Visualizing the History of
Decreasing World Hunger and Improving Food Provision

Over the course of the last 3 centuries food availability improved - this is shown here for 3 countries

This chart shows averages - to understand how bad the food supply was in the past we look at the huge inequality of food consumption on the next slide.

The social historian Robert Fogel - who compiled the data visualised below - notes: 'Individuals in the bottom 20 percent of the caloric distributions of France and England near the end of the eighteenth century lacked the energy for sustained work and were effectively excluded from the labor force.'

The following chart shows food prices started to fall with the onset of modernity - thereby making food available for larger and larger parts of society.

One of the many beneficial consequences of decreasing world poverty...

Check_OurWorldinData

...is that food provision is now improving around the world.

We will look at this on a world map...

Just a quick heads up: All of the visualisations in this presentation are from my website 'Our World in Data' and by clicking on any of them you'll be referred to the interactive visualisation.

As food provision is improving, the share - and number - of undernourished
people
in the world are falling.

This is the share of undernourished people in 1990-92 (top) and 2010-12 (below).

A major change for the world is that famines have become very rare.

One of the many reasons for declining food crises is increasing food trade - shocks to local food markets (due to weather or plant diseases) are thereby absorbed.

As these shocks to food markets will be reflected in price changes (volatility) one can study the increasing resilience by looking at the decreasing volatility over time.

Improving food provision and food security are major drivers for improving health around the world.

And this is how health has improved over the last 200 years.

As a consequence of improving health and food provision the world population rose from less than 1 billion in 1800 to 7 billion today.

The fact that the world population skyrocketed and food provision did
improve at the same time
make this accomplishment even more impressive.

This could only be accomplished by modernizing agriculture around the world.


And this is what we will look at now...

With the help of fertilizer and improved seeds we increased yields (crops per area) massively.

This meant that we produced much more food without increasing the agricultural land - whereby we reduced the impact on the environment.

Check_OurWorldinData

These productivity increases are reducing the agriculutural land per person and will continue to save our environment.

Check_OurWorldinData

This means that the agricultural land use did not increase much and is projected to shrink over the next decades. Even though the world population is still increasing!

The documented productivity increases also made it possible that fewer and fewer people are working in agriculture.

In Europe...

...and around the world modernisation leads to a shift away from the agricultural sector.

Check_OurWorldinData

And by freeing the labour force for manufacturing and service jobs, the agricultural modernisations reinforces the reduction of world poverty in a positive feedback loop.
