Korzyści zewnętrzne prowadzenia zrównoważonych winnic w Polsce w warunkach zmian klimatu
The research aimed to determine the types of external benefits associated with running the vineyard in accordance to with the principles of sustainable production, and then, based on conclusions from the assessment of the development of vineyards growing in Poland under climate change conditions, to examine consumer opinions on their willingness to pay for wine originating from crops that generate positive externalities. It was found that the cultivation of grapes in a sustainable manner is characterized by the existence of external benefits. These benefits result from the local character of public goods, which include primarily the ecosystem described as terroir and related elements such as biodiversity and landscape. They interact in a synergistic way to other external social benefits, such as tourist attractiveness or cultural heritage. It has been shown that viticulture for wine and wine production in Poland is growing rapidly, and climate change will affect further potential development opportunities for this sector. The surveyed consumers pointed out that the wine attributes such as the organic way of production or practices responding to climate change are important for them. For the most part, they are willing to pay for it more than for features related to other external benefits, i.e. biodiversity or landscape. It is argued, that orientation of Polish vineyards to produce in a way that generates external benefits, ie. organically, will allow to take advantage of the network effect which may translate into the desire of consumers to pay a higher price for wine.
