The future of farming

Show notes

Food security expert [https://sustainability.stanford.edu/people/david-lobell"]( David Lobell is immersed in the data of agriculture. He uses satellite imagery, yield data, and advanced computational modeling to analyze the roughly 500 million farms worldwide to increase productivity and ensure global food security – now and in the future. Though food is often taken for granted, feeding a hungry world is our greatest environmental challenge, he says. Lobell goes on to explain how data can do much more than increase yields – it also cuts costs, prevents conflicts, reduces emissions and deforestation, and improves nutrition. Smart farming is key to food security and avoiding the problems that stem from hunger, Lobell tells host [https://bioengineering.stanford.edu/people/russ-altman"]( Russ Altman on this episode of Stanford Engineering’s _The Future of Everything_ podcast. _Have a question for Russ?
