Over the next decades, agriculture will undergo a transformation as farmers learn to produce more food while decreasing the environmental impact of their practices. Between feeding another two billion people and adapting to climate change, we face unprecedented challenges. However, at the same time, there has never been as much interest in agriculture as more and more consumers want to know the origins of their food and new farmers are increasingly from non-farm backgrounds.
