Freshwater is valuable. Of all the water on Earth, only 2.5 per cent is
freshwater. And of all this freshwater, the total usable supply for
ecosystems and humans is less than 1 per
cent. When demand for water exceeds available supply, it results in
water scarcity. Drylands are particularly vulnerable to water scarcity.
The goal of the 2013 World Day to Combat Desertification is to create
awareness about the risks of drought and water scarcity in the drylands
and beyond, calling attention to the importance of sustaining healthy
soils as part of post Rio+20 agenda, as well as the post-2015
sustainable development agenda.
This year’s slogan, “Don’t let
our future dry up” calls for everyone to take action to promote
preparedness and resilience to water scarcity, desertification and
drought. The slogan embodies the message that we are all responsible for
water and land conservation and sustainable use, and that there are
solutions to these serious natural resource challenges. Land degradation
does not have to threaten our future.
