Abstract
The German grain legume market is characterized by fragmentation and limited competition, restricting farmers’ market access and legume cultivation. The aim of this study is to analyze the current trader structure and optimize its configurations using k-means clustering. Results reveal a concentration of traders in southern and western Germany, while many farmers lack access to traders, even within a 100 km radius. A more competitive market can be achieved without increasing the number of traders, but by expanding their trading distance between farmers and dealers. Optimized site selection is of central importance in this context. Policy should create incentives – for example, by supporting digital platforms – that encourage farmers to engage with more traders through improved information and transparency, and conversely, motivate traders to expand their service radius via drop shipping.
