Alejandro Chaskielberg's pictures by moonlight

Drought continues to threaten the lives of as many as 13 million people living in the Horn of Africa and many are struggling to continue their pastoral lifestyle.

Photographer Alejandro Chaskielberg has been working with the aid agency Oxfam in Kenya to document those who are being offered assistance to find a new sustainable lifestyle.

Here he talks about his work and how he shoots his pictures which are lit by moonlight.
