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 well as food. With the new consideration of using “green water,” scientists say that a basis for a “new green revolution” can be formed. Scientists go on to say using both water types can reduce climate change caused by humans and that can decrease the amount floods and droughts worldwide.
