Since fighting broke out in Sudan on April 15th this year, more than million people have been displaced internally and internationally. Many of the borders across which Sudanese have fled are not functional borders -- that is, there is no process to register or screen people who are entering a country. According to my guest today, non-functional porous borders are exacerbating an aleady dire humanitarian crisis. 

Margaret Monyani is a senior migration researcher at Institute for Security Studies in South Africa. We kick off discussing why the African Union is focusing more heavily on border control and administration before having a longer conversation about what Sudan's refugee crisis tells us about African borders today.
