This interview summarizes the work of UN Global Pulse, an initiative that explores how big data and real-time analytics can help with sustainable development efforts. The director, Robert Kirkpatrick, discusses Global Pulse's mission to accelerate the use of data science to protect populations from shocks. They derive data from sources like social media, mobile phone metadata, and other digital traces to gain insights into issues like food security, public health, and economic trends. Kirkpatrick highlights challenges like building analytical capacity, maintaining responsible data partnerships, and addressing issues of data access and privacy at scale. He provides examples of projects in Indonesia that use social media to study food prices and vulnerabilities.
