Iowa City’s Sustainability Showcase: Gaia’s Peace Garden Blooms As Model Urban Oasis

Tucked away at the end of a residential cul-de-sac in Iowa City, just south of Interstate 80 and growing suburbs, the daffodils, violets and hyacinth in bloom, among the peach, pear, cherry and apple blossoms, Blair Frank tends to the medicinal herb section at the privately-owned Gaia’s Peace Garden with the precision of an urban planner. Far from being a “vacant lot,” the eight-year-old Peace Garden initiative under Frank and his wife Mary Kirkpatrick’s tutelage has emerged as a nationally acclaimed sustainability showcase for Iowa City, transforming 1.1 acres of clay soil into a biodiversity hot-spot, a permaculture demonstrate site, a local food and medicinal herb oasis, and a blueprint for city staff and planners on how to incorporate green spaces and commons into neighborhood development. A solar energy panel powers a pump on a small waterfall as a renewable energy demonstration site; a stone labyrinth guides visitors around the Garden sections, where benches and places have been set up for meditation. “It’s a demonstration of some of the most forward-thinking and ecologically sound land management practices available,” said Jennifer Kardos, with the nonprofit Backyard Abundance. “But more importantly, it is place infused with love where community members can gather and imagine a more peaceful way of being in the world. It has been a place of refuge and deep healing for me personally.” Gaia’s Peace Garden has also become a beloved landmark for neighbors, offering a serene and safe place in the urban landscape to reconnect with nature, take a walk during lunch or quietly meet in the evenings. “We love the garden,” said Claudia Sartini-Rideout, whose next-door property overlooks the Peace Garden. “Many of the neighbors often bring their kids there. It is a beautiful and peaceful place, and we are glad it is in our neighborhood. Blair and Mary are great neighbors!” With more than 70 fruit trees, a berry and nut patch, an extensive vegetable garden, a medicinal herb garden, a nationally recognized monarch butterfly way-station of milkweed, nectar sources and shelter, Frank has worked with local groups and biodiversity experts to create the first botanical sanctuary recognized by the United Plant Savers in southeast Iowa.

Tesla’s parking lot is a nightmare hellscape.

You can’t fight what you can’t measure. But Davida Herzl has a solution: Her company, Aclima, builds sensor networks that monitor environmental impacts at a hyperlocal scale. Clients can deploy sensors on city streets, inside buildings, even on vehicles, to compile data on pollutants, carbon footprint, and more.

Think of it as a Fitbit for a planet trying to take more steps toward carbon reduction. In addition to working with the Environmental Protection Agency, Aclima has partnered with Google’s Street View fleet to map greenhouse gas emissions and air quality in California.

Herzl ultimately wants her sensor networks to create changes in behavior, both from large institutions and from individuals who can follow their lead. “One of the things we know is that emissions from non-electric vehicles influence climate change — but now we’ve learned that the proximity of my house to a freeway increases my health risk,” she says. “That can influence whether I choose to buy an electric vehicle or a nonrenewable-fuel-based vehicle … That personal moment motivates me every day.”

Workplace culture matters to Herzl, too: She sees Aclima’s multiracial, gender-diverse crew as part of a new vanguard in Silicon Valley dedicated to solving the world’s biggest problems through industry and innovation.

Chicago wants to dominate in renewable energy.

Contrary to what you may have heard, the reef isn’t dead — not yet. But aerial surveys show that 900 miles of the 1,400-mile-long reef have been severely bleached in the past two years.

Bleaching occurs when warm water causes stressed-out corals to expel symbiotic algae from their tissues; corals then lose their color and their chief source of food, making them more likely to die.

Last year’s El Niño–induced bleaching event was devastating, knocking out two-thirds of the corals in the northern section of the reef. We’d hoped that 2017 would bring cooler temperatures, giving the fragile ecosystem some much needed R&R.

Instead, temperatures on Australia’s east coast were still hotter than average in the early months of this year, and on top of that, the reef’s midsection took a hit from a big cyclone in March.

ARC Center of Excellence for Coral Reef Studies

This is the first time the reef has experienced back-to-back annual bleaching events. If this keeps happening, it’ll quash the reef’s chances for recovery and regrowth, a process that can take a decade or longer under normal conditions.

Under the abnormal conditions of climate change, though, there is little reprieve — unless we, y’know, address the root of the problem itself.
