Agricultural Technology - Feeding 9 Billion People by 2050

Agricultural Technology -  STEM Projects

How will we feed the world population by the year 2050? The United Nations projects that by 2050 the world population will have risen to 9.7 billion people—more than 2 billion more people than today! To feed everyone, we will need a lot more food, which makes agricultural technology incredibly important. Agricultural technology is the use of science, engineering, and technology to make agriculture (farming) better. This can mean a wide range of things, including preventing plant diseases, gathering data to optimize crop yield (the amount of food you can grow on a piece of land), using resources like water more effectively, or even creating more nutritious versions of a vegetable!

Try one of the projects below to explore some of the solutions farmers, researchers, and engineers are trying around the world. Maybe you'll be working alongside them one day making sure we can feed everyone.
