Imagine a farming future that is 100 times more productive on the same amount of land. Few or no pesticides are required. As much as 95% less water is required. No soil is needed. Crops can be grown year-round, with less labour and where the labour requirements are consistent and sustained across the year. In this future, crops…

How safe is our food? We probably don’t consider food safety all that often. As with so many things, however, COVID-19 made us think about issues that often go unnoticed. Could the virus be transmitted on food or food packaging? So far there is no evidence that COVID-19 is associated with handling or eating food. But…

Clarity on the…
