Assessment of the vulnerability of freshwater resources to climate change: impacts on the sharing of water resources in the Western Asian region United Nations Environment Programme (UNEP). In 2012, Asian countries experienced varying degrees of natural and anthropogenic water risk that affect the sustainability of their limited water resources and the maintenance of ecosystem balance. The fragile dry environment and its resilience to external natural and anthropogenic activities, including the expected effects of climate change, pose a major challenge for decision-makers who must achieve an adequate, safe and reliable supply of water and food in the future in order to improve human well-being in their societies and meet the demands of future generations. This document provides decision-makers with a useful tool to identify potential risks to the region`s freshwater resources due to the effects of climate change. The overall objective of this study is to conduct a national and regional assessment of the vulnerability of freshwater resources in order to better understand the current state of water under current conditions and to identify the most dominant factors influencing vulnerability. A first look at the issue of water contracts in the region therefore seems to indicate that there is little political will in China to conclude equitable water-sharing agreements. This may be true or perhaps true, but the issue is undoubtedly complex; Neighbouring countries themselves are often in conflict over shared water resources and climate change, and transboundary aquifers add a whole new dimension to the problem. Our waters: beyond borders. First assessment of transboundary rivers, lakes and groundwaters [ – 15.25 MB] United Nations Economic Commission for Europe (UNECE). 2007 This publication describes the hydrological regime of 140 transboundary rivers and 30 transboundary lakes in the European and Asian parts of the region, as well as 70 transboundary aquifers in South-Eastern Europe, the Caucasus and Central Asia, as well as the pressure factors in their basins, status and transboundary impacts, their trends, future developments and planned management measures. .
