Greening the Desert? Not So Fast!

John Wesley Powell (Wikipedia.org)

When Marc Reisner published his groundbreaking — and self-proclaimed apocalyptic — analysis of the West’s water woes in 1986, geographic information systems were in their infancy and climate forecasting models could take months to run. Not that Reisner’s predictions in Cadillac Desert: The American West and its Disappearing Water were without merit. Indeed, his concerns that water shortages would pit urban population growth against food production are fast becoming a reality. At the time of publication, Reisner’s text wasn’t viewed as a scientific piece of work, but it did make ... Read More

The Torpedo

Bell Biv DeVoe, R&B spin-off group from the early 1990s, hit it big with smash single, “Poison.” Chances are that while the group crooned “Girl, I must warn you,” it was unaware of the predatory microbe Bdellovibrio bacteriovorus. This unique genus of gram-negative aerobic bacteria will invade and, in most cases, devour its prey entirely. (Gram-positive bacteria — named for the test that identified them — feature a thick cellular wall of protein and sugar compounds that helps store energy and provides structural strength.) Found in ocean and fresh water, sewage, soil and ... Read More

Rocky Mountain Dust-up: Runoff’s Dirty Secret

Climate Change, Snowmelt

Every time the winds blow east from the deserts of the Southwest, it means less water for 27 million people who depend on the Colorado River. Layers of dust form every year on snowfields in the Rocky Mountains, blown in from pastures, farms, dirt roads and off-road vehicle parks. For decades, according to a study released this week by the National Academy of Sciences, this dust on snow both accelerates the annual runoff by weeks and reduces what reaches the Colorado River by 5 percent. Clean snow reflects about 80 percent of the sunlight that hits it. But in the high Rockies, dust on ... Read More

The Real Revenge of Montezuma: Voyage Conclusions

Flooding

Location: In Mazunte, just north of Huatulco. Through scattered clouds, the morning sun shines on the bay, whose centerpiece is a pair of jagged boulders. The rocks are frothy with crashing waves and soft backlight. The bay is surrounded by swaying palm trees and a snaking wetland. Conditions: From inside my swinging cot, hanging freely from a roof covered by a mosquito net, I can tell the morning air is starting to warm up. It's 8 a.m., and the septic tank truck is already pumping sewage and someone is running a drill. Fishermen are pushing their pangas past the tiny waves. Discussion: ... Read More

The Balance of Evil-Doing: Kiri’s Impacts

Let an admission of hypocrisy herald the end of my three-month voyage from California to southern Mexico: I used a lot of petroleum. The V8 Ford van that I drove, also known as El Hippo (why the name? see side note), had a hunger that was hard to contain. It got a pathetic 12 miles per gallon. Here I am, exploring the effects of climate, advocating solutions to improve the resilience of coastal communities, yet I'm also part of the problem. Nevertheless, as economics teaches us, the true cost depends on the alternatives. So, as an aspiring do-gooder, I'd like to know, "What is the balance ... Read More

Diving Deeper into Searsville

A graph showing dams in the United States by completion date. Click to Enlarge

Young women, ebullient and dripping, stand in a line along the concrete walkway above Searsville Dam. Beneath their naked feet, a sheet of water rushes under the platform and arches briefly into open space. The sheet breaks up, falls flickering against the face of the dam, and tumbles toward a shallow pool 60 feet below. Above the women's capped heads, cottony clouds reflect down on the surface of the reservoir. Downstream, San Francisquito Creek winds its way unseen through thick oak trees and city streets to San Francisco Bay some 5 miles below. Upstream, tens of miles of tributaries cut ... Read More

The Big Friendly Giants of Escuinapa

mmw_roalddahlBFG

In mid-May of this year, an entire town moved to the beach for five days of partying. School was canceled and work was deferred for the thousands attending the annual Fiesta de Mar de las Cabras. They came mostly from Escuinapa, a town located one hour south of Mazatlán and 20 minutes inland from Playa Cabras. According to organizers, it is the 105th year of the event, which had roots as an indigenous "pagan" festival to celebrate the sun god Yequi. Kids, parents and grannies listen to live music on the isolated beach. There is nothing around for miles except coconut trees and two ... Read More

The Pearls of La Paz

In La Paz in Baja California, our Kiri blogger attends the Waterkeeper Alliance conference and learns about hopes for improving coastal areas. Location: Near the beach at Balandra, southeast of La Paz; a bay and wetland complex that was submitted for protected area status by La Paz residents. Conditions: Hot and dry winds are gusty at night and calm during the morning. The water is cool and pleasant for swimming. Isla Espiritu Santo glimmers in the horizon as sailboats go by. Discussion: La Paz was once rich in pearls. Expeditions financed by Hernán Cortés in the 1530s came back ... Read More

Sustainable or Sick: the Growth of Loreto

The mural on the waterfront colors the open air structure for the sewage-pumping system. (Kristian Beadle)

Location: Hotel San Carlos in Loreto, southern Baja, two blocks from the waterfront. Conditions: Outside, the sun is shining, but I'm lying in my room feeling nauseous, suffering through my first stomach bug this trip. Discussion: Imagine saying, "Honey, the water truck is coming!" Then your husband puts down the breakfast cereal and bolts out the door to catch the truck, waving money to indicate he is worth the driver's time. Pamela Bolles, a Loreto resident for 11 years, explained: "The truck used to come three times a week, now it's every 10 days, if we're lucky. We need to be on our ... Read More

The Great Floods of Mulegé

The damaged bridge after Hurricane Jimena unleashed floodwaters. This bridge was completely engulfed. (Kristian Beadle)

Voyage of Kiri blogger Kristian Beadle sees firshand the effects of water from the sky impacting water on the ground. Location: At the river mouth in Mulegé, a town on the fourth largest oasis in Baja. The green river winds past palm trees before opening into the Sea of Cortéz. Conditions: Humid with the buzz of crickets and mosquitoes. Bougainvilleas and trees filter the morning light. Discussion: "The water was up to here," said Saul Davis, pointing above his head at a mark on the wall. "There was mud everywhere." Davis is the charismatic owner of a small market in Mulegé, a town ... Read More
