City-grown fruits and vegetables are more carbon-intensive thanconventionally grown crops, but there are ways to address their emissions.
Fruits and vegetables grown in urban gardens in Europe and the US have a carbon footprint six times larger on average than the same produce grown on conventional farms, according to researchers.
Farmers and gardeners at 73 urban agriculture sites in France, Germany, Poland, the UK and the US participated as citizen scientists in the research led by scientists at the University of Michigan and published on Monday in Nature Cities. The study is the largest ever conducted comparing the emissions of urban and conventional agriculture.
