In the region of central Asia and Caucasus (CAC), collection, assessment and sharing of information on water and land resources, previously under
central command of the Soviet Union, have been fragmented during the past decades. In fact, the
regional program has supplemented an important role in supporting and facilitating data assessment
and knowledge sharing. The presentation will highlight some results from the recent assessments of
water resources and climate change impact, ground water storage capacity as an alternative water
source, human impact on water and soil quality, marginal water use, and ecosystem-based intervention
for improvement of water and land productivity specifically around the Aral Sea.
