California has been facing a severe drought for the past four years, marking one of the worst water shortages in its history. This drought is classified as “exceptional,” the highest level of severity, and it’s causing significant challenges for the state.
California’s main reservoirs are only about 40% full, and some experts warn that there might be just a year’s worth of water left. Groundwater, which usually provides 40% of the state’s drinking water, isn’t a reliable backup. For years, California has been using more groundwater than can be naturally replenished, leading to both financial and environmental problems.
The drought is not just affecting tech industries and city dwellers; it also threatens California’s agriculture. Known as the “breadbasket of the world,” California is a major supplier of food in the U.S., producing half of the country’s fruits, nuts, and vegetables. Some crops, like almonds and walnuts, are grown almost exclusively in California.
Growing these crops requires a lot of water. For instance, it takes five gallons of water to grow a single walnut and nearly 1,800 gallons for a pound of beef. Agriculture uses 85% of California’s water, making the drought a critical issue for food production.
The drought isn’t just a California problem. The U.S. is a major exporter of corn, soybeans, and wheat, mainly grown in the Midwest and Great Plains. Climate change studies suggest that America could face a “mega drought” in the future, potentially lasting much longer than the Dust Bowl of the 1930s.
Researchers have used tree rings and climate models to predict that there’s an 80% chance of a severe drought in the Plains and Southwest between 2050 and 2100.
While these predictions may seem distant, California is hoping for enough rain in the coming years to alleviate the drought. If not, cities might need to consider solutions like recycling water or building desalination plants to make seawater drinkable.
Meanwhile, it’s important to appreciate the food we have and hope for better weather conditions.
Water scarcity is a global issue, with nearly a million people dying each year from diseases caused by unsafe water. As droughts become more common, clean water is becoming a precious resource. This raises important questions about whether water should be considered a human right and made accessible to everyone.
What do you think? Should Californians reduce their water usage to help manage the drought? Share your thoughts and stay informed about these critical issues.
Imagine you are living in California during this severe drought. Create a plan to reduce your household’s water usage by 20%. List specific actions you and your family can take, such as shorter showers or using drought-resistant plants in the garden. Share your plan with the class and discuss which actions are most effective.
Research the pros and cons of building desalination plants in California. Form two groups in class: one supporting desalination and the other opposing it. Prepare arguments and hold a debate. Consider factors like cost, environmental impact, and long-term sustainability in your discussion.
Create an interactive map showing the areas in California most affected by the drought. Use online tools to highlight regions with the most severe water shortages and the impact on agriculture. Present your map to the class and explain how the drought affects different parts of the state.
Use an online water footprint calculator to estimate how much water is used in your daily activities, including food consumption. Reflect on the results and write a short essay on how your personal water usage compares to the average Californian’s. Suggest ways to reduce your water footprint.
Write a short story imagining a day in your life without access to water. Describe the challenges you face and how you adapt to the situation. Share your story with the class and discuss the importance of water conservation and management.

For the past four years, California has been experiencing a significant drought, the worst it has seen in a long time. Just how serious is the situation? Quite serious.
Hi everyone, Julia here for DNews. The Golden State is currently facing an exceptional drought, classified as the highest category. This is the worst drought since record-keeping began over a hundred years ago, and water is in short supply. The state’s main reservoirs are at an average of only 40 percent capacity, and some reports indicate that California may have only a year’s supply of water left in those reservoirs. Groundwater is not a reliable option either; in a normal year, 40 percent of the state’s drinking water comes from underground sources. However, for too long, California has been extracting more water than can be replenished, which is a significant issue—financially and environmentally.
Over-pumping in the middle of the last century caused parts of California’s Central Valley to sink by 28 feet and resulted in over a billion dollars worth of damage. But it’s not just tech professionals and content creators who are affected; if the drought continues, we may have to say goodbye to some of our favorite foods. California is known as the breadbasket of the world and is the fifth largest supplier of food and agricultural commodities in the U.S. The Central Valley farms produce up to half of our fruits, nuts, and vegetables, and it exclusively produces 70 percent of America’s greens. Some crops, like almonds, artichokes, olives, pistachios, pomegranates, raisins, and walnuts, are not grown anywhere else in the U.S.
Unfortunately, feeding the country and much of the world leaves the state in a precarious position. It takes a significant amount of water to grow some popular foods. According to a study published in Hydrology and Earth System Sciences, it takes five gallons of water to grow one walnut, nearly five and a half gallons for one head of broccoli, and half a gallon for a single strawberry. The EPA estimates that it could take 1,800 gallons of water for a single pound of beef. All of this agricultural activity consumes 85 percent of California’s water.
But the issue isn’t limited to California. The U.S. accounts for half of all the world’s corn exports, 40 percent of soybeans, and 30 percent of wheat, primarily grown in the Midwest and the Great Plains. A recent study published in the journal Science Advances suggests that, due to climate change, America could face a mega drought. Remember learning about the Dust Bowl? There’s a chance we could experience a drought lasting three times as long in the future. Researchers analyzed climate history from tree rings and used 17 computer climate models to predict soil moisture over the next hundred years, estimating an 80 percent chance that the Plains and Southwest will face a severe drought between 2050 and 2100.
While that may seem far off, California is hoping for adequate rainfall in the coming years. If it rains sufficiently, things might improve. If not, cities may need to consider recycling water or building desalination plants. For now, enjoy your food and hope for rain.
Speaking of water, check out this video over at TestTube to learn if water is considered a human right. Every year, nearly a million people die from waterborne diseases due to unsafe water, while large parts of the world are experiencing unprecedented drought, making clean water a scarce resource. So, is water a human right, and should it be available to all?
