Scope of theme:
By 2030 Earth’s human population will be greater than 8.3 billion with a 50% increase in demand for food and fuel and a 30% increase in demand for clean water, while mitigating and adapting to global warming . The challenge facing humanity is the increasingly intensive use of the ecosystem services provided by Earth’s Critical Zone, the near-surface environment extending from the atmospheric boundary layer to the depths of drinking water aquifers and the marine environment of the surrounding continental shelf. These ecosystem services include food production, purifying water, transforming nutrients, storing carbon, disposing of hazardous waste, providing habitat, and maintaining genetic diversity. The science challenge is the immense range in scale from that of Earth’s weathering engine, where rocks are uplifted, transformed, and transported at planetary scale to shape the Critical Zone, to rates and mechanisms of biogeochemical reactions that occur at mineral-water and organism-water interfaces . This theme addresses the current state of knowledge on how the geochemistry of Earth’s Critical Zone helps maintain these vital ecosystem services, how these have changed during the anthropocene, their tolerance to human activity and their relevance to the near-temrm habitability of our planet.
