Singapore Works: Caring for 2 million trees no easy feat

Singapore is one of the world's top cities for its urban greenery.

When it comes to urban tree density, Singapore stands tall - it outshone 16 cities around the world in a study by researchers from the Massachusetts Institute of Technology and the World Economic Forum.

Taking care of these trees is no easy feat. NParks is currently testing new technologies to make the process more efficient.

For instance, it is testing a microdrone to help with the aerial inspection of the crowns of trees.

The lightweight mini quadcopter cuts the time required for inspection from a full day to just 30 minutes.

Go behind the scenes to witness the hard work involved in managing the garden city, in the latest episode of Singapore Works.

• Singapore Works is a video series about the people and processes behind the scenes that enable Singapore to function seamlessly.
