Agricultural uses: Farming Water use #1 Agricultural uses: Farming # of farms has dropped!

Agricultural uses: Farming in AZ Water use #1 Agricultural uses: Farming in AZ The southern half of the state is good for year round crop growth in irrigated areas.

Water use – Sustainability triangle Industrial uses Economic: Arizona tourism industry brings $17.7 billion yearly. Social: The state has many golf courses, parks, and shopping locations. Environmental: The state’s golf courses and parks provide vegetation which reduces heat.

Water use #3 Personal use Every day uses: Homes, drinking water, swimming pools, lawns

How are residents encouraged to conserve lawn water use? Xeriscaping (native plants) Avoid watering during peak heat
