A recent study based on satellite data estimates that there are 3 trillion trees on Earth - that’s over 400 trees per person. That also means that there are more trees on Earth than stars in the Milky Way.

Forests are key to climate, water, health and livelihoods, and to mark the International Day of Forests, we’ve taken a look at the upcoming World Development Indicators 2016, and highlighted some trends in how forest cover has changed in the last 25 years.

We’ve lost 1.3 million square kilometers of forests since 1990 - an area larger than South Africa

Forests cover a third of the world’s land. At the beginning of the 20th century, the Earth’s forest area was about 50 million square kilometers.  This has since shrunk to less than 40 million square kilometers.  Most of this decline was caused by the growing demand for forest and paper products, as well as for agricultural land use.

In the last 25 years, the world’s forests shrank by 1.3 million square kilometers. Which means that since 1990 the world’s lost more forest area than the size of South Africa. Another way of thinking about it: since 1990, we’ve lost the equivalent of 1,000 football fields of forests every hour.  Or about 800 soccer pitches an hour if that’s your thing.

Latin America lost 10% of its forest area in the last 25 years

When we break things down by region, Latin America & the Caribbean has the world’s second largest share of forests (after Europe & Central Asia), with about one quarter of the world’s total. Since 1990, the region has lost some 970 thousand square kilometers – 10 percent of its forest area.

 

The world’s forests aren’t evenly distributed


If you really want to look at where the world’s forests are, I’d highly recommend visiting the Global Forest Watch interactive maps. Based on country-level statistics though, it’s unsurprising, yet still striking, that the world’s largest countries also have have the largest forest areas - seven of the ten countries above are among the top-10 largest countries by land area.

 

By 2012, more than 14% of the world’s land had been nationally protected


Protected areas - both terrestrial and marine are critical for the protection of key biodiversity efforts that would otherwise face decimation due to the pressures from the demand for food, materials, and energy.

Many countries have designated a share of their land and marine areas as protected areas to preserve valuable habitat and the plant and animal species that live there. By 2012, more than 14% of the world’s land area and about 10% of its territorial waters had been protected.  As of 2012, Latin America and the Caribbean and Sub-Saharan Africa had the largest areas of protected land.
