The world is faced with a growing number of complex and
interconnected challenges. Water is among the top 5 global risks in
terms of impacts, which would be far reaching beyond socio-economic
challenges, impacting livelihoods and wellbeing of the people. As
freshwater resources and population densities are unevenly
distributed across the world, some regions and countries are
already water scarce. Water scarcity is expected to intensify in
regions like the Middle East and North Africa (MENA), which has 6%
of the global population, but only 1% of the world's freshwater
resources. Climate change adds to this complexity as it is leading
to rainfall uncertainty and extended droughts periods, mostly in
arid areas. Increasing water scarcity is now recognized as a major
cause of conflict, social unrest and migration and at the same time
water is increasingly considered as an instrument for international
cooperation to achieve sustainable development. Tapping and
assessing sustainably every available option in water-scarce areas
is needed as pressure continues to build on limited water
resources. The stark fact is that conventional water provisioning
approaches relying on snowfall, rainfall and river runoff are not
enough to meet growing freshwater demand in water-scarce areas.
Water-scarce countries need a radical re-think of water resource
planning and management that includes the creative exploitation of
a growing set of viable but unconventional water resources for food
production, livelihoods, ecosystems, climate change adaption, and
sustainable development. Unconventional water resources are
generated as a by-product of specialized processes; need suitable
pre-use treatment; require pertinent on-farm management when used
for irrigation; or result from a special technology to
collect/access water.
