau with its Great Escarpment lying in the inland of the Namib plains and rising up above them is the third great landscape unit in Namibia.
