600 million people in the Ganges/Brahmaputra Basin live at elevations below 1,000 m.2 Most of those living below 1,000-m elevation are in India (79 percent) and Bangladesh (18 percent; Table 3.3). Even in Nepal, where 29 million people live in this basin, almost two-thirds live below 1,000-m elevation. Even in mountainous Bhutan, more than one-quarter of its population in the Ganges/Brahmaputra basin lives at an elevation below 1000 m.

On a global scale, the countries of this region encompass some of the world’s poorest and least developed areas, alongside areas that are also experiencing rapid economic growth. The region is characterized by relatively low shares of the population living in cities.


2 In Bangladesh, furthermore, nearly 60 percent of the population lives within 10 m of sea level and contiguous to the seacoast.

3 One thing that makes Asia stand out, particularly the subregions dependent on the water resources of the Indus and Ganges/ Brahmaputra deltas, is the number of extremely large cities, or the phenomenon of urban “giganticism” (Preston, 1979).
