We are calling for policymakers worldwide to take in the scientific knowledge synthesized in the 10 Must Knows from Biodiversity Science 2022 to inform much needed policies. At the UN Biodiversity Conference in Montreal in December 2022, your decisive action is needed to halt the man-made extinction of species and to strengthen biodiversity. The 10MustDos22 are intended to support you in taking such action by proposing solutions that can be implemented with immediate effect.

MustDo 6: Did you know that agriculture is currently subsidised to the tune of 540 billion US dollars globally [1]?

We demand that existing subsidy instruments are used specifically for the transformation of agriculture towards more biodiversity-friendly production. The nature-based use of biodiversity and the variety of ecosystem services for agricultural production reduce the use of mineral fertilisers, chemical pesticides and greenhouse gas emissions and further stabilise yields [2]. We also call for the expansion of the spectrum of cultivated species [3,4,5].
