During my time living in Kabul, Afghanistan, I witnessed the harsh living conditions of the people in the slums that ring the city. It was part of the reality of a country dealing with decades of conflict and insecurity. These slums, known as the Kabul Informal Settlements, are populated by Afghans who had to flee their homes. Many are Afghan refugee returnees, or others uprooted by conflict. Throughout Afghanistan, more than 600,000 men, women and children are living away from their homes, and most of them in urban areas.
