The genetic diversity contained in crops and their wild relatives is the foundation of tomorrow's agriculture, allowing farmers and professional breeders to develop the new crop varieties that agriculture needs to adapt to changing conditions. The loss of this diversity poses a considerable risk to global food security. The conservation of agrobiodiversity in situ (in nature and in agricultural practice) as well as ex situ (in genebanks) is indispensable. However, many genebanks are unable to guarantee the safe conservation of the material in their care, let alone to create opportunities for its use in plant breeding and for more sustainable agriculture. This publication gives a status update on ex situ conservation and what remains to be done.
