Study Shows Green Water Use Can Reduce Future Food Shortages A
study out of Stockholm, Sweden asserts that future food crises
can be avoided if water sources were revaluated and resource
management systems improved. Results of the study reveal that
integrating the use of both “blue” and “green” water can combat
food shortages resulting from future climate changes.
Researchers from the Stockholm Resilience Centre at Stockholm
University, Stockholm Environment Institute and Postdam
Institute for Climate Impact Research published their results in
the Water Resources Research journal. In the study, German
scientists found that not only “blue water,” which is river
discharge and groundwater, but also “green water,” water that is
rainwater found in soil, should be utilized in combination in
order to avoid food and water shortages. According to this
study, current water management only considers “blue water”
usable and this can lead to over three billion of the world’s
population to suffer from a lack of water as we
