Farming is a business. Industrial farming is a giant business. Even urban farming like this project requires inputs, labour, seeds, water and most importantly land. Food isn't free. I can't even...argh. Anyways...1. Even for-profit small farm in 3-5 acres can barely break even because farmers don't pay themselves. They usually cannot survive without a second job. Farming goals are out of the window if they want to start a family. Because babies are expensive. Secondly: when someone says a three acre farm can feed 100s if people, they probably include produce like lettuce which are not calorie or nutrient dense. You can sautéed a lb of spinach to two tbsp of cooked spinach. It's a lot of space(and $) to grow a lb of spinach! Squash and pumpkins etc are very heavy. You can grow 1000 lbs of produce from 100ft. But what does it really mean? Diverse food choices that are calorie and nutrient dense should be the key words. Having said that, this is very laudable and necessary as America has many food deserts in urban Area where people do not have access to fresh organic food. Definitely appreciate projects like this.
