Visualizing the Material Impact of Global Urbanization

Cities only cover 2% of the world’s land surface, but activities within their boundaries consume over 75% of the planet’s material resources.

With the expansion of urban areas, the world’s material consumption is expected to grow from 41.1 billion tonnes in 2010 to about 89 billion tonnes by 2050.

In today’s graphic, we use data from the UN International Resource Panel to visualize the material impact of global urbanization.

How Material Consumption is Calculated

Today, more than 4.3 billion people or 55% of the world’s population live in urban settings, and the number is expected to rise to 80% by 2050.

Every year, the world produces an immense amount of materials in order to supply the continuous construction of human-built environments.

To calculate how much we use to build our cities, the UN uses the Domestic Material Consumption (DMC), a measure of all raw materials extracted from the domestic territory per year, plus all physical imports, minus all physical exports.

Generally, the material consumption is highly uneven across the different world regions. In terms of material footprint, the world’s wealthiest countries consume 10 times as much as the poorest and twice the global average.

Based on the total urban DMC, Eastern Asia leads the world (Read more...)

The History of the Abitibi Gold Belt

The Abitibi: Canada’s Golden Powerhouse

At the heart of Canada lies a greenstone belt that has provided the nation with more than 90% of its gold production. With more than 100 years of gold discovery in the Abitibi region located between Québec and Ontario, this area was the kiln that helped forge the Canadian mining industry.

Ever since the discovery of gold at Lac Fortune in 1906, the Abitibi has grown to become one of the world’s most prolific gold mining regions, and has produced over 190 million ounces of gold.

This graphic sponsored by Clarity Gold maps the history of gold discovery in the Abitibi and showcases the region’s overburden thickness. With a history of prolific discovery and production, there’s still plenty to explore under the Abitibi’s areas of thick overburden.

A Timeline of Gold Discovery in the Abitibi

Canada, known more for beaver pelts and timber, did not reveal its riches immediately. There were only a handful of gold discoveries in its early history. Gold was first discovered in 1823, on the shores of Rivière Chaudière in Québec, further east of the region known as the Abitibi today.

But as settlers spread west, gold surfaced in British Columbia and the Yukon in the late 1800s, kicking off the Cariboo and Klondike gold rushes. It wasn’t until the 1900s that gold was found in the Abitibi greenstone belt, marking the beginning of the modern era for the Canadian (Read more...)
