ABOUT PARTICIPATION OF PRESIDENT OF KAZAKHSTAN N.A. NAZARBAYEV IN OPENING CEREMONY OF PROJECT INITIATION «REGULATION OF BOTH SYRDARYA RIVER CHANNEL AND ARAL SEA NORTH PART»

Project “Regulation of both Syrdarya River channel and Aral Sea north part” have been developed and is implementing within frameworks of Program of concrete actions on environmental situation improvement in the Aral Sea basin and Priaralie approved by Head of the States of Central Asia in Nukus.

From whole range of appropriate measures foreseen under project emergent priorities were underlined, for implementation of which investments in amount 85.8 mln. USD are required, including over structures:
- dam and spillway of North Aral Sea - 23,2 mln USD
- Aklak Waterworks - 17,6
- Aytek Waterworks - 15,25
- repair of Kyzylorda and Kazakinsk Waterworks - 4,4
- dikes - 3,7
- Shardarya dam rehabilitation - 14,5

In connection with the starting this project implementation in the Aral Sea basin President of Kazakhstan N.A. Nazarbayev visited Kyzylorda oblast on April 13, 2000.

He studied course of construction, material and technical resources provision, labor conditions of engineers and workers.

Chairman of Committee for Water Resources at Ministry of Agriculture of Kazakhstan A.D. Ryabtsev reported President about project goals and tasks.

In result of project implementation following outputs will be obtained:

1. Dam on North Aral Sea
- under water level 42 m dried seabed will be covered by water surface area 870 km2, water volume in North Aral Sea will increase by 11,5 km3.
- seawater salinity less than 17 g/l
- favorable conditions will be created for breeding of local fish species
- industrial fish catch will increase by 11,7 th tons
- social-economic situation of Priaralie population will improve and number of job places will increase

2. Aklak Waterworks
- flow capacity of the structure will be increased from 60 to 400 m3/s
- water inflow in delta and North Aral Sea will increase
- water availability of lake systems and arable haylands will increase
- Syrdarya River channel erosion process will be stopped for some time
- state of wetlands and biovariety will improve

3. Aytek Waterworks
- Syrdarya River flow capacity will increase from 300 to 750 m3/s (including Karauzek Waterworks – up to 1000 m3/s), that will allow increased discharge in winter
- water availability of 15,3 th ha irrigated lands will increase
- Syrdarya riverbed flushing will be provided and Kyzylorda city water logging will reduce
- salt and dust transfer will reduce, and environmental situation in North Sea coastal zone will improve.

On the meeting of President with experts from agriculture and water management of Kyzylorda oblast veterans of labor A.D. Ryabtsev and N.K. Kypshakbayev presented their opinions and proposals. Issues of water infrastructure rehabilitation, increase of state donations for these purposes were raised, and especially necessity of qualified young specialists training for water management was noted.

President N.A. Nazarbayev asked to pay attention to quality of waterworks construction and pre-schedule launch of these objects that is very important under such environmental state of region. President concerned about issue – when North Sea level will reach Aralsk town, as before.

ICWC TRAINIG CENTER WORKSHOP “PROBLEMS OF DRAINAGE AND IRRIGATED AGRICULTURE IN ARID ZONES”

Conduction of workshop on this topic is caused by increased necessity disseminating available practical and research knowledge gathered in five states of Central Asia in conditions complicated by recent low water years and necessity of immediate introduction of water saving technologies and elaboration of measures on drainage systems rehabilitation.

Workshop agenda and thematic of reports were oriented on creation of conditions for exchanging experience of advanced approaches to solution of drainage systems operation as well as irrigated agriculture between high and middle level experts and scientists from Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.

Workshop participants – workers of reclamation services at water and agricultural organizations of Central Asia – from 21 to 25 of April 2003 have been studying reports on problems integrated within 5 modules:

  • General issues of irrigated agriculture reclamation;
  • Reclamation regimes and land productivity increase;
  • Present problems of drainage systems operation;
  • Water consumption, water saving technologies, and water productivity increase;
  • Software for irrigation management.

In workshop opening following officials took part and greeted participants: Deputy Head of Water Department Kh.Kh. Ishanov, USAID representative A.G. Kalashnikov, Regional Director of START/AED program in Uzbekistan D. Kompi, SIC ICWC Director V.A. Dukhovny, honored ICWC member, Director of ICWC Kazakh Division, Prof. N.K. Kypshakbayev, Head of Irrigated Land Reclamation Improvement and Monitoring Unit at MAWR of Uzbekistan M.M. Mirkhojiyev.

Training participants noted high level of prepared materials and reports, wide scope of topics and variety of water sector fields proposed to participants, including issues of integrated water resources management introduction on base of:

  • water supply and water diversion of irrigation and drainage;
  • interaction of different types of drainage (surface, subsurface, horizontal, vertical, and combined);
  • integration of use and management by different types of water (surface, ground, return).

From these position necessity of managing system of large tracts, collectors as well as system of wetlands and lakes by forces of basin water organizations (BWO) and national (or territorial) reclamation bodies, while operation of regulating drainage network is responsibility of local water organizations including WUAs.

It was noted that currently under present treatment to drainage systems constructed several decades ago sharp problem of these systems failure will emerge in the nearest future. Because of lack of financial means cleaning works are not fulfilled on drainage systems and irrigation structures, even experimental-production plots are abandoned. Practically all fleet of reclamation machines and mechanisms including draining cleaners and pumps failed. In late 80-ties- early 90-ties building industry capacities on pipes production reached annually up to 11 th. t of polyethylene and polyvinylchloride drainage pipes, 2000 km of drainage ceramic pipes, 6 mln m3 of sand-gravel filter materials, quantity of drainlayers exceeded 100 units, and fleet of drainlayers allowed cleaning of 2500 km drains annually. Every year about 600 wells of vertical drainage were constructed. Presently total capacity of reclamation machines fleet declined 10 times, drainage pipes production – 100 times, drain cleaning – 15 times. If earlier frequency of inter-farm collectors cleaning was once per 3 year, and on-farm – once a year, so now it reduced 2.5-3.0 times. All these technical and operational shortfalls became particularly dangerous for perspective land fertility. Everybody knows that without sufficient state support it is impossible to maintain and repair drainage systems. Students noted necessity of implementing state investment programs on drainage measures provision, as already for past decade, on different estimates, areas of highly and medium saline lands in region increased by 600-800 th. ha. Dangerous salinity centers remained there, where before sustainable desalinization was achieved on the background of drainage systems (Makhtaaral zone in Kazakhstan, west part of Hunger Steppe lands in Uzbekistan, etc.). In the same time there are many examples, when attraction of local administration attention (for example, in Bukhara oblast in Uzbekistan) allows maintenance of drainage network in proper state. Thus public participation in management and maintenance of collector-drainage systems becomes very critical from the point of view of necessity to strengthen attention of all community to management issues not only in water, but salts and simultaneously for elaboration and implementation of measures on involving stakeholders in drainage measures.

Students pointed in their reports that often aggravation of operation of drains and collectors is caused by their wrong use, ignorance of disturbances, and sometimes deliberate release of irrigation water in collectors. Therefore public participation will provide organization of network maintenance control contributing in technical drainage state improvement by not necessarily drainage means, but also indirectly work on drainage flushing, cleaning of observation wells and repair of mouth structures, protection of vertical drainage wells from destroy and robbing.

Workshop participants think that this training promoted better understanding of available problems, allowed students to systematize own knowledge as well as broaden their view. Also usefulness of information presented by reporters was noted for development of specific measures on improving drainage systems operation.

Data and information obtained during discussions, which belong to routine activity of water experts, deepened awareness of national features of Water Users Association creation process, development of water tariffs, hydrometrology, and management framework. It was said that given training gave opportunity to better understand financial-economic situation in water sector, technical provision and general situation in reclamation field as well as features of zoning irrigation methods, water use efficiency assessment in irrigated agriculture, and elaborate appropriate decisions.

Students emphasized necessity to intensify work on forestation in water user awareness concepts of careful treatment to water use and wider and more gradual introduction of advanced water saving methods in practice of irrigated agriculture.

Workshop participants expressed opinion that presently sufficiently effective stimulating levers on supporting farmers’ activity on maintenance and reconstruction of drainage and irrigation systems and structures still have not been created.
