Analysing linkages between SDGs

The iSDG model is an integrated simulation tool that enables policy makers and planning officials at all levels of government to understand the interlinkages between policies designed to achieve the SDGs and test their likely impacts. By bringing together the social, economic and environmental dimensions of sustainable development into one framework, the model enables broad, cross-sector and long-term analyses of the impacts of alternative policies. Simulating trends until 2030 under a business-as-usual scenario, the iSDG model is especially useful both in the early stages of policy design to support scenario exploration, and in advanced stages when specific interventions can be jointly simulated to assess their combined effect and emerging synergies.

Country case


UNDP supported the Government of Nigeria to apply the iSDG model in 2019 to strengthen planning and prioritisation of interventions aimed at accelerating impact across the SDGs. The analysis showed that the national Economic Recovery and Growth Plan (2017-2020) can boost progress on many Goals but must be integrated with interventions for climate change adaptation and protection of marine resources to generate sustainable results. The analysis also showed that investments in decentralised renewable energy is a potentially strong accelerator that could improve social, economic and environmental targets.
