New paper: Modest water policy implementation could offset 30 percent of outdoor demand

July 14, 2020

A new paper in Sustainability Science finds that the use of alternative water supplies, such as rainwater harvesting and greywater use, could offset up to 30 percent of total outdoor water demand for the Phoenix Metropolitan Area under modest implantation of these policies.

The paper, Simulating alternative sustainable water futures, is the work of sustainability scientists David Sampson and Nancy Grimm, sustainability fellow David Iwaniac, UREX affiliate Elizabeth Cook and CAP LTER affiliate Melissa Davidson. The authors adapted ASU’s WaterSim tool to explore differences in water demand and supply, as influenced by runoff, rainfall, changes in land use and land cover, population growth and improvements in water use efficiency.

DCDC panel presents about stormwater managementOn December 5, Arizona State University’s Decision Center for a Desert City, a unit of the Julie Ann Wrigley Global Institute of Sustainability, hosted a panel discussion called "Innovative Stormwater Management: Resilience for Extreme Weather."

Directing more stormwater toward permeable surfaces so it trickles down into the aquifers beneath the city and catching more in rain barrels at homes were some of the ideas discussed. Multipurpose installations that collect water and can also be used as an amenity, like a park, or that protect from flooding while directing water towards aquifers are high on planners’ radars.

The discussion was part of the center’s Water/Climate Briefings, held on a regular basis. These briefings are a regular forum for the water-policy community, DCDC researchers and students to exchange knowledge and ideas.

If a fledging had caught a thermal in 1994 and spent the next two decades aloft above the U.S.-Mexico border, it would have witnessed some startling changes:

Mexican border cities like Ciudad Juarez and Tijuana ballooning as thousands streamed north to work in maquiladora factories, assembling products like garage door openers to be sold in the U.S. and Canada. Farmland around American cities morphing into suburbs. Mexican land being turned into agricultural fields.

What would not be visible from the air is the depletion of Mexican groundwater to grow the fruits and vegetables sent north.

Clouds reflect in the still waters of Lake MeadBeginning this summer, members of 12 rural communities throughout Arizona will get the chance to explore the past, present and future of water’s environmental and cultural impact in Arizona and beyond when the Smithsonian Institution's traveling exhibit Water/Ways visits their town. The first location to see Water/Ways is the Bisbee Mining and Historical Museum between June 2 and July 15.

Presented by Arizona State University and Arizona Humanities, the exhibit's journey continues through March 2020.

“Partnering with the Smithsonian on this project gave us an opportunity to expand the scope and impact of the work being done at the Decision Center for a Desert City to well beyond Phoenix and Arizona, to provide an informal educational experience in rural areas and reach an audience much broader in scope and background than we had previously been able to reach,” said David White, director of DCDC and a senior sustainability scientist at ASU’s Julie Ann Wrigley Global Institute of Sustainability.

Professor says crisis should serve as 'wakeup call'

DroughtAs Cape Town, South Africa nears “Day Zero” when authorities turn off the taps — expected in the first half of April 2018 — Senior Sustainability Scientist Dave White expresses the pressing need to adapt urban water systems to stresses like climate change.

White, who directs ASU's Decision Center for a Desert City, says that the causes of Cape Town's water crisis are familiar to water managers in water-scarce cities around the world – like Phoenix. These include limited supplies, dramatic population growth, aging and inefficient infrastructure, persistent drought, inadequate reservoir storage and climate change impacts.

Luckily, White provides a number of ways to improve water resilience. Among them are greater public engagement in water management planning and decision making, public and private investment in technology and infrastructure, rainwater harvesting, enhanced recycling and reuse of wastewater, cross-sector conservation and demand management, and development of new renewable supplies where feasible.

Water management in Brazil

December 31, 2017

Members of DCDC meeting with scientists, managers, policymakers and other stakeholders in Pernambuco, BrazilOne of the most pressing global challenges for sustainable development in the era of the Anthropocene is freshwater management. Water is a fundamental human necessity and essential to improve social equity, promote broad economic development and protect the functioning of the earth system.

That’s why ASU’s Decision Center for a Desert City collaborated with scientists, managers, policymakers and other stakeholders in Pernambuco, Brazil – to build local capacity to manage existing and future water resources efficiently, sustainably and equitably. Together, the team developed modeling tools and a decision support system that prepares users for whatever water scenarios come their way.

Senior Sustainability Scientist Dave White, who directs ASU's Decision Center for a Desert City, delivered his ideas for staying afloat in a March 2017 KED Talk. He demonstrated how the lessons he learned while rafting the Colorado River in 1998 are applicable to today's proverbial water rapids – namely drought, climate insecurity, population growth and overallocation.

"The solutions to these problems will require courage, skilled and experienced leadership," says White, "....and the recognition that the vitality of the American West depends on everyone paddling together."

Visiting author points out leaks in common water myths

Receding water reveals the decay on the lake bed of Lake MeadIn his January 2017 lecture "How Much Water Does Arizona Need?," author and journalist John Fleck drew from over two decades of reporting on western water issues to offer a surprising perspective on challenges unique to the region.

Fleck, who serves as director of the water resources program at the University of New Mexico, explained how cooperation and innovation have enabled the Southwest to grow and prosper in the face of diminished water supplies – not conflict, as some believe. That rich communities take water from poor communities was another notion Fleck labeled as a myth, saying that ideas like these make it difficult to establish collaborative relationships.

The lecture, co-sponsored by Decision Center for a Desert City, was part of an ongoing ASU conversation the examines water from a range of disciplines – from science and conservation to law and policy.

Teaching water lessons on Main Streets across America

Birds sitting on a damThe "Museum on Main Street," conceived by the Smithsonian Institution, brings exciting exhibits to small towns throughout the United States. Among these exhibits is WaterSim, an interactive water management tool developed by researchers at ASU's Decision Center for a Desert City.

According to School of Sustainability Dean Chris Boone, “WaterSim America is a great platform to educate the broader public on what they can do as individuals and groups to manage water in ways that lead to positive change.”

WaterSim achieves this by simulating the impacts of factors like population growth and drought on a given state's water supply and demand. Users then respond to challenges by selecting policies that steady their state’s water system.

Panelists discuss water in front of audience“We have more interest, more data, and more planning tools than we’ve ever had."

This was a sentiment expressed by James Eklund – director of the Colorado Water Conservation Board – at Decision Center for a Desert City's annual keynote on March 3, 2016.

The discussion, titled "A Conversation about Solutions for Water Sustainability in the Colorado River Basin," also included Eklund's Arizona counterpart Tom Buschatzke – director of the Arizona Department of Water Resources.

The two water chieftains, moderated by sustainability scientist Wellington “Duke” Reiter, explained that Arizona and Colorado have an ample water supply as the result of very careful planning and conservation.

They stressed that this fact should not keep residents of the states from viewing water as the precious resource it is.
