Future-Forward: Innovations for a world that does not yet exist

Planting Peace: Color-Changing Flowers Detect Land Mines

The Danish company Aresa has genetically modified the thale cress, a common weed, to turn a bright red color when it encounters unexploded land mines underground. for detection of landmines and unexploded ordnance devices on agricultural land. This biosensor is a genetically modified plant which can sense nitrogen-dioxide in soil and change colour from green to red when growing on or in near proximity of landmines. The seed has been patented to only grow with the aid of a proprietary fertilizer, but this is great innovation for peace. Buried land mines are still a significant threat for thousands of people in high conflict areas worldwide. Aresa is currently testing the seed in sites in Denmark, Croatia, and several parts of Africa.
