\textbf{Abstract}
\begin{abstract}
\normalsize{
Balancing water demand for the whole basin efficiency is priority task in the world. This is especially true in the arid regions with the limited resources and transboundary conflicts over water resources. The Aral Sea basin one of the biggest inland watersheds in the world and an example of serious environmental stress due to misuse of water resources and water conflicts. In this study we investigated impacts of climate change in the Amu Darya through several scenarios and hydrological modelling. Then demonstrated marginal waters potential and quantity calculations to address water distribution in downstream under climate change impacts. 



Several research fields to investigate marginal lands and soils potential in creating additional source of nutrition for agro pastures from salt"=tolerated plants that can survive extreme conditions has been established. Our findings show how plants interact with water and soil environments to adapt and cope with high concentrations of nutrients and toxicants, which occur naturally or as pollutants on such soils. Study on remediation strategies and adaptation measures to address future shortage of water in extreme conditions can be an important factor for the agriculture and economic growth ensuring food security in the region. However, there is little or no information on utilisation of low quality waters and salinized lands for alternative agriculture use in Central Asia, even though developing such techniques would be clearly advantageous, as such lands are underused, and these methodologies would not be in any competition with already existing farming practices. Utilisation of both marginal waters and lands under a climate change water scarcity scenario can be a potential way of addressing forage availability without requiring fresh waters from river and improving environment. Therefore, the current debates of climate change impacts on socio"=ecological systems are oriented towards developing strategies for adaption to the expected adverse impacts and increased water stress.
