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.

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.

Haiti 2010 earthquake

Remote Data Team Helped Put Haiti Back on the Map

Before the Haiti earthquake, few publicly available maps of the country existed. When the earthquake hit in 2010, some of the little data that existed was destroyed. Then a team at Tufts University went into action, and from afar, helped build updated maps of roads and earthquake damage to help humanitarian organizations deal with the crisis.

Mobile Maps Help Haitians Locate Government Offices

Until last month, Haitians had no way to search online to find the location of government offices. Now, thanks to a collaboration between the Earth Institute and Haiti’s government, there’s a registry of every government office accessible online and on mobile devices.

Overcoming Challenges to Local Development in Haiti

Haiti Dialogue Series: Should funds be more effectively channeled through the Haitian government, a decentralized finance program could help streamline financing and reinforce local government planning efforts. As part of the Haiti Research and Policy Program dialogue series, Tatiana Wah was joined by Leslie Pean to discuss possible approaches to achieving the call for decentralization in Haiti that has been a part of the country’s development plans for decades, with renewed efforts after the 2010 earthquake. Most current international aid and development funding circumvents the government ministries at the national level. The lack of dedicated local budgets, as well as a weak incentive structure to attract or retain skilled professionals who are capable of complex governance, is a considerable hurdle for any decentralization proposal in Haiti.

The estimated number of people in 2010 living at different elevation levels across several Southern Asian countries.

The Intersection of Population and Elevation Examined

This map shows the estimated number of people in 2010 living at different elevation levels across several Southern Asian countries. The database it’s taken from lets users without specialized geospatial training or software compare populations in various environmental contexts in different countries.

A Sustainable Future for Haiti

The 7.0 magnitude earthquake that struck southern Haiti on January 12 caused massive destruction to human life and infrastructure—as many as 3 million people have been affected. The Earth Institute’s Haiti Policy Advisor, Tatiana Wah, who was in the country at the time of the earthquake, works with the Haitian government to develop, analyze, implement… read more
