Stronger collaboration for an equitable and resilient recovery towards the health-related Sustainable Development Goals: 2021 Progress Report on the Global Action Plan for Healthy Lives and Well-being for All Format Executive summary Progress on the health-related SDGs was already lagging when the Global Action Plan for Healthy Lives and Well-being for All (GAP) was launched in 2019 and is now much further off track. The COVID-19 pandemic has shone a harsh light on inequities and inequality but has also underlined the centrality of health, equity and equality as preconditions for sustainable development. This second, annual GAP progress report illustrates how the GAP is providing an important, long-term improvement platform for collaboration among 13 agencies in the multilateral system as they support countries on the path towards an equitable and resilient recovery from the pandemic and further progress towards the health-related SDGs. It shows the importance of clear and shared objectives in supporting countries to achieve tangible and measurable impact through a closer collaboration of the agencies and highlights that progress has been incremental rather than transformational to date and may remain so unless Boards and donors signal to the agencies that they would like to see deeper changes to the ways the agencies work together in support of countries.
