The John Wesley Powell Center for Earth System Analysis and Synthesis supports proposal driven working groups to examine some of the most pressing questions and needs for scientific synthesis across the USGS Mission Areas. Working groups are funded to work with existing data as opposed to collecting new data, and the data synthesis results of all projects are published along with journal articles and other products. ScienceBase provides the data backbone for Powell Center working groups. It is used to catalog data and information resources used by the working groups and is the repository for products coming out of the working groups. Wherever possible, new data from working groups are made part of some larger data...

Global climate change is putting unprecedented pressure on global croplands and their water use, vital for ensuring future food security for the world's rapidly expanding human population. The end of the green green revolution (productivity per unit of land) era has meant declining global per capita agricultural production requiring immediate policy responses to safeguard food security amidst global climate change and economic turbulence. Above all, global croplands are water guzzlers, consuming between 60-90% of all human water use. With increasing urbanization, industrialization, and other demands (e.g., bio-fuels) on water there is increasing pressure to reduce agricultural water use by producing more food from...
