Why does Bangladesh flood?

• With a population of 120 million people packed
  into a land mass no bigger then a small US State,
  Bangladesh has the distinction of being one of
  the most densely populated countries of the
  world.

5

• 90 of the population live in the rural sector
  where the people endeavour to survive through
  subsistence farming and fishing.

6

• With over 2000 people per square kilometre, land
  and marine resources are over exploited and daily
  nutritional rates are extremely low.

7

• This, combined with lack of industry, low
  literacy rates, poor health care and almost
  yearly flooding, make Bangladesh one of the most
  impoverished and under nourished nations of the
  world.

8

• It is estimated that at the current birth rate,
  the population of Bangladesh will double in the
  next 30 years, bringing the population to a
  staggering 240 million by the year 2026.

9

• 90 of the land area of Bangladesh is situated on
  a vast alluvial delta where the flat countryside
  rarely rises ten metres above sea level. With the
  yearly monsoon rains comes vast flooding as the
  river system overflows their banks

10

• This is both a blessing and a curse. While the
  floods destroy crops and endanger the lives of
  people and animals, the annual deluge also brings
  fertility to the soil, allowing for rich crops
  through the rest of the year without the use of
  expensive fertilizer.
