Planetary Health is a concept that advocates the care of the planet for human own survivability. It underscores the health implications of environmental degradation brought about by human activities and development progress, and calls for a systemic approach that considers and addresses socio-environmental trade-offs of certain policy and/or economic objectives. In view of multiple crises that have been happening in recent years – from the COVID-19 pandemic to the war in Ukraine – which have further negatively affected the environment, understanding how Planetary Health can be applied to address continuing environmental decline is critical. Planetary Health is a relatively new term in Asia. Drawing from the discussions in the 6th NTS-Asia Consortium Annual Conference in April 2022, this NTS Insight maps the different ways Indonesia, India, Bangladesh, Japan, and China engage Planetary Health in their specific contexts. The interpretations of the concept are likely to influence the trajectory of its implementation.
