A damning report from the Urban Development Institute of Australia shows Brisbane risks falling behind other capital city areas in supplying land and housing for its growing population.

According to the State of the Land paper, Brisbane's lot production has trended downward for the last decade and now sits 45 per cent below pre-global financial crisis levels.

The paper also recorded year-on-year increases in the median price of lots over the last decade, with the median price now sitting at about $220,000.

UDIA National President Julie Katz said the report painted a concerning picture for policy makers, because the increasing under supply of land and housing put substantial pressure on housing affordability.
