Human activities over a period have profoundly altered the balance of planetary health which in turn is directly linked to human health. In recent times there is a global recognition that a balance is needed among global systems of land, air, water and biodiversity to sustain and preserve life. This has been the genesis of studying the interdependencies of human and planetary health. This course will introduce the concept of planetary health, what are the current impacts due to human activities and the solutions to mitigate the risks at local and global levels. The solutions that will help populations with sustainable ways of living will be discussed and exemplified.
