Urban Farming and Water Conservation: A Way of Life on the City Farm

It has been a banner year for water in California. The above-average precipitation and snowpack in 2017 have ended a five-year drought spell, leading Governor Jerry Brown to officially end the drought state of emergency last April for the majority of California counties. However, Californians know that this refreshing watery reprieve does not mean our conservation efforts stop here. With a draft plan in the making by the State Water Board appropriately dubbed “Making Water Conservation a California Way of Life,” the long term trend from this point on is efficient water use and drought preparedness, especially as we face climate change challenges.
How can we as urban farmers do our part to conserve water? Turns out there are a lot of ways that not only will help to save our beautiful state's water, but also help you build a healthier farm or garden with less work on your hands!

Rainwater Harvesting allows you to capture rainwater from roofs, collect it in a cistern for diversion to your landscape for supplemental irrigation. You should also observe your site's water runoff patterns and see how you can manage and maximize your runoff to deal with large rain events, stormwater runoff and infiltration around your site. Consider a rain garden!

- Dry Farming depends on the water stored in the soil from winter rains that plants can use in the spring as the weather warms. Plants rely on good soil moisture and deep roots to seek out this extra water without needing much supplemental irrigation. Grapes, potatoes, tomatoes, winter squash, fruit trees and grains can be dry-farmed.

And Remember:
- Deep watering wets entire root zones which promotes deeper root growth.
- Always water early in the morning to prevent daytime water loss through evaporation.
- Keep an eye on the weather! A refreshing rain or cool, cloudy day will extend the time between watering.
- Maintenance, maintenance, maintenance. Visually inspect your drip system regularly for breaks, leaks and missing pieces. If you don't, your plants will certainly let you know with plant diseases.
California's agricultural industry is the largest in the nation and abroad, carrying with that a great responsibility to protect and conserve our resources. Urban farmers are highly cognizant of this. They are some of the most innovative and conservation-minded folks out there who understand the fragility of our water supply and their role in being model stewards of our lands and waters.
