The Central Asia Regional Water Information Base Project (CAREWIB) aims at the improvement of information provision in water and environmental sectors in Central Asian countries in order to promote transparency openness and foster public support for rational natural resources use.
The project implements by SIC ICWC in Tashkent, UNECE, Zoi Environment Network with active participation of EC IFAS and ICSD with financial support of Swiss Agency for Development and Cooperation (SDC).
The Information System on water and land resources in the Aral Sea basin is designed first to support decision-making process in water sector in Central Asia. The Information System is a practical tool for comprehensive assessment of water situation (available water resources for use and allocation of them among river reaches, provinces and water management systems; operation modes of reservoirs and hydropower stations; water losses, deficits, imbalance, environmental flows, water quality indices and so on), with elements of analysis and suggestion, and a means for dissemination of required data checked and adjusted by the states. It will enable regional and national organizations to transfer to a common “informational language” that will help raise the validity of data being used, and therefore raise the effectiveness of water resources management.
Data validity supposes checking and adjusting them, including by using models, and consistency among the states, when data discrepancy and inaccuracy are reduced to minimum, when data evaluation and prediction is transferred to common methodical basis (calculation of losses and so on).
The Information System provides different levels of access to presented information: every user has his key and can view and correct his information, and also view data characterizing the situation with neighbors, including consequences of his actions.
Analytical reviews give possibility to assess water management situation of the Amudarya and Syrdarya Rivers and their sections and one can see the followings:
- scheduled (predicted) and actual parameters of tributaries, releases, reservoir storage, water withdrawals;
- deviation of the scheduled (predicted) water availability for water intake from the actual one.
Database and a set of developed models enables each of the participants (water management, planning and other authorities of Central Asian countries, as well BWOs) to predict their development options for the future and the release mode and water allocation in the current situation, for assessment of impact of their activity on other countries and some planning zones. At the same time an efficiency of water use by each participant of joint water management can be assessed at any time, and the unproductive water withdrawal can be determined.
Regular information on the natural water resources and their prediction, the comparison of the on-line predicted and actual data on the water resources use and channel balances of major rivers of the region makes it possible to improve water resources management and builds trust, unity and responsibility between countries and economic sectors.
Existing data for the period 1991 - present is being replenished in each ten-day period.
