World Corn Production… Go Canada?
WOW! This has to be the best visualization tool for the world’s agricultural data which I’ve found to date.
Gapminder has done an incredible job here exposing some of the UN’s data and made it very easy to ‘fool around’ with.
Here is one of the animated graphs I’ve made:
Visualization from Gapminder World, powered by Trendalyzer from www.gapminder.org.
For each country it shows hectares of corn harvested, the yield (kg per hectare) and the total number of tons produced. Hit the “Play” button to see it change over time! Bubbles moving up it means the country harvested more hectares of corn, bubbles moving right means the country has improved overall yield.
There are three things that instantly struck me:
- Canada is not the agricultural powerhouse which I had perceived it to be. There are MANY countries which plant far more hectares of corn than we do! (The Philippines cover twice as much land as we do with corn crops — pretty incredible considering their size and how many other crops they grow like rice and oil palm [see image below: orange islands beside British Columbia for contrast])
- It really makes me wonder if GMO corn improves a nation’s overall yield. It is my understanding that France, Germany, Greece, Hungary, Austria and several other countries have banned the cultivation of GMO corn. However, their annual yield is right up there with Canada’s. In fact, most of said countries SURPASS Canada’s annual yield.
- Annual yield jumps all over the place. While it does seem to trend slowly towards increased yield, the same happens for other nations who have more family farms and less access to technology.
Head on over to gapminder.org and make some charts of your own. It’s too easy… making a similar chart to the one above about strawberry production with a logarithmic scale.
