These materials are part of a collection of classroom-tested modules and courses developed by InTeGrate. The materials engage students in understanding the earth system as it intertwines with key societal issues. The collection is freely available and ready to be adapted by undergraduate educators across a range of courses including: general education or majors courses in Earth-focused disciplines such as geoscience or environmental science, social science, engineering, and other sciences, as well as courses for interdisciplinary programs.

For the Instructor

These student materials complement the Water Science and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Water use trends in LA

The trend in total water use for the City of Los Angeles (Figs. 3 and 4) is interesting because, although the population has increased significantly since 1970, average demand has remained relatively constant between 600 and 700 million acre-ft per year. This is testimony to the effects of conservation and reuse because of source limitations (competing uses, drought) and rising costs. Economic downturns may also play a role. Certainly, one way to conserve water in LA is through limiting outdoor water use (car washing, landscaping/lawns). It is estimated that watering landscaping for individual homes is about 38% of total water use. Perhaps, like Las Vegas, LA should further encourage xeriscaping and graywater use for irrigating lawns and golf courses, but more on solutions in Module 8, Part 2 next week.
