The Agriculture Research Group on Sustainability (ARGOS) monitors a wide ange of environmental, social, economic and management parameters on matched cohorts of organic, conventional and integrated farms in the sheep/beef and kiwifruit sectors. Over six years significant differences have been...

In New Zealand, regional councils have the task of sustainably managing rivers and their flows. In trying to achieve this task they face enormous challenges including the need to allocate flows amongst often highly disparate in- (e.g., angling, kayaking, native fish and birds) and out-of-river...

In an attempt to value soil natural capital, we use the inherent characteristics of soil and land valuation data to examine the relationship between soil characteristics and rural farmland values in the 6000ks2 Manawatu catchment in New Zealand. The study applies a hedonic pricing method to...

Data from a choice experiment on the community’s preferences for water quality improvements in streams was used to assess the effect of using a fixed status quo versus people’s perceived status quo on willingness to pay values. More than 50% of respondents perceived the quality of water in...
