Analytical survey� assessment of the environment� assessment of present water conditions� identification of destabilizing factors� assessment of existing material,
financial and other resources� evaluation of available water
development� assessment of institutional and legal
aspects� identification of the key challenges of
future development
Present environmentallosses:
Toxicological risk – 3.3 mln USD:Fish productivity – 1.05 mln USD;Human health – 10.0 mln USD;Agricultural – 12.5 mln USD.
Future socio-economic development isdetermined by a few key lines that arecharacterized by the following indicators:
� demographic indicators (growth, morbidity,migration, employment);
� gross national income and its growth rates;� change in industrial production volume;(?)� change of energy demands and
requirement;� change in volume of service sector output;� capital investments, including local, loans,
foreign;(?)� capacities to meet national food demand.

• Population growth trend is at the same level (forboth rural and urban population)
• Economic growth at current level (2003-2005)• Economic structure without changes• Industry and services without changes• Capital investment amount at the same level• Extension of private farming, gradual transition to
free market economy.• As to irrigated agriculture, no changes in:
� institutional aspects of water management and actual waterdelivery regime;
� costs for rehabilitation and maintenance of inter- and on-farmirrigation and drainage systems.
� machinery maintenance costs.
Business as usual scenario
Stable population
• Moderate, sustainable economicgrowth.
• Gradual sustainable industrialdevelopment, full use of potential.
• Increased role of private small andmedium scale business.
• In irrigated agriculture:� speeded up privatization of farms, with
appropriate raise in farmers’ income;� institutional changes, implementation of IWRM;
