Urban Agriculture in Mexico City: Healthy and Necessary

by Devon G. Peña

The Colhua Mexica (Aztec) twin island cities of Tenochtitlan and Tlatelolco were filled with urban farms, home kitchen gardens, fish-stocked ponds, and aviaries. Two large lakes south of the cities were filled with highly productive floating gardens known aschinampas. These ancient Mesoamerican city-states were basically food self-sufficient. The conquest destroyed most of these cultural ecological landscapes and built Mexico City with the rubble of demolished temples, schools, colleges, homes, and other buildings. Mexico City has never been able to reproduce this ideal condition of food self-sufficiency and instead basically sucks the energy out of the Mexican countryside and — ever since NAFTA — from fresh produce and processed food imported or manufactured with ingredients from the U.S. and other countries.

A Naturalist’s Reflections on the Yarnell Fire

by Walt Anderson

Nine months after the tragic Yarnell Hill Fire on June 30, 2013, the event continues to touch many of us with a rawness only slightly softened by time.  My memories remain vivid.  With thunderstorm activity developing in the Prescott area that afternoon, Cactus cross, a burn survivorI grabbed my camera and headed out to the Doce Fire area south of Granite Mountain.  Fierce little rain squalls gave me subjects to explore visually.  The powdered ash deposits post-fire are very vulnerable to erosion, a step in the ecologic process I wanted to capture.

Then as a squall shifted south, I could see in the distance a column of smoke that caused my hair to rise — it appeared to me that the small town of Yarnell was on fire.  Without hesitation, I leaped into the car and shot toward Skull Valley, having to slow down once in the midst of an intense downpour.  The closer I got to Peeple’s Valley, the more my concern intensified, and I made a decision that gave me a perfect vantage point on a ridge north of the fire.  If I had continued any farther down the highway, I would have been stopped by emergency vehicles and stuck in a line of other cars prohibited from moving farther.

Walk Softly

Toward a Profound Reverence for Planetary Balance…

by Robert C. Koehler

“When you go to dig your fields, or make a pot from clay, you are disturbing the balance of things. When you walk, you are moving the air, breathing it in and out. Therefore you must make payments.”

Oh, unraveling planet, exploited, polluted, overrun with berserk human technology. How does one face it with anything other than rage and despair, which quickly harden into cynicism? And cynicism is just another word for helplessness.

So I listen to the Arhuaco people of northern Colombia, quoted above at the Survival International website, and imagine — or try to imagine — a reverence for planetary balance so profound I am aware that when I walk I disturb it, so I must walk with gratitude and a sense of indebtedness. Walk softly, walk softly . . .

Instead, I live in this world: (more…)

The Carbon Crisis

Can We Fix Humanity’s ‘Biggest Mistake’ in Time?

by Kent Shifferd

The great release of carbon-based energy began in the second half of the eighteenth century, prompting the poet William Blake to coin his famous line about “England’s dark, satanic mills.” All history before that was characterized by an organic tool kit. Our technology was mostly biodegradable and not very powerful. Nature was strong — humanity was weak. I am not suggesting we want to revert to that relationship, but did we go in the right direction, and if not, what can we do about it now?

Why was the release of carbon energies humanity’s greatest mistake? The answer is simple; it has led to the severe damage to the biosphere we now see all around us. The biosphere, that thin zone of life that surrounds the earth like the skin on an apple, is the only place in this solar system that we can live and we are utterly dependent upon its natural processes. It provides oxygen to breathe, water to drink, and soil that produces all our food. As everyone knows, it is a vastly complicated, living web whose interconnections we will never fully understand. The release of carbon energy has made it possible for us to recklessly pull apart the strands. (more…)

Water World

Are We Approaching a Global ‘Cadillac Desert’?

by Evaggelos Vallianatos

Water for the Greeks was the immortal natural world. The supreme Greek god, Zeus, sent rains; Poseidon, brother of Zeus, was the god of the oceans and seas; Metis, daughter of the Ocean River god and first wife of Zeus, was goddess of intelligence and mother of Athena, goddess of the arts of civilization.

Homer said the god of metallurgy, Hephaistos, sculpted the great Ocean River surrounding the Earth on the outermost rim of Achilleus’ shield. Achilleus, son of a water nymph, was the Greeks’ greatest hero during the Trojan War.

And the first Greek natural philosopher, Thales, proposed in the seventh century BCE that water was the stuff of life and the cosmos. (more…)

On the Value of Our Social Movements

by Chellis Glendinning 

(To Elizabeth Hallett, who has devoted her life to social change and caring for the wounded.)

It’s yet another bloqueo, paro y huelga in Bolivia, nary a week passes without one or two or three somewhere in the country. The syndicates, collectives, and communities are in the streets marching, striking, blocking traffic with boulders and tires, hurling rocks at the police, shooting firecrackers, martyring themselves in hunger strikes — causing havoc, threatening the national economy, pushing the blind eye of government to see their demands. All the while, activists, protestors, and anti-globalization visionaries in “advanced” societies are stunned, inspired, awed. And green with envy.

The campesinos and city folk in Cochabamba’s 2000 Water War, after all, put a stop to an already-signed contract with mega-corporation Bechtel to privatize water sources and delivery, while those in the 2003 Gas War in El Alto brought down a government.

Yes, green with envy. (more…)

Succession

October 28, 2013 By: NCVeditor Category: Culture, Ecology, Victor Postnikov

Toward Harmonious and Stable Co-Existence

by V.I. Postnikov

Loitering the central streets of my native town, Kiev, where I had lived for 63 years, I involuntarily examine the passers-by.  Gosh, how changed the appearance of citizens! I notice some subspecies that I never met before — such as a subspecies of managers — short-Imagehaired young people in white shirts, a subspecies of guards — stern-looking lads with bull’s napes,  a subspecies of builders — lads from other towns. The old age people are rarely seen on the streets.  I peer at the faces, hoping to recognize familiar ones. But no, no way, they are all long gone.  The species, the environment have changed irrevocably. Sad, but true.

In ecology, there is the concept of “succession,”  an important term which explains serial mutability of a species and its habitat. William R. Catton, Jr., in his classic book Overshoot, shows how this principle works in the human environment [1].  To understand the succession in human society, it is useful to first consider nature’s succession.
