From robotic devices that treat urine patches to alternative crops, the judges of the Rotorua Land Innovation Challenge look set to have a tough job narrowing down the winner.
The challenge aims to generate additional land uses for the Lake Rotorua catchment as part of efforts to clean up the water quality and generate ideas for land owners required to reduce nutrient loss.
Bay of Plenty Regional Council natural resources operations manager Warwick Murray said challenge organisers were pleased to have received 12 entries to the challenge.
The top prize on offer was $20,000.
"This is an excellent number given the considerable work that was required to prepare an entry and the extensive criteria that entries had to meet, including the provision of data and information to back up the proposed land uses."
