Lankien does not exist on Google Earth. In fact, it does not exist on any digital map that I could find on the Internet. I did find a map with Lankien on it at the infamous Yaya Centre in Nairobi, so I do know where I am. However, to give a clearer picture, I added Lankien to the following map.
Sudan is the largest country in Africa . It is about a quarter of the size of Canada but has more people, 40 million compared to Canada's 33 million. It shares borders with no less than eight other African countries and the Red Sea. Lokichoggio, MSF's base of operation for southern Sudan, is tucked into the north-west corner of Kenya.
Lankien is east of the White Nile. The White Nile and the Blue Nile join each other at Khartoum, then the Nile proper flows north to Egypt and the Nile delta. Most of the water of the Nile comes from the Blue Nile and its source, Lake Tana, in the Ethiopian mountains. The water of the White Nile gets lost in southern Sudan in a huge swamp called the Sudd.
In the north, Sudan is mostly desert, but southern Sudan is a huge, clay plain. There are no major mountain ranges to break up the weather which is dominated by a dry north east wind from the Arabian Peninsula and a wet south west wind from the Congo Basin. It is this wet south west wind that is beginning to drive the weather in Lankien.
As you can see from the map, we are between 5-10 degrees north of the equator.
