Table 10.1. Projected water availability and demand. Based on a best guess of glacier area in 2050, this projection shows the number of people in
the Himalayan area who could be threatened by food insecurity due to changes in the Himalayan glaciers. Increased mean upstream rainfall partly
compensates for upstream water losses, although net irrigation demand may put more stress on the region's food security. The Yellow River basin,
where there is an increase in upstream water yield, is an exception. The Yellow River basin only marginally depends on glacial melt; thus there is
a notable 9.5 per cent increase in upstream water yield in the basin with an estimate of an increase of 3.0±0.6 million people that can be fed in the
Yellow River basin. Upstream refers to the area above 2,000 m altitude (Immerzeel et al. 2010). *Upper Indus.
