Decision-making through the grapevine: Winegrowers' perceptions on climate change and the barriers to adaptation planning in New Zealand

New Zealand wine is cultivated in cool climates that produce distinctive flavours and wine-styles, which are representative of the terroir of the region. The effects of climate change can impact the quality and quantity of winegrapes, and the production of premium wine. The aim of this research was to investigate adaptation planning in the New Zealand wine industry by evaluating winegrowers’ decision-making and perceptions of climate change. Research was conducted using primary survey data from New Zealand winegrowers and semi-structured interviews with winegrowers from three case study regions of Marlborough, Central Otago, and Hawke’s Bay. The study was designed to assess how climate change is understood throughout the industry, whether adaptation plans are being developed or employed and the barriers hindering winegrowers’ implementation of adaptation strategies. The results show that winegrowers are somewhat informed about climate change with some adaptation planning occurring. However, the majority of winegrowers have no plans to adapt to climate change. The uncertainty in the climate science and the availability of information were indicated as a barrier to adaptation planning. Winegrowers convey the need for regional information with a focus on reliable forecasting and climate projections for the next few years. The New Zealand wine industry is in a positive position to undertake adaptation with the opportunity to exploit the benefits of climate change for wine production.
