Monitoring policy coherence for sustainable development (PCSD) will require consideration of three key elements: i) institutional mechanisms; ii) policy interactions, including contextual factors; and iii) policy effects. This broader approach can be used to assess the extent to which domestic policies are aligned with international sustainable development objectives and contribute to the achievement of the Sustainable Development Goals (SDGs). The purpose of this chapter is to explore a selection of policy interactions related to food security, illicit financial flows, and green growth – the three priority areas for policy coherence identified in the 2012 OECD Strategy on Development. Identifying and understanding the different types of interactions between the SDGs and their respective targets can help policy makers to maximise synergies and exploit win-wins; avoid potential policy conflicts; manage trade-offs; and ultimately design coherent policies for sustainable development.
