Today, the
Government of Uzbekistan and the World Bank signed a
US$74.55 million Drainage, Irrigation and Wetlands
Improvement Project. The Project is aimed at increasing
productivity of irrigated agriculture, employment and
incomes in Karakalpakstan, improving water quality of
the Amu Darya river by safe disposal of drainage
effluent, and enhancing the quality of wetlands in the
Amu Darya delta. It will also develop institutions for
improving water management, operation and maintenance of
irrigation | and drainage systems, and for promoting sustainable
irrigated agriculture through participatory irrigation
management.
Intensive
development of new irrigated areas in 1960-80-es was
accompanied by land salinization, water logging, land
degradation and increases in the discharge of highly
mineralized drainage water into the Amu Darya river through a
system of collector drains. These led to increased
mineralization and pollution of the river, as well as negative
impacts on the health of the population and on agricultural
production.
"By improving
drainage, the Project would be the first meaningful
intervention in the Aral Sea Basin to break a vicious cycle of
high water applications, waterlogging and secondary soil
salinization, hence requiring again high water applications
for leaching the next season. The Project would make a start
in addressing this problem by substantially improving drainage
conditions and significantly improving water use efficiency in
irrigation sector", said Masood Ahmad, head of the World Bank
team designing the Project
Implementation of the Project will solve a number
of vital issues for Uzbekistan: -
Drainage water waste from the Beruni collector will no longer
be discharged into the Amu Darya river with direct health
benefits for the population in the northern regions of
Karakalpakstan where the Amu Darya is still the main source of
drinking water; - the quality of
100, 000 ha of land in three southern districts will improve
significantly, crop yields will increase while the amount of
irrigation water use per ha will decline; - drainage water will be collected and discharged
through a system making use of the northward downward sloping
terrain, allowing the substitution of electric pumps with
natural gravity, thereby generating significant electric power
and cost savings; - the Badai-Tugai
nature reserve will cease receiving salinated water for
irrigation purposes with significant benefits for the
preservation of the vegetation in this unique
environment.
The Ministry of Agriculture and Water
Resources takes the responsibility for timely implementation
of the project.
