Aqueduct is an online database, created by the World
Resources Institute, that lets its users to combine 12 important indicators of
water risk to build global overall water risk maps. The 12 indicators are such
as baseline water stress, inter-annual variability, seasonal variability, flood
occurrence, drought severity, upstream storage, groundwater stress, return flow
ratio, upstream protected land, media coverage, access to water, and threatened
amphibians. It shows us areas that have water quality problems, gives us
predictions for floods and droughts, supply-to-demand ratios, and many other
details. Each location is given a certain risk score, and heat maps provided in
the database points out which areas have the biggest problems. This database
has been used by many companies, investors and even governments to make global
policy decisions regarding water scarcity, particularly.
The downside is that this database is based on the water
scarcity data for the last three years, causing this database to provide
results that are not fully precise or true.
The advantage of this database is that it helps many
people to predict and understand many areas with water scarcity and quality
problems.
