What is a hectare (ha)?

•Unit of measurement•Commonly used for measuring land•100m x 100m•2.47 acres•Approximately one official soccer field

Earth

51 billion hectares

PARTIAL LAND

PRODUCTIVE

Let’s Do the Math…• 51 billion hectares

LAND:

• 18% of that is productive land

• How many hectares of productive land?

WATER:

• 5% of that is productive water

• How many hectares of productive water?

Not a whole lot of room!

There are over 7 BILLION PEOPLE

who live on the Earth

That means there’s only 1.7 hectares

available for each of us!!

Not all footprints are the same…Every lifestyle has a different footprint,

and on average, so does every country…

Available

1.7 ha

Canada

8.8 ha

India

0.5 ha

United States 10 ha

In Canada, our footprint is

That means we are using more land than is available to sustain our lifestyles

8.8 hectaresper person
