Visualizing the Rhine River’s Shrinking Water Levels
Visualizing the Rhine River Water Levels Over the Last 20 Years
Water levels on the Rhine river in Germany continue to sink amid severe drought, forcing companies to seek alternatives for the freight they send up and down Europe’s second-largest river.
This graphic uses data from the German Federal Waterways and Shipping Administration (WSV) compiled by Olivier Lejeune to show 20 years of water levels at one notorious shallow point at Kaub, between Mainz and Koblenz.
How Important is the Rhine?
Around 195 million tons of cargo are shipped on German rivers each year—mostly on the Rhine.
Flowing from the Swiss Alps to the North Sea, the Rhine links German and Swiss industries with the Dutch city of Rotterdam, Europe’s biggest port. Its role in the continent’s economy traces back to the Roman Empire and early medieval trade.
The Rhine river is an important shipping route for many products like coal, gasoline, heating oil, chemicals, car parts, food, and thousands of other goods. However, when water levels drop, cargo vessels need to sail with a reduced load, so they don’t run aground.

In 2018, the Rhine waterway was shut for goods transport for a total of 132 days due to severe drought.
Due to an unusually hot and dry summer in Europe, the low water levels are emerging earlier than usual, with the lowest water levels typically recorded in September or October. Water levels at the chokepoint of Kaub, near Frankfurt, fell to 32 cm in depth on Monday, August 15, 2022.
The European Space Agency captured part of the Rhine River near Cologne – showing the stark difference between August 2021 and August 2022.

The Copernicus Sentinel-2 mission captured part of the Rhine River near Cologne—showing the stark difference between August 2021 and August 2022.
The low water levels are adding to Europe’s energy crisis, sparked by the Russian invasion of Ukraine. Barge rates to ship fuel from Rotterdam to Basel, Switzerland, are near an all-time high. The closure of the Rhine could disrupt 400,000 barrels a day of oil-product trade.
The Impact of Climate Change
Effects of climate change are modifying the discharge pattern of the Rhine and its tributaries, according to the International Commission for the Protection of the Rhine.
Periods with floods or low flow are expected to become more frequent and more distinct. Floods may be higher and last longer. In addition to navigation issues, the low flow may affect water supply and the quality of groundwater.

All the Metals We Mined in One Visualization
Metals are a big part of our daily lives, found in every building we enter and all devices we use.
Today, major industries that directly consume processed mineral materials contribute 14% of the United States economy.
The above infographic visualizes all 2.8 billion tonnes of metals mined in 2022 and highlights each metal’s largest end-use using data from the United States Geological Survey (USGS).
Iron Ore Dominance
Iron ore dominates the metals mining landscape, comprising 93% of the total mined. In 2022, 2.6 billion tonnes of iron ore were mined, containing about 1.6 billion tonnes of iron.
Metal/Ore | Quantity Mined in 2022 (tonnes) | % of Total |
---|---|---|
Iron ore | 2,600,000,000 | 93.3% |
Industrial metals | 185,111,835 | 6.6% |
Technology and Precious Metals | 1,500,008 | 0.05% |
Total | 2,786,611,843 | 100% |
Percentages may not add up to 100 due to rounding.
Iron ores are found in various geologic environments, such as igneous, metamorphic, or sedimentary rocks, and can contain over 70% iron, with many falling in the 50-60% range.
Combined with other materials like coke and limestone, iron ore is primarily used in steel production. Today, almost all (98%) iron ore is dedicated to steelmaking.
The ore is typically mined in about 50 countries, but Australia, Brazil, China, and India are responsible for 75% of the production.
Because of its essential role in infrastructure development, iron ore is one of the most crucial materials underpinning urbanization and economic growth.
Industrial Metals
Industrial metals occupy the second position on our list, constituting 6.6% of all metals mined in 2022. These metals, including copper, aluminum, lead, and zinc, are employed in construction and industrial applications.
Aluminum constituted nearly 40% of industrial metal production in 2022. China was responsible for 56% of all aluminum produced.

In the second position is chromium, which plays a primary role in rendering stainless steel corrosion-resistant. South Africa led chromium production, accounting for 44% of the total mined last year.
Technology and Precious Metals
Despite representing less than 1% of all the metals mined, technology metals have been on the news over the last few years as countries and companies seek these materials to reduce carbon emissions and improve productivity.
Technology and Precious Metals | 2022 Mine Production (tonnes) | % of Total |
---|---|---|
Tin | 310,000 | 20.7% |
Rare Earth Oxides | 300,000 | 20.0% |

They include lithium and cobalt, used in electric vehicles and battery storage, and rare earths, used in magnets, metal alloys, and electronics. Many of them are considered critical for countries’ security due to their role in clean energy technologies and dependency on other nations to supply domestic demand.
However, despite increasing interest in these metals, they are still behind precious metals such as gold and silver regarding market size.
The gold market, for example, reached $196 billion in 2022, compared to $10.6 billion for the rare earths market.

Visualizing Mining’s Footprint in British Columbia
Mining represents 7% of British Columbia’s GDP despite only accounting for 0.04% of the land use.

Visualizing Mining’s Footprint in British Columbia
British Columbia is considered a global leader in the development of socially and environmentally responsible resources.
An estimated 54% of the province’s total land is protected, making it one of the world’s greenest mining hubs.
This graphic by the B.C. Regional Mining Alliance (BCRMA) details mining’s footprint in the province.
A Tier 1 Jurisdiction for Mining
British Columbia covers almost 95 million hectares (234 million acres), more than any European country except Russia, and more than any U.S. state except Alaska.
As the largest mining province in Canada, BC registered $18 billion in revenue from the industry in 2022.
British Columbia stands as Canada’s sole producer of molybdenum, which finds applications in metallurgy and chemistry. Additionally, B.C. is the country’s leader producer of copper and steelmaking coal, besides gold and silver.
At the heart of British Columbia’s mining industry lies the Golden Triangle, one of the hottest mineral exploration districts in the world.
More than 150 mines have operated in the area since prospectors first arrived at the end of the 19th century. The region alone is endowed with minerals worth more than $800 billion.
How Green is B.C. Mining
Mining represents 7% of the province’s Gross Domestic Product (GDP), despite only accounting for 0.04% of the land use. In comparison, farmland demands 3% of the land, bringing $2.1 billion (0.8%) per year.
Land Use in B.C. | Revenue (2022, CAD $) | |
---|---|---|
Mining | 0.04% | $18.0 billion |
Oil & Gas | 0.4% | $9.5 billion |
Infrastructure | 1% | $25.0 billion |
Farmland | 3% | $2.1 billion |
Forest | 62% | $13.3 billion |
Mining operations are also supported by a stable, transparent, and effective policy environment. The province ranked as the world’s least risky for mining in 2017 and 2018.
In addition, mineral exploration has received ample support from local Indigenous communities. Today, mining accounts for over two-thirds of all indigenous people employed in the extractives sector.
According to the International Energy Agency, up to six times more minerals and metals will be needed by 2040 to accelerate the energy transition.
In this scenario, British Columbia is well positioned to support the transition to a low-carbon future and make a significant contribution to climate action.
The BCRMA is a strategic partnership between indigenous groups, industry, and government representatives that aims to promote B.C.’s mining opportunities internationally.
