Commercial urban agriculture is on the rise, with small-scale farms in New York City like Gotham Greens, which reduces the amount of energy, land use and food waste in tight, underutilized spaces to produce herbs and roughage for the masses. In Austin, Texas, backyard farms and urban gardens sell ingredients to restaurants and markets throughout the region, as do similar projects in Los Angeles. In fact, innovations allowing farmers to grow without soil or natural light expand the potential for food sourcing in urban areas. Urban farming has increased by over 30 percent in the past 30 years, with no indication of slowing down. Urban land could grow fruit and vegetables for 15 percent of the population, research shows.
