Which principle of smart-growth encourages an increase in the use of locally grown foods?

The principle of smart growth that encourages an increase in the use of locally grown foods focuses on setting physical boundaries on urban sprawl and preserving open spaces. By establishing these boundaries, communities can limit the expansion of urban areas into agricultural land and natural habitats, safeguarding farmland that is vital for local food production.

Preserving open spaces also promotes local farming initiatives by ensuring that areas remain available for agriculture, which can contribute to more sustainable food systems. When local farms thrive due to the protection of their land, it directly supports the availability of fresh, locally grown produce for surrounding communities, thus reducing reliance on imported foods and fostering a stronger local economy.

The other principles, while beneficial for various aspects of urban planning, do not directly encourage the consumption of locally grown foods in the same way as preserving open spaces. Providing multiple transportation choices, building on abandoned properties, and integrating different types of developments focus more on enhancing accessibility, efficient land use, and mixed-use developments rather than directly supporting local agricultural systems.
