Israel’s practices for 40 km
combating desertification 700
1. Study the natural Dry subhumid
N
potential of your Mediterranean
country’s ecosystems scrublands
32o
Israel has different types of
dryland ecosystems 500
Asian steppes
300
Their sensitivity to Semi arid
desertification increases
with their aridity 100 Arid
Sahara-Arabian
deserts
Hyper arid
2. Gain experience in 50
combating desertification 30o
by developing less 22,145 km2
sensitive dryland first
3. Major experience gained from exploring agriculture
dependent on low quality and unpredictably variable
quantities of local water resources – sustainability of
dryland agricultural development requires
transported water of high quality and stable quantities
30% of Israel water pumped from a lake managed as
operational reservoir from –220 m b.s.l. to 150 m a.s.l.
and transported along 300 km; these large quantities of
high quality water enable:
Rangeland Cropland
Year-round irrigation
Year-round cover
Leaching
No salinization No soil erosion
4. Coupling water transportation with water
conservation - increase water use efficiency
Irrigation practices Reduces:
Surface 45% • evaporation losses
Sprinklers 75% • fertilizer use
Drip 95% • herbicide use
• risks of salt damage
• health risks of wastewater

5. Rather than fight the desert curses, uncover and exploit the
desert’s blessings, for making dryland products competitive
Curse to blessing: Benefits:
• Solar radiation – • Low water use
much light • Low pesticide use
warm winters • Low land use
• Fossil water, brackish • CO2 fertilization
Used for:
Cash crops
Fruits & vegetables
Ornamental
Spices
Aquaculture
Fish
Algae Contributors to productivity:
Shrimps Agrotechnology, Mechanization,
Research, Extension …………….. 96%
Land and Water ………………… 4%
Protected Dryland Agriculture - Greenhouses
6. Dryland-adapted afforestation of rangelands (“Savannization”)
is a multi-purpose tool for combating desertification
200
150 mm
Runoff harvesting –
additional 35%
of annual rainfall
Afforestation (not reforestation) of a semi-arid dryland
7. “Savannization” promotes pastoralism and tourism
Water-harvesting landscaping
Planted trees
Soil conservation
Firewood production
Flood control
Increased soil moisture Recreation &
ecotourism
Promoted biodiversity
Higher forage quality
Fire management by controlled
grazing
8. Synergies between afforestation and agriculture
•Protected agriculture
•Afforestation
combined
•Save water
•Generate new water
•Afforestation
•Irrigated agriculture
In the semi-arid region
reduced surface reflectance
10-25% increase in
diurnal rains
9. Re-use of wastewater and combating desertification
In Dry subhumid
• Population Growth
• Increased standard of life
Increase water demand Urban sprawl
for domestic use
Less land
Less water
Dry subhumid agriculture
More wastewater 110Mm3

10. Use of sludge – experimental application to semi-
arid wheat fields
•Increase in yield – 34-38%
•Increase in soil concentration of nutrients
•Increase in soil concentration of heavy metals
11. Cooperate with neighboring countries on common
standards for re-use of treated wastewater and
application of sludge, to promote future export
and import of dryland agricultural products
October 2002 meeting of Israel, PA, Jordan, Egypt and
Tunisia in Grenada, Spain, on these standards (under the
project “Regional Initiative for Dryland Management”)
