Climate change and human activities impact soil and water resources stressing communities worldwide. Extreme weather events are causing floods and droughts, leading to problems with soil and groundwater salinization. Many historically densely populated and agricultural areas are particularly vulnerable toclimate change and subjected to saltwater inundation and secondary salinization. Detailed maps of the subsurface are necessary to manage and ameliorate saliny but difficult to obtain, as salinity is dynamic and highly spatially variable. Our group has been developing several on-ground geophysical instruments and geostatistical approaches (Pozdnyakova and Zhang, 1999) for studying soil and groundwater salinity around the world for the last 20 years.
