Urban agriculture has been real for decades, starting with the industrialization of Western Europe in the 20th century. Urban agriculture has been also well practiced in poor economies such as Cuba, where it serves as an important way of self-reliance. Today, with conventional agriculture "Big Ag" being at a cross-road in terms of its ecological impact on the environment and the increased food demand of a population growing to 9bn people by 2050, urban agriculture may very well be one key of a solution for the 21st century. As Roman explains, urban agriculture offers the solution to grow potentially enough food in the city to feed its entire population. What's more, it also creates healthier, wealthier and happier cities, offering consumers with fresh & quality food choices and access to better quality of life. Roman Gaus, Founder of UrbanFarmers Roman Gaus (32)- from corporate career to social entrepreneur & urban farmer. Roman's story is both fascinating and inspiring. When Roman returned from the States to Switzerland, he left a short but steep career with companies such as Procter & Gamble, Novartis and Franke Group. Yet, he brought with him an emerging concept about inner-city farming, which he had seen take a grass roots approach in US cities. Back in Switzerland, Roman was surprised by the proven, Swiss-engineered technology know-how of Aquaponic; a combination of fish and vegetable farming, ideally suited to grow locally grown & organic food without soil in the city -- the idea behind UrbanFarmers was born. Determined to drive economic, social and ecological impact, Roman is now founder & CEO of UrbanFarmers AG, a pioneering Spin-off from the University of Applied Sciences (ZHAW) in Wädenswil that aims to bring sustainable urban agricultural practices into cities of the 21st century.
