The official logo for
IYDD 2006 explained:
The tree covers the logo as a protective roof, symbolizing the
combat against deforestation.
The sun, symbol life is a strong feature in deserts landscape.
The dunes are formed of several colours, the brown to
represent the intensified soil conservation, the yellow and the orange
to represent the sand dunes and all the living creatures of the desert;
and finally the green, to show vegetation and agriculture.
The "Y" opens like a hand, holding the fragile eco-system
of the desert and inviting participation in the control of desertification
and droughts.

Facts
- The 'World Day to Combat
Desertification and Drought' is 17 June.
- Nearly one-third of the earth is
classed as arid or semi-arid desert.
- An estimated six million hectares
of productive land are lost every year because of desertification,
land degradation and declining agricultural productivity.
- More than 110 countries are
affected by desertification.
- Over 250 million people are
directly affected by desertification and one billion people are at
risk. These people include many of the world's poorest, most
marginalised, and politically weak citizens.

China's land mass is desertified, with an average of 2,460 square
kilometres of land being lost to advancing deserts each year.
Nearly 400 million people live in these areas, and the economic
