Irrigation in Ethiopia.Is it really small,medium & large?
IRRIGATION CATEGORIES /CLASSIFICATION/ IN ETHIOPIA
1. Categories of irrigation schemes:
In
the Ethiopian context, the irrigation sub-sector was conventionally
classified as small (less than 200ha), medium (200 to 3000ha) and
large-scale (over 3000ha) schemes in the early years of its emergence.
It refers only to size of land and ignores the ownership type, scales of capital,
knowledge and technology involved. This customary arrangement was opted
for its simplicity ,as then the large scale farms were either private
company or public owned and the small scale farms were that of
farmers(private or communal). However, that situation is consistently
eroding as small scale, high capital, and knowledge intensive farms by
private companies emerged; and farmers holdings started to shoot up.
Furthermore, the scale of the finance, technology and management which
were disguised require attention to determine the optimum coordination
and management.
The other major problem is when you ,for example, present the total irrigated land area in the country per regional states as a basis for further planning and funding.the reason is as follows.In the regional states like Oromia, Afar, and the SNNP Region where farmers were either forcefully evicted/or denied their communal/group/ and private water and land rights for public enterprises, private farms , and in the periods state farms were further established and expanded (during the 'Derg' regime) the amount of irrigated commands have relatively soared.
However the the share/%/ of the actual irrigated land areas owned and managed by farmers,and the benefits the local population got was insignificant.As a result,When these values are put against the regional states it conceals the facts on the ground, and so presents as though the populations of the regions have benefited from irrigation , and wittingly implies priority of planning and funding for other regions.
In order to overcome, this lump sum approach and investigate the concealed facts of ownership, scale of investment, and knowledge in the Oromia region, Ligdi (2003) used an alternative approach which was also very common in other countries and the region. This recommendation was opted for and presented as follows.

Irrigated Agriculture is categorized into 3 major categories (Ligdi, 2003)
1. Communal Small Holder Irrigation Schemes
These
small holder schemes are are constructed and developed by self –help or
through projects with External inputs by Governments and NGO’S and
Participation of Farmers. They are usually communal and managed by the
small holder farmers themselves.
These Communal smallholder schemes Comprise of
a. the traditional communal Irrigation Schemes (usually termed as Traditional Schemes) and;
b. the Improved /”Modern”/ Communal Schemes mostly termed as Modern Small Scale Irrigation Schemes, SSIS
2. Private /Commercial/ Irrigation Schemes
These
schemes are constructed, owned, and managed by enterpreuners,
individual investors (Smallholder farmers), or small or large commercial
companies
3. Public Irrigation Schemes
These
are mostly medium and large scale schemes developed/nationalized/,
owned and managed by the government as commercial farms producing for
export to generate foreign currency, create employment opportunities,
etc..
Figure : Irrigated land area in the different categories in Ethiopia
1.1 Communal Small Holder Irrigation Schemes
General (Major) features
These
small holder schemes are dominated by self –help irrigation and Water
undertakings based solely on local knowledge and skills with no or a
very Low External inputs as the case is in traditional irrigation;
and also includes the projects developed through External inputs by
Governments and NGO’S and Participation of Farmers, and termed as Improved Small scale Irrigation, SSI schemes ,
Both
the Traditional and Improved schemes are usually managed by the farmers
themselves, through appropriately organized farmers user groups termed
as Irrigation Water Users Associations, WUA’S.
Initial costs of small holder irrigation schemes are small, and O&M costs are relatively low.
1.1.1 Traditional irrigation schemes:
Specific Features
- These schemes are constructed under self-help program carried out by farmers on their own initiative and and in general each scheme vary from less than 50 to 100 ha.
- The total irrigated area is estimated to be about 138,000 ha and about 572,000 farmers are involved.
- Traditional water committees, locally known as ‘water fathers’, administer the water distribution and coordinate the maintenance activities of the schemes.
- Traditional irrigation is also very common in peri-urban areas, particularly in Addis Ababa and Bahir Dar, for the production of vegetables for the local market.
- The major drawback of traditional irrigation schemes is related to unstable headworks and faulty systems of irrigation stemming from lack of technology and knowledge.
- Simple and mostly temporary.
- The total area irrigated under traditional irrigation as complied from master plan studies & reports of the regions is estimated to be about 64,000 ha
1.1.2 Improved /Modern/ communal irrigation schemes (Generally termed as Modern small-scale irrigation schemes, SSIS)
These
schemes use technologies for irrigating up to 200 ha and are
constructed by the government/NGOs with farmer participation. (Range- 20
ha to 200 ha)
Specific Features
They are generally based on direct river diversions but they may also involve micro-dams for storage.
Example OROMIA
The
Evaluation study (OIDA, 2ooo) also disclosed that rivers are the main
water resource for the irrigation schemes in Oromia Region. Out of the
96 schemes, 72 schemes obtain water from rivers. The intake facilities
are represented by diversion weirs. Among 96 irrigation schemes, 67
schemes are run-of -river type with diversion weirs, while pumping
irrigation is operated to the limited extent.
The area equipped for irrigation in 2002 was about 48 300 ha and about 74 100 farmers were involved.
The
operation and maintenance of the schemes are the responsibility of the
water users, supported by the regional authorities/bureaus in charge of
irrigation development and management.
Water
Users Associations (WUAs) are formally established in some schemes but
traditional water management dominates in most of the modern schemes.
1.2 Private /Commercial/ Irrigation Schemes (Usually termed as Modern private irrigation Schemes):
These
schemes are constructed, owned, and managed by entrepreneurs,
individual investors (Smallholder farmers),or small or large commercial
companies
- Virtually all the early commercial farms in the 1960’s and the irrigated state farms were privately owned farms until nationalization of the rural lands/private property/ through in the mid 1970s.
- Some of these schemes were initially privately owned until later nationalized in coming to power of a socialist government and then returned by back to through privatization after disowning/abandonment
- Private investment in irrigation has recently re-emerged with the adoption of a market-based economy policy in the early 1980s.
- According Ethiopian Investment Authority 18 modern private irrigation projects are now operational.
- Accordingly, at the end of 2000, private investors had developed about 5 500 ha of irrigated farms, distributed in Afar (37 percent), Oromia (48 percent) and the Southern Nations, Nationalities and People’s Region (SNNPR) also known as the Southern Region (15 percent).
- Built and operated by entrepreneurs, these schemes may range in size a few hectares to several thousand hectares,
- Depend on low- lift pumping or run-of river diversion for irrigation water abstraction.
1.3. Public Irrigation Schemes
- These schemes comprise medium- and large-scale irrigation schemes with areas of 200-3 000 ha and above 3 000 ha respectively and a total estimated area of about 97 700 ha.
- They are constructed, owned and operated by public enterprises. These schemes are concentrated along the Awash River Course and were constructed in the 1960s-70s as either private farms or joint ventures.
- No such schemes have been developed for the last 7-8 years up to 2004.
- They constitute an area of about 61,000 ha
- 75% of the total is found in the Awash valley, the Blue Nile and the Wabe Shebele river basins
- Masonry weirs\ in some cases pump is used to abstract irrigation water.
- Conveyance & Operation is through open gravity canals.
- Furrow irrigation scheme is the norm from water application, except in case of Fincaa sugar estate where sprinkler is used.
- Irrigation efficiency is low (Aswash), 40% (adequate land leveling, water control & water measuring devices).
About
62 percent of the area equipped for irrigation is located in the Rift
Valley, while 29 percent of the area equipped for irrigation is located
in the Nile basin. The remaining 9 percent is located in the
Shebelli-Juba basin.
Region-wise,
about 39 percent of the irrigated area is in Oromia in central
Ethiopia, followed by 24 percent in Amhara in the north, 15 percent in
Afar in the northeast and 12 percent in SNNPR, while the remaining 10
percent is in the other regions. Nearly 100 percent of the irrigated
land is supplied from surface water, while groundwater use has just been
started on a pilot scale in East Amhara. Sprinkler irrigation is
practiced on about 2 percent of the irrigated area for sugar cane
production by government enterprises, while localized irrigation has
recently started in the Tigray and Amhara regions. Pump irrigation by a
group of farm households and private farms is practiced in some areas,
while human-powered (treadle pump) irrigation has also recently started
in the Tigray and Amhara regions. Though quantitative information is not
available, spate irrigation and flood recession cropping are practiced
in the lowland areas of the country, particularly in Dire Dawa, Somali,
East Amhara, and Tigray in the eastern and northeastern parts of the
country.

Jimma-'Haadha Kormaa'
After each night, and deep sleep
in the nostalgia for coffee:
Jimma-'Haadha Kormaa'
After each night, and deep sleep
In own room, across the street or in
a shop
When asking for the ‘winning brew’,
that restorative elixir
What do we feel?
Whom do we aspire to cheer?
Whom do we aspire to cheer?
In craving for the black potion to surpass our vertigo
To let it go…
Where do we go?
To the kitchen, to make that magic
in a pot, or
Walk to a usual spot, across the
street…
where we all meet,
somewhere quiet ...where we all sit……..
where we all meet,
somewhere quiet ...where we all sit……..
where we wait,
where a few wit , collude to cheat…?
In yearning for an uplift.
In yearning for an uplift.
With patience…..in good spirit
where do you go?
where do you go?
..... in that moment in dilemma
In yearning for an uplift,
invigorating aroma –
does it evoke .... the memory
of jimma????
Intuitively;
does it recall .. Jimma.....Gomma...
Intuitively;
does it recall .. Jimma.....Gomma...
In nostalgia of the cup – do you
remember 'coocee'…'kata mudagee', or jimma
Reminiscent of the concoction,
in account of the invention
do you acknowledge...the notion.
Jimma-Oromia was the origin..
.an african was that great geek who put the tech in motion
do you acknowledge...the notion.
Jimma-Oromia was the origin..
.an african was that great geek who put the tech in motion
Reminiscent of the blend—do you recall that kush legend
After each night, and deep sleep
Don’t we all have A long overdue
promise to keep?
In the morning, At coffee time
In the afternoon, with every dime
In each drink, and every seep
Don’t we all have a promise
to keep?
I think we do,
For the ethos.
With a token recollection, with a
mythos, trusteeship of memory-FOR POSTERITY
I think we do, for the honor,
principled integrity
In custody of the memory, in
posterity
..keeping alive the legend /mythlets have coffee
let's have wisdom'

1. INSTITUTIONAL DEVELOPMENT OF THE WATER SECTOR-Historical Overview*
Water
resources development approaches and organizations in Ethiopia have
evolved in to needs, as they were perceived over time. Before 1956,
only a small portion of Ethiopia’s water resources was developed and the
Government's administrative role was minimal. In 1956, a Water Resources Department
under the Ministry of Public Works & Communications was established
to handle a multi-purpose investigation of the Blue Nile Basin. Over
the years, it took on the river basin studies and water well drilling
programmes.
As a parallel development, the Awash Valley Authority in
1962 assumed responsibility for all water activities in the Awash
Valley (AVA). Its mandate includes all aspects of water planning,
development and operation including water rights administration.
In 1971, the growing importance of water elsewhere in Ethiopia was recognized by the establishment of the National Water Resources Commission (NWRC),
under the then Ministry of Public Works & Water Resources. The
Commission’s purposes and objectives covered the full range of water
responsibilities. The Commission’s powers were broad but were not fully
exercised and implemented due to financial and organizational
constraints as well as lack of commitment and willingness of public
authorities to accept a national authority over water resources
development and management. As a result, in 1975, the Ethiopian Water Resources Authority (EWRA)
was established and placed under the Ministry of Mines, Energy &
Water Resources. Three agencies, namely, Land & Water Studies
Agency, Rural Water Development Agency and Urban Water & Sewerage
Agency were established under the Authority. The AVA, however, retained
its responsibilities for the Awash Valley.
In another re-organizational undertaking, the Valleys Agricultural Development Authority (VADA)
was proclaimed in 1977. It had similar powers and duties as AVA except
that its jurisdiction was limited to water resources (AVA’s
responsibilities include all resources), but its authority covered the
whole country. To avoid conflict with AVA, the Awash Valley Development
Agency (AVDA), a creation of VADA was formed. The AVDA had diminished
powers as compared to those AVA had enjoyed.[1]
In 1981, a further re-organization took place in the water sector; and a new “National Water Resources Commission” (NWRC)
was created. VADA and AVDA were dissolved and incorporated in the
newly established NWRC under the Water Resources Development Authority
(WRDA). The new NWRC, in fact, was composed of the Water Resources
Authority, Water Supply and Sewerage Authority (WASSA), Ethiopian Water
Works Construction Authority (EWWCA); and the National Meteorological
Services (NMS).
After
about ten years of existence, the National Water Resources Commission
was dissolved and the Authorities under its umbrella, except EWWCA, were
made accountable to the Ministry of Natural Resources & Environmental Protection, which was established in 1993 and existed for about two years.
The Ministry of Water Resources
was established in August 1995 by proclamation No.4/95 as a federal
institution for the water sector. At regional level, the water sector
is the responsibility of the Water, Mines and Energy Development Bureaus
or the Water Resources Development Bureaus.
In the follow-up of the fall of the “Derg” regime, several
water sector institutions have been established at federal and regional
levels under the regionalization and decentralization policy.
2. OVERVIEW OF IRRIGATION DEVELOPMENT AND COORDINATION IN ETHIOPIA
Food
production in the country, with cereal yields of less than one t/ha has
failed to keep pace with population growth and in many areas; there are
increasing food deficits because of low rainfall or over-population.
Rain fed agriculture provides the largest proportion of the total
production. However, over the past few decades, irrigated agriculture
has become more important. River
basin master plan studies and related surveys indicate a maximum
irrigation potential of about 3.5 million ha (Table 6 ). However, the
irrigation potential of Ethiopia is at present estimated at about 2.7
million ha, considering the availability of water and land resources,
technology and finance.
2..1. Domains and Processes of Coordination
2.1.1 Historical Overview- The Ethiopian Experience in irrigation & Drainage Institutions
Even though, local traditional irrigation and drainage,
I&D coordination & management has been put in place for a very
long time and it is still going strong ,centralized institutional set
up to this end has been lacking for so long.
The
initial coordination &management of I&D as part of the overall
coordination and management of water resources stressed upon the
development and utilization of land and water resources of River Valleys
for agricultural development as indicated/stipulated from the early
institutional set-ups since the 1950'’.
As
a result ,it generally focused on administration & development of
large scale irrigation schemes for private companies and in later
stages for public enterprises, and/or may be for settlement programmes
effectively after the fall of the monarchy in 1974,and the subsequent
land reform decree, This is best justified by the nature of the
institutional set-ups in the 1950’s,60’s, and 70’s,
In
view of the recurrent droughts and famine and the abundant resource
potential (including water resources); absence of an overall I&D,
administrative body for Coordination and management of all categories of
Irrigation and Drainage, or that specifically set for the communal
small holder undertakings up until the disasters of 1984/5 is quite odd
and weird.
Nevertheless,
it is well known that the coping mechanisms of communities especially
in the moisture deficit lowland areas and their adjoining peripheries is
inadequate; and never prepared for curbing the effects of drought and
similar adversities
Yet,
smallholder irrigation development for farmers as a development
intervention strategy to fight the recurrent droughts and curtail the
resulting food shortages which occur following scarcity , failures, and
faltering of rainfall is a very recent phenomenon, which emerged through
the establishment of the Irrigation Development Department, IDD in the
Ministry of Agriculture, MOA following the disasters of 1984/5 droughts
and famines with a sole objective of promoting Small Scale Irrigation
Schemes, SSIS for farmers.
Furthermore,
with the federal government structure put in place subsequent to the
fall of the “Derg” regime, the above authority and responsibility of
promotion and coordination of SSIS was transferred to the respective
regional water ,or Natural Resources bureaux, or separate authorities
& commissions established for Irrigation or /and Sustainable
Agricultural development.
Nevertheless,
in most cases, the irrigation extension, cooperative and credit
institutions etc.. still remain to be coordinated under separate
institutions.
What's
more, a separate Federal institution , A Basin Water Resources
administration and management agency ,is being set up to coordinate,
administer, allocate and regulate the utilization of Surface water
resources of basins, For instance for Awash River Basin in 1998
(proclamation No.129/1998).
Similarly,
Studies for the establishment of other similar basin institutions, for
example the Abbay Basin Agency, ABA is underway
The
customary water rights embedded in the long years of traditional water
use, and ownership rights are further compounded by the practically
vague and intricate/ indistinct legal and institutional mandates and
responsibilities in place among the federal and regional states
To
this end, large water bodies, artificial storage structures and large
flow canals and natural waterways are continuously deteriorating, some
nearing points of no return.
2.1.2 Evolution of irrigation development
Irrigation
in Ethiopia dates back several centuries, if not millennia, even
though, commercial Irrigated agricultural development started in the
1960s with the objective of producing industrial crops (sugar and
cotton) on large-scale basis. These "modern" irrigation schemes started
with the commercial irrigated sugar estate established in the early
1950s by the Imperial Government of Ethiopia and the Dutch company known
as HVA-Ethiopia.
Based
up on the various river basin master plans and land and water resources
survey, the aggregate irrigation potential of Ethiopia (small, medium
and large) have been estimated 3.5 million hectares. Out of this
estimate the medium and large-scale irrigation potential together
comprises about 81.4% of the aggregate. From this potential only about
86,000 ha of land is currently developed under large-scale irrigation.
This implies that still there is a need to encourage the development of
large-scale schemes to alleviate poverty, prevail peace and stability in
the region and for better livelihood of the people and the economic
growth of the country.
Local
farmers however, had, for a very long time, already been practicing
rudimentary irrigation by diverting water from rivers( in the dry
season), Water (flood) harvesting and making use of shallow wells, for
the production of subsistence food and /or cash crops.
It is but evidently found that productivity of rain-fed farming has
dropped, and the agricultural sector is now unable to provide the basic
requirement to the farming community. Traditional farming practices,
environmental degradation, lack of external agro-inputs, effect of
recurrent drought, and high population pressure have aggravated the food
insecurity in Ethiopia. This implies the need of launching irrigation
projects development based on the acute objectives of increasing crop
yield, improving the living standard of the people and to provide a
positive impact on the environment.
Various
sources give different estimates of irrigated area, but recent sources
indicate that the area equipped for irrigation was nearly 290 000 ha in
2001, which is 11 percent of the economical irrigation potential of 2.7
million ha. This is about 7.8% of the usually quoted overall potential
of 3.7million hectares.

- Data on irrigated agriculture in Ethiopia is inadequate, of low quality and not comprehensive not to mention its inaccessibility. The sub-sector truly lacks an efficient and coordinated Knowledge management (Data Acquisition, storage and dissemination).
During
the same period a discussion paper on the Field Evaluation study on
Farmer’s Managed Small holder Irrigation Schemes in Oromia Regional
State reported that there are around 58,900ha.’s traditional and
18,100ha.’s improved schemes (About 116 schemes with about
12,500ha.’s by Government and 83 shemes amounting to about 5600ha.’s by
NGO’s and other institutions at the end of 2003). Whereas, for
example the EWWDSE (2000) reported only 10,000 hectares of modern
improved schemes for Oromia, probably reporting only that of the 96
schemes totaling 9644 hectares built by the government in the 2 decades
prior to 2000,.
(OIDA, 2000;Ligdi, 2000; Ligdi, 2003)
Furthermore, the data obtained from the anthology
of the Ministry of Water Resources, MoWR (Table 2)reveals similar
trends and shows that the amount of irrigated land in around 2000 is
over 200,000ha.’s and is by far more than the ones reported by EWWDSE,
2000.

Figure : Recent Trends in potentials created in Irrigation Development in Ethiopia
The
actually irrigated area has not been estimated but field assessments in
small-scale irrigation projects indicate that some irrigation schemes
are not operating to their full potential and some are not functional at
all due to factors related to shortage of water, damaged structures and
poor water management.
Example :OROMIA
The
small holders (farmers managed) improved small scale Irrigation schemes
evaluation study in 2000, reveals that in Oromia Region the
government constructed 96 irrigation schemes during the last two
decades. The total command area of the 96 schemes amounts to 9,644 ha's
giving an average of 100 ha's per scheme. It is noted that only 58% of
the area have been actually irrigated in that year ( i.e 2000 ) . This
low performance implies that all the schemes are not well functioning
and need urgent repairs & rectification. The scheme size ranges from
20 ha's to 1,500 ha's of the Meki - Ziway irrigation scheme.
Taking
land area actually developed Vs planned command area as performance
indicator, the study showed that only 56% of the schemes performed above
50% and 17 schemes were non-functional at the time. Furthermore about
11 shemes were performing above 100% some to up to 250% through
extension of canals and irrigating at a rate lower than the irrigation
depth and frequency the “modern” projects recommend through use of low stream sizes, long duration and irrigation applications under stress based on their local experiences
On
the other hand, therefore, farmers are extending canal networks in some
modern irrigation projects and can therefore irrigate more land than is
reportedly equipped for irrigation. Therefore, the area under
irrigation can be considered more or less similar to the area equipped
for irrigation.
Indicative Future Trends
The
Recent commitment and enthusiasm towards creation of more potentials
for irrigated agriculture is best shown in the PASDEP programme setting
out a 5 years I&D Development plan aspiring to bring about 435,000
hectares under irrigation (Table3)

2.2 Categories of irrigation schemes:
In
the Ethiopian context, the irrigation sub-sector was conventionally
classified as small (less than 200ha), medium (200 to 3000ha) and
large-scale (over 3000ha) schemes in the early years of its emergence.
It refers only to size of land and ignores the scales of capital,
knowledge and technology involved. This customary arrangement was opted
for its simplicity ,as then the large scale farms were either private
company or public owned and the small scale farms were that of
farmers(private or communal). However, that situation is consistently
eroding as small scale, high capital, and knowledge intensive farms by
private companies emerged; and farmers holdings started to shoot up.
Furthermore, the scale of the finance, technology and management which
were disguised require attention to determine the optimum coordination
and management.
In order to overcome, this lump sum approach and investigate the concealed facts of ownership scale of investment, and knowledge in the oromia region, Ligdi (2003) used an alternative approach which was also very common in other countries and the region. This recommendation was opted for and presented as follows.
Irrigated Agriculture is categorized into 3 major categories (Ligdi, 2003)
1. Communal Small Holder Irrigation Schemes
These
small holder schemes are are constructed and developed by self –help or
through projects with External inputs by Governments and NGO’S and
Participation of Farmers. They are usually communal and managed by the
small holder farmers themselves.
These Communal smallholder schemes Comprise of
a. the traditional communal Irrigation Schemes (usually termed as Traditional Schemes) and;
b. the Improved /”Modern”/ Communal Schemes mostly termed as Modern Small Scale Irrigation Schemes, SSIS
2. Private /Commercial/ Irrigation Schemes
These
schemes are constructed, owned, and managed by enterpreuners,
individual investors (Smallholder farmers), or small or large commercial
companies
3. Public Irrigation Schemes
These
are mostly medium and large scale schemes developed/nationalized/,
owned and managed by the government as commercial farms producing for
export to generate foreign currency, create employment opportunities,
etc..
Figure : Irrigated land area in the different categories in Ethiopia
2...2.1 Communal Small Holder Irrigation Schemes
General (Major) features
These
small holder schemes are dominated by self –help irrigation and Water
undertakings based solely on local knowledge and skills with no or a
very Low External inputs as the case is in traditional irrigation;
and also includes the projects developed through External inputs by
Governments and NGO’S and Participation of Farmers, and termed as Improved Small scale Irrigation, SSI schemes ,
Both
the Traditional and Improved schemes are usually managed by the farmers
themselves, through appropriately organized farmers user groups termed
as Irrigation Water Users Associations, WUA’S.
Initial costs of small holder irrigation schemes are small, and O&M costs are relatively low.
2.2.1.1 Traditional irrigation schemes:
Specific Features
- These schemes are constructed under self-help program carried out by farmers on their own initiative and and in general each scheme vary from less than 50 to 100 ha.
- The total irrigated area is estimated to be about 138,000 ha and about 572,000 farmers are involved.
- Traditional water committees, locally known as ‘water fathers’, administer the water distribution and coordinate the maintenance activities of the schemes.
- Traditional irrigation is also very common in peri-urban areas, particularly in Addis Ababa and Bahir Dar, for the production of vegetables for the local market.
- The major drawback of traditional irrigation schemes is related to unstable headworks and faulty systems of irrigation stemming from lack of technology and knowledge.
- Simple and mostly temporary.
- The total area irrigated under traditional irrigation as complied from master plan studies & reports of the regions is estimated to be about 64,000 ha
2.2.1.2 Improved /Modern/ communal irrigation schemes (Generally termed as Modern small-scale irrigation schemes, SSIS)
These
schemes use technologies for irrigating up to 200 ha and are
constructed by the government/NGOs with farmer participation. (Range- 20
ha to 200 ha)
Specific Features
They are generally based on direct river diversions but they may also involve micro-dams for storage.
Example OROMIA
The
Evaluation study (OIDA, 2ooo) also disclosed that rivers are the main
water resource for the irrigation schemes in Oromia Region. Out of the
96 schemes, 72 schemes obtain water from rivers. The intake facilities
are represented by diversion weirs. Among 96 irrigation schemes, 67
schemes are run-of -river type with diversion weirs, while pumping
irrigation is operated to the limited extent.
The area equipped for irrigation in 2002 was about 48 300 ha and about 74 100 farmers were involved.
The
operation and maintenance of the schemes are the responsibility of the
water users, supported by the regional authorities/bureaus in charge of
irrigation development and management.
Water
Users Associations (WUAs) are formally established in some schemes but
traditional water management dominates in most of the modern schemes.
1.2.2 Private /Commercial/ Irrigation Schemes (Usually termed as Modern private irrigation Schemes):
These
schemes are constructed, owned, and managed by entrepreneurs,
individual investors (Smallholder farmers),or small or large commercial
companies
- Virtually all the early commercial farms in the 1960’s and the irrigated state farms were privately owned farms until nationalization of the rural lands/private property/ through in the mid 1970s.
- Some of these schemes were initially privately owned until later nationalized in coming to power of a socialist government and then returned by back to through privatization after disowning/abandonment
- Private investment in irrigation has recently re-emerged with the adoption of a market-based economy policy in the early 1980s.
- According Ethiopian Investment Authority 18 modern private irrigation projects are now operational.
- Accordingly, at the end of 2000, private investors had developed about 5 500 ha of irrigated farms, distributed in Afar (37 percent), Oromia (48 percent) and the Southern Nations, Nationalities and People’s Region (SNNPR) also known as the Southern Region (15 percent).
- Built and operated by entrepreneurs, these schemes may range in size a few hectares to several thousand hectares,
- Depend on low- lift pumping or run-of river diversion for irrigation water abstraction.
2.2.3. Public Irrigation Schemes
- These schemes comprise medium- and large-scale irrigation schemes with areas of 200-3 000 ha and above 3 000 ha respectively and a total estimated area of about 97 700 ha.
- They are constructed, owned and operated by public enterprises. These schemes are concentrated along the Awash River Course and were constructed in the 1960s-70s as either private farms or joint ventures.
- No such schemes have been developed for the last 7-8 years.
- They constitute an area of about 61,000 ha
- 75% of the total is found in the Awash valley, the Blue Nile and the Wabe Shebele river basins
- Masonry weirs\ in some cases pump is used to abstract irrigation water.
- Conveyance & Operation is through open gravity canals.
- Furrow irrigation scheme is the norm from water application, except in case of Fincaa sugar estate where sprinkler is used.
- Irrigation efficiency is low (Aswash), 40% (adequate land leveling, water control & water measuring devices).
About
62 percent of the area equipped for irrigation is located in the Rift
Valley, while 29 percent of the area equipped for irrigation is located
in the Nile basin. The remaining 9 percent is located in the
Shebelli-Juba basin.
Region-wise,
about 39 percent of the irrigated area is in Oromia in central
Ethiopia, followed by 24 percent in Amhara in the north, 15 percent in
Afar in the northeast and 12 percent in SNNPR, while the remaining 10
percent is in the other regions. Nearly 100 percent of the irrigated
land is supplied from surface water, while groundwater use has just been
started on a pilot scale in East Amhara. Sprinkler irrigation is
practiced on about 2 percent of the irrigated area for sugar cane
production by government enterprises, while localized irrigation has
recently started in the Tigray and Amhara regions. Pump irrigation by a
group of farm households and private farms is practiced in some areas,
while human-powered (treadle pump) irrigation has also recently started
in the Tigray and Amhara regions. Though quantitative information is not
available, spate irrigation and flood recession cropping are practiced
in the lowland areas of the country, particularly in Dire Dawa, Somali,
East Amhara, and Tigray in the eastern and northeastern parts of the
country.
2.3 STATUS AND EVOLUTION OF DRAINAGE SYSTEMS
Drainage
is as important as irrigation, particularly in the highlands of
Ethiopia. However, except in irrigated lands, drainage is not given the
required attention in rainfed agriculture where farmers construct
traditional drain ditches commonly diagonal to the main slope of the
farmlands. Because of irregularity in cross-sections and longitudinal
slopes as well as inadequate capacities, the drains are usually
converted to gullies if the same drains are adopted year after year. To
avoid this happening, drain lines are changed every year. Designs of
small-scale irrigation schemes incorporate drainage systems but these
are not properly implemented. The typology of the drainage system used
in the country is the surface drainage system (gravity drainage). The
construction of subsurface drainage systems was started for one
large-scale irrigation scheme in the Awash Valley for salinity control,
but was discontinued. Separate information on the cost of drainage
systems is not available because it is included in the overall
development cost of the irrigation system.
Traditional Drainage Agriculture/Recession Agriculture/,
Traditional
Drainage agriculture (Recession Agriculture) using surface field
drainage ditches in valley bottoms and lowlying areas is adundant in
high rainfall areas. Wetlands surrounding water bodies (lakes, rivers,
springs,etc..) are also becoming under increased risks of degradation
through clearance for opening up new agricultural lands .
Albeit,
their appreciable contribution to the overall agricultural production
of the locality they are practised in ,and their practice and use in
the lean months of the rainfed agriculture; these traditional forms of
drainage agriculture are the least studied and supported.
even
though the recent agricultural food security packages programme has
incorporated them as an activity, their evaluation and understanding
remains open for investigation.
3. THE ROLE OF IRRIGATION & DRAINAGE IN AGRICULTURAL PRODUCTION, ECONOMY AND SOCIETY IN ETHIOPIA
3.1 General
Both
irrigated and rainfed agriculture is important in the Ethiopian
economy. Virtually all food crops in Ethiopia come from rainfed
agriculture with the irrigation sub-sector accounting for only about 3
percent of the food crops. Export crops such as coffee, oilseed and
pulses are also mostly rainfed, but industrial crops such as sugar cane,
cotton and fruit are irrigated. Other important irrigated crops include
vegetables and fruit trees in medium- and large-scale schemes and
maize, wheat, vegetables, potatoes, sweet potatoes and bananas in
small-scale schemes. There is a marked value added in irrigated
agriculture.
Development
costs per hectare of small-scale irrigation schemes are US$ 1760-2940
for direct river diversion schemes and US$ 4700-7100 for schemes
requiring micro-dams, while the respective annual operation and
maintenance (O&M) costs per hectare are US$ 70-120 and US$ 160-240
respectively. In 1998, development costs for public surface irrigation
schemes (large- and medium-scale) were estimated to be in the range of
US$ 3300-12800/ha, with the average cost being US$ 8100/ha. This high
cost is due to the fact that the construction of expensive head works is
included in the calculation. Annual O&M costs for these schemes are
US$ 60-220/ha. The cost of sprinkler and localized irrigation
installation is about US$ 5160/ha and US$ 5560/ha respectively.
The
proportion of traditionally irrigated land (almost half of the total
irrigated area) and the number of farmers involved indicate the
significant economic and social role of traditional irrigation for rural
society. Urban and peri-urban irrigation are not significant in terms
of area coverage and production, but the traditional irrigation practice
around Addis Ababa plays an important role in supplying vegetables for
the Addis Ababa market.
Supplementary
irrigation is widely practiced in all irrigation categories, although
separate quantitative information on the area supplied with
supplementary irrigation is not available. The areas under traditional
and small-scale irrigation systems are supplied with full irrigation
during dry periods and with supplementary irrigation when the rain comes
late or withdraws early, or when there is inadequate rainfall.
Rainfed
farming has always been the main livelihood for most Ethiopian people
and is supported by traditional water harvesting practices particularly
in central-north, eastern and southeastern areas of the country.
3.2. Irrigation & Drainage development; Water resources Management and Sustainable Growth.
The
effect of management of water resources (including irrigation
development) on the current and future sustainable economic growth of
Ethiopia is best explained by Claudia Seddof, a world bank economist in
her paper entitled ”Managing Water Resources To Maximise Sustainable Growth –A Water Resources Assistance Strategy for Ethiopia.”(The World Bank,2005).
The
paper focuses on understanding the dynamics of water in economy, (i.e
how to manage water to minimise destructive and enhance productive
impacts on the economy; and how to manage the economy to minimise the
impact of water shocks).
The Paper explains/summarises the challenges of the Ethiopia’s hydro-economy as follows:
Ethiopia’s
hydrological variability is extreme and this variability impacts the
entire economy whose structure makes it particularly vulnerable to
hydrologic variability and the water infrastructure is inadequate to
mitigate variability and enable growth.
Economic infrastructure
Figure :Water Infrastructure Development in Ethiopia, (world bank,2005)
Storage infrastructure
Figure: Per capita Storage Capacity of Some Countries. (World Bank, 2003)
Furthermore,
in an economy-wide multi-market model for Ethiopia (Standard model for
growth and poverty projection) modified to explicitly incorporate
hydrology.
The paper concluded that
1. Macro
economic models , that fail to take account of hydrological
variability, and which are often employed in Ethiopia, fail to show the
water’s “ drag ‘ on growth and hence over estimate growth and under
estimate poverty and undervalue returns to irrigation as irrigation
doesn’t pay well if rainfall is good-
2. Ethiopia
does not yet have the minimum plat form of infrastructure, institutions
and capacity to reach the tipping point of water security where net
impact of water on growth is positive.
In assessing alternative investments, the model showed that
1. Projected returns to irrigation investments increase as variability increase
[taking account of hydrology can more than double returns]
2. Synergies between irrigation and infrastructure investments increases as variability increases
As an insight for intervention the model recommends/ prioritizes, among others, that
Multi-purpose
hydraulic infrastructure development/ multi-purpose storage and river
regulation facilities [hydropower, irrigation and even roads ] to
promote economic resilience as a proposed strategy for the Bank support.
The
major insight of the model and the study as a whole were very
significant and imperative for the irrigation sub-sector which had been
tied up for so long with no visible positive impact on economy.
What
is crucial is that this is so in a country where recurrent droughts and
famine, and food insecurity claim millions of lives, now and then,,
despite the vast unexploited resources and growth opportunities
These fundamental and critical conclusions and recommendations, are summarized as follows:
Growth
will be undermined until water security is attained, it will require
very large investment to achieve a nation-wide minimum platform of water
infrastructure and management capacity
Economic wide models that fail to incorporate hydrological variability will be poor predictors of growth & poverty.
Current
structure of the economy & incentives trap farmers in highly
vulnerable rain fed subsistence agriculture-[hydrological resilience
will require structural change in the economy]
Multipurpose
hydraulic/hydropower infrastructure can promote economic resilience
both by directly regulating flows and by promoting structural shifts in
the economy
Returns
to irrigation and Drainage investments are systematically
underestimated in models that fail to capture hydrology because returns
to irrigation and drainage are highest in times of drought and flood
Multi-purpose
Hydraulic infrastructure development (including Multi-purpose storage
facilities for I& D) is proposed/recommended as a strategy for
maximising sustainable growth in Ethiopia
In
summary the study shows that the country’s economy is dependant on
hydrological variability and the only way out is to achieve/attain water
security through, among others, development of multipurpose water
infrastructure which will positively impact the economy and maximise
sustainable growth.
Therefore,
unless and until the minimum platform for water security is reached,
the country’s hydro-economy will continue to be vulnerable, inept and
incapable to enable real and sustainable growth.
