The Bay of Plenty Regional Council is exploring ways to reduce nutrient loads to sustainable levels in Lake Rotorua.

The council has released a consultant's report on potential land management and land use changes in the Lake Rotorua catchment.

Land management group manager Warwick Murray says it analyses a suite of intervention packages aimed at reducing nutrient loads to a sustainable level.

He says although it's reported on recommended packages, these are the consultants' views only.

Warwick says the purpose of the report is to provide and analyse policy options for achieving nutrient reduction from land use.

'It looks at what the social, economic and environmental costs and benefits might be of changing land use in the catchment.

'We are using the Beca (consultant's) report as an important source of information on what can be done on land use and land management change in the Lake Rotorua catchment, and what the impacts of any potential action might be.

'It's not the only piece of information however; there is also a great deal of other supporting information that the regional council is considering.”

The council released its policy positions on land management and land use change in October, identifying the role and direction it intended to take to achieve water quality targets for Lake Rotorua.

'Changes in land use and the way activities on land are managed could decrease nitrogen inputs to improve lake health.

'The policy positions recognised that land management changes alone will not achieve water quality targets.”

Warwick says they also give priority for use of council's resources to land use change over land management changes in the catchment.

'A discussion document on land use and management change in the catchment will also be prepared for public feedback early next year.

'This will seek the community's views on outcomes they want from land use and land management change, as well as how much change they believe is appropriate.”
