A Lost Haven for Early Modern Humans
Sea level changes have repeatedly reshaped the Paleo-Agulhas Plain, a now submerged region off the coast of South Africa that once teemed with plants, animals, and human hunter–gatherers.
Hydrology Helps Identify Future Malaria Hot Spots
Complex hydrological processes—not just the amount of rainfall—help determine where malaria-transmitting mosquitoes can thrive.
Minireservorios Podrían Salvar a Agricultores con Suelos Arenosos
Una tecnología de retención de agua subterránea recientemente reactivada podría conservar el agua y aumentar drásticamente el rendimiento de los cultivos en paisajes áridos con suelos arenosos como el África Subsahariana.
Trans-Atlantic Dusts May Not Enrich Amazon as Much as Thought
New research indicates that nutrient loads delivered to South American ecosystems by dust originating in Africa are far lower than suggested in previous studies.
Ethiopia’s Coffee-Growing Areas May Be Headed for the Hills
New research suggests climate change may radically redefine the regions best suited to grow one of Ethiopia’s most valuable crops.
