Six years ago Sunday, South Sudan's flag was hoisted in Juba.

Amid an atmosphere of optimism and hope, South Sudan became the world's newest country, breaking away from its longtime rival, Sudan.

The moment marked the end of decades of fighting between rebels in the predominantly Christian south of Sudan and their northern Arab rivals in the Sudanese capital, Khartoum.

NPR's Ofeibea Quist-Arcton, who was in Juba that day, reported that with the parades and children singing, there was a mood of excitement.

The number of people forcibly displaced from their homes is the highest since World War II.

According to a new report from the United Nations Refugee Agency, UNHCR, 65.6 million people are currently living as refugees or as displaced persons inside their own countries. This includes 10.3 million people who were uprooted from their homes in 2016.

Over the last 2 years photographer Nichole Sobecki and journalist Laura Heaton have documented the devastating impact of climate change on one of the most unstable places in the world, Somalia.
