As climate change and trade tensions continue to put a strain on our food systems, a University of Guelph researcher says greenhouses and other forms of controlled environment agriculture (CEA) provide a solution by growing food close to where most Canadians live.

Dr. Youbin Zheng is a professor in the School of Environmental Sciences who studies plant production in controlled environments. He says because many greenhouses and indoor food farms use soilless production systems, food can be grown even in urban areas, near the people who will consume it.
