How can a digital replica of Earth help us understand our planet’s past, present and future? As part of the fourth edition of Φ-week taking place this week, a group of European scientists have put forward their ideas on the practical implementation of Digital Twins and the potential application areas for a Digital Twin Earth in the real world.

In the coming decades, population growth and human activities are expected to amplify the current pressures on critical resources such as fresh water and food, intensify the stress on land and marine ecosystems, as well as increase environmental pollution and its impacts on health and biodiversity.

These threats, comprising rising sea levels, increasing ocean acidification and more intense extreme events like floods and heatwaves, will need to be closely monitored, especially for our most vulnerable populations.

Responding to these challenges, ESA came together at the 2020 edition of Φ-week to discuss how Earth observation can contribute to the creation of a digital twin of Earth – a dynamic, digital replica of our planet which accurately mimics Earth’s behaviour.

Constantly fed with Earth observation data, combined with in situ measurements and artificial intelligence, Digital Twin Earth will help visualise and forecast natural and human activity on the planet. The model will be able to monitor the health of the planet, perform simulations of Earth’s interconnected system with human behaviour, and help support European environmental policies.
