Category — Water – Greywater
The system, known as aquaponics, uses less water than traditional soil planting because very little water is lost to evaporation and none is absorbed into the ground.

But for small farms nestled between city streets, saving water means recycling it — and finding new ways to keep plants alive without wasting the precious liquid.
Unlike the large industrial farms that give California its reputation as the salad bowl of the nation, urban farmers don’t have to let fields sit fallow to reduce water use. The small-scale operations leave room for more creative approaches to drought-friendly growing practices. For those producing and selling food in the city, the drought has provided opportunities as well as obstacles.

If all the lawns in this particular neighbourhood were replaced with crops, Johnson and his colleagues estimated that around 37% of the local population would be provided with all their vegetable needs for the year, assuming a 150-day growing season and a density of around 5000 people per square kilometre.

“We estimated that the water demand could increase by more than 50% if urban agriculture were scaled to a significant degree,” said Johnson, who published the findings in Environmental Research Letters (ERL). “Water-smart agriculture – drip irrigation, rain-water harvesting and the like – would help manage the additional water demand and should be encouraged, particularly in regions experiencing water stress.”

Jesus Santillan agreed to contribute rainwater flowing off his home’s roof to the garden and fruit orchard next door in the 2100 block of N. 17th St.
A cistern will collect rain from downspouts until his neighbor, Walnut Way Conservation Corp., taps into it for the crops. Raspberry bushes line one edge of the garden where spinach, sugar snap peas and peppers are thriving in early June.

Shrinking soil. Vanishing rivers. The global food supply at stake… Drought is silently strangling our country, and the battle is just beginning.

Thirsty Land is a documentary film that tells the story about extreme drought, agriculture, & water rights in the United States and how these challenges impact farmers, local communities, and ultimately the global food supply. The depleted water resources in the American Southwest is one of the most urgent challenges of the 21st century facing agriculture and growing urban communities. The drought on this region has local, national, and global impacts not only for the present, but also for future generations.

The great Central Valley sells far more than $40 billion in crops yearly, making California the biggest ag state in the nation. It provides more than a third of the country’s vegetables and two-thirds of its fruits and nuts.

But the more altruistic — and accurate — part of the ad, aired by the California Farm Water Coalition, was its effort to educate those who shower and water their lawns with abandon about the toll the drought already has taken on the vast and now stunningly dry Central Valley.
“In farm country, where hundreds of thousands of acres have already been shut down because of the drought, thousands have lost their jobs,” the narrator said. “For those who can’t afford to feed their families anymore, the local food banks are struggling to keep up with demand.”

Lessons Learned and the Potential of Improved Water Management

2014. 60 pages
The purpose of this paper is to synthesize available knowledge and lessons learned from past experiences in promoting kitchen or home gardens, with a special emphasis on water management. The paper has been prepared based on an extensive desk study. It focuses on gardens whose primary purpose is production of food and, at times, growing herbs and spices for home consumption.

“We’re so used to Southern California having these beautiful, lush lawns and palm trees and seasonal flowers,” she told me by phone from Culver City, a suburb of Los Angeles, where she is general manager at a landscaping business called A Greener Tomorrow. But now, because of the drought and new water regulations, “I’m telling you, all I see is Arizona and Las Vegas.”
“Who’s going to be willing to pay?” she said. “You can’t maintain a lawn!”

California mandatory water restrictions include replacing 50 million square feet of lawns with drought-tolerant landscaping
‘This historic drought demands unprecedented action’

California’s ongoing drought isn’t letting up. As a result, Governor Edmund Brown announced today that California will enforce statewide water restrictions for the first time in the state’s history. The actions are meant to reduce the state’s water usage by 25 percent, the governor said in a statement.
“Today we are standing on dry grass where there should be five feet of snow,” Governor Brown said. “Therefore, I’m issuing an executive order mandating substantial water reductions across our state.”

Urban farming could improve food security but also increases the competition between urban and rural water needs.

South and East Asia comprise 49 percent of urban irrigated croplands and 56 percent of the non-urban irrigated areas globally. These two regions account for 26 percent of urban rain-fed croplands and 22 percent of non-urban rain-fed croplands.
Drechsel says, “The study documents that 70 percent of households in developing countries are engaged in some kind of farming and food production and challenges the notion that food production, far from being a rural phenomenon, is commonly occurring within cities.”

Linking urban water management more closely to urban farming has the potential to increase food security, water productivity, and community health, while reducing chemical fertilizer use, long-distance food and water imports, and related greenhouse gas emissions at the same time.

Yet a surprisingly large share of the world’s cropland is found not in rural areas, but within cities and their immediate surroundings. Some 456 million hectares (1.13 billion acres) of land is cultivated directly in cities or within 20 kilometers (12.4 miles) of an urban perimeter, according to a recent study conducted by researchers at the International Water Management Institute in Colombo, Sri Lanka, the University of California-Berkeley and Stanford University, and published in the journal Environmental Research Letters.

Gerlach, Nevada is a small village situated next to the Black Rock desert (well known because of the Burning Man festival).
Gerlach, Nevada is a small village. At the turn of the century the town still inhabited up to 900 people, but when the nearby gypsum plant closed down in 2011 and economy went down in the region and people started to move away and presently the town inhabits 100 people. Eight years ago schoolteacher Elizabeth Jackson and her colleagues started an educational community school garden and greenhouse project in this barren environment.

The severity of California’s drought continues to shock, with the latest example coming courtesy of NASA.
The space agency’s two Gravity Recovery and Climate Experiment, or GRACE, satellites have been been in orbit since 2002, making highly sensitive measurements of Earth’s gravity field. Variations in the gravity field can be caused by a number of factors, including the amount of water stored underground in soil and rocks.
