High-resolution settlement data

CIESIN Teams with Facebook to Develop Open, Improved Settlement Data

New high-resolution population data will help us understand better how people are distributed in many countries throughout the world—as part of Facebook’s goal to connect people everywhere to the Internet.

Connecting Space to Village in West Africa

A new project, SERVIR-West Africa, will use space-based climate, weather land cover, and other NASA satellite data to address issues such as food security and the availability of fresh water in Ghana, Burkina Faso, Senegal and Niger.

Report Assesses Risks to World’s Shared River Basins

Risks for the world’s Transboundary River Basins are projected to increase in the next 15–30 years, particularly in four hotspot regions: the Middle East, Central Asia, the Ganges-Brahmaputra-Meghna basin, and the Orange and Limpopo basins in Southern Africa.

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.

Certificate Program to Focus on Environment and Security

A new professional certificate program at Columbia University will address the linkages between environment and security, aimed at practitioners with responsibility for providing assessments and warnings regarding environment-security risks or for designing programs to manage such risks.
