Agricultural Sector Strategy: A Shared Vision /
2011-2013
 Agriculture is an essential component of the Palestinian national, cultural,
economic and social fabric.
 The Ministry of Agriculture and other relevant institutions have prepared
several policies, strategies and plans for the development of agricultural
sector with certain visions and assumptions, which regrettably did not
materialize due to the continuous Israeli stubbornness and rigid position.
 This Strategy has been designed to respond to the PNA trends and
instructions on the preparation of a set of sectoral and cross-cutting
strategies as a primary approach to develop the 2011-13 Palestinian National
Plan (PNP)
The Agricultural Sector Vision
 The vision constitutes the frame work, the guide and the general objective which
the agricultural sector is targeting within the next stage. The agricultural priorities,
policies, plans and projects are derived from the vision which will be built on the
reality and status of the agricultural sector
Within this frame, the future vision for the Palestinian agriculture is:
 Sustainable and feasible agriculture, that is capable of achieving food security,
competitive in the local and foreign markets through an optimal use of resources
as part of comprehensive development, and cementing the bonds and sovereignty
of Palestinians over their land, there on towards building the state.
Policies targeting the effective and sustainable management of
agricultural resources throughout the Palestinian territory
 Sustainable use, increasing the area, reclaiming the land and sustainable use of
agricultural biodiversity:
 This policy aims to increase and green the area of agricultural land as well as to
construct agricultural roads in order to protect land against erosion or
deterioration and protect wildlife and agricultural biodiversity. This policy will
brought about by implementing the following interventions:
 Identify, classify and reclaim lands and enhance productivity
 Afforest government and privately-owned land
 Develop and rehabilitate rangelands
 Conserve and sustainably use agricultural biodiversity
SOWT analysis
Strengths Weaknesses
- Available public agricultural institutions, which
have been established in a relatively good manner,
along with a large-scale geographical coverage.
- Active NGOs and civil society organizations
- Availability of qualified staff in certain tasks
- Modem and comprehensive agricultural law
- Availability the basic structures and infrastructure
such as universities, community colleges, training
centres and research centres
- Diversified climate suitable for several
agricultural production systems
- Skilled and committed farmers to their land and to
farming
- Good experience in dealing with emergencies and
crises
- Availability of human resources with potential
capabilities
- Integral relations and positive cooperation
between private and public sectors in agriculture
- Low productivity and profitability attained from
agriculture, and weak efficiency of using the
resources and inputs
- High potential of being affected by climate change
and fluctuated prices
- Weak performance and inappropriate organization
structures, number of staff and functions in
addition to weak coordination between institutions
of the agricultural sector
- High profit margins of the merchants, especially
the Israelis
- Lack of a national umbrella for planning and
comprehensive supervision of the agricultural
sector, as well as weak participation in decision
making
- Weak service delivery system and provision of
agricultural inputs
- Weak agricultural education system
Opportunities Threats
- Arab and international sympathy and
support to the PNA and to the 13th
Government Programme Palestine: Ending
the Occupation and Establishing the State.
- Increasing awareness around the world and
amongst members of the donor community
of the significance of supporting agricultural
development
- Palestinian agricultural products have access
to Arab countries with an exemption from
customs fees
- Sympathy and support to
Palestinians/products of the in external
markets.
- Commercial agreements concluded with
states, Arab and international entities.
- High potential for agri-tourism
- Israeli reactions that aim to dismantle the
plan of ending the occupation and
establishing the State as well as to
undermine the security and political
situations
- Continued policies of land confiscation,
seizure of water sources, wall construction,
settlement activity and division of the
Palestinian territory
- Limited budgetary appropriations for
agriculture
- Lack of land use plans and regulations
- Flooding the local markets with Israeli and
settlements’ products; restricted movement
of individuals, services and commerce
- High costs of inputs
- Increased and recurrent years of drought
Water resources
 Water available for agriculture amounts to 150 million cubic metres (mcm)
per annum, and constitute, 45% of the total water used distributed to 70
mcm in the West Bank and 80 mcm in the Gaza Strip. Ground water wells
are the main water source for irrigation in the Gaza Strip. In the West Bank,
irrigation water is supplied by groundwater wells and springs, and Israel
confiscates 82% of Palestinian ground water in the West Bank. The 2009
World Bank report on Palestinian water sources indicates that removal of
Israeli restrictions and provision of additional water quantities will raise
agricultural sector’s contribution to the Gross Domestic Product (GDP) by
10% and will create approximately 110,000 additional job opportunities
Land resources
 The cultivated area is estimated at 1.854 million dunums, or 31% of the total
area of the WBGS out of which 91% in the West Bank and 9% in the Gaza
Strip. The rain-fed area constitutes 86% while the irrigated area constitutes
14% of the total cultivated land, the rangeland amounts to 2.02 million
dunums. However, the area available for grazing is only 621 thousand
dunums. In addition, forests stretch over an area of 94 thousand dunums.
Historical Overview
The soils of Palestine have been the subject of many studies since the beginning
of the last century.
- The first soil survey was made in 1927-28 by Strahorn from the American
Bureau of Soils. He surveyed almost 4.9 million dunums of the low-lands of
Palestine. Maps at a scale of 1:40,000 and 1:63,000 were used in the field, and
the data were then assembled on a 1:250,000 map.
- Zohary (1942) studied the relations between vegetation and the various soil
formations, and based upon field reconnaissance observations he published a
generalized soil map at a scale of 1:600,000. He defined 11 soil types and
introduced the Rendzina group into the local nomenclature.
Reifenberg and Whittles (1947) studied in details the chemical properties of most
soil types occurring in Palestine, and compared their composition to that of
subjacent rocks. They published a schematic soil map at a scale of 1:1.6 million,
which relies heavily on the geological map.
- Rosensaft and Gil (1955) through the USDA Soil Conservation Service
published a soil type map at scale of 1:500,000 on which 13 soil types were
distinguished.
- Dan et al. (1962) described the soils and mapped them on the basis of soil
associations. A map having a scale of 1:250,000 was prepared. There are 17 soil
associations included in this map.
- Dan et al. (1976) reclassified and mapped again the soils of Palestine. They used
the physical properties as a basis for their classification and divided the soils into
34 units accompanied in 20 soil associations. In 1976 they published a soil map
at scale of 1:500,000.

Land Use
 Updated land cover and land use map
produced jointly between MoA and
MoP 2008
 It contains 37 different classes
•Map of Valuable agricultural land
was produced jointly by MoA and
MOPIC 1998
--Land was classified into three main
categories according to land
productivity value
highly value
moderate value
low value
--Updating this map will start soon
under the project of National spatial
planning
Under National spatial
planning Project,(on going
project) all stakeholders
agree to divide the
agricultural land into three
categories ,Highly protected
area
medium protected
and low protected area
depending on several
parameters
2010 MoA and LRC
were classified land
according to suitability
for reclamation into 3
categories
--Land suitable for

Environmental Problems Related to Soils
 Almost all types of soil erosion
are taking place in the West
Bank and all these types are
accelerated by human activities.
Recently soil erosion risk map
under publishing for 6 scattered
sites implemented by MoA and
LRC und Brazilian project
(ongoing project )
 based on the methodology
implemented in COoRdination
of Information on the
Environment (CORINE) model.
Soil Erosion
Soil erosion risk maps
in small selected area
in west bank
conducted by LRC in
the area of
northeastern heights
The lacustrine parent material in
Jordan Valley is an important
source of soil salinity in this area
In addition to other resources like
using saline water in irrigation and
miss management
Salt affected soil and saline soil are
widespread along Jordan valley.
Salinity survey and management are
now conducting on small area

• but in the MOCS soil salinity in 2006 was the
same 20-22ms/cm and in 2007
Significant decreasing in the salinity were
noticed the range was 7-13
• In 2008 the range was 13-15 ms/cm
after completion no available data in 2006
• but comparing between 2007 & 2008
slight deference in Ec in the second and third
layers but in the surface Layer a big deference
was noticed between 2007 & 2008

Soil Contamination
Pesticides and Insecticides
There are several causes for soil contamination
in the West Bank. Pesticides and insecticides
are the main soil contaminant in irrigated areas
Total irrigated area about 870 000 dunum
Unfortunately some of the used pesticides are
internationally forbidden.
Excessive Use of Fertilizers
The excessive and uncontrolled
use of fertilizers is another
source of contamination for
both soil and groundwater. It
is considered one of the salinity
resources in the soil and to
ground water.
Soil Sealing
 The rate of soil loss due to surface sealing is relatively high in Palestine.
Urbanization and transport infrastructure is rapid either by Palestinians or the
expansion and establishment of Israeli colonies and confiscation of land.
 In the eastern parts of the West Bank, livestock have to be herded for long
distances in search of water and suitable pasture, resulting in serious trampling
due to the increased traffic by animals.
Decline of Soil Fertility
 The above mentioned pressures in addition to other factors as the uncontrolled
fertilizers application clearly lead to the decline in organic matter, loss of nutrient
elements and an increase in toxicity scale.
 There are no systematic recording of soil fertility parameters that would help in
evaluating the fertility status with time of soils in the West Bank and Gaza Strip.
 However, agricultural productivity in many areas indicates the degradation in soil
fertility.
Reduction of Vegetation Cover
 Although forest area in the West Bank is very small (about 4900 ha - <1%), it is
estimated that 23% of the forest area has been destroyed from 1971 to 1999. The
majority of this destruction has been caused by the construction of Israeli colonies and
military camps.
 Rangeland and natural grassland are also negatively affected in the last three
decades due to the political situation. The limitation of the access to Palestinian herds
resulted in intensive grazing to the remaining small area that is estimated to be about
15% of the whole rangeland area.
Loss of Biodiversity
Almost all the distinguished ecosystems in Palestine are under one type or
another type of driving forces for biodiversity loss. For example, the Jordan
Valley ecosystem comprising the Dead Sea is clearly threatened in terms of
biodiversity loss due to land degradation.
Developing soil data base
 Structure on access form of soil data base was established in the ministry of
agriculture
 These data base consist of 3 main parts
 Site description parameters
 Soil profile description parameters
 soil profile –water- relationship parameters
The current GIS at the Palestinian MoA
1. Digitized Land system
2. Producing Land Use/Cover.
3. Detailed soil characteristics profile surveying data.
4. Digitized soil association map and soil type map.
5. Soil survey at different locations and different scales.
6. Digital Terrain Model derived thematic map like slope, aspect and
elevation.
7. Land capability and suitability maps for several locations at large scale
8. Soil salinity maps for different location at large scale
Actions Needed
The following are suggested actions that should be conducted to reduce soil
degradation at the political/institutional and technical levels:
Adopting a strategic plan for land use at the country level;
Activating the UNCCD national committee to take its responsibility of developing
strategic framework and policy for combating desertification in Palestine;
Improve administration, policy and plans of national institutions, human
resources, research and scientific capabilities;
Continue and intensify adopting and supervising the activities of land
reclamation and soil conservation on new solid bases;
Encourage, facilitate and provide capabilities for applied research related to
soil degradation;
 Creating unified soil database at the national and regional levels.
Utilization of household organic wastes and crop residues as fertilizer
(composting) for selected crops in the farm or garden.
NGOs and research institutions should develop technical solutions to practical
problems facing farmers as fluctuating soil salinity, proper soil tillage practices,
etc. This should be combined with public awareness campaigns and extension
programs for farmers. This means also promoting the involvement of local
people in data collection and identifying the technical problems facing them in
the field.

  • 1. THE SOILS OF PALESTINE: CURRENT STATUS AND FUTURE TRENDS Prepared by Imad Ghanma Ministry of Agriculture General Directorate of soil and irrigation
  • 2. 23 October 2012 2 500 km2 3350km2 1300km2 506km2 360km2
  • 3. Agricultural Sector Strategy: A Shared Vision / 2011-2013  Agriculture is an essential component of the Palestinian national, cultural, economic and social fabric.  The Ministry of Agriculture and other relevant institutions have prepared several policies, strategies and plans for the development of agricultural sector with certain visions and assumptions, which regrettably did not materialize due to the continuous Israeli stubbornness and rigid position.  This Strategy has been designed to respond to the PNA trends and instructions on the preparation of a set of sectoral and cross-cutting strategies as a primary approach to develop the 2011-13 Palestinian National Plan (PNP)
  • 4. The Agricultural Sector Vision  The vision constitutes the frame work, the guide and the general objective which the agricultural sector is targeting within the next stage. The agricultural priorities, policies, plans and projects are derived from the vision which will be built on the reality and status of the agricultural sector Within this frame, the future vision for the Palestinian agriculture is:  Sustainable and feasible agriculture, that is capable of achieving food security, competitive in the local and foreign markets through an optimal use of resources as part of comprehensive development, and cementing the bonds and sovereignty of Palestinians over their land, there on towards building the state.
  • 5. Policies targeting the effective and sustainable management of agricultural resources throughout the Palestinian territory  Sustainable use, increasing the area, reclaiming the land and sustainable use of agricultural biodiversity:  This policy aims to increase and green the area of agricultural land as well as to construct agricultural roads in order to protect land against erosion or deterioration and protect wildlife and agricultural biodiversity. This policy will brought about by implementing the following interventions:  Identify, classify and reclaim lands and enhance productivity  Afforest government and privately-owned land  Develop and rehabilitate rangelands  Conserve and sustainably use agricultural biodiversity
  • 6. SOWT analysis Strengths Weaknesses - Available public agricultural institutions, which have been established in a relatively good manner, along with a large-scale geographical coverage. - Active NGOs and civil society organizations - Availability of qualified staff in certain tasks - Modem and comprehensive agricultural law - Availability the basic structures and infrastructure such as universities, community colleges, training centres and research centres - Diversified climate suitable for several agricultural production systems - Skilled and committed farmers to their land and to farming - Good experience in dealing with emergencies and crises - Availability of human resources with potential capabilities - Integral relations and positive cooperation between private and public sectors in agriculture - Low productivity and profitability attained from agriculture, and weak efficiency of using the resources and inputs - High potential of being affected by climate change and fluctuated prices - Weak performance and inappropriate organization structures, number of staff and functions in addition to weak coordination between institutions of the agricultural sector - High profit margins of the merchants, especially the Israelis - Lack of a national umbrella for planning and comprehensive supervision of the agricultural sector, as well as weak participation in decision making - Weak service delivery system and provision of agricultural inputs - Weak agricultural education system
  • 7. Opportunities Threats - Arab and international sympathy and support to the PNA and to the 13th Government Programme Palestine: Ending the Occupation and Establishing the State. - Increasing awareness around the world and amongst members of the donor community of the significance of supporting agricultural development - Palestinian agricultural products have access to Arab countries with an exemption from customs fees - Sympathy and support to Palestinians/products of the in external markets. - Commercial agreements concluded with states, Arab and international entities. - High potential for agri-tourism - Israeli reactions that aim to dismantle the plan of ending the occupation and establishing the State as well as to undermine the security and political situations - Continued policies of land confiscation, seizure of water sources, wall construction, settlement activity and division of the Palestinian territory - Limited budgetary appropriations for agriculture - Lack of land use plans and regulations - Flooding the local markets with Israeli and settlements’ products; restricted movement of individuals, services and commerce - High costs of inputs - Increased and recurrent years of drought
  • 8. Water resources  Water available for agriculture amounts to 150 million cubic metres (mcm) per annum, and constitute, 45% of the total water used distributed to 70 mcm in the West Bank and 80 mcm in the Gaza Strip. Ground water wells are the main water source for irrigation in the Gaza Strip. In the West Bank, irrigation water is supplied by groundwater wells and springs, and Israel confiscates 82% of Palestinian ground water in the West Bank. The 2009 World Bank report on Palestinian water sources indicates that removal of Israeli restrictions and provision of additional water quantities will raise agricultural sector’s contribution to the Gross Domestic Product (GDP) by 10% and will create approximately 110,000 additional job opportunities
  • 9. Land resources  The cultivated area is estimated at 1.854 million dunums, or 31% of the total area of the WBGS out of which 91% in the West Bank and 9% in the Gaza Strip. The rain-fed area constitutes 86% while the irrigated area constitutes 14% of the total cultivated land, the rangeland amounts to 2.02 million dunums. However, the area available for grazing is only 621 thousand dunums. In addition, forests stretch over an area of 94 thousand dunums.
  • 10. Historical Overview The soils of Palestine have been the subject of many studies since the beginning of the last century. - The first soil survey was made in 1927-28 by Strahorn from the American Bureau of Soils. He surveyed almost 4.9 million dunums of the low-lands of Palestine. Maps at a scale of 1:40,000 and 1:63,000 were used in the field, and the data were then assembled on a 1:250,000 map. - Zohary (1942) studied the relations between vegetation and the various soil formations, and based upon field reconnaissance observations he published a generalized soil map at a scale of 1:600,000. He defined 11 soil types and introduced the Rendzina group into the local nomenclature.
  • 11. Reifenberg and Whittles (1947) studied in details the chemical properties of most soil types occurring in Palestine, and compared their composition to that of subjacent rocks. They published a schematic soil map at a scale of 1:1.6 million, which relies heavily on the geological map. - Rosensaft and Gil (1955) through the USDA Soil Conservation Service published a soil type map at scale of 1:500,000 on which 13 soil types were distinguished.
  • 12. - Dan et al. (1962) described the soils and mapped them on the basis of soil associations. A map having a scale of 1:250,000 was prepared. There are 17 soil associations included in this map. - Dan et al. (1976) reclassified and mapped again the soils of Palestine. They used the physical properties as a basis for their classification and divided the soils into 34 units accompanied in 20 soil associations. In 1976 they published a soil map at scale of 1:500,000.

  • 31. Soil Contamination Pesticides and Insecticides There are several causes for soil contamination in the West Bank. Pesticides and insecticides are the main soil contaminant in irrigated areas Total irrigated area about 870 000 dunum Unfortunately some of the used pesticides are internationally forbidden.
  • 32. Excessive Use of Fertilizers The excessive and uncontrolled use of fertilizers is another source of contamination for both soil and groundwater. It is considered one of the salinity resources in the soil and to ground water.
  • 33. Soil Sealing  The rate of soil loss due to surface sealing is relatively high in Palestine. Urbanization and transport infrastructure is rapid either by Palestinians or the expansion and establishment of Israeli colonies and confiscation of land.  In the eastern parts of the West Bank, livestock have to be herded for long distances in search of water and suitable pasture, resulting in serious trampling due to the increased traffic by animals.
  • 34. Decline of Soil Fertility  The above mentioned pressures in addition to other factors as the uncontrolled fertilizers application clearly lead to the decline in organic matter, loss of nutrient elements and an increase in toxicity scale.  There are no systematic recording of soil fertility parameters that would help in evaluating the fertility status with time of soils in the West Bank and Gaza Strip.  However, agricultural productivity in many areas indicates the degradation in soil fertility.
  • 35. Reduction of Vegetation Cover  Although forest area in the West Bank is very small (about 4900 ha - <1%), it is estimated that 23% of the forest area has been destroyed from 1971 to 1999. The majority of this destruction has been caused by the construction of Israeli colonies and military camps.  Rangeland and natural grassland are also negatively affected in the last three decades due to the political situation. The limitation of the access to Palestinian herds resulted in intensive grazing to the remaining small area that is estimated to be about 15% of the whole rangeland area.
  • 36. Loss of Biodiversity Almost all the distinguished ecosystems in Palestine are under one type or another type of driving forces for biodiversity loss. For example, the Jordan Valley ecosystem comprising the Dead Sea is clearly threatened in terms of biodiversity loss due to land degradation.
  • 37. Developing soil data base  Structure on access form of soil data base was established in the ministry of agriculture  These data base consist of 3 main parts  Site description parameters  Soil profile description parameters  soil profile –water- relationship parameters
  • 38. The current GIS at the Palestinian MoA 1. Digitized Land system 2. Producing Land Use/Cover. 3. Detailed soil characteristics profile surveying data. 4. Digitized soil association map and soil type map. 5. Soil survey at different locations and different scales. 6. Digital Terrain Model derived thematic map like slope, aspect and elevation. 7. Land capability and suitability maps for several locations at large scale 8. Soil salinity maps for different location at large scale
  • 39. Actions Needed The following are suggested actions that should be conducted to reduce soil degradation at the political/institutional and technical levels: Adopting a strategic plan for land use at the country level; Activating the UNCCD national committee to take its responsibility of developing strategic framework and policy for combating desertification in Palestine; Improve administration, policy and plans of national institutions, human resources, research and scientific capabilities;
  • 40. Continue and intensify adopting and supervising the activities of land reclamation and soil conservation on new solid bases; Encourage, facilitate and provide capabilities for applied research related to soil degradation;  Creating unified soil database at the national and regional levels. Utilization of household organic wastes and crop residues as fertilizer (composting) for selected crops in the farm or garden.
  • 41. NGOs and research institutions should develop technical solutions to practical problems facing farmers as fluctuating soil salinity, proper soil tillage practices, etc. This should be combined with public awareness campaigns and extension programs for farmers. This means also promoting the involvement of local people in data collection and identifying the technical problems facing them in the field.
