Whereas the number of people living in cities worldwide is continually growing, the already scarce area used for growing food and resources has been steadily shrinking.
This disparity, however, can be partly bridged by urban farming, the practice of growing food in cities and urban areas. Fraunhofer IAO has published a study investigating how cities could benefit from locally grown food and resources, looking at indoor plant and microalgae cultivation.
Safeguarding the long-term supply of food and resources to urban areas is a growing challenge – particularly in densely populated cities with limited access to surrounding agricultural land. Furthermore, intensive farming practices and heavy use of chemicals are putting increasing pressure on natural resources and land.
Algae farming is tough sledding.

> entirely an advantage for the farmer, and for the anti-pollution folks who are against trucking.
And also for people who have an interest in urban food security. I mean suppose some kind of highly disruptive event [bbc.co.uk] meant that getting food from the countryside into the city suddenly became difficult. within a few weeks you have millions of people trying to live off nothing but rats, cats and pigeons. If you have at least some production within the city limits then the problem will be at least mitigated.

Any weather disaster that shuts down a city will shut down most crops. Staple foods take 5 months to a year to grow, so its going to be a really rare disaster where nearby food production will save the day.
What IS a priority for many nations is having enough farm production in their country, just in case they can't import food for some reason.
People really do need a personal emergency food supply, just can't grow anything fast enough even if you have all the tools and space necessary.

Food security means calories, not traces of micro nutrients.
