Importance

Today’s consumers increasingly demand a diet that includes fresh, high-quality vegetables free of pesticides and other agricultural chemicals. Local production is also a major factor when fresh vegetables are purchased.

Benefits to Consumers

Well-managed, local CEA operations can provide fresh produce (as well as flowers or pharmaceutical plants) of high quality and free of agriculture chemicals. Furthermore, CEA facilities can be closed in terms of discharging liquids either to surface or ground waters.

Benefits to Agriculture

Certain sectors of the agricultural industry face increasingly difficult economic outlooks. This is especially true of the dairy industry. Diversification is one means to improve the economic stability of small farmers and CEA is an option to diversify.

Benefits to Utilities
