With the help of satellite data, yields can be estimated both over a wide area and at individual field level. This is also possible in small-scale Swiss agriculture, as shown by a team consisting of ETH Zürich, the University of Zurich and Agroscope.
Suitable both as food for humans and as livestock feed, sorghum thrives even in an increasingly dry climate. Agroscope has developed maps showing the potential growing areas for silage- and grain sorghum.
The energy expenditure for staggered greenhouse tomato production would be twice as high as that of the current means of production with no appreciable increase in yield. Even so, the current means of production might benefit from LED lighting.
