Zusammenfassung:The "Prosecco Hills of Conegliano and Valdobbiadene" has been inscribed in the UNESCO World Heritage List since 2019 under the category “cultural landscapes”. The study analysed land use and landscape changes in the last six decades through spatial analyses and landscape metrics, identifying main changes and comparing similarities and differences between the Core and the Buffer Zone. The main aims were to identify the main drivers that contributed to the preservation of the traditional cultural landscape and to provide data and indications for landscape planning and conservation, with particular attention to the opportunities/threats due to the expected increase of tourism resulting from the recent UNESCO recognition. The study was conducted in the framework of the UNESCO site Management Plan. Results demonstrated that the Core Zone traditional landscape has a higher level of integrity compared to the Buffer Zone, due to the different terrain morphology that represents the main driver. The rough morphology of the Core Zone contributed to the preservation of traditional vineyards interspersed with small woods, linear tree formations and forest patches, as it was not possible to introduce mechanisation in viticulture due to steep slopes that oblige farmers to cultivate vines on ciglioni (earth terraces). Core Zone's main change was due to forestation (21% of the surface) on steeper slopes and higher altitudes, caused by the abandonment of pastures that occurred in the last decades. The main transformations in the Buffer Zone were agricultural intensification (29% of the surface) due to the replacement of traditional mixed crops, meadows, and arable land with modern and mechanised vineyards, and urban sprawl (average rate of 10 ha/year). The study highlighted that despite land use changes the Buffer Zone still contributes to the conservation of the overall UNESCO site landscape quality. Buffer Zone can also have a potential key-role in mitigating the increasing tourist flows, but additional urban sprawl or the spread of other modern vineyards should be avoided. The main long-term objective should be the preservation of the cultural landscape and the peaceful coexistence of farmers, local population and tourists, with mutual benefits, by applying a participatory approach. •The "Prosecco Hills of Conegliano and Valdobbiadene" is a UNESCO cultural landscape.•The Core Zone rough morphology contributed to traditional landscape preservation.•Buffer Zone faced agric
