Spatial determination of areas in the Western Balkans region favorable for organic production

In problematic conditions for production of grapes and wine caused by the COVID-19 pandemic and the resulting occurrence of wine surpluses, producers are increasingly turning to the innovative viticulture and winemaking of products that are more appealing to the market and the consumers. On the other hand, consumption of the food safety or organic products, and therefore of organic grapes and wine, is increasingly common in the world, in particular in Europe. The Regional Rural Development Standing Working Group (SWG RRD), as a regional intergovernmental organization gathers actors in the viticulture and winemaking sector from states and territories of the Western Balkans (South-East Europe) in the Expert Working Group for Wine, with the aim of improving viticulture and winemaking in this region through joint activities. In accordance with the aforementioned, the SWG RRD is working on advancing organic production of grapes and wine, and on recognition of specificities of the terroir of wine-growing areas in Western Balkans. In addition, as part of the project “Facilitation of Exchange and Advice on Wine Regulations in Western Balkan Countries” helmed by the German Federal Ministry of Food and Agriculture, in addition to harmonization of relevant legislation with EU regulations, efforts are being invested towards recognition of organic wines. Within activities and project implemented by this organization, expert analyses and scientific research of the terroir of Western Balkans were carried out, and some of the results are presented in this paper.

The basis for production of organic grapes and wine is the achieved ideal balance between all abiotic and anthropogenic terroir factors, and one of the concepts for creating such a complex system is the selection of areas and locations with optimal conditions for (in this case organic) production of grapes and wine. This paper presents spatial determination of areas and localities that could potentially satisfy conditions for organic production of grapes and wine. Research included the territory of Western Balkans, that is, territories of members of the SWG RRD. Being the key topographic terroir factor for spatial determination of areas with favorable conditions for organic production of grapes and wine, exposure of terrains up to 600 m elevation was examined. Application of the digital elevation model (DEM) in the ArcGIS software selected areas with south, southeast and southwest terrain exposure as the most favorable exposure with respect to Western Balkans. The analyzed climate terroir factor that is significant for spatial selection of areas with high potential for organic production of grapes and wine was wind speed. GIS technology, with use of raster data from the Global Wind Atlas application, was used to select areas with favorable winds. Spatial and attribute data on median annual wind speeds in the interval between 4 and 6 m/s and in the interval between 6 and 8 m/s was analyzed.

The biggest wine producer that currently also has the most surfaces under organic vineyards in the Western Balkans region is North Macedonia. However, after the research and spatial analysis was carried out it was determined that most of the selected surfaces with favorable exposure and wind speeds can be found in Serbia and Bosnia and Herzegovina, and the highest share of determined favorable surfaces in comparison with total surfaces of relevant countries/territories can be found in Serbia and Albania.

With respect to the share of surfaces of selected areas with favorable exposure for potential organic production of grapes in comparison with the surfaces of zoned wine-growing areas, Montenegro has the highest potential with almost 6% of such favorable surfaces. Considering that the Western Balkans region has the spatially determined potential for organic production on surfaces totaling 173,252.52 ha according to the terroir factors examined in this paper, the possibility for increasing organic production of grapes and wine in specific spatially determined locations in members of SWG RRD is significant. All of this indicates the necessity for more active use of such positive terroir potentials of wine-growing areas in this part of Europe.
