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.

You can't survive long on lettuce or grapes. You need calories that means calorie dense food. Corn is the most efficient light->carbohydrate calorie converter.You need to be able to grow corn, everything else is fluff. There's ~100kcal in a head of lettuce. You'd need to eat 20 large 750g heads a day, or if you wanted tomatoes, 11kg of tomatoes. Or 15kg of lettuce...about 33lbs.

Most people don't need 2000 calories a day. Sedentary lifestyles are very common these days.

Who the heck talks about survival on urban farming?
Are you saying that if a solution is not perfect. it's a bad one?
