The food and agriculture sector is both a major contributor to climate change and especially vulnerable to its worst impacts. This means that much is at stake in what is a complex set of contested political dynamics as new governance agendas are rolled out. On one hand, there is a strong push for ‘climate-smart agriculture’ (CSA) and related initiatives in the area of marine resources such as the idea of the blue economy, as an attempt to bring a range of viewpoints together to address the interrelationship between these ecological and economic systems. On the other hand, critics see these strategies as promotion of more of the same kinds of policies that created stress in the climate–food system in the first place. To unpack these issues, this special forum brings together a collection of papers that highlight three overlapping themes that lie at the centre of these debates, yet which have not been fully acknowledged by those implementing CSA initiatives: the role of power and interests in shaping governance approaches to climate and food systems; the ways in which existing approaches, primarily those promoting open markets and technology, are reinforced in governance initiatives; and the sidelining of questions of inequality.
