Let’s Go Nuts: A Suitability Analysis of Persian Walnut Cultivation on Mount Lykaion, Arkadia, Greece The villages of rural Greece are dying. In no place is this more apparent than in the heart of the Peloponnese, in which lies the Parhassian Heritage Park. In an effort to support the economic opportunities of the area, this project investigates the cultivation of Persian walnuts in the Mount Lykaion character area of the park. The Persian walnut (Juglans regia) is a traditionally cultivated crop in the area and is grown not only for the nuts, but also for traditional products, such as candies and liquor. These value-added products offer an economic opportunity to the people still living in the area that functions within their traditional way of life. But first, in order to take advantage of this local resource, walnuts must be cultivated in a more rigorous way. To achieve this, I generated a suitability surface using a combination of raster elevation data, vector stream and road data, and control data collected in the field, based on where walnuts are already growing. This suitability surface was then applied to the entire study area, thus identifying any areas where walnuts could potentially be grown. This study presents a crucial first step toward a viable value-added product by identifying areas in the Mount Lykaion character area of the Parhassian Heritage Park that are suitable to cultivating walnuts.
