A one foot sub surface layer of large wood covered with small wood, leaves, chicken compost, and layered with the dug dirt a couple of times with more leaves, and extra dirt mounded up in the middle, and it all topped up with 30 years of soil building under a red-osier dogwood that was removed with fire a few years ago before it spread further.

Gateway to the #underworld: The enormous #permafrost '#megaslump' in #Siberia that keeps getting bigger

The growing "gateway to the underworld," officially known as the #BatagayMegaslump, is the largest megaslump in the world and exposes permafrost layers that are 650,000 years old.

"The 'gateway to the underworld' is a colossal, expanding crater in Siberia's permafrost. It is officially called the #Batagay (also spelled #Batagaika) crater or megaslump and formed when a portion of hillside in the #YanaUplands collapsed in the 1970s.

"However, the crater wasn't discovered until 1991, when satellite images revealed a rounded cliff face towering over a huge depression in the frigid landscape.

"The Batagay crater is the largest megaslump in the world, measuring 3,250 feet (990 meters) wide as of 2023. The cliff face at the top of the formation, or headwall, stands 180 feet (55 m) high.

"When it opened, the gateway exposed layers of permafrost that had been frozen for up to 650,000 years — the oldest permafrost in Siberia and the second-oldest in the world, after relict ground ice in #Canada's #YukonTerritory that is about 740,000 years old. Recently, researchers found that the gateway is expanding annually by about 35 million cubic feet (1 million cubic meters), with the depression sinking further into the ground and exposing new layers of ancient permafrost.

"The headwall of the gateway is also retreating at a rate of 40 feet (12 m) per year due to permafrost thaw, discharging massive amounts of ice and sediment into the crater, according to a 2024 study. Some of this melt material may remain in the crater, but #sediment and ice also washes into the #BatagayRiver valley at the far end of the gateway, researchers noted in the study.

"The permafrost in this region is 80% ice, which is likely why the hillside slumped in the first place, Thomas Opel, a paleoclimatologist at the Alfred Wegener Institute in Germany who has studied the gateway to the underworld, previously told Live Science.

"The gateway sits in a landscape of larch and birch #woodlands that became the target of #deforestation from the 1940s onward. Deforestation caused the #topsoil to rapidly erode and expose the underlying permafrost, which — due to its icy composition — melted more quickly than if it had been richer in sediments. Significant melting during the following decades caused the hillside to disintegrate and collapse, Opel said."

Agricultural Lands Are Losing Topsoil #agriculture #farming #topsoil #cartoon

2024-04-26

The mistakes we have been making in agriculture EXACTLY mirror the mistakes we've been making in society.

This may sound trite, but it's a VERY simple and blunt truth: the more diversity, the better. Whether we're talking about plants in the ground or people in your community. Without diversity, we will die.

The harder we try to exert control, the worse the consequences come back around to bite us in the ass. Whether this is about forcing crops to grow in straight lines and killing everything that isn't the desired product, or forcing people to behave in a certain manner-- it works the same way.

Hubris leads to unforseen consequences-- and keeps us repeating the same mistakes over and over and over again long past the time we should've learned better. The arrogance of insisting we know better than nature, the obsession with manipulation, keeps us from admitting conventional wisdom is flawed. Even when it is killing us.

We can do better.

The results sound too good to be true, and yet... The measurements are right there. Better than most of us would have ever imagined. Even with the proof RIGHT THERE on the farm next door, neighbors will still insist on sticking to the doomed methods we've been taught are the "best" way (indeed, entrenched obsolete agricultural policies will actually penalize doing anything differently).

This farmer got a kick start, when 4 years of total disasters kept him from harvesting anything from his ranch-- inadvertently resting and replenishing the depleted soil. He took a big risk, switching to no-till; he actually sold his tilling equipment in order to afford the no-till drill seeder.

His land is now 5x as fertile as that of his neighbors, and sits pretty while they flood in the rain.

No pesticides. No herbicides. No synthetic fertilizer. No ploughing.

Throughout this video, he keeps emphasizing how crucial it is to incorporate carbon into the soil-- for production, for profit. He's not even talking about atmospheric CO2-- it just so happens that sequestering carbon in living ecosystems is the best way to produce food.

Even though he's still probably a pretty conservative guy, still treating animals like walking coin purses, even he has been learning how to work WITH the land.

Why isn't this sort of thing all over the news? Why isn't it taught in every ag school? This video and others like it have been increasingly making the rounds, but...

When it DOES show up in the news, what do we see?

...Frightened, struggling, impoverished farmers protesting in horror because the government is restricting their fertilizer use.

Remember that poem about washing the dishes? And how if you drop one on the floor, maybe they won't tell you to wash the dishes anymore...?

When environmental policies are enacted, it works in much the same way as many policies for social justice-- if it's implemented in the worst ways, guaranteed to piss people off, it compromises the results. Then people can claim "See?? We tried! And it doesn't work!"

Command farmers to use less fertilizer without explaining WHY, without massive educational campaigns showing how regenerating the soil actually works, leading with punishment instead of excitement-- and the environmental effort is shot in the foot. Stirring up resentment against the whole idea. Protecting the companies that profit off the doomed status quo.

Same thing when drugs are decriminalized in some half-assed way WITHOUT implementing sufficient treatment programs. Same thing with some Affirmative Action over here but not touching the mass incarceration or poverty or other systemic drivers over there.

We can't halfass things anymore. We can't settle for the performative and poisoned false "reforms" that won't actually get the job done.

Real solutions take big changes. It takes thinking profoundly differently. Tear apart every unexamined assumption.

#Irresponsible #Land developers #bulldoze dozens of #acres of #trees and #plants that hold the #topsoil in place. Massive #flooding is the logical consequence.
#LandDevelopers expect you to eat the #bill when they #flood your #house.

It is possible to develop land without stripping the ground to the bare earth and burning everything left, as shocking an idea as that may be.

But when the article leaves open the question of "Who's Paying When They Flood Your House?"

it's you. What are you going to do? #Sue them? You'll never recover enough to matter, especially after fees.

Their plan is to fuck over everyone around them and not care what happens as a result, and they answer, effectively, to no one.

Don't contact your #representative over #counties communicating, ask them to #ban this #dangerous and #destructive practice throughout the #state of #Florida.

Meeting material needs should come without health risks or #environmental costs. No human activity should lead to #habitat destruction, #deforestation, contamination, #topsoil loss, #erosion, or damage to earth’s surface and subsurface. People must be able to occupy an area without creating a lasting footprint. Non-destructive resourcing is lightweight, responsive, interconnected, and fully removable—leaving an area as if in a pre-human state.

Topsoil loss is a major threat to food security and the environment in the Midwest, where conventional farming practices erode the fertile layer of soil. A new study shows that adopting no-till farming, which avoids ploughing and disturbing the soil, could stop topsoil loss and even restore it over time. The study estimates that no-till farming could save up to 3.5 billion tons of topsoil per year in the region.

"The Midwestern United States has lost 57.6 billion tons of due to farming practices over the past 160 years, and the rate of is 25 times higher than the rate at which topsoil forms.

can extend our current level of fertility for the next several centuries. This has implications for everything from food security to mitigation."
