A dynamic Computable General Equilibrium analysis of increased irrigation in New Zealand.
A report to the Ministry of Agriculture and Forestry.
We used our dynamic CGE model of the New Zealand economy to estimate the economic impact of 14 proposed irrigation schemes in Canterbury and the Hawke's Bay. The results indicate that by 2035 national GDP would be 0.8% higher than baseline as a result of the irrigation schemes. This calculation takes into account the costs of repaying the debt incurred to build the schemes as well as the flow-on impacts to the rest of the New Zealand economy.
