Intense debate persists about the climatic mechanisms governing hydrologic changes in tropical and subtropical southeast Africa since the Last Glacial Maximum, about 20,000 years ago. In particular, the relative importance of atmospheric and oceanic processes is not firmly established.

An estimated 800 million urban dwellers lack access to safe and adequate drinking water. Most of those people live in unplanned, low-income areas and slums. The vital role of groundwater for this group remains largely unexplored despite that some 50 per cent of all urban water use worldwide is attributed to well, spring and borehole sources.

Adult deaths are a crucial priority for global health. Causes of adult death are important components of Millennium Development Goals 5 and 6. However, adult mortality has received little policy attention, resources, or monitoring efforts. This study aimed to estimate worldwide mortality in men and women aged 15
