| With less than 3 percent of its land farmable and little industry, Chad is a desperately poor country. |
|
| Most of the farmable land, in the middle of the country, is used as grazing pastures for livestock. |
|
| China has about 20 percent of the world's population, but only 7 percent of the world's farmable land. |
|
| About a third of the planet's farmable land is infertile due to over-use. |
