A new family has now moved into Omar's old home, and he enjoys taking a look around. For him, it is a reminder of how far he has come.
"My life is easier now. When I lived in this house, I would have to wake at dawn to take my cucumbers and lettuce to the market in N'Djamena by bicycle.
"But now, I live right next to the market. I have more time to be with my family, and I can get a better price for my vegetables as well."
