One way to celebrate World Water Day is to learn more about water and sanitation and how water quality and quantity vary by nation. The United Nations has a powerful tool called UN Water that provides an interactive map with snapshots of each country with a ranking of various water quality and water treatment issues.
In the United States, we are fortunate that a large majority of the US population has a safe, sanitary source for drinking water and that wastewater is safely treated. This is not the case everywhere.
Another way to celebrate World Water Day is to share the information that you learn with other people. Sharing knowledge is an important way to help spread awareness of the need for access to clean water. You can also share this information through social media.
Key messages for World Water Day 2025
Glaciers are melting faster than ever. As the planet gets hotter due to climate change, our frozen world is shrinking, making the water cycle more unpredictable and extreme.
Glacial retreat threatens devastation. For billions of people, meltwater flows are changing, causing floods, droughts, landslides and sea level rise, and damaging ecosystems.
Glacier preservation is a survival strategy. We must work together to reduce greenhouse gas emissions and manage meltwater more sustainably for people and the planet.
Annually, the United Nations celebrates March 22nd as World Water Day. World Water Day celebrates water and raises awareness of the 2.2 billion people living without access to safe water. The day is about taking action to tackle the global water crisis, and remembering what a vital role water plays for all of humanity. This year, the theme of World Water Day is “SAVE OUR GLACIERS,” with a focus on glacier preservation. Therefore, no matter where we live, glaciers are critical to our water future.
“I don’t live near a glacier. Why should I care about glaciers?”
Glacier Facts: 70% of the Earth’s fresh water exists as snow or ice. Around 10% of the Earth’s land area is covered by glaciers or ice sheets.
Glaciers are part of the “cryosphere” which impacts every living being on the planet. The word “cryosphere” originates from the Greek word ‘kryos’ for frost or ice cold. The cryosphere extends across the globe and can appear seasonally (like snow in Iowa) or be permanently present in most parts of the world. The snow, glacier, permafrost, and frozen ground are significant storage and sources of freshwater, sustaining ecosystems and supporting livelihoods in and far beyond the regions where these are located. While you watch the video below you will learn about the cryosphere and how it’s changing.
Undeniably, all living beings depend directly or indirectly on the cryosphere. For example, as all major rivers originate from mountains, the mountain cryosphere plays an important role in providing and regulating freshwater resources for around half of the world’s population. Furthermore, alterations and loss of critical snow and ice are increasing the risk of other hazards.
The state of cryosphere is also a useful indicator for climate variability and change. Therefore, improved monitoring is critical to understand Earth’s weather, climate, and water cycles. The cryosphere, its changes, and its impacts have received increased attention in recent years, creating a demand for authoritative information on the state of the world’s snow and ice resources.
As shown above in the video, glaciers are extremely important to help regulate the earth’s temperature. Glaciers, snow, and ice reflect much of the sun’s radiation into space (keeping those areas cooler), unlike the bare ground or open ocean water, which absorb the radiation (making them warmer). Glaciers also store freshwater and are an essential part of the water cycle.
On May 18, 1980, Mount St. Helens erupted, causing widespread devastation across the surrounding landscape. An infrared, false-color image, captured on August 26, 1986, by the Thematic Mapper sensor on Landsat 5, vividly illustrates the eruption’s aftermath. The image reveals the extensive damage caused by the eruption, including the vast areas of barren land and the destruction of dense forests. Disaster mapping is crucial in understanding the long-term environmental impact of natural and human-made disasters. It also aids in monitoring the gradual environmental recovery process.
Image 1: What’s going on in this picture? An Image from the lesson plan
This lesson teaches students about natural hazards and disasters from a global scientific perspective and also to help bring awareness to the natural hazards at their local level. By having local knowledge about natural hazards students are better prepared as they make choices in their communities. In the first activity, students learn important vocabulary words. the words will help students understand the difference between a natural hazard (environmental phenomena that have the potential to impact societies and the human environment) and a natural disaster (the negative impact following an actual occurrence of a natural hazard in the event that it significantly harms a community.)
Then students will use Mt. St. Helens as a case study to examine these ideas. Students will look at a satellite image taken shortly after the Mt. St. Helens volcanic eruption and be asked to tell what is going on in the image (see Image 1). To help reinforce the vocabulary concepts students can play an online game or complete a print handout (see Image 4).

Next, students will continue learning about Mt. St. Helens by completing a reading, “Devastation and Recovery at Mt. St. Helens,” on the NASA Earth Observatory website. They will also view a time-lapse video showing images from 1979-2016. Students can complete another short online quiz or printout to assess reading comprehension. To wrap up the Mt. St. Helens lesson, students will spend time usingGoogle Earth to explore the site of the volcano’s eruption. The teacher is encouraged to discuss how satellite imagery has been a major technological breakthrough for disaster management. It has allowed scientists a new way to monitor changes, which helps track hazards and disasters. Example: images before the eruption, in the aftermath (to assess the damage), and in the recovery phase. Share with students that the Landsat satellite has a new image every 16 days.
Transitioning to the second part of the lesson which is focused on identifying the most significant risks of natural disasters locally based on the local occurrence of natural hazards. It is important to emphasize that natural hazards can occur in any region of the country. While we can’t stop natural hazards from occurring, we can do our best to be prepared for them when they do occur.
One way we can be prepared for natural hazards is to know the greatest risks in our local community. The Federal Emergency Management Agency (FEMA) defines natural hazards as environmental phenomena that have the potential to impact societies and the human environment. FEMA created a web map of the United States that scores every location based on their risk of natural hazards and their community’s resiliency. The FEMA National Risk Index Map can help communities understand their natural hazard risks and their expected impacts during or after a disaster.

Therefore, to better understand these risks, students will learn about 18 common natural hazards, and then they will estimate which hazards they think are most likely to happen in your community. After talking with a partner and the class, students will be introduced to the FEMA National Risk Index website; please take a look at the lesson plan for more details. As the class wraps up, there will be a short discussion of emergency management careers. A final online game or printable quiz is available to test students’ natural hazards knowledge from the lesson.
As this year comes to a close, many people take time off for rest and celebration. Here are a few fun maps and StoryMaps that have some holiday themes or can help you plan for adventures in 2025.

It’s that time of year again! We are celebrating Geography Awareness Week! November 13-17, 2023
The History of Geography Awareness Week:
Thirty-six years ago, the National Geographic Society advocated to create Geography Awareness Week. Geography Awareness Week is a way to celebrate and raise awareness of geography, both as a discipline and as a part of daily life. The National Geographic Society felt the limited exposure to geography in American education was a dangerous deficiency. Without proper exposure to geography, students are unable to make effective decisions, understand geo-spatial and geo-political issues, or even recognize their impacts as global citizens. — see more at the National Geographic Website
