Assessing design options for a Nutrient Trading System using an integrated model AgEcon
Lock, Kelly; Kerr, Suzi; Cox, Tim; Rutherford, Kit.
Water quality in many New Zealand waterways is currently declining leading to lakes and rivers being closed for contact recreation such as swimming and potentially threatening our clean, green image. Much of this decline is associated with an increase in the nutrient loss from agriculture in the surrounding catchment. Nutrient trading systems are being considered in a number of catchments across the county to restrict the nutrient loss entering the waterways and thus improve the water quality. Such a system is currently being implemented in Lake Taupo and Environment Bay of Plenty is exploring actively the use of such a system to manage nutrient loss in the Lake Rotorua catchment. Yet the design of such systems is challenging. In a collaborative effort...

Sheep and Beef Production Costs Across New Zealand: Introducing the Spatial Dimension AgEcon
Lock, Kelly; Hendy, Joanna; Kerr, Suzi.
Motu is currently developing a dataset of production costs relating to different rural land uses, which we can use to help explain historical land-use trends at a Territorial Authority level. The Meat and Wool Economic Service farm survey provides a rich database containing physical and financial data for New Zealand sheep and beef farms including detailed information on average farm expenditure, from at least 1980. But while this dataset provides extensive information for 8 farm classes and 5 regions, the actual location of the farms within each class is not known. So, we have developed an algorithm that generates a map of potential farm classes utilising supplementary information on farm location from QVNZ and a land productivity map developed by Baisden...
