From Reliable Prosperity:
Lacking stable market links with nearby towns and cities, rural areas are often forced to sell their products at poor prices to far-flung markets.
Productive rural areas need to establish long-term, stable market links with nearby towns and cities. This enables them to get improved prices and long-term contracts for produce, timber, fish, and other products. When producers are well known, and their products known to be of superior quality, they can differentiate themselves in the marketplace.
Community supported agriculture (CSA) is a simple example.
Rural-urban linkages help rural producers get better prices for their goods and improve their financial stability. They also connect urban consumers with pressing issues and concerns for nearby rural areas.
