Modelling economic impacts of water storage in North Canterbury AgEcon
Daigneault, Adam J.; Greenhalgh, Suzie; Lennox, James A..
Despite the importance of the agricultural and downstream processing sectors in the New Zealand economy, there is no tradition of using partial or general equilibrium models to evaluate policies or other measures directed at the agricultural sector. Policy-makers have instead relied on the development of ad hoc scenarios of land use change, farm budget models, and simple multiplier analysis of flow-on effects. To redress this situation, we have developed a catchment-scale partial equilibrium framework based on the US REAP model, which we have thus far calibrated for two different catchments. In this paper, we present an application of the model to the Hurunui Catchment in North Canterbury in which we assess several scenarios for the development of...

Estimating Co-benefits of Agricultural Climate Policy in New Zealand: A Catchment-Level Analysis AgEcon
Daigneault, Adam J.; Greenhalgh, Suzie; Samarasinghe, Oshadhi; Sinclair, Robyn.
This paper uses an economic catchment model to assess changes in land use, enterprise distribution, greenhouse gas emissions and nutrient loading levels from a series of policies that introduce carbon prices or nutrient reduction caps on land-based production in the Hurunui Catchment in Canterbury, New Zealand. At $20/tCO2e, net revenue for the catchment is reduced by 7% from baseline levels while GHGs are reduced by 3%. At $40/ tCO2e, net revenue is reduced by 15% while GHGs are reduced by 21%. Nitrogen and phosphorous loading levels within the catchment were also reduced when landowners face a carbon price, thus providing other benefits to the environment. Additional scenarios in this paper assess the impacts from developing a large-scale irrigation...
