The country I don't understand how they do it is Bangladesh. A country the size of New York State with 164 million people. (50% of the US population). As I understand it, they generate 90% of the food they require.

The answers below are misleading by omission. While being on a river delta makes for fertile land, Bangladesh was nowhere near food independent a few decades ago. It was made so due to modern crop varieties and modern farming methods:

> During the last two decades and a half, important changes occurred in the realm of rice production and profitability. First, the cost of producing rice is several times higher than potato but the rate of profit is more than double for potato. Second, the yield of wheat, jute and potato has increased over time but the yield of rice has almost doubled from 2.16 t/ha in 1988 to 3.7 t/ha in 2000 and about 4.6 t/ha in 2014.

More than a factor of almost four increase in the yield of a staple crop that has been grown in that region for a thousand years is a technological miracle.

You raise a very good point about the increase in yield, but the reason Bangladesh has so many people in the first place is the fertile land. The lack of self-sufficiency in recent times may be due to the famines caused during the British Raj era.

From the wikipedia[0]:

>The country is notable for its soil fertility land, including the Ganges Delta, Sylhet Division and the Chittagong Hill Tracts. Agriculture is the largest sector of the economy, making up 18.6 percent of Bangladesh's GDP in November 2010 and employing about 45 percent of the workforce.[233] The agricultural sector impacts employment generation, poverty alleviation, human resources development and food security. More Bangladeshis earn their living from agriculture than from any other sector. The country is among the top producers of rice (fourth), potatoes (seventh), tropical fruits (sixth), jute (second), and farmed fish (fifth).

The reason so many people live there is precisely because they generate so much food. The ganges delta is perfect for farming rice (sans climate change)

Easy answer: Ganga-Bramhaputra delta (I do not know what they call it in Bangladesh).

To get a perspective: look at the map of egypt and map of their population density. Half the country is pretty much in Nile Delta and most of the rest is along Nile.

The subcontinent, and especially India and Bangladesh, have ridiculous amounts of arable land. India has more than any other country in the world.

But the dependence on monsoon balances it out, even makes it lopsided, except may be in some northern parts that rely on snow fed rivers.

A slight sea level rise will cripple farming in a large part of Bangladesh. I'm not optimistic about their future.

What can we do as computer scientists to best militate this risk and protect human life?

It has a lot to do with the Asian diet, this includes India and Pakistan too.

Most people in those countries do not consume large amount of meat, massively reducing their need for large amount of agricultural land.

Soil fertility is just part of the equation, does not explain Egypt, Pakistan and a multitude of other countries.

You clearly haven’t been to Pakistan anytime recently
