The Okavango Wilderness Project is working to safeguard a watershed crucial to one of the planet’s last wetland wildernesses.
National Geographic and Jigsaw Productions present Parched, a three-part series narrated by Academy Award winning filmmaker Alex Gibney that investigates water wars from West Virginia and Michigan to Syria and India. From the producers of the feature documentary Water & Power, a California Heist, this companion series explores the corporate, political and social interests that are responsible for our water limited future.
Introduce students to explorers passionate about freshwater issues
Encourage students to learn more about freshwater with these references
Agriculture is the art and science of cultivating the soil, growing crops and raising livestock.
An aquifer is an underground layer of water-bearing rock. Water-bearing rocks are permeable, meaning that they have openings that liquids and gases can pass through.
The Earth’s natural resources include air, water, soil, minerals, plants, and animals. Conservation is the practice of caring for these resources so all living things can benefit from them now and in the future.
Deserts are areas that receive very little precipitation.
Drought is an extended period of unusually dry weather when there is not enough rain.
A flood happens when water overflows or soaks land that is normally dry. There are few places on Earth where people don’t need to be concerned about flooding.
Groundwater is all the water found underneath the Earth’s surface.
Hydroelectric energy is power made by moving water. “Hydro” comes from the Greek word for water.
To irrigate is to water crops by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone.
A lake is a body of water that is surrounded by land. There are millions of lakes in the world.
The place where a river enters a lake, larger river, or the ocean is called its mouth.
Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants.
Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere before precipitating.
Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets.
A reservoir is an artificial lake where water is stored.
A river is a large, natural stream of flowing water. Rivers are found on every continent and on nearly every kind of land.
The place where a river begins is called its source. River sources are also called headwaters.
A stream is any body of flowing fluid. The most familiar type of stream is made of water, although streams can also be made of air, lava, electricity, or any other fluid.
The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere.
The water table is a line beneath the surface of the Earth.
A watershed is an entire river system—an area drained by a river and its tributaries. It is sometimes called a drainage basin.

Droughts can cause a variety of problems to local communities, including damage to ecosystems, crops, and a shortage of drinking water.
From "Cowtown" to a natural gas boom amid a water shortage: sustainability can happen in unexpected places.
Take an aerial tour of one of California’s drought-stricken landscapes in this clip from Years of Living Dangerously.
Discover the source of the Nile with real-life visuals and animated maps.
Freshwater is a precious resource worldwide. In the small Japanese village of Harie, residents use a unique method to keep their fresh water clean and clear. Watch this video to discover this rather fishy system.
