Annihilati­on

-

O Just nine plant species of the 6 000 that have been cultivated for food by humans account for 66% of crop production;

O 26% of the 7 745 local breeds of livestock are classified as at risk of extinction because of the focus on bigger and more productive breeds;

O 33% of fish stocks are overfished and 60% are fished to the maximum sustainabl­e amount;

O Just 7% of fish stocks are underfishe­d; O 17% of invertebra­te pollinator species, such as bees, are threatened with extinction; and O 70% of inland wetlands have been lost since 1900. — Sipho

Kings the species that have evolved to thrive in these environmen­ts.

In other research published last month in the journal Biological Conservati­on — Worldwide Decline of Entomofaun­a: A Review of its Drivers — Francisco Sánchez-bayo and Kris Wyckhuys warned that these three things are driving insect species across the world to extinction. “It is evident that we are witnessing the largest extinction on Earth since the late Permian and Cretaceous period [65-million years ago].”

Addressing the effect of the biodiversi­ty collapse, the FAO researcher­s say: “The reliance on a small number of species means we are more susceptibl­e to disease outbreaks and climate change. It renders food production less resilient.” As an example of how this plays out, the organisati­on references the Irish potato famine of the 1840s. Under a colonial regime, the country’s farmers grew that single crop and relied on its income for food. Then a fungus, lasting several years, wiped out the crop. A million people died.

With a changing climate and more storms, droughts and other extreme weather events happening as a result, the more species the better. That concentrat­ion of 66% of food production in nine plant species increases the chances of a new fungus wiping out food security. South Africa, for example, grows just enough white maize to feed people in a year when there are good rains. When it doesn’t rain, the country has to import food. By focusing on that single crop, the country is vulnerable to something that eats maize or causes the crop to fail.

But the FAO’S report does come with a small dose of hope. More and more countries are taking increasing notice of local biodiversi­ty failure, and how this is affecting food production. In the past 20 years, for example, 20% of the area of the world covered in vegetation has become less productive.

To prevent this, the organisati­on says that most countries now have a legal framework in place to ensure sustainabl­e use of land. But this is where it stops. Besides pointing out that not enough attention is being focused on the collapse of biodiversi­ty, the FAO warns that government­s, companies and people have “a large knowledge gap” and lack awareness about this destructio­n.

And this threatens the ability to feed eight billion people.
