Old people in Widou Thiengoly say they can remember when there were
so many trees that you couldn鈥檛 see the sky. Now, miles of reddish
-brown
sand
surround
this
village
in
northwestern
Senegal,
dotted
with
occasional bushes and trees. Dried animal dung is scattered everywhere,
but hardly any dried grass is.

Overgrazing
and
climate
change
are
the
major
causes
of
the
Sahara鈥檚
advance,
said
Gilles
Boetsch,
an
anthropologist
who
directs
a
team
of
French scientists working with Senegalese researchers in the region.鈥淭he
local
Peul
people
are
herders,
often
nomadic.
But
the
pressure
of
the
herds on the land has become too great,鈥?nbsp;Mr. Boetsch said in an interview.
鈥淭he vegetation can鈥檛 regenerate itself.鈥?/p>

Since
2008,
however,
Senegal
has
been
fighting
back
against
the
encroaching
desert.
Each
year
it
has
planted
some
two
million
seedling
trees
along
a
545-kilometer,
or
340-mile,
ribbon
of
land
that
is
the
country鈥檚
segment of a major pan-African regeneration project, the Great
Green
Wall.
First
proposed
in
2005,
the
program
links
Senegal
and
10
other
Saharan
states
in
an
alliance
to
plant
a
15
kilometer-wide,
7,100-
kilometer-long
green
belt
to
fend
off
the
desert.
While
many
countries
have still to start on their sections of the barrier, Senegal has taken the lead,
