Contract report by EcoClimate Consortium: Integrated Research on the Economics of Climate Change Impacts Adaptation and Mitigation, commissioned by the Ministry of Agriculture and Forestry.

The report outlines climate change scenarios projected for the periods 2020-2049 (the 2030s), and 2070-2099 (the 2080s), discusses possible changes in water demand and supply for irrigation, and documents present spatial land-use patterns and productivity. Previous research on potential impacts of climate changes on New Zealand agricultural productivity is reviewed. New estimates for changes in pastoral productivity are provided, under selected climate scenarios for the 2030s and 2080s.
