The desolate, dusty town of Pibor on South Sudan's border with Ethiopia has no running water, no electricity and little but mud huts for the population to live in.
You would be hard put to find a poorer place anywhere on earth.
I went there as part of a journey across Africa to ask the question "Why is Africa poor?" for a BBC radio documentary series.
I was asked to investigate why it is that the vast majority of African countries are clustered at or near the bottom of the United Nations Human Development Index - in other words they have a pretty appalling standard of living.
In Pibor, the answer to why the place is poor seems fairly obvious.
The people - most of whom are from the Murle ethnic group - are crippled by tribal conflicts related to disputes over cattle, the traditional store of wealth in South Sudan.
The Murle have recently had fights with the Lol Nuer group to the north of Pibor and with ethnic Bor Dinkas to the west.
In a spate of fighting with the Lol Nuer earlier this year several hundred people, many of them women and children, were killed in deliberate attacks on villages.
There has been a rash of similar clashes across South Sudan in the past year (although most were on a smaller scale than the fights between the Lol Nuer and the Murle).
And so the answer to why South Sudan is poor is surely a no-brainer: War makes you destitute.
