The UN Watercourses ...

The UN Watercourses Convention User's Guide from 2009 (http://www.gwp.org/Global/Our%20Approach/Strategic%20Allies/User's%20Guide%20to%20the%20UN%20Watercourses%20Convention%20(2012).pdf) shows the worldwide water scarcity on page 26, with Pakistan approaching/experiencing physical water scarcity, much like the neighboring areas. Will people continue to live in water scarce areas or will they be forced to migrate simply to get their basic human needs? I have yet to hear a discussion about the possibilities of a less steep increase in the number of humans living in water scarce areas, or of migration to areas with better resources. Since ultimately the governments are responsible for resource management and human rights, agreements with areas not suffering as much from water scarcity seem appropriate.
