Case Study of Israel

Presented to the

Committee for the Review

of the Implementation of the Convention (CRIC1)

Rome, Italy, 13 November 2002

Prepared by

Blaustein Institute for Desert Research

Sede Boqer Campus

Ben-Gurion University of the Negev

for the

Department of International Organizations

The Ministry of Foreign Affairs, State of Israel

1 November 2002

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

360Mm3 Mediterranean

Semiarid agriculture Pollution

Orchards Treatment

(Barcelona

250Mm3 Convention)

Salinization risk Sludge

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”)
