Piracicaba/SP - Brazil

The Brazilian Critical Zone Symposium (BCZS) is an interdisciplinary event promoted by the Soil and Plant Nutrition Graduate Program of the Luiz de Queiroz College of Agriculture/ University of São Paulo (ESALQ/USP). The BCZS aims to discuss the great challenges on environmental research in Brazil through the optics of the Critical Zone science. The main goals of the event are to propose a Brazilian network of environmental laboratories focused on long-term observation of Earth's physical, chemical and biological processes and to draw the guidelines to integrate the Brazilian Critical Zone network globally.

What is the Earth's Critical Zone? 

The Critical Zone is the portion of the Earth’s surface that includes the atmosphere, biosphere, pedosphere, and lithosphere interfaces (NRC, 2001). The Critical Zone is the thin, fragile envelope of soil, rock, air, and water that includes the land surface, and its canopy of vegetation, rivers, lakes, and shallow seas. It extends through the pedosphere, unsaturated vadose zone, and saturated ground water zone (Wilding and Lin, 2006).
