Ten countries worldwide, including five African nations, are at “extreme risk” because of limited access to clean, fresh water, according to a new global water security index. And the effects of climate change and population growth will exacerbate the stress on these water supplies, potentially threatening stability in many regions, according to the analysis by Maplecroft , a UK-based consulting group. Among the nations most at risk are Somalia, Mauritania, Sudan, Niger, and Iraq. Other nations at extreme risk — including Pakistan, Egypt, and
