The consumption and production of marketed food are spatially separated. Production is primarily in rural areas while consumption is mainly in urban areas. Agricultural marketing is the process that overcomes this separation, allowing produce to be moved from an area of surplus to one of need. Food reaches the consumer by a complex network, involving production, assembly, sorting, packing, reassembly, distribution and retail stages. In developing countries the linkage between the producer and the retailer is still usually provided by assembly and wholesale markets, where wholesale marketing takes place using a variety of transaction methods. Recent years have seen an expansion of wholesale marketing in European and former CIS countries. On the other hand, the growth of supermarkets in many regions has seen the development of direct marketing and a reduced role for wholesale systems.

Agricultural marketing covers the services involved in moving an agricultural product from the farm to the consumer. These services involve the planning, organizing, directing and handling of agricultural produce in such a way as to satisfy farmers, intermediaries and consumers. Numerous interconnected activities are involved in doing this, such as planning production, growing and harvesting, grading, packing and packaging, transport, storage, agro- and food processing, provision of market information, distribution, advertising and sale. Effectively, the term encompasses the entire range of supply chain operations for agricultural products, whether conducted through ad hoc sales or through a more integrated chain, such as one involving contract farming.
