For the study, the researchers gathered a long - term data set of residential lawn - watering frequency and lawn - watering behaviors, determined the scale of weekly lawn - watering frequency with water restrictions alone, and tested to determine if adding the weather - based conservation strategy could improve
lawn irrigation efficiency and water savings over water restrictions alone.
The search has spanned the gamut from funding research, investing in expensive solutions like desalination plants, toying with the idea of recycling wastewater, imposing water - use restrictions, letting
lawns go dry and experimenting with
irrigation efficiency techniques for the crops that feed the country.
