The politics of plants

Food security is not a new concern, but has taken on new dimensions in recent years. Here we position food security in a broader context relating to the use and management of global biomass resources, and specifically the push to develop a 'bio-based economy'. We note a growing focus on plants as a source of innovative solutions to complex problems including food security, energy security, climate change and global environmental health. However, we also note that plants are a renewable but finite resource, and propose that renewed enthusiasm for plants is resulting in an increasingly complicated 'politics of plants,' as competition for limited land and biomass resources intensifies-the clash between food security and energy security over biofuels being an obvious example. Plants are a common thread across many policy domains including agriculture, energy, environment, health, and industry, and as such we suggest that they might provide a focal point for joined-up thinking and governance. We identify this broader picture as an important backdrop for discussions regarding food security, and from our proposed framework develop a number of recommendations for further investigation.
