Many countries are making progress on improving water sanitation and protecting marine ecosystems. But air pollution continues as a leading health problem in many nations, and fisheries are deteriorating almost everywhere.
When it comes to learning about data collection techniques, there is no substitute for field work. In October, three Columbia classes embarked on a field trip to the Black Rock Forest in Cornwall, New York, to get some hands-on experience.
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.
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.
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.
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.
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.
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.
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.
