7Chronology of the Aral Sea disaster
- 1920s Decision to launch a program on
intensifying cotton production in the Aral Sea
basin. - Following decades Development of an immense
irrigation infrastructure. - 1960 Beginning of deterioration.
- Increasing amount of water used for irrigation
- low irrigation efficiency
- gt Dramatic loss of inflow into Aral Sea
8Percentage irrigated area of total land

Annual withdrawal from Syr Darya and Amu Darya of
12.900 m3 although only 4900 m3 are actually used
by the crops. The losses are mainly due to
seepage into the underground.
9Some facts about the Aral Sea Disaster
- 1960-2002
- - Original Aral Sea surface (68.000 km3) halved
- - Volume decreased by 80
- gt Aral Sea divided into two parts.
- Increase of salinity from 10 g/l up to 60 g/l.
- Collapse of the fishery industry and problems for
farmers. - Approximately 200.000 tons of salt and sand are
carried away and discharged in a radius of 300 km
every day. - Health of residents severely affected

142. Irrigation versus hydropower The Toktogul
Reservoir
15The Syr Darya Basin
16The Toktogul Reservoir
- Soviet regime design
- Most important reservoir at the Syr Darya with an
annual inflow of about 11.8 km3. - Constructed in 1974 to regulate the Syr Darya
flow during the vegetation period. - Additionally production of hydropower
- Releases during vegetation period 8.5 km3
- Releases during non-vegetation period 2.8 km3
17- How it changed after 1991.
- Kazakhstan and Uzbekistan soon introduced market
prices for their coal and gas. - Due to energy shortages Kyrgyzstan repeatedly had
to release 6-8 km3 water in winter. - Consequences for the downstream countries were
fatal - - Lack of irrigation water in summer
- - Floodings and water losses in winter due to
icy Syr Darya bed - gt Tensions grew
18The Barter Agreement of 1998 Kazakhstan
Uzbekistan Kyrgyzstan Tajikistan (1999)
- During the vegetation period Kyrgyzstan releases
more water than it needs for its own hydropower
demands. - The surplus of produced energy is equally
distributed and transported to Kazakhstan and
Uzbekistan. - As compensation, Uzbekistan and Kazakhstan supply
Kyrgyzstan with energy resources (coal and gas). - The exact amounts of water to be released and
compen- sations for energy losses are agreed
annually. - Any disputes or disagreements will be resolved
through negotiations and consultations.

20Success- failure
- What would have been the collective optimum
and what is in reality - 1. The downstream countries must receive enough
water during the vegetation period to meet their
irrigation demands (6 km3). - Success The actual average received water in
1999-2001 was 5.82 km3. - The annual agreements on the barter agreement
must be carried out in a regular,
uncomplicated, flexible and efficient way. - Success The annual negotiations have indeed
been carried out. - Failure Agreements are always reached
with a delay.
21Success- failure
- Kyrgyzstan is reliably and punctually compensated
for its energy losses due to the reduced water
releases in winter. - Failure The compensation payments to Kyrgyzstan
have never been caried out according to the
annual agreements. - Water releases during the non-vegetation period
must not exceed 6 km3 in order to prevent
flooding. - Failure Release of huge amounts of water during
the non-vegetation period (2000-2001 average was
8.4 km3) Un-sustainable management of Toktogul
reservoir - if operation continues in this way
the reservoir will reach its dead storage volume
in 2003!

23Influence of Non Regime Variables
- Asymmetries
- Young age of the countries
- State of economic development
- Scientific understanding
24Asymmetries
- Geographical and climatological factors.
- Upstream countries (Kyrgyzstan and Tajikistan)
are situated at higher altitudes and receive
higher precipitation rates. - -Kyrgyzstan covers 6 of the Syr Darya basin but
provides 75 of the water inflow. - Upstream countries contain mountainous areas
which enables them to build reservoirs to store
water and control the releases. - Powerful position for the upstream countries.
- .
25Asymmetries
- Political, economic and military strength.
- The political, economic and military strength is
much larger in the downstream countries compared
to the upstream ones. - -Uzbekistan Kazakhstan
- GDP 160 billion.
- Military expenses 373 million.
- -Kyrgyzstan Tajikistan
- GDP 21 billion.
- Military expenses 35 million.
- Powerful position for the downstream countries.
- Advantages of both sides are always balanced.
Both upstream and downstream countries depend on
each other. The barter agreement accounts for the
different needs of the two groups.
26Influence of Non Regime Variables
- Asymmetries
- Young age of the countries
- State of economic development
- Scientific understanding
27Young Age of the Countries
- Only in 1991 the USSR collapsed, new countries
arised and the main rivers became transboundary
rivers. - Consequences.
- Many water allocation regimes and rules are often
still based on the old ones prescribed by the
USSR. They fail to take into account the
individual perspectives of economic development
of the countries. - As the involved countries became independent only
a decade ago they are often fractioned and
politically unstable and still have not fully
realized the necessity to cooperate. - Due to the young age of the countries, the
debates over water are not only limited to water
stress but also comprise ethnic rivalries, border
disputes and other problems. - Strong negative effect on the barter agreement.
- The treaty probably evolved more due to the
asymmetry pressures than due to mutual respect.
28Influence of Non Regime Variables
- Asymmetries
- Young age of the countries
- State of economic development
- Scientific understanding
29State of Economic Development
- Bad economic and financial situation in the
downsteam countries that prevents them from
restoring their fragile infrastructure. - -Replacing outdated irrigation systems could do
much to reduce the water use. - -Due to broken pipelines Uzbekistan is regulary
not able to deliver gas to Kyrgyzstan. - Tense financial situation of Kyrgyzstan.
- -Kyrgyzstan is forced to release water from the
Toktogul reservoir as soon as fuel deliveries in
winter are interupted.

31State of Economic Development
- Different progress of economic reform.
- Privatization of coalmines in Kazakhstan prevent
freecoal deliveries to Kyrgyzstan. - Negative impact on the barter agreement.
- The barter agreement does not include any
mechanisms to solve these complications in the
context of infrastructure and economic problems. - The barter agreement does also not account for
the fact that the involved countries reform their
economic structure at different speed.
32Influence of Non Regime Variables
- Asymmetries
- Young age of the countries
- State of economic development
- Scientific understanding
33Scientific Understanding
- The Aral Sea problem as well as the Toktogul
dilemma are scientifically well understood. - Precipitation data and therefore the annual
inflow volume into the Toktogul reservoir can
roughly be estimated. - The outflow from the reservoir can quite exactly
be measured. - Measurements are likely to depend on whether the
data are obtained from national authorities or
from multi-national committees. The measurements
however do not really seem to affect the barter
agreement significantly because the huge outflows
in winter are definitely undoubted. - Scientific understanding and accurate
monitoring are, though being important from a
general point of view, not the key variables in
the Toktogul case and the barter agreement.

- Maintenance costs
- Time planning
36Decision Makers
- The Kyrgyz government decides when and how much
water is released from the Toktogul reservoir and
not as in the barter agreement the neutral Syr
Darya BVO. Actual releases are consequently
mainly triggered by Kyrgyz energy needs. - The barter agreement would work more efficiently
if a powerful integrated regional management was
introduced. - Liability rules could be introduced which punish
countries failing to fulfill their part of the
agreement and information exchange could be
improved. - So why is there no regional water management ?
37 Decision makers
- The countries are still very young and struggling
to find their own identity, which makes them
mistrustful towards any form of closer
integration. - The current water allocation bodies in the Aral
Sea basin are dominated by the Uzbeks, which
hampers a small country like Kyrgyzstan to be
more open to the idea of regional water
management of the Toktogul reservoir. - The Soviet thinking still seems to be dominant
among decision makers. Many water structures are
still strongly influenced by former Soviet
officials who keep to old hierarchies and do not
seem to be open for new ideas.
38Influence of Regime Variables
- Decision makers
- Involvement of international organizations
- Maintenance costs
- Time planning
39Involvement of International Organizations
- Though the influence of international
organizations on the concrete management and
operation of the Toktogul reservoir is very
limited the work of the United States Agency for
International Development (USAID) has been
essential - Without USAID the barter agreement would probably
not have been signed because they prepared and
funded the negotiations which lead to the barter
agreement in 1998. - Today USAID is involved in the modeling of an
optimal operation scheme for the Toktogul
reservoir. They provided both technical and
financial assistance. - Positive effect on the barter agreement.
40Influence of Regime Variables
- Decision makers
- Involvement of international organizations
- Maintenance costs
- Time planning
41Maintenance costs
- The maintenance of the Toktogul reservoir costs
about US 25 million per year, a sum Kyrgyzstan
can hardly afford. - Despite repeated requests, the downstream
countries refuse to share the maintenance costs. - That worsens the financial situation of
Kyrgyzstan, which is often forced to exceed the
agreed water releases (for domestic needs or
export to mainly China). - Fundamental question
- What do downstream countries actually pay for? Is
it the price for water which precipitates in the
upstream territory or is it the service provided
by Kyrgyzstan to store the water and release it
at several times. - A solution to this question would definitely
improve the payment behavior of the downstream
countries!
42Influence of Regime Variables
- Decision makers
- Involvement of international organizations
- Maintenance costs
- Time planning
43Time Planning
- The annual barter agreements have never been
reached before spring. - If they were signed before the beginning of the
year Kyrgyzstan would be able to estimate how
much energy deliveries it expects from the
downstream countries and therefore could release
less water from the Toktogul reservoir - Time planning is a key issue with respect to the
deficiencies of the barter agreement - Probably it can only be improved by reforming the
structures of decision making and management
44Conclusions (1of 3)
- Upstreamdownstream conflict emerged a decade ago
after the collapse of the USSR when a national
fresh- water management suddenly became an
international one. - After serious tensions the barter agreement was
signed in 1998 which acknowledges both the right
of the downstream countries to use water for
irrigation and the upstream countries to produce
energy. - The barter agreement has had a stabilizing effect
in the region. - Many failures of the barter agreement are caused
by the fact that it was not the mutual
recognition which lead to the signature of the
treaty but the pressure of counteracting
asymmetries.
45Conclusions (2 of 3 )
- The main problem is the management structure,
which is still in the hands of national
authorities rather than regional committees. - These structures are often based on tight command
economy principles which often do not coincide
with economic realities. - The 1998 barter agreement only focused on the
quantification of water releases and fuel
deliveries. The Toktogul dilemma is so complex
that also aspects like irrigation efficiency,
fragile infrastructure and maintenance costs
should be included. This however requires a
better cooperation and the willingness to
understand the point of view of the other side.
46Conclusions(3 of 3)
- The barter agreement will run out in 2003 and it
is yet unsure whether it will be extended. The
basis for a new barter agreement can only be a
closer cooperation towards an integrated and
regional water management. - NGOs should be involved in the negotiations and
a more flexible and automatic mechanism to
determine form and extent of compensation should
be introduced. - However up to now the involved countries think
improvement could be achieved by unilateral
plans. - A lot of convincing work still has to be done,
before the Aral Sea problem can seriously and
efficiently be tackled. - Tragically time is very limited.
