Central Asia
In the Lower Amu Darya, water-supply
to populations has used groundwater
for a long time.
Developing new lands for irrigated agri-
culture, flow diversion from the river
and discharge of high mineralization
drainage water into the river resulted in
decrease in the water flow in the Lower
Amu Darya, increase in mineralization
of surface water and degradation of
groundwater.
By the end of the eighties, groundwater
mineralization increased higher than
admissible for drinking water in the
most part of the explored aquifers.
Water-pipes for drinking water-supply
from the Tuyamuyun reservoir did not
solve the problem as the quality of sur-
face water does not meet the quality
requirements in the low-flow periods.
In the current situation, artificial
groundwater recharge seems to be the
sole solution. This method is expen-
sive. An analysis of the groundwater
status was realized.
The studied 64 water tables are located
in Horezm and Karakalpakstan region.
The artificial recharge used for 16 water
tables enabled to rehabilitate ground-
water quality.
The reconstruction of water supply
points was realized in 2005 - 2007 in
accordance with the
“Uzbekistan -
Pure water, sanitation and health”
program for the Biruni, Turtkuli, Chim-
bay and Kegeyli cities.

Ground water resources management on the Lower Amu Darya River
The Amu Darya River
Eastern Europe - Caucasus - Central Asia
Countries of Eastern
Europe, Caucasus
and Central Asia are
highly dependent on
transboundary water
resources.
To develop an effec-
tive Integrated Water
Resources Management
(IWRM) policy, it is necessary to have a
comprehensive assessment of water
resources and uses, which is based on
consistent and coherent information.
This project funded by
the French
Global Environment Facility and
developed under the "Convention
on the Protection and Use of Trans-
boundary Watercourses and Inter-
national Lakes",
aims to improve
water data administration in order to
facilitate the production of the informa-
tion needed.
IWAC (International Water Assess-
ment Center), the main recipient of
the funding, entrusted the Interna-
tional Office for Water with the
technical coordination of the pro-
ject activities.
Activities were launched in early 2011
in two pilot transboundary basins:
l
The Dniester River Basin
in
Ukraine and Moldova;
l
The Aral Sea Basin
(Amudarya
and Syrdarya river basins) which
concerns Kyrgyzstan, Kazakhstan,
Uzbekistan, Tajikistan, Turkme-
nistan and Afghanistan.
The assessment of water data adminis-
tration carried out in each country
includes:
n
A legislative and institutional
analysis (database of the stakehol-
ders);
n
Organization of national workshops
gathering the key stakeholders
involved in data production and
management;
n
Support to the presentation of data
sources by the producers (meta-
data catalogue);
n
Production of data flow charts (who
exchanges what with whom?);
n
An initial needs analysis related to
data management.
The developed actions provided the
following results:
In the Dniester River Basin
v
Procedures and tools for the calcu-
lation of indices of surface water
quality, with online publication of
dynamic maps updated by the
partners;
v
The "Web Processing Services"
allowing the production of useful
geographic data;
In the Aral Sea Basin
A prototype of hydrological bulletin
on the Syrdarya, within an action
initiated by the
UNRCCA
and
EC-IFAS;
Conceptual analysis of the National
Water Information System in Taji-
kistan;
An online interactive diagram
of the Syrdarya hydrology in
Kazakhstan.
The final phase of the project (2nd
quarter of 2013) will allow the transfer
of the project's feedback to the national
and regional beneficiaries, and the pro-
duction of guides highlighting the les-
sons learned for transfer to other trans-
boundary basins of the region.
The main results are available on the
website (in English and Russian) and
were officially presented at the
6
th
Meeting of the Parties of the
Water Convention
in Rome on 28
November 2012 on UNECE initiative.
