The food price crises 2007-8 stimulated international policy reaction and a renewal of the policy agenda at the global level of food security governance. Reviewing the policy agendas resulting from these international meetings reveals that policies to directly address the environmental challenges facing the world’s food supply remain marginalised. The focus is on improved technological applications to food production and supply management efficiencies, alongside land use and ownership. Equally, the global climate change regime’s agenda failed to prioritise agriculture and its ecosystem vulnerabilities. Yet, there is strong scientific evidence and advocacy for addressing food’s environmental and ecosystem challenges. The paper draws on theories of the governance of socio-technical transition and policy agenda formation, to investigate the key shaping factors upon the contemporary food security agenda and to identify the advocacy voices and policy nodal points that are seeking ways to link up these currently separated global policy regimes.
