Posts Tagged ‘Covering Climate Now’

BY JARED BREY

After two rare storms inundate Ellicott City, Maryland, the town tries to sort through what can be saved.

This week, LAM is joining more than 250 media outlets for Covering Climate Now, flooding the zone, as it were, with climate coverage in the run-up to the United Nations Climate Action Summit on September 23. Landscape and landscape architecture are deeply implicated in the future of climate progress, or a lack of it. Over the past decade, LAM has dug into climate issues of landscape in numerous dimensions, mapping the big resource picture as well as local attempts to fend off increasingly apparent hazards of global warming—from the procurement of materials to the integrity of the food supply chain. Each day this week we’ll bring you excellent stories from recent years that follow landscape architects acting and thinking about climate change and the landscape.

The Tiber-Hudson watershed, in Howard County, Maryland, drains three-and-a-half square miles of mostly developed land in and around Ellicott City, a historic mill town founded in 1772 on the banks of the Patapsco River. The terrain surrounding the town is steep. On the south side of lower Main Street, a series of mill buildings is packed alongside and astride the Tiber Branch, one of the watershed’s three main tributaries to the Patapsco. On the north side, old stone buildings are backed up to a hill made of granite bedrock. Rainwater flows downhill, east toward the river, and in Ellicott City, there’s nothing farther downhill than lower Main Street, the historic center of the town.

When I visited at the beginning of February, the sun was out and it was warm enough to leave my jacket in the car. Walking downhill into lower Main, where the street is narrower, the air temperature dropped and the shadows darkened. On my right, behind a row of boarded-up storefronts, I could hear the Tiber Branch rushing along parallel to Main Street. It smelled like a basement.

On the night of July 30, 2016, a storm rolled in and sat directly on top of Ellicott City, dropping 6.5 inches of rain in the watershed in just three hours. Water jumped the banks of the Hudson Branch uphill and flowed down Main Street, (more…)

Around a school in an arctic town, Cornelia Hahn Oberlander has made a landscape to withstand the prospect of a warming world.

The permafrost is melting in Inuvik, a flat delta town in the Northwest Territories, 2 degrees north of the Arctic Circle. You can see the drunken trees, leaning this way and that along the banks of the Mackenzie River. The Gwich’in and Inuvialuit—native people who make up 40 percent of the some 3,500 residents here—have to go farther out to hunt seals, because of the melting ice.

The caribou get stuck in the mud, instead of running across snow, as they migrate to their calving grounds north of Tuktoyaktuk, or Tuk, as people here say, on the coast of the Beaufort Sea. The lichen that has sustained them for millennia is getting crowded out by species that thrive in warmer temperatures.

Local people tell of landslides and collapsing banks along the Mackenzie River, or slumping—where the land simply caves in—on a road or in the forest. The pingos, or subterranean ice houses, may be melting up in Tuk, but most people have freezers anyway.

“Come, I want to show you where I sank into the permafrost that was melted,” Cornelia Hahn Oberlander, FASLA, the Canadian landscape architect, said one unseasonably cold day in July. (more…)

New technologies can reduce the environmental footprint of the most-used construction material.

Concrete in the 21st century promises to be a more sustainable material, and given the nine billion metric tons used globally each year, it must be. Portland cement, the binding agent in ordinary concrete, has a very high carbon footprint, resulting in just under one ton of carbon dioxide (CO2) released for every ton of cement produced. With 4.2 billion metric tons of the binder used each year worldwide, cement production is responsible for nearly 8 percent of total global carbon emissions. The high lime content of ordinary portland cement contributes about two-thirds of cement’s CO2 impact through the process of limestone calcination. The other one-third of CO2 released is from combustion of fossil fuels.

Technologies to improve the carbon footprint of concrete are currently in the early stages of development, but some, including carbon sequestration in concrete and substantial reductions of cement using energetically modified cement, are now commercially available. Concrete surface products for paving and walls to scrub air pollution, as well as new self-healing concrete products, are also worth investigating. We have heard about some of these innovations for a decade or more in the research community, but many are finally being brought to market—some more quickly than others. Europe is ahead of the United States in the adoption of these technologies, largely because of more rigorous clean air and carbon reduction initiatives.

New technologies in any field can take a long time to move from the laboratory to the marketplace, but (more…)

An ambitious forest restoration project in Ashland, Oregon, aims to reduce the risk that wildfire poses to residents—and their water supply.

Though the warning signs had been present for months, the bad news officially came in March 2018, when forecasters at the Northwest Interagency Coordination Center (NWCC) in Portland, Oregon, released their long-range forecast of the upcoming fire season. Though it varied from state to state, in Oregon, light snowpack and higher-than-average temperatures combined to create a highly combustible landscape. “I’m worried about the 2018 fire season,” John Saltenberger, the fire weather program manager at the NWCC, told a Portland television station.

It was discouraging news for a state that, like California and other western states, has seen a growing number of increasingly intense wildfires in recent years. According to Oregon Department of Forestry statistics, 69 percent of the state’s largest recorded wildfires have occurred in the past 20 years. The largest, 2012’s Long Draw Fire, scorched nearly 560,000 acres of predominantly federal land in the southeastern part of the state. In the geological age known as the Anthropocene, the current epoch might one day be known as the Era of Megafires. A megafire is typically defined as a single wildfire that exceeds 100,000 acres. Such fires are “nearly commonplace now,” says Chris Chambers, who for the past 15 years has served as the forest division chief for the City of Ashland, Oregon. “Whereas 20, 30 years ago, a 100,000-acre fire was unheard of.” (more…)

THE RISING TIDEWATER

Disparate but urgent efforts to address sea-level rise in the Virginia Tidewater, one of the country’s most important strategic centers, are striving to keep up with visible realities.

The first question that sprang to Ann C. Phillips’s mind soon after she moved to Norfolk, Virginia, in 2006 was, “Why, when it rains, does the whole place submerge?”

She wasn’t referring only to dramatic weather events, although Phillips, a retired rear admiral in the U.S. Navy, landed in Norfolk during a bumper crop of those: Norfolk saw more major coastal storms and hurricanes in the 2000s than in the four previous decades combined, according to the city government.

Harder to fathom were the floods caused by light rains and “blue sky floods” triggered by lunar tides. Tidal flooding affects low-lying areas of Norfolk nine times per year on average.

These more regular floods were unlike anything Phillips experienced growing up in Annapolis, Maryland. They’re an alarmingly routine part of life in Norfolk and the surrounding Hampton Roads area (more…)

The Paris Agreement on climate change, created by the consensus of 197 nations, went into effect in November 2016 and has enormous implications for the practice of landscape architecture. If adhered to by its signatories, the agreement signals the end of the fossil fuel era by midcentury, well within the life spans of many landscape architects currently practicing. Though it may seem wonderfully “green,” this energy transition poses profound questions for the practice of landscape architecture at a time when the discipline is needed more than ever. (more…)

A tall blond man is walking a Russian wolfhound along a stream. The stream is moving through beach sand into a large lagoon off the Kijkduin promenade in a seaside suburb of The Hague, Netherlands. It’s not quite beach season, and it’s blustery. Over scudding clouds the sun coming up is bright, but the gray sea is running fast and flecked with white, and the wind blows foam up the beach. Over the man’s shoulder are tall, reedy dunes and the tips of towering chimneys, billowing clouds of steam.

These chimneys, up to 575 feet high, rise from the Maasvlakte 2 harbor complex, where the Port of Rotterdam sits across from the Hook of Holland. This point is where some of the most important interactions between the North Sea and its neighbors are happening and will happen over the next three decades.

Maasvlakte 2 is a massive human intervention, another grand bargain between Dutch ingenuity and the sea: In exchange for not swallowing them in cold saltwater, the Netherlands promises the sea a modicum of foresight, hardheaded commercial instincts, and very good engineering. With 365 million cubic meters of sand, (more…)
