Prepared
the 7-volume Final Report, consisting of: Volume
1. Executive Summary. Volume
2. Classification of Project Proposals in Themes for improvement of
Agricultural Water Quality. Volume
3. The General Positions of the 5 Basin States On Water Quality. Problems and
their Solutions. Volume
4. Summaries of the National Reports of Uzbekistan, Kazakhstan, Kyrghyzstan,
Tadjikistan, Turkmenistan. Volume
5. Project Proposals of the National Working Groups. Volume
6. Analysis of Water and Salinity Data. Volume
7. Inventory of the Water Management, Situation in the Basin of the Amudarya
and Syrdarya rivers, the use of Land and Water Resources. It
was analysed dynamics of irrigation (from 5 mln.ha in 1950 to 8,0 mln.ha
up-to 1990) in Central Asia, followed by intensive withdrawal of water from
main rivers - Amudarya and Syrdarya (85 km3 and 48 km3 in average
accordingly). Large scale impact of such irrigation on natural resources have
caused worsening ecological and social situation in region: degradation of
the Aral Sea and spreading desertification on a vast territories, water
logging and land salinization, worsening quality of surface and ground
waters, drinking and irrigation water, declining crop yield and human
health. Considerable long term damage to environment had been happened by the
result of overuse and poor management of agrochemicals. Project
have recommended improving agricultural water quality on four level of
management - basin, oblast, district (rajion) and farm. Also it was analyzed
process of forming return and collector-drainage water. It was developed
inception plan of agricultural water improvement and its realization on 7
subprojects on pilot plots. Positive result which could be given on them will
be distributed for large
territories. Projects consist of: 1. Integral
management of water resources, including quality and quantity of water for
reaching optimal products on irrigated area. With minimal environmental
impact. Water saving and crop yield
increasing are planned to 10-15%. 2. Application
of biotechnology on farms will be increased efficiency of water using,
resulted by 10% of water economy and 30-40% of land productivity. 3.
Control of using agrochemicals, and
implementation of integrated methods of weed and insect control, modern
spraying technology will decrease pollution of environment by chemicals and
will increase land productivity up-to 30-40%. 4.
Optimal management of drainage systems,
decreasing their environmental impact will minimize mobilization salt from
geological stratas, will prevent land salinization and improve river water
quality. 5.
Utilization of collector-drainage water,
includes methods of their reuse, cleaning them on bioplateau and wetlands.
After that processes water could be used for salt tolerant fodder crop
growing and agroforestry. 6.
Regional transferring of salt mass,
assessment of ground water quality
calculation of water and salt balance, drawing real pattern of salt
migration. 7.
Water, salt and chemical substances balance
in the Aral Sea basin combined assessment of return and collector-drainage
water pollution from point and distributed sources for working out water
conservation measures. |
