Three years since the adoption of the 2030 Agenda, most countries of the developing South are already in the process of translating the agenda into plans, methods and actions. In fact, while many have taken specific measures to align their national plans, policies and programmes with the agenda, others have conducted data assessment, or put in place institutional structures to provide inter-ministerial guidance to the SDG delivery process. Indeed, certain countries are trying to link the performance of the relevant ministries and officials to their contribution towards SDG implementation. This paper looks at the current state of global financial flows and their implications for the developing South; and in the light of voluntary national reviews (VNRs) presented at the High-Level Political Forums (HLPFs) of 2016 and 2017, assesses progress towards SDG implementation made by Southern countries, reviews and analyses cost estimates for implementing SDGs prepared by various developing countries, and provides other insights from the VNRS. Through the paper, the author sheds light on the disconnect between the global dialogue on SDG financing and the realities on the ground. The paper concludes by highlighting the importance of political will to take the necessary measures for implementing the 2030 Agenda.
