New Zealand freshwater management and agricultural impacts

In New Zealand, it is increasingly recognised, including by government, that water resource allocation and water quality are issues of national importance. Agriculture is frequently portrayed by public media as a major user of water and a major contributor to worsening water quality. We outline the water management systems in New Zealand, and the use of water by agriculture. Official reports on agriculture's impact on New Zealand water availability and quality are summarised. We report how the New Zealand public perceive water, its management, and the roles of agriculture in water issues. Data from a nationwide mail survey were analysed to determine how New Zealanders assess the state of New Zealand lakes, rivers and streams, and aquifers, the performance of three agencies responsible for management of freshwater resources, and willingness to fund stream enhancement. We provide brief explanations for the failures of water resource management in New Zealand and report on options, including community-based responses that might address some of the mounting public, scientific, and government concerns about trends in water quantity and quality. A willingness to pay proposition, concerning riparian areas, included in the nationwide survey provides some evidence that the public are willing to pay for improved waterway management. Relevant non-market valuation studies also indicate that the public places considerable value on preservation values of water in New Zealand.

Prioritizing Sustainability Indicators: Using Materiality Analysis to Guide Sustainability Assessment and Strategy

Despite the growing awareness of complexity in sustainable development, the practical implementation of sustainability assessment through the use of sustainability indicators requires prioritizing the myriad indicators available. This study identifies the highest priority sustainability indicators for the New Zealand wine industry using materiality analysis. Thirteen information sources representative of different stakeholder perspectives considered to drive the need for sustainability assessment are analysed to provide a measure of sustainability issue salience and risk. Based on a meta-analysis of relevant information, it is found that environmental issues make up the highest priority issues, followed by social issues relating primarily to worker wellbeing. Significantly, economic and governance issues were not found to be high priorities. These findings are discussed in the context of the common bias in agricultural sustainability assessment towards environmental issues, and the broader business implications for sustainability assessment, strategy and policy
