Center pivot irrigation Water is distributed by a system of sprinklers that move on wheeled towers in a circular pattern. This system is common in flat areas of the United States.
Lateral move irrigation Water is distributed through a series of pipes, each with a wheel and a set of sprinklers, which are rotated either by hand or with a purpose-built mechanism.
The sprinklers move a certain distance across the field and then need to have the water hose reconnected for the next distance. This system tends to be less expensive but requires more labor than others. Sub-irrigation Water is distributed across land by raising the water table, through a system of pumping stations, canals, gates, and ditches. This type of irrigation is most effective in areas with high water tables.
Manual irrigation Water is distributed across land through manual labor and watering cans. This system is very labor intensive.

By establishing domesticity, families and larger groups were able to build communities and transition from a nomadic hunter-gatherer lifestyle dependent on foraging and hunting for survival. Select from these resources to teach your students about agricultural communities. Technological innovations have greatly shaped agriculture throughout time.
From the creation of the plow to the global positioning system GPS driven precision farming equipment, humans have developed new ways to make farming more efficient and grow more food. We are constantly working to find new ways to irrigate crops or breed more disease resistant varieties.
These iterations are key to feeding the ever-expanding global population with the decreasing freshwater supply.
Explore developments in agricultural technology and its impacts on civilization with this curated collection of classroom resources. Freshwater is a precious resource on the Earth's surface. It is also home to many diverse fish, plant, and crustacean species. The habitats that freshwater ecosystems provide consist of lakes, rivers, ponds, wetlands, streams, and springs.
Use these classroom resources to help students explore and learn about these places. With the human population soaring out of control, agriculture must follow suit. But the innovations that boost crop yields carry ecological costs. Xeriscaping is the practice of designing landscapes to reduce or eliminate the need for irrigation. The Tigris River, which borders Mesopotamia in the Fertile Crescent, has been a key source of irrigation, power, and travel that dates back to the earliest known civilizations.
