The secret lives of IIASA scientists part 1: From Everest to systems analysis

In his early years, IIASA researcher Michael Thompson was a Himalayan mountaineer. Navigating risk in the mountains has defined his view on risk more generally, thereby influencing his research on environment and development in Nepal.

Identifying global poverty from space

Despite successes in reducing poverty globally in the last two decades, almost one billion people are still living without access to reliable and affordable electricity, which in turn negatively affects health and welfare, and impedes sustainable development. Knowing where these people are is crucial if aid and infrastructure are to reach them. A new IIASA-led study proposes a novel method to estimate global economic wellbeing using nighttime satellite images.
