THE DETROIT JEWISH NEWS
Israel Intensively Using All Its Water Resources
A recent article by Peter
Gwynne and Milan J. Kubic
in Newsweek magazine de-
scribed Israel's intensive
use of water resources.
Since 1950, Israel has in-
creased its water utilization
from 17 percent to almost 95
percent. Experts attribute
such success largely to
shrewd planning. When Is-
rael became a state in 1948,
the founding fathers im-
mediately proclaimed all
water a national property
and entrusted it to an inde-
pendent agency known as
the Tahal.
As its first priority, Tahal
began collecting water from
every possible source. Along
Israel's 125-mile-long coast,
engineers dug 30 wells per
mile to trap 10 billion gal-
lons of fresh water annually
before it could seep out
under the sea. Planes reg-
ularly seed clouds with
silver iodide to encourage
rain, while kibutzniks and
farmers burn the chemical
in special generators on the
ground. The land and air at-
tacks on clouds have swol-
len rainfall by about 15 per-
cent.
Tahal distributes its
bounty through a system
of canals, pipes, tunnels
and wells. Each year it
channels close to 90 bil-
lion gallons of fresh
water across Israel. °
At Avdot, deep in the
Negev desert, ecologists
from Ben-Gurion Univer-
sity have refurbished a
2,000-year-old network of
dry riverbeds and stone-
lined conduits to direct the
runoff of rain from the hills

Modern
ensures that farmers use no
more water than their pro-
duce requires. Sprinklers
have given way to drip irri-
gation. Computers monitor
air temperature, humidity
and wind speed and adjust
the amount of water deliv-
ered to the roots of the crops.
In one test, a region that
had yielded 9.52 tons of me-
lons per acre using
sprinklers produced 17.2
tons with drip irrigation.
Genetic engineers have
also joined the battle to
preserve water. A minia-
ture peach tree developed
by government scientists
can be planted at the as-
tonishing density of 3,200
trees per acre (compared
with the normal 120). Be-
cause the trees grow so close
together, they can be drip-
irrigated and their fruit
harvested quickly.
Researchers have di-
vided all fruits and veg-
etables that are grown in
Israel into four
categories, according to
their tolerance for salt.
This allows' water mana-
gers to stretch scarce ir-
rigation water by mixing
fresh and brackish
supplies. New varieties of
cucumbers, tomatoes,
melons and peppers, de-
veloped by careful
cross-breeding, thrive in
water whose salt content
is five times greater than
normal.
