Ghana is a global gold mining powerhouse and Africa's biggest producer.

The informal mining sector of gold – known locally as “galamsey” - is a big election issue here. There have been recent marches demanding tougher action against illegal miners in Accra. But illegal mining is also a major source of employment. More than a million Ghanaians make their living from galamsey.

We hear from local galamsey miners and look at the negative impact this industry is having on both the workers in terms of health, the environment, and the wider community.
