The ongoing compound and acute crises of Covid-19 and the war in Ukraine meet longer-term but no-less pressing crises of social and environmental sustainability in and around agriculture, food and nutrition security. Many international mechanisms are already in place on agriculture and food systems which are almost unavoidably not (yet) sufficiently coordinated. A new generation of due diligence laws recently is added mostly by industrialised countries to that existing mix of policies in place addressing serious sustainability gaps of supply chains into these countries. However, these regulations also bear the risk of generating unintended negative consequences, particularly for smallholder farmers in poor countries.
