Its really excellent that the economist has done an in depth look at this issue and the resource challenges it has to address. Agriculture has to increase production and efficiency while using the same or less land area, using fewer inputs (fertiliser and water) all in a sustainable manner while also reducing its carbon footprint. This cannot happen via a single change, all technologies and opportunities need to be exploited. Fortunately, in some areas application of existing technology can assist, while in others "precision agriculture" and developments like genomic selection and gene editing offer potential. As a scientist my observation is that agricultural research has been "run down" worldwide for the last 30 years. Hopefully, we don't have to wait for a "panic" before it gets the attention it deserves?
