Since AR5, the value of cross-sectoral collaboration to advance sustainable development has been more widely recognised, but despite acknowledgement of the importance of health adaptation as a key component, action has been slow . Building climate-resilient health systems will require multi-sectoral, multi-system and collaborative efforts at all governance scales  . Globally, health systems are poorly resourced in general, and their capacity to respond to climate change is weak, with mental health support being particularly inadequate . The health sectors of some countries have focused on implementing incremental changes to policies and measures to fill the adaptation gap .
