This chapter discusses the aggregate effects of international regimes on Plant Genetic Resources for Food and Agriculture (PGRFA) in the Philippines and the relevance of the findings for developing countries. The driving forces that produced this regime interaction transform and channel their interests and ideas into these developments along various patterns mechanisms of influence which can be traced across scales from the international to the national level: structural power that is the power to shape political-economic structures; learning and norm diffusion; institutional capacity. This chapter shows how the driving forces shaped the regime interaction pertaining to PGRFA management through these mechanisms of influence. It also shows how the identification of mechanisms influences and their patterns of work provide entry points for actors to shape governance in agrobiodiversity at the international as well as national levels. New options have emerged after the entry into force of the ITPGRFA in 2004.
