Grave dilemma: S.African cities short of cemetery space

In Johannesburg, land is a hot topic, even for the dead. Population growth, migration to urban areas and an influx of foreigners has put huge pressure on land in urban areas. Adding to the problem is a cultural resistance to the practice of cremation. Between 45 and 60 graves are re-opened each week on average to allow for second burials in Johannesburg, the country's largest city and economic hub.
