Can housing trusts and co-operatives help solve the affordability crisis?
Leila Farha has an ambitious goal - to change the nature of housing markets across the world.
What she's wanting to happen is to move away from the financialisation of the housing market, which appears to be increasing inequality, and benefitting the most affluent at the expense of everyone else.
Her ideas revolve around the use of land trusts and housing co-operatives to offer an alternative model of housing provision, not least for those people on low incomes and to move away from a rentier-led model of private sector renting.
It's certainly got lots of work to do.
