Animated Map: U.S. Droughts Over the Last 20 Years

The Western U.S. is experiencing one of the worst recorded droughts in the last 20 years.

Temperatures from California to the Dakotas are currently hovering around 9-12°F above average—but how bad is the situation compared to past years?

This animated map by reddit user /NothingAbnormalHere provides a historical look at droughts in the U.S. since 1999, using data and graphics from the U.S. Drought Monitor (USDM).

What is the U.S. Drought Monitor?

Over the last two decades, the USDM has been tracking, measuring, and comparing droughts across America.

While droughts can be difficult to classify and standardize, there are various factors that can be used to gauge when a region is experiencing drought. These include measurements of snowpack levels, soil moisture, and recent precipitation.

To track these conditions (and make sense of them), the USDM synthesizes data from a plethora of meteorological sources, including the Palmer Drought Severity Index and the Standardized Precipitation Index.

From there, conditions are broken down into categories, ranging from D0 (abnormally dry) to D4 (Exceptional Drought). A map is released each week that shows which states are experiencing drought, and to what degree.

Where Are The Most Drought-Prone Areas?

According to a map created by climatologist Becky Bolinger (which is published on Drought.gov), Arizona and Nevada are the most historically drought-prone states—the two have experienced drought more than 50% of the time tracked by the USDM.

Most Drought-Prone States

California is high on the list as well, with the state experiencing drought at least 40% of the time.

As the historical data shows, the West is no stranger to droughts. However, this year’s drought has become particularly worrisome because of its intensity and breadth.

Right now, more than a quarter of the West is experiencing a D4 level drought—a new record. To help put things into perspective, here’s a look at how much overall land area in the West has been in drought, since 2000:

West Percent Area in U.S. Drought

When a region is experiencing a D4 drought, possible impacts include:

  • Water Scarcity
    Lower reservoirs, combined with decreased snowpack lead to water shortages.
  • Crop losses
    Water shortages mean less water for fields, which can lead to acres of fallow (unused) farmland.
  • Wildfires
    Dry conditions and lack of moisture increase the risk of wildfires.

Is This the New Norm?

This record-breaking drought is wreaking havoc across the West. In California, reservoirs have about half as much water as they usually do, and crop failures are happening across Colorado.

The worst part? Some experts believe that this could be the new normal if human-driven climate change continues to increase average temperatures across the globe.

Ranked: The World’s Top Cotton Producers

As the most-used natural fiber, cotton has become the most important non-food agricultural product.

Ranked: The World’s Top Cotton Producers

Cotton is present in our everyday life, from clothes to coffee strainers, and more recently in masks to control the spread of COVID-19.

As the most-used natural fiber, cotton has become the most important non-food agricultural product. Currently, approximately half of all textiles require cotton fibers.

The above infographic lists the world’s top cotton producers, using data from the United States Department of Agriculture.

Fancy Fabric

Originating from the Arabic word “quton,” meaning fancy fabric, cotton is a staple fiber made up of short fibers twisted together to form yarn.

The earliest production of cotton was around 5,000 B.C. in India, and today, around 25 million tons of cotton are produced each year.

Currently, five countries make up around 75% of global cotton production, with China being the world’s biggest producer. The country is responsible for over 23% of global production, with approximately 89 million cotton farmers and part-time workers. Cotton’s importance cannot be understated, as it is the primary input for the Chinese textile industry along with many other nations’ textile industries.

🌐 Other 4,059,0004,282,000
Total24,271,00025,155,000

The United States is the leading global exporter of cotton, exporting three-fourths of its crop with China as the top buyer.

Despite its importance for the global economy, cotton production faces significant sustainability challenges.

The Controversy Over Cotton

Cotton is one of the largest users of water among all agricultural commodities, and production often involves applying pesticides that threaten soil and water quality.

Along with this, production often involves forced and child labor. According to the European Commission, child labor in the cotton supply chain is most common in Africa and Asia, where it comes from small-holder farmers.

In 2020, U.S. apparel maker Patagonia stopped sourcing cotton from the autonomous territory of Xinjiang because of reports about forced labor and other human rights abuses against Uighurs and other ethnic minorities.

L Brands, the parent company of Victoria’s Secret, has also committed to eliminating Chinese cotton from its supply chain. Whether these changes in supply chains impact China’s cotton production and its practices, cotton remains essential to materials found across our daily lives.

Mapped: Where Does Our Food Come From?

Did you know that over two-thirds of national crops originated from somewhere else? Over time the food that built national diets has evolved.

Where Does Our Food Come From?

Did you know that over two-thirds of national crops originated from somewhere else?

Humans have been selecting and growing crops for specific traits since the origins of agriculture some 10,000 years ago, shaping where and what crops are grown today.

Now our food system is completely global and many of the world’s top producers of staple crops are in countries far from their historical origin. For example, Brazil is now the largest soybean producer in the world, though the crop is originally from East Asia.

The above infographic by Brazil Potash shows the historical origins of crops before they were domesticated across the globe and the main producers of our staple crops today.

Producers Of Staple Crops Today

Staple crops are those that are the most routinely grown and consumed. These can vary between countries depending on availability.

In 2020, sugarcane, maize, wheat, and rice made up around 50% of global crop production.

But when the production and distribution of staple crops are threatened, the consequences can be felt globally. Let’s take a look at the countries that were the top three producers of some of our staple crops in 2020.

CropCountryPercentage of Global Production
Sugar Cane 🇧🇷Brazil 40.5%
Sugar Cane🇮🇳India 19.9%
Sugar Cane🇨🇳China 5.8%
Maize🇺🇸U.S. 30.9%
Maize🇨🇳China 22.4%
Maize🇧🇷Brazil 8.9%
Wheat 🇨🇳China 17.6%
Wheat🇮🇳India14.1%
Wheat🇷🇺Russia11.3%

As you can see from the data above, Brazil is the world’s largest producer of sugarcane and one of the top three producers of maize.

The Future of Food Security

Global food security depends on staple crops and the countries that produce them. As the global population increases, so does the need to grow more crops.

The FAO estimates that by 2050 the world will need to increase its food output by around 70% in order to feed an ever-growing population.

Early food security solutions were transplanting crops from other regions to supplement diets. Now crop yields must increase as the next evolution in strengthening our food security. Fertilizers are a vital step in this process and are an essential ingredient in the future of global food security. They provide vital nutrients that increase crop production and strengthen nutrition security.

Brazil Potash extracts vital potash ore from the earth for it to return to the earth as fertilizer, fortifying food and helping to maintain continuous growth in the agricultural sector.
