Helping Communities Respond to Climate Change

A new tool helps scientists communicate better with communities on global climate change issues, increasing awareness and stakeholder engagement.

Figure of two images. The one of the left shows 2015 estimates of population density of a coastal region in Kenya from CIESIN’s Gridded Population of the World, version 4 (GPWv4), which is based on census data. On the right, New Facebook estimates of population density in the same coastal region in Kenya. This allocation, which is derived from processing of third party satellite imagery and incorporates GPWv4, provides a higher resolution map of population distribution.

Working with Facebook to Create Better Population Maps

Knowing how settlements are distributed across the landscape—e.g., in clusters, along roads or waterways, or scattered widely—has important implications for designing infrastructure, improving access, and promoting sustainability.
