More than Half of World Population
Experiences Water Scarcity
Researchers at the University of Twente (reported in the Washington
Post) have published a study indication that 4
billion people, more than half of the world population, experiences severe water
shortages at least one month out of the year. Half a billion people experience
year-round severe water shortages. Agriculture
is the primary use of water. You can find a copy of the study here.
Water-Food Nexus: Better Water Management
Could Lead to More Food Production
There is potential for existing agricultural
lands, along with current rainwater and irrigation resources, to produce more
food, potentially halving the food gap by 2050. The greatest potential is in
dry areas such as the western U.S., Mexico, Australia,
South
Africa and China.
Developing the potential of these areas depends on careful cropland water
management. You can find more here.
