The aim of this module is to understand how food security is affected by policies, environmental processes, and actions that occur at the international level. Food security is a central theme, and how it is constructed and contested at international level, involving global institutions, interest groups, and diverse policy agendas. This exploration does not confine itself exclusively to production, but also considers other areas of concern, including: global environmental change, dietary shifts, `post-production' concerns with food quality or ecosystem integrity, agribusiness, public versus private agricultural innovation, intellectual property rights, and strategies for technological development. Students will gain critical understanding of these debates and how different policy actors engage with them at both the local and the global level. These actors include firms, public R&D institutions, civil society, farmers' movements, consumers' groups, and major donors and philanthropic organizations. The module will help students develop a critical and inter-disciplinary understanding of key international policy debates that have relevance to agriculture. Additionally, students will gain a better understanding of how trends in globalised agriculture affect poor people, particularly smallholder farmers, but also consumers and those involved in value chains.
