Miami-Dade produces just half of the food residents need

Why it matters: The U.S. depends on just over 5% of counties to produce half the crops consumers eat.

• Climate change and associated heat waves, droughts and wildfires can have an impact on food supply.

What they're saying: Miami-Dade has a particularly high "production of peppers, sweet corn and carrots when compared to other counties across the U.S.," Cameron Kruse, a scientist/storyteller who worked on the project, tells Axios.

• "However, Miami-Dade only produces about half of the calories for plant based foods demanded by its residents. In particular, people in Miami-Dade rely on grain from a number of disparate locations in the U.S.," Kruse says.

By the numbers: Miami-Dade County produces some ​​$838 million of agricultural products, according to 2017 data.

• The food that is produced in Miami-Dade — mostly grains and veggies —is primarily consumed here.

The big picture: Across the U.S., the food system is "brittle and centralized" and could be disrupted, Kruse adds.

• "The key solution is diversifying our food systems and supporting farmers using more climate-friendly agricultural practices."

Meanwhile: The team's interactive map shows the top five source counties for Miami-Dade's plant-based food are: nearby Broward, Ramsey in North Dakota, Madison in Tennessee, Lawrence in Missouri and St. Lucie near Fort Pierce.

• The research also reveals that much of our food flows through Port Everglades in Broward.
