The population will continue to grow at high speed well into the future. Today, there are more than 7 billion people in the world, and by 2050 the number will increase to 9 billion. This means we will need significantly more food in the future, but the Earth’s resources are limited… We need to feed more people from the same amount of arable land. Which technologies can help us improve yields in a sustainable way? Professor Louise O. Fresco, President of Wageningen University & Research in the Netherlands, shares her vision. We asked experts in different fields about what is causing these declines – and what we can do to reverse the trend. Crop protection plays a key role in improving yields. How does BASF develop products that are safe for people and the environment? How do digital technologies help farmers around the world to increase yields and improve sustainability? A BASF project in Chile offers new perspectives to young people. Scents rule our emotions. We explore how they do it and how they can be produced synthetically. Waste mountains are growing rapidly. There is still a lot of potential for the intelligent reuse of plastic, electronic scrap and the like as raw materials.
