• How can a science-
based Integrated Water
Resources Management
in Mongolia as a pilot
region for Central Asia
be developed ?
• How can regional water
planning and manage-
ment react on Global
Change in a coherent
way?
• What are effective
regional adaptation
strategies and how can
these be implemented?
