Ecologist Lian Pin Koh makes a persuasive case for using drones to protect the world's forests and wildlife. These lightweight autonomous flying vehicles can track animals in their natural habitat, monitor the health of rainforests, even combat crime by detecting poachers via thermal imaging. Added bonus? They're also entirely affordable.
 
Meet Lian Pin Koh, a relentless tinkerer and science fiction movie geek, though most know him as an environmental scientist. His dreams of combining these interests led him to co-found, with colleague Serge Wich, the site ConservationDrones.org, a project dedicated to gathering intelligence on forests and wildlife through the use of low-cost unmanned flying machines.
Ground surveys are expensive, and are not conducted at a sufficient frequency. Furthermore, some remote tropical forests have never been really surveyed for biodiversity. Koh's machines have already collected valuable information in Sumatra, Congo, Gabon, and Madagascar.
He is an assistant professor of applied ecology and conservation at the ETH Zurich.
What others say:  “Although it's still the "dawn of drone ecology," as one innovator calls it, these unmanned aerial vehicles are already skimming over Indonesia's jungle canopy to photograph orangutans, protecting rhinos in Nepal and studying invasive aquatic plants in Florida... A conservation drone pioneer, Lian Pin Koh of the Swiss Federal Institute of Technology, says the idea came to him after another sweaty, jungle slog in Sabah, Malaysia, hauling heavy equipment for his field work.” — Denis D.

This Ted Talk was filmed in June, 2013:  A Drone's -Eye View of Conservation.
 
 
A billion people in the world lack access to all-season roads. Could the structure of the internet provide a model for how to reach them? Andreas Raptopoulos of Matternet thinks so. He introduces a new type of transportation system that uses electric autonomous flying machines to deliver medicine, food, goods and supplies wherever they are needed.  Another positive creative use of drones shared by Ted Talks in June, 2013.
