Ever wondered what makes our landscapes fertile and beautiful to behold? This fascinating interview with Dr Suzanne Prober from the CSIRO's Land and Water division, chatting with TEC's Ruth Hessey, makes it sound simple.

Reckless land clearing and poor water management, says Dr Prober,  threaten our future food security. But there are lots of smart people on the land working with regenerative plants and seeds to safeguard the very fabric of our survival.
