Groundwater salinity is a widespread problem in our world. It causes health problems, decrease agricultural yields and profits, destroys fertile agricultural lands, jeopardizes livelihoods, increases costs of infrastructure maintenance and of industrial processes and changes or even destroys eco-systems.
To be able to manage saline groundwater, researchers, water resources specialists, policy makers and politicians need information on the scope, distribution, dynamics and severity of groundwater salinity. IGRAC contributes to provide such essential information for this broad group of people and aims to enhance their general understanding of groundwater salinity, promote early diagnosis of possible changes and widen their inspiration for selecting effective measures for interventions.
This part of the website provides information on different types of origin and occurrence of groundwater salinity on a global scale, on natural and anthropogenic drivers affecting groundwater salinity dynamics. It furthermore gives insight in how groundwater salinity may negatively (or positively) affect activities and processes. It gives a broad overview of possible measures that are undertaken worldwide to mitigate or adapt to groundwater salinity.
Comprehensive information on global groundwater salinity is available in the draft report 'Global Overview of Saline Groundwater Occurrence and Genesis'.
Recently, a paper addressing the genesis and occurrence of saline and brackish groundwater at shallow and intermediate depths was presented, during the 2012 IAH Congress in Canada.This publication, by van Weer and van der Gun, looks at the various mechanisms of saline groundwater genesis to improve understanding of salinity patterns and processes.
