Planetary Health

Research theme

This research theme focuses on the psychological and behavioural underpinnings of planetary and environmental health. Our research aims to develop theoretical and practical solutions to implement and promote more sustainable practices for us to live within planetary boundaries.

Planetary health requires us to interrogate our current way of living and being, at economic, social and political levels, for humanity to flourish within planetary boundaries and for us to effectively assess the social impact of climate change.

This perspective has various implications in terms of behavioural and societal change. For instance, researchers are studying topics ranging from how to change the way we eat, consume, and relate to animals (including plant-based food choices, food production and consumption), to the way we consider growth in contemporary societies through activism and utopianism.

LSEiQ podcast

Ganga Shreedhar for LSE iQ October 2022_747x420

How can we survive the next mass extinction? Sea levels are rising, carbon emissions are increasing and deforestation is continuing at an alarming rate. Human created climate change is drastically reshaping life on earth, with up to 75% of the diversity of the species on our planet on their way to becoming extinct. Dr Ganga Shreedhar speaks to Anna Bevan on the LSEiQ podcast. Listen here.
