“Altitudes” reorients formerly disused ecologies for the production of local cash crops, organized vertically in the Selva Central region of Peru. Image courtesy Openfabric.

The coffee production industry is a “global economy with a local ecology,” says Francesco Garofalo of the landscape architecture studio Openfabric. The studio has a plan for a coffee-producing region of Peru that would align local cultivation practices with global distribution networks. Openfabric’s “Altitudes” plan steps back from coffee plantation monocultures to spread cash crop risk by encouraging production of a range of foodstuffs. The goal is to create more sustainable cycles of cultivation, production, and distribution.

The plan focuses on the Selva Central region of Peru, east of Lima, which straddles both the Andes and the Amazon River Basin. The local economy is intensely reliant on coffee production, but it’s a fragile and volatile market. Prices surge and plummet on a whim, vulnerable to small climatic shifts that can greatly affect yield. That makes life for the region’s coffee producers precarious.

And lately, temperatures in Selva Central have been rising because of climate change, causing (more…)

Development as usual is not cutting it in the era of climate change. A new interdisciplinary report released this morning by the American Society of Landscape Architects calls on public officials and private interests both to transform the ways they plan, design, and build at all scales to counter climate change, and it asserts that the most fundamental and potent mitigation policies and strategies are based in landscape solutions.

ASLA’s Blue Ribbon Panel on Climate Change and Resilience comprised 10 professionals—five of them landscape architects—who produced a slate of recommended policies and planning solutions to guide national and local leaders, as well as private-sector decision makers as they work to address climate change in several specific development arenas. That includes the protection of (more…)

FROM THE JANUARY 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Iwanuma is a quaint and quintessentially Japanese beach town on the Sendai Coast, a two-hour train ride north of Tokyo, in Miyagi Prefecture. Rolling sand dunes line the coast, and a thin forest of black pines spreads inland to a wide band of rice paddies and modest farmhouses. Like dozens of small communities along this stretch of coast, it’s been farmed for hundreds of years, left mostly to itself as Japan developed and urbanized.

When the Great East Japan Earthquake pushed a tsunami against the coastline on March 11, 2011, Iwanuma was washed over by waves that rushed inland for miles and destroyed almost everything in their path. The parts of Iwanuma inundated by the tsunami were mostly agricultural lands, but the death toll still reached an estimated 180 people. In all, more than 15,000 people died as a result of the earthquake and tsunami. Most drowned.

It was a devastating catastrophe for a country all too familiar with disasters, natural and human-made. But it was also something of an alarm to many people in seismically hyperactive Japan who have become newly energized by efforts to prevent similar destruction from the inevitable tsunamis of the future. One approach has gained considerable attention: the accelerated planting of “forest walls” as wave barriers. Hundreds of thousands of saplings have been planted (more…)

A retired cranberry bog inspires an innovative approach to wetland restoration.

FROM THE JANUARY 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

In 2005, Glorianna Davenport began to think about retiring the cranberry farm she owned in Plymouth, Massachusetts. In the late 1980s, the 600-acre farm was producing 1 percent of Ocean Spray’s cranberry harvest, but Davenport had become concerned about the amount of pesticides being used—and the way those pesticides were applied. “Because cranberries are grown on former wetlands, we had to farm with helicopters,” Davenport says. “And spraying chemicals from helicopters is not really great in a densely populated area.” Davenport, a visiting scientist at the MIT Media Laboratory, whose husband bought the cranberry farm in the early 1980s, could also see the handwriting on the wall for older cranberry farms, with new cultivars producing five times as many berries, farmed in places easier to access than wetlands and river bottoms. “The industry was changing pretty radically,” Davenport says. “The way we had been farming was really the legacy of another era.”

Davenport learned that a nearby cranberry farm had been restored back to wetlands—said to be the first project of its kind in the United States—and that she was eligible for assistance through the U.S. Department of Agriculture Natural Resources Conservation Service’s Wetlands Reserve Program, which pays farmers to take land out of production to preserve, restore, and enhance wetlands on their properties. The program was established by the 1990 Farm Bill. In 2008, Davenport decided to retire from MIT to undertake the restoration of Tidmarsh Farms. With federal and state funding in hand, she began working with the state’s Department of Fish and Game to pull together an interdisciplinary team of state and federal scientists and river, wetland, and other experts to help restore the bog at Tidmarsh Farms, an effort that took several years.

Ten thousand years ago, glaciers moved down across the northeastern United States, then retreated. As they did, big chunks of ice were left, forming (more…)

A custom geodesign process aims to help prototype solutions for the health of a rural watershed.

FROM THE NOVEMBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Sam Ziegler, a corn-and-soybean farmer in southern Minnesota, had a chance to try out a new geodesign tool that could change the way he plants his crops. “It’s always on your mind what you can do better, but it’s hard to physically take an acre or a hundred out of production just to try something,” Ziegler says. “You can’t afford it. But this computer model allows you to play with things and get an understanding of what potentially would be the ramifications and benefits of switching things around.” The tool, operated with a touchscreen, was developed by a team of University of Minnesota (UM) researchers from the fields of landscape architecture, urban planning, economics, and soil and water science.

In the fall of 2013, the research team brought together about 40 community members, including farmers and environmental advocates, who were interested in improving the health of the Seven Mile Creek Watershed near Mankato, Minnesota. The group participated in a series of workshops that culminated with their generating alternative scenarios using an interactive computer model of the watershed. This investigation was supported by background layers such as aerial photographs, parcel lines, and topographic data that would feel familiar to regular users of geographic information systems. Using a 55-inch touchscreen, participants could assign various agricultural land uses to the landscape, including conventional corn and soybeans and perennial prairie grasses. “Basically, it was like painting a map, with some boundaries,” Ziegler says.

Once participants settled on a design, the geodesign program would analyze its environmental performance around various factors such as (more…)

Technologist landscape architects rejoice—the November issue of LAM is packed with imagined scenarios, myth breakers, and tantalizing possible futures for urban design. Whether or not autonomous vehicles will allow for utopian cities of tomorrow depends on careful planning and policies today, says writer Brian Barth. And the future of autonomous vehicles might not look as green as we’re imagining. A new landscape by Ki Concepts on Honolulu’s Ford Island—site of the Pearl Harbor attack in World War II—weaves the richly layered history of the site into a sleek, cohesive design. And a new streetscape redesign by CRSA in the Sugar House business district of Salt Lake City turns a large thoroughfare into an inviting multimodal streetscape.

In Materials, Jane Berger discusses the stigma—and benefits—of the often-misunderstood bamboo. And in Tech, geodesign unites academics and agriculturists in the pursuit of the most optimal yield for their yearly crops. All this plus our regular Books, Now, and Goods columns. The full table of contents for November can be found here.

Marijuana wafts across the California landscape as legalization of recreational use approaches.

FROM THE OCTOBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Ed Rosenthal grows weed. He has for decades. The Oakland, California-based horticulturist, author, and activist is the go-to expert on home cultivation. He’s written more than a dozen books on the subject and the policies that surround medical marijuana and legalization. Their titles fall somewhere between what you’d see in your local nursery and your corner head shop: The Big Book of Buds (volumes one through four), Marijuana Garden Saver, and Marijuana Pest & Disease Control.

“Growing is addictive,” Rosenthal says with a laugh, and then quickly clarifies that the drug is not. “Given the right conditions and a sunny backyard, marijuana can be grown almost anywhere in California.” He speaks poetically about marijuana’s diverse morphology: It has male and female plants. Some are tall, some wide, and there are different strains like indica or sativa that range in color—like heirloom tomatoes—from absinthe yellow–green to maroon and deep purple. To cultivate cannabis for its THC (tetrahydrocannabinol) and psychoactive properties, only the female plants are grown. The male plants look a bit like wild mustard; the female plants are the ones that produce buds for consumption. “With humans and cannabis, the female is considered more beautiful,” he explains. “I have a bunch of marijuana plants growing, and they all look different, like six different varieties of a dahlia. Each plant is (more…)
