Revitalizing Africa’s Soils
To feed our burgeoning global population, the world has to at least double crop yields by 2050, by improving seeds of high yielding crops and cultivating healthy fertile soils. A new on-the-spot soil testing kit will help meet this challenge.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
